Assembly/Disassembly
1) Fitting of the gear shaft complete to shear blade assembly
Center the long hole of the shear blades A,B with the
round hole of the guide plate. Center the two crank
plates with that center as shown in the right sketch. Set
ball bearing 6002 and shear blades A,B face to face.
After assembling, check if the shear blades A,B move
smoothly by turning the gear by hand.
Shear blades
The blade A and the blade B have the same weight so that the vibration of the repeated movement can be offset.
Therefore, when there is an inequality of weight due to grinding or breakage of a blade, vibration of the body
becomes big in proportion to the imbalance. In such a case the shear blade assembly should be replaced.

Operation Mode
(1) Switch operation
Two different switches should be activated to start
operation because this tool has adopted double hand
switch mechanism. For activation, the main switch on the
grip should be pulled by one hand and the loop-shaped
sub switch on the handle held by the other. If either of the
two switches is released, the machine will stop.
