HIGH PRESSURE HOSE
Attach the high pressure hose to the fitting located on the
pump. (See Figure 2, page 6).
NOTE: DO NOT use a high pressure hose from
another manufacturer.
WATER CONNECTION
Before connecting to unit, run water through the garden
hose (not supplied) to flush out any foreign matter. Check that
the screen is clean and is in the inlet of the pump. Attach
garden hose to the pressure washer water inlet. (See Figure 2,
page 6).
NOTE: The water supply must provide a minimum of
4 g.p.m. at 20 p.s.i. or the pump will be damaged.
START-UP PROCEDURE
1. Make sure water supply is connected and turned on.
2. Release gun safety if locked.
3. To allow air to escape from the hose, squeeze trigger on
the gun until there is a steady stream of water coming
from the nozzle.
4. Remove any dirt or foreign matter from the gun outlet and
the male connector of the wand.
5. Insert the nozzle wand into the gun wand and tighten the
twistfast fitting securely by hand.
STARTING THE ENGINE (See Figure 2, page 6)
1. Check oil and fuel level.
2. Adjust choke prime as necessary.
3. Set the engine switch to the “ON” position.
4. Squeeze trigger on pressure washer to release pressure
while pulling on the engine starter rope with a fast steady
pull. Pressure may otherwise build up making starting the
unit difficult.
5. As the engine warms up, readjust the choke.
1. Attach injection tube assembly to the siphon injector on
the pump. (See Figure 2, page 6).
2. Open a container of Coleman® Powermate® Pressure
Washer Chemical and place next to the unit near the
injection tube.
3. Visually inspect strainer at the end of the injection tube to
verify that it is not clogged.
4. Insert the injection tube into the container all the way to
the bottom.
5. If chemical injection is adjustable, set injection rate by
turning valve clockwise until it is tight. Then turn valve
counterclockwise to increase injector rate and clockwise
to decrease injector rate.
6. If your pressure washer is equipped with removable
nozzles, remove the high-pressure nozzle from the wand
and install the black injection nozzle. The solution will
automatically be mixed with the water and discharged
through the nozzle.
7. If your pressure washer is equipped with an adjustable
nozzle, the low pressure nozzle position should be used
when operating the chemical injector to apply chemicals.
When low pressure is required, grasp and slide the nozzle
cover away from the gun.
NOTE: For certain models, if the engine throttle is not in
the “fast” position, the injection of the solution
may be decreased or stopped.
If the wand is not securely locked into place, it could be
ejected under high pressure when operating the gun,
possibly causing injury or damage.
