HPLA/HPHA-SERIES 46"TROWEL— GENERAL INFORMATION
Blades
HPLA/HPHA-SERIES 46" Walk-Behind Trowel
Familiarization
The blades of the trowel finish the concrete as they are rotated
around the surface. Blades are classified as combination (8
inches wide), float (10 or 8 inches wide), and finish (6 inches
wide).This trowel comes equipped with either three or four
blades per rotor equally spaced in a radial pattern and
attached to vertical rotating shaft by means of a spider
assembly.
This walk-behind trowel is designed for the floating and
finishing of concrete slabs.
Take a walk around the trowel. Take notice of all the major
components (see Figure 3, pages 16 and 17) like the engine,
blades, quick pitch control, air cleaner, centrifugal stop switch
etc. Check that there is always oil in the engine.
Centrifugal Stop Switch
Read all the safety instructions carefully.Safety instructions will
be found throughout this manual and on the trowel. Keep all
safety information in good, readable condition. Operators should
be well trained on the operation and maintenance of the trowel.
In the event of a trowel runaway condition (operator releases
the handle), a centrifugal stop switch or manual clutch
depending on which trowel you have, will stop the engine
and bring the trowel to a halt.
Before using your trowel, test it on a flat watered down section of
finished concrete that is free of any debris and other objects.
CAUTION
This trial test run will increase your confidence in using the trowel
and at the same time it will familiarize you with the trowel’s
controls. In addition you will understand how the trowel handles
under actual conditions.
NEVER attempt to lift the trowel by yourself.
ALWAYS get the assistance of another
person to help lift the trowel or use a crane or
lifting device to move the trowel.
Engines
This trowel is available with an 11.0 HP HONDA gasoline engine.
Refer to the engine owner’s manual for instructions regarding
the operation and maintenance of your engine. The engine
manual is included with your trowel at the time of shipment from
Whiteman. Please contact your nearest Multiquip Dealer for a
replacement should the original manual disappear.
Moving the HPLA/HPHA-SERIES 46"Walk-BehindTrowel
This walk-behind trowel is designed to be moved and handled
in several ways.The easiest way to lift the trowel is to use the
auxiliary lifting tube that is attached to the main handle. See
page 24, Figure 20. When using the auxiliary tube, always use
two persons to lift the trowel.
Drive System
Some models have a lifting bail (option) installed. A strap or
chain can be attached to the lifting bail, allowing a forklift or
crane to lift the trowel up onto a slab of concrete. Use a lifting
device of adequate lifting capacity to lift the trowel.
Power is transferred from the engine to the gearbox input shaft
via a V-belt or pulley drive system. The pulley engages using
either a centrifugal or manual clutch. See page 23.
Gearbox
Training
The gearbox is located beneath the engine and transfers power
to the rotor or spider assembly. The gearbox controls the
rotational speed of the trowel and is equipped with two shafts
(input and output).
For proper training, please use the “TRAINING CHECKLIST”
located in the front of this manual (Page 6). This checklist will
provide an outline for an experienced operator to provide training
to a new operator.
Spider
The vertical output shaft of the gearbox connects to a cast hub
called the spider.The spider has 4 arms that extend outward
that are used for attachment of blades or other accessories.
Remember as the gearbox output shaft rotates so does the spider
assembly.

HPLA/HPHA-SERIES 46"TROWEL— CONTROLS AND COMPONENTS
(Figures 3) shows the location of the basic controls or
components, for the HPLA/HPHA-SERIES 46" trowel. Listed
below is a brief explanation of each control or component
15. Engine – This trowel uses an 11HP Honda gasoline
engine.
16. Trowel Arm – NEVER operate the trowel with a bent, broken
or out of adjustment trowel arm. If the blades show uneven
wear patterns or some blades wear out faster than others,
the trowel arm may need to be adjusted. Use the trowel
arm adjustment tool P/N 1817 to adjust the trowel arms.
1. Quick Pitch™ Control Handle – To adjust the pitch of
the blades, grasp the handle then squeeze and either move
the handle forward or backward to achieve the desired
blade pitch.
2. Handlebar Adjuster – Change the angle/height of the
handle bars by loosening star wheel, adjust handlebars to
desired location, tighten starwheel firmly to hold handlebars
in that position.
3. Hand Grip/Handle Bar – When operating the trowel, place
both hands on each grip to maneuver the trowel. Replace
hand grips when they become worn or damaged.
4. Throttle Control Lever – Controls the speed of the engine.
Pull the hand grip toward the operator to increase engine
speed (high), away from the operator to decrease engine
speed (low or idle).

