III. Installation
3.1 Installing combs and cutters
3.1.1 Combs
Place the comb on the cutting head of the handpiece, make sure the comb and the
cutting head is properly aligned and symmetrical. At this stage do not tighten the
comb screw, apply limited pressure just enough to hold the comb in place.
3.1.2 Cutters
Insert cutter then tighten the tension nut, until the tips of the chickenfeet fit firmly into
the two holes on both sides of the cutter.
3.1.3 Adjusting and securing comb
Adjust the relative positions of the comb and cutter, ensure the point at which the
bevel of the comb begins is 1.5 to 2 mm from the tip of the middle tooth of the cutter
(see fig.1). Also ensure that the comb and cutter is symmetrically positioned, then
secure the comb firmly using the provided spanner.

3.2 Comb selection
Choosing the right comb for the job is a vital part of preparation for shearing.
Selection of comb should consider shape of the tip, bevel and width. (see fig. 2)
Fig. 2
In general:
•Short bevel is principally used when shearing is at its best and the stock are in
top condition.
•Medium bevel is the most widely used comb and suitable for the majority of
crossbred shearing.
•Long bevel is particularly suitable for fine wool sheep when the wool is dense
and sticky.
Width selection should take into account the user’s level of experience with shearing.

3.3 Chickenfeet
Before mounting chickenfeet, apply a small amount of grease to the two mounting
holes on the forkbody, then insert the left and right chickenfeet into the left and right
holes respectively, make sure the safety spring falls into the groove of the
chickenfeet.
To take out the chickenfeet, twist the chickenfeet 180° then pull outward.
The chickenfeet is secured onto the forkbody by a safety spring, ensure the screw
holding the safety spring in place is not loose.

3.4 Remove and replace the fork body assembly and the roller
3.4.1 Method of removal
The fork body assembly can be removed without removing the center post.
First unscrew the tension nut, then remove the tension pin and tension sleeve.
Remove the safety screw behind the tension nut and remove the fork body with the
roller attached.
3.4.2 Replacing fork body
Remove the oil hole cap on the top of the handpiece. Place a small amount of
grease onto the roller (ball) and ball race of the fork body. Place the ball onto the
crankshaft using a pen, screwdriver or other suitable method (make sure that the flat
side of the roller is facing the crank spindle). Place the crank and roller in the bottom
position in the handpiece. Insert the fork body from the front of the handpiece and
over the ball. After it is confirmed that the center post cup is sitting onto the center
post correctly, replace and tighten the safety screw.
3.5 Adjusting center post
The center post has been adjusted to the correct position when leaving the factory, it
can suit cutters of different thicknesses. Do not re-adjust the center post unless
necessary.
If adjustment is necessary, first, use a worn cutter (approx.. 3.5mm in thickness), and
a comb of any thickness, set the comb in place (see adjusting and securing comb
above), then adjust the roller on the crank spindle to the highest position.
3.5.1 Adjusting roller to the highest position
(1) first remove the cover cap on top of the handpiece, check to see if the roller is
positioned at the top of the groove of the fork body. If its position is at the top, go to
step (3).
(2) If the roller is not positioned at the top of the groove on the fork body, then start
and stop the handpiece, until the roller is positioned at the top of the groove.
Caution: before starting the machine, ensure the comb and cutter are fitted
and tension applied.
(3) With the roller positioned at the top, turn off the power supply, disconnect the
cord between the handpiece and power supply.
Caution: before carrying out repair work, ensure power is disconnected!
(4) Loosen tension, hold the front of the fork body and move horizontally back and
forth, until the roller is at its highest position. (Note: use care when adjusting the

Page 7of 17
forkbody, excessive movement may cause the roller to slide down, if this happens,
repeat step (2).
3.5.2 Adjusting center post
Loosen the center post nut and insert the post gauge as per illustration, keeping it at
90 degrees to the handpiece. Turn the center post until the center of the gauge is
level with the gauge top. Retighten the center post nut (Fig).
Fig.3
3.6 Adjusting tension
3.6.1 Installing tension retaining spring
When installing, first make sure that the larger curved tip of the spring points to the
clockwise direction (viewed from the top) as it is inserted into the thread bush, then
insert the smaller curved tip into the small hole. Apply force to press the retaining
spring into the grooves of the thread bush.
Caution: not installing the tension retaining spring could cause loss of tension
capacity, resulting in damage to the handpiece!
3.6.2 Tension problems
Be aware that the size of each end of the tensioning pin is different, ensure the
larger end sits in the tension pin cup. Also ensure that the downward tips of the
chickenfeet are pressed firmly into the holes on the cutter. To apply tension,
smoothly rotate and tighten the tension nut. Do not apply too much pressure as it
may cause overheating and accelerate blade wear. When cutting is not smooth, first
check the sharpness of the blades.
Caution: the downward tips of the chickenfeet must be pressed firmly into the
holes on the cutter, otherwise tension cannot be applied properly.

IV. Operation
4.1 Pre-work inspection and preparation
(1) Check that the comb and cutter are properly installed, and tension is correct.
(2) Check if the gearbox has been greased as required, other lubricated parts have
been greased as required.
(3) Check if the voltage of the main power supply and the special power supply
(Controller) for the handpiece is correct.
4.2 Pre-use and in-use safety and precautions
(1) The power outlet must be reliably grounded.
(2) Before turning on the power, the switche on the handpiece must be set to OFF.
(3) After the power is connected, with the handpiece in hand, turn on the switch at
the back of the handpiece.
(4) During shearing, the cutting head of the handpiece should always maintain a safe
distance from the operator.
(5) During shearing, the lead of the handpiece should be kept free and unobstructed
to avoid tangling with sheep.
(6) While on break, the handpiece should be turned off to prolong its service life.
(7) Keep the vents of the handpiece motor free from blockage, any wool or debris
blocking the vents should be promptly removed.
(8) If a problem occurs during shearing, first shut off the handpiece and cut off the
power supply, then proceed to perform inspection and maintenance.
(9) Ensure the handpiece is turned off and the power is cut off before loosening the
tension nut.
(10) Do not turn on the handpiece without first installing the comb and cutter.
Caution: power must be completely unplugged before performing maintenance
on the handpiece!
4.3 Using the handpiece
(1) Plug in the power cord into the power supply and ensure it is secure.
(2) Hang or fix the control box at a height of approximately 1.4 –1.7 meters above
ground.
(3) Connect the control box to the main power supply with its 3 points plug.
(4) To start or halt operation, use the switch located at the back of the handpiece.
Caution: the handpiece must be started under zero load before every
operation.

Caution: in the event that an emergency stop is required ( e.g. sheep tangling),
press the button and pull out the plug at the bottom of power supply.
