CAUTION: OWNER’S RESPONSIBILITY
Proper care and maintenance is the responsibility of the
owner. The following items are just some of the actions
an owner should take regularly. Failure to maintain the
drive and engine will result in damage and early part
failure, and can void the product warranty.
- Properly store your engine using fuel stabilizer.
Stale fuel will cause damage to the engine and will result
in dicult starting, poor idle, acceleration and top end
speed. Poor fuel delivery can cause an engine lean
condition and may aect the performance and life of the
engine. (See page 22-23.)
- Always use a fuel stabilizer like Stabil when the
engine is stored for more than two weeks.
- Propeller balance and condition. If a propeller is
worn, damaged or bent, it can vibrate and will cause the
following conditions - Loose bolts, handle vibration,
leaking seals, bearing failure, frame cracking and engine
damage. A unbalanced propeller will cause engine and
frame damage which is not covered by warranty.
- Freezing rain and snow can cause severe
damage to the throttle, trim, shift switch and carburetor.
Store the motor with a cover.
Caution: If you have a frozen cable and thaw it out, the water
in the cable will freeze again during driving and can cause the
throttle to stick open. If the throttle cable freezes, it must be
removed, thawed and pressure lubricated with a silicone based
lubricant to remove the water within the cable. Tape a silicone
pressure can nozzle straw to the end of the cable – spray in
lubricant until the water and lubricant exit the opposite cable
end. Or, remove the cable and soak in WD-40 overnight.
