Stroke speed selector switch 6 – central position:
The safety lock is activated.
The On/Off switch 7 is blocked and the machine
is secured against being switched on uninten-
tionally.
Stroke speed selector switch 6 – left:
1. Gear, low stroke speed.
The low stroke speed is suitable for sawing hard
materials such as steel, non-ferrous metal, hard
plastics or for precision cuts in wood and plunge
cutting.
The low stroke speed enables sawing with less
vibrations.
Stroke speed selector switch 6 – right:
2. Gear, high stroke speed.
The high stroke speed is suitable for sawing soft
materials.
The high stroke speed enables quicker opera-
tional progress, e. g., for coarse cuts in wood.
Switching On and Off
To start the machine, press the On/Off switch 7 and keep it
pressed.
To switch off the machine, release the On/Off switch 7.
To save energy, only switch the power tool on when using it.
Controlling the Stroke Rate
Increasing or reducing the pressure on the On/Off switch 7
enables stepless stroke-rate control of the switched-on ma-
chine.
The required stroke rate is dependent on the material and the
working conditions and can be determined by a practical trial.
Reducing the stroke rate is recommended when the saw
blade engages in the material as well as when sawing plastic
and aluminium.
Protection Against Deep Discharging
The Lithium-Ion battery is protected against deep discharging
by the "Electronic Cell Protection (ECP)". When the battery is
empty, the machine is switched off by means of a protective
circuit: The inserted tool no longer rotates.

Working Advice

 Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
Pivoting Footplate (see figure D)
Due to its movability, the adjustable footplate 2 adapts to the
required angular position of the surface.

Tips
 When sawing light building materials, observe the stat-
utory provisions and the recommendations of the ma-
terial suppliers.
Check wood, press boards, building materials, etc. for foreign
objects such as nails, screws or similar, and remove them, if
required.
Switch the machine on and guide it toward the workpiece. Po-
sition the footplate 2 onto the surface of the work and saw
through the material applying uniform contact pressure and
feed. After completing the working procedure, switch the ma-
chine off.
If the saw blade should jam, switch the machine off immedi-
ately. Widen the gap somewhat with a suitable tool and pull
out the machine.
Plunge Cutting (see figure E)
 The plunge cutting procedure is only suitable for treat-
ing soft materials such as wood, plaster board or simi-
lar! Do not work metal materials with the plunge cut-
ting procedure!
Use only short saw blades for plunge cutting.
Place the machine with the edge of the footplate 2 onto the
workpiece and switch on. For power tools with stroke speed
control, set the maximum stroke speed. Press the power tool
firmly against the workpiece and allow the saw blade to slowly
plunge into the workpiece.
As soon as the footplate 2 fully lays on the surface of the work-
piece, continue sawing alongside the desired cutting line.
For certain work, the saw blade 1 can also be inserted turned
through by 180° and the sabre saw can be guided accordingly
in a reversed manner.
Flush Cuts (see figure F)
Using elastic bimetal saw blades, items still attached to a wall
(e. g. projecting building elements such as water pipes, etc.)
can be sawn off flush at the wall.
 Pay attention that the saw blade always extends be-
yond the diameter of the material being worked. There
is danger of kickback.
Position the saw blade directly against the wall and apply
some lateral pressure via the tool until the footplate faces
against the wall. Switch the power tool on and saw through
the workpiece, applying constant lateral pressure.
Coolant/Lubricant
When sawing metal, coolant/lubricant should be applied
alongside cutting line because of the material heating up.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Store the battery only within a temperature range between
0 °C and 50 °C. As an example, do not leave the battery in the
car in summer.
Occasionally clean the venting slots of the battery using a soft,
clean and dry brush.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
Observe the notes for disposal.
