CAUTION:

When the workpiece is secured on the left side, the cut-off

portion comes to rest on the side of the saw blade as illustrated

in Fig. 23. If the handle is raised before the saw blade rotation

comes to a complete stop, there is a chance that the cut-off

portion of the workpiece could become jammed against the

saw blade, causing a hazardous condition. Instruct the

customer to ensure without fail that the saw blade comes to a

complete stop before attempting to raise the handle.

8-5. Cutting Operation

(1) Cutting efficiency will be reduced if a dull saw blade is used, if an excessively long extension cord is used, or if

the wire gauge of the extension cord is too small. (For details on extension cords, please refer to the

Instruction Manual.) This is particularly important when cutting materials with dimensions which are at or near

the maximum capacity for the machine.

(2) The customer should be advised to thoroughly inspect the workpiece to ensure that there are no metallic

objects (nails in particular), sand, or other foreign matter in or on the workpiece. Saw blade contact with such

foreign matter will not only shorten the service life of the saw blade, but could cause serious accident. Should

the saw blade tips be broken off, the tips may fly toward the operator.

(3) Direct current cannot be used. The switch can be faulty if used.

(4) Press cutting

The Models C 12LDH and C 12FDH can be used for press cutting of workpieces up to 70 mm x 203 mm

(2-3/4" x 8") in a single operation by simply pushing the saw blade section (head) downward.

The customer should be cautioned that excessive pressure on the handle will not increase the cutting speed.

On the contrary, excessive pressure may result in reduced cutting efficiency (irregular or rough cutting of the

workpiece), and could also cause overload and subsequent burnout of the motor.

On completion of the cutting operation, turn the switch OFF and wait for the saw blade to come to a complete

stop before raising the saw blade section (head) to its original position. Raising the saw blade section (head)

while the saw blade is rotating may cause unwanted cutting marks on the workpiece.

Techniques to avoid unwanted cutting marks

Uneven and unwanted cutting marks can be avoided throughout the cutting operation by gently and smoothly

pressing down on the handle, so that the entire cutting operation is accomplished in a single uninterrupted

motion.

(5) Miter cutting

Miter cutting is accomplished by turning the table. (For details, please refer to the Instruction Manual.)

(6) Bevel cutting

Bevel cutting of 0 --- 45˚ to the left/right is accomplished by inclining the saw blade section (head). (For details,

please refer to the Instruction Manual.)
