Makita DHS782 Instruction Manual page 11

NOTE: The declared vibration total value(s) has been
measured in accordance with a standard test method
and may be used for comparing one tool with another.
NOTE: The declared vibration total value(s) may also
be used in a preliminary assessment of exposure.
WARNING:
The vibration emission during
actual use of the power tool can differ from the
declared value(s) depending on the ways in which
the tool is used especially what kind of workpiece
is processed.
WARNING:
Be sure to identify safety mea-
sures to protect the operator that are based on an
estimation of exposure in the actual conditions of
use (taking account of all parts of the operating
cycle such as the times when the tool is switched
off and when it is running idle in addition to the
trigger time).

SAFETY WARNINGS
General power tool safety warnings
WARNING:
Read all safety warnings, instruc-
tions, illustrations and specifications provided
with this power tool. Failure to follow all instructions
listed below may result in electric shock, fire and/or
serious injury.
Save all warnings and instruc-
tions for future reference.
The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.

Cutting procedures
1. 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.
Do not reach underneath the workpiece. The
2.
guard cannot protect you from the blade below the
workpiece.
3. 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.
4. Never hold the workpiece in your hands or
across your leg while cutting. Secure the
workpiece to a stable platform. It is important to
support the work properly to minimise body expo-
sure, blade binding, or loss of control.

5. Hold the 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 could give the operator an electric shock.
6. When ripping, always use a rip fence or
straight edge guide. This improves the accuracy
of cut and reduces the chance of blade binding.
Always use blades with correct size and shape
7.
(diamond versus round) of arbour holes. Blades
that do not match the mounting hardware of the
saw will run off-centre, causing loss of control.
8. Never use damaged or incorrect blade wash-
ers or bolt. The blade washers and bolt were
specially designed for your saw, for optimum
performance and safety of operation.
Kickback causes and related warnings
— kickback is a sudden reaction to a pinched, jammed 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 jammed tightly by the
kerf closing down, the blade stalls and the motor reac-
tion 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.
Maintain a firm grip with both hands on the saw
1.
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 con-
trolled by the operator, if proper precautions are taken.
2. 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 remove the saw from the work or pull the
saw backward while the blade is in motion or
kickback may occur. Investigate and take correc-
tive actions to eliminate the cause of blade binding.
3. When restarting a saw in the workpiece, centre
the saw blade in the kerf so that the saw teeth
are not engaged into the material. If a saw blade
binds, it may walk up or kickback from the work-
piece as the saw is restarted.
4. 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.

► Fig.3
Do not use dull or damaged blades. Unsharpened
5.
or improperly set blades produce narrow kerf caus-
ing excessive friction, blade binding and kickback.
Blade depth and bevel adjusting locking levers
6.
must be tight and secure before making the
cut. If blade adjustment shifts while cutting, it may
cause binding and kickback.
