1. Set the engine On/Off switch to
On.
2. Move the fuel valve to the right
side (open position).
3. Pull the starter recoil rope slowly
two or three times to allow fuel to
reach the carburetor.
• The direction of operation is
marked on the machine.
4. To start a cold engine, set the
choke lever to the left (closed
position), but if the engine is
already warm, the choke should
be in the open position to the
right.
5. Set the throttle about one third
open.
6. Pull the recoil starter rope firmly
until the engine starts. Do not
snatch at the starter rope and allow it to recoil slowly after each pull.
7. Once the engine starts, gradually return the choke to the open position as
the engine warms up and use the engine throttle to gradually increase
engine speed.
CONTROL DURING OPERATION
After starting the engine, move the throttle to the open position for priming of
the pump and checking for pump output. Output is controlled by adjusting
the engine speed.
The pump should begin discharging liquid in a few moments. To further reduce
priming time, the engine speed may be increased after the engine is properly
run in. If pumping does not start within this time, shut off engine and check
carefully to find the problem. See TROUBLESHOOTING.
NOTE: Filling the suction pipe with water will speed up the priming
process, and it is recommended that a non-return valve be fitted
to the end of the suction pipe.
On higher vertical lifts, a higher engine speed is necessary but on shallow lifts
or when there is little water to pump, preserve fuel and engine wear by
reducing engine speed.
In the event of blockages, where debris has entered the suction chamber, the
suction chamber can be opened and cleaned out by removing the bolts (12)
shown in the layout on page 18.
