HOW TO USE
Q Installation of the solenoid arm
( 1 ) Install the rotary solenoid so that the gap
between the rotary solenoid and the solenoid
arm is about 0 to 0.5 mm.
Note: If the gap is too large, the roller and
the cam follower crank interfere while
rotating movement of the solenoid,
which causes malfunction and result in
failure of the thread trimmer device.
R Removal procedure of the hook
( 1 ) Loosen three set screws of the small gear to
the hook shaft.
( 2 ) Remove the opener.
( 3 ) Remove the fixed knife.
( 4 ) Move the lever to the arrow direction,
and move the movable knife to the arrow
direction.
( 5 ) Remove the hook.
Note: To install the hook, reverse the removing
procedure.
