Safety Instructions For Mitre Saws - Makita DLS112 Instruction Manual

Safety instructions for mitre saws

1. Mitre saws are intended to cut wood or wood-
like products, they cannot be used with abra-
sive cut-off wheels for cutting ferrous material
such as bars, rods, studs, etc. Abrasive dust
causes moving parts such as the lower guard to
jam. Sparks from abrasive cutting will burn the
lower guard, the kerf insert and other plastic parts.
2. Use clamps to support the workpiece whenever pos-
sible. If supporting the workpiece by hand, you must
always keep your hand at least 100 mm from either side
of the saw blade. Do not use this saw to cut pieces that
are too small to be securely clamped or held by hand. If
your hand is placed too close to the saw blade, there is an
increased risk of injury from blade contact.
3. The workpiece must be stationary and clamped
or held against both the fence and the table. Do
not feed the workpiece into the blade or cut "free-
hand" in any way. Unrestrained or moving work-
pieces could be thrown at high speeds, causing injury.
4. Push the saw through the workpiece. Do not pull
the saw through the workpiece. To make a cut,
raise the saw head and pull it out over the work-
piece without cutting, start the motor, press the
saw head down and push the saw through the
workpiece. Cutting on the pull stroke is likely to cause
the saw blade to climb on top of the workpiece and vio-
lently throw the blade assembly towards the operator.
5. 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.
holding the workpiece to the right of the saw blade
with your left hand or vice versa is very dangerous.
6. Do not reach behind the fence with either hand
closer than 100 mm from either side of the saw
blade, to remove wood scraps, or for any other
reason while the blade is spinning. The proxim-
ity of the spinning saw blade to your hand may not
be obvious and you may be seriously injured.
Inspect your workpiece before cutting. If the
7.
workpiece is bowed or warped, clamp it with
the outside bowed face toward the fence.
Always make certain that there is no gap
between the workpiece, fence and table 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. There should be
no nails or foreign objects in the workpiece.
8. Do not use the saw until the table is clear of all
tools, wood scraps, etc., except for the work-
piece. Small debris or loose pieces of wood or
other objects that contact the revolving blade can
be thrown with high speed.
9. Cut only one workpiece at a time. Stacked multiple
workpieces cannot be adequately clamped or braced
and may bind on the blade or shift during cutting.
10. Ensure the mitre saw is mounted or placed on
a level, firm work surface before use. A level
and firm work surface reduces the risk of the mitre
saw becoming unstable.
11. Plan your work. Every time you change the bevel
or mitre angle setting, make sure the adjustable
fence is set correctly to support the workpiece
and will not interfere with the blade or the guard-
ing system. Without turning the tool "ON" and with
no workpiece on the table, move the saw blade
through a complete simulated cut to assure there will
be no interference or danger of cutting the fence.
12. Provide adequate support such as table exten-
sions, saw horses, etc. for a workpiece that is
wider or longer than the table top. Workpieces
longer or wider than the mitre 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.
13. Do not use another person as a substitute for a
table extension or as additional support. Unstable
support for the workpiece can cause the blade to bind
or the workpiece to shift during the cutting operation
pulling you and the helper into the spinning blade.
14. 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.
15. Always use a clamp or a fixture designed to
properly support round material such as rods
or tubing. Rods have a tendency to roll while
being cut, causing the blade to "bite" and pull the
work with your hand into the blade.
16. Let the blade reach full speed before contact-
ing the workpiece. This will reduce the risk of the
workpiece being thrown.
17. If the workpiece or blade becomes jammed,
turn the mitre saw 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 sawing with a jammed workpiece could
cause loss of control or damage to the mitre saw.
18. 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.
19. 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.
20. Only use the saw blade with the diameter that
is marked on the tool or specified in the man-
ual. Use of an incorrectly sized blade may affect
the proper guarding of the blade or guard opera-
tion which could result in serious personal injury.
