Portable Compressor 7/20
9---7
SEPTEMBER 2003
When the brake has been adjusted accurately the actuating
distance is approximately 5÷8 mm (0.18÷0.3 in) on the bowden
cable
11
.
(3.) Compensator Assembly Adjustment
Variable Height models
Fit an M10 safety screw to the handbrake pivot.
Disconnect the brake cable
5
at one end.
Pre---adjust brake linkage
7
lenghtways (a little play is
permissible) and re---insert the brake cable
5
, adjusting it to give
a small amount of play.
Remove the M10 safety screw from the handbrake pivot.
All models
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
bowden cables
11
.
The compression spring
9
must only be slightly pre---tensioned
and when engaged must not touch the axle tube.
(4.) Brake Linkage Adjustment
Adjust the brake linkage
7
lengthways without pre---tension.
Readjustment
Engage the handbrake lever
1
forcefully a number of times to set
the brake.
Check the alignment of the equalisation assembly
8
, this should
be at right angles to the pulling direction.
Check the play in the brake linkage
7
.
If necessary adjust the brake linkage
7
again without play and
without pre---tensioning.
There must still be a little play in brake cable
5
(Variable Height
Only).
Check the position of the handbrake lever
1
. The start of
resistance should be approximately 10÷15 mm (0.39÷0.59 in)
above the horizontal position.
Check that the wheels move freely when the handbrake is
disengaged.
Final test
Check the fastenings on the transmission system (cables, brake
equalisation system and linkage).
Check the brake 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.
9.20.1.
Re-- adjusting the 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.
A. Important
Check the brake actuators and bowden cables
11
. The brake
actuators must not be pre---tensioned.
Ixcessive 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
.
B. 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 handbrake lever
1
, brake
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÷15 mm (0.39÷0.59 in) above the
horizontal position.
C. Final Test
Check the fastenings 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 brake cable
5
for a small amount of play and adjust
if necessary (Variable height only).
Check the compression spring
9
for slight pre---tensioning.
CAUTION
CHECK THE WHEEL NUT TORQUE 30 km (20 miles) AFTER
REFITTING THE WHEELS (REFER TO THE
Table 9---2.
TORQUE VALUES
IN THIS SECTION).

CAUTION
ALWAYS CHECK THE OIL LEVELS BEFORE A NEW
MACHINE IS PUT INTO SERVICE.
If for any reason the unit has been drained it must be re---filled
with newoil before it is put into operation.
