Ec Declaration Of Conformity; General Power Tool Safety Warnings - Makita DHS900 Betriebsanleitung

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 measures
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 run-
ning idle in addition to the trigger time).

EC Declaration of Conformity

For European countries only
The EC declaration of conformity is included as Annex A
to this instruction manual.
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.
2. Do not reach underneath the workpiece. The 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.
7. 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
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 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.
1. 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.
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 corrective actions to eliminate the cause of
blade binding.
When restarting a saw in the workpiece, centre
3.
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.

5. Do not use dull or damaged blades.
Unsharpened or improperly set blades produce
narrow kerf causing 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.
Use extra caution when sawing into existing
7.
walls or other blind areas. The protruding blade
may cut objects that can cause kickback.
