the tool.
6.2 Use of a generator or transformer
This tool can be powered by a generator or by way of a
transformer connected to the construction site electric
supply when the following conditions and specifications
are fulfilled:
– Alternating current, power output at least 2600 W.
– The operating voltage must remain within +5% and –
15% of the rated voltage at all times.
7. Operation
Use clamps or a vice to secure the work-
piece.
The work piece is thus held more securely
than by hand and both hands remain free to operate the
tool.

– The equipment must be fitted with an automatic volt-
age regulator with starting compensation.
Never operate other tools or appliances from the
generator or transformer at the same time. Switching
other tools or appliances off and on can result in sudden
overvoltage or undervoltage which may cause damage
to the tool.
6.3 Fitting and removing the belt hook (SD 2500)

Use the screw to attach the belt hook.
6.3.2 Removing the belt hook
Detach the belt hook from the tool by removing the
screw.
– Pushbutton moved to the left (as seen with tool in
working position) = reverse rotation.
7.2 Switching on / off
1. Plug the supply cord into the electric socket.
2. Press the control switch slowly. The speed of the tool
can thus be varied between 0 and maximum speed.
7.3 Lockbutton for sustained operation

running constantly) without need to maintain pressure
on the control switch.
7.3.1 Switching on in sustained operating mode
1. Press the control switch as far as it will go.
2. Press the lockbutton while maintaining pressure
on the control switch and then release the control
switch.
7.3.2 Switching off when running in sustained mode
1. Press the control switch. The lockbutton returns to
its original position.
