with Service Key
The manual actuation in the Service mode is useful for testing the
electrical and hydraulic functions of the of the lubrication system.
The pause time is reduced to 30 seconds and the holding time to
15 seconds permitting rapid sequences of lubrication cycles. Both
lubrication systems can be set to the manual actuation mode.

system are made inoperative and, because of the very short
pause and holding times, grease will not reach to all lubrica-
tion points.

1. Insert key into service switch (3) and set to operating position.
2. Actuate the rotary switch (1) on the instrument panel. The
message # SERVICE appears on the display. Up to ten
repeated actuation of the switch are possible. The lubrication
cycles are counted and displayed in the cycle counter win-
dow.

system returns to the normal timer settings.
