This checklist will lists some of the minimum requirements for
machine maintenance and operation. Please feel free to detach
it and make copies. Use this checklist whenever a new operator
is to be trained or it can be used as a review for more experienced
operator’s.
Safety precautions should be followed at all times when operating
this equipment. Failure to read and understand the Safety
Messages and Operating Instructions could result in injury to
yourself and others.
HAZARD SYMBOLS
NOTE
This Owner's Manual has been developed to provide
complete instructions for the safe and efficient operation
of the MQ Whiteman C-4 FINISHER TROWEL. For
engine maintenance information, please refer to the
engine manufacturers instructions for data relative to its
safe operation.
Before using this WALK-BEHIND TROWEL, ensure
that the operating individual has read and
understands all instructions in this manual.
SAFETY MESSAGE ALERT SYMBOLS
The three (3) Safety Messages shown below will inform you
about potential hazards that could injure you or others. The
Safety Messages specifically address the level of exposure to
the operator, and are preceded by one of three words: DANGER,
WARNING, or CAUTION.
Lethal Exhaust Gases
Engine exhaust gases contain poisonous
carbon monoxide. This gas is colorless and
odorless, and can cause death if inhaled.
NEVER operate this equipment in a confined
area or enclosed structure that does not
provide ample free flow air.
Explosive Fuel
Gasoline is extremely flammable, and its
vapors can cause an explosion if ignited. DONOT start the engine near spilled fuel or
combustible fluids. DO NOT fill the fuel tank
while the engine is running or hot. DO NOT
overfill tank, since spilled fuel could ignite if it
comes into contact with hot engine parts or
sparks from the ignition system. Store fuel in
approved containers, in well-ventilated areas
and away from sparks and flames. NEVER
use fuel as a cleaning agent.
DANGER: You WILL be KILLED or
SERIOUSLY injured if you DO NOT follow
directions.
WARNING: You CAN be KILLED or
SERIOUSLY injured if you DO NOT follow
directions.
CAUTION: You CAN be injured if you
DO NOT follow directions.

7.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 replaced.
8.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

9.V-Belt Cover – Remove this cover to gain access to the Vbelt. NEVER operate the trowel with this cover removed.
10.T-Handle Release Knob – Turn this handle counterclockwise to release the upper handle and place in either
down position or operate position. Turn handle clockwise
to lock upper handle in place.
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.
DANGER
Adding fuel to the tank should be done only when
the engine is stopped and has had an opportunity to
cool down. In the event of a fuel spill, DO NOT
attempt to start the engine until the fuel residue has been completely
wiped up, and the area surrounding the engine is dry.

11.Oil Drain Plug – Remove this plug to remove oil from the
engine's crankcase.
12.Dipstick/Oil Filler Cap – Remove this cap to determine if
the engine oil is low. Add oil through this filler port as
recommended in Table 3.
Operating the engine without an air
filter, with a damaged air filter, or a
filter in need of replacement will
allow dirt to enter the engine,
causing rapid engine wear.
WARNING
Engine components can generate extreme heat.
To prevent burns, DO NOT touch these areas
while the engine is running or immediately after
operating. NEVER operate the engine with the
muffler removed.

2.If lubrication oil begins to seep out as the drain plug is
being removed, then it can be assumed that the gearbox
has a sufficient amount of oil.
3.If lubrication oil does not seep out as the drain plug is
being removed, fill with type ISO 680 (Whiteman P/N
10139) gearbox lubricant oil until the oil filler hole overflows.
Extra care should be taken when lifting the trowel off the ground.
Serious damage to the machine or personal injury could be
caused by dropping a trowel.
Even though the trowel is lightweight, always use two people
when lifting the trowel onto a slab of concrete or truck bed.
This section is intended to assist the operator with the initial

3.The best method for finishing concrete is to slowly walk
backwards (Figure 20) with the trowel, guiding the trowel
from side to side. This will cover all footprints on wet concrete.
4.Remember that if you let go of the trowel, just step away and
let the trowel come to a complete stop before trying to recover
the trowel.
Maneuvering the Trowel

If your trowel has a

start the blades turning. Adjust the blade speed after the hand
clutch is fully engaged.
Figure 20 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.
