-t)
-
WARNING
Use a reinforced-wall or wire braided hose to prevent suction
collapse.
Do not refuel while smoking, near an open flame
or other such potential fire hazards. Otherwise
fire accident may occur.
Since the pump self-priming time is directly proportional to
hose length, a short hose is recommended.
CAUTION
NOTE
Always use a strainer with the suction hose. Gravel
or debris sucked into the pump will cause serious
damage to the impeller and the pump casting.
THIS ENGINE IS CERTIFIED TO OPERATE ON
AUTOMOTIVE UNLEADED GASOLINE.
■ Stop the engine and open the cap.
■ Use unleaded automotive gasoline only.
• Unleaded regular/premium or reformulated gasoline
containing no more than 10% Ethanol (E10), or 15%
MTBE may also be used.
2. CONNECT DELIVERY HOSE
(See Fig. 2-w)
When using a fabric hose, always use a hose band to prevent
the hose from disconnecting under high pressure.
• Never use gasoline containing ethanol exceeding
10%, or MTBE exceeding 15% because engine or
fuel system damage could result.
3. CHECK ENGINE OIL (See Fig. 2-r)
• Never use stale or contaminated gasoline.
• Use of these non-recommended fuels may result in
reduced performance and/or denial of warranty.
Before checking or refilling engine oil, be sure the engine is
located on stable, level surface and stopped.
Fuel Tank Capacity
■ Do not screw the oil gauge into the oil filler neck to check
oil level. If the oil level is low, refill to the upper level with

2. PUMPING VOLUME IS SMALL.
■
Is the stop switch at position “ I ” (ON)?
■
Sucking air at suction side.
■ Remove and inspect the spark plug.
(Check piping at suction side.)
If the electrode is fouled, clean or replace it with new
one.
■
Drop off engine output
(Consult your nearest dealer.)
■
Remove the spark plug and connect it to the plug cap.
■
Breakage of mechanical seal.
Pull the starter handle while grounding spark plug against
engine body. Try with a new spark plug if the spark is
weak or there is no spark.
(Consult your nearest dealer.)
■
High suction lift (Lower.)
■
Suction hose is too long or thin.
The ignition system is faulty if there is no spark with a
new spark plug.
(Use a thick hose in minimum length.)
■
Leak of water from water passage.
WARNING
(Stop leaking.)
