8 Service and maintenance
Warning
Uncontrolled moving masses can cause injury to people or damage to property
(squeezing). Signals from the controller may cause inadvertent movements of
the EHMB.
· Switch off the controller for all work on the EHMB and protect it from being
switched on again unintentionally.
Note
Due to its life−time lubrication, the slot shaft guide
4
at first moves somewhat
sluggishly.
After a start−up phase, the guide’s friction decreases and the excess grease can
be wiped off.
· Clean the EHMB if required with a soft cloth.
Cleaning agents: any gentle detergent.
To extend the service life of the linear guide:
· Dismantle the cam fixture (H) as follows:
Unscrew threaded pin (SW2)
Shift cam fixture upwards
· Grease the ball bearing of the guide
at the 3 lubrication holes every 3000 km
(grease
è
chapter10 Accessories").
The amount of grease is:
2.3 g (for EHMB−20)
4.7 g (for EHMB−25/32).
· Shift the linear part backwards and
forwards during lubrication. Otherwise
the grease cavities will not be filled to an
equal extent.
· Reassemble the cam fixture (H). The tightening torque of the threaded pin is
1Nm.
· Check whether the proximity sensors operate as desired.
· Correct the position of the cams, if necessary ( è chapter 5 Electrical
installation")
