washed and work upward, using long, even,
overlapping strokes.
Pressure Washer Rinsing
_ ARNING: Be extremely careful if you use the
pressure washer from a ladder, scaffolding or
any other relatively unstable location. Pressure
in a running washer builds as you climb. When
you press the trigger, the recoil from the initial
spray could force you to fall. The high pressure
spray could also force you to fall if you are too
close to the cleaning surface.
For Rinsing:
• Slide the nozzle backward to high pressure, press
the trigger and wait for the detergent to clear.
NOTE:Youcanalsostopdetergentflowbyremoving

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 between 140-145°F. The automatic cool
down system engages at this temperature and cools
the pump by discharging the warm water onto the
ground, preventing internal pump damage.
How to Use the Hose Reel
Your pressure washer is equipped with a hose reel
that is designed to store your hose when unit is not in
use. These instructions are for short term storage
only. For long term storage see "Storage" on page 16.
After each use:
• Disconnect hose from gun and high pressure outlet
on pump.
• Drain water from hose.
• Slide one end of the hose into the hole on the hose
reel. Turn the hose reel clockwise with the handle
to coil the hose onto the reel.
• Push the other end of the hose into the clip on the
side of your unit.
IMPORTANT: Do Not use your pressure washer with
the hose coiled onto the hose reel. The hose reel is for
storage purposes only.

becomes clogged, as follows:
In-line Filter
Nozzle extension
O-ring
.
Detach gun and nozzle extension from high
pressure hose. Detach nozzle extension from gun
and remove o-ring and screen from nozzle
extension. Flush the screen, gun, and nozzle
extension with clean water to clear debris.
.
If the screen is damaged, the o-ring kit contains a
replacement in-line filter screen and an o-ring. If
undamaged, reuse screen.
.
Place the in-line filter screen into the threaded end
of the nozzle extension. Direction does not matter.
