WARNING
High Pressure Fluid Injection Hazard
High-pressure fluid discharge from leaks (even pin-
sized) or ruptured components can pierce skin and
inject fluid into the body. Injection injury can result in
blood poisoning and/or severe tissue damage leading
to infection, gangrene, and possibly amputation.
• Never use a finger or skin to check for leaks.
• Never operate pressure washer with damaged or
missing hoses/parts.
• Never attempt to repair a high-pressure hose or
component – Always replace it with a part that is
rated at or above the pressure rating of this
pressure washer.

1.) Make sure the water supply is clean. Debris can
cause excess pump wear and reduce performance.

Operation
2.) An insufficient water supply will damage your pump.
Make sure the water supply is steady and is 20%
over the rated flow of your pump. Use a stopwatch
to time how long it takes to fill a 5-gallon bucket with
your garden hose. The bucket must fill faster than
the times listed in the table below.

3.) The water supply garden hose must have an inside
diameter of at least 5/8". If the hose is more than
100 ft. long, the diameter must be at least 3/4".
4.) Never use a reservoir tank as a water source.
Drawing water out of a tank may cause pump
cavitation and damage to your pump. This pressure
washer is designed for a pressurized water source
such as a city water faucet. However, the water
source pressure must not exceed:

157123,157132,157124
157127, 157133
5.) Always use a flexible rubber hose for your water
supply. Do not use rigid piping.
Attach High Pressure Hose to Spray Gun
NEVER operate this pump with components (such as
hose, connections, and spray gun) rated for lower
pressure and/or temperature limits than the pressure
washer's maximum rated pressure and temperature,
or component could rupture and cause serious
personal injury from escaping high pressure fluids.
1. See "Component Identification" section of this
manual for location of the pressure washer's water
outlet.
2. Your pressure washer hose is equipped with quick
couplers. Simply pull the collar back and push the
coupler onto the water outlet nipple. The collar
should slide over the ball bearings.
