Operating Instructions
Read and understand the entire manual before operating the pressure washer.
Follow these instructions every time you use the pressure washer.
I.) Pre-Operation
;
A.) Position the machine for easy access to all
controls.
;
B.) Position the machine on a solid surface, with
less than a three degree slope, and so it is
protected from external damage.
;
C.) Position the machine so that ambient lighting is
sufficient for the surface you are cleaning can be
seen easily. Use artificial light if needed.
;
D.) Check hoses, fittings, wand, trigger gun and fuel
connections for signs of wear, cracks and
looseness. Replace as required.
;
E.) Check and clean the nozzle orifice.
;
F.) Check and clean the water inlet screen and
filter.
;
G.) Read entire manual, especially the important
safety instructions listed on page 2.
;
H.) Check and maintain proper oil levels in the
pump and engine.
II.) Check Your Water Supply
;
A.) Make sure the water supply is clean. Debris can
cause excess pump wear and reduce
performance.
;
B.) 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.
Example:
If the rated flow is = 3gpm
Then required flow = 3 x 1.20 = 3.6gpm
5gallons / 3.6gpm = 1.39 minutes
1.39min x 60sec/min = 83 seconds
Therefore, you must be able to fill a
5 gallon bucket in 83 seconds or faster.
;
C.) 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”.
;
D.) Never use a reservoir tank as a water source.
This pressure washer is designed for a
pressurized water source such as a city water
faucet. Sucking water out of a tank may cause
pump cavitation and damage to your pump.
However, the inlet pressure of the pump must
not exceed 115 psi (8 bar).
;
E.) Always use a flexible rubber hose for your water
supply. Do not use rigid piping.
;
F.) Do not pump flammable liquids or liquids
containing incompatible chemicals or solvents.
III.) Attach Garden Hose
Your pressure washer is equipped with a garden hose
quick couplers. Follow these steps to use the quick
couplers.
A.) Spin the coupler onto your garden hose.
B.) Pull back the collar on the coupler.
C.) Snap the coupler onto the water inlet.
IV.) Attach High Pressure Hose
Your pressure washer hose is equipped with quick
couplers. Pull the collar back and push the coupler onto
the water outlet nipple. Make sure the collar slides over
the ball bearings. Once the connection is made, pull on
the hose to assure a positive connection. Connect the
hose to the gun in the same manner.
