6. Spare parts
When ordering spare parts, please quote the Ident. No. of the chuck and the item number or designation of the desired part
(see page 2). -- The Ident. No. will be found on the face of the chuck.
5. Maintenance
The level of maintenance of the clamping device determines
its functionality, clamping force, accuracy and service life.
Regular maintenance consists of charging the grease nip-
ples (see illustration) with approx. 0.5 cm
3 grease approxi-
mately every 8 operating hours. A non--acidic, viscous
grease with MoS
2
additive should be used for this purpose.
We recommend our F90* grease in this respect.
Several no--load clamping strokes should be completed
after lubricating to distribute the grease applied evenly.
The guides for the 3 wedge bars and 3 clamping jaws are
supplied with lubricant via the grease nipples.
Blowing out:
Never blow into the jaw guides or guide slots with air.
Preventing maintenance work:
Check-list Period Procedure Possibility of error
Checking clamp. force every 6 months Clamping force measuring wear of the sealings in the cylinder
system EDS** lack of lubrication
Wear control of the weekly visually loss of torque
clamping set loss of accuracy
Mounting check of the weekly check screw connection loss of torque
clamping set parts loss of accuracy
