STH-55JD-TC — RULES FOR SAFE OPERATIONMoving the Ride-On Trowel

CAUTION

This ride-on trowel is very heavy and awkward to move around. Use proper heavy lifting procedures and DONOT attempt to lift the ride-on trowel by the guard rings.

The STH series Ride-on Power Trowel is designed to be moved and handled several ways. The easiest way to lift the ride-ontrowel is to utilize the lift loops that are welded to the frame. These lift loops are located to the left and right sides of the operator’sseat (Figure 3, Page 11).

A strap or chain can be attached to these lift loops, allowing a forklift or crane to lift the ride-on trowel up onto a slab of concrete.The strap or chain should have a minimum 2,000 pounds (1000-kg) lifting capacity and the lifting gear must be capable of liftingat least this amount.

Table 1 below defines and illustrates the various safety decals used on the ride-on trowel:

Note:See page 57 for addintional decal information.


STH-55JD-TC — SPECIFICATIONS

NOTE:

1. This value includes the seat height.

2. Sound pressure is "A" weighted . Measured at the operatorsear position while the ride-on trowel is operating at fullthrottle on concrete in a manner most often experienced in“normal” circumstances. Sound pressure may varydepending upon the condition of the concrete. Hearingprotection is always recommended.

3. The vibration level indicated is the maximum RMS (RootMean Square) value obtained at the handle grip whileoperating the ride-on trowel on curing concrete in amanner most often experienced in “normal”circumstances. Values were obtained from all three axesof motion. The values shown represent the maximumRMS value from these measurements.

4. “AW” stands for anti-wear and “MV” stands for multi-viscosity. The 68 refers to the general viscosity rangeand is similar to 10W40-engine oil (hot weather) and10W30 (cool weather).

STH-55JD-TC — GENERAL INFORMATION

STH RIDE-ON TROWEL FAMILIARIZATION

The STH series Ride-On Power Trowels are designed for thefloating and finishing of concrete slabs.

Take a walk around the STH Ride-On Power Trowel. Take noticeof all the entire major components (see Figures 2 and 3, Page11) like the engine, blades, air cleaner, ignition switch etc. Checkthat there is always oil in the engine, and hydraulic oil in thehydraulic oil reservoir.

Read all the safety instructions carefully. Safety instructions willbe found throughout this manual and on the machine. Keep allsafety information in good, readable condition. Operatorsshould be well trained on the operation and maintenance ofthe STH Ride-On Power Trowel.

Before using your STH Ride-On Power Trowel, test it on a flatwatered down section of finished concrete. This trial test runwill increase your confidence in using the trowel and at thesame time it will familiarize you with the trowel’s controls andindicators. In addition you will understand how the trowel willhandle under actual conditions.

Engine

The STH Ride-On Power Trowel is available with a standard55 HP John Deere diesel engine. Refer to the engine owner’smanual for specific instructions regarding engine operation.This manual is included with the ride-on trowel at the time ofshipping from Whiteman. Please contact your nearest MultiquipDealer for a replacement should the original manual disappear.

Blades

The blades of the ride-on power trowel finish the concrete asthey are swirled around the surface. Blades are classified ascombination (10 or 8 inches wide), finish (6 inches wide). TheSTH is equipped with six blades per rotor equally spaced in aradial pattern and attached to vertical rotating shaft by means ofa spider assembly.

Hydraulic Motor

Independent hydraulic drive motors are coupled to the engine-powered hydrostatic pumps. Each motor drives a spiderassembly.

Hydraulic Steering

Dual joystick controls located to the left and right of the operatorare provided for steering the STH-Ride on Power Trowel. Thejoysticks are linked to three hydraulic steering cylinders locatedwithin the frame of the machine. When the right side steeringjoystick is moved either forward or backward it will cause theright side of the ride-on power trowel to move in either a forwardor reverse direction. Moving the same joystick left or right causesthe trowel to move in either the left or right direction.

When the left side steering joystick is moved, it will cause the leftside of the ride-on trowel to travel in either a forward or reversedirection.

