Maintenance Schedule
The maintenance intervals are very dependent on the individual operating conditions. The following
information provides initial values that can be shortened or extended as necessary. In particular,
operation under difficult conditions, such as
conditions with high levels of dust or loose particles from workpieces, or
high levels of needle wear, due to hard or abrasive workpieces, for example,
can make it necessary to considerably shorten the maintenance interval.
Clean all signs of contamination during any form of maintenance.
Recommended cleaning interval every 1 million cycles.
Opening and sealing the maintenance openings
WARNING
Extending needles
Injuries caused by pricks, cuts and scratches
►
Wear cut resistant gloves

Inserting the needle holder
Insertion of the needle holder occurs in the same way as removal but in the reverse order.
IMPORTANT
The position "needle retracted" was adjusted
Malfunctions and damage to the gripper is possible
►
The position "needle retracted" of the gripper must be reached before needle
holders can be inserted - see chapter Fehler! Verweisquelle konnte nicht
gefunden werden..
►
No further changes to the position of the worm wheels may be made after the
needle holders have been inserted
Installation of the cover
Installation of the covers occurs in the same way as removal but in the reverse order.
The pressure bolts make an audible click if the covers have been mounted
correctly.
IMPORTANT
Operation of the gripper without covers
Malfunctions and damage to the gripper
►
Covers of the needle holder must be ensured
Inspecting the gripper after the needle holders have been changed
If the aforementioned installation steps were carried out successfully,
1.) the needles do not protrude from the grip surface of the housing
2.) the two needle holders have the same stroke
3.) the needle stroke corresponds to the set stroke in the scale
Should one of the requirements not be met, the following steps are to be performed:
1. Remove the two needle holders. See 0
2. Start up the position "needle retracted" again
1. Insert the two needle holders. See 0
We recommend a test run prior to start of operations for the gripper.
Hold the opposite needle holder securely when inserting the needle holder. This
allows the position "needle retracted" to be secured.
