This air–powered ram extruder forces high viscosity flu-
ids into the intake valve of the fluid pump. Wiper rings and
other accessory equipment for use with this ram are
listed in the ACCESSORIES section.
NOTE: To convert the ram from air to hydraulic opera-
tion, install piston kit 220–501 (see page 18).
Contact your Graco representative for details.
Locating the Ram
NOTE: Refer to the Dimensional Drawing on page 19 for
ram mounting and clearance dimensions.
1. Select a convenient location for the equipment.
Check that there is sufficient overhead clearance for
the pump and ram when the ram is in the fully raised
position. Make sure the air regulators for the pump
and ram are fully accessible.
2. Level the base of the ram, using metal shims.
3. Using the holes in the base as a guide, drill holes for
1/2 in. (13 mm) anchors. Bolt the ram to the floor with
anchors which are long enough to prevent the unit
from tipping. Refer to the Dimensional Drawing on
page 19.
4. Mount the pump on the ram, following the applicable
procedure on page 5 or 6.

Installing Accessories and Connecting Air
Lines
1. Install an air line filter (A) on the air supply line to re-
move harmful moisture and contaminants from the
compressed air supply.
2. Install a bleed–type master air valve (B) downstream
from the pump air regulator (C).
WARNING
The bleed–type master air valve (B) is required in
your system to relieve air trapped between this
valve and the pump after the pump air regulator is
closed. Trapped air can cause the pump to cycle
unexpectedly, which could result in serious bodily
injury, including splashing in the eyes or on the skin
and injury from moving parts.
3. Install an air manifold (D) on the mounting bracket
(66). Connect a suitable air hose (E) between an out-
let port of the air manifold and the air inlet of the ram
air regulator (F).
4. Install a second bleed–valve (G) upstream from all
accessories, to isolate the accessories for servicing.
Connect the main air supply line (H) to the manifold
(D).
