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. 

3.3 Changing the air cleaner 

1)

Locate the air filter and unbuckle the
air filter cover.

2)

Remove the cover and take out the
outer white element and the inner
blue element.

3)

Clean or replace elements.

4)

Reattach the cover making sure the

air intake is facing down.

3.4 Changing the spark plugs and checking the spark plug gap: 

1) Remove the wire on the spark plug

and use a 13/16" socket to remove

the spark plug.

2) Check the gap or the spark plug to

verify that it is 0.03 in using a feeler

gauge.

3) If the spark plug is worn, overheated,

wet, or carbon fouled replace the

spark plug.

4) Install the plug into cylinder head and

torque to 16ft-lbs. Be careful not to

overtighten the spark plug.

Vanguard 993cc

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 after the 
initial 8 hrs of use, and at intervals of 50 usage hours or 
yearly, whichever occurs first after that. The oil capacity 
is 2 quarts. 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. 

3.2 Changing your fuel filter:

1) Locate your fuel filter and mark the direction it is

facing.

2) Clamp each side of the fuel filter to minimize and

gas spills.

3) Remove the clips from each side of the fuel filter

and remove the fuel filter.

4) Place the new fuel filter in the same direction as

the old.
