CHAPTER 2

SAFETYThis safety alert symbol means Attention! Become alert! Your safety isinvolved! It stresses an attitude of Heads Up for Safety and can be

found throughout this Operators Manual and on the decals on the machine.

Before operating this machine, read and study the following safety information.For further reference on the safe operation of skid-steer loaders, Mustang Manu-caturing Company suggests that equipment owners obtain the Mustang Skid-Steer Loader Safety video, which is available through Mustang dealers. In addi-tion, be sure that everyone who operates or works with this machine, whetherfamily member or employee, is familiar with these safety precautions. It is essen-tial to have competent and careful operators, who are not physically or mentallyimpaired, and who are thoroughly trained in the safe operation of the machineand the handling of loads. It is recommended that the operator be capable ofobtaining a valid motor vehicle operators license.

The use of skid-steer loaders is subject to certain hazards that cannot be eliminatedby mechanical means, but only by exercising intelligence, care and common sense.Such hazards include, but are not limited to, hillside operation, overloading, insta-bility of the load, poor maintenance and using the equipment for a purpose forwhich it is not intended or designed.

Mustang Manufacturing Company ALWAYS considers the operators safetywhen designing its machinery, and guards exposed moving parts for the oper-ators protection. However, some areas cannot be guarded or shielded in order toassure proper operation. Furthermore, this Operators Manual and decals on themachine warn of additional hazards and they should be read and observedclosely.

Some photographs in this manual may show doors, guards and shields open or

removed for illustrative purposes only. Be sure that all doors, guards and shieldsare in their proper operating positions before starting the engine to operate theunit.

Different applications may require optional safety equipment, such as a back-upalarm, mirror, strobe light or an impact-resistant front door. Be sure you know thejob site hazards and equip your machine as needed.

DANGER indicates an imminently haz-ardous situation which, if not avoided, will

result in death or serious injury.

WARNING indicates a potentially hazardoussituation which, if not avoided, could result in

death or serious injury.

CAUTION indicates a potentially hazardoussituation which, if not avoided may result in

minor or moderate injury. May also alert against unsafe practices.

Mandatory Safety Shutdown Procedure

Before cleaning, adjusting, lubricating, servicing the unit, or leaving it

unattended:

1. Move the drive control handle(s) to the neutral position.

2. Lower the lift arm and attachment completely. If the lift arm mustbe left inthe raised position, BE SURE to properly engage the lift arm support device(page 20).

3. Move the throttle to the low idle position, shut off the engine and remove thekey.

4. Before exiting, move the lift/tilt control(s) to verify that the controls do notcause movement of the lift arm or attachment.

Safety Reminders

Before Starting Do not modify the ROPS/FOPS unless instructed to do so in installation

instructions. Modifications such as welding, drilling or cutting can weakenthe structure and reduce the protection it provides. A damaged ROPS/FOPScannot be repaired it must be replaced.

To ensure safe operation, replace damaged or worn-out parts with genuineMustang service parts.

Mustang skid-steer loaders are designed and intended to be used only withMustang attachments or approved referral attachments. Mustang Manufac-turing Company cannot be responsible for operator safety if the loader is usedwith a non-approved attachment.

Remove all trash and debris from the machine each day, especially in theengine compartment, to minimize the risk of fire.

Always face the loader and use the handholds and steps when getting on andoff the loader. Do not jump off the loader.

Never use starting fluid (ether).

Walk around the machine and warn all nearby personnel before starting themachine.

Always perform a daily inspection of the machine before using it. Look fordamage, loose or missing parts, leaks, etc.

917179/CP0107 7

During Operation

Machine stability is affected by: the load being carried, the height of the load,

machine speed, abrupt control movements and driving over uneven terrain.DISREGARDING ANY OF THESE FACTORS CAN CAUSE THELOADER TO TIP, THROWING THE OPERATOR OUT OF THESEAT OR LOADER, RESULTING IN DEATH OR SERIOUS INJURY.Therefore: ALWAYS operate with the seatbelt fastened and the restraint barlowered. Do not exceed the machines Rated Operating Load. Carry the loadlow. Move the controls smoothly and gradually, and operate at speeds appro-priate for the conditions.

When operating on inclines or ramps, always travel with the heavier end ofthe loader toward the top of the incline for additional stability.

Do not raise or drop a loaded bucket or fork suddenly. Abrupt movementsunder load can cause serious instability.

Never activate the float function with the bucket or attachment loaded or

raised, because this will cause the arm to lower rapidly. Do not drive too close to an excavation or ditch; be sure that the surrounding

ground has adequate strength to support the weight of the loader and the load.

Never carry riders. Do not allow others to ride on the machine or attachments,because they could fall or cause an accident.

Always look to the rear before backing up the skid-steer loader.

Operate the controls only from the operators seat.

Always keep hands and feet inside the operators compartment while oper-ating the machine.

New operators must operate the loader in an open area away from bystanders.Practice with the controls until the loader can be operated safely andefficiently.

