Additional safety guidelines for angle grinders
 Do not use any attachments that are not specifically designated or recommended by
the manufacturer for this device. Just because you can attach an attachment to your
device does not guarantee that it can be safely used.
 The permissible rotational speed for the insertion tool must be at least as high as the
device's specified highest rotational speed. Attachments that rotate faster than the
permissible speed can shatter, creating flying shards.
 The outer diameter and thickness of the insertion tool must be in accordance with the
dimensions of your device. Insertion tools with the wrong dimensions cannot be
adequately shielded or controlled.
 Grinding discs, flanges, grinding plates and other attachments must fit the grinding
spindle of your device exactly. Insertion tools that do not fit exactly to the device's grinding
spindle rotate irregularly, vibrate very strongly, and can lead to a loss of control.
 Do not use damaged insertion tools. Each time before you use an insertion tool such
as a grinding or cutting disc, check for chipping, cracks, signs of wear, or heavy
abrasion. If the device or insertion tool should fall, check if it is damaged or use an
undamaged insertion tool. Once you have checked the insertion tool and inserted it,
make sure that you and everyone in the vicinity stay outside of the plane of the
rotating insertion tool and let the device run for one minute at the highest rotation
speed. Damaged insertion tools will usually break during this test period.
 Wear personal safety equipment. According to the usage, use full facial protection,
eye protection or safety glasses. If required, wear a dust mask, ear protection,
protective gloves or a specialized apron to protect against shards and other particles.
Your eyes should be protected against flying shards that result from various forms of usage.
Dust or respirator masks must be able to filter out the dust that results from usage of the
device. If you are exposed to loud noise for long periods of time, you may suffer from
hearing loss.
 Make sure that others stay at a safe distance to your work area. Every person who
enters the work area must wear personal safety equipment. Broken pieces of the work
piece or broken insertion tools can fly away and lead to injuries even outside of the work
area.
 Hold the device only on the isolated handle area when you are doing work in which
the insertion tool may come into contact with concealed power lines or the device's
power cord. Contact with a live power line can electrically charge the device's metallic parts
and lead to electric shock.
 Keep the power cord away from rotating insertion tools. If you lose control of the device,
the power cord may be cut or caught and your hand or arm may come into contact with the
rotating insertion tool.
 Never put the device down before the insertion tool has completely stopped moving.
The rotating insertion tool may come into contact with the material holder, which can lead to
a loss of control.
 Make sure the machine is not on while you are carrying it. If your clothing accidentally
comes into contact with the rotating insertion tool, it may be caught and pull the insertion tool
toward your body.
 Clean the device's ventilation slots regularly. The motor fan pulls dust into the housing,
and a heavy build-up of metal dust can lead to electrical dangers.
 Do not use the device in the vicinity of flammable materials. Sparks may ignite such
materials.
