Hitachi C 12LSH, C 12RSH manual 19

Position crown molding with its WALL CONTACT EDGE against the guide fence and its CEILING CONTACT EDGE against the crown molding Stoppers as shown in Fig. 50-b. Adjust the crown molding Stoppers according to the size of the crown molding.

Tighten the 6mm wing bolt to secure the crown molding Stoppers.

Refer to the lower table for the miter angle.

Grooves in the workpiece can be cut as indicated in Fig. 51 by adjusting the 6 mm depth adjustment bolt.

Cutting depth adjustment procedure:

(1)Turn the stopper holder on the direction shown in Fig. 52.

Lower the motor head, and turn the 6 mm depth adjustment bolt by hand. (Where the head of the 6 mm depth adjustment bolt contacts the hinge.)

(2)Adjust to the desired cutting depth by setting the distance between the saw blade and the surface of the turntable (see b in Fig. 51).

NOTE

When cutting a single groove at either end of the workpiece, remove the unneeded portion with a chisel.

14.Cutting easily-deformed materials, such as aluminum sash

Materials such as aluminum sash can easily deform when tightened too much in a vise assembly. This will cause inefficient cutting and possible overload of the motor.

When cutting such materials, use a wood plate to protect the workpiece as shown in Fig. 53-a. Set the wood plate near the cutting section.

When cutting aluminum materials, coat the saw blade with cutting oil (non-combustible) to achieve smooth cutting and a fine finish.

In addition, in case of a U-shaped workpiece, use the wood plate as shown in Fig. 53-bto ensure stability in the lateral direction, and clamp it near the cutting section of the workpiece and tighten it using both the vise assembly and the clamp available in the market.

15. How to use the dust bag (Standard accessory)

(1)When the dust bag has become full of sawdust, dust will be blown out of the dust bag when the saw blade rotates.

Check the dust bag periodically and empty it before it becomes full.

(2)During bevel and compound cutting, attach the dust bag at a right angle to the base surface as shown in Fig. 54.
