English | 21 General Power Tool Safety Warnings en WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool. 1) Work area safety a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
22 | English g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards. 5) Service a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained. 4) Power tool use and care a) Do not force the power tool. Use the correct power tool for your application.
English | 23 f Do not use a damaged accessory. Before each use, inspect the accessory such as abrasive wheels for chips and cracks, backing pads for cracks, tears or excess wear, wire brushes for loose or cracked wires. If power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute.
24 | English f Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken. f Never place your hand near the rotating accessory. The accessory may kickback over your hand.
English | 25 f Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback. Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel. f Use extra caution when making a “pocket cut” into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.
26 | English Functional Description Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

28 | English Noise/Vibration Information Assembly Measured values determined according to EN 60745. Mounting the Protective Devices Typically the A-weighted noise levels of the product are: Sound pressure level 89 dB(A); Sound power level 100 dB(A). Uncertainty K =3 dB. Wear hearing protection! Vibration total values (triax vector sum) determined according to EN 60745: Surface grinding: Vibration emission value ah =7.1 m/s2, Uncertainty K=1.5 m/s2, Disk sanding: Vibration emission value ah =3.
English | 29 Hand Guard f For operations with the rubber sanding plate 15 or with the cup brush/wheel brush/flap disc, always mount the hand guard 14. The hand guard 14 is fastened with the auxiliary handle 4. Mounting the Grinding Tools f Before any work on the machine itself, pull the mains plug. f Grinding and cutting discs become very hot while working; do not touch until they have cooled. Clean the grinder spindle 5 and all parts to be mounted.
30 | English 21 Lock the grinder spindle with the spindle lock button 1. To tighten the quick-clamping nut, firmly turn the grinding disc in clockwise direction. Approved Grinding Tools All grinding tools mentioned in these operating instructions can be used. The permissible speed [rpm] or the circumferential speed [m/s] of the grinding tools used must at least match the values given in the table. Therefore, observe the permissible rotational/circumferential speed on the label of the grinding tool.
English | 31 Rotating the Machine Head Operation f Before any work on the machine itself, pull the mains plug. Starting Operation The machine head can be rotated with respect to the machine housing in 90° steps. In this manner, the On/Off switch can be brought into a more convenient position for special working situations, e.g. for left-handed persons. Completely unscrew the four screws. Rotate the machine head carefully, without removing it from the housing, to the new position.
32 | English Speed preselection (GWS 6-100 E/GWS 6-115 E/GWS 6-125 E/GWS 850 CE) The required speed can be preselected with the thumbwheel 3 (also while running). The data in the following table are recommended values.
English | 33 Switch on the machine and place the front part of the cutting guide on the workpiece. Slide the machine with moderate feed, adapted to the material to be worked. For cutting expecially hard material, e. g., concrete with high pebble content, the diamond cutting disc can overheat and become damaged as a result. This is clearly indicated by circular sparking, rotating with the diamond cutting disc.
