GENERAL OPERATIONAL PRECAUTIONS
WARNING! When using electric tools, basic safety
precautions should always be followed to reduce the risk
of fire, electric shock and personal injury, including the
following.
Read all these instructions before operating this product
and save these instructions.
For safe operations:
1. Keep work area clean. Cluttered areas and benches
invite injuries.
2. Consider work area environment. Do not expose
power tools to rain. Do not use power tools in
damp or wet locations. Keep work area well lit.
Do not use power tools where there is risk to
cause fire or explosion.
3. Guard against electric shock. Avoid body contact
with earthed or grounded surfaces. (e.g. pipes,
radiators, ranges, refrigerators).
4. Keep children away. Do not let visitors touch the
tool or extension cord. All visitors should be kept
away from work area.
5. Store idle tools. When not in use, tools should
be stored in a dry, high or locked up place, out
of reach of children.
6. Do not force the tool. It will do the job better and
safer at the rate for which it was intended.
7. Use the right tool. Do not force small tools or
attachments to do the job of a heavy duty tool.
Do not use tools for purposes not intended; for
example, do not use circular saw to cut tree limbs
or logs.
8. Dress properly. Do not wear loose clothing or
jewelry, they can be caught in moving parts.
Rubber gloves and non-skid footwears are
recommended when working outdoors. Wear
protecting hair covering to contain long hair.
9. Use eye protection. Also use face or dust mask
if the cutting operation is dusty.
10. Connect dust extraction equipment.
If devices are provided for the connection of dust
extraction and collection facilities ensure these are
connected and properly used.
11. Do not abuse the cord. Never carry the tool by
the cord or yank it to disconnect it from the
receptacle. Keep the cord away from heat, oil and
sharp edges.
12. Secure work. Use clamps or a vise to hold the
work. It is safer than using your hand and it frees
both hands to operate tool.
13. Do not overreach. Keep proper footing and balance
at all times.
14. Maintain tools with care. Keep cutting tools sharp
and clean for better and safer performance. Follow
instructions for lubrication and changing
accessories. Inspect tool cords periodically and if
damaged, have it repaired by authorized service
center. Inspect extension cords periodically and
replace, if damaged. Keep handles dry, clean, and
free from oil and grease.
15. Disconnect tools. When not in use, before servicing,
and when changing accessories such as blades,
bits and cutters.
16. Remove adjusting keys and wrenches. Form the
habit of checking to see that keys and adjusting
wrenches are removed from the tool before turning
it on.
17. Avoid unintentional starting. Do not carry a
plugged-in tool with a finger on the switch. Ensure
switch is off when plugging in.
18. Use outdoor extension leads. When tool is used
outdoors, use only extension cords intended for
outdoor use.
19. Stay alert. Watch what you are doing. Use common
sense. Do not operate tool when you are tired.
20. Check damaged parts. Before further use of the
tool, a guard or other part that is damaged should
be carefully checked to determine that it will
operate properly and perform its intended function.
Check for alignment of moving parts, free running
of moving parts, breakage of parts, mounting and
any other conditions that may affect its operation.
A guard or other part that is damaged should be
properly repaired or replaced by an authorized
service center unless otherwise indicated in this
handling instructions. Have defective switches
replaced by an authorized service center. Do not
use the tool if the switch does not turn it on and
off.
21. Warning
The use of any accessory or attachment, other
than those recommended in this handling
instructions, may present a risk of personal injury.
22. Have your tool repaired by a qualified person.
This electric tool is in accordance with the relevant
safety requirements. Repairs should only be carried
out by qualified persons using original spare parts.
Otherwise this may result in considerable danger
to the user.
PRECAUTIONS ON USING METAL CUTTER
1. Always use the correct electric power source
voltage which is indicated on the name plate on
the metal cutter.
2. Do not fix the protective cover permanently in
place so that it does not move. Check to see that
it moves smoothly.
3. Use the tipped saw by following the use limitations
indicated on the name plate.
Do not use a tipped saw with bottom blade
diameter of 165 mm or less.
4. Place the materials to be cut on a stable table or
bench.
5. Just before and after the piece has been cut all
the way through, be sure the tipped saw blade
does not get caught between the two pieces
because of the weight of the cut off portion of
the material. Prevent this by supporting the piece
being cut off by placing it on a table or bench.
6. If the piece being cut off is large, support it by
using a stable table or bench. If the cut is to be
made on a work piece lying on a flat surface, keep
the tipped saw blade from touching the surface
below and causing the saw to move by making
sure that the height of the work piece is elevated
above the surface under the work piece at least
three times the distance that tipped saw blade
projects from the saw.
3
7. When cutting, hold the body of the metal cutter
firmly.
8. While using the metal cutter, keep the tipped saw
blade, rotating parts and the saw dust exit aperture
away from the hands and face.
9. When making a cut, do not try to pull the metal
cutter out of the cut while it is running. Turn off
the power switch first and wait until the blade
completely stops rotating before taking the metal
cutter out of the cut.
10. If the tipped saw does not seem to operate
normally or makes abnormal sounds, stop using
the tipped saw immediately and contact an
and repair.
11. If the metal cutter is accidentally dropped or
bumped, carefully examine the frame, tipped saw,
etc. to see that there are no cracks, deformation
or any other damage.
12. Make sure that material to be cut is firmly fixed
in place.
13. Keep flaminable and easily damaged objects away
when cutting metal.
14. Do not use the metal cutter to cut hard metal
materials for long continuous periods of time.
15. Do not use cutting oil when cutting materials with
the metal cutter.