Figure 5. HandleTube Installation
2. Feed the throttle cable through the cable housing.
2. On Quick-Pitch™ models, pivot the T-handle back
(full pitch) (Figure 6).This will relax the spring inside the
handle tube. On either model, spread the handle bar ends
just enough to engage the teeth on the handle tube. Attach
the hand wheel assembly, position handlebar to desired
location, and tighten hand wheel firmly.
3. Connect the throttle cable to the engine. (Figure 8). There
should be a piece of wire installed on the trowel to show

will give an incorrect perception of adjustment. Ideally, a 5 x 5"
three-quarter inch thick flat steel plate should be used for testing.
CAUTION!
ALWAYS allow the engine to
cool before servicing. NEVER
attempt any maintenance
work on a hot! engine.
1. To determine which blades need adjustment, place the
trowelinthetestarea(three-quarterinchthickplate)andlook
for the following conditions:
■
Pitch the blades as flat as possible and 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.
MAINTENANCE SCHEDULE
Daily (8-10 Hours)
1. Check the oil level in the engine crankcase and gear box,
fill as necessary.
■
Is the machine wearing out blades unevenly (i.e. one
blade is completely worn out while the others look new)?
2. CheckV-belt.
Weekly (50-60 Hours)
(Figure 41) below illustrates a "worn spider bushings or bent
trowel arms". Check to see that adjustment bolt is barely
touching (0.10" max. clearance) lower wear plate. All alignment
bolts should be spaced the same distance from the lower wear
plate.
1. Relube arms, thrust collar and clutch.
2. Replace blades if necessary.
3. Check and clean or replace the engine air filter as
necessary.
4. Replace engine oil and filter as necessary, see engine
manual.
Monthly (200-300 Hours)
1. Remove, clean, reinstall and relube the arms and thrust
collar.Adjust the blade arms.
Figure 41. Worn Spider Plate
2. Remove, clean, reinstall clutch.
Yearly (2000-2500 Hours)
(Figure 42) below illustrates the "correct alignment " for a spider
plate (as shipped from the factory).
1. Check and replace if necessary the arm bushings, thrust
collar bushings and shaft seals.
2. Check pitch control cables for wear.
3. Adjust blade speed.

blade bar to the trailing edge, combo blades should measure no
less that 3.5" (89mm). Trailing edge of blade should be straight
and parallel to the blade bar.
Blades?
Check that all blades are set at the same pitch angle as
measured at the spider. A field adjustment tool is available for
height adjustment of the trowel arms (see Optional Equipment).
Spider?
Check the spider assembly for bent trowel arms. If one of the
arms is even slightly bent, replace it immediately.
Bent trowel arms?
If trowel “bounces, rolls
concrete, or makes uneven
swirls in concrete”.
Check the trowel arm bushings for tightness. This can be done by
moving the trowel arms up and down. If there is more than 1/8"
(3.2 mm) of travel at the tip of the arm, the bushings should be
replaced. All bushings should be replaced at the same time.
Trowel arm bushings?
Check the flatness of the thrust collar by rotating it on the spider.
If it varies by more than 0.02" (0.5 mm) replace the thrust collar.
Thrust collar?
Check the thrust collar by rocking it on the spider. If it can tilt
more than 3/32" (2.4 mm) [as measured at the thrust collar O.D.],
replace the bushing in the thrust collar.
Thrust collar bushing?
Thrust bearing worn?
Check the thrust bearing to see that it is spinning free. Note:
Thrust cap, replace if necessary.
The main output shaft of the gearbox assembly should be
checked for straightness. The main shaft must run straight and
cannot be more than 0.003" (0.08 mm) out of round at the spider
attachment point.
Main shaft?
Machine has a perceptible
rolling motion while running.
Check to make sure that both fingers of the yoke press evenly on
the wear cap. Replace yoke as necessary.
Yoke?
Check to ensure that each blade is adjusted to have the same
pitch as all other blades. Adjust per maintenance section in
manual.
