Clarke Power Wash EHD130, Operating & Maintenance Instructions

Page: 8 / 14

SHUTTING DOWN THE MACHINE
If the chemical injection facility has been used, disconnect the plastic tube from the
pick-up, and turn the pressure adjuster on the lance to HIGH pressure. Allow the pump to
run for a short while to cleanse the hose and lance, then switch OFF the pump.
Switch OFF at the mains electrical supply, and turn OFF the water supply -
disconnect where appropriate.
IMPORTANT: Operate the lance trigger once more to ensure there is no pressure in
the high pressure hose.
NEVER disconnect the high pressure hose unless you have operated the trigger.
AFTER EACH USE
When using chemical detergents,
always ensure the system is
thoroughly flushed out after use as
described previously.
Ensure the hoses and power cable
are coiled and properly stowed. DO
NOT allow them to be left casually, in
a heap. This invites damage and will
cause rapid deterioration.
STORAGE
Store the Washer in an horizontal position, preferably under cover, protected from
the elements.
If there is a danger of freezing, the pump should be filled with antifreeze by inserting
the inlet and outlet hoses into a bucket of antifreeze as shown in the diagram,
start the machine and allow the antifreeze to circulate. After a short time stop the
machine using the procedure outlined on page 6, and store the machine with
the antifreeze still within the pump body.
NOTE :
If you experience difficulty in starting the motor following a long period of storage,
it is possible that the seals within the pump have dried out and are gripping the
pistons. This problem may be alleviated by storing the machine with antifreeze
within the pump body, as described above.
MAINTENANCE
WARNING: Ensure the plug is removed from the socket before carrying out any
adjustment, servicing or maintenance.
