Operation and Maintenance Manual
Brake Shoe Adjustment
Figure 10
1. Tighten adjusting screw [12] clockwise until the
wheel locks.
2. Loosen adjusting screw [12] anti-clockwise
(approx. 1/2 turn) until the wheel can be moved
freely.
3. Repeat the adjustment on the other wheel brake.
Note: Slight dragging noises that do not impede
the free movement of the wheel are
permissible.
Note: When the brake has been adjusted
accurately the actuating distance is
approximately 5-8mm on the cable [11]
Compensator Assembly Adjustment
Variable Height models
1. Fit an M10 safety screw to the handbrake pivot.
2. Disconnect the handbrake cable [5] at one end.
3. Pre-adjust brake linkage [7] lengthways (a little play
is permissible) and re-insert the cable [5], adjusting
it to give a small amount of play.
4. Remove the M10 safety screw from the handbrake
pivot.
All Models
1. Engage the handbrake lever [1] and check that the
position of the equaliser plate [10] is at right angles
to the pulling direction. If necessary correct the
position of the equaliser plate [10] on the cables
[11].
2. The compression spring [9] must only be slightly
pre-tensioned and when engaged must not touch
the axle tube.
Brake Linkage Adjustment
1. Adjust the brake linkage [7] lengthways without pre-
tension and without play in the transmission lever
[4].
Readjustment
1. Engage the hand brake lever [1] forcefully a
number of times to set the brake.
2. Check the alignment of the equalisation assembly
[8], this should be at right angles to the pulling
direction
3. Check the play in the brake linkage [7]
4. If necessary adjust the brake linkage [7] again
without play and without pre-tensioning
5. There must still be a little play in cable [5] (Variable
Height Only)
6. Check the position of the hand brake lever [1 ]. The
start of resistance should be approximately 1 0-
15mm above the horizontal position.
7. Check that the wheels move freely when the
handbrake is disengaged.
Final Test
1. Check the fastenings on the transmission system
(cables, brake equalization system and linkage).
2. Check the hand brake cable [5] for a small amount
of play and adjust if necessary (Variable height
only)
3. Check the compression spring [9] for pre-
tensioning.
Test Run
1. If necessary carry out 2-3 test brake actions.
Test Brake Action
1. Check the play in brake linkage [7] and if necessary
adjust the length of brake linkage [7] until there is
no play.
Apply the handbrake while rolling the machine forward,
travel of the hand brake lever up to 2/3 of maximum is
allowed.
