Cutting Procedures; Mounting And Dismounting The Cut-Off Wheel - Hitachi CC 14SF Handling Instructions Manual

CUTTING PROCEDURES

CAUTION
It is dangerous to remove or install the workpiece while the cut-off wheel turning.
1. Operating the switch
The switch is switched on by manually pulling the trigger and cut off by releasing the trigger
to the original location. The switch can operate continuously, even after releasing the
trigger, by pushing the stopper after pulling the trigger. The stopper can be removed by
pulling the trigger again and the switch is cut off with the release of the trigger.
2. Cutting
(1) Rotate the cut-off wheel, gently press down the handle, and bring the cut-off wheel close to
the cutting material.
(2) When the cut-off wheel contacts the cutting material, gently press down the handle further
and start cutting.
(3) When cutting (or designated slotting) is completed, raise the handle and restore it to its
original position.
(4) At the termination of each cutting process, turn OFF the switch to stop rotation and proceed
with the subsequent cutting job.
CAUTION
It does not necessarily cut rapidly when putting more force on the handle.
Too much force on the handle will put excessive pressure on the motor and reduce
its capacity.
Do not fail to switch OFF the switch after operation is completed and pull the plug
out.
