Shipping Damage
Check pressure washer for shipping damage. Notify the 
carrier immediately
 if there is any damage.
Connecting High-Pressure Hose and Gun
Connect high-pressure hose between pump outlet and 
gun inlet. Both of these connections are made with quick 
couplers.
Installing Spray Tip
Install spray tip on wand. (Installing and Changing Spray 
Tips, page.) If you are using a Sandblasting Kit, see its 
separate manual for installation instructions.
Connect to Water Supply
Connect hose from water supply to the garden hose 
inlet on the pressure washer. 
Up to 100 ft (30 m) of 3/8 in. high-pressure hose

The supply hose should not be longer than 50 
ft (15 m) in length. 
Inside diameter of hose should measure at 
least a 3/4 in. (19 mm).
CAUTION
Before you connect garden hose to pressure 
washer, check your local plumbing code regarding 
cross-connection to the water supply. If required, 
install a backflow preventer.
If the inlet water pressure is over 60 psi (4.1 bar, 41 
MPa), a regulating water valve must be installed at 
the garden hose connection.
Do not exceed 160° F (70° C) inlet water tempera-
ture.
The water source must have a minimum flow rate 
equal to that of the pressure washer.
