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 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.
Maintenance of engine
Spark Plug
After every 50 hours of running the spark plug should be removed. Check the color of the
deposits on the end of the spark plug it should be a
“Tan” color. Remove all deposits using
a stiff brush a brass wire brush is ideal. Check the spark plug gap (
Pic.18
) (18.1) and adjust
if required. The correct gap should be 0.7 to 0.8mm.
Engine oil replacement
Place the machine on a level surface and warm up the engine for several minutes. Then
stop the engine.
Remove the oil filler cap (
Pic.5
) (5.1).
Place an oil pan under the engine. Remove the oil drain plug (
Pic.5
) (5.2) 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 (
Pic.6
) (6.1).
