SAFETY PRECAUTIONS

Before operating this piece of equipment, the operator should read this manual.
Whenever possible, he/she should be shown how to operate the unit by an experienced
operator. It is dangerous for an inexperienced person to operate any machine. Trial and
error is not the safe way to become familiar with a piece of equipment.

To prevent injury wear the following protective clothing: Gloves, hard hat, work boots, ear
plugs, safety goggles and any other protective devices required by job conditions.

• Stay AWAY from blades during operation.

• Be cautious with the ventilation of work place. Avoid operating machine in closed

area, since engine exhaust contains poisonous gases.

• Be careful with hot components. Mufflers and other parts of the engine are hot during

operation and right after shutdown.

• Fasten fuel cap tightly and close fuel strainer cock during transportation.

BELT SETTING

STEP 1 – Loosen engine base bolt (underneath engine) to allow engine-base movement.
STEP 2 – Insert V-belt into clutch pulley and reducer pulley one at a time.
STEP 3 – Adjust the engine position by moving engine-base to ensure v-belts are tight

enough.

IMPORTANT: Normal slack should be approximately 10-15mm (1/2”) when the belts are
forcibly depressed in the middle position between rotor pulley and clutch pulley.

Tighten all engine bolts and cover V-belt and pulley with belt cover, tighten cover bolts.

PRE START-UP CHECKING

• Consult engine manual for detailed starting information.

• Check all bolts and screws for tightness. Loose bolts and screws may cause damage to

the unit.

• Make sure that all dirt, mud, etc., are thoroughly removed from areas such as cooling air

inlet of engine, carburettor, and air cleaner.

• Check V-belt tightness. The normal slack should be approximately 10-15mm (1/2”) when

the belts are forcibly depressed in the middle position between two pulleys. To set belt
tightness; refer to Belt Setting at page 3.

• Check fuel level and refill as required.

• Check engine oil level. If engine oil level is low, refill it with the correct engine oil as

stated in the engine manual.

CAUTION! – Make sure nobody is in the vicinity of the trowel when starting the engine; it
might move suddenly with force.

rope is pulled out, release the rope slowly. Do not let the rope snap back.

STEP 6 – After engine starts, open the choke halfway and warm up the engine for 2-3

minutes with low speed position. The warm up procedure should particularly be
followed during cold weather.

blades as high as possible. Sprinkle water on the floor beforehand.
