Essential Operator Skills
•The operator must be the trained in the safe use of the machine.
•The operator must be experienced in handling the animals to be shorn.
Operation
•Only connect to a 12 volt DC power supply.
•Always disconnect the power supply before changing combs and cutters.
•Keep away from all liquids.
•Never shear wet animals.
•Never wrap the power cable around the machine.
•Switch the machine to the off position before pulling out the plug.
•Do not use combs with missing or broken teeth.
•Sharpen combs and cutters on a specialist grinder.
•Look out for wire, etc, in the fleece. Remove before shearing.
•Keep clear of ear tags.
•Keep unauthorised persons clear of the shearing area.
•Store the machine in a clean and dry place, out of the reach of children.
•Check the machine body and electrical cable for defects before use.
Circuit Breaker
•The 12v to 24v step up is equipped with a circuit breaker which will trip in the event
of an overload. To reset the breaker, press the button on the side of the step up.
Tension Adjustment before Shearing
•While the machine is still switched off, ensure that the conical pins on the chicken
feet sit exactly into the positioning holes in the cutter.
•Tighten the tension nut until resistance is felt (illustration 1). Do not over-tighten.
•If it is not cutting properly at the start of shearing you can add a little more tension.
•Do not slacken off tension while the machine is running.
•During shearing hair may collect between the comb and cutter if tension is not
sufficient. If this happens, the comb and cutter should be removed, cleaned, oiled
and re-fitted (as shown in illustration 2).
Switching on and off
•There are two positions on the rocker switch. In position 1, the machine is on. In
position 0, the machine is switched off.
•Put the rocker switch in the off position before plugging in the cable.
Lubrication
•Before and during shearing place a few drops of oil on the comb and cutter and into
the lubrication hole on top of the handpiece body (illustration 2, item 2).
•Inadequately oiled combs and cutters will overheat and go blunt quickly.
•Oil the combs and cutters at least every 15 minutes.
•Place one drop of oil in the side of the handpiece every 50 sheep
(illustation 2, item 3). Do not exceed this amount.

Fitting the comb and cutter
•Ensure the sharp surfaces come together.
•Loosen the tension nut, slacken off the comb screws and remove the old comb and
cutter.
•Make sure the new comb and cutter are clean. Dirt on the ground surfaces will
cause problems.
•Place the new cutter in the chicken feet’s carrier cones. Push the new comb
between the loosened screws. Tighten the comb screws until you can just move the
comb sideways by hand.
•Adjust the comb until the sharp surface of the comb projects approximately 1.2mm
– 2.0mm beyond the tips of the cutter (note: the cutter must not overhang the
hollows on the ends of the comb teeth).
•Tighten the combs screws. Tighten the tension nut until the cutter is pressed
against the comb and you can feel a slight resistance. Add more tension if it does
not cut cleanly on the first blow.
•Always check that neither of the conical pins has moved out of the holes in the
cutter. Changing Combs and Cutters
•Replace both comb and cutter once they become blunt.
•Re-sharpening can only be done with a special machine.
Cleaning the Air Filter
•Clean the air filter with a dry brush frequently.
•The machine must never be operated with a damaged air filter.
Servicing
•Whenever working on the combs and cutters or the machine, always first disconnect
the power supply.

Care of Combs and Cutters
•Wash used combs and cutters each day
•Left dirty, the salt in sheep grease, and dirt, eats into the metal.
•Once pitted or rusted, it is impossible to get sharp edges again when sharpening.
This pulls on the wool, unsettling the sheep, and makes shearing slower and more
difficult.
Cleaning
•After shearing wash the blunt combs/cutters.
•Use very hot soapy water. Brush to remove all grease, dirt and oil. Rinse in hot
water, and dry immediately.
•Keep in a dry place.
To Post
•Wrap the clean, dry combs and cutters together securely, covering all sharp points,
and preventing any movement.
•Put in a Jiffy bag, or box. Include your name, address and phone number.
•Ask for a ‘Certificate of Posting’ at the Post Office – it is free.
Note: Combs and cutters cannot be sharpened unless free of all dirt and oil.
