3.2 Shearing Adjustment using the Tension Nut
Before putting into operation, make adjustments as follows:
Before Shearing:
With the machine disconnected from the shearing drive: ensure that the Yoke’s carrier (chicken
feet) cone pins mesh precisely into the positioning holes in the cutter (Illustration 2, Item 2).
Tighten the tension nut until resistance is first noticeable (Illustration 2, Item 1). Then tighten
the tension nut a further 1⁄4 turn.
Connect the handpiece to the shearing drive (observe advisory notes listed at 2.4.1) and start
operating the shearing drive motor. Slacken off the tension nut (Illustration 3) until the shearing
blades exert almost no more contact pressure (noise level rises).
Caution! If the tension is slackened off too much, the cutter can fly off causing injury.
Now tighten the tension nut slowly until the noise level becomes muffled and some resistance
is detectable as you tighten the tension nut. The pressure should now be correctly set. Begin
shearing. If it still does not cut properly, you will have to add a little more tension.
During Shearing
Provided the shearing blades are properly sharpened (ground) the shearing system works with
much less pressure having to be applied than with traditional shearing machines. Care should
be taken, therefore, to ensure that the blade tension is not set too high. Too high tension
causes more friction and reduces the life expectancy of the shearing handpiece as well as the
shearing blades. Slightly adjust the blade tension from time to time during shearing (max. 1⁄4
turn).
Hair may collect between the shearing blades, if the tension nut is insufficiently tightened at
the start of shearing. This will have an adverse effect on further shearing progress or make it
quite impossible. If this happens, the shearing blades must be disassembled, cleaned, oiled
and re-fitted as described at 4.2 (Fitting the Shearing Blades)
