d. Install supplied hose clamp around the air motor

bracket and funnel base then tighten.

3. Insert 1.3 in. (33 mm) OD clear vacuum transfer

hose (G2) into vacuum transfer funnel (G3) inlet and

secure with supplied hose clamp. See F

. 7.

4. Connect the long supplied 3/8 in. OD air line (G4) to

the 3/8 in. push-to-connect fitting on the air line from

the system. See F

. 7.

NOTE: In the following steps, when routing the vacuum

transfer hose, ensure there are no tight coils, turns, or

dips in the vacuum hose. These will inhibit optimal func-

tioning of the vacuum transfer system.

NOTE: Maximum vacuum hose length is 30 ft (9.1 m).

Use horizontal hose routing as much as possible. The

vacuum hose must not rise more than 10 ft (3.0 m),

measured from the vacuum inlet. Any vertical rise will

lower the maximum flow rate of the vacuum transfer

system.

5. Route the 1.3 in. (33 mm) OD clear vacuum transfer

hose from the system to the adhesive pellets con-

tainer location.

6. Apply pipe sealant to threads then attach steel

shaker tube (G) to shaker head (G1). See F

. 8.

7. Attach 1.3 in. (33 mm) clear vacuum transfer hose

(G2) to steel shaker tube (G) and secure with sup-

plied hose clamp. See F

. 8.

8. Route the 3/8 in. OD air line (G4) alongside the

1.3 in. (33 mm) clear vacuum transfer hose (G2)

and secure at multiple points with the supplied zip

ties (G5). See F

. 8.

9. If desired, secure the 1.3 in. (33 mm) clear vacuum

transfer tube and 3/8 in. OD air line with zip ties to a

supporting structure at various points in the routing.

10. Attach the other end of the long 3/8 in. OD air line

(G4) to the 3/8 in. push-to-connect fitting on the

shaker head (G1).

11. Ensure the adhesive pellets container is in the

desired operating location. The location should be

chosen to make it easy to fill the container with pel-

lets.