PRIOR TO OPERATION
1. This product has double insulation. However, to
avoid electric shocks, be sure to use a power
source that is equipped with a circuit breaker to
cope with power leakage and sudden surges.
2. Power source
Ensure that the power source to be utilized
conforms to the power requirements specified on
the product nameplate.
3. Power switch
Ensure that the power switch is in the OFF position.
If the plug is connected to a receptacle while the
power switch is in the ON position, the power tool
will start operating immediately, inviting serious
accident.
4. Extension cord
When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
5. Preparing a wooden work bench
The outer edge of the
tipped saw blade projects
Work piece to be cut
Work
bench

from the bottom of the
work piece being cut.
Vise
Therefore, the material
should be placed on a work
bench when cutting.
In addition, care should be
taken to see that the tipped
saw blade and protective
cover do not come into
Work piece

Projection
distance of
the tipped
saw blade
contact with the surface
below the work piece (e.g.,
the surface of the work
bench or the ground, floor,
etc.). To make sure that this
does not happen, the work
piece (material to be cut)
should be at a height above
the surface below the work
piece that is equal to at
least three times the
distance (width) that the
blade projects below the
bottom of the work piece.
In situations like this, it is safer to make sure that
the material is firmly secured in place using a vise
so that both hands can be used to operate the
metal cutter.
If the piece to be cut off is large in size, care must
be taken to see that the weight of the piece being
cut off does not press on the saw blade. To
prevent the saw blade from being caught between
the two pieces, the piece being cut off should be
supported using a stable bench or braced in place
using wooden supports.
If separate wooden supports are to be used to
support the piece being cut off, when cutting at
a work bench, they should be positioned on a flat
surface and fixed in place. It is dangerous to allow
the work bench to wobble or shift position while
cutting materials with the metal cutter.
6. Checking to see that the tipped saw blade is
attached firmly in position
Always check to see that the tipped saw blade
is attached firmly in position. For details, see Page
7: “Attached and removing the tipped saw blade”.
7. Check the lever to see that is properly tightened.
Insufficient tightening of the cutting adjustment
lever may cause personal injury (See Fig. 2).
Be sure to check that it is firmly tightened.
8. Attaching the side handle
Attach the side handle by screwing it in place in
the socket located on the gear cover. (See
Fig. 1)
