Preventive Maintenance
Daily Checks
Regular inspection of your pressure washer is the key to prolong its life.
Follow these simple daily checks
religiously.
1. Check air filter for dirt and clean or replace as required.
2. Check engine oil level. (Dipstick is attached to inside of oil cap.)
3. Check engine fuel level.
4. Check high pressure hose for kinks, twists or damage. Replace
any damaged hose.
5. Check that the pump oil level is within operation range on the
pump dipstick or to the centre of the sight glass.
6. On units with a gearbox, check that the gear box oil level is within
operation range on the gear box dipstick.
7. Check that the water supply is adequate for your machine.
8. Check water inlet screen and clean when necessary.
9. Check the chemical supply.
Preventive Maintenance
1. Change pump oil and, if so equipped, gearbox oil, after every 250
hours. (Pump uses 30W non-detergent oil. If your pressure
washer is equipped with a gear box, use 90W oil for gearbox.)
2. See engine manufacturer's manual for oil change intervals.
(Engine uses SAE 10-30W.)

Pressure Washer Troubleshooting

NOTICE: Most problems with pressure washers are not a malfunction
of the pump or motor!! ALWAYS trouble shoot from water source and/or
nozzle towards the pump and motor. Example: Check water supply
and nozzle if pressure fluctuates, unit is noisy or does not reach full
pressure.
Introduction
With proper care and use of the pressure washer, the unit should
remain free of problems. Most problems are caused by careless or
improper use of the equipment. Operation of the unit without an inlet
water supply will result in damage to the seals and other components.
Another common cause of damage is running the unit for long periods
with the spray gun trigger in its "Closed" position.
The latter can result in high water temperatures, resulting in damage to
seals and other components.
