Maintenance
Checking the Spark Plug
1. Look at the center of the spark plug(s) (Fig. 13).
If you see light brown or gray on the insulator,
the engine is operating properly. A black coating
on the insulator usually means the air cleaner is
dirty.
IMPORTANT: Never clean the spark plug(s).
Always replace the spark plug(s) when it has:
a black coating, worn electrodes, an oily film,
or cracks.
2. Check the gap between the center and side
electrodes (Fig. 13). Bend the side electrode
(Fig. 13) if the gap is not correct.

the spark plug(s).
2. Tighten the spark plug(s) to 20 ft-lb (27 N.m).

Greasing and Lubrication

Grease all bearings, bushings and pivot joints every 8
operating hours. Grease more frequently when
operating conditions are extremely dusty or sandy and
immediately after every washing.
Grease Type: General-purpose grease.
How to Grease
1. Lower the loader arms and turn the ignition key
to "OFF" to stop the engine. Remove the key.
2. Clean the grease fittings with a rag. Make sure to
scrape any paint off the front of the fitting(s).
3. Connect a grease gun to the fitting. Pump grease
into the fittings until grease begins to ooze out of
the bearings.
4. Wipe up any excess grease.
Lubricating Traction Drive Chain
1. Lower the loader arms and turn the ignition key
to "OFF" to stop the engine. Remove the key.
2. Apply a general purpose oil (10W30) onto upper
and lower chain spans.
3. Start the machine and slowly move it forward to
expose un–lubed upper and lower chain spans.
4. Turn the ignition key to "OFF" to stop the
engine. Remove the key.
5. Apply oil to newly exposed un–lubed chain
spans.
