Operation

Operating Modes

 Before any work on the machine itself, pull the mains

plug.

Pivoting and Retractable Footplate (see figure B–C)

Due to its movability, the adjustable footplate 2 adapts to the

required angular position of the surface.

Depending on the application and the saw blade being used,

the footplate 2 can be moved variably in length direction.

Loosen the screws 13 with Allen key 9 and move the footplate

2 to the requested position. Tighten the screws 13 again and

check if the footplate 2 is tightly seated.

Utility Hook (see figure D)

Your tool is equipped with a utility hook 6 for hanging it, e. g.,

to a ladder, etc. Simply fold out the utility hook 6 to the re-

quired position.

 When the tool is hanging by the utility hook, ensure

that the saw blade is protected against unintended

contact. Danger of injury.

Fold the utility hook 6 back in again when you are ready to

continue working.

Starting Operation

 Observe correct mains voltage! The voltage of the pow-

er source must agree with the voltage specified on the

nameplate of the machine. Power tools marked with

230 V can also be operated with 220 V.

The “Power Light” 10 is lit when the mains plug is inserted,

and allows for illumination of the working range under unfa-

vourable light conditions.

Switching On and Off

To start the machine, first push the lock-off button for the

On/Off switch 7 and then press the On/Off switch 8 and keep

it pressed.

To switch off the machine, release the On/Off switch 8.

Note: For safety reasons, the On/Off switch 8 cannot be

locked; it must remain pressed during the entire operation.

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 8

enables stepless stroke-rate control of the switched-on ma-

chine.

Light pressure on the On/Off switch 8 results in a low stroke

rate. Increasing the pressure also increases the stroke rate.

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.

After longer periods of work at low stroke rate, the machine

can heat up considerably. Allow the machine to cool down by

running it for approx. 3 minutes at maximum stroke rate.

Working Advice

 Before any work on the machine itself, pull the mains

plug.

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 always use the

correct sawblade.

Switch the machine on and guide it toward the workpiece.

Position 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

machine 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 figures E–F)

 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 G)

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.

Maintenance and Service

Maintenance and Cleaning

 Before any work on the machine itself, pull the mains

plug.

 For safe and proper working, always keep the machine

and ventilation slots clean.
