Remove the battery from the power tool before making any adjustments, changing accessories or
storing the tool. This precaution reduces the risk of the power tool starting accidentally.
▶ Store power tools out of reach of children when not in use. Do not allow persons who are not
familiar with the tool or these instructions to operate it . Power tools are dangerous in the hands of
untrained users.
▶
Maintain power tools properly. Check that moving parts are in correct working order and do not
jam, and check whether any parts are broken or so damaged that correct operation of the power
tool cannot be guaranteed. If any parts are damaged, have these parts repaired before using the
tool. Many accidents are caused by poorly maintained power tools.
▶
Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edges are less likely
to jam and are easier to control.
Using and handling the cordless power tool
▶ Use only the specified batteries in the power tools. Use of any other batteries may present a risk of
injury and fire.
▶
Recharge the batteries only with the chargers specified by the manufacturer. A charger that is
suitable for a certain type of battery may present a risk of fire when used with other types of battery.
▶
When the battery is not in use, keep it away from other metal objects such as paper clips, coins,
keys, nails, screws, or other small metal objects that could cause bridging between the terminals.
A short circuit between the battery terminals may cause burns or a fire.
▶
Liquid may leak from the battery if used incorrectly. Avoid contact with this liquid. Liquid leaking
from the battery may cause skin irritation or burns. If contact accidentally occurs, rinse with water. Seek
medical attention if the liquid comes into contact with the eyes.
2.1.2 Common safety instructions for grinding, polishing and working with wire brushes
▶
This power tool is intended for use as a grinder, wire brush, or cut-off tool. Observe all safety
warnings, instructions, illustrations and specifications provided with this tool. Failure to follow all
instructions listed below can result in electric shock, fire and/or serious injury.
▶
This power tool is not suitable for use as a sander or polisher. Use of the power tool for purposes for
which it is not intended may be hazardous and cause injury.
▶ Do not use accessories not specifically intended and recommended for this power tool by the tool
manufacturer. The fact that an accessory can be attached to your power tool does not necessarily
mean that it can be used in safety.
▶
The rated speed of the accessory must be at least equal to the maximum speed marked on the
power tool. Accessories running faster than their rated speed can disintegrate and fly apart.
▶ The outside diameter and the thickness of the accessory tool must be within the ranges stated for
your power tool. Incorrectly sized accessory tools cannot be adequately guarded or controlled.
▶ Accessory tools with threaded insert must match the thread of the drive spindle. Flange-mounted
accessory tools must have a hole diameter matching the mandrel diameter of the flange. Accessory
tools not correctly fixed to the power tool rotate unevenly, vibrate excessively and can cause control of
the tool to be lost.
▶ Do not use damaged accessory tools . Always check accessory tools before use. Check abrasive
wheels for chipping and cracks. Check grinding discs for cracks and heavy wear and tear, and check
wire brushes for loose or broken wires.
▶ If power tool or accessory is dropped, inspect for damage or install an undamaged accessory.
After inspecting and installing an accessory tool, position yourself and bystanders away from the plane
of the rotating tool and run the power tool at maximum no-load speed for one minute. If an accessory
tool has been damaged it will normally break during this test period.
▶ Wear personal protective equipment. Wear a face shield, eye protection or safety goggles, as
appropriate to the application.
▶ As appropriate, wear a dust mask, ear defenders, protective gloves or a workshop apron to keep
off abrasive particles and particles of workpiece material. Make sure your eyes are protected against
the flying debris created by various machining operations. The dust mask or respirator must be capable
of filtrating particles generated by your operation. Prolonged exposure to high intensity noise may cause
hearing loss.
▶
Keep bystanders a safe distance away from work area. Anyone entering the work area must wear
personal protective equipment. Fragments of workpiece or of a broken accessory may fly away and
cause injury beyond the immediate area of operation.
▶
Hold the power tool by the insulated gripping surfaces only, when carrying out work in which the
accessory tool can come into contact with concealed wiring. If the accessory tool comes into contact
