NSPECTION
Before and after every use of the wood chipper, it is recommended that the following inspection
process take place. This is quick and easy, and ensures your safety as well as the machine’s
performance.
1.
Check the Hopper, Chute, Funnel and guards for cracks, holes and loose bolts;
2.
Check the frame and base of the machine for cracks or damage;
3.
Check all the bolts and screws to ensure tightness;
4.
Wear gloves, check the blades are not cracked or loose;
5.
Check the engine oil level using a dipstick.
8.2.C
LEANING
It is strongly recommended to clean the machine after every use. After use, turn off the machine,
allow the engine to cool fully, and remove the spark plug.
Brush off or vacuum excess wood chippings and wipe off the remaining dust from the exterior of
the machine with a dry cloth. Do not expose the machine to water or attempt to clean by
pouring water on/into it. Remove any chips or debris from the hopper and the discharge chute.
It is increasingly difficult to clean this machine
the longer you let it sit unclean. The machine’s
performance will naturally decrease if it is not properly cared for.
To clean the engine from built-up resins, you may need to purchase an engine cleaner. These are
available at most auto-parts stores or online.
