Using the feed-forward adjustment knob, change the feed-forward position based on the direction
and amount noted in step 4.d. The adjustments are in 0.04 mm [.0016-in.] increments or
15 degrees and can be felt as clicks during the feed-stroke adjustment knob rotation. Turning the
feed forward adjustment knob
clockwise
moves the feed pawl away from the anvil and turning it
counter-clockwise
moves the feed pawl toward the anvil.
NOTE
When adjusting, make sure that only the feed adjustment knob turns, not the entire shaft. The backstroke adjustment knob may
have to be held stationary to prevent unintended backstroke adjustments (use a 3-mm wrench when the end cap is in place).
Cycle the machine back to top-dead-center, causing the feed to shift forward and feeding the
terminal over the anvil. Repeat steps 4.d. through 4.h. until the terminal is centered over the anvil.
5. To adjust the air feed speed, proceed as follows:
NOTE
The air feed speed has been set at the factory and should therefore require re-adjustment
only in exceptional circumstances.
NOTE
Take extra precautions during adjustments. When the machine is manually cycled, the mechanism will move forward and
backwards once during each press stroke unless the air is disconnected.
CAUTION
Do not tamper with the detent screws on feed adjustments (see Figure 2), which were set up properly by the factory;
otherwise, damage will occur.
The feed mechanism was adjusted at the factory to ensure the terminal is advanced at the lowest
possible speed. On rare occasions, the feed speed may not be fast enough if the applicator is used
on a fully
automatic machine. The feed speed can be increased by adjusting the two exhaust
restrictors.
(1) Open the exhaust restrictors or Forward Speed Control and Retract Speed Control (shown in
Figure 2) to increase the feed speed.
NOTE
The speed controls should not be fully opened to maximize feed speed. Excess
i
ve feed and/or retract speeds can cause
inconsistent feeds and/or air feed module damage. It is recommended to only open the flow control valves two complete
revolutions.
(2) Loosen the locking ring, and turn the adjustment screw
clockwise
to decrease the speed and
counter-clockwise
to increase the speed. When complete, tighten the locking ring.
