Additional Safety Precautions : For Angle Grinders

15 - 30O

(1) (2)

Always wear a good pair of industrial gloves to avoid potential injury from sparks and debris.

Always keep the mains cable well away from the tool. Ensure an adequate electrical supply is close at hand so that the operation is not restricted by the length of the cable.

Always switch the tool OFF immediately when the task is completed.

Always ensure the grinding wheel or cutting disc is fully tightened before use.

Always ensure the wheel / disc is not touching the work when switching ON.

Always allow the Grinder to run briefly before using. Check for vibration which could indicate poor balance or installation of the wheel/disc.

Always hold the tool firmly in BOTH hands (as shown in figure (1)).

Never use excessive force. It should only be necessary to use a little more than the weight of the tool. If the rotational speed drops abnormally, reduce pressure immediately. Forcing the tool and excessive pressure can cause dangerous disc breakage and/or damage to the tool.

Never allow the ventilation slots in the tool to become blocked.

Never use the tool with the guard removed. If the guard becomes damaged, it must be replaced

Never use the tool in a confined space which may limit body movement.

Use only wheels/discs designed for their specific function. (see page 11)

Beware of flying sparks. Hold the grinder at an angle of 15 - 30O to the workpiece surface (as shown in figure (2)).

IMPORTANT: If this appliance is fitted with a plug which is moulded on to the electric cable (i.e. non- re-wireable) please note:

1. The plug must be thrown away if it is cut from the electric cable. There is a danger of electric shock if it is subsequently inserted into a socket outlet.

2. Never use the plug without the fuse cover fitted. 3. Should you wish to replace a detachable fuse carrier, ensure that the correct

replacement is used (as indicated by marking or colour code). 4. Replacement fuse covers can be obtained from your local dealer or most electrical

stockists. 5. The fuse in the plug must be replaced with one of the same rating (13 amps)

and this replacement must be ASTA approved to BS1362.

IMPORTANT: If in any doubt, do not attempt any electrical repair yourself. Consult a qualified technician

VIBRATION EMISSIONS

Employers are advised to refer to the HSE publication Guide for Employers. All hand held power tools vibrate to some extent, and this vibration is transmitted to the operator via the handle, or hand used to steady the tool. Vibration from about 2 to 1500 herz is potentially damaging and is most hazardous in the range from about 5 to 20 herz. Operators who are regularly exposed to vibration may suffer from Hand Arm Vibration Syndrome (HAVS), which includes dead hand, dead finger, and white finger. These are painful conditions and are widespread in industries where vibrating tools are used. The health risk depends upon the vibration level and the length of time of exposure to itin effect, a daily vibration dose. Tools are tested using specialised equipment, to approximate the vibration level generated under normal, acceptable operating conditions for the tool in question. For example, a grinder used at 45 on mild steel plate, or a sander on soft wood in a horizontal plane etc. These tests produce a value a, expressed in metres per second per second, which represents the average vibration level of all tests taken, in three axes where necessary.

HAND-ARM VIBRATION

- 12 -

MODEL No: CAG122 DESCRIPTION: ANGLE GRINDER

Declared vibration emission value in accordance with EN12096

Measured vibration emission value - a: 13.2 m/s2

Value determined according to EN28622-1

a values in excess of 2.5 m/s2 are considered hazardous when used for prolonged periods. A tool with a vibration value of 2.8 m/s2 may be used for up to 8 hours (cumulative) per day, whereas a tool with a value of 11.2 m/s2 may be used for hour per day only.

The graph below shows the vibration value against the maximum time the respective tool may be used, per day. It should be noted that if a tool is used under abnormal, or unusual conditions, then the vibration level could possibly increase significantly. Users must always take this into account and make their own risk assessment, using the graph above as a reference. Some tools with a high vibration value, such as impact wrenches, are generally used for a few seconds at a time, therefore the cumulative time may only be in the order of a few minutes per day. Nevertheless, the cumulative effect, particularly when added to that of other hand held power tools that may be used, must always be taken into account when the total daily dose rate is determined.
