Read and understand the entire manual before operating the pressure washer.
Follow these instructions every time you use the pressure washer.
I.) Pre-Operation
Read entire manual, especially the important safety
instructions.
1.) Check hoses, fittings, wand, trigger gun and fuel
connections
for
signs
of
wear,
cracks
and
looseness, and replace as required.
2.) Check and clean the nozzle orifice.
3.) Check and clean the water inlet screen and filter.
(see Maintenance section).
4.) Check and maintain proper oil levels in the pump
and engine (see Maintenance section).
II.) Connecting City Water Tap
Follow these instructions when supplying water from a
pressurized source such as a garden hose instead of a
water feed tank.
Attach a garden hose to the water inlet (city tap water).
See Machine Component Identification for location of the
water inlet (city tap water).
1.) Make sure the water supply is clean.
Debris can
cause excess pump wear and reduce performance.
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.
It should take less than 62
seconds.
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.) Always use a flexible rubber hose for your water
supply. Do not use rigid piping.
III.) Attach High Pressure Hose
Attach the high pressure hose to the water outlet. See
Machine Component Identification section for location of
the water outlet
Your pressure washer hose is equipped with quick
couplers.
Simply pull the collar back and push the
coupler onto the nipple. Make sure the collar slides over
the ball bearings. Once the connection is made, pull on
the hose to assure a positive connection.
