5.1 Causes and elimination of faults
In the instructions below you will find some examples of faults, their causes and their correction.
There are often different causes, which must be investigated step by step. Do not apply all sugges-
tions simultaneously, but one after another, carrying out tests in between.
- Worn parts:
Replace in good time. Repairs are more expensive and less reliable.
- Defects in the electrical equipment:
These may only be repaired by a qualified electrician.
- Motor protection relay has tripped:
Check whether machine is locked (see below) or the stitching thickness is incorrectly set. Reset
the motor protection relay by pressing the reset button (see 3.5).
- The machine suddenly locks during stitching or wire-straightening:
Check whether a piece of wire or a staple has jammed between or behind the movable parts of
the stitching head. Unscrew finger-guard, former, bender and driver.
- Clinchers are jamming, have no or insufficient upward stroke:
Give the red star handle -43- a sharp, vigorous upward press, and repeat several times.
- Staple shanks are insufficiently bent:
Turn the red star handle -43- slightly to the right.
- Ejecting the staples from the clincher box:
The red star handle -43- can be used to eject staples or wire bits jammed in the clincher box:
give the red star handle -43- a sharp, vigorous pull upwards to overcome the pressure of the
spring.
