SECTION 2: DRIVE BELT

Shown on the right is the tensioner for your pump 
belt. Adjusting this will either increase or decrease 
tension on the belt. Use a ¾” wrench to loosen the 
jam nuts and either tighten for more belt tension or 
loosen for less belt tension. 

The belt tension should be set between 60-65 
lbs.  

Use a belt tension gauge to ensure the proper 
tension. Your dealer or service center will have a 
belt tension gauge or you can buy one (Part Number 
041-9999-00).

When adjusting the tracking on the mower, the 

length of the pushrods can be changed by 

screwing the swivel joint in or out on the ends of 

the rods.  Shortening the overall length of the rod 

slows the pump down.  Lengthening the rod will 

increase the speed of the pump.

SECTION 3: ENGINE

810cc Vanguard

 

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 dipstick and open oil drain. Allow

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

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 one and replace the clips back into

position 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.
