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 nipples (see illustration) with approx. 0.5 cm³ grease approximately every 8 operating hours. A non-acidic, viscous grease with MoS2 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 system EDS**	wear of the sealings in the cylinder lack of lubrication
Wear control of the clamping set	weekly	visually	loss of torque loss of accuracy
Mounting check of the clamping set parts	weekly	check screw connection	loss of torque loss of accuracy
