Operation
Step 1. Connect Hoses, Water Supply, and
Spray Nozzle
Note: The electrical power and pump are both off
during Step 1 procedures.
Attach Garden Hose to Water Supply
1. Acquire a suitable garden hose:
•
The water supply garden hose must have an inside
diameter of at least 5/8”. If the hose is more than
100 ft. long, th e diameter must be at least 3/4”.
•
Always use a flexible rubber hose for your water
supply. Do not use rigid piping.
•
The use of a backflow preventer on the supply hose
is recommended and may be required by local code.
2. Attach garden hose to water supply.
Check Water Supply
•
Make sure the water supply is clean. Debris can
cause excess pump wear and reduce performance.
•
Make sure the water supply is steady and capable of
flowing at a rate 20% over the rated flow of your
pump. An insufficient water supply will damage your
pump. Use a stopwatch to time how long it takes to
fill a 5-gallon bucket with your garden hose. It
should take less than 100 seconds.
Connect Water Supply to Pump
•
Confirm rubber washer and inlet filter screen are in
water pump inlet. (See “ Component Identification ”
section for location of water inlet)
•
Run water through garden hose for 30 seconds to
clean out debris. Turn off water.
•
Connect garden hose to water pump inlet on
pressure washer and turn on water valve.
Connect Pressure Hose to Pump
Uncoil high-pressure hose. Attach quick connect end of
hose to pressure
washer’s water outlet and other end of
high-pressure hose to spray g un by following the “ Quick
Connect Procedure ” below.
WARNING: Incompatable component
hazard
NEVER operate this pump with components (such as
hose, connections, and spray gun) rated for lower
pressure and/or temperature limits than the machine’s
maximum rated pressure and temperature, or
component will likely rupture and cause serious
personal injury from escaping high pressure fluids.
Quick Connect Procedure
•
Pull quick connect collar back (Figure 9a).
•
Push hose or nozzle firmly against stop.
•
Let go of collar (Figure 9a).
•
Pull (hose or nozzle) to assure a tight connection.
Select Spray Nozzle
Five high-pressure nozzles and one low-pressure nozzle
are supplied.
Note: A wider angle produces a lower impact pressure
on surface. Nozzles from other sources may not fit the
coupler and become a hazard.
