OPERATING INSTRUCTIONS

1. Perform pre-start maintenance inspection on all applicable systems prior to operating the machine. This is essential for the safe, effective and efficient operation. You will get optimum performance from your system ONLY if these instructions 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 off 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 NONDETERGENT OIL OR HYDRAULIC 68. 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 confirm 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 adjustment 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 effect, 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 off to relieve system of pressure.

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

Downstream Chemical Injection: Standard (Direct Drive Units) High Pressure Soap (Belt and Flange Driven Units) (Optional)
NOTE : Do not remove back flow preventer as chemical may flow back into potable water source. For standard chemical injection, 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. Note: for EK Pumps, the volume is preset and cannot be adjusted.
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.

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 washing fluid or Anti-Freeze, RATED FOR MINIMUM -40°C.
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.

GENERAL MAINTENANCE

Water Condition

Use a softener on your water system if local water is known to be high in mineral content. The advantages of soft water are very beneficial: prevents scale buildup in heater coil, cleans better with considerably less detergent, prevents streaking on painted surfaces and glass when rinsing.

MAINTENANCE CHECKLIST

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 accordingly—

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 and Hydraulic 68 for EK Pumps.
2. Change all other components on the pump as needed.

From pressure fittings| Fittings not tightened or taped, or cracked| Usually metal to metal fittings should be taped with Teflon tape or lock tight to provide a tight seal. (unless
From quick connects| Bad o-rings| If quick connect o-ring shows wear or damage, replace it.
From pump| Bad packing| If the seal leak is detected under the pump manifold, packing may be worn and in need of replacement.
From trigger gun| Bad rod o-ring| If o-rings show wear or damage, they may need replaced.
Stripped connectors| Physical damage may not be apparent, but unseen warping from freezing or extreme pressure can still cause leakage.
From nozzle| Weep gun (optional)| If a weep gun has been installed, check the gun valve seat to ensure it is functioning properly.
Damage gun valve ball or seat| Inspect trigger gun valve assembly for damage or ware to ball or seat. Lodged debris can stop valve from closing. Repair with kit or replace.
From unloader| Bad o-rings or seals| If quick connect o-ring shows wear, damage or improper seating.
From variable pressure Lance(option)| Bad o-rings at adjusting knob| Inspect o-rings for ware or damage and replace as necessary.
Unloader will not unload| Debris in unloader| Take bottom nut off unloader, identify ball, spring and seat. Clean out any debris and reassemble.
Sever leak on the outlet of unit| Check for leaks and repair.
From pressure relief valve| System over pressure| See pressure and flow diagnostics to find the cause of the excessive pressure and correct it.
Clogged nozzle| Spray pattern will be distorted if nozzle is clogged, clean out.
Trigger gun valve not working| If trigger gun valve action is not correct, repair or replace.
Excessive pressure spike| If water spurts from valve when trigger is released, check unloader adjustment. Pressure spike should be below the level where pressure relief valve is activated.
Wear or damage to ball or seal| Inspect ball and seal for damage and adjust as necessary.
Improper relief valve adjustment| Adjust valve properly.

FLUID SYSTEM DIAGNOSTICS – Trigger Gun/Spray Nozzle

gun valve piston rod and replace if necessary.
Missing metal insert in trigger gun (European style gun)| Inspect to assure insert is in place.
Blockage in system past gun| Check nozzle or spray accessory for blockage and clear it.
Excess pressure when trigger gun is released| Excessive pressure spikes| After unloader increases pressure to a maximum, further adjustment will only increase the pressure spikes. Re-adjust.
Flow not stopping when trigger gun released| Broken return spring on trigger gun| If trigger action is too loose, return spring may need replaced.
Debris in gun valve| Debris in gun valve can stop piston return. Clear debris.
Trigger action sticks| Keeper plug too tight| It may be possible to loosen plug slightly without leakage but it will likely need replaced.
Trigger gun leaks| Worn or bad o-ring| Check trigger gun o-rings for ware or damage and replace.
Stripped or loose connections| Physical damage may not be apparent but unseen warping from freezing or sever overpressure may still cause leaking.
No chemical| Chemical valve closed Black nozzle| Open chemical valve. If It chatters with no chemical delivery, air is being drawn from the upstream side of the pump. Check fittings, connections and ensure the inlet line is fully submerged into the chemical jug.
Chemical dried up in the injector| Inspect and clean as necessary.
Chemical foot strainer clogged| May be a strainer or check valve. Ensure that the ball is not stuck or clogged.
Chemical line kinked| Chemical line kinking or binding prevents chemical delivery.
Chemical line too long| An overly long chemical line can prevent the pump from drawing chemical into the system. Try installing a shorter line.
Chemical too dilute| Verify chemical strength.
No adjustment for low pressure| Downstream injectors only – Low pressure is required for most injectors to draw chemical. If no adjuster exists it may need low pressure spray nozzle installed on the lance.
Incorrect injector orifice| If not properly sized for the systems rated output, chemical delivery problems will result. Check serial plate for specs.
Excessive chemical| Valve improperly adjusted, check knob on injector| To properly adjust, a chemical flow meter may be used to precisely measure chemical flow.
Chemical dilution to strong| Verify chemical strength.
Spray pattern irregular| Clogged nozzle| Spray pattern will be distorted if nozzle is clogged.
Volume proper, pressure low| Nozzle to large| Ensure that the nozzle is sized properly sized for the system
Internal nozzle wear| A loss of pressure may result form gradual nozzle wear. Replace a nozzle of correct size.
Pressure proper, volume low| Clogged nozzle| Spray pattern will be distorted if nozzle is clogged. Check nozzle for clogging if the unit has a pressure unloader.

