Assembly
WARNING
Check and test completed assembly
Check assembly to assure the sprayer is properly assembled and in safe
working condition:
a) Check that the gun clip screws are tight, hose clamps are secure, and
bolts/nuts are properly fastened.
b) While it is unlikely that factory assembled components become loose, they
should also be checked to make sure they are tight.
Test the system for leaks with water:
a) Fill the tank with water.
b) Connect the remote switch to the pump power cord and turn the remote
switch ON. The pump is an "on demand" pump. When turned on, the
pump will prime itself, and then turn off. When the gun trigger is
squeezed, the pump will automatically start.
c) Operate the spray gun by squeezing the gun trigger.
d) Check for leaks throughout the system. If a leak is detected, fix the leak and
re-test the system with water until no leaks are detected.
