810W 115mm ANGLE GRINDER ENB461GRD
WORKING ADVICE
After heavily straining the power tool, continue to run it at no-load for several minutes to cool down the
cutting/grinding tool.
Grinding and cutting discs become very hot while working; do not touch until they have cooled.
Do not use the power tool with a cut-off stand.
Don’t use the machine near inflammable materials, the flying sparks are very hot and could cause fire or
personal injury.
Always hold the machine so, that the disc is perpendicular to the workpiece. Avoid the disc to jam. A jammed
or blocked disc may crack and cause serious injuries to the user and third persons.
WARNING
Don’t apply heavy pressure to the machine.
Best grinding and cutting results can be obtained by only a slight pressure on the tool; Forcing and excessive
pressure will damage the disk and cause serious personal injury.
INSTRUCTION FOR ABRASIVE WHEELS AND DISCS
Abrasive wheels should not be mounted on makeshift apparatus. They should be mounted on the type of
machine for which they are intended. These appear to be obvious precautions, but accidents still occur
because wheels are mounted on home-made or improvised apparatus quite unsuitable for the work. Likewise,
accidents are caused by heavy wheels being fitted to spindles designed to take only the lightest of wheels. As
a result, vibration is excessive and breakages occur. On no account should an abrasive wheel be screwed on
to the tapered spindle of a buffing machine. This dangerous method of mounting is likely to result in the
breaking of the wheel owing to the wedging action of the tapered spindle.
The new wheels should be carefully unpacked, cleaned with a brush and examined for possible damage in
transit. In unpacking, the careless use of a tool may cause damage to the wheel. The soundness of wheels
can be further checked by tapping them with a light, non-metallic implement. This is known as the ‘ring’ test.
Wheels must be dry and free from sawdust for the ring test otherwise the sound will be deadened. It should
also be noted that organic bonded wheels do not emit the same clear metallic ring as inorganic bonded
wheels. Heavy wheels should be supported on a clean hard floor for the ring test while light wheels should be
suspended from their hole on a finger or small pin. If the wheel sounds dead, for example due to cracking, it
should not be used.
All abrasive wheels are relatively fragile. It should not be assumed that organic bonded wheels (resin, shellac,
rubber) will stand rough handling.
As the wheel wears down in use, the effective peripheral surface speed will reduce if the rotational speed
remains constant and may result in a reduced grinding efficiency. To make sure the machine work smoothly,
the wheel should be replace with the maximum size less than 80 mm.
