C-4 FINISHER TROWEL— SAFETY MESSAGE ALERT SYMBOLS
FOR YOUR SAFETY AND THE SAFETY OF OTHERS!
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,

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. DO NOT 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

C-4 FINISHER TROWEL— BASIC ENGINE
Figure 4. Engine Controls and Components
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.
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.
2. Fuel Tank – Holds unleaded gasoline. For additional
information refer to engine owner's manual.

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.
8. Choke Lever – Used in the starting of a cold engine, or in cold weather conditions. The choke enriches the fuel mixture.
NOTE
9. Spark Plug – Provides spark to the ignition system. Set spark plug gap to 0.6 - 0.7 mm (0.028 - 0.031 inch) Clean spark plug once a week.
10. Muffler – Used to reduce noise and emissions.
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.

Motor fuels are highly flammable and can be dangerous if mishandled. DO NOT smoke while refueling. DO NOT attempt to refuel the trowel if the engine is
1. Remove the gasoline cap located on top of fuel tank.
2. Visually inspect to see if fuel level is low. If fuel is low, replenish with unleaded fuel.

C-4 FINISHER TROWEL — INITIAL START-UP
Lifting the Trowel Onto a Slab.
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 start-up of the walk-behind trowel. It is extremely important that this section be read carefully before attempting to use the trowel in the field.
DO NOT use your trowel until this section is thoroughly understood

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.

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.

Blades are a vital part of finishing concrete. This Whiteman finisher has been designed to finish concrete and is 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.