BOILER SYSTEM DIAGNOSTICS – Boiler Controls

used to check continuity through controls and pinpoint the problem areas.
Solenoid coil does not energize| Bad connection to solenoid coil| Electrical connections to solenoid valve coil should be tight and not corroded.
Coil bad| Check to see if fuel solenoid will energize when the proper voltage is applied. Solenoid may need replacing.
Boiler control not activating properly| If coil energizes when proper voltage is applied, check boiler controls.
Solenoid coil energizes| Problem occurring else where| If solenoid valve coil energizes when the cleaner is operating in hot water the problem is elsewhere. Check the air/fuel delivery.

BOILER SYSTEM DIAGNOSTICS – Pressure Switch

through the boiler side of the switch. If not the switch may not need replaced.
Switch improperly wired| Switch may be improperly wired for its function.
Switch bad| If wiring is proper and still no current flow when activated, switch may need replacement.
Switch does not activate| Plunger fouled or stuck| Check pressure plunger to see if it will travel freely. If not, the passage may need cleared.
Plunger not moving far enough| Check to see if the plunger is traveling far enough to depress the microswitch. Adjust if necessary.
Switch activated manually| Current not flowing through switch| If switch activates manually but boiler does not fire, current may not be flowing through. The switch may need replacing.
Microswitch not properly adjusted| Microswitch may need readjustment so plunger can trip in.
Switch bad| Replace switch with another one.
Problem elsewhere in the system.| If switch works manually and current is flowing properly, the problem is elsewhere. Try other boiler diagnostics.

BOILER SYSTEM DIAGNOSTICS – Vacuum Switch – Optional

improper diaphragm movement is detected.
Low water flow| Correct problems related to inadequate water flow.
Air leak in or punctured diaphragm| Replace vacuum switch if diaphragm shows an air leak or hole.
Switch shows continuity when activated| Problem elsewhere in system| If vacuum switch works properly, continue with other boiler control diagnostics.
Switch does not shows continuity when activated| Switch contact bad| Replace switch with another one.

BOILER SYSTEM DIAGNOSTICS – Flow Switch – Optional

unstick it.
Reed switch misadjusted| To adjust it for the flow the system is producing, loosen the reed switch and move it in its
Magnet is bad| If reed switch activated the boiler when tested with a hand held magnet, the internal magnet may
Reed switch does not activate when tested with external magnet| Reed switch is bad| If reed switch does not activated the boiler when tested with a hand held magnet, the reed switch may need replacement.
Problem elsewhere in system| See diagnostics listed above.

BOILER SYSTEM DIAGNOSTICS – Thermostat

ensure connections are not loose or corroded.
Boiler fires when thermostat jumped, but will not fire with thermostat in circuit| Thermostat bad| Replace Thermostat.
Boiler will not fire when thermostat jumped| Problem elsewhere in system| Continue with boiler control diagnostics. If boiler still does not fire, the thermostat may need replaced.

BOILER SYSTEM DIAGNOSTICS – High Temperature Limit

connections to high temperature limit switch to ensure that they are not loose or corroded.
Problem elsewhere in system| If there is continuity through the switch but the boiler still does not fire, there is a problem elsewhere in the system. Continue with boiler control diagnostics.
No continuity through switch| Switch bad| Replace switch.
