MAINTENANCE:
WHEN DOING MAINTENANCE, YOU MAY BE EXPOSED TO HOT SURFACES, WATER
PRESSURE, MOVING PARTS, OR FIRE WHICH MAY RESULT IN SERIOUS INJURY OR
EVEN DEATH. BEFORE PERFORMING ANY MAINTENANCE OR REPAIR, LET THE
ENGINE COOL DOWN COMPLETELY AND RELEASE ALL WATER PRESSURE. THE
ENGINE CONTAINS FLAMMABLE FUEL. DO NOT SMOKE OR WORK NEAR OPEN
FLAMES WHILE PERFORMING MAINTENANCE.
Nozzle cleaning:
If the nozzle becomes clogged with foreign material, such as sand, flow will
cease or become restricted. Clean the nozzle immediately using the nozzle
cleaner supplied and the following instructions:
•
Shut off the pressure washer and turn off the water supply.
•
Pull trigger on gun handle to relieve any built up water pressure.
•
Remove the nozzle from the lance assembly.
•
Turn the nozzle end up.
•
The nozzle hole is approximately 1mm in diameter, it is the smallest
hole in the system, even a single grain of sand can block the nozzle.
•
Clean the nozzle using the nozzle cleaner provided or wire of
appropriate size. Insert into the nozzle end and push. Remember that
any obstruction will have been lodged in place under very high pressure
and may require an equal amount of force in the opposite direction to
dislodge it.
•
It is important that you see the obstruction come out of the lance,
otherwise the nozzle may block again.
•
Reconnect nozzle to lance and turn on water supply.
•
Recommence operation.
Water Inlet Screen Cleaning:
The water inlet filter screen should be checked periodically and cleaned whenever necessary.
1. Remove the water inlet hose connection to expose the inlet filter.
2. Remove the filter screen and flush with clean water from both sides.
3. Replace the cleaned filter screen into the water inlet connector.
4. Tighten securely (clockwise)
Do not operate the pressure washer without a water inlet filter installed.
Check High Pressure Hose:
The high pressure hose can develop leaks from wear, kinking or abuse. Inspect the hose each time before using
it. Check for cuts, leaks, abrasions or bulging of cover, damage or movement of couplings. If any of these
conditions exist, replace the hose immediately.
The high pressure stream of water that this equipment produces can cut through skin and its
underlying tissues, leading to serious injury and possible amputation.
•
Never repair high pressure hose. Replace it.
•
Replacement hose rating MUST exceed maximum pressure rating of unit.
