Adjustment Of Laser Marker Accuracy - Hitachi C 12LSH Technical Data And Service Manual

11-10. Adjustment of Laser Marker Accuracy

(1) Construction of laser marker and functions of each component
The Adjuster [191] located at the side of Hinge (A) [173] is a screw used for moving the Laser Marker [198A]
horizontally. The laser line can be aligned with the left side of the cutting width (saw blade) or the ink line on
the right side by means of the Adjuster [191]. The accuracy of the Laser Marker [198A] is adjusted by the two
Seal Lock Hex. Socket Set Screws M5 x 6 [200]. The Seal Lock Hex. Socket Set Screw M5 x 6 [200] located
at the front is mainly used for adjusting the squareness with the fence surface. The Seal Lock Hex. Socket Set
Screw M5 x 6 [200] located under the Laser Marker [198A] is mainly used for adjusting the squareness with
the base surface (Fig. 75-a). The laser line will shift to the right in parallel when the Adjuster [191] is turned
clockwise, and shift to the left when turned counterclockwise.
CAUTION: Exercise utmost caution in handling a switch trigger for the position adjustment of the
laser line, as the power plug is plugged into the receptacle during operation. If the switch
trigger is pulled inadvertently, the saw blade can rotate and result in unexpected accidents.
Do not stare into beam while the laser marker is lighting.
Do not observe beam directly with an optical instrument.
If your eye is exposed directly to the laser beam, it can be hurt.
Instruct the customer not to stare into beam. In addition, instruct the customer not to give
strong impact to the laser marker (main body of tool) and not to dismantle the laser
marker.
Use of controls or adjustments or performance of procedures other than those specified in
this TECHNICAL DATA AND SERVICE MANUAL and the Instruction Manual may result in
hazardous radiation exposure.
