DETERGENTS AND GENERAL OPERATING TECHNIQUES
WARNING
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.
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).
Filter
Discharge
Nipple
Detergent
Injector
Quick
Coupler
STEP 2: Use detergent designed specifically for pressure wash ers. 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 cou pler. 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 tempera tures. 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 detergent 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
On/Off
Switch
STEP 1: Remove detergent suction tube from container and insert into one gallon of fresh water.

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.

STORAGE
Pump Storage
CAUTION
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 W A R -
RANTY.
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.
