Fix shaped steel as shown in Fig. 11-(a), (b), (c).
Do not fix shaped steel as shown in Fig. 12-(a).
If it is, the workpiece will move and cutting
accuracy will deteriorate.
(3) Fix flat-bar steel as shown in Fig. 11-(d). but,
hight of workpiece is less than 100mm. (Figs.
11 and 12).
Ensure that the workpiece is securely fastened with
the vise. If it not, a serious accident could be caused
if the workpiece comes loose or the saw blade
breaks during operation.
Do not fix flat-bar steel as shown in Fig. 12-(b).
Improper fixing of the workpiece material may cause
the carbide tipped to abrade and make a crack
during cutting, causing damage to the blade.
(1) After turning on the trigger switch and checking
that the saw blade is rotating at full speed,
slowly push down the handle while holding
down the lever and bring the equipment in the
vicinity of the workpiece.
(2) When the saw blade contacts the workpiece,
push the handle down gradually to produce
(3) When the cutting (or desired cutting-in) has been
completed, raise the handle up to the retract
(4) Turn off the trigger switch after each cutting
operation is completed, and allow the saw blade
to come to a complete stop before preparing for
the next operation.
Be sure to wear protective goggles-while cutting.
Slowly bring the saw blade into contact with the
workpiece. Do not move the blade suddenly.
Increased pressure on the handle does not
necessarily mean faster cutting of the work-piece.
On the contrary, too much force may result in
overload of the motor and/or decreased cutting
While cutting, the tip will wear down slightly, but
this will not adversely affect cutting ability. Continue
to use as is. However, when cracks appear on the
metallic block immediately stop using the saw blade.
When the saw blade ceases to work during cutting,
immediately turn off the trigger switch and remove
the saw blade from workpiece. Afterwards, check
for problems by no load test operation without any
When the material that is to be cut off and discarded
is thin or narrow, if after cutting the handle is lifted
while the saw blade continues to rotate, this scrap
may fly out when it comes into contact with the
rotating saw blade and cause injury. Return the
handle to its original position after the saw blade
has completely stopped moving.
When the cutting is stopped in the middle of a job,
lift the handle as the saw blade continues to rotate.
Ensure the trigger switch is turned OFF and the plug
is removed from the power outlet when work has
Do not touch the material around the region where
it has been cut with unprotected hands. It is very
5. Cutting at angles
(1) It is possible to cut at angles up to 45 degrees.
Untighten the three M10 bolts with the wrench
that comes with the saw blade and set the angle
of vice (B) in alignment with the angle on the
indicator. (Fig. 5)
(2) Make sure to tighten the three M10 bolts securely
after setting the angle.
(3) Untighten the two wing bolts and move the side
cover so that it is in alignment with the angle
set. (Figs. 1 and 6)
MOUNTING AND DISMOUNTING SAW
First, disconnect plug from receptacle.
1. Dismounting Saw Blade. (Figs. 7, 8 and 9)
(1) Lift the safety cover until it touches the hexagonal
socket head bolt.
(2) Press in spindle lock, and loosen bolt with
If the spindle lock cannot be easily pressed in
to fix the saw blade spindle, turn the bolt by
wrench while applying pressure on the spindle
The saw blade spindle is fixed when the spindle
lock is pressed inward.
(3) Removing the bolt, washer (B) and the saw
Be very careful when removing the saw blade after
it has been used for cutting several materials in
succession, since the blade may be very hot.
2. Mounting Saw Blade.
(1) Attach the saw blade.
When mounting the saw blade, make sure the
rotation indicator mark on the saw blade and the
rotation direction are properly matched.
(2) Thoroughly clean washer (B) and the bolt, and
install them onto the saw blade mounting shaft.
(3) Press the spindle lock and tighten the bolt with
Make sure the spindle lock has returned to the
retract position after installing or removing the saw
Tighten the bolt so it doesn't come loose during
Check that the bolt is properly tightened before the
Power tool is started.
MAINTENANCE AND INSPECTION
Prior to inspecting the dry cut metal saw be sure to
disconnect the power plug.
1. Inspecting the saw blade.
Since use of a dull saw blade will degrade efficiency
and cause possible motor malfunction, sharpen or
replace the saw blade as soon as abrasion is noted.
