Additional Safety Rules - Makita JR3020 Betriebsanleitung

19. Stay alert
Watch what you are doing. Use common sense.
Do not operate tool when you are tired.
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 per-
form 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 authorized service center unless
otherwise indicated elsewhere 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
relevant safety rules. Repairing of electric appli-
ances may be carried out only by experts other-
wise it may cause considerable danger for the user.

ADDITIONAL SAFETY RULES

1. Wear a hard hat (safety helmet), safety
glasses and/or face shield. It is also highly
recommended that you wear a dust mask, ear
protectors and thickly padded gloves.
2. Check the blade carefully for cracks or dam-
age before operation. Replace cracked or
damaged blade immediately.
3. Do not attempt to cut workpieces larger than
specified in this manual (especially hollow
pipe). The blade might snap and cause an
injury. (Fig. 1)
4. Hold the tool firmly.
5. Be sure no one is below when using the tool
in high locations.
6. Do not point the tool at anyone in the immedi-
ate vicinity.
7. When making a "blind" cut (you can't see
behind what is being cut), be sure that hidden
electrical wiring or water pipes are not in the
path of the cut. If wires are present, they must
be disconnected at their power source by a
qualified person or avoided to prevent the
possibility of lethal shock or fire. Always hold
the tool ONLY by the insulated gripping sur-
faces to prevent any electric shock if you
accidentally cut through a "live" wire. Water
pipes in "blind" areas must be drained and
capped before cutting.

8. Be careful not to hit the end of the blade
against something during operation. Damage
to the tool or dangerous blade breakage may
occur. (Fig. 2)
9. Watch out for cut-off portions of the work-
piece being cut. They may fall and injure you
or someone near you.
10. When cutting metals, be cautious of hot fly-
ing chips.
11. Do not touch the blade or the workpiece
immediately after operation; they may be
extremely hot and could burn your skin.
12. If you withdraw the blade from the workpiece
during operation, strong reaction will be pro-
duced, causing the blade to snap or causing
you to lose your grip and control of the tool.
Always switch off the tool and wait until the
blade has come to a complete stop before
withdrawing the blade from the workpiece.
SAVE THESE INSTRUCTIONS.
OPERATING INSTRUCTIONS
Important:
Always be sure that the tool is switched off and
unplugged before installing or removing the saw
blade, or adjusting the shoe.
Installing or removing saw blade (Fig. 3 & 4)
To install the blade, loosen the bolt with the hex
wrench 4. Insert the blade between the leaf spring
and the slider so that the pin on the slider fits into the
hole in the blade shank. Tighten the bolt securely
while making sure that the blade cannot be extracted
even though you try to pull it out.
CAUTION:
If you tighten the bolt without the pin on the slider fit-
ting properly in the hole in the blade shank, the pin or
the blade shank will be damaged. This may cause
the blade to be ejected unexpectedly during opera-
tion. This can be extremely dangerous.
To remove the blade, follow the installation proce-
dures in reverse.
Adjusting the shoe (Fig. 5)
When the blade loses its cutting efficiency in one
place along its cutting edge, reposition the shoe to
utilize a sharp, unused portion of its cutting edge.
This will help to lengthen the life of the blade. To
reposition the shoe, loosen the lever and slide the
shoe forward or back to the desired position. Then
tighten the lever to firmly secure the shoe.
