TRANSPORTING ENGINE
1. Never transport engine inside an enclosed space or
vehicle. Fuel or fuel vapors may ignite causing serious
injury or death.
2. If fuel is present in the fuel tank remove fuel or transport
with an open vehicle in an upright position.
3. If an enclosed vehicle must be used, remove fuel into an
approved red fuel container. DO NOT siphon by mouth.
4. Run engine or drain to use up the fuel in the carburetor
and fuel tank. Always run engine in a well ventilated area.
5. Wipe away any spilled fuel from engine. Allow to dry.
STEPS FOR LONGTERM STORAGE
(30 days or more without use)
1. Mix an appropriate amount of fuel stabilizer to fresh
gasoline, in the ratio recommended on the stabilizer
packaing. Run the engine for ve minutes to distribute
the stabilizer mixture throughout the fuel system. This will
prevent gum, varnish and corrosion build up in your fuel
system during long-term storage for up to 12 months.
NOTE: It is recommended that fuel tank is drained and new
fuel stabilizer is added every four months. Starting engine
once a month to help preserve engine is also recommended.
2. Store engine in its upright position.
3. Remove all debris from engine.
