3.3.2 Oscillating Lock Mechanism Because the right and left oscillating cylinders work together as a hydraulic linking circuit, the right and left crawlers oscillate in reverse directions and against each other, according to the unevenness of the ground. That increases stability when moving over unleveled ground. The automatic oscillating lock mechanism changes the hydraulic linking circuit (LOCK - OPEN), automatically linking to the traveling levers and the oscillating switch. ★ For the operation of the oscillating switch, refer to 3.6.2 “Hydraulic Cylinder Control Panel”.

LOCK When the travel levers or the oscillating switch is not operated then the left and right track frames can't be oscillated.

OPEN When traveling, or operating the oscillating lever, oscillation of the left and right track frames is available. Because the right and left oscillating cylinders work together as a hydraulic connecting circuit, the right and left track frames oscillate in reverse directions and against each other, according to the unevenness of the ground. That increases stability when moving over unleveled ground. ★ When the boom swings in 15° or more against the main

body, oscillating is not possible. (HCR1500-ED)

17305002

17305003

If the right and left truck frames are not oscillating during the machine traveling, stop moving and ask your nearest distributor to check and restore it.

When operating such equipment as the boom or guide shell, make sure that the right and left crawler track shoes are both touching the ground otherwise it might tip the machine over.

3. Feed Speed Adjusting Dial This dial adjusts the drifter feed forward speed in drilling. This dial is used to adjust the drifter’s feed forward speed during drilling. When the feed speed is slower than the drilling speed, idle blows tend to occur in the drifter. If idle blows occur in the drifter, increase the feed speed. When the feed speed is too fast for the drilling speed, hole bend or jamming may occur if the drill encounters soft rock, fracture zone, or hollow. Adjust the feed forward speed, paying attention to changes in drilling sound and rotation pressure. Pull the dial, and release the lock. Turn the dial clockwise to increase the drifter’s forward speed. Turn the dial counterclockwise to decrease the drifter’s forward speed. After adjusting, push the dial. 4. Feed Pressure Control Dial

This dial adjusts the force of the feed pressure when drilling. This dial is used to adjust the feed pressure force during drilling. By adjusting the feed pressure force, such irregularities as hole bend and rod damage are prevented. Generally, when the rock drilled is hard or large diameter drilling performed, the feed pressure force is increased, and when soft rock is drilled or small diameter drilling is performed, the feed pressure force is decreased.

WARNING


3-6-5

Feed Operation Feed operation is performed in order to move the drifter forward or backward and for fast feed operation. 2-step change can be carried out for each work. Forward Pulling the control grip one step to this side shifts to normal feed where the drifter is slowly fed forward. When it is pulled to the end of this side, the drifter is fed fast forward. Backward Pushing the control grip one step to the machine front side shifts to normal feed where the drifter is fed backward slowly. When pushed to the end of the machine front, the drifter is fed fast backward. The drifter can be stopped both during normal feed forward and backward. When the hand is released from the fast forward or backward position, the grip automatically returns to the normal feed forward or backward position.

Rotation Operation The rotation switch (B) is used to turn the drifter shank rod normally (counterclockwise) or reversely (clockwise). Normal Rotation When the left-hand side of the rotation switch (B) is pressed once, the shank rod is turned normally. When pressed again the rotation is stopped. Reverse Rotation As long as the right side of the rotation switch (B) is pressed and held, the shank rod is turned reversely. When the finger is released the rotation is stopped.

3.13.1 Handling of Fire Extinguisher The fire extinguisher in the machine is effective for the following: General Fire: fiber, paper and wood fires. Oil Fire: Diesel and other such oil fires. Electric Fire: Fire in electrical equipment with a risk of shock.

Precautions in Extinguishing Fire

The forcible use might increase the fire. It may not be possible to use the extinguisher to deal with a large fire or to use the extinguisher fast enough. The fire extinguishing should be from the windward so that gases are not inhaled. Tilting the extinguisher reduces its efficiency. Keep it as straight upright as possible. The fire extinguishing liquid is electric conductive. In order to prevent a short circuit or electric

shock; turn off the power when fighting fire electrical equipment. In fire fighting, approach the fire gradually keeping back 3 m after the fire is reduced. When fighting fire always keep open an escape route.

CX15004

Do not disassemble the fire extinguisher: the container might burst.

