■ Insert the mains plug only when the machine is switched off. ■ Do not clamp the machine in a vice. ■ Always switch off the machine and allow to come to a stop before placing it down. ■ Do not work with materials containing asbestos. ■ Only use diamond cutting discs with a maximum permissible speed that is at least as high as the no-load speed of the machine. ■ Check the diamond cutting discs before use. The diamond cutting discs must be mounted in exact alignment and be able to rotate freely.
A Changing the Tool ■ Before any work on the machine itself, pull the mains plug. ■ Wear protective gloves. ■ Use only diamond cutting discs suitable for dry cutting of the material with an allowable speed matching at least the no-load speed of the machine. Swiveling out the cutting unit For tool change, the cutting unit must be swiveled out completely. Place the machine on a firm surface. Turn the release lock 1 to the left, using e. g. the spanner end of the two-pin spanner 19.
Dust Extraction Initial Operation The machine must be operated only with dust extraction. The vacuum cleaner must be approved for the extraction of masonry dust. In case of a malfunction of the dust extraction system, stop working, switch the machine off and correct the malfunction of the dust extraction system. The machine can be plugged directly into the receptacle of a Bosch general-purpose vac with remote starting control. The vac starts automatically when the machine is switched on.
Operating Instructions Wear protective goggles, ear protection and a dust protection mask. Wear protective gloves and sturdy shoes. ■ The machine may only be used for dry machining of masonry. Pre-select the cutting depth, as described in the same-named section. Note: To compensate inaccuracies that occur when breaking away the fins, the cutting depth must be set approx. 3 mm deeper than the required slot depth. Place the machine with the chaser rollers 6 on the surface to be worked.
Parallel Guide (Optional extra, GNF 20 CA) Service Indicator 9 (GNF 35 CA) When the carbon brushes are worn out, the machine switches itself off. This is indicated approx. eight hours beforehand by the lighting or blinking of the service indicator 9. The machine must then be sent to customer service for maintenance (for addresses, see Section “Service and Customer Assistance”).