Always wear safety goggles, ear and head protection while operating themachine. Operator must wear protective clothing when appropriate.

Exhaust fumes can kill. Do not operate this machine in an enclosed areaunless there is adequate ventilation.

When you park the machine and before you leave the seat, check the restraintbar for proper operation. The restraint bar, when raised, deactivates the lift/tiltcontrols and auxiliary hydraulics, and applies the parking brake.

Maintenance

Never attempt to by-pass the keyswitch to start the engine. Use only the jumpstarting procedure detailed in the Operationchapter of this manual.

Never use your hands to search for hydraulic fluid leaks. Instead, use a pieceof paper or cardboard. Escaping fluid under pressure can be invisible and can

penetrate the skin and cause serious injury. If any fluid is injected into yourskin, see a doctor at once. Injected fluid must be surgically removed by adoctor or gangrene may result.

8/10/2019 Mustang 2066

12/88

Always wear safety glasses with side shields when striking metal againstmetal. In addition, it is recommended that a softer (chip-resistant) material beused to cushion the blow. Failure to heed could lead to serious injury to the

eyes or other parts of the body.

Do not smoke or have any spark-producing equipment in the area while fillingthe fuel tank or while working on the fuel or hydraulic systems.

Potential Hazards

A skid-steer loader operator must ALWAYS be conscious of the working environ-ment. Operator actions, environmental conditions and the job being done requirethe full attention of the operator so that safety precautions can be taken.

ALWAYS maintain a safe distance from electric power lines and avoid contactwith any electrically charged conductor or gas line. Accidental contact or rupturecan result in electrocution or an explosion. Contact the North American One-CallReferral System at: 1-888-258-0808 for the local Digger's Hotline number orthe proper local authorities for utility line locations BEFORE starting to dig!

Exposure to crystalline silica (found in sand, soil and rocks) has been associatedwith silicosis, a debilitating and often fatal lung disease. A Hazard Review(Pub. No. 2002-129) by the U.S. National Institute for Occupational Safety andHealth (NIOSH) indicates a significant risk of chronic silicosis for workersexposed to inhaled crystalline silica over a working lifetime. NIOSH recom-mends an exposure limit of 0.05 mg/m3as a time-weighted average for up to a10-hr workday during a 40-hr workweek. NIOSH also recommends substitutingless hazardous materials when feasible, using respiratory protection and regularmedical examinations for exposed workers.

Safety Decals

The skid-steer loader has decals that provide safety information and precautionsaround the loader. These decals must be kept legible. If missing or illegible, theymust be replaced promptly. Replacements can be obtained from your Mustangdealer. New equipment must have all decals specified by the manufactureraffixed in their proper locations.

New Decal Application

Surfaces must be free of dirt, dust, grease and foreign material before applyingthe decal. Remove the smaller portion of the decal backing paper and apply theexposed adhesive to the clean surface, maintaining proper position and align-ment. Peel the rest of the backing paper and apply hand pressure to smooth outthe decal surface. Refer to the following pages for proper decal locations. Textdecals begin on page 9; no-text decals begin on page 12.

T-Bar Controls

The Mustang loader may be equipped

with the T-Bar control option. The leftT-Bar controls the drive and the rightT-Bar controls the lift/tilt.

Drive Controls

Forward, reverse, speed and turningmaneuvers are controlled by movement ofthe left T-Bar. To go forward, push thecontrol forward; for reverse, pull the con-trol rearward. To turn right, twist the con-trol clockwise; to turn left, twist the con-trol counterclockwise. For gradual turns, twist the T-Bar slightly clockwise orcounterclockwise. For sharp turns, twist the control fully clockwise or counter-

clockwise.Moving the T-Bar farther from neutral increases the speed steadily to the max-imum travel speed. Tractive effort decreases as speed increases. For maximumtractive effort, move the T-Bar only slightly from the neutral position. The enginewill stall if the control is moved too far forward when loading the bucket.

Be sure the controls are in neutral beforestarting the engine. Operate the controls grad-

ually and smoothly. Excessive speed and quick control movementswithout regard for conditions and circumstances are hazardous andcould cause an accident.

Lift/Tilt Control

Moving the lift arm and tilting the attachment are accomplished by movement ofthe right T-Bar. To raisethe lift arm, pull the control straight rearward; to lowerthe lift arm, push the control straight forward. To tilt the attachment downward,twist the control clockwise; to tilt the attachment up or back, twist the controlcounterclockwise.

Note: The speed of the lift/tilt motion is directly proportional to the amount ofT-Bar movement and engine speed.

To place the lift arm into the detent (float) position, push the right T-Bar all theway forward into the detent. This position allows the lowered lift arm to floatwhile traveling over changing ground conditions.

Never push the lift/tilt T-Bar control into thefloat position with the attachment loaded or

raised, because this will cause the lift arm to lower rapidly.

Hand/Foot Controls

The Mustang loader may be equipped

with the hand/foot control option. Thehandles control the drive and the footpedals control the lift/tilt.

