comfortable posture while maintaining secure footing 

and avoiding awkward or off-balanced postures. The 

operator should change posture during extended 

tasks; this can help avoid discomfort and fatigue.

 

If the operator experiences symptoms, such as 

persistent or recurring discomfort, pain, throbbing, 

aching, tingling, numbness, burning sensations or 

stiffness, these warning signs should not be ignored. 

The operator should tell the employer and consult a 

qualified health professional.

ACCESSORY HAZARDS

 

Disconnect the grinder from the energy supply before 

fitting or changing the inserted tool or accessory.

 

Only use sizes and types of accessories and 

consumables that are recommended by the grinder 

manufacturer; do not use other types or sizes of 

accessories or consumables.

 

Ensure that the dimensions of the abrasive product 

are compatible with the grinder and that the abrasive 

product fits the spindle.

 

Ensure that the thread type and size of the abrasive 

product exactly match the thread type and size of the 

spindle.

 

Inspect the abrasive product before use. Do not use 

abrasive products which can (possibly) have been 

dropped or which are chipped, cracked or otherwise 

defective.

 

Ensure that the abrasive product is correctly mounted 

and tightened before use and run the grinder at no-

load speed for at least 1 min in a safe position; stop 

immediately if considerable vibration or other defects 

are detected and determine the cause of these defects.

 

Prevent the spindle end from touching the bottom of 

the hole of cups, cones or plugs with threaded holes, 

intended to be mounted on machine spindles, by 

checking their dimensions and other relevant data.

 

Where abrasive products are supplied or used with 

reducing adaptors or bushings, the user shall ensure 

that the adaptor or bushing does not contact the face 

of the flange and that the clamping force provides 

sufficient rotational driving action to prevent the 

abrasive product from slipping.

 

In cases where flanges are supplied for several types 

or sizes of abrasive, always fit the correct flange(s) for 

the abrasive being used.

 

Avoid direct contact with the inserted tool during and 

after use as it can be hot or sharp.

 

Store and handle the abrasive product with care in 

accordance with manufacturer’s instructions.

WORKPLACE HAZARDS

 

Slips, trips and falls are major causes of workplace 

injury. Be aware of slippery surfaces caused by use of 

the tool and also of trip hazards caused by the air line 

or hydraulic hose.

 

Proceed with care in unfamiliar surroundings. There 

can be hidden hazards, such as electricity or other 

utility lines.

 

This grinder is not intended for use in potentially 

explosive atmospheres and is not insulated from 

coming into contact with electric power.

 

Ensure that there are no electrical cables, gas pipes, 

etc., which can cause a hazard if damaged by use of 

the tool.

DUST AND FUME HAZARDS

 

Dusts and fumes generated while using grinders can 

cause ill health (for example cancer, birth defects, 

asthma and/or dermatitis); risk assessment of these 

hazards and implementation of appropriate controls 

for these hazards are essential.

 

Risk assessment should include dust created by the 

use of the tool and the potential for disturbing existing 

dust.

 

Operate and maintain the grinder as recommended in 

these instructions, to minimize dust or fume emissions.

 

Direct the exhaust so as to minimize disturbance of 

dust in a dust-filled environment.

 

Where dust or fumes are created, the priority shall be 

to control them at the point of emission.

 

All integral features or accessories for the collection, 

extraction or suppression of airborne dust or fumes 

should be correctly used and maintained in accordance 

with the manufacturer’s instructions.

 

Select, maintain and replace the consumable/inserted 

tool as recommended in the instructions, to prevent an 

unnecessary increase in dust or fumes.

 

Use respiratory protection in accordance with 

the employer’s instructions and as required by 

occupational health and safety regulations.

 

Working with certain materials creates emissions 

of dust and fumes, causing a potentially explosive 

environment.

NOISE HAZARDS

 

Exposure to high noise levels can cause permanent, 

disabling hearing loss and other problems, such 

as tinnitus (ringing, buzzing, whistling or humming 

in the ears). Therefore, a risk assessment and the 

implementation of appropriate controls for these 

hazards are essential.

 

Appropriate controls to reduce the risk may include 

actions, such as damping materials, to prevent 

workpieces from “ringing”.

 

Use hearing protection in accordance with employer’s 

instructions and as required by occupational health 

and safety regulations.

 

Operate and maintain the grinder as recommended in 

the instructions handbook to prevent an unnecessary 

increase in noise.