Hydraulic Pump

Delivers a continuous controlled flow of hydraulic fluid to thehydraulic motors.

3. Adjust blade speed.

4. Replace hydraulic fluid and hydraulic filters.

NOTE

After the first 200 hours, replace the hydraulic filter cartridges.

MAINTENANCE PROCEDURES

Checking/Adjusting Blade Speed

Because the two hydraulic drive motors operate independent ofeach other, the blade speed between them may vary. If the unit’ssteering is difficult to control, the blade speeds may need to bechecked, or if one spider is spinning noticeably faster or slowerthan the other, the blade speed may need to be checked. It isalso recommended that the blade speed be checked at leastonce a year.

Blade speed adjustment is a two-step process. First, the leftspider’s speed should be checked and/or adjusted. Second,the right spider’s speed should be adjusted to match the left.

Left Spider Speed Adjustment

The left spider’s speed is adjusted by changing the length ofthe rod end spacing (Figure 15) at the front of the foot pedal.Lengthening the spacing increases the blade speed; shorteningthe spacing decreases the blade speed.

STH-55JD-TC — MAINTENANCE

Right Spider Speed Adjustment

The right spider’s speed is adjusted by changing the length ofthe connecting rod on the pump actuation levers (Figure 16,). This rod is basically a turnbuckle. Rotating it in onedirection increases the length and corresponding spider speed.Rotating it the opposite direction decreases the length andspider speed. The right spider’s speed should be within 3 rpmof the left.

A good starting point in the adjustment process is to adjust therod such that both spiders begin to rotate at the same timewhen the foot pedal is slowly depressed. This will, generally,get the speeds close enough for use if instrumentation isunavailable (i.e. on the job site). From this point on, some form ofinstrumentation is required to verify that the right spider speed iswithin the tolerance specified above. A strobe or magnetic pickuptype speed indicator is recommended to verify the speeds.

The speeds should be adjusted on a dry concrete floor with theblades pitched flat. The blade speed should be set at 125-130rpm with the engine at full speed.

Matching Blade Pitch for Both Sets of Blades

Figure 15. Blade Speed Control Foot Pedal


STH-55JD-TC — MAINTENANCE

Sometimes it may be necessary to match blade pitch betweenthe two sets of blades. There are some signs that this may benecessary. For example, the differences in pitch could cause anoticeable difference in finish quality between the two sets ofblades. Or, the difference in blade pitch could make themachine difficult to control. This is due to the surface area incontact with the concrete (the blade set with the greater contactarea tends to stick to the concrete more).

Twin Pitch

Trowel blade pitch is controlled by rocker switches located onthe top of the left and right joystick handles. The rocker switch onthe left handle pitches only the left side blades. The rocker switchon the right handle pitches blades on both the left and rightsides.

The left side rocker switch is used to "match" blade pitch of theleft and right sides. Once the two sides are "matched" (all bladeson both sides are completely flat), the right side rocker switchmay be used to pitch both sides simultaneously (Twin Pitch).

Important: just as with mechanical Twin Pitch, when using theright side switch, if the blades on either side reach the maximumor minimum pitch condition, both sides will stop pitching.

If the pitch angle is significantly different between the left andright side blades, they must be "matched" (blades), using the leftside rocker switch. Always remember to use the left side rockerswitch first when matching the left and right blades. After both leftand right side blades have been matched then the right siderocker switch (Twin Pitch) can be used.

Blade Pitch Adjustment Procedure

The maintenance adjustment of blade pitch is an adjustmentthat is made by a bolt (Figure 17) on the arm of the trowel bladefinger. This bolt is the contact point of the trowel arm to the lowerwear plate on the thrust collar. The goal of adjustment is to promoteconsistent blade pitch and finishing quality.

There are some things to look for when checking to see ifadjustment is necessary. Is the machine wearing out bladesunevenly (i.e. one blade is completely worn out while the otherslook new)? Does the machine have a perceptible rolling orbouncing motion when in use? Look at the machine while it isrunning, do the guard rings “rock up and down” relative to theground? Do the pitch control cylinders rock back and forth? Theseare some of the indications that the blade pitch may need to beadjusted using the adjustment bolts on the trowel blade finger.

