MAINTENANCE
WARNING
Turn OFF the machine, allow all moving parts to come to a complete
stop, and disconnect the spark plug wire before moving the machine,
emptying the bag, unclogging the inlets or outlets, filling the fuel tank,
or performing maintenance and repairs.
VISUAL INSPECTION
Before and after using the chipper/shredder, closely inspect the
machine for loose parts and damage.
Check the hopper, hopper guard, and funnel for cracks, holes,
and loose bolts.
Check the box frame for cracks or damage.
Check the entire machine for loose bolts or screws.
Check the blades and hammers for cracks and dings.
Check the engine oil level.
CLEANING
Clean the machine after each use. Allow the motor to cool and remove
the spark plug wire. Brush off or vacuum wood chips and wipe off the
remaining dust from the exterior of the machine with a dry cloth.
DO NOT rinse off the chipper/ shredder with water. Remove any chips
or debris from the hopper and the discharge chute. It is much harder
to clean the machine if you allow it to sit for a while after use. You may
need to use an engine cleaner to remove the built up resins from the
motor. Engine cleaners are available at most auto parts stores.
SPARK PLUG
After every 50 hours of running the spark plug should be removed.
Check the colour of the deposits on the end of the spark plug it should
be a “tan” colour. Remove all deposits using a stiff brush a brass wire
brush is ideal. Check the spark plug gap (18.1) and adjust if required.
The correct gap should be 0.7 to 0.8mm.
ENGINE OIL
Place the machine on a level surface and warm up the engine for
several minutes. Then stop the engine.
Remove the oil filler cap.
Place an oil pan under the engine. Remove the oil drain plug so that
the oil can be completely drained. You will need to use a tube or other
similar device to prevent the oil leaking onto the frame of the chipper/
shredder.
Check the oil drain plug, gasket, oil filler cap and O-ring and if
damaged replace.
Reinstall the oil drain plug.
Add engine oil up to the upper level of the dipstick.
Air Filter
After every 100 hours of running or every month, the air filter (19.1)
should be removed, examined for deterioration and cleaned. Clean
the air filter thoroughly using environmentally friendly water based
degreasing agent. Allow to dry fully then replace the air filter.
WARNING Never run the engine without the air filter fitted.
