• Do not overload the tool. Work only within the indicated capability range.
• Do not operate the tool without installing a rivet nut.
• Regularly check compressed air connections with respect to tightness and leakage.
• Always disconnect the tool from compressed air supply when tool is not in use or when
servicing.
• When working with the tool, always wear protective safety glasses. Personal safety
equipment such as protective clothing, protective gloves, helmet, nonslip shoes and hea-
ring protection are recommended in order to safeguard against accidents.

6. Starting procedure
Before starting, carefully read and follow operating instructions!
6.1 Adjustment of mandrel length "X"
• Disconnect tool from compressed air to unlock the threaded mandrel.
• In case of standard blind rivets nuts «a» the protruding part of the threaded mandrel (2)
must be as long as the whole blind rivet nut (see drawing 1) and is hand adjusted by
turning the mandrel either in or out.
• In case of closed-end rivet nuts «b» use entire threaded depth.
• To lock the length adjustment connect tool to compressed air and the locking device is
engaged automatically.

6.2 Adjustment of stroke "Y"
The stroke «Y» (see chart) depends on the blind rivet nut size (M3 to M10, 6-32 to 3/8-16)
and the material thickness «Z» (drawing 2).
Stroke chart for GBM 95:
Thread size Stroke min. "Y" mm max.
M3 0.5 - 1
M4 1 - 2
M5 1.5 - 2.5
M6 2.5 - 3.5
M8 3.5 - 4.5
M10 3.5 - 4.5
• Loosen lock nut (3) (drawing 1).
• Adjust stroke «Y» by turning in or out the nosepiece (1).
• Stroke «Y» has to be adjusted to «min», to be locked (tightened) and then the rivet nut
has to be set.
• If the blind rivet nut does not form a proper sealing head (as shown in drawing 2) the stro-
ke «Y» must be increased step by step. Afters stroke adjustment, the lock nut (3) has to
be tightened.

6.3 Threading-on and setting of a blind rivet nut
• Place the rivet nut in front of the threaded mandrel (2) (see drawing 3) without tilting and
push the thread-on button (35).
• Holdtheblindrivetnutduringtheentirethreadingprocessuntilittstightlyagainstthe
nosepiece (1).
• Insert the blind rivet nut into the workpiece, ensuring that the fastener´s head is fully sea-
ted. Next set the blind rivet nut by pressing the stroke button (35).
• Hold button (35) until blind rivet nut is set completely.
• Release button (35). The threaded mandrel (2) is threaded off automatically.

Attention!
In order to avoid upsetting smaller or thin-wall type blind rivet nuts during the threa-
ding process, disconnect tool and increase the threaded mandrel protusion to a length
suchthattherivetnutdoesnotthreadonushagainstthenosepiece.Adjustsetting
stroke (see paragraph 6.2)
Important:
• If the threaded mandrel (2) is not threaded out of the blind rivet nut completely, a short
quick touch of the stroke button (35) will induce threading-out procedure.
• If the threaded mandrel is stuck in the blind rivet nut, it may be loosened by means of the
enclosed hexagon wrench SW4 (see drawing 4).

7. Maintenance and service
Special maintenance is not necessary. If applicable, exchange worn threaded mandrels ac-
cording to paragraph 6.4. When not in use the tool should be kept in a dry room.
6.4 Change of threaded mandrel
• Disconnect tool from compressed air supply.
• Loosen lock nut (3) (drawing 1).
• Unscrew nosepiece (1).
• Unscrew threaded mandrel (2) by turning backward and forward until mandrel releases.
• Screw in new threaded mandrel.
• Screw in corresponding nosepiece (1) with lock nut (3).
• Adjust setting stroke «Y» and length of threaded mandrel «X» (see paragraphs 6.1 and
6.2).
6.5 Change of unthreading time
• The adjusting screw at the edge of the handle near the air connection can be reached
with enclosed ball-headed screw driver SW 2.5 mm (see drawing 5).
• A slight turn to the right increases the unthreading time.
• A slight turn to the left reduces the unthreading time.
