otherwise kickback may occur. Investigate and take
corrective action to eliminate the cause of saw blade
binding.
Do not restart the cutting operation in the workpiece.
u
Let the saw blade reach full speed and carefully re-
enter the cut. The saw blade may bind, walk up or kick-
back if the power tool is restarted in the workpiece.
Support any oversized workpiece to minimize the risk
u
of saw blade pinching and kickback. Large workpieces
tend to sag under their own weight. Supports must be
placed under the workpiece near the line of cut and near
the edge of the workpiece on both sides of the saw blade.
Use clamps to support the workpiece whenever pos-
u
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.
The workpiece must be stationary and clamped or
u
held against both the fence and the table. Do not feed
the workpiece into the blade or cut "freehand" in any
way. Unrestrained or moving workpieces could be thrown
at high speeds, causing injury.
Push the saw through the workpiece. Do not pull the
u
saw through the workpiece. To make a cut, raise the
saw head and pull it out over the workpiece 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 violently throw the blade assembly
towards the operator.
Never cross your hand over the intended line of cut-
u
ting 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.
Do not reach behind the fence when the saw blade is
u
rotating. Never fail to maintain a safe distance of 100
mm between hand and rotating saw blade (applies to
both sides of the saw blade). It might not be possible to
tell how close the rotating saw blade is to your hand, and
you may be severely injured.
Inspect your workpiece before cutting. If the work-
u
piece 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 work-
pieces 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.
Do not use the power tool until the table is free of
u
tools; the workpiece must be the only thing on the
table. Small pieces of scrap or other objects that come
into contact with the rotating blade can be hurled away at
high speed.
Bosch Power Tools
Cut only one workpiece at a time. Stacked multiple
u
workpieces cannot be adequately clamped or braced and
may bind on the blade or shift during cutting.
Ensure the power tool is mounted or placed on a level,
u
firm work surface before use. A level and firm work sur-
face reduces the risk of the power tool becoming un-
stable.
Plan your work. Every time you change the bevel or
u
mitre angle setting, make sure the adjustable fence is
set correctly to support the workpiece and will not in-
terfere with the blade or the guarding 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.
Provide adequate support such as table extensions,
u
saw horses, etc. for a workpiece that is wider or
longer than the table top. Workpieces longer or wider
than the power tool table can tip if not securely suppor-
ted. If the cut-off piece or workpiece tips, it can lift the
lower guard or be thrown by the spinning blade.
Do not use another person as a substitute for a table
u
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.
The cut-off piece must not be jammed or pressed by
u
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.
Always use a clamp or a fixture designed to properly
u
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.
Let the blade reach full speed before contacting the
u
workpiece. This will reduce the risk of the workpiece be-
ing thrown.
If the workpiece or blade becomes jammed, turn the
u
power tool off. Wait for all moving parts to stop and
disconnect the plug from the power source and/or re-
move the battery pack. Then work to free the jammed
material. Continued cutting with a jammed workpiece
could cause loss of control or damage to the power tool.
After finishing the cut, release the switch, hold the
u
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.
Hold the handle firmly when making an incomplete cut
u
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.
Never remove cuttings etc. from the cutting area
u
while the power tool is running. Always guide the tool
arm back to the neutral position first and then switch the
power tool off.
