MAINTENANCE
2.20
New Batteries: Batteries must be fully charged
before use or battery life can be reduced by
10-30% of full potential . Charge battery for 3--5
hours at a current equivalent of 1/10 of the
battery’s rated amp/hour capacity (i.e. 12amp hr
x .10 = 1.2 amp charging). Do not use the
alternator to charge a new battery.
Low--Maintenance batteries are permanently
sealed at the time of manufacture. The use of
lead--calcium and AGM technology instead of
lead--antimony allows the battery acid to be fully
absorbed. For this reason, a Low--Maintenance
battery case is dark and the cell caps are not
removable, since there is no need to check
electrolyte level.
NEVER attempt to add electrolyte or water to a
Low--Maintenance battery. Doing so will damage
the case and shorten the life of the battery. Refer
to the Battery Maintenance Video (PN 9917987) for
proper instruction on servicing batteries.

SPARK PLUG
1. Remove spark plug high tension lead. Clean plug
area so no dirt and debris can fall into engine
when plug is removed.
2. Remove spark plug.
3. Inspect electrodes for wear and carbon buildup.
Look for a sharp outer edge with no rounding or
erosion of the electrodes.
4. Clean with electrical contact cleaner or a glass
bead spark plug cleaner only. CAUTION: A wire
brush or coated abrasive should not be used.
5. Measure gap with a wire gauge. Refer to
specifications for proper spark plug type and gap.
Adjust gap if necessary by bending the side
electrode carefully. (Ill. 1)
6. If necessary, replace spark plug with proper type.
CAUTION: Severe engine damage may occur if
the incorrect spark plug is used.
7. Apply a small amount of anti-seize compound to
the spark plug threads.
8. Install spark plug and torque to specification.
