SAFETY INSTRUCTIONS FOR METAL
CUTTING SAWS
1. Metal cutting saws are intended to cut ferrous
material, they cannot be used with abrasive cut-
off wheels for cutting ferrous material such as
bars, rods, studs, etc. Abrasive dust causes mov-
ing parts such as the lower guard to jam. Sparks
from abrasive cutting will burn the lower guard and
other plastic parts.
2. Regularly clean the power tool's air vents. The
motor's fan can draw the dust inside the housing and
excessive accumulation of powdered metal may
cause electrical hazards.
3. Wear personal protective equipment. Depending
on application, use face shield, safety goggles
or safety glasses. As appropriate, wear dust
mask, hearing protectors, gloves and shop
apron capable of stopping small fragments. The
eye protection must be capable of stopping flying
debris generated by various operations. The dust
mask or respirator must be capable of filtrating parti-
cles generated by your operation. Prolonged expo-
sure to high intensity noise may cause hearing loss.
4. Do not operate the metal cutting saw near flam-
mable or combustible materials. Sparks and/or
hot debris during cutting operation could ignite these
materials.
5. Always use clamps to support the workpiece.
Never support the workpiece by hand. Do not
use this saw to cut pieces that are too small to
be securely clamped. If your hand is placed too
close to the saw blade, there is an increased risk of
injury from blade contact.
6. The workpiece must be stationary and clamped
using the vise. Do not feed the workpiece into
the blade or cut "freehand" in any way. Unre-
strained or moving workpieces could be thrown at
high speeds, causing injury.
7. Never cross your hand over the intended line of
cutting either in front or behind the saw blade.
Supporting the workpiece "cross handed" i.e. hold-
ing the workpiece to the right of the saw blade with
your left hand or vice versa is very dangerous.
8. Do not reach behind the vise stop with either
hand from either side of the saw blade, to
remove scraps, or for any other reason while the
blade is spinning. The proximity of the spinning
saw blade to your hand may not be obvious and you
may be seriously injured.
9. Inspect your workpiece before cutting. If the
workpiece is bowed or warped, always make cer-
tain that there is no gap between the clamped
workpiece, vise and vise stop along the line of
the cut. Bent or warped workpieces can twist or shift
and may cause binding on the spinning saw blade
while cutting.
10. Do not use the saw until the table is clear of all
tools, scraps, etc., except for the workpiece.
Small debris or loose pieces of ferrous or other
objects on the table that contact the revolving blade
can be thrown with high speed.
11. Cut only one workpiece at a time. Stacked multi-
ple workpieces cannot be adequately clamped or
braced and may bind on the blade or shift during cut-
ting.
GEB190-1 12. Ensure the power tool is mounted or placed on a
level, firm work surface before use. A level and
firm work surface reduces the risk of the power tool
becoming unstable.
13. Provide adequate support such as blocks, saw
horses, etc. for a workpiece that is wider or
longer than the table top. Workpieces longer or
wider than the metal cutting saw table can tip if not
securely supported. If the cut-off piece or workpiece
tips, it can lift the lower guard or be thrown by the
spinning blade.
14. Do not use another person as a substitute for a
table extension or as additional support. Unsta-
ble support for the workpiece can cause the blade to
bind or the workpiece to shift during the cutting oper-
ation pulling you and the helper into the spinning
blade.
15. The cut-off piece must not be jammed or
pressed by any means against the spinning saw
blade. If confined, i.e. using length stops, the cut-off
piece could get wedged against the blade and
thrown violently.
16. Always use the vise and properly support the
workpiece considering its shape. For example,
Rods and channels have a tendency to roll or shift
while being cut, causing the blade to "bite" and pull
the work with your hand into the blade.
17. Let the blade reach full speed before contacting
the workpiece. This will reduce the risk of the work-
piece being thrown.
18. If the workpiece or blade becomes jammed, turn
the power tool off. Wait for all moving parts to
stop and disconnect the plug from the power
source and/or remove the battery pack. Then
work to free the jammed material. Continued saw-
ing with a jammed workpiece could cause loss of
control or damage to the power tool.
19. After finishing the cut, release the switch, hold
the saw head down and wait for the blade to stop
before removing the cut-off piece. Reaching with
your hand near the coasting blade is dangerous.
20. Hold the handle firmly when making an incom-
plete cut or when releasing the switch before the
saw head is completely in the down position.
The braking action of the saw may cause the saw
head to be suddenly pulled downward, causing a
risk of injury.
21. The outside diameter of the saw blade must be
the specified capacity. Incorrectly sized accesso-
ries cannot be adequately guarded or controlled.
22. The arbour size of saw blade and flanges must
properly fit the spindle of the power tool. Saw
blade and flanges with arbour holes that do not
match the mounting hardware of the power tool will
run out of balance, vibrate excessively and may
cause loss of control.
23. The rated speed of the accessory must be at
least equal to the maximum speed marked on
the power tool.
24. Do not use the metal cutting saw to cut other
than mild steel or stainless steel.
Additional instructions
1. Never stand on the metal cutting saw. Tipping
over or unintentional contact with the cutting means
could cause serious injury.
