4.3.3 Check Fuel Level
Be sure to use diesel fuel oil.
（Using other oil will cause low power output or damage the engine.）
Check fuel level gauge before operation. Replenish enough fuel to prevent fuel shortage during
operation.
Be sure to fasten the fuel tank cap firmly after replenishment. If fuel is spilt, wipe it up completely.
4.3.4 Check V-belt Tension
If V-belt tension too tight, it can cause shaft breakage or shorten the life of a bearing. If too loose, the
belt may slip and will cause early breakage or damage to the belt.
Adjust the fan belt and alternator V-belt by the following procedure:
(Procedures)
① Unfasten the mounting bolts of the alternator to
adjust the alternator.
② Visually check the belt for any crack, wear, and
other defect.
③ Loosen the mounting bolt of alternator once. Then
adjust it so that the belt deflection will be 8-12
mm [98.1N (10kgf)] when pressing with a finger.
④ Be careful not to leave any grease and LLC on the
belt. If any of such material is left, wipe it off
completely.
Fire prevention
Do not, under any circumstance, bring lit cigarettes and/or
matches to the fuel.
The fuel is extremely flammable and dangerous. Be careful of fire
because it is very likely to catch fire.
Refuel only after stopping the engine, and never leave open fuel
can near the machine. Do not spill. It could cause a fire. When it is
spilt, wipe it up completely.
Refilling fuel tank should be done in an outdoor well-ventilated
place.
