▶
Use personal protective equipment. Always wear eye protection. Protective equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce
personal injuries.
▶
Prevent unintentional starting. Ensure the switch is in the off‐position before connecting to power
source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on
the switch or energising power tools that have the switch on invites accidents.
▶
Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may result in personal injury.
▶
Do not overreach. Keep proper footing and balance at all times. This enables better control of the
power tool in unexpected situations.
▶
Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
▶
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.
Power tool use and care
▶
Do not force the power tool. Use the correct power tool for your application. The correct power tool will
do the job better and safer at the rate for which it was designed.
▶
Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must be repaired.
▶
Disconnect the plug from the power source and/or the battery pack from the power tool before
making any adjustments, changing accessories, or storing power tools. Such preventive safety
measures reduce the risk of starting the power tool accidentally.
▶
Store idle power tools out of the reach of children and do not allow persons unfamiliar with the
power tool or these instructions to operate the power tool. Power tools are dangerous in the hands
of untrained users.
▶
Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and
any other condition that may affect the power tool’s operation. If damaged, have the power tool
repaired before use. Many accidents are caused by poorly maintained power tools.
▶
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
▶
Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking
into account the working conditions and the work to be performed. Use of the power tool for
operations different from those intended could result in a hazardous situation.
Service
▶
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.
2.2 General safety instructions applicable to grinding and polishing
▶
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 the power tool does not necessarily mean
that it can be used safely.
▶
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 a 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 secured to the power tool rotate unevenly, vibrate excessively and can cause loss of
control of the tool.
▶
Do not use damaged accessory tools. Check the condition of the accessory tool before each
use, i.e. check abrasive discs for chips and cracks, and check backing pads for cracks, tears or
excessive wear. If the power tool or accessory tool is dropped, inspect it for damage or use an
undamaged accessory tool. 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 usually 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 protection, protective gloves
and a workshop apron to protect you from flying abrasive particles and fragments of the material
you are working on. Make sure your eyes are protected against the flying debris created by various