The life period of the fire extinguisher is about 8 years. When the hand of the pressure gauge (1) is not within the green range, there is rust or scratching on the container, or the hose is degraded: replace the fire extinguisher by new one. If the fire extinguishing liquid gets into your eyes or on your skin, wash it well off with clean running water and consult your doctor.

Drilling Precautions Beware with Blow Up of Cuttings

Check if cuttings are blows up by means of flushing air during drilling. If the blowhole at the bit tip is stuffed, the flushing air pressure is increased. If the blowout of the flushing air becomes weak, cuttings cannot be discharged normally to easily result in hole stuffing and jamming. ★ When the anti-jamming switch is set to [I] or [II], the drifter moves backward automatically when

the flushing air pressure has increased, or the airflow has dropped due to stuffing of bit tip. Clean the Drilling Hole

If the cuttings cannot be discharged normally or the flushing air pressure increases, stop the impact and move the drifter up and down 2 – 3 times to clean the hole before re-starting drilling. ★ When the anti-jamming switch is set to [II], the drifter is automatically stopped moving forward if

the rotation pressure is excessively increased. Beware of Spring Water

If dirty water is collected, the filter element in the dust collector may be clogged and dust collection degraded. If spring water comes out during drilling, tilt the flushing lever to the left and stop the dust collector operation.

4.6.4 Using Anti-Jamming Controller ★ For adjustment of the anti-jamming controller, refer to the “Adjustment Instruction Manual”

(separate volume). Generally, in drilling, if the rock is hard the rotation pressure should be set to high and if the rock is soft it should be set to low. For efficient drilling, if the rock is soft and the rotation pressure is high, the feed pressure and impact pressure should be set to low: if the rock is hard and the rotation pressure is low, the feed and impact pressures should be set to high. When drilling with the anti-jamming controller on, set the mode selector switch to N mode and the anti-jamming switch to [III]. Set the guide shell at drilling position while performing impact and rotation, and then turn the control grip to the regular drilling position. The rotation, feed, impact and damper pressures are detected and each pressure is controlled so as to optimize drilling in changing rock quality and rock bed. Automatic drilling is available by activating the anti-jamming controller. ★ For the anti-jamming switch, refer to 3.7.1 “Control Panel”.

Before activating the anti-jamming controller in drilling, reset the anti-jamming control and adjust the machine for smooth drilling. To adjust the anti-jamming controller, ask your nearest distributor.

4.6.5 End of Drilling Work Mounting and Dismounting the Rods

The rods are added to each other, and drawn by loosening screws of the sleeves and rods by means of rotation-free impact after the end of all drilling work. These rods are mounted and dismounted by operating the rod changer without any direct handling of these rods by a worker. ★ For the levers and switches in rotation-free impact, refer to

the right figure. 1. After drilling return all operation levers and switches,

except for the anti-jamming switch (1), to NEUTRAL or OFF.

2. Tilt the flushing lever (2) to this side. 17310086

Long time no-rotation free-impact causes the bit and rod to slip off. When the screw is loosened in the rod or sleeve, the impacting sound is changed. Pay attention to the impacting sound during rotation-free impact.

Inspection after Drilling Work After drilling, check each part of the machine, to maintain the machine safety and avoid breakdown. 1. Look around the machine to check for oil leakage and visible damage. 2. Check the boom and boom mounting part for deformation and damage. 3. Check the bit for excessive wear and damage. 4. Check the guide shell for deformation and damage. 5. Check the drifter for visible damage, leakage and damage to fittings. 6. Check the joints of high-pressure hose and hoses for proper connection and leakage. 7. Check the rod changer for excessive oil leak, excessive deformation, and damage. 8. Check the rods for bending, damage, cracking, other defects, or wear of threaded sections. 9. Check the engine room inside for loose or missing parts and oil leakage. 10. Check the carriage and remove mud.

If there is any abnormality perform maintenance or repair and replace the faulty component.

4.7 Rod Changer Operation In the following chapter, the rod changer operations of the pull-drilling specification and push-drilling specification are explained separately. ★ For the operation in pull-drilling specification, refer to 4.7.1 “Pull-drilling Specification”. ★ For the operation in push-drilling specification, refer to 4.7.2 “Push-drilling Specification”.

