Shearing Adjustment Using The Tension Nut - Heiniger XTRA Manual De Instrucciones

• Only use original shearing blades. Do not use damaged shearing blades with blunt,
missing or broken off teeth. Only work using sharp shearing blades, ground in a specialist
workshop.
• We recommend you use a comb for no longer than an hour and a cutter for no longer
than 15 minutes before you change them for a sharp comb and cutter.
• Look out for foreign bodies (wire, wood, etc.) in the fleece and remove them before
beginning to shear.
• Wear suitable work clothes. Do not wear any loose fitting clothing or items of jewellery
which could get caught up in moving machine parts. We would recommend in the
strongest terms that protective goggles and ear protectors are worn.
• Never insert any object into any of the machine's apertures.
• Noise from the machine can worry animals. Considerable injury can be caused as a
result of being kicked by an animal or being crushed by its body weight. Tether the animal
securely, approach it from in front and switch the machine on within the animals' range of
vision.
• Animals should only be shorn if unauthorised persons have been excluded from the
shearing area.
• Only shear in well-ventilated spaces (dust) and never near objects or gases likely to
explode.
• Generally, never plunge the clipper and clipperhead into liquids such as water, soapy
water, diesel, petrol, etc. This may cause serious injury to mechanics and motor.
These safety notes must be complied with in all cases. It is recommended that a fault current
safety plug always be used when working with electrical equipment.

3.2 Shearing Adjustment using the Tension Nut

Before putting into operation, make adjustments as follows:
Before shearing:
With the machine switched off: ensure that the pressure yoke's carrier cone pins mesh
precisely into the positioning holes in the cutter (Illustration 3, Item 2). Tighten the tension nut
until resistance is first noticeable (Illustration 3, Item 1). Then tighten the tension nut a further
1/4 turn.
Illustr. 3/7
Start operating the shearing machine. Slacken off the tension nut (Illustration 7) until the
shearing blades exert almost no more contact pressure (noise level rises).
Caution! If the tension nut 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:
The shearing system works with much less pressure having to be applied than with tradi-
tional sheep shearing machines. Care should be taken, therefore, to ensure that the blade
tension is not set too high. Slightly adjust the blade tension from time to time during shearing
(max. 1/4 turn).
