OPERATION
CONNECTING TO WATER SUPPLY
Water is supplied to the pump from an external source, normally a garden hose. To safely and efficiently use the
pressure washer, follow this procedure:
1. Connect the water hose (not supplied) to the inlet swivel ring at the water tap.
NOTICE: The hose should not be longer than 25 feet to avoid pressure-drop related problems.
2. The water supply should be pressurized (not exceeding 125 PSI).
NOTICE: If the water is used from an open source, use extra screens and a filter to remove all grit
and contaminants.
3. A water supply must meet the following specifications:
a. For proper performance, the supply water flow must be 1.5 to 2 times what the pump requires.
For example, if the unit is rated at 3 gallons per minute (GPM), then the supply water flow should be
4.5 to 6 GPM.
b. Do not allow the inlet water temperature to exceed 65ºC (149ºF). Water that exceeds this temperature can
damage the pump seals, causing crankcase oil to mix with water flow.
BEFORE STARTING YOUR PRESSURE WASHER
Follow this procedure before using the washer and each time thereafter to maintain the unit in good condition:
1. Replace the shipping oil cap with the oil breather cap. The oil breather cap is included with the pump (#37) in a
small plastic bag. The oil breather cap must be installed immediately before use.
2. Check the pump oil level:
a. Pump oil level must be at the center of the sight glass. Do not over fill or under fill as it could damage
the pump.
b. Replace oil after the first 50 hours of use. Replace oil every 500 hours of operation thereafter.
c. Only use non-detergent, SAE 20-30 weight oil designed for pressure washer pumps.
3. Check the engine oil level. Use the markings on the oil dipstick to determine the required amount. Do not
overfill. Consult the engine owner's manual for details.
NOTICE! The engine is not shipped with oil. Starting the engine without oil will damage the engine
beyond repair.
4. Ensure the pressure washer is sitting level on firm ground.
5. Check for loose hardware. Tighten if necessary.
6. Check for water leaks at fittings. Tighten loose fittings or apply thread tape. Replace any damaged or
worn components.
7. Ensure that the plastic screen inside inlet port is in the water inlet swivel ring with the tip pointing up.
STARTING THE PRESSURE WASHER
When using the pressure washer for the first time or after a long storage period, follow this procedure to ensure that the
pump primes:
1. Prepare unit and worksite. Turn on the supply water.
2. Hold the trigger for at least one minute until the spray leaves the nozzle in a steady stream (no sputtering).
3. Start the engine.
