Maintenance
Contaminated hydraulic oil can make maintenance necessary at
Schaeffler KG. If clean hydraulic oil is always used, maintenance is
restricted to changing the battery.
Changing the battery
If the voltage of the battery falls below 7 Volt, the battery symbol
is shown,
Figure 14
. Lift the battery cover outwards and change
the battery.
Replace a used battery promptly by a fresh battery if the battery
symbol is shown. Replace a damaged battery cover and seal
promptly, since the ingress of hydraulic oil will destroy the device.
Always mount and dismount the digital manometer using
the hexagonal nut, never the housing,
Figure 12
, page 18!
Dismounting

maintenance:
■

Unscrew the digital manometer (right hand thread) using
a wrench (A/F27).
Mounting
