Fixing comb
Slacken comb screws (3). Slip comb (1) behind screws, so that the
comb is parallel to the heel of the handpiece, sharp face upwards.
(4)
Tighten comb screws, finger tight at this stage, as any adjustment
can only be made by moving the comb.
Fit Cutter
The pins on the outside of the fork prongs locate in the tiny holes
on ends of the outside teeth of the cutter (7). Slacken tension
knob, fit the cutter, sharp face down, on to sharp face of comb.
(6). Screw down the tension knob until gentle pressure is felt.
Setting Lead fig. 2
The cutter must NOT overlap the hollows at the ends of the teeth.
Adjust comb forward so that at least 1.5mm of the sharp tooth can
be seen between the front of the cutter and start of the hollows on
the comb.
Setting Throw fig. 4
Adjust the comb left or right, so that the cutter does not go beyond
the outside tooth (right side for right-handed person). Check lead
again. Tighten comb screws firmly with screwdriver.
Check the fork pins are still seated in the cutter holes.
Tension
Screw down tension knob, until the drive cogs can just be turned
with thumb. Never slacken tension while machine is running.
Too little tension - "feathering" i.e. not a clean cut occurs.
Too heavy tension - overheating occurs- blunting combs and
cutters.
Never screw down tension when combs start to go blunt, always
change a cutter, or both comb and cutter.
Sharpening
Wash blunt combs/cutters each night, rinse off and dry well. Send
off for sharpening. Store in oil.
Do not dip the handpiece in water during shearing.
