Hazards associated with moving parts
Damage to the workpiece, accessories or even the inserted tool can cause the ejection of parts at high speed. Always use the eye
protection which is impact-resistant. Degree of protection should be selected depending on the work to be done. You should make
sure, that the workpiece is securely clamped. Make sure, that the grinding wheel is securely attached to the grinder. Check that the
maximum speed of the grinding wheel, expressed in revolutions per minute is equal to or greater than rated speed spindle. Make
sure, that guard of the grinding wheel is in its place, that it is in good condition and is correctly mounted. Make sure, that the guard
of grinding wheel is regularly inspected. You should regularly check whether the speed of the grinder is not higher than the rated
speed, which is presented on the grinder. This inspection should be done without mounted grinding wheel and in accordance with
the instructions provided by the manufacturer. Check, whether the applied flanges, which are locking grinding wheels, have been
specified by the manufacturer, and whether they are in good condition, for example devoid of cracks, burrs and whether they are
flat. Check whether the spindle and spindle threads are not damaged or worn. Make sure, that sparks and debris created during
operation do not cause hazards. Unplug the grinder from the pneumatic system before replacing the grinding wheel and repair.
Risks of getting tangled
The risk of getting tangled may cause choking, scalping and/or injury, when loose clothing, jewelry necklaces, hair or gloves are
not kept away from tools or accessories.
The risks associated with the work
Avoid contact with the rotating spindle and mounted grinding wheel to prevent cuts of hands and other parts of the body. Use
of the tool may expose the operator’s hands for threats, such as crushing, impact, cut-off, abrasion and heat. You should dress
appropriate gloves to protect your hands. The operator and maintenance personnel should be physically able to cope with the
quantity, the weight and power of the tool. Grip the tool properly. Be ready to withstand normal or unexpected movements and
always keep both hands ready. Keep balanced position and to ensure the safe foot positioning. Release the start and stop device
in the case of interruption in the power supply. Use only the lubricants, which are recommended by the manufacturer. Use protec-
tive glasses, it recommended to use tight gloves and protective clothing. When you are working over your head, wear protective
helmet. At the moment of stopping movement of the grinding wheel you should hold the grinder in such position, so the grinding
discs would have not contact with any object. You should put the grinder away only after a complete stop to the grinding wheel.
During cutting, treated material should be supported in such a way, that the cut gap will be maintained at a constant or increasing
width, until the end of the cut. In the case of jamming the grinding wheel in the cut gap, turn off the grinder, and then release the
grinding wheel from its jam. Before you start to continue your works, you should check whether the grinding wheel is still correctly
installed and whether it is not damaged. Grinding wheels used for grinding and for abrasive cutting should not be used for grinding
by their side surfaces. (Exception: grinding wheels designed for grinding by their side surface). The grinder should not be operated
above the maximum peripheral speed of grinding wheel. The operator should pay attention that in workplace environment do not
remain bystanders. Use personal protective measures such as: tight gloves, protective apron and helmet. The sparks produced
while working can ignite clothing and cause severe burns. Make sure, that sparks will not go on clothing. Use fire-resistant clothing
and have a bucket of water nearby.
The risks associated with repetitive movements
During the application of the pneumatic tool for work consisting of the repetition of movements, the operator is exposed to experi-
ence discomfort in hands, arms, shoulders, neck or other parts of the body. In the case of use of pneumatic tool, the operator
should take a comfortable posture for correct setting of feet and should avoid postures, that are strange or not providing the
balance. The operator should change posture during the long work, this will help to avoid discomfort and fatigue. If the operator
is experiencing symptoms such as persistent or recurring discomfort, pain, pulsed pain, tingling, numbness, burning or stiffness.
Operator should not ignore them, should tell the employer about it and consult a doctor.
The risks associated with accessories
Disconnect tool from the pneumatic system before changing the inserted tool or accessory. Use accessories and supplies only
in sizes and types, which are recommended by the manufacturer. Do not use accessories of any other type, or other size. Make
sure, that grinding wheel dimensions are compatible with the grinder and, that the grinding wheel matches grinder spindle. Make
sure, that the type and size of the thread of grinding wheel exactly matches the type and size of the spindle thread. Check the
grinding wheel before its use. Do not use grinding wheels, that (presumably) have been dropped or are cracked, have broken off
fragments, are slightly broken or damaged in any other way. Before use, you should check whether the grinding wheel is properly
mounted and tightened. You should start the grinder without any load for 1 minute in a safe position. Stop it immediately if you
notice excessive vibration or other defects, and then to examine the cause of this defect. Prevent situations where spindle tip
touches the bowl bottom, cones or pins with threaded holes, designed for mounting on machine spindles, by examining their sizes
and other data. When with the grinding wheel there have been supplied reducing bushings or adapters, the user should make
sure, that the adapter or bushing will not have contact with front part of the mounting flange, and, that clamping forces will be suf-
ficient to prevent slipping of the grinding wheel during its revolutions. Where the mounting flanges have been delivered in several
types or sizes, you should always match the right flange (flanges) to the grinding wheel. Avoid direct contact with the inserted tool
during or immediately after work, because it may be sharp or hot. Keep and move the grinding wheel with care in accordance with
manufacturer’s instructions.
