Glossary of Terms
Auto Start/Stop – Unit will automatically start when the trigger is pulled, and it will stop the motor on time delay after the
trigger has been released in order to prevent the pump from bypassing and overheating.
PSI – Pounds per square inch. Pressure washers are designed and rated to operate at a specific PSI. Operating at pressures
exceeding the maximum rating could result in damage to the unit and/or SEVERE PERSONAL INJURY.
GPM – Gallons per minute. The orifice on the pressure wand assembly has been selected to deliver up to the maximum GPM
for your machine.
Pressure Wand Assembly – This refers to the gun, wand, and nozzle.
Pump – The pump moves the water through the system and delivers it to the pressure wand assembly.
Unloader Valve – Is a valve located at the head of the pump for unloading water back into the bypass when the trigger gun
is shut o. It also reduces the load on pump when gun is o.
Pump Oil – The oil used within the pump to lubricate its operation. It is Important to use only SAE 30 W Non Detergent (for
GP Pumps).
Back Flow Preventer – Device to prevent flow backwards into potable water supply.
Maximum Working Pressure - Each machine is equipped with a safety pressure relief valve which prevents over pressur-
ization of the high pressure system. It is an important safety device and must not be tampered with in any way.
Pressure Switch - A pressure switch is used to control the motor for the auto stop/start feature.
Flow Switch – A flow switch is installed on the outlet of the high pressure pump and will shut o the pump and motor in the
absence of water flow as well as turning it back on when flow is detected (by squeezing the trigger).

Operating Instructions
1. Perform pre-start maintenance inspection on all applicable systems prior to operating the machine. This is essential
for the safe, eective and eicient operation. You will get optimum performance from your system ONLY if these instruc-
tions and inspections are followed. Any indication that the pressure washing system was not operated and maintained
according to these instructions may cancel the manufacturers’ warranty.
Controls – Make sure all controls turned to the o position.
Pump oil level - Level the pressure washer. Be sure oil level in the pump is correct on dip stick. If the level is low, add the
correct oil to the proper level. USE ONLY SAE 30 W NON-DETERGENT OIL. DO NOT OVER FILL.
Visually inspect all electrical components to assure they are in good condition, showing no signs of exposure, breakage
or splicing.
Visually inspect all hoses, nozzles and guns to assure they are in good condition. If replacements are necessary they
must be rated to withstand the machines operating pressure and temperatures.
2. Attach high-pressure hose to water outlet quick connector. Attach the other end of high pressure hose (with quick
coupler) to spray gun. Ensure that quick disconnect connections are tightly locked together. Apply a sharp pull on hose to
confirm they are secured.
Attach wand nozzle specific to task requirements (i.e. chemical or pressure wash)
Quick Coupling Operation – Pull back sleeve end and insert male end into nozzle quick coupler, release sleeve and con-
firm connection by pulling on nozzle.
3. Attach water source to water inlet located on pump. The water source must be attached with a good quality standard
garden type hose (1/2” minimum is required). Connect male fitting into the female pump inlet fitting. Make sure that the
inlet screen/filter is intact and fitted correctly.
Turn on water source. WATER MUST BE IN SUFFICIENT SUPPLY, AND PRESSURE MUST BE BETWEEN 20 – 60 PSI
TO ENSURE PROPER AND SAFE OPERATION. Specific attention should be given if using a well water supply.
Ensure water is flowing from end nozzle with trigger gun pulled. Deplete system of all air.
4. Start electric motor. Turn PUMP switch to “ON’”. PUMP switch is located on the frame beside the motor, or for auto
stop/start systems, PUMP switch is located on the electrical box.
5. Pressure adjustment - The pressure regulator (unloader) is located on the pump (see diagram). It controls pressure
being generated by the pressure washer. This regulator may be adjusted to the desired pressure by turning the adjust-
ment knob. Turning the adjustment knob clockwise will increase the pressure. NEVER OPERATE SYSTEM AT A HIGHER
PSI THAN THE MAXIMUM RATING. This machine has been adjusted to operate at a specific maximum pressure as per
the machine specifications. Pressure may be reduced for lighter use by turning the Pressure Regulator/Unloader counter
clockwise. If continuing to turn the unloader clockwise does not increase the pressure, then this implies the maximum has
been reached for the system. Any further turning of the unloader will cause the pressure to spike when the wand trigger is
released, resulting in possible damage to the machine. To avoid this eect, loosen the unloader (counter-clockwise) until
the pressure just starts to drop (see pump head pressure gauge) and until it no longer exceeds the maximum pressure
rating for the machine.
6. You are now ready to start the cleaning operation - Pull trigger on the pressure wand assembly to start cleaning.
To stop the pressurized water, release the trigger. DO NOT LEAVE UNIT RUNNING WHEN NOT IN USE.
7. To stop Operation. Turn PUMP switch to ‘OFF’. Squeeze and release trigger after shutting o to relieve system of pres-
sure.
8. Prior to storage – Inspect pressure washer for any damage or required maintenance. If your machine is to be exposed
to cold weather, please refer to winter pump instructions found in this manual. If possible, do not allow unit to remain
outside in the elements.
9. Warning – If unit is left running while not in use, pump damage may occur. Do not leave unit running while not in use!

