7/124 - 10/104, 10/124 - 14/114, 14/84
Check the position of the hand brake lever [1]. The start of resistance
should be approximately 10-15mm above the horizontal position.
Check that the wheels move freely when the handbrake is disengaged.
Final test
Check the fasteners on the transmission system (cables, brake
equalisation system and linkage).
Check the handbrake cable [5] for a small amount of play and adjust if
necessary (Variable height only)
Check the compression spring [9] for pre-tensioning.
Test run
If necessary carry out 2-3 test brake actions.
Test brake action
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
handbrake lever up to
2
/
3
of maximum is allowed.
RE-ADJUSTING THE OVERRUN BRAKING SYSTEM
(KNOTT RUNNING GEAR)
Re-adjustment of the wheel brakes will compensate for brake lining
wear. Follow the procedure described in
2: Brake Shoe Adjustment.
Check the play in the brake linkage [7] and re-adjust if necessary.
Important
Check the brake actuators and cables [11]. The brake actuators must
not be pre-tensioned.
Excessive operation of the handbrake lever, which may have been
caused by worn brake linings, must not be corrected by re-adjusting
(shortening) the brake linkage [7]
Re-adjustment
The handbrake lever [1] should be engaged forcefully several times to
set the braking system.
Check the setting of the brake equalisation assembly [8], which should
be at right angles to the pulling direction.
Check the play in the brake linkage [7] again, ensuring that there is no
play in the brake linkage and that it is adjusted without pre-tension
Check the position of the hand brake lever [1], cable [5] (with little play)
and the compression spring [9] (only slight pre-tension). The start of
resistance of the handbrake lever should be approximately 10-15mm
above the horizontal position.
Final test
Check the fasteners on the transmission system (cables, brake
equalisation system and linkage)
Apply the handbrake while rolling the machine forward, travel of the
handbrake lever up to
2
/
3
of maximum is allowed.
Check the handbrake cable [5] for a small amount of play and adjust if
necessary (Variable height only)
Check the compression spring [9] for slight pre-tensioning.
