ASSEMBLY PROCEDURES
Blow pipes to main body (Fig. 1)
Inspect the main body and accessories.

○ If genuine oil is not available, use an anti-oxidant added quality
oil expressly labeled for air-cooled 2-cycle engine use (JASO
FC GRADE OIL or ISO EGC GRADE). Do not use BIA or TCW
(2-stroke water-cooling type) mixed oil.
○ Never use for four-stroke engine oil or waste oil.
○ Always mix fuel and oil in a separate clean container.
Always start by fi ling half the amount of fuel, which is to be used.
Then add the whole amount of oil. Mix (shake) the fuel mixture. Add
the remaining amount of fuel.
Mix (shake) the fuel-mix thoroughly before fi lling the fuel tank.
Fueling
WARNING
○ Always shut off the engine and let it cool for a few minutes
before refueling.
○ Slowly open the fuel tank, when fi lling up with fuel, so that
possible over-pressure disappears.
○ Tighten the fuel cap carefully, after fueling.
○ Always move the unit at least 3 m from the fueling area before
starting.
○ Do not smoke and/or allow fl ames or sparks near fuel when
handling or fi lling fuel.
○ Always wash any spilled fuel from clothing immediately with
soap.
○ Be sure to check for any fuel leakage after refueling.
Before fueling, clean the tank cap area carefully, to ensure that
no dirt falls into the tank. Make sure that the fuel is well mixed by
shaking the container, before fueling.
Starting
CAUTION
Do not start if the pipe and guard net is obstructed.
1.
Check the switch (7) to ON position. (Fig. 4)
* Push priming bulb (8) about ten times so that fuel fl ows into
carburetor. (Fig. 5)
2. Set choke lever to CLOSED position. (Fig. 6)
3. Pull recoil starter briskly, taking care to keep the handle in your
