screws that secure the base plate to the cross member.
6
Remove the base plate.
7
To enable the leg pivot pin to be inspected, it will be necessary to remove the set pin that holds the piston end of the actuator
in place on the cross member. Once the pin is removed the leg and the actuator can be lifted free from the cross member.
8
Remove the leg and actuator taking care not to lose the bronze bearing washers at each end of the leg pivot pin.
NOTE:
Support the actuator to prevent damage to the mounting point still attached to the leg. If any work is to be done on the
leg, it is safer to remove the actuator.

that secures the actuator piston to the centre of the cross member and
tighten to 5 Nm
.
7
Replace the plates.
8
Apply loctite to the M6 CSK screws and
tighten them to 5 Nm

Ensure the leg actuators open and close the legs correctly.
NOTE:
Before applying threadlock to any screw or bolt check it can be screwed into the component without hindrance from old
remaining threadlock. This could affect the proper torque setting.
