Operating Instructions
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 level in the pump.
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 = 3 gpm
Then required flow = 3 x 1.20 = 3.6 gpm
5 gallons / 3.6 gpm = 1.39 minutes
1.39 min x 60 sec/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.) Before Starting
WARNING: Make sure all switches and controls are
in the OFF position prior to plugging in the cord.
DO NOT stand in water while plugging or unplugging
electrical cord.
WARNING: Use a UL recognized receptacle
protected by a ground fault interrupter and
extension cord of proper voltage and amperage at
all times.
1. Connect electrical cord to specified NEMA receptacle.
See page 4.
WARNING: Check hoses, fittings, wand, trigger gun
and fuel connections daily for signs of wear, cracks
and looseness. Replace as required.
2. Connect water supply hose to the garden hose
connector located on the pump.
3. Fill the burner fuel tank. We recommend kerosene
because it burns cleanest. #1 grade home heating
oil, #1 or #2 diesel can also be used. DO NOT USE
GASOLINE OR CRANKCASE OIL.
4. If detergents will be used, only use detergents
intended for pressure washers. Follow instructions
on the detergent container.
IV.) To Start
DANGER: Do not point the spray wand at yourself or
at any person. Bodily injury may result from water
under high pressure.
WARNING: Wear eye, ear, hand, foot and skin
protection at all times while operating this pressure
washer.
IMPORTANT: The water must be turned on before
starting. Running the pump dry will cause damage
and void warranty.
1. Turn water supply ON.
2. Squeeze the trigger to allow air to purge from the
system. (This step goes faster with the pressure nozzle
removed)
