Engine Maintenance
Servicing the Air Cleaner
Note:
Service the air cleaner more frequently (every few
hours) if operating conditions are extremely dusty or sandy.
Removing the Element
1.
Park the machine on a level surface and disengage the
blade control (PTO).
2.
Move the motion control levers to the brake position,
stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
3.
Clean around the air cleaner cover to prevent dirt from
getting into the engine and causing damage. Lift the
cover and remove the hose clamp securing the air
cleaner assembly to the engine ().
4.
Loosen the hose clamp and remove the paper element
().

Cleaning the Element
Service Interval:
Every 100 hours—Service the paper
element. (more often in dusty, dirty
conditions)
Every 200 hours/Yearly (whichever comes
first)—Replace the paper element. (more often in
dusty, dirty conditions)
1.
Lightly tap the element on a flat surface to remove dust
and dirt.
2.
Inspect the element for tears, an oily film, and damage
to the seal.
Important:
Never clean the paper element with
pressurized air or liquids, such as solvent, gas,
or kerosene. Replace the paper element if it is
damaged or cannot be cleaned thoroughly.

Note:
Using multi grade oils (5W-20, 10W-30, and 10W-40)
will increase oil consumption. Check oil level more frequently
when using them.
Checking the Engine Oil Level
Service Interval:
Before each use or daily
Note:
Check the oil when the engine is cold.
WARNING
Contact with hot surfaces may cause personal
injury.
Keep hands, feet, face, clothing and other body
parts away the muffler and other hot surfaces.
Important:
Do not overfill the crankcase with oil
because damage to the engine may result. Do not run
engine with oil below the low mark because the engine
may be damaged.
1.
Park the machine on a level surface, disengage the
blade control switch, stop the engine, engage parking
brake, and remove the key.
2.
Make sure the engine is stopped, level, and is cool so
the oil has had time to drain into the sump.
3.
To keep dirt, grass clippings, etc., out of the engine,
clean the area around the oil fill cap/dipstick before
removing it.
