Kohler Command Pro EFI ECV870 

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 filte:r 

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 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.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.

3)

Apply a thin film of clean oil to rubber gasket
on new filter

4)

Refer to instructions on oil filter for proper
installation.

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 failu

re.

 

3.3 Changing the air cleaner: 

1)

Unlock the air cleaner cover and remove to
access the air cleaner.

2)

Remove the air filter element.

3)

Inspect the air filter element and either
clean or replace the element.

4)

Install onto base and place cover back on
and lock into place.
