OPERATING INSTRUCTIONS
ANGLE GRINDER CONTROLS (PICS. 2 & 3)
Looking at the Angle Grinder from the top the spindle lock
is located at the front centre of the gearbox casing (Pic.2).
The location points for the handle (to suit left or right handed
operators) are located each side of the grey gearbox housing
correctly. The angle grinder must not be used without the guard
fitted.
Personal protective equipment suitable for the work being carried
out should be worn. Personal protective equipment should
include, suitable work gloves, ear protection, eye protection,
respiratory protection and steel toe cap shoes or boots..
Only use grinding or cutting disc suitable for the work being
done and observe all safety instructions and restrictions of use.
Use of the wrong type of grinding or cutting disc could result in
serious injury.
When using a cutting disc, the disc should be prevented from
jamming in the cut by the use of side pressure. When cutting off
the cutting disc should be placed in the cutting gap in a straight
position.
When using a grinding disc the angle between the grinding disc
and work piece should be between 30° and 40°.
Before placing the angle grinder on the workbench or floor it
must be switched off and the grinding or cutting disc must have
stopped rotating.
Angle grinders must not be used above shoulder height.
Grinding or cutting discs must not be run at a rotational speed
greater than that shown on the grinding or cutting disc.
Cutting discs must not be used for face or side grinding.
Grinding and cutting discs must be used dry. Using water is
highly dangerous and could result in an electric shock.
Do not use discs that are larger than specified, only use discs
that are rated for the angle grinder.
The rotational speed (RPM) shown on the disc should always be
HIGHER than the rotational speed (RPM) of the angle grinder.
