Further Safety Instructions For All Saws - Hilti SCM 18-A Manual De Instrucciones

Keep cutting tools sharp and clean. Properly main-
f)
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc.
in accordance with these instructions taking into
account the working conditions and the work to
en
be performed. Use of the power tool for opera-
tions different from those intended could result in a
hazardous situation.
5.1.5 Battery tool use and care
a) Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of fire when used
with another battery pack.
b) Use power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire.
c) When battery pack is not in use, keep it away
from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects,
that can make a connection from one terminal to
another. Shorting the battery terminals together may
cause burns or a fire.
d) Under abusive conditions, liquid may be ejected
from the battery, avoid contact. If contact acci-
dentally occurs, flush with water. If liquid contacts
eyes, additionally seek medical help. Liquid ejected
from the battery may cause irritation or burns.
5.1.6 Service
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is
maintained.

5.2.1 Cutting procedures
a)
DANGER
Keep hands away from cutting area and the blade.
Keep your second hand on auxiliary handle, or
motor housing. If both hands are holding the saw,
they cannot be cut by the blade.
b) Do not reach underneath the workpiece. The guard
cannot protect you from the blade below the work-
piece.
c) Adjust the cutting depth to the thickness of the
workpiece. Less than a full tooth of the blade teeth
should be visible below the workpiece.
d) Never hold piece being cut in your hands or across
your leg. Secure the workpiece to a stable plat-
form. It is important to support the work properly to
minimize body exposure, blade binding, or loss of
control.
e) Hold power tool by insulated gripping surfaces,
when performing an operation where the cutting
tool may contact hidden wiring. Contact with a
"live" wire will also make exposed metal parts of the
power tool "live" and shock the operator.

When ripping always use a rip fence or straight
f)
edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
g) Always use blades with correct size and shape
(diamond versus round) of arbour holes. Blades
that do not match the mounting hardware of the saw
will run eccentrically, causing loss of control.
h) Never use damaged or incorrect blade washers
or bolt. The blade washers and bolt were specially
designed for your saw, for optimum performance and
safety of operation.

Causes and Operator Prevention of Kickback:
kickback is a sudden reaction to a pinched, bound or
misaligned saw blade, causing an uncontrolled saw to lift
up and out of the workpiece toward the operator;
when the blade is pinched or bound tightly by the kerf
closing down, the blade stalls and the motor reaction
drives the unit rapidly back toward the operator;
if the blade becomes twisted or misaligned in the cut, the
teeth at the back edge of the blade can dig into the top
surface of the wood causing the blade to climb out of the
kerf and jump back toward the operator.
Kickback is the result of saw misuse and/or incorrect
operating procedures or conditions and can be avoided
by taking proper precautions as given below.
a) Maintain a firm grip with both hands on the saw
and position your arms to resist kickback forces.
Position your body to either side of the blade, but
not in line with the blade. Kickback could cause the
saw to jump backwards, but kickback forces can be
controlled by the operator, if proper precautions are
taken.
b) When blade is binding, or when interrupting a
cut for any reason, release the trigger and hold
the saw motionless in the material until the blade
comes to a complete stop. Never attempt to re-
move the saw from the work or pull the saw back-
ward while the blade is in motion or kickback
may occur. Investigate and take corrective actions
to eliminate the cause of blade binding.
c) When restarting a saw in the workpiece, centre
the saw blade in the kerf and check that saw
teeth are not engaged into the material. If saw
blade is binding, it may walk up or kickback from the
workpiece as the saw is restarted.
d) Support large panels to minimise the risk of blade
pinching and kickback. Large panels tend to sag
under their own weight. Supports must be placed
under the panel on both sides, near the line of cut
and near the edge of the panel.
e) Do not use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
f) Blade depth and bevel adjusting locking levers
must be tight and secure before making cut. If
blade adjustment shifts while cutting, it may cause
binding and kickback.
