HTX-SERIES — SILICOSIS/RESPIRATORY WARNINGS
WARNING
SILICOSIS WARNINGRESPIRATORY 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.

1.When checking or adding oil, place the machine so the
engine is level.
2.Pull the engine oil dipstick from its holder, (item 1, Fig 7).
3.Determine if engine oil is low, (item 4). Oil should be
between the upper limit and lower limit (add oil) lines.
4.If oil is below the "Add Engine Oil" line add oil up to upper

make its way to the oil pan before rechecking.
DO NOT overfill the oil pan with engine oil. Always keep the
engine oil level between the upper and lower limit lines on
the dipstick.
Hydraulic Oil
Determine if the hydraulic oil is low by observing the level of oil
in the hydraulic Oil Sight Glass, (Figure 8). The hydraulic tank
has an elevated overflow bottle. DO NOT remove the fill cap
when the oil is hot or spillage will occur.
ALWAYS allow hydraulic oil to cool
before removing fill cap.
CAUTIONCAUTION

Steering
Two joysticks (Figures 14 and 15) located to the left and right of
the operator’s seat provide directional control for the HTXSERIES Ride-On Power Trowel. Table 3 illustrates the various
directional positions of the joysticks and their effect on the rideon trowel.
See Table 3 for steering and directional relationship to Joystick
Control movement.
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.

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.

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.

Right Side Trowel Speed Adjustment
The right side trowel speed is adjusted by changing the length

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.
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.

It is recommended that all the blades on the entire machine are
changed at the same time. If only one or some of the blades are

pressure will not attain 3,625 psi (250 bar), the pump should be
inspected and/or serviced by an authorized service
representative.
Steering pressure is also checked at either of the high pressure
(Table 5) indicates proper steering pressure. Check with engine

diagnostic couplers under the right grill guard. Check steering
pressure at either coupler with a 300-600 PSI gauge.
CAUTIONCAUTION
CAUTION
CAUTIONCAUTION
DO NOT depress the FOOT PEDAL with the 300-600 PSI
gauge installed or the gauge will be ruined.
Run the engine at full RPM. The steering system's factory setting
is as shown in Table 5, however some operators may prefer a
more responsive steering (higher pressure required) and some
operators may prefer a "softer feel" (lower pressure required).
Steering Pressure Adjustment
Remember, DO NOT depress the foot pedal with the 300-600
PSI gauge installed. Immediate damage to the gauge will occur.
1.Remove right grill guard.
2.Install 300 or 600 PSI gauge (Figure 43).
3.Loosen 1-1/16" jam nut on charge relief valve (Item A,
Figure 44).

4.Use a 1/2" socket to adjust the small hex nut within the
larger hex jam nut (Item B, Figure 44).
5.Adjust to proper steering pressure specifications shown in
Table 5.
6.Retighten jam nut, remove gauge, and reinstall grill guard.
Access the pitch block and pitch pressure test port at the rightrear of the trowel, (Figure 45). Removal of the right-rear seat
frame panel may be necessary. Pitch pressure must be measured
with a pitch switch
activated
. With pitch switches unactivated,
the pitch pressure will be the same as the charge/steering
pressure. Proper pitch pressure is 2300 PSI (2250 - 2350 PSI).
Pitch Pressure Out of Specification
If the pitch pressure check is out of specification, check for the
following:
1. Correct hydraulic fluid level.
2. Plugged hydraulic oil filter
3. Loose or leaking fittings.
4. Ruptured/damaged hydraulic lines.
5. Faulty hydraulic pump.
6. Pitch Pressure Relief Valve no longer at factory setting.
The Pitch Pressure Relief Valve is SET AT THE FACTORY, and
normally should not require adjustment. If all other systems are
found not to be defective and the pitch relief valve is suspect, the
following steps can be used to adjust the valve.
NEVER allow the pitch pressure to exceed 2700 PSI or
equipment damage may result.

earlier. (See Pitch Pressure Check)
5.If pressure requires further adjustment, shut the engine
down and repeat steps 2 through 4 until pressure check
reads 2300 PSI.
Installing Pans Onto Finisher Blades1.Lift trowel just enough to slide pan under blades. Lower
These round discs sometimes referred to as "pans" attach to the
spiders arms and allow early floating on wet concrete and easy
movement from wet to dry areas. They are also very effective in
embedding large aggregates and surface hardeners.
WARNINGWARNING

ALWAYS install pans either on the work area or on an area
that is next to and level with the work area. DO NOT lift the
trowel when the pans are attached.
Refer to Figure 48 when installing pans onto finisher blades.

(Item #4).
2.Rotate blades into position under Z-Clips. Ensure that the
blades are rotated in the direction of travel when the machine
is in operation or use the engine to rotate the blades into
position.
3.Attach the blade tie-downs (Item #3) to the far side of the ZClip brackets (Item #4) with tie-down knobs (Item #2) as
shown in Figure 48.
4.Check to make certain that the blade edges are secured
under the Z-Clips and the tie-downs are secured completely
over the edges of the blade bar before the machine is put back
into operation.
