Checking the Spark Plugs
1. Look at the center of the spark plug(s) (Fig. 28).
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 r eplace 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. 28). Bend the side electrode
(Fig. 28) if the gap is not correct.

Installing the Spark Plugs
1. Install the spark plugs and metal washer. Make
sure the air gap is set correctly.
2. Tighten the spark plugs to 18/22 ft-lb
(24.4/29.8 Nm).
3. Push the wires onto the spark plugs (Fig. 27).
4. Close the hood.
Greasing and Lubrication
Service Interval/Specification
Grease the machine after every 50 operating hours or
yearly, whichever occurs first. Grease more frequently
when operating conditions are extremely dusty or
sandy.
Gr
ease T ype: General-purpose grease.
How to Grease
1. Disengage the power take off (PTO), set the
parking brake, lower the attachment lift, and turn
the ignition key to “STOP” to stop the engine.
Remove the key.
2. Clean the grease fittings with a cloth. Make sure
to scrape off any paint from 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.
Where to Add Grease
1. Lubricate the left–hand and right–hand spindles
until grease begins to ooze out of the bearings
(Fig. 29).
2. Lubricate the front axle pivot (Fig. 29).
