Positioning Your Comb and Cutter
Before you start, ensure the comb screws and tension knob
are slack.
Hold the machine so that you are looking at its underside and
so you can clearly see both comb screws.
Place your comb in the
machine so that the sharp side
faces the forks and adjust the
comb until the heel is level
with the back edge of the comb
screws.
DO NOT position the heel of
the comb to the back of the
comb bed.
Tighten the comb screws nger tight, holding the comb in
place. Not too tight, you may need to adjust this further.

Turn over the machine and place your cutter onto the comb.
The sharpened sides of both the comb and cutter should face
each other. Locate the cutter onto the conical pins on the
forks.
Secure the cutter by turning
the tension knob clockwise.
Apply enough tension to
secure the cutter.
Setting the Lead
Adjust the comb so that as the cutter travels over the comb’s
central tooth, at least 1.5 mm of the comb tooth’s at ground
surface is clear of the cutter’s tip.
Finally, rmly tighten the comb screws.

Setting the Throw
It is normal for the clipper forks to lock in position either side
of the throw.
Whichever side the forks are
positioned at, this is the side you
will set the throw from. If the
forks are positioned in the
centre, push your forks to
the right if you are right-handed,
or to the left if you are left-handed.
Adjust the comb so that the outside edge of both the comb and
cutter align. Firmly tighten the comb screws and then turn the
tension knob clockwise to apply tension and secure the cutter
in place.
Setting the Tension
Tighten the tension knob by
turning it clockwise.
Too little tension causes
‘feathering’ which compromises
the quality of the cut.
Too much tension will cause the
comb and cutter to overheat,
resulting in your combs and
cutters becoming blunt faster.

Comb and Cutter Usage
Never increase the tension when the comb or cutter starts to
become blunt as this will damage your equipment. When your
combs and cutters do start to go blunt, change them.
Once blunt, you should have your combs and cutters
sharpened on a specialist grinder.
For professional shearers the recommended cutter to comb
ratio is three cutters to one comb. However, we advise that
general farm shearers can lower that ratio to 2:1.