Drive Controls

Forward, reverse, speed and turningmaneuvers are controlled by movement ofthe control handles. To go forward, pushboth handles forward; for reverse, pullboth handles rearward. For turning, moveone handle farther forward or rearwardthan the other handle. Turn direction isdetermined by which handle is moved the

farthest forward; to turn left, move theright handle farther forward than the left handle. For sharp turns, move the handlesin opposite directions.

Moving the handles farther from neutral increases the speed steadily to themaximum travel speed. Tractive effort decreases as speed increases. For maximumtractive effort, move the handles only slightly from the neutral position. The enginewill stall if the controls are moved too far forward when loading the bucket.

Be sure the controls are in neutral beforestarting the engine. Operate the controls grad-

ually and smoothly. Excessive speed and quick control movementswithout regard for conditions and circumstances are hazardous andcould cause an accident.

Lift/Tilt ControlsMoving the lift arm and tilting the attachment are accomplished by movement ofthe foot pedals. The left pedal raises and lowers the lift arm; the right pedal tiltsthe attachment. To raisethe lift arm, use your heel to push down on the left pedal;to lower the lift arm, use your toes to push down on the left pedal. To tilt theattachment downward, use your toes to push down on the right pedal; to tilt theattachment upor back, use your heel to push down on the right pedal.

Note: The speed of the lift/tilt motion is directly proportional to the amount ofpedal movement and engine speed.

To place the lift arm in the detent (float) position, use your toes to push the leftpedal all the way down into the detent. This position allows the lowered lift armto float while traveling over changing ground conditions.

Never push the left pedal into the float positionwith the attachment loaded or raised, because

this will cause the lift arm to lower rapidly.

Bucket Cutting Edge

The bucket cutting edge should be replaced when it is worn to within 1 in. (25 mm)

of the bucket body.

Wheel Nuts

Wheel nut torque must be checked before initial operation and every two hoursthereafter until the wheel mounting hardware torque stabilizes at therecommended setting of 120-130 ft-lbs (161-175 Nm). When tires are removedand replaced, this procedure must be repeated.

Tires

Rear tires usually wear faster than the front ones. To keep tire wear even, rotatethe tires from front to rear and rear to front.

It is important to keep the same size tire on each side of the loader to preventexcessive wear on tires or other damage. If different sizes are used, each tire willbe turning at different speeds, causing excessive wear.

The tread bar of all tires must face the same direction.

Mounting Tires

Inflating or servicing tires can be dangerous.When possible, trained personnel should

service and mount tires. To avoid possible death or serious injury,follow the safety precautions below.

1. Be sure the rim is clean and free of rust.

2. Lubricate the tire beads and rim flanges with a soap solution. Do not use oil

or grease.3. Use a clip-on tire chuck with remote hose and gauge, allowing you to stand

clear while inflating the tire. Do not place your fingers on the tire bead or rimduring inflation.

4. Never inflate beyond 35 psi (240 kPa) to seat the beads. If the beads have notseated by the time the pressure reaches 35 psi (240 kPa), deflate the assembly,reposition the tire on the rim, lubricate both parts and re-inflate. Inflationpressure beyond 35 psi (240 kPa) with unseated beads may break the bead orrim with explosive force sufficient to cause death or serious injury.

5. After seating the beads, adjust the inflation pressure to the recommendedoperating pressure.

6. Do not weld, braze or otherwise attempt to repair and use a damaged rim.

WARNING

Battery

Before servicing the battery or electrical

system, be sure the battery disconnect switch(if equipped) is in the OFF position. If not equipped with a discon-nect switch, disconnect the ground (-) terminal from battery.

The battery on the loader is a 12-volt, wet-cell battery. To access the battery, openthe rear door and lift the engine cover.

The battery top must be kept clean. Clean it with an alkaline solution (ammoniaor baking soda and water). After foaming has stopped, flush the battery top withclean water. If the terminals and cable connection clamps are corroded or have abuild-up, disconnect the cables and clean the terminals and clamps with the samealkaline solution.

Explosive gas is produced while a battery is inuse or being charged. Keep flames or sparks

away from the battery area. ALWAYS charge the battery in a well-ventilated area.

Never lay a metal object on top of a battery, because a short circuitcan result.

Battery acid is harmful on contact with skin or fabrics. If acid spills,follow these first-aid tips:

1. Immediately remove any clothing on which acid spills.

2. If acid contacts the skin, rinse the affected area with runningwater for 10 to 15 minutes.

3. If acid contacts the eyes, flood the eyes with running water for 10to 15 minutes. See a doctor at once. Never use any medication oreye drops unless prescribed by the doctor.

4. To neutralize acid spilled on the floor, use one of the followingmixtures:

a. 1 pound (0.5 kg) of baking soda in 1 gallon (4 L) of water

b. 1 pint (0.5 L) of household ammonia in 1 gallon (4 L) of water

Whenever the battery is removed, be sure to disconnect the nega-tive (-) battery terminal connection first.
