Attach the turbo nozzle extension to spray gun.
Tighten by hand.
\
4. Disengage trigger lock on spray gun trigger.
5. Always start the turbo nozzle at a distance,
gradually getting closer to the surface until you get
the cleaning force you want.
NOTE: Detergent cannot be applied with turbo nozzle.
Applying Detergent with Adjustable Nozzle
iMPORTANT: Use detergents designed specifically for
pressure washers. Household detergents could
damage the pump.
CAUTION
• Starting the engine without all the hoses connected and
without the water turned ON will damage the pump.
• Damage to equipment resulting from failure to follow this
instruction will void warranty.
To apply detergent, follow these steps:
1. Review use of adjustable nozzle.
2. Prepare detergent solution as required by job.
3. Place filter end of detergent siphoning tube into
detergent container.
I CAUTION
1
• When inserting
the filter into
a detergent solution bottle,
route the tube so as to
keep
it from
inadvertently
contacting
the hot muffler.
4. Slide adjustable nozzle forward to low pressure
mode. Detergent cannot be applied with nozzle in
high pressure position.
5. Make sure garden hose is connected to water
inlet. Check that high pressure hose is connected
to spray gun and pump. Start engine.
6. Apply detergent to a dry surface, starting from
bottom and working up.
7. Allow detergent to "soak in" for 3-5 minutes before
rinsing. Reapply as needed to prevent surface
from drying.
8. For washing, start at lower portion of area to be
washed and work upward, using long, even,
overlapping strokes.
iMPORTANT: You must flush the chemical injection
system after each use by placing the filter into a clean
bucket of water and running the pressure washer in
low pressure for 1-2 minutes.
Pressure Washer Rinsing
For Rinsing:
1. Slide nozzle backward to high pressure, press
trigger and wait for detergent to clear.
NOTE: You can also stop detergent flow by removing
detergent siphoning tube from container.
2. Keep spray gun a safe distance from area you
plan to spray.
WARNING
,
,
Keep spray nozzle between 8 to 24 inches away from
cleaning surface.
Operate this unit on a stable surface.
Be extremely careful if you must use the pressure
washer from a ladder, scaffolding or any other relatively
unstable location.
Firmly grasp spray gun with both hands when using high
pressure spray to avoid injury when gun kicks back.
Apply a high pressure spray to a small area, then
check surface for damage. If no damage is found,
it is okay to continue cleaning.
Start at top of area to be rinsed, working down
with same overlapping strokes as you used for
washing and applying detergent.
Cleaning Detergent Siphoning Tube
If you used the detergent siphoning tube, you must
flush it with clean water before stopping the engine.
1. Place detergent siphoning tube/filter in a bucket
full of clean water.
2. Engage trigger lock on spray gun.
3. Slide adjustable nozzle forward to low pressure
position.
4. Flush for 1-2 minutes.
5. Shut off engine.
6. ALWAYS point gun in a safe direction and
squeeze spray gun trigger to release retained high
water pressure.
iMPORTANT: Spray gun traps high water pressure,
even when engine is stopped and water is disconnected.
Automatic Cool Down System
(Thermal Relief)
If you run the engine on your pressure washer for
3-5 minutes without pressing the trigger on the spray
gun, circulating water in the pump can reach
temperatures above 125°F (51°C). The system
engages to cool the pump by discharging the warm
water onto the ground.
