SWITCH
The switch ✪✌ on both of these tools are fitted with a locking device ✫✌ allowing the tool to be operated for long periods of time without interruptions. Fig.2.
Before inserting the plug into the socket, check that the switch is in the unlocked position. When the tool is not to be used for long periods remember to leave the switch device in the unlocked position.
SPEED CHANGE
Both of the drills in this range are equipped with a two speed mechanical gear change.
The two different speeds are engaged by rotating the control knob located on the left hand side of the machine head. The markings I and II on the knob indicate respectively the slow and fast speeds.
THIS OPERATION SHOULD BE PERFORMED WHEN THE MACHINE IS STOPPED.
An arrow on the machine body indicates the engaged speed.

–Current limiter: a safety device which reduces the electric power supply of the tool, when there is an overload of 1600W.
PERCUSSION DRILLING SYSTEM
Both of these drills can pass from normal drilling to percussion drilling, simply by moving the lever fitted at the head of the drill. It is possible to turn the percussion system on and off, even whilst the machine is running and without the risk of causing damage to the mechanism.
Drilling position: rotate the lever to the right, ie. towards the drill bit symbol.
Percussion drilling position: rotate the lever to the left, ie. towards the hammer symbol.
Only use the percussion in the forward rotation.
CHANGING THE DIRECTION OF ROTATION
Both drills are equipped with a direction inverting device ✮✌ in order to be able to rotate the machine chuck either to the right or to the left. THIS OPERATION SHOULD
BE PERFORMED WHEN THE MACHINE IS STOPPED.
