air hose. The 1 in. hose set includes an adapter hose
between the gun and main hose. See the parts on
page 21.
Use the shortest length possible when spraying. In -
creasing the hose length decrease sprayer perfor -
mance. Do not use more than 75 ft. (23 m) of fluid
hose.
Removing and Installing the Hopper
