Hitachi C12LCH [18/98] English

English

(2) Align the main unit angle with the tilt angle (0°) and

miter angle (0°) and hold down their reset buttons for

at least 0.2 second.

(3) Turning on the laser marker switch while the digital

display switch is on, lights up the laser marker. (On

the C12FCH, only the laser marker switch.)

CAUTION

䡬 When operating the digital panel, have the motor head

section at the top limit position and the blade stopped.

䡬 If the figure shown on the miter angle digital display

is different from the positive stop angle (for example,

45.0° → 45.5°, 31.6° → 32.0°) then the positive stop

has probably deviated slightly from its correct

position. If this happens, do as follows.

(1) Move the turntable left and right with the side

handle loosened, and set the turntable to the

correct position.

(2) If the figures on the display and positive stop still

do not match, then return the turntable to the 0°

position. Next move the turntable left and right

with the side handle loosened as shown in Fig.

19. After setting it to the correct position 0°, press

the reset button again.

NOTE

䡬 Before starting to cut, align the main unit to the miter

angle 0° and the bevel angle 0° and hold down the

reset buttons for at least 0.2 second. If you press the

digital display switch to ON without aligning the main

unit to 0°, then the figures appearing on the digital

display and the main unit angle will not match.

䡬 The laser marker will not light up if the digital display

switch is turned off. (only on C12LCH)

䡬 Do not use the main unit near equipment that

generates electrical noise such as generators.

Electrical noise might cause faulty readings or

operation on the digital display.

9. Cutting operation

(1) As shown in Fig. 20 the width of the saw blade is the

width of the cut. Therefore, slide the workpiece to the

right (viewed from the operator’s position) when

length

is desired, or to the left when length is

desired.

(Only Model C12LCH/C12FCH)

If a laser marker is used, align the laser line with the

left side of the saw blade, and then align the ink line

with the laser line.

(2) Once the saw blade reaches maximum speed, slowly

push down the handle while pushing the lock lever

(D) and bring the saw blade in the vicinity of the

material to be cut.

(3) Once the saw blade contacts the workpiece, push the

handle down gradually to cut into the workpiece.

(4) After cutting the workpiece to the desired depth, turn

the power tool OFF and let the saw blade stop

completely before raising the handle from the

workpiece to return it to the full retract position.

CAUTION

䡬 For maximum dimensions for cutting, refer to

“SPECIFICATIONS” table.

䡬 Increased pressure on the handle will not increase the

cutting speed. On the contrary, too much pressure

may result in overload of the motor and/or decreased

cutting efficiency.

䡬 Confirm that the trigger switch is turned OFF and the

power plug has been removed from the receptacle

whenever the tool is not in use.

䡬 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 dangerously.

䡬 Every time one cutting of deep-cutting operation is

finished, turn the switch off, and check that the saw

blade has stopped. Then raise the handle, and return

it to the full retract position.

䡬 Be absolutely sure to remove the cut material from

the top of the turntable, and then proceed to the next

step.

10. Miter cutting procedures

(1) Loosen the side handle and push the lever for angle

stoppers. Then, adjust the turntable until the indicator

aligns with desired setting on the miter scale (Fig. 21).

(2) Re-tighten the side handle to secure the turntable in

the desired position.

NOTE

䡬 Positive stops are provided at the right and left of the

0° center setting, at 15°, 22.5°, 31.6° and 45° settings.

Check that the miter scale and the tip of the indicator

are properly aligned.

䡬 Operation of the saw with the miter scale and indicator

out of alignment, or with the side handle not properly

tightened, will result in poor cutting precision.

CAUTION

䡬 Never remove the side handle; use of the tool without

it would be hazardous.

To prevent an accident or personal injury always firmly

tighten the miter handle.

11. Bevel cutting procedures (Fig. 22)

(1) Loosen the clamp lever and bevel the saw blade to

the left.

(2) Adjust the bevel angle to the desired setting while

watching the bevel angle scale and indicator, then

secure the clamp lever.

WARNING

䡬 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 dangerously.

䡬 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.

12. Bevel angle fine adjustment (Fig. 23 and Fig. 24)

(1) Grip the handle on the motor head and position it at

the bevel angle you need. Temporarily tighten the

clamp lever.

CAUTION

䡬 If not tightened firmly enough the motor head might

suddenly move or slip, causing injuries. Be sure to

tighten the motor head section enough so it will not

move.

(2) Make fine adjustments to the bevel angle by gripping

the handle and moving the knob (A).
