MAINTENANCE and LUBRICATION
DANGER: NEVER run engine inside building or enclosed area. Exhaust gases contain
carbon monoxide, an odorless and deadly poison.
Engines are shipped without oil or gasoline. Refer to MANUFACTURER'S INSTRUCTIONS for
proper procedures and recommended fluids.
IMPORTANT DO NOT drop the machine off the back of a vehicle, this may cause damage
to the body and frame. Machines should always be lifted, ramped or by a trailer.
LUBRICATING INSTRUCTIONS:
CHECK crankcase and gearbox oil level before each use.
CHANGE crankcase and gearbox oil as recommended by the manufacturer's instructions.
ADD grease to the pillow block bearings after every 100 hours of use.
CLEAN vertical frame posts and sleeves frequently to prevent binding. Do not use oil base lubri-
cants or grease. Silicone is recommended.
SHUT OFF ENGINE and disconnect spark plug wire to adjust, service, refuel or clean the
machine. Accidental engine starting is possible by rotating the cutter wheel.
ALL nuts, fasteners and fittings must be kept properly torqued. After every 25 hours of use the
engine nuts and bolts should be checked and tightened, if necessary. Add lock-tight to bolt threads.
FILTERS:
The air filter needs to be cleaned every 10 hours. More often in dusty dry conditions: Check engine
owners manual for further instructions.
Attach a remote air filter with pre-cleaner in serious dusty conditions, this will add to the engine life
considerably.
CLUTCH:
The slip clutch facings should be changed if the thickness is worn to 1/16" or less, this will maintain
the fast digging speed this type of unit can perform. Check every 20-25 hours of use.
ADJUSTMENT: Shoulder bolts must be kept tight. If the clutch wears to the point where
stopping the blades will not stall the engine within a few revolutions, tension
should be increased by adding a washer under each should bolt, or by
replacing the clutch facings.
