This machine has an oil drain hose installed on the engine to
allow for easier oil changes. Bad Boy recommends that the oil
and filter be changed at intervals of 50 usage hours or yearly,
whichever occurs first. Consult your engine owner’s
manual for exact oil capacity. Bad Boy 10W-30 synthetic
blend engine oil is recommended for maximum protection.
The fuel filter is located in the fuel line about 12˝ from
the carburetor on the side of the engine. Replace the filter
yearly. Prior to the removal of the old filter, note the
direction of fuel flow as indicated on the filter. Have towels
readily available in order to quickly remove any fuel
leakage. Always use new hose clamps and ensure the
security of the new filter by lightly pulling on each hose.
Always perform maintenance outdoors or in a well ventilated
area. Do not smoke or allow any open flames in the vicinity
of any maintenance activities.
The air cleaner is the engine’s only defense against
damaging foreign particles. It is very important that the air
cleaner element is inspected prior to each use. Remove
the element and tap its sides in order to remove debris. Do
not blow the filter out using compressed air. Doing so will
greatly reduce the air cleaner’s effectiveness. Replace
yearly; more often in dusty environments. Adhering to
these practices will help prevent loss of power and
premature engine failure.
