Working hydraulics

WARNI NG
The service brake hydraulic servo-assistance is only fully efficient with the second operation
of the brake pedal, when the red pilot lamp 24 is off.
Before each trip, the brake pedal must be pressed until it gives way noticeably.
CAUTION
Do not use the hand-brake at temperatures below 0 °C (danger of freezing brake linings).
When the Transporter has been exposed to freezing temperatures, always start up by using
the high ranges 'H' to prevent damage to the drive train, in the event that the brakes are fro-
zen up. If the engine stalls, the brakes are frozen up and must therefore be thawed.
Engaging the PTO shaft:
1. Disengage the PTO shaft by means of the clutch lever 14 (pull the lever).
2. Engage the PTO shaft by means of the change lever 15.
3. Slowly engage the PTO shaft using the clutch lever 14.
When the PTO shaft is not in use, the PTO shaft changeover lever 15 must be set to 0 and
the PTO shaft clutch must be engaged using lever 14.
NOTE
If the clutch lever 14 is constantly pulled, this causes rapid wear to the withdrawal lever and
withdrawal bearing.
Taking the self-loader as an example, the operation of the hydraulics is as follows:

Lever 36: Raising and lowering of pick-up. If the lever is pushed beyond the lower position,
it locks in the float function position.
Lever 37: Opening the back wall. If the lever is pushed beyond the lower position, it locks in
the float function position (rear wall remains open and must be closed using the non-return
valve at the rear of the self loader).
Lever 38: Scraper floor forwards and backwards. Lever locks on both sides.
Flow control valve 39: Limits the flow in the hydraulic valve 38. This allows the regulation of
the scraper floor speed.
CAUTION
The hydraulic valve 38 should only be engaged in the "Pressure" position when the consumer
(hydraulic engine) is connected since otherwise the entire oil quantity flows through the pres-
sure control valve. As a result of this the hydraulic and gear oil rises considerably.
NOTE
If the temperature of the hydraulic and gear oil rises to above 100°C an acoustic warning sig-
nal sounds.
CAUTION
Keep hydraulic plugs and couplings clean at all times.
After connecting an implement or attachment, the directions of movement must be checked
and an inspection carried out to ensure that they match the corresponding switches.
NOTE
With single action hydraulic cylinders, the piston rod is pushed out by oil pressure, and
pushed back on release of the pressure by the weight of the lifting gear (and the attachment).
