HTX-SERIES — PROPOSITION 65 WARNING

Engine exhaust and some of its constituents, and some dust created by power sanding, sawing, grinding, drillingandotherconstructionactivities contains chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. Some examples of these chemicals are:

Leadfromlead-basedpaints. Crystallinesilicafrombricks. Cementandothermasonryproducts. Arsenicandchromiumfrom chemically treatedlumber.

Your risk from these exposures varies, dependingonhowoftenyoudothistype of work. To reduce your exposure to these chemicals: work in aALWAYS well ventilated area, and work with

approved safety equipment, such as

dust masks that are specially designed to filter out microscopic particles.

HTX-SERIES — SILICOSIS/RESPIRATORY WARNINGS

WARNING

SILICOSIS WARNING RESPIRATORY HAZARDS

Grinding/cutting/drilling of masonry, concrete, metal and other materials with silica in their composition may give off dust or mists containing crystalline silica. Silica is a basic component of sand, quartz, brick clay, granite and numerous other minerals and rocks. Repeated and/or substantial inhalation of airborne crystalline silica can cause serious or fatal respiratory diseases, including silicosis. In addition, California and some other authorities have listed respirable crystalline silica as a substance known to cause cancer. When cutting such materials, always follow the respiratory precautions mentioned above.

WARNING

Grinding/cutting/drilling of masonry, concrete, metal and other materials can generate dust, mists and fumes containing chemicals known to cause serious or fatal injury or illness, such as respiratory disease, cancer, birth defects or other reproductive harm. If you are unfamiliar with the risks associated with the particular process and/or material being cut or the composition of the tool being used, review the material safety data sheet and/or consult your employer, the material manufacturer/supplier, governmental agencies such as OSHA and NIOSH and other sources on hazardous materials. California and some other authorities, for instance, have published lists of substances known to cause cancer, reproductive toxicity, or other harmful effects.

Control dust, mist and fumes at the source where possible. In this regard use good work practices and follow the recommendations of the manufacturers or suppliers, OSHA/NIOSH, and occupational and trade associations. Water should be used for dust suppression when wet cutting is feasible. When the hazards from inhalation of dust, mists and fumes cannot be eliminated, the operator and any bystanders should always wear a respirator approved by NIOSH/MSHA for the materials being used.

HTX-SERIES — OPERATION

1. The foot pedal, (Figure 16) solely controls blade speed. The position of the foot pedal determines the blade speed. Slow blade speed is obtained by slightly depressing the pedal. Maximum blade speed is obtained by fully depressing the pedal.

5. Practice maneuvering the Ride-on Power Trowel using the information listed in Table 3. Try to practice controlled motions as if you were finishing a slab of concrete. Practice edging and covering a large area

6. Try adjusting the pitch of the blades. This can be done with the ride-on trowel stopped or while the trowel is moving, whatever feels comfortable. Test the operation of optional equipment like retardant spray and lights if equipped.

7. Pull both the left and right joysticks backward, (Figure 18) and repeat steps 3 through 6 while substituting the word reverse for forward.

2. Right Joystick Control

3. Push Forward

Figure 17. Joystick Control Forward Direction

3. With your right foot, slowly depress the right foot pedal halfway. Notice that the ride-on power trowel begins to move in a forward direction. Release both joystick controls to stop forward movement then remove your right foot from the foot pedal.

4. Practice holding the machine in one place as you increase blade speed. When about 75% of maximum blade speed has been reached, the blade will be moving at proper finishing speed. The machine may be difficult to keep in one place. Trying to keep the ride-on trowel stationary is a good practice for operation.

Trowel Speed Limiter Control

The speed limiter control located on the control panel, (Figure

19) can be used to adjust the maximum trowel speed that can be obtained when the foot pedal is fully depressed. Pull up to reduce the maximum speed and push down to return to full speed. For fine adjustments, rotate the knob clockwise or counterclockwise.

MAINTENANCE PROCEDURES

Checking/Adjusting Trowel Speed

Because the two hydraulic drive motors operate independent of each other, the trowel speed between them may vary. If the unit’s steering is difficult to control, or if one spider is spinning noticeably faster or slower than the other, the trowel speed may need to be checked. It is also recommended that the trowel speed be checked at least once a year.

Trowel speed adjustment is a two-step process. First, the left side should be checked and/or adjusted. Second, the right side should be adjusted to match the left.

