USING THE OPTIONAL HIGH-PRESSURE WATER PUMP
HIGH PRESSURE WATER CAN BE HAZARDOUS, ALWAYS WEAR GOGGLES OR SUITABLE
EYE PROTECTION WHEN OPERATING WITH HIGH PRESSURE WATER. EXERCISE
EXTREME CARE WHEN USING THE LANCE, DO NOT DIRECT THE JET AT OTHER PEOPLE.
WHEN CLEANING PUBLIC BUILDINGS OR STREET FURNITURE, ENSURE THAT NO
ELECTRICAL CONNECTIONS ARE EXPOSED.
FAILURE TO COMPLY CAN RESULT IN SERIOUS INJURY.
Do not direct the high pressure jet directly at paint work or at electrical connections,
this could result in damage to the vehicle.
This pump should NEVER be permitted to run dry, as this will quickly destroy the
piston seals and cause the pump to fail. If the pump shuts off in-use the most likely
cause will be low water activating the auto shut-off float switch in the tank.
1.
Ensure that there is sufficient water in the water tank. A float switch
in the water tank will operate to stop the pump before the water
level is too low for safe operation.
2.
Start the auxiliary engine and activate the main
control panel.
3.
If the machine is fitted with a front-mounted high-
pressure spray bar, adjust the ball valve to supply the spray bar or
the hand-lance as required (Refer to Fig. 8).
4.
Switch on the high pressure pump (engine speed will
automatically increase to 1600 rpm).
Increasing engine speed will not increase pump performance
