bly by inserting the stem and tightening the
threaded collar.

push the hose retaining clip fully downward which
will secure the hose to the pressure washer.

port by using the quick connect coupler supplied
with your unit. Make sure the screen faces the
water hose.
4. Turn on water supply, then release trigger safety,
pull trigger to remove any trapped air in the system
(about 15 seconds). Verify that there are no water
leaks.
5. Verify that the pressure washer switch is in the "Off"

Protected outlet. (Push reset on G.F.C.I.).

OPERATION
1. For high pressure cleaning, attach adjustable spray
wand to middle extension wand (see #6 in Start-
up). Spray pattern can be adjusted from narrow
angle to wide angle by rotating the end of the
wand. Narrow spray patterns are ideal for stubborn
areas whereas wide spray patterns increase overall
coverage.
2. For applying detergents, attach detergent dispenser
to middle extension wand (see #6 in set-up). The
cup should be oriented downward. When using
detergents, it is best to give them time to work (3
to 5 minutes) before high pressure rinse.
SHUT-DOWN
1. Turn off the water supply and disconnect quick
connect coupler.
2. Pull the trigger for 2 to 4 seconds to remove
remaining water from the hose and pump.
NOTE: (This should be done quickly). Unit will
continue to run without the water connected to
your pressure washer.
3. Turn switch off and unplug.
Operating unit with water supply shut off (without flow of water) will result in equipment damage.
During shut-down, entire system including pump, hose and wand will remain under pressure.
Do not attempt to remove hose/gun until pressure is relieved.