Do not touch any rotation section such as the rod (1), sleeve (2) or shank rod (3) during rod changer or drifter operation; otherwise your finger or other part of your body might be caught. If your finger or other part of your body is caught by the moving part of the centralizer (4), it causes cutting or crushing. When the centralizer (4) is opened or closed to install or remove the sleeve (2), decide upon signals between the operator and other workers to avoid being caught by the centralizer (4). If the control grip is operated wrongly, an accident resulting in injury or death may occur. Before operating the rod changer, check the drilling method.

Towing

5-2-1

5.2 Towing Don't tow the machine except where it can't move under its own power, due to breakdown of the drive motor or malfunction of the hydraulic system. If it can’t move, release the parking brake before starting its towing. When the machine is towed, take care of the following:

Tow the machine with it set to "traveling posture”. Movement of a towed machine should only be for checking or maintenance.

Do not tow the machine more than 100m. If a longer distance is required, transport it on a vehicle such as a trailer.

Tow the machine at 2km/h or less, otherwise the drive motor might seize. Use a tow wire rope of 1.5 times or more of the strength needed to tow a vehicle of the mass of

the machine to be towed. Do not use a twisted or kinked wire rope. Do not use a chain to tow the machine because a link might break. The size of the tractor should be equivalent to or larger than the machine to be towed. Move and set the wire rope so that the coupling section of the tractor is aligned with the

attachment to the machine. Before towing, make sure there is nobody between the tractor and the machine. If the tractor moves suddenly the wire rope might break.

Operate the tractor slowly and at a steady speed. Do not tow the machine on sloping ground because the machine might run away under its own

mass.

Incorrect towing of the machine that can’t move under its own power is very dangerous and might cause accidents resulting in injury or death. When the machine is to be towed, comply with the following precautions.

Battery Servicing

6-3-2

In Cold Weather If the temperature falls, the performance of the battery is degraded. If the charge rate is low the battery electrolyte might be frozen. Keep the charge rate always near to 100%. Replenish with distilled water before work (or before charging) to prevent freezing.

In Hot Weather If the temperature rises, water in the battery fluid tends evaporate. If the battery electrolyte become low the plates might be damaged and the life of the battery might shortened. Before engine start, check the battery electrolyte level.

Check Electrolyte Specific Gravity Measuring the specific gravity of battery electrolyte can indicate the charge rate. Check specific gravity of electrolyte in each battery cell with hydrometer. The relationship between the electrolyte specific gravity and the battery conditions are as follows:

6-3-5

Precautions in Battery Change The battery is very heavy.

When the battery is removed or installed, use a lifting machine such as a crane. The nylon sling to be used for lifting the battery should be adequate for the battery mass. When the battery is to be replaced, replace both batteries at the same time with the same type.

Using Battery Charger Do not use the battery charger as a booster if a battery has a 1.230 specific gravity reading or

lower. Turn off the battery charger before connecting or disconnecting it. An explosive gas is produced while the batteries are in use or being charged.

Keep flames or sparks away from the battery area. Charge the batteries in a well-ventilated area.

Connect the batteries in the correct polarity (positive (+) to positive (+) and negative (-) to negative (-)).

Disconnect the battery ground wire before you charge the battery in the machine to prevent damage to electrical equipment.

Do not charges a battery if the battery is frozen or the battery may explode.

Engine Start When the engine is to be started: Start-up takes no more than 10 seconds. If the engine does not start within that time, re-start more than 2 minutes later. If this is repeated 5 - 6 times and the engine still does not start, check the battery and engine electric circuit.

6.3.2 Using Booster Batteries

17310098

Battery gas can explode. When the battery clamps are connected, do not connect the positive (+) to the negative (-), otherwise a spark might explode the battery. When starting from another machine, never allow machines or booster cable clamps to touch each other. This prevents sparks near the battery, which could ignite hydrogen gas given off the battery, causing the battery to explode.

Always turn the starter switch kept to OFF position before connecting booster batteries. When using booster batteries, be sure to wear glasses to protect your eyes from sparks. Connect the booster cables correctly. POSITIVE (+) to POSITIVE (+) and NEGATIVE (-) to NEGATIVE (-). To prevent sparking around the battery, connect clamp to rear frame as far from the battery as possible and remove paint. Do not attempt to jump-start the machine with frozen batteries. The battery could rupture and explode. If you suspect a frozen battery, remove vent caps and check the fluid. If there seems to be no fluid or if you see ice, do not attempt a jumper start until fluid thaws.

