CONNECTING THE GARDEN HOSE TO THE
PRESSURE WASHER
See Figure 12.
CAUTION:
Always observe all local regulations when connnecting
hoses to the water main. Some areas have restrictions
against connecting directly to public drinking water sup-
ply to prevent the feedback of chemicals into the drinking
water supply. Direct connection through a receiver tank
or backflow preventer is usually permitted.
The water supply must come from a water main. NEVER use
hot water or water from pools, lakes, etc. Before connecting
the garden hose to the pressure washer:
 Run water through the hose for 30 seconds to clean any
debris from the hose.
 Inspect the screen in the water intake.
 If the screen is damaged, do not use the machine until
the screen has been replaced.
 If the screen is dirty, clean it before connecting the garden
hose to the machine.
To connect the garden hose to the machine:
 Uncoil the garden hose.
NOTE: There must be a minimum of 10 feet of unrestricted
hose between the pressure washer intake and the hose
faucet or shut off valve (such as a "Y" shut off connector).
 With the hose faucet turned completely off, attach the end of
the garden hose to the pump's water intake. Tighten by hand.
ASSEMBLY
CONNECTING THE HIGH PRESSURE HOSE TO
THE PUMP
See Figure 13.
After the high pressure hose has been uncoiled and attached
to the spray wand:
 Pull back and hold the collar on the pump outlet. Insert
the inlet coupler on the high pressure hose into the collar.
 Release the collar and push until it locks into place. Pull
on the hose to be certain it is properly secured.
 Pull on the hose to be certain it is properly secured.
CAUTION:
Do not run the pressure washer pump without water sup-
ply connected and turned on, as this may damage the
high pressure seals and decrease pump life. Completely
unwind the hose from its reel or coil and make sure the
hose is not being restricted by tires, rocks, or any other
objects that may lessen or prevent water flow to the
pressure washer.