The easiest and most consistent way to make this adjustment isto use the Trowel Arm Adjustment Fixture (P.N. 9177) . This fixturewill allow consistent adjustment of the trowel arm fingers. It comeswith all the hardware necessary to properly accomplish thismaintenance and instructions on how to properly utilize this tool.Adjusting the trowel arm fingers without a fixture requires a specialtalent.

If a trowel arm adjustment fixture is not available and immediateadjustment is necessary; we suggest the following procedure.If you can see or feel which blade is pulling harder, adjust thebolt that corresponds to that blade. Another way to determinewhich blades need adjustment is to place the machine on aflat surface and pitch the blades as flat as possible. Now, look atthe adjustment bolts. They should all barely make contact withthe lower wear plate on the spider. If you can see that one ofthem is not making contact; some adjustment will be necessary.

Figure 17. Blade Pitch Adjustment Bolt


STH-55JD-TC — MAINTENANCEIt will be possible to adjust the “high” bolts down to the level ofthe one that is not touching, or adjust the “low” bolt up to thelevel of the higher ones. If possible, adjust the low bolt up to thelevel of the rest of the bolts. This is the fastest way, but may notalways work. Verify that after adjustment, the blades pitchcorrectly. Often times, if the blades are incorrectly adjusted, theywill not be able to pitch flat. This occurs when the adjustingbolts have been raised too high. Conversely, sometimes theadjusting bolts are too low and the blades cannot be pitchedhigh enough for finishing operations.

Changing A Blade

Whiteman recommends that all the blades on the entire machinebe changed at the same time. If only one or some of the bladesare changed at one time, the machine will not finish concreteconsistently and the machine may wobble or bounce.

1. Place the machine on a flat, level surface. Adjust the bladepitch control to make the blades as flat as possible. Notethe blade orientation on the trowel arm. This is importantfor ride-on trowels as the two sets of blades counter-rotate.Lift the machine up, placing blocks under the main guardring to support it.

2. Remove the bolts and lock washers on the trowel arm,and then remove the blade.

3. Scrape all concrete and debris from the trowel arm. Thisis important to properly seat the new blade.

4. Install the new blade, maintaining the proper orientationfor direction of rotation.

5. Affix the bolts and lock washers.

6. Repeat steps 2-5 for all remaining blades.

Checking Hydraulic Pressure

It should be mentioned that most hydraulic problems are aresult of low fluid levels. Before checking any other possibilities,make sure the hydraulic fluid level is half way up the sight glasswhich is located at the right end of the frame.

Hydrostatic pressure can be checked using a pressure gauge(Figure 18) with a range of at least 5,000 psi. It is best to use twogauges simultaneously, but it is possible to use only one gaugeand repeat the procedure for each side.

To fully test the hydrostatic system, the spiders will need to belocked so that they cannot rotate. This can easily be done bywrapping a chain around an arm on each spider, thus chainingthem together in the back of the trowel.

Once the pressure gauges are installed and the spiders chainedtogether, the system can be checked.

With the engine at 50% to 70% of full speed, and spiders chainedtogether, slowly depress the foot pedal and read the gauges.The hydrostatic pressure should get to at least 3,200 psi. If thehydrostatic pressure will not attain 3,200 psi, the pump shouldbe inspected and/or serviced by an authorized servicerepresentative.

Checking Charge Pressure

With the foot pedal in the idle position and the engine at fullspeed, the pressure should be about 200 psi. This pressure isreferred to as "Charge Pressure". Charge pressure can bechecked more accurately using a 300 psi pressure gaugeattached to the charge pressure diagnostic coupler. See Figure18.

If the charge pressure is less than 150 psi, the charge systemmay need to be inspected and/ or serviced. In particular, thesuction filter and charge pump relief valve should be checked.The suction filter may be plugged, or the relief valve may bestuck. Either condition may cause low charge pressure.

For STH troubleshooting hints see Table 3 on preceeding page.
