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 to be
seen with ease. Use artificial light if needed.
;
D.) Check hoses, fittings, wand, trigger gun and fuel
connections for signs of wear, cracks and
looseness, and 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 = 4gpm
Then required flow = 4 x 1.20 = 4.8gpm
5gallons / 4.8gpm = 1.04 minutes
1.04min x 60sec/min = 62 seconds
Therefore, you must be able to fill a
5 gallon bucket in 62 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 75 psi (5.25 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
Remove shipping plug from pump inletand confirm
rubber washer is in place. Attach garden hose.
IV.) Attach High Pressure Hose
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.