7. Operation in Cold Weather In extremely cold weather conditions, special measures should be taken to operate the machine.

Fuel Oil Use fuel oil appropriate to atmospheric temperature. Open the drain cock of fuel tank to drain out water periodically. Fill the fuel tank as much as possible.

Engine Oil Use oil viscosity meets for atmospheric temperature.

Battery The battery capacity will decrease as atmospheric temperature falls. Keep the battery fully charged at all times. If the battery is not to be used during cold weather, remove the battery and store it indoors. After distilled water has been added or, when specific gravity is very low, discharged the battery could freeze.

Coolant If the radiator cooling water does not contain the anti-freeze, fully drain out the cooling water in advance when storing the machine in cold weather. No draining is required if the anti-freeze is mixed.

Precautions for Operation As any ice or dirt on the piston rod of the hydraulic cylinder might damage the seal, wipe it out

carefully. In extremely cold weather, the tracks may freeze to the ground and cannot move occasionally

after operation. Do not place the machine directly on the ground, but place it on wood or concrete blocks.

11-1-1

11. Fuels and Lubricants 11.1 Emergency Measures

First Aid If fuel or lubricant accidentally splashed in your eyes, flush eyes with water for 15 minutes.

Get medical attention immediately. If it gets on your skin, wash it with soap and water. If you inhale it, go out into fresh air and keep warm with your body wrapped in a blanket.

Keep quiets and get medical attention immediately. If you drink it, do not force yourself to vomit. Get medical attention immediately.

If inside of your mouth is contaminated, wash with large amount of water.

Treatment for Leakage If fuel or lubricant leaks, do not send it into the sewage system or river, so that secondary disaster or environmental pollution is not caused.

Find the leakage point and stop leaking. Prepare such fire extinguishing equipment as a fire extinguisher. Do not allow any burning cigarette, spark or naked flame close to the leaking point. Use protective gear with good conductivity in order not to generate static electricity. If required, wear a gas mask. If the leakage is small, dry it with soil, saw dust or a rag. If the leakage is large, contain the flow by surrounding it with soil. Cover the liquid's surface with

bubble fire extinguishing liquid and retrieve it in an empty container. If leakage occurs indoors, ventilate the room by opening windows and doors.

Measures in Fire Wear protective gear for fire extinguishing, such as a gas mask and protective gloves and

extinguish the fire from the windward. Stop everybody except for the fire fighters from coming near the fire. Fire extinguishing with bubble fire extinguishing liquid and intercepting air is effective.

Do not use water because it might spread the fire. Sprinkle water around the origin of a fire to cool the spot and prevent the spread of a fire.

Careless handling of fuels and lubricants might cause not only environmental destruction, but also accident resulting in injury or death. Take the greatest care in handling fuels and lubricants.

11.2 Fuel Fuel Specifications

The following specific natures are required for the diesel fuel. Must be free from minute dust particles. Must have adequate viscosity. Must have high cetane value. Must have high fluidity at low temperature. Muse is less sulfur content. Must have little residual carbon.

Caterpillar recommends the use of fuel meeting the Grade No.2-D requirements of the American Society for Testing and Materials (ASTM) D975, Standard Specifications for Diesel Fuel Oils. At operating temperatures below 0°C, use a blend of No.1-D and No.2-D fuels, also know as “winterized” No.2-D. ★ For a more detailed description of fuel properties, refer to Operation and Maintenance Manual of

Caterpillar C9 Engine. Fuel Storage

The engine fuel injection pump and nozzle are sensitive components. Any fuel with water or dust will cause them to break down. In handling fuel, comply with the following: Fill the fuel tank at the end of operation. Keep fuel in a clean fuel storage tank in a protected area. Drain water and sediment from the fuel storage tank weekly.

Drain water and sediment before the tank is refilled. If possible, install a water separator at the fuel storage tank outlet. Keep the area around the fuel tank filler neck clean of debris in order to prevent contamination of

the fuel tank. Drain water and sediment from the fuel tank daily.

Do not use de-icers to remove water from fuel. Do not depend on fuel filters to remove water. Before the engine is started, drain any water and sediment accumulated at the bottom of the fuel

tank.

The diesel fuel quality greatly affects the performance and life of the engine. Use only clean, high quality fuel.