Chemical Application
NOTE: Do not remove back flow preventer as chemical may flow back into potable water source. For standard chemical injec-
tion, ensure the black nozzle is properly fitted at the end of the wand. The chemical injector will not function if this nozzle is not
fitted.
1. Chemical preparation – Select detergent/chemical that best suits your cleaning task. Prepare dilution according to the
manufacturer’s instructions. The volume of chemical being used may be adjusted at valve located on the chemical injector.
2. Insert the intake hose, located on the chemical injector at the pump, into the chemical being used.
3. Fit black nozzle on the standard wand, or for the dual wand, turn adjustment knob on, and adjust for required flow rate.
For high pressure soap systems, the black nozzle is not needed; use one of the other wand nozzles.
4. To apply chemical, engage trigger on pressure wand assembly. Turn chemical injector’s nipple to adjust flow. For the high
pressure soap systems, open ball valve and engage trigger.
5. Chemical can now be applied through pressure wand assembly. It will take 5 – 15 seconds for chemical to travel to spray
nozzle. The volume of chemical being used may be adjusted at the chemical injector.
6. For best results apply chemical from bottom to top, and allow for proper penetration time prior to rinsing. Do not allow
chemical to dry. Rinse from bottom to top and then top to bottom.

Maintenance
Daily
1. Check pump oil for proper level and adjust accordingly.
2. Examine the quality of the oil.
3. Check pump for oil and/or water leaks.
4. Inspect and clean inlet filters.
Weekly
1. Examine all fittings, components, hoses, connections, and nozzles for damages, loose parts, or leaks (Replace accord-
ingly).
Recommendation for Oil Changes and Component Replacement
1. Change the oil in the pump after the first 50 hours and every 500 hours after the initial oil change. Use SAE 30 W
Non-Detergent for GP Pumps.
2. Change all other components on the pump as needed.
Water Condition
Use a softener on your water system if local water is known to be high in mineral content. This prevents scale buildup in
heater coil, cleans better with considerably less detergent, prevents streaking on painted surfaces and glass when rinsing.
Winter Pump Protection
The following procedure MUST be used when the pressure washing unit is stored at temperatures below freezing.
1. All water must be drained or blown (via compressed air) from system. Connect a short piece of male fitted ½” garden
type hose on to the female inlet on the pump.
2. Place the open end of the hose into a wide mouthed container of full strength, winter rated, vehicle windshield wash-
ing fluid or Anti-Freeze, RATED FOR MINIMUM -40°F.
3. Connect the pressure wand assembly.
4. Start the pump and engage trigger on the pressure gun. Operate the system until the fluid runs the same color as the
windshield washing fluid. Your machine is now prepared for storage.
5. Disconnect fluid supply, blow out with compressed air, and cap end.
