FEEDWHEEL ADJUSTMENT
SCREW LOCATION (ARROW)
FEEDWHEEL TO GRIPPER PLUG
The feedwheel to gripper plug clearance may require readjustment if the feedwheel or gripper plug
has been replaced. The feedwheel clearance should also be inspected during routine tool
maintenance procedures. Adjust the feedwheel clearance as follows:
1.
Squeeze the tension motor and stationary handle
together to open the feedwheel gap. Place multiple
(4 to 8) layers of .002", 1/2" wide (.05 x 12mm) shim
stock between the feedwheel and the gripper plug.
NOTE: Do not use a single shim such as .008"
(.20mm) as thicker shims may not conform to the
feedwheel shape, resulting in inaccurate clearance
measurements.
2.
Release the tensioner motor to pinch the shims
between the feedwheel and the gripper plug.
Holding the shims with one hand, jog the tension
motor on and off to rotate the feedwheel at least one
full revolution. If properly adjusted the tool should
lightly tug at the shims while rotating. Clearance between the feedwheel and gripper plug at
this point should fall between .008" to .016 (.20mm to .40mm).
3.
If the feedwheel needs to be adjusted, use a 3mm hex
wrench to turn the adjustment screw which can be
accessed through the bottom of the tool base.
Turn the adjustment screw clockwise for greater
clearance and counter-clockwise for less clearance.
Turn the adjustment screw only in 1/8 turn increments.
After each 1/8 turn, repeat the adjustment testing as
described in step 2.
4.
Once the proper clearance has been found the tool
can be returned to service.
NOTE: Never turn out the adjustment screw more than
1/8 turn at a time without testing or completely remove
the adjustment screw. These actions will severely
damage both the feedwheel and gripper plug.
STRAP TENSION
Strap tension is controlled by turning the adjustment screw
(Key 98) as shown by arrow, in 1/4 increment turns
counter-clockwise to increase strap tension and clockwise
to reduce strap tension. Use the 4mm hex
wrench
included with every new tool.
NOTE: Operating air pressure must be set between 85 and
90 psi (5.7-6.2 Bar). With accurately controlled air pressure
the tension will be uniform on all straps, provided the
operator allows the air motor to stall.
