5. Remove oil plug on top of pressure washer pump
and replace with dipstick supplied. (This may be in-
stalled from the factory.)
6. Check oil level on oil dipstick on top of pump. Oil
should be visible one half way up sight glass (30W
non-detergent).
OPERATING INSTRUCTIONS
1. Read safety and preventative maintenance instruc-
tions before starting machine.
2. With power switch in OFF position, plug power cord
into a grounded type of receptacle of proper voltage
and amperage reading.Then push GFCI reset button
at end of power cord if required.
3. Turn on water at faucet and pull trigger on spray gun
allowing water to flow until all air has discharged from
system. Check for water leaks; tighten as needed.
4. Push the switch on and pull the trigger on the spray
gun to activate a pressure switch which will then start
the machine. (Auto start option only).
5. Turn the variable pressure control handle clockwise
to increase pressure.
6. To apply detergent read “How to Use The Detergent
Injector.”
SHUTDOWN PROCEDURES
1. Rinse with clean water to remove any soap residue,
by placing detergent hose into fresh water bucket
and operating injector as described below.
2. Release the trigger on the spray gun which will acti-
vate a timer to shut the machine off after four (4)
seconds. Turn the switch off if the machine is going
to be left unattended. (Auto start option only).
3. Turn off water supply.
4. Open spray gun to relieve remaining pressure.
5. Remove water supply hose.

WARNING
SOME DETERGENTS
MAY BE HARMFUL IF
INHALED OR
INGESTED
HOW TO USE
THE DETERGENT INJECTOR
WARNING: Some detergents may
be harmful if inhaled or ingested
causing severe nausea, fainting or
poisoning.The harmful elements
may cause property damage or
severe injury.
The machine can siphon and mix
detergents with the use of Shark's
detergent injector kit.
1. Pull injector quick coupler collar back and secure on
discharge nipple. Injector valve body arrow should
point in direction of flow.
2. Connect high pressure hose to injector nipple secur-
ing quick coupler.
3. Start machine as outlined in Operating Instructions.
4. Place detergent pickup tube into container of deter-
gent solution.
5. Install the brass soap nozzle provided with the injec-
tor into the quick coupler of the wand.
6. Open spray gun. Water detergent ratio is approxi-
mately 15 to 1.
7. When you finish washing, rinse by simply releasing
the spray gun, removing the soap nozzle, and re-
placing the pressure nozzle back into quick coupler.
NOTE:The detergent injector will not siphon with
the high pressure nozzle at the end of the wand.
8. If your machine has a variable pressure wand, turn
the pressure control handle counterclockwise to lower
the pressure.This directs the water flow through the
soap nozzle, allowing the detergent injector to si-
phon soap. To rinse with high pressure water, simply
turn the control handle clockwise.
9. For clean up, place detergent pickup tube into con-
tainer of clear water and follow steps 5 and 8 to pre-
vent detergent deposits from damaging the injector.

GENERALWASHING
TECHNIQUES
Hold spray nozzle a foot or so from the surface being
cleaned. Spray at an angle to get under the material and
lift it off.
When washing large objects, use detergent injector to
apply detergent. Start washing from the bottom and work
up. Allow the detergent to set 5-10 minutes. After wash-
ing, rinse from the top down.
Cleaning heavy dirt or material away with a hard stream
of clear water is recommended before using a cleaning
agent.
MAINTENANCE
Pump Lubrication
The pump on your CB Pressure Washer is a triplex ce-
ramic plunger pump. As the plungers move back, water
flows through the inlet valve into the manifold chamber.
Then, when the plungers move forward, the inlet valves
close and the discharge valves open to produce discharge
pressure.
Use only SAE 30 weight non-detergent oil; change oil
after first 50 hours of use. Thereafter, change oil every
three months or at 500 hour intervals. Oil level should be
checked through the use of the dipstick found on top of
the pump, or half way up on the oil gauge window. Oil
should be maintained at that level.
Unloader Valves
The unloader valve is connected directly to the discharge
port of the pump. Its purpose is to allow recirculation
back into the pump inlet when the trigger on the spray
gun is closed.
Nozzles
Each machine is equipped with one spray nozzle depend-
ing on the flow and pressure of that particular model.
Spray nozzles vary in bore size and angle of spray.When
ordering replacement nozzles, please specify size and
angle of nozzle. Nozzle size for each machine is located
on the serial plate.
Winterizing Procedure
Damage due to freezing is not covered by warranty. Use
the following cold weather procedures whenever the
washer must be stored or operated outdoors under freez-
ing conditions.
During winter months, when the temperature drops below
32°F, protecting your machine against freezing is neces-
sary. A blowout valve is available which can be screwed
on in place of the garden hose to blow water out of the
system.When compressed air is not available or imprac-
tical, siphon a small amount of antifreeze into the ma-
chine and siphon a 50/50 mixture of antifreeze into the
pump. Run the pump dry for a few seconds and discon-
nect all hoses to allow water to drain.
Low Pressure Diagnosis
Refer to Troubleshooting Chart for low pressure. If, by
referring to the chart, the trouble is found to be either the
unloader or the pump, your next step is to determine
whether in fact the unloader or the pump is the problem.
This can be done by eliminating the unloader from the
system and attaching the discharge hose directly to the
pump. If high pressure is developed in this manner the
pump is good, and the unloader needs to be repaired or
replaced.
CAUTION:When using this procedure to test compo-
nents, keep the spray gun open at all times.
