Mount/Demount Tool Head Adjustment
To Adjust Tool Head Lift
Shoulder screw (ref. 1) sets the tool head lift for
metal duckheads—no adjustment required. Place
shim 85606345 on screw if using a plastic
duckhead.
To Adjust Lock Tightness
With lock handle unlocked, loosen jam nut (ref. 3)
and adjust pin (ref. 4) until a slight firmness is
obtained, then tighten jam nut and check. Also
recheck tool head lift at this time.
Separator/Lubricator Maintenance
Check oil and water levels regularly, and perform
these maintenance items weekly:
A. Disconnect air supply to machine.
B. Drain water from the separator by unscrewing
the petcock on the bottom of bowl. Allow water
to drain and tighten petcock securely by hand.
C. Add oil to the lubricator if the fluid level is more
than 1/4” from the top of the gauge. Remove the
filler plug on top of the lubricator and add SAE
10W non-detergent oil or an air tool oil to bring
the level up to 1/4” from the top of the gauge.
Replace filler plug and clean up any spilled oil.
D. Adjust the oil flow by pulling the red flow
adjustment ring up and turning it to increase or
decrease the flow. Push the ring down to lock.
Watch the formation of oil drops in the see-
through oil chamber. Reconnect the air supply
and continually cycle the bead loosener through
full strokes and count the drips during the
cycles. The delivery of oil to the air line should
be about 1 drop per 10 cylinder cycles. Adjust
flow as required.
Mount/Demount Head Cleaning
Clean dirt and debris from the mount/demount tool
(duckhead) roller with small screw driver or pick.
