6.2.2 ROUTINE INSPECTION
Regular inspection is the key to preventing breakdowns and prolonging the life of the equipment. Follow these
procedures faithfully.
1. Daily
a) Check that the nozzle on the spray wand is not clogged or worn.
b)
CHECK PUMP OIL LEVEL.
The oil level should always be at the center of the sight glass
.
c)
CHECK ENGINE OIL LEVEL. It should be within the operating range on the dipstick.
d) Check that the water supply is adequate.
e) Check for loose hardware. Tighten if necessary.
f) Check fittings for water leaks. Tighten fittings and reapply Teflon tape where sealing is required.
2. Weekly
a) Check the pressure hose for wear and damage. A local hydraulic hose service dealer, or your
equipment dealer can repair a damaged hose.
b) Check water inlet filter.
c) Check the engine’s air filter for dirt build up. Replace if necessary.
d) Check the engine’s fuel filter for dirt and sediment. Clean or replace if necessary.
3. Monthly
a) Replace pump oil after the first 50 hours of use. Replace oil every 500 hours of operation
thereafter. Only use non-detergent, SAE 20-30 weight oil designed for pressure washer pumps.
b) Replace the engine oil as recommended by the engine owner’s manual.
6.2.3 PULLEY ALIGNMENT & BELT TENSION (for items 8093262 & 8186751)
Improper pulley alignment and belt tension are causes for engine overloading, excessive vibration and
premature belt or bearing failure. To prevent this from happening, check the pulley alignment and belt tension
on a regular basis.
Periodically, inspect both the engine and pump pulleys for oil, grease, nicks or burrs. Clean or replace pulleys
if necessary. Make sure the pulleys are securely fastened. Align the engine pulley with the pump pulley. The
drive belt grooves of both pulleys should be in line with each other. The engine crankshaft must be parallel to
the pump shaft.
WARNING!
To avoid personal injury, ensure the engine switch is in the OFF position, disconnect the spark
plug and relieve water pressure (i.e. depress trigger) before performing any service on the pressure washer.
1. Belt
Tension
Proper belt tension and pulley alignment must be maintained for maximum drive efficiency and belt
life. The correct tension exists if a deflection (see A in Figure 5 on the next page) of ½” (13 mm)
occurs by placing 10 lb (4.4 kg) of force (see B in Figure 5 on the next page) midway between the
motor pulley and the pump flywheel. This deflection can be adjusted by the following procedure.
