Maintenance & Adjustments
Maintenance
WARNING:
repairs, disengage PTO, move shift lever into neutral
position, set parking brake, stop engine and remove
key to prevent unintended starting.
Engine
Refer to the Engine Owner's Manual for engine maintenance
instructions.
Check engine oil level before each use as instructed in the Engine
Owner's Manual packed with your unit. Follow the instructions
carefully.
Changing Engine Oil
For draining oil from the engine's crankcase, proceed as follows:
1.
Run the engine for a few minutes to allow the oil in the
crankcase to warm up. Warm oil will flow more freely and
carry away more of the engine sediment which may have
settled at the bottom of the crankcase. Use care to avoid
burns from hot oil.
2.
Locate the oil drain valve on the right side of the engine
and the oil fill cap on the topside of the engine.
3.
Unscrew the oil fill cap and remove the dipstick from the oil
fill tube.
4.
Snap the small end of oil drain sleeve onto the space
provided around the oil drain plug. See Figure 6-1.
5.
Remove the oil drain plug and drain the oil into a suitable
container with a capacity of no less than 64 oz.

until fuel tank is empty.
7.
Replace the oil drain plug and tighten. Be careful not to
overtighten the oil drain plug.

Refill the engine with new motor oil as instructed in the
Engine Owner's Manual packed with your unit.
