safety information in good, readable condition. Operators should
be well trained on the operation and maintenance of the trowel.
Before using your trowel, test it on a flat watered down section of
finished concrete that is free of any debris and other objects.
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.
Engines
This trowel is available with either an 8.0 HP HONDA, 8.5 HP
ROBIN, or a 8.0 HP Briggs and Stratton gasoline engine. In
addition, a 2.0 horsepower 115/230 VAC, single phase electric
motor is also available. 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 shipping from Whiteman. Please contact your nearest
Multiquip Dealer for a replacement should the original manual
disappear.

a 2 HP, 115/230 VAC single phase electric motor.
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.
17. Blades – This trowel is equipped with combination blades.
These blades are versatile and should take care of most
troweling needs. In addition float discs can be attached to
the trowel arms that will allow the trowel to float on "wet"
concrete.
18. V-Belt Cover – Remove this cover to gain access to the Vbelt. NEVER operate the trowel with this cover removed.
19. Weights – The trowel may be equipped with two 10 lbs.
weights. The weights may be removed to reduce the
operating weight of the trowel.

INITIAL SERVICING
The engine (Figure 4) must be checked for proper lubrication and
filled with fuel prior to operation. Refer to the manufacturers engine
manual for instructions & details of operation and servicing. The
engine shown above is a HONDA engine, operation for other
types of engines may vary somewhat.
1. Fuel Filler Cap – Remove this cap to add unleaded
gasoline to the fuel tank. Make sure cap is tightened
securely. DO NOT over fill.
5. Fuel Valve Lever – OPEN to let fuel flow, CLOSE to stop
the flow of fuel.
6. Choke Lever – Used in the starting of a cold engine, or in
cold weather conditions. The choke enriches the fuel
mixture.
7. Air Cleaner – Prevents dirt and other debris from entering
the fuel system. Remove wing-nut on top of air filter
cannister to gain access to filter element.
DANGER
Adding fuel to the tank should be done only when
the engine is stopped and has had an opportunity to

Figure 31 below illustrates a typical walk-behind trowel
application. Practice maneuvering the trowel. The trick is to let
the trowel do the work.
Continue to practice maneuvering the trowel. Try to practice as if
you were finishing a slab of concrete. Practice edging and
covering a large area. Remember a good finishing technique is
to work backwards. Be careful when moving backwards so that
hazards can be avoided. The best way to get accustomed to the
trowel is repeated use.

Blades are a vital part of finishing concrete. This Whiteman
finisher has been designed to finish concrete and are built to
stringent quality standards out of the finest trowel steel. If you need
replacement blades, consult your parts list in this manual for part
numbers and order them from your Multiquip parts dealer or
importer.
Combo Blades
This trowel was equipped with combination FLOAT/FINISH
(Figure 32) blades as original equipment. These blades have
been designed for optimum performance in both the floating and
finishing operations. These blades are versatile and should take
care of most troweling needs.
Clip-On Float Blades (Optional)
These blades will clip (Figure 34) on to an existing installed
blade, allowing your finisher to float on “wet” concrete so that the
troweling operation can begin as early as possible. They are
easily removable, so that after the floating operation, when the
concrete is sufficiently cured, they can be removed to expose the
finish blades for continued troweling.
Float Discs (Optional)
These round discs (Figure 35) attach to the spiders and allow the
machine to “float” on “wet” concrete. The disc design allows early
floating and easy movement from wet to dry areas. They are also
very effective in embedding large aggregates and surface
hardeners.
Figure 34. Clip-On Float Blade
Figure 32. Combination Blade
Finish Blades (Optional)
These blades (Figure 33) have been specifically designed for
finish operations with this trowel. They will provide a premium
surface finishing capability from your trowel. They should only be
used after the concrete has set to the point where the trowel does
not sink into the concrete when placed on it.

Grinding Attachments
Available grinding attachments are used for grinding surface
imperfections or joints. These attachments allow greater utilization
of your trowel. Figure 36 illustrates a typical grinding disk assembly,
complete with hub and stone mounting plate.
Trowel Arm Adjustment Tool
If blades show uneven wear patterns or some tend to wear out
faster than others, the trowel arms may need to be adjusted.
Whiteman makes a special tool (Figure 38) that will adjust all of
the trowel arms consistently. The Trowel Arm Fixture P/N is 1817.
Figure 36. Grinding Disk
Lifting Bale
There is a heavy duty, center balance type lifting bale (Figure 37)
made specifically for your trowel. These bales are ideal for lifting
and transporting your trowel. They are designed to lift the finisher
and balance it on it’s center of gravity, providing great stability
while lifting. This option is not available on electric trowel models.
