5.7.6 Exciter: oil level/oil change
Check / change exciter oil when its warm.
The venting screw must always first be unscrewed
when checking the oil level or changing the oil.
Important
Motor oil
SAE 10W40
API SG-CE
–
Unscrew venting screw, oil filling plug (2) and oil drain plug (1).
–
Drain old oil.
Care is to be taken with the draining of hot oil :
danger of scalding!
Danger
Collect oil which has run out or overflowed and
dispose it in an environment friendly manner.
Environment
–
Replace oil drain plug (2).
–
Fill new oil via oil filler hole (1); oil quantity and quality, see lu-
brication chart.
–
Replace oil filling plug (2) and venting screw.
In order to guarantee sufficient lubrication, the oil
level must be between the «min» and «max» mark
on the dipstick. With a lesser level of oil there
Attention
exists a danger of gear damage through overhea-
ting.

–
Release locking screw (1).
–
Set throttle lever (2) to «V».
–
Pour in hydraulic fluid whilst continually changing the throttle
lever position. To ensure correct bleeding, from time place the
shaft vertically.
–
Stop filling when
•
a distinct «clicking»-noise is heard in the exciter whilst shif-
ting the lever
•
you no longer feel a cushion of air when moving the throttle
lever
When filling, the circuit path is shortened.
Important
–
To check oil level, start engine and bring up to operating
speed.
–
Move throttle lever several times backwards and forwards bet-
ween «V» and «R».
–
The correct oil level should be somewhere in the area shown
(See Illus.); at this point the throttle lever must be in the «V»
position.
–
If the level is too low, top up with hydraulic fluid; if too high,
drain off excess fluid.
–
With the machine running and the throttle lever in the «V» po-
sition, close locking screw (1).
