MAINTENANCE
BATTERY
Batteries normally produce explosive gases which can cause personal injury. Do not allow flames, sparks or
any ignited object to come near the battery. When charging or working near battery, always shield your eyes
and always provide proper ventilation.
Battery cable should be disconnected before using “Fast Charge.”
Charge battery at 15 amps for 10 minutes or 7 amps for 30 minutes. Do not exceed the recommended
charging rate. If electrolyte starts boiling over, decrease charging.
Always remove grounded (-) battery clamp first and replace it last. Avoid hazards by:
1. Filling batteries in well-ventilated areas.
2. Wear eye protection and rubber gloves.
3. Avoid breathing fumes when electrolyte is added.
4. Avoid spilling or dripping electrolyte.
Battery Electrolyte is an acidic solution and should be handled with care. If
electrolyte is splashed on any part of your body, flush all contact areas imme -
diately with liberal amounts of water. Get medical attention immediately.
Use of booster battery and jumper cables. Particular care should be used
when connecting a booster battery. Use proper polarity in order to prevent
sparks.
TO JUMP START (NEGATIVE GROUNDED BATTERY):
1. Shield eyes.
2. Connect ends of one cable to positive (+) termi-
nals of each battery, first (A) then (B).
3. Connect one end of other cable to negative (-)
terminal of "good" battery (C).
4. Connect other end of cable (D) to engine block
on unit being started (NOT to negative (-) termi-
nal of battery)
To prevent damage to other electrical components on
unit being started, make certain that engine is at idle
speed before disconnecting jumper cables.
STORAGE
If the engine will be out of service for two or more months, use the following storage procedure.
1. Clean the exterior surfaces of the engine.
2. Change the oil and filter while the engine is still warm from operation.
3. The fuel system must be completely emptied, or the gasoline must be treated with a stabilizer to prevent deteriora-
tion.
If you choose to use a stabilizer, follow manufacturers recommendations, and add the correct amount for the ca-
pacity of fuel system. Fill fuel tank with clean, fresh gasoline. Run engine for 2-3 minutes to get stabilized fuel into
carburetor. Close fuel shut-off valve when unit is being stored or transported.
To empty the system, drain fuel tank and carburetor, or run engine until tank and system are empty.
4. Remove the spark plugs. Add one tablespoon of engine oil into each spark plug hole. Install plugs, but do not con-
nect the plug leads. Crank the engine two or three revolutions.
5. Store machine in a clean, dry place.
