Additional Safety Rules For Tool - Makita 4131 Betriebsanleitung

20. Check damaged parts
Before further use of the tool, a guard or other part
that is damaged should be carefully checked to
determine that it will operate properly and perform
its intended function. Check for alignment of moving
parts, binding of moving parts, breakage of parts,
mounting, and any other conditions that may affect
its operation. A guard or other part that is damaged
should be properly repaired or replaced by an autho-
rized service center unless otherwise indicated else-
where in this instruction manual. Have defective
switches replaced by and authorized service center.
Do not use tool if switch does not turn it on and off.
21. Warning
The use of any other accessory or attachment other
than recommended in this operating instruction or
the catalog may present a risk of personal injury.
22. Have your tool repaired by an expert
This electric appliance is in accordance with the rel-
evant safety rules. Repairing of electric appliances
may be carried out only by experts otherwise it may
cause considerable danger for the user.

ADDITIONAL SAFETY RULES FOR TOOL

DANGER:
1. Keep hands away from cutting area and the
blade. Keep your second hand on auxiliary han-
dle, or motor housing. If both hands are holding
the tool, they cannot be cut by 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 piece being cut in your hands or
across your leg. Secure the workpiece to a sta-
ble platform. It is important to support the work
properly to minimize body exposure, blade binding,
or loss of control.
A typical illustration of proper hand support,
workpiece support, and supply cord routing
(if applicable).
5. Hold power tool by insulated gripping surfaces
when performing an operation where the cutting
tool may contact hidden wiring or its own cord.
Contact with a "live" wire will also make exposed
metal parts of the power tool "live" and shock the
operator.

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 tool
will run eccentrically, causing loss of control.
8. Never use damaged or incorrect blade washers
or bolt. The blade washers and bolt were specially
designed for your tool, for optimum performance and
safety of operation.
9. Causes and operator prevention of kickback;
• Kickback is a sudden reaction to a pinched,
bound or misaligned saw blade, causing an
uncontrolled tool to lift up and out of the work-
piece 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 workpiece
causing the blade to climb out of the kerf and
jump back toward the operator.
ENB082-3
Kickback is the result of tool 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
tool 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 tool to jump backwards, but kick-
back 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 tool motionless in the material until
the blade comes to a complete stop. Never
attempt to remove the tool from the work or
pull the tool backward 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 tool in the workpiece, cen-
tre 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 tool 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.
To avoid kickback, do support board or panel
near the cut.
