connect the positive (red) cable to the positive (+)
battery post (Fig. 3). Slide the rubber cover over the
battery post.
Warning
Incorrect battery cable routing could damage the
traction unit and cables, causing sparks. Sparks
can cause the battery gasses to explode, resulting
in personal injury.
Always disconnect the negative (black) battery
cable before disconnecting the positive (red)
cable.
Always connect the positive (red) battery cable
before connecting the negative (black) cable.
8. Using the bolt and wing nut supplied with the battery,
connect the negative (black) cable to the negative (–)
battery post (Fig. 3).
Note: Ensure that the battery cables do not contact any
sharp edges or each other.

Servicing the Spark Plugs

Check the spark plugs after every 200 operating hours.
Ensure that the air gap between the center and side
electrodes is correct before installing each spark plug. Use
a spark plug wrench for removing and installing the spark
plugs and a gapping tool/feeler gauge to check and adjust
the air gap. Install new spark plugs if necessary.
Type: Champion Premium Gold 2071 or Champion
RC12YC (or equivalent) Air Gap: 0.030 in. (0.76 mm)

Checking the Spark Plugs
1. Look at the center of the spark plugs (Fig. 29). 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 plugs. Always
replace the spark plugs when they have a black coating,
worn electrodes, an oily film, or cracks.
2. Check the gap between the center and side electrodes
(Fig. 29).
3. Bend the side electrode (Fig. 29) if the gap is not
correct.
