Operation - Clarke JETSTAR 1800 Operating & Maintenance Instructions

B. Lance
At the opposite end to the nozzle is a
spigot with two integral lugs, and a
rubber O-ring. Ensure the O-ring is in
place and in good condition.
Insert the spigot end of the nozzle into the
handle/lance assembly. Push home firmly
to lock it in position. Twist anticlockwise
looking down from the handle end. DO
NOT attempt to disassemble the lance/
handle assembly.
NOTE: When new, the lance may be a tight fit and a little lubrication, with
vaseline or similar, will assist when joining the parts together.
C. Nozzle
The nozzle simply screws into the end of the lance.

OPERATION

Make certain the ON/OFF switch is set in the OFF position by pressing 'O',
see Fig. 5. Connect the plug to the mains supply, preferably via a Residual
Current Device.
Turn the water tap fully on.
When starting, it is IMPORTANT that you
adopt the following procedure:
In order to ease the starting process, and to
prevent the possibility of blown fuses, pull the
trigger on the lance - it may be necessary to
release the safety latch in order to do so (1,
Fig.6), and hold the trigger in that position
whilst switching the motor ON and allowing
the pump to develop full pressure.
You may release the trigger once full pressure
is developed. When you do so, a by-pass will
operate, shutting off the water at the nozzle,
but the motor will continue to run.
DO NOT allow the motor to run for more than
30-40 seconds under these conditions as
doing so for prolonged periods could
damage the motor
