HOW TO USE
CAUTION:
If the tipped saw blade stops suddenly, makes an
abnormal sound, etc., immediately turn off the
switch.
Do not use cutting oil on the blade.
Such substances as cutting oil, polishing oils and
waxes can catch fire from sparks when cutting.
When using the metal cutter, always wear eye
protection.
Be sure that the materials are secured firmly in
position. If the materials are not properly secured
in position, they may fly about causing damage to
the tipped saw blade.
When cutting is finished, immediately turn off the
power and unplug the metal cutter.
Be careful as not to cut the unit cord with the
rotating tipped saw blade.
Discard cutting dust before the dust cover becomes
completely full.
If the metal cutter is used when the cutting dust
is pressed against the dust cover, the performance
of the dust collector will drop and the temperature
of the dust cover (B) will rise. This may cause dust
cover (C) to warp or melt.
Wear ear plugs to protect ears from effects of the
sound.
If the cutting depth adjustment is too shallow, the
cut may tend to open lowering the performance of
the cutting dust collector.
When cutting the surface of a wall, the rate of
accumulation of cutting dust inside the dust cover
may change and may lower the performance of the
cutting dust collector.
Use a tipped saw blade that is suitable for the
material being cut.
When cutting, push the blade straight and forward
without letting the blade curve to the left and right.
Push the blade forward slowly, especially when
beginning to cut and when coming to the end of
the cut.
Do not turn on the metal cutter with the blade
pressed against the cutting material. Do not turn
off the metal cutter in the midst of cutting a piece
of material. In a case where it is absolutely necessary
to turn the metal cutter off in the middle of cutting
a work piece, pull the chip saw back with the blade
still turning and after it is no longer in contact with
the work piece material, then turn the power switch
off.
Do not to try to cut the same work piece two times
in the same location.
1. Place the main body (base) on the surface of the
work piece and align the slit on the forward edge
of the base with the sighting line. The arrow mark
on the gear cover and the slit in the base will be
aligned and can be used for positioning the metal
cutter. (See Fig. 4)
2. Without allowing the blade to touch the material,
~~~~~~~~~~~~~~~~~~~~~~~~~
turn on the power switch. When the blade has
~~~~~~~~~~~~~~
attained its maximum speed, push the metal cutter
slowly forward and maintain the same speed until
the cut is completed.
To keep the cut clean, push the saw forward at the
same speed.
3. The slit in the base indicats the position of the edge
of the blade at further end of the cut. This is useful
when cutting the work piece to a mid-way point.
(See Fig. 5)
4. The power switch is turned on by pulling the trigger.
When the "Stopper" switch is pushed (See Fig. 6),
the saw will remain running even if the finger is
removed from the trigger. This is a convenient
feature when using the saw for continuous work.
When the trigger is pulled a second time, the
"Stopper" switch is turned off and the saw is
stopped.
ATTACHING AND REMOVING BLADES
CAUTION:
Always turn the power switch off first and remove
the plug from the socket.
Use the spanner and box wrench that are supplied
with the metal cutter. Do not use other tools as this
may result in over-tightening or in sufficient
tightening of the wing bolt that holds the blade in
place causing accidents.
1. Removing the blade
(1) Loosen the two wing bolts and remove dust covers
(A) and (B). (See Fig. 7).
(2) Adjust the cutting depth of the blade to the minimum
position and place the tipped saw cutter on a flat,
stable surface. (See Fig. 8).
(3) While pushing in the lock lever, slowly unscrew the
bolt using the box wrench provided.
(4) Holding the spindle in position, turn the box wrench
counter-clockwise and remove the bolt and the
washer (B).
(5) Remove the tipped saw blade in direction (A).
2. Attaching the blade
CAUTION:
After using the tipped saw blade, dust covers (A)
and (B) may become hot. Take caution when
handling.
Do not forget to use the distance piece.
Before plugging in the metal cutter, be sure to
check to see whether the lock lever has been returned
to its original position and that the tipped saw blade
can rotate smoothly.
(1) Follow the blade removal routine in reverse.
(2) Remove any cutting dust that may have adhered
to the spindle or the washers.
(3) When a chip saw blade with a 20mm diameter is
to be attached, place washer (A) with the shallow
recessed portion turned toward the blade side.
When the hole diameter is 19mm, place the side
of washer (A) with the more deeply recessed portion
toward the blade.
For both cases, the (B) washer is used with its
recessed portion facing toward the blade. (See
Fig. 9)
(4) Make sure that the arrow mark on the side of the
blade is aiming the direction as the direction of
arrow on the gear cover. (See Fig. 10)
(5) Be sure to tighten the bolt sufficiently.
