Heavy Duty Industrial (HD-I) Side-Feed Type Applicator
408-8322
1. Turn drag release lever upward, raise feed pawl,
and pull strip back using long–nose pliers so lead
terminal is between strip guides.
2. Push down on the floating shear, then remove
shear retaining screw from side of shear holder.
3. Slowly release pressure on floating shear.
Compression spring will push it out of shear holder.
4. After removing floating shear, lift compression
spring out of shear holder.
5. Inspect spring for damage and replace it if
necessary. Refer to parts list for correct number.
6. Re–install floating shear(s) using reversed
procedure. If installing new shear, be sure part
number agrees with the number on the parts list.
7. Raise feed pawl and move lead terminal over
the anvil. Turn drag release lever down to lower
stock drag.
8. Check shear holder adjustment as described in
Paragraph 5.7, Adjustment of Shear(s) and Shear
Holder(s).
7.3. Crimper Replacement
DANGER
To avoid personal injury, be sure power to
machine is turned off" and the power cord is
disconnected before taking the applicator out of
the machine. The machine ram should be in the
raised position.
1. Remove the applicator as described in
Section 3, INSTALLATION and REMOVAL.
2. Loosen the crimper bolt slightly and remove ram
assembly from applicator by pulling upward. It may
be necessary to move the feed finger forward to
release the ram assembly.
3. Remove crimper bolt which holds the front shear
depressor, front shear depressor spacer, tubular
spacer, insulation crimper, crimper spacer, and
wire crimper in place on the ram assembly. Note
position of parts for re–installation.
4. Re–install parts using reversed procedure. The
upper end of the wire crimper must be up against
the pins on the ram assembly, and the top hole on
the crimper must mate with the roll pin in the ram
assembly. Tighten the crimper bolt only finger tight.
NOTE
i
Insulation crimpers with legs of equal length, that
are identical front and back, may be positioned
with either side out. All other insulation crimpers
must be positioned with part number facing the
direction noted during removal. If new parts are
used, be sure part numbers agree with numbers
on parts list.
5. Put ram assembly back into applicator, and
install applicator in machine.
6. Lift feed pawl and pull terminal strip back until
lead terminal is between strip guides.
7. Form a piece of heavy paper over anvil, then
slowly hand–cycle machine while watching
alignment of crimpers with anvil. When ram
assembly has reached bottom of stroke, carefully
tighten crimper bolt. Crimpers MUST move freely
over anvil after paper is removed.
7.4. Feed Pawl Replacement
DANGER
To avoid personal injury, be sure power to the
terminating machine is turned off" and the power
cord is disconnected.
1. Remove the adjustment screw which holds the
feed pawl to the feed finger (feed pawl holder).
2. Replace feed pawl using reversed procedure. If
new pawl is installed, be SURE the part number
agrees with the number on the parts list.
3. Adjust feed pawl as described in Paragraph 5.5.
7.5. Adjustable Crimp Height Repair
Under the insulation crimp disk is a laminated washer
which may break or compress after extensive use.
This could cause the applicator to produce
terminations with a different crimp height than
specified. To correct this problem, use the following
procedure.
DANGER
To avoid personal injury, be sure power to the
machine is turned off" and the power cord is
disconnected BEFORE removing the applicator.
1. Remove the applicator as described in
Section 3, INSTALLATION and REMOVAL.
2. Subtract specified nominal crimp height from
average crimp height recorded as a part of
Paragraph 5.2, Wire Crimp Adjustment. This
difference will be the thickness of washer(s)
(PN 690125–1) to be added under the insulation
crimp disk.
NOTE
i
Washer 690125-1 is a set of four steel shim
washers that are 0.05mm, 0.076mm, 0.127mm,
and 0.254mm thick.
3. Remove ram assembly from applicator, and
loosen ram post locking screw in the side of
applicator ram (see Figure 1).
4. Hold ram assembly with ram post pointing
down, and unscrew ram from ram post, leaving
