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

(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
