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.

3.1 Changing your engine oil and oil filter :

1) Remove oil fill cap and open oil drain. Allow oil to

completely drain. (Make sure to have an oil pan
ready to capture old oil and properly dispose old
oil.)

2) The oil filter is located on the right side of the

engine. Clean area around oil filter. Place a
container under the oil filter to capture any oil
and remove filter. Wipe off mounting surface and
reinstall drain plug. Torque to 10 ft*lb.

3) Place new filter in shallow pan with open end up.

Fill with new oil until oil reaches the bottom of
the threads. Allow 2 minutes for oil to be
absorbed by filter material.

4) Apply a thin film of clean oil to rubber gasket on

new filter

5) Refer to instructions on oil filter for proper

installation.

6) Fill crankcase with approximately 2 quarts of

new oil. Level should top of indicator on dipstick.

7) Reinstall oil fill/dipstick and tighten securely.
8) Start engine; check for oil leaks. Stop Engine;

correct oil leaks. Recheck oil level

9) Dispose of used oil and filter in accordance with

local ordinances.

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 and place clips back
into place and remove clamps.

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) Unlock the air cleaner cover and

remove to access the air cleaner.

2) Remove the outer and inner air

filters.

3) Replace inner and outer filter then

place the inner filter into the air intake

followed by fitting the outer filter over

the inner filter.

4) Place cap back on and close the

latches.

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

1) Remove the wire on the spark plug and

use a 5/8" socket to remove the spark plug.

2) Check the gap on 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 20ft.-lbs. Be careful not to

overtighten the spark plug.