Left Side Trowel Speed Adjustment

The left side trowel speed is adjusted by the set bolt located under the operator's platform, (Item A, Figure 27) and accessed by opening the storage panel door. Backing the set screw out decreases the left side trowel speed; screwing it inward increases the speed.

Figure 28. Pump Connecting Rod & Levers

This rod is basically a turnbuckle, (Figure 29). Rotating it in one direction increases the length and corresponding trowel speed. Rotating it the opposite direction decreases the length and trowel speed. The right side trowel speed should be within 3 rpm of the left.

1. Pump Actuation Levers

2. Connecting Rod

Figure 27. Trowel Speed Control

Right Side Trowel Speed Adjustment

The right side trowel speed is adjusted by changing the length of the connecting rod on the pump actuation levers, (Figure 28).

Figure 29. Turnbuckle & Adjustment Nuts

A good starting point in the adjustment process is to adjust the rod such that both trowels begin to rotate at the same time when the foot pedal is slowly depressed. This will, generally, get the speeds fairly close; close enough for use if instrumentation is unavailable (i.e. on the job site). From this point on, some form of instrumentation is required to verify that the trowel speeds are within tolerance. A strobe or magnetic pickup type speed indicator is recommended to verify the speeds.

The trowel speeds should be adjusted on a dry concrete floor with the blades pitched flat. Units with the Kubota turbocharged engine should be set at 140-160 RPM with the engine at full speed.

Matching Blade Pitch for Both Sets of Blades

Sometimes it may be necessary to match blade pitch between

the left and right sets of blades. There are some signs that this may be necessary. For example, the differences in pitch can cause a noticeable difference in finish quality between the left and right sets of blades. The difference in blade pitch can also make the machine difficult to control. This is due to the surface area in contact with the concrete, (the blade set with the greater contact area tends to stick to the concrete more).

To synchronize pitch on both sides, the left blade assembly can be pitched by itself. By using the electric blade pitch rocker switches, (Figure 30) the pitch can be syncronized on the left and the right sides.

The easiest and most consistent way to make this adjustment is to use the Trowel Arm Adjustment Fixture (P.N. 9177) that is manufactured by Whiteman Industries. This fixture will allow consistent adjustment of the trowel arm fingers. It comes with all the hardware necessary to properly accomplish this maintenance and instructions on how to properly utilize this tool. Adjusting the

Blade Pitch Adjustment Procedure

The maintenance adjustment of blade pitch is an adjustment that is made by a bolt, (Figure 31) on the arm of the trowel blade finger. This bolt is the contact point of the trowel arm to the lower wear plate on the thrust collar. The goal of adjustment is to promote consistent blade pitch and finishing quality.

Watch for the following indications when determining if blade pitch adjustments are necessary:

trowel arm fingers without a fixture requires a special talent. If a trowel arm adjustment fixture is not available and immediate

adjustment is necessary; we suggest the following procedure. If you can see or feel which blade is pulling harder, adjust the bolt that corresponds to that blade. Another way to determine which blades need adjustment is to place the machine on a flat surface and pitch the blades as flat as possible. Now, look at the adjustment bolts. They should all barely make contact with the lower wear plate on the spider. If you can see that one of them is not making contact; some adjustment will be necessary.

■

Is the machine wearing out blades unevenly, (i.e. one blade is completely worn out while the others look new)?

■

Does the machine have a perceptible rolling or bouncing motion when in use?

■

Look at the machine while it is running, do the guard rings “rock up and down” relative to the ground?

It will be possible to adjust the “high” bolts down to the level of the one that is not touching, or adjust the “low” bolt up to the level of the higher ones. If possible, adjust the low bolt up to the level of the rest of the bolts. This is the fastest way, but may not always work. Verify that after adjustment, the blades pitch correctly. Often times, if the blades are incorrectly adjusted, they will not be able to pitch flat. This occurs when the adjusting bolts have been raised too high. Conversely, sometimes the adjusting bolts are too low and the blades cannot be pitched high enough for finishing operations.

4. Examine the 2-piece bronze trowel arm bushing insert (Figure 34), clean if necessary. Replace bushing if out-of-round or worn.

Checking Trowel Arm Straightness

Trowel arms can be damaged by rough handling, (such as dropping the trowel on the pad), or by striking exposed plumbing, forms, or rebar while in operation. A bent trowel arm will not allow the trowel to operate in a smooth fluid rotation. If bent trowel arms are suspect, check for flatness as follows, refer to Figures 35 and 36:
