Pre-Operation Check

Read machine safety warnings
Pump oil SAE 10W-40 (non-foaming oil)
Cold water supply (1gpm over machines rating-5/8″ 20 psi)
Proper power supply and circuit protection
Hose, wand, nozzles (nozzle sizes per serial plate)
Water filter (intact, non restrictive)
Read operation instructions
This machine must be protected from the elements/freezing.

Set-up Procedures
This machine is intended for indoor use. Machine must be stored indoors when not in use.

Attach a minimum 5/8″ garden hose to inlet connector. Minimum flow should be 1 gpm over the flow rate of the pressure washer.
Attach high pressure hose to discharge nipple using quick coupler. Lock coupler securely into place by pulling back coupler collar and inserting it onto dis-charge nipple, then pushing collar forward to lock in place.
Attach wand to spray gun using Teflon tape on threads to prevent leakage.
Attach connector on discharge hose to spray gun using Teflon tape on threads.
Remove oil plug on top of pressure washer pump and replace with dipstick supplied. (This may be installed from the factory.
Check oil level on oil dipstick on top of pump. Oil should be visible one half way up sight glass (10W-40 non-foaming).

Operating Instructions

Read safety and preventative maintenance instructions before starting machine.
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.
Push the pump switch on.
Turn the variable pressure control handle clockwise to increase pressure.
To apply detergent read “How to Use The Detergent Injector.”

Shut Down Procedures

Rinse with clean water to remove any soap residue, by placing detergent hose into fresh water bucket and operating injector as described below.
Release the trigger on the spray gun. Turn the switch off if the machine is going to be left unat-tended. (Time delay only).
Turn off water supply.
Open spray gun to relieve remaining pressure.
Remove water supply hose.

Selection of high or low pressure is accomplished by turning the handle.
NOTE: High pressure nozzle must be inserted at end of wand to obtain high pressure. to apply soap read operator’s manual.

Component Identification

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 the detergent injector kit.

Start machine as outlined in Operating Instructions.
Place detergent pick-up tube into container of detergent solution.
Turn the pressure control handle on the variable pressure wand counterclockwise to low pressure.
Open trigger on spray gun. Water detergent ratio is approximately 15 to 1.
NOTE: Soap will not siphon under high pressure.
When you finish with the detergents, rinse by simply turning the variable pressure control handle clockwise to high pressure.
After use, place siphon strainer into container of clear water and follow steps 3 and 4 to avoid detergent deposit build-up.

General Washing 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 a few minutes. After washing, 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 1700 Series pressure washer is a triplex ceramic 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 10W-40 weight (non-foaming oil); change oil after first 50 hours of use. Thereafter, change oil every year 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 four spray nozzles depending 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.

Storage

CAUTION: Always store your pressure washer in a location where the temperature will not fall below 32° F (0° C). The pump in this machine is susceptible to permanent damage if frozen.

FREEZE DAMAGE IS NOT COVERED
BY WARRANTY.
LES DOMMAGES DUS AU GEL NE SONT PAS COUVERTS PAR LA GARANTIE.

Winterizing Procedure
Use the following cold weather procedures whenever the washer must be stored or operated outdoors under freezing conditions.
During winter months, when the temperature drops below 32°F, protecting your machine against freezing is necessary. 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 avail-able or impractical, siphon a small amount of antifreeze into the machine and siphon a 50/50 mixture of anti-freeze into the pump. Run the pump dry for a few seconds and disconnect 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 components, keep the spray gun open at all times.
