Before Starting Work
Note and follow the following points before each use to ensure safe working with the dry
drilling motor:
• Read through all safety instructions and warnings in this instruction manual.
• Check whether the voltage on the rating plate is identical with the mains voltage.
• Before each use, check the dry drilling motor, connection cable, plug and tight fit of
the core bit.
• Use diamond dry core bits recommended by TYROLIT only.
• Inform and consult the responsible structural engineer, architect or the responsible
site engineer about planned drilling. Cut through reinforcement only with the approval
of a structural engineer.
• Before drilling holes drilling objects, check the rooms concerned for obstructions and
block off this area. Use formwork to secure the drill core against falling.
• Always note the thread dimension of the diamond dry core bit arbor. The thread of the
diamond dry core bits must fit on the thread of the dry drilling motor (G½" internal
thread or 1¼" UNC external thread) without any clearance. Do not use reducers or
adaptors to fit the diamond dry core bits.
• Visually inspect the condition of the diamond dry core bit.
Please note!
Damaged diamond dry core bits may not be used and must be replaced immediately.
• The additional handle must be tightly screwed onto the drill for hand-held drilling.
• Wear protective clothing such as hard hat, hearing protection, face protection or safety
goggles, suitable half-face filter mask, slip-resistant safety footwear and if necessary
an apron.

Fitting/dismantling the extraction tube
(Figure 1)
The extraction tube must be fitted for drilling (Figure 1) to enable a suitable dust ex-
tractor to be connected.
Danger!
Risk of fatal injuries due to electric shock.
► Disconnect the mains plug before carrying out any work on the dry drilling motor.

– Press the spring clip (1) in the direction of the arrow (A) until the legs of the clip
unlatch from the groove of the gearbox extension.
– Remove the extraction tube (2) from the front (B) above the output shaft (3).
