Procedure 6

. Checking the Brake

Liquid Level in the Compensation

Chamber of the Master Cylinder for

Controlling the Clutch and Brakes in the

Reverse

The fluid level shall be within the “AND

”

distance from the upper edge of the

compensation chamber. If necessary,

remove the boot and add fluid to the re-

quired level.

Procedure 7. Draining Condensate

From the Hydraulic System Bottle

To drain condensate from the bottle, pull

the ring (1) to any side if the bottle con-

tains compressed air. Hold the ring in

this position till condensate is completely

drained.

Procedure 8. Checking the Operability

of the Engine, Steering Control,

Brakes, Lighting and Signalling De-

vices

The engine shall demonstrate the stable

run in all duties.
The controls, light and sound signalling

systems should be in good order.
The simultaneous operation of the right-

and left-hand service brakes shall be en-

sured.
