SPARK PLUG

The spark plug(s) should be inspected at the regular
intervals specified in the engine manufacturer's owner's
manual and cleaned or replaced as required.
Dirty, worn, or fouled spark plugs may cause hard start-
ing, rough engine operation, or loss of power, and may
contribute to premature starter failure from excessive
cranking of the engine.
The spark plug(s) can be found by looking for the thick
black spark plug cable(s) at the engine head, and remov-
ing the spark plug boot(s) that connect(s) the cable to the
spark plug.
The spark plug boot can be removed from the spark plug
by pulling the boot away from the spark plug with a slight
side-to-side motion.
To remove the spark plug(s) from the engine for inspec-
tion or replacement:
1. Turn the ignition off and remove the key. Allow
engine to cool.
2. Raise the hood.
3. Locate the spark plug cable and boot, and pull the
boot off the spark plug.
4. Using a spark plug socket and socket wrench or
equivalent spark plug removal tool, unscrew the
spark plug from the engine by turning the spark plug
counter-clockwise.
5. Inspect the spark plug in accordance with the engine
manufacturer's instructions, and clean, re-gap, or
replace the spark plug as required.
6. When reinstalling the spark plug, start the plug into
the engine by first turning it clockwise by hand to pre-
vent cross-threading and possible damage to the
spark plug port. Tighten as instructed in engine man-
ufacturer's manual.

BATTERY MAINTENANCE

Be careful when handling the battery. Avoid
spilling electrolyte. Keep flames and sparks
away from the battery.
When removing or installing battery cables, dis-
connect the negative cable FIRST and reconnect
it LAST. If not done in this order, the positive ter-
minal can be shorted to the frame by a tool.
Checking the Battery Fluid
1. Raise the hood.
2. Remove battery filler cap. Fluid must be even with split
ring full mark. If not, add distilled water.
3. Reinstall filler cap.
Cleaning the Battery and Cables
1. Disconnect the cables from the battery, negative
cable first (B, Figure 2).
2. Remove the holddown strap (D), then remove the
battery.
3. Scrub the battery, cables and battery compartment
with baking soda and water.
4. Clean the battery terminals and cable clamps with a
wire brush and battery post terminal cleaner.
5. Reinstall battery and holddown strap.
6. Connect cables, positive cable first.
7. Coat battery cable clamps and battery terminals with
a protective anti-corrosive coating such as petroleum
jelly.
