Installation
Grounding
. 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
Typical air requirements for continuous use at 400 rpm
and 100 psi (0.7 MPa, 7 bar) inlet pressure:
•
high viscosity air motor -- 22 scfm (0.62 m
3
/min)
•
low viscosity air motor -- 12 scfm (0.34 m
3
/min)
Air Line Accessories
Install the following accessories in the order shown in
F
. 2, using adapters as necessary.
Bleed-type master air valve (A):
required in your
system to relieve air trapped between it and the air
motor when the valve is closed.
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
lubrication. 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
, page 9. A 3/8 in. npt air line
lubricator, Part 214847, is available from Graco.

The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.

To prevent personal injury from air motor component
rupture, do not exceed 100 psi (0.7 MPa, 7 bar)
maximum air working pressure.
