8. ADJUSTING THROTTLE
OPERATION
1 To increase the speed
of the engine and water
flow, move the throttle
down towards the Start
position.
2 To decrease the speed
of the engine and water
flow, move the throttle
up towards the Stop
position.
3 Ensure the throttle is locked in place after any adjustments by
rotating in a clockwise direction.
The throttle is used to regulate the rotational speed of the engine, which
also controls the water flow out of the discharge outlet.
Before storing the pump, it is recommended to empty the pump body of
any water.
In some cases air may develop in the fuel lines restricting the fuel from
entering the injector. To bleed air from the system follow the steps
below.
1 Unscrew and remove
the air filter wing nut
and washer.
1 Remove the fuel
injection pipe by turning
the nut anti-clockwise.
3 Press the
decompression lever
down.
3 Insert the filter and
secure with the filter
cover and nut.
Turn the drain screw
anti-clockwise and remove from
the pump body to allow excess
water to drain out.
Ensure that the drain screw is
fitted once all water has drained
out.
2 Remove the cover and the
air filter. Check that the filter
is intact and clean, if not
rinse with water and allow to
dry or replace the filter.
2 Open the fuel tap by rotating
clockwise to the “O” position.
4 Pull the recoil starter slowly
until you feel resistance.
Repeat steps 3-4 until a
steady stream flows from the
fuel pipe.
