Installation
NOTE: Reference numbers and letters in parentheses in the text refer to the callouts in the figures and in the parts drawing.
Grounding
The equipment must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for the electrical current due to static build up or in the event of a short circuit.
See FIG. 1. Loosen the grounding screw (GS). Insert one end of a 12 ga. minimum ground wire behind the grounding screw and tighten the screw securely.
Connect ground clamp to a true earth ground. A ground wire and clamp, Part 238909, is available from Graco.

Air Requirements
To help prevent component rupture, do not exceed 100 psi (0.7 MPa, 7 bar) maximum air working pressure.
Typical air requirements for continuous use at 400 rpm and 100 psi (0.7 MPa, 7 bar) inlet pressure:
•low viscosity air motor
•high viscosity air motor
Air Line Accessories
Install the following accessories in the order shown in FIG. 2, using adapters as necessary.
Air filter (B): removes harmful dirt and moisture from the compressed air supply. Order part 106148 for 3/8 npt or 106149 for 1/2 npt.
Air regulator and gauge (C): to control air motor and agitator speed.
Air line lubricator (D): Downstream from the filter, install an air line lubricator for automatic air motor lubri- cation. Set the lubricator feed rate at 1 drop of oil per minute for high speed or continuous duty usage. Do not overfeed oil or exhaust air may become contaminated. To manually lubricate the air motor, see Lubricate the Air Motor, page 6. A 3/8 in. npt air line lubricator, Part 214847, is available from Graco.
NOTICE
Not lubricating the air motor will cause air motor failure.
