Front Flow Control
(labeled 2 on drawing 27563-2) – commonly known as “meter-out” type, it controls
the air exhausting from the cylinder, it is used to adjust the speed of the ATC cylinder as it extends toward
the work table.
Initial adjustment : close the flow control all the way**, mark the knob with a black marker to
establish a reference starting point, and then open it 10 full turns.
Front Internal Cushion adjustment - this air cushion controls the deceleration of the cylinder when it is
within the last 40mm of its full extension. It causes the cylinder to slow down gradually near the end of the
extend stroke. See figure 5.9a.
Initial adjustment : using a 3mm allen wrench, close the cushion all the way down, and open it
¾ of a turn.
Final Adjustment:
Compete all initial adjustments. Load the ATC with a full set of tools.
Operate the ATC forward and backwards. Slowly wind out the adjustment screw until the
deceleration of the ATC is smooth and soft.
Rear Flow Control (mounted on the exhaust port of the quick exhaust valve, labeled 1 on drawing 27563-
2) - this “metering-out” type flow control is used to control the speed of the ATC cylinder as it retracts back
to its home position.
Initial adjustment : close the flow control all the way, mark the knob with a black marker to
establish a reference starting point, and then open it 3 ½ turns.
Rear Internal Cushion adjustment
– this air cushion controls the deceleration of the cylinder when it is
within the last 40mm of the full retraction. It causes the cylinder to slow down gradually near the end of the
retract stroke.
Initial adjustment : close the cushion all the way down, and open it 1 full turn. Figure 5.9.2
shows both cushions on the ATC cylinder.
Final Adjustment: Compete all initial adjustments. Load the ATC with a full set of tools.
Operate the ATC forward and backwards. Slowly wind out the adjustment screw until the
deceleration of the ATC is smooth and soft.
