SILICOSIS/RESPIRATORY WARNINGS
WARNING
SILICOSIS WARNING RESPIRATORY 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.

GENERAL INFORMATION
INTENDED USE
Operate this trowel, tools and components in accordance with the manufacturer's instructions. Use of any other tools for stated operation is considered contrary to designated use. The risk of such use lies entirely with the user. The manufacturer cannot be held liable for damages as a result of misuse
TROWEL FAMILIARIZATION
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 (Figure 2) like the engine, blades, steering handle, kill switch, gearbox, etc. Check that there is always oil in the engine.
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.
Before using your trowel, test it on a flat watered down section of finished concrete that is free of any debris and other objects.
GEARBOX
The gearbox is located beneath the engine and transfers power to the spider assembly. The gearbox controls the rotational speed of the trowel and is equipped with two shafts (input and output).
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.
GUARD RING
This unit is equipped with a safety guard ring. It is designed to help protect items from coming into contact with the rotating blades while the trowel is in operation.
BLADES
The blades of the trowel finish the concrete as they are rotated around the surface. This trowel comes equipped with four combination blades (8 in./203 mm wide) per rotor equally spaced in a radial pattern and attached to a vertical rotating shaft by means of a spider assembly.
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.
ENGINE
This trowel is equipped with a SUBARU 5.7 HP gasoline engine. Refer to the engine owner’s manual for instructions regarding the operation and maintenance of your engine. Please contact your nearest Multiquip Dealer for a replacement should the original manual disappear or otherwise become unusable.
DRIVE SYSTEM
Power is transferred from the engine to the gearbox input shaft via a V-belt pulley drive system. The pulley engages using a centrifugal clutch. See parts section of this manual for a breakdown of the drive system.
CENTRIFUGAL
In the event of a trowel runaway condition (operator releases handlebars during operation), the centrifugal safety stop switch will stop the engine and bring the trowel to a halt
CAUTION
NEVER attempt to lift the trowel by yourself. ALWAYS get the assistance of another person to help lift the trowel.
SAFETY STOP SWITCH
TRAINING
For proper training, please use the “TRAINING CHECKLIST” form located in the front of this manual. This checklist will provide an outline for an experienced operator to provide training to a new operator.

DANGER
EXPLOSIVE FUEL!
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 hot! or running.
Fuel Check
1. Visually inspect to see if fuel level is low. If fuel is low, replenish with unleaded fuel.
2. When refueling, be sure to use a strainer for filtration. DO NOT top-off fuel. Wipe up any spilled fuel immediately.
V-Belt Check
A worn or damaged V-belt can adversely affect the performance of the trowel. If a V-belt is defective or worn simply replace the V-belt as outlined in the maintenance section of this manual.
Belt Guard Check
Check for damage, loose or missing hardware.
Blade Check
Check for worn or damaged blades. Check to see if one blade is worn out while the others look new. If this is the case there could be a blade pitch problem. Refer to the maintenance section of this manual for blade pitch adjustment procedure. Replace any worn blades.
WARNING
NEVER disable or disconnect the centrifugal safety
"STOP" switch. It is provided for operator safety. Injury may result if it is disabled, disconnected or improperly maintained.

INSPECTION/OPERATION
Centrifugal Safety "STOP" Switch
This trowel has been equipped with a centrifugal safety "STOP" switch (Figure 17). This switch should be tested every time the engine is started.
The switching mechanism of this switch should operate freely and should always be kept in this condition. With the switch in the OFF position, the engine should not start or run. The purpose of this switch is to stop the engine in a runaway situation, (i.e. the operator releasing the handle during operation).

NOTICE
DO NOT attempt to operate the trowel until the Safety, General Information and Inspection sections of this manual have been read and thoroughly understood.
NOTICE
The trowel is heavy and awkward to move around. Use proper heavy lifting procedures and DO NOT lift the trowel by the guard rings.
Lifting Bale
The lift bale provides an optimal lift point for lifting the trowel. When lifting the trowel onto a concrete slab, attach a chain or rope to the lifting bale. Make sure the lifting device has adequate lifting capacity to lift the trowel.
Using a crane or forklift (Figure 18) to lift the trowel is highly recommended, and is perfectly safe for the trowel. ALWAYS use extra care when lifting the trowel off the ground.
Figure 17. Centrifugal Safety "STOP" Switch
Operation
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.
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.
WARNING
NEVER attempt to lift this machine alone. NEVER lift
the trowel by the guard ring as it may rotate and cause injury.
ALWAYS make certain the handle is secure and use only the manufacturer's approved lifting point. The trowel may be lifted at the center lifting bale by crane or other lifting device of adequate capacity.

OPERATION
Maneuvering the Trowel
1. Get into the operator’s position behind the handle. With
a secure foothold and a firm grasp on the handle, slowly increase the engine speed until the desired blade speed is obtained.
2. Figure 31 below illustrates a typical walk-behind trowel application. Practice maneuvering the trowel. The trick is to let the trowel do the work.
3. 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.
