Hitachi C12FSA instruction manual Cutting large workpieces, Bevel cutting procedures

English

Accordingly, press the handle down gently and carefully.

*In slide cutting, gently push the handle back (rearwards) in a single, smooth opera- tion.

Stopping the handle movement during the cut will cause unwanted cutting marks on the workpiece.

WARNING: * For slide cutting, follow the procedures indicated above in Fig. 21.

Forward slide cutting (toward the operator) is very dangerous because the saw blade could kick upward from the workpiece. Therefore, always slide the handle away from the operator.

*Always return the carriage to the full rear position after each crosscut operation in order to reduce the risk of injury.

*Never put your hand on the side handle during the cutting operation because the saw blade comes close to the side handle when the motor head is lowered.

There may be case when a complete cutting cannot be done depending on the height of workpiece. In this case, mount an auxiliary board with the 6mm flat head screws and the 6mm nuts using the 7mm holes on the fence surface (two holes on each side). (Fig. 22)

Refer to page 9 "SPECIFICATIONS" for the thickness of the auxiliry board.

(1)Loosen the clamp lever and bevel the saw blade to the left or to the right.

When tilting the motor head to the right pull the fixing pin towards the rear.

(2)Adjust the bevel angle to the desired setting while watching the bevel angle scale and indicator, then secure the clamp le- ver.

(3)Follow the procedures indicated in paragraphs 4 and 5 above. For maximum dimensions for bevel cutting, refer to “SPECIFICATIONS” table on page 9.

WARNING: When the workpiece is secured on the left or right side of the blade, the short cut-off portion will come to rest on the right or left side of the saw blade. Always turn the power off and let the saw blade stop completely before raising the handle from the workpiece.

If the handle is raised while the saw blade is still rotating, the cut-off piece may become jammed against the saw blade causing fragments to scatter about danger- ously.

When stopping the bevel cutting operation halfway, start cutting after pulling back the motor head to the initial position.

Starting from halfway, without pulling back, causes the safety cover to be caught in the cutting groove of the workpiece and to contact the saw blade.

CAUTION: When cutting a workpiece of 2-15/16" (75mm) height in the left 45° bevel cutting position or a workpiece of 1-3/4" (45mm) height in the right 45° bevel cutting position, adjust the lower limit position of the motor head so that the gap between the lower edge of the motor head and the workpiece will be 5/64" to 1/8" (2 to 3mm) at the lower limit position (refer to “3. Checking the saw blade lower limit position” on page 14).
