Preparation for Towing/Winching
up to machine no. 676354
The braking system components on this machine are integral
with the hydraulic drive motors and are covered in
Section E
Hydraulics
.
Since the brakes are locked 'ON' whenever the engine is
stopped, the following procedures should be followed before
attempting to move a disabled machine.
It is only possible to tow or winch the JCB Skid Steer Loader
for short distances at slow speed in a straight line. This is
because the steering function is inoperative unless the
machine is being self-propelled.
If at all possible repair the disabled machine where it stands.
If the machine needs to be returned to the workshop for
repair, it must be winched onto a trailer or lifted onto a truck
for transportation.
!
!
CAUTION
DO NOT attempt to tow/winch the machine without first
releasing the hydrostatic braking otherwise damage will
occur to the hydraulic pumps.
3-2-1-2
1
Block the wheels to prevent accidental movement when
the brakes are released.
2
Remove the operator's seat.
3
Using an internal hexagonal wrench, loosen the four
relief valves
A
on the hydraulic pump, by a maximum of
four turns.
!
!
CAUTION
DO NOT loosen the relief valves by more than four turns
otherwise hydraulic fluid will be lost.
3-2-1-3
4
Disconnect hose
C
from the pressure reducing valve.
Plug the hose and cap the adapter to prevent loss of
pressurised fluid.
5
Connect a hydraulic hand pump to the T-connector
B
in
the hydraulic feed to the brake circuit.
6
Use the hand pump to pressurise the brake circuit to 12
bar (174 lbf/in
2
) to release the brakes. Disconnect the
hand pump.
7
Remove the wheel blocks only when the machine is
hitched up ready for towing/winching. Keep personnel
clear of the machine while the blocks are removed.
After Towing/Winching
1
Tighten the four relief valves
A
to a torque of 55 Nm (40
lbf ft, 5.6 kgf m).
2
Reconnect hose
C
to the pressure reducing valve.
3
Turn the starter switch OFF. This will vent the pressure
in the brake circuit and re-apply the brakes.
