5. OPERATION
5.1 WATER CONNECTIONS
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.
IMPORTANT!
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).
IMPORTANT!
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
.
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 65
°
C (149
°
C). Water that exceeds this
temperature can damage the pump seals causing crankcase oil to mix with water flow.
5.2 BEFORE STARTING YOUR PRESSURE WASHER
Follow this list before using the washer and each time thereafter to maintain the unit in good condition:
1. Be sure you understand all safety precautions outlined in Section 2 and from the labels/decals applied
to the pressure washer.
2.
REPLACE THE SHIPPING OIL CAP WITH THE OIL BREATHER CAP
. The oil breather cap is
included with the pump in a small plastic bag.
THE OIL BREATHER CAP MUST BE INSTALLED
IMMEDIATELY BEFORE USE
.
3.
CHECK THE PUMP OIL LEVEL
:
•
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.
•
Replace 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.
4.
CHECK THE ENGINE OIL LEVEL
.
THE ENGINES DO NOT COME WITH OIL!
Use the markings on
the oil dipstick to determine the required amount. Do not overfill. Consult the engine owner’s manual
for details.
5. Ensure the pressure washer is sitting level on firm ground.
6. Check for loose hardware. Tighten if necessary.
7. Check for water leaks at fittings. Tighten loose fittings or apply Teflon tape. Replace any damaged or
worn components.
8. Ensure that the plastic screen is in the water inlet swivel ring with the tip pointing up.
