Vane:
If the minimum diameters (see drawing) are not reached anymore, the vanes P35.2024 or P35.3108 must be
exchanged.
Assembling of the cover P35.3105
on the idler step P35.0130
Observe assembling direction of the cover.
The division of the holes is not 3x120°.
The cover must be easy to assemble.
If the cover is assembled distorted, the gear
runs bad.
Elastomer Spring and Thrust Piece:
When assembling the end cover P38.1147, pay
attention to the assembling direction of the spring
P35.2026 and the thrust piece P35.2027. (see
drawing)
Thrust piece towards the motor.
Attach parts with grease on the motor cover!
The same assembling position is valid at the
welding motor too!

Exchange of strap guides and strap stop
Disassembling:
• For protection of the tooth system from the gripper a piece of plastic strap should be inserted
before loosing or tightening the base plate. (therefore lift the handle)
• Unscrew base plate
• Disassemble the end cover P38.0119
• To extract the strap guides P38.1160/62/64/66 and P38.1161/63/65/67 respectively pull down the
thrust pieces P38.1110 and P38.1111 and swivel them to the side. (Picture 2)
The thrust pieces P38.1110 and P38.1111 are arranged in mirror image.
• Extract the strap guides P38.1160/62/64/66 and P38.1161/63/65/67
• Unscrew the strap guide P38.1158/59
• Disassemble the strap stop P38.1154/56/57
Assembling:
• Set the thrust pieces to swivel in position. (Picture 2)
• When setting in the strap guides P38.1154/56/57 push them in to the level of the welding gripper.
• Swivel back the thrust pieces
• Release the strap guide and check the function. (Press in and release the strap guide 2 or 3
times)
• Assembling of strap stop P38.1154/56/57 and strap guide P38.1158/59 in opposite order.
• When assembling the strap guide P38.1158/59 pay attention to the width of the strap.
The number of the used strap width has to show to the inside.

Adjustment of the strap guide after service or repair work
If the strap guides P38.1160/62/64/66 and P38.1161/63/65/67 don't touch the base plate or after the welding
you see pressure points at the side of the upper strap you have to adjust the strap guides:
- Disconnect the tool from the air supply.
- Remove the end cover P38.0119. (Picture 1)
- The free play of the thrust pieces P38.1110 and P38.1111 should be 0 - 1.5mm otherwise they have to be
readjusted.
Readjusting with disassembled piston
P38.0101 (Picture 3):
- Loose the screw N11.1116.
- Preset the pusher P38.1105 to the
measure 21.5mm
- Increasing of the preset measure
21.5mm increases the free play.
Decreasing of the preset measure
21.5mm decreases the free play.
In order to check the free play the
piston must be assembled again!
The free play must be sensed by
moving up and down the thrust piece.
