3. PRE-OPERATION FOR STARTING
(See Fig. )
1. CONNECT SUCTION HOSE (See Fig. - )
Use a reinforced-wall or wire braided hose to prevent
suction collapse. Since the pump self-priming time is
directly proportional to hose length, a short hose is
recommended.
CAUTION
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 casing.
2. CONNECT DELIVERY HOSE (See Fig. - )
When using a fabric hose, always use a hose band
to prevent the hose from disconnecting under high
pressure.
3. CHECK ENGINE OIL (See Fig. - )
Before checking or refilling engine oil, be sure the
engine is located on stable, level surface and stopped.
■ 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 the following recommended oil.
■ Use 4-stroke automotive detergent oil of API
service class SE or higher grade (SG, SH or SJ is
recommended).
■ Select the viscosity based on the air temperature at
the time of operation as shown in the table.

4. CHECK FUEL (See Fig. - )
WARNING
■
Do not refuel while smoking, near an open
flame or other such potential fire hazards.
Otherwise fire accident may occur.
■
Remove the statistic electricity from your
body before refilling the gasoline.
Sparking from electrostatic discharge may
cause the ignition to the vaporized fuel
(gasoline) resulting burns.
Static electricity can be discharged from the
body by touching by hand the metal parts of
the unit and the fuel dispensing pump.
NOTE
THIS ENGINE IS CERTIFIED TO OPERATE
ON AUTOMOTIVE UNLEADED GASOLINE.
■ Stop the engine and open the cap.
■ Use automotive unleaded gasoline only.
●
Unleaded regular/premium or reformulated
gasoline containing no more than 10% Ethanol
(E10), or 15% MTBE may also be used.
●
Never use gasoline containing ethanol exceeding
10%, or MTBE exceeding 15% because engine
or fuel system damage could result.
●
Never use stale or contaminated gasoline.
●
Use of these non-recommended fuels may result
in reduced performance and/or denial of warranty.

Maximum Fuel level
■ When filling the fuel tank, always use the fuel filter
screen.
■ Reattach the fuel cap by turning clockwise until
reaching the physical stop (about one quarter turn).
Do not attempt to turn past the physical stop or the
fuel cap may be damaged.
■ Wipe off any spilled fuel before starting the engine.
