Air Cleaner
Improper air cleaner maintenance can
cause engine damage.
Service schedules and cleaning
instructions are the same for all engines,
even though air cleaner designs may
differ (Fig. 6-9).
SERVICE SCHEDULE:
Outer foam pre-cleaner: Wash and re-oil
every 25 operating hours or every
season, whichever occurs first.
Inner paper cartridge: Clean or replace
every 100 operating hours or every
season, whichever occurs first.
AIR CLEANER SERVICING
(Fig. 6-9)
• Unhook clips (C) and/or remove knobs
(D). Remove covers (E). Lift out paper
cartridge (B) and foam pre-cleaner (A).
Separate foam pre-cleaner from paper
cartridge.
• Wash foam pre-cleaner (A) in liquid
detergent and warm water. Squeeze dry
in a clean cloth.
• Saturate foam pre-cleaner in clean
engine oil. Wrap in clean, absorbent
cloth and squeeze to remove all excess
engine oil.
• Clean or replace paper cartridge (B) if
necessary. To clean: Tap gently against
a flat surface. If very dirty, replace.
• Reassemble air cleaner components.
Tighten knobs (D) securely. Clip cover
assembly (E) onto air cleaner body.
Carburetor
The carburetor is adjusted at the factory.
It should not need to be reset.
If a black exhaust is noted, check the air
cleaner first. An over-rich mixture is
usually caused by a poorly serviced or
clogged air cleaner element, not an
improperly adjusted carburetor. If
readjustment is necessary, refer to
engine manual or contact your dealer for
servicing.
Battery
NOTE: The battery is sealed and is
maintenance-tree. Acid level cannot be
checked.
Keep battery cables and terminals clean.
If cables are corroded, clean them. After
cleaning the battery and terminals, apply
a light coat of petroleum jelly or grease
to the terminals and over the bolt.
Reposition the insulated boot over the
positive (+) terminal to prevent shorting.
If removing the battery, remove the
negative (-) cable first, followed by the
positive (+) cable.
When installing the battery, always
check the polarity of the battery
terminals. Make sure the battery is not
reversed. The negative (-) cable is
grounded. Connect the positive (+) cable
first and then connect the negative (-)
cable.
CHARGING: If the unit has not been used
for an extended time period, charge the
battery at 6 to 10 amps for 1 hour.
A WARNING
BATTERIES GIVE OFF HIGHLY
EXPLOSIVE GAS DURING AND FOR SOME
TIME AFTER CHARGING. DO NOT ALLOW
A SPARK OR OPEN FLAME NEAR
BATTERY.
