COMPONENT IDENTIFICATION

• Pump — Develops high pressure.
• Spray Gun — Controls the application of water and detergent onto cleaning surface with trigger device. Includes safety latch.
• Wand — Must be connected to the spray gun.
• Unloader — Safety device that relieves pressure when spray gun trigger is closed.
• High Pressure Hose — Connect one end to water pump discharge nipple and the other end to spray gun.
• Pump Protector — Cycles fresh cool water through pump when recirculating water reaches 140°F.
• GFCI — Ground fault circuit interrupter trips when voltage leaks to ground.
  Note: If trigger on spray gun is released for more than 1-2 minutes, water will leak from valve. Warm water will discharge from pump protector onto floor. This system prevents internal pump damage.

ASSEMBLY INSTRUCTIONS

• STEP 1: Attach the high pressure hose to the spray gun using Teflon tape on hose threads.

• STEP 2: Attach wand to spray gun using Teflon tape on wand threads.

• STEP 3: Pull spring-loaded collar of the wand coupler back to insert your choice of pressure nozzle.
  

• STEP 4: Release the coupler collar and push the nozzle until the collar clicks. Pull the nozzle to make sure it is seated properly.

• STEP 5: Connect the high pressure hose to the discharge nipple. Push coupler collar forward until secure.

• STEP 6: Connect garden hose to the cold water source.
  

• STEP 7: Check inlets filters, re-move debris, then connect the garden hose to pump water inlet.
  CAUTION: Do not run the pump without water or pump damage will result.

OPERATING INSTRUCTIONS

• STEP 1: Connect garden hose to the cold water source and turn water on completely. Never use hot water.

• STEP 2: Trigger the spray gun to eliminate trapped air then wait for a steady flow of water to emerge from the spray nozzle.

• STEP 3: Connect to appropriate power supply. Push reset button on GFCI.
  

• STEP 4: Turn machine on by turning switch at top of motor.
  WARNING! Never replace nozzles without engaging the safety latch on the spray gun trigger.
  

The four color-coded quick connect nozzles provide a wide array of spray widths from 15° to 40° and are easily accessible when placed in the convenient rubber nozzle holder, which is provided on the front of the machine.
NOTE: For a more gentle rinse, select the white 40° or green 25° nozzle. To scour the surface, select the yellow 15° nozzle. To apply detergent select the black nozzle.

DETERGENTS AND GENERAL OPERATING TECHNIQUES

WARNING: Some detergents may be harmful if inhaled or ingested, causing severe nau-sea, fainting or poisoning. The harmful elements may cause property damage or severe injury.

• STEP 1: Connect detergent injector to discharge nipple on machine. Connect high pressure hose to injector with quick coupler. (Check to make sure locking coupler sleeves are in proper position before applying water pressure).

• STEP 2: Use detergent designed specifically for pressure washers. Household detergents could damage the pump. Prepare deter-gent solution as required by the manufacturer. Fill a container with pressure washer detergent. Place the filter end of detergent suction tube into the detergent container.

• STEP 3: With safety latch on spray gun engaged, secure black detergent nozzle into quick coupler. NOTE: Detergent cannot be applied using a pressure nozzle.

• STEP 4: With the motor running, pull trigger to operate machine. Liquid detergent is drawn into the machine and mixed with water. Apply detergent to work area. Do not allow detergent to dry on surface.

IMPORTANT: You must flush the detergent injection system after each use by placing the suction tube into a bucket of clean water, then run the pressure washer in low pressure for 1-2 minutes.

THERMAL PUMP PROTECTION

If you run the motor on your pressure washer for 1-2 minutes without pressing the trigger on the spray gun, circulating water in the pump can reach high temperatures. When the water reaches this temperature, the pump protector engages and cools the pump by dis-charging the warm water onto the ground. This thermal device prevents internal damage to the pump.

CLEANING TIPS

Pre-rinse cleaning surface with fresh water. Place de-tergent suction tube directly into cleaning solution and apply to surface at low pressure (for best results, limit your work area to sections approximately 6 feet square and always apply detergent from bottom to top). Allow detergent to remain on surface 1-3 minutes. Do not allow detergent to dry on surface. If surface appears to be drying, simply wet down surface with fresh water. If needed, use brush to remove stubborn dirt. Rinse at high pressure from top to bottom in an even sweeping motion keeping the spray nozzle approximately 1 foot from cleaning surface. Use overlapping strokes as you clean and rinse any surface. For best surface cleaning action spray at a slight angle.
Recommendations:

• Before cleaning any surface, an inconspicuous area should be cleaned to test spray pattern and distance for maximum cleaning results.
• If painted surfaces are peeling or chipping, use extreme caution as pressure washer may remove the loose paint from the surface.
• Keep the spray nozzle a safe distance from the surface you plan to clean. High pressure wash a small area, then check the surface for damage. If no damage is found, continue to pressure washing.

CAUTION – Never use:

• Bleach, chlorine products, other corrosive chemicals
• Liquids containing solvents (i.e., paint thinners, gasoline, oils)
• Tri-sodium phosphate products
• Ammonia products
• Acid-based products

These chemicals will harm the machine and will dam-age the surface being cleaned.

RINSING

It will take a few seconds for the detergent to clear. Apply safety latch to spray gun. Remove black soap nozzle from the quick coupler. Select and install the desired high pressure nozzle. NOTE: You can also stop detergent from flowing by simply removing detergent siphon tube from bottle.

SHUTTING DOWN AND CLEAN-UP

• STEP 1: Remove deter-gent suction tube from container and insert into one gallon of fresh water. Slide nozzle forward for low pressure or use black detergent nozzle. Pull trigger on spray gun and siphon fresh clean water for one minute.

• STEP 2: Turn off machine by turning switch to “OFF” switch.

• STEP 3: Turn off water supply.

• STEP 4: Press trigger to release water pressure.
  

• STEP 5: Disconnect the garden hose from the water inlet on the machine.

• STEP 6: Disconnect the high pressure hose from the discharge nipple.

• STEP 7: Engage the spray gun safety lock.
  

STORAGE

Pump 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 B Y WARRANTY.
If you must store your pressure washer in a location where the temperature is below 32°F, you can minimize the chance of damage to your machine by draining your machine as follows:

1. Stop the pressure washer and detach supply hose and high pressure hose. Squeeze trigger of spray gun to drain all water from the wand and hose.
2. Restart pressure washer and let it run briefly (about 5 seconds) until water no longer discharges from the high pressure outlet.
