FLEXIBLE (ADJUSTA-BLOCK) DESIGN
The following procedure is performed on attachments
with flexible (ADJUSTA-BLOCK) design for contact pad
and stabilizer. This procedure can be performed with the
arms in place and the attachment mounted on the truck.
A Cascade 4-Point Force Distribution Tester is required for
this procedure.
IMPORTANT:
Clamp circuit pressure should be adjusted,
if required, prior to adjusting the pad camber. Refer to
Installation Step 11 (page 9).
1
Extend the arms to the most common load width.
Lower the contact pads to just above the floor.
2
Position the tester between the contact pads. Adjust
the tester spindle locations to be perpendicular to the
contact pad surfaces and to the desired position based
on the type of product being handled.
3
Clamp on the tester and hold activated for 5 seconds.
4
The tester will display
clamp force
and
percentage of
clamp force
for each spindle location and
total clamp
force
(sum of force of the four spindles).
5
Clamp force distribution should be within the desired
percentages and tolerances.
If the tolerance difference is greater than allowable
tolerance difference, the contact pads require pivot
block adjustment. Continue to Step 6 for adjustment.

Clamp force distribution can be changed at the
ADJUSTA-BLOCK locations on the right hand contact
pad. Tune as follows:
• Loosen the locking nuts 3 turns. Use an 8 mm allen
wrench to hold the capscrews.
• Adjust the collar using a 32 mm socket. Turn
the collar
CW
to
increase
clamp force,
CCW
to
decrease
clamp force. One full turn of the collar is
approximately 2 mm linear travel or 10% of force.
Follow adjustment sequence, Step 7.

Adjustment Sequence –
• Adjust force at location
2
to the desired specification.
Validate clamp force with tester and adjust as
required.
• Adjust force at location
4
to the desired specification.
Validate clamp force with tester and adjust as
required.
• Adjust force at location
1
to the desired specification.
Validate clamp force with tester and adjust as
required.
• Adjust force at location
3
to the desired specification.
Validate clamp force with tester and adjust as
required.
IMPORTANT:
When adjustments are made in Rows
A
or
C
, Row
B
must be adjusted by 1/2.
Example 1:
If location
2
in row
C
is increased
by 2 mm, the location above
2
in row
B
must be
increased by 1 mm.
Example 2:
If location
3
in row A is decreased
by 2 mm, the location below
3
in row
B
must be
decreased by 1 mm.
