[. . . ] ) Insert the accessory and tighten all 3 bores equally with the chuck key 8. ) When using screwdriver bits 9, a bit holder 10 should always be used. Use only the screwdriver bits that fit the screw head. Do not drill with a bit that is inadequate for the job, because this will damage either your workpiece or the bit itself. [. . . ] TWO-STEP SWITCH (GWS 24-180 JBV) Two rotational speed ranges can be selected with On/Off switch 4. The machine switches from the first to the second rotational speed step after a perceptible pressure point has been exceeded: - Rotational speed step I: 2500 min -1 - Rotational speed step II: 3000 min -1 The On/Off switch can be locked in either of the rotational speed steps by means of locking button 5. STEPLESS SPEED CONTROL (GSB 13 RE) The machine runs with variable speed between 0 and maximum depending on the pressure applied to the On/Off switch 4. Light pressure results in a low rotational speed thus allowing smooth, controlled starts. Do not load the machine so heavily that it comes to a standstill. Using the rotational direction switch 3, the direction of rotation of the machine can be changed (by actuating the On/Off switch 4, the rotational direction switch 3 can be locked). ) Press the rotational direction switch through to the left stop (for drilling, impact drilling, driving screws, etc. Wall tiles and ceramics Begin to drill without impact and activate the impact system after drilling through the enamel surface. By doing this, you prevent the bit to slide or the material to split. Select the right bit By choosing the correct bit for every specific material, and keeping it correctly sharpened, you'll allow your tool to show its best performance. Carbon tipped bits - wood High speed steel bits - soft steel, aluminum, wood, etc. C) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control G) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of these devices can reduce dust-related hazards. Exposure to noise can cause hearing loss. 2) Electrical safety a) Power tool plugs must match the outlet. Do not use any adapter plugs with earthed (grounded) power tools. unmodified plugs and matching outlets will reduce risk of electric shock B) Avoid body contact with earthed or grounded surfaces such as pipes, radiators and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. C) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. Never use the cord for carrying, pulling or unplugging the power tool. [. . . ] Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools operation. If damaged, have the power tool repaired before use. Accidents are caused by poorly maintained power tools. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. [. . . ]
