Check for Shipping Damage
Check the unit for any damage that may have occurred in
shipping. Notify the carrier immediately if there is any
damage.
Set Up
Connect the high pressure hose between the pump outlet
and the gun inlet. Both of these connections are made
with quick couplers.

if used.
Install the appropriate spray tip on the wand. See Install-
ing and Changing Spray Tips. If you are using a
sandblaster kit, see its separate manual for installation
instructions.

local plumbing code regarding cross–connection
to the water supply. If required, a backflow
preventer may be installed.
