Overload Protection - Makita DSC250 Betriebsanleitung

CAUTION:
Hold the tool firmly so that it does
not shake when cutting. Cutting with the tool
shaking will shorten the life of the Tipped Saw and
damage the blades.
CAUTION:
Position the tool so it is at 90
degrees to rebar to be cut. If the tool is not at 90
degrees to the rebar, it can cause shaking and
overload the tool.
CAUTION:
Do not start cutting immediately
after the motor is switched on. Allow the Tipped
Saw to reach full speed before beginning to cut.
CAUTION:
Do not remove the battery when
the motor is switched on. Doing so can cause
damage to the motor's electronics.
6. After finishing the cut, push down on the rear end
of the Switch which will cause the Switch to move to the
"O" position and turn off the motor.
CAUTION:
This tool is designed to cut rebar.
Please contact the manufacturer or your local
dealer if you want to cut other materials. Cutting
other materials will damage the Tipped Saw
blades.
Caution when cutting
1. Ensure that the Tipped Saw blade is well away
from the material to be cut before switching on.
2. Slow down the forward (cutting) movement of the
tool when approaching the end of the cut. This is espe-
cially important when the piece to be cut is less than 50
mm in length. The piece cut off can strike the Tipped
Saw blades, damaging them and cause serious injury.
3. When the Tipped Saw blades become blunt or
chipped. replace the blade. Continuing to use it in this
condition will overload the tool.
4.
If the material moves or shakes, when being cut,
stop the operation and properly secure the material.
5. Do not hold by hand the material to be cut. Doing
so may result in personal injury.
6. Do not cut rebar that in size or hardness exceeds
the cutting capacity of the tool.
Replace the Tipped Saw when any
of the below occurs
1. Warning Lamp (red) blinks frequently even though
the battery is fully charged.
2. The Tipped Saw blades are chipped or worn.
3. The cutting speed is very slow.
4. The surface of the cut piece is discolored by heat.
NOTE: Tipped Saw blades cannot be resharpened.

flammable material but very hot debris, such as
that produced when cutting with a worn Tipped
Saw blade, can melt the material. Be aware of this
possibility when using the Dust Bag.
