ENGLISH
OPERATING YOUR ANGLE GRINDER (FIG. 1)
To switch on, push the slider switch forward. To switch off, press the rear of the slider switch.
FITTING THE DISCS (FIG. 2 & 3)
Proceed as follows:
• Disconnect the plug from the electricity supply.
• Ensure the guard is fitted. Place the inner flange (FIG. 2-A) on the spindle. Ensure it is located on the two flats.
• Place the abrasive disc on the spindle and inner flange (FIG 2-B). Ensure it is correctly located.
• Fit the threaded outer flange (FIG. 2-C), making sure it is facing in the correct direction for the type of disc fitted. For grinding discs, the
flange (FIG. 2-C) is fitted with the raised portion facing towards the disc. For cutting discs, the flange (FIG. 2-C) is fitted with the inner
portion facing away from the disc.
• Hold the spanner on the flats of the spindle to prevent rotation of the disc and tighten the outer flange with the spanner provided.
• Press in the spindle lock button and rotate the spindle until it locks (FIG. 3). Keeping the lock button pressed in, tighten the outer flange
with the spanner provided.
FITTING SANDING DISCS (FIG. 4)
• Use a sanding disc with the backing pad for sanding with your angle grinder.
• Disconnect the plug from the electricity supply.
• Remove the guard.
• Place the flange on the spindle. Place the backing pad on the spindle and inner flange, ensuring it is correctly located.
• Mount the fibre backed abrasive disc on the backing pad.
• Fit the threaded outer flange and tighten as explained in 'Fitting the discs'.
HANDY HINTS (FIG. 5)
Hold your angle grinder firmly with one hand around the side handle and the other around the body of your angle grinder.
• Always position the guard so that as much of the exposed disc as possible is pointing away from you.
• Be prepared for a stream of sparks when the disc touches the metal.
When grinding, always maintain the correct angle between the disc and the work surface (15°) (FIG. 5). This increases the removal capacity
of the disc and avoids unnecessary overloading.
OVERLOAD
Overloading will cause damage to the motor of your angle grinder. This can happen if your angle grinder is subjected to heavy duty use for
prolonged periods of use. Do not in any circumstances, attempt to exert too much pressure on your angle grinder to speed up your work.
The abrasive discs operate more efficiently when a light pressure is exerted, thus avoiding a drop in the speed of your angle grinder (see
Tool care).
TOOL CARE
Keep guards, air vents and the motor housing as clear as possible of dust and dirt. Wipe with a clean cloth and blow through with a
low-pressure air supply. Excessive build-up of metal dust can cause tracking of electrical current from the internal parts to exposed metal
parts. Do not overload your angle grinder. Overloading causes a reduction in speed and efficiency, causing your angle grinder to become too
hot. If this happens, operate your angle grinder under no load for one or two minutes until it has cooled to normal operating temperature.
Switching your angle grinder off under load will reduce the life of the switch.
CLEANING
Use only mild soap and a slightly damp cloth to clean your angle grinder. Many household cleaners contain chemicals which could seriously
damage the plastic. Also, do not use petrol, turpentine, lacquer or paint thinners or similar products. Never let any liquid get inside the tool
and never immerse any part of the tool into liquid.
IMPORTANT:
To assure product SAFETY and RELIABILITY, repairs, maintenance and adjustment (other than those listed in this manual)
should be performed by authorized service centers or other qualified service personnel, always using identical replacement parts.
ACCESSORIES
Recommended accessories for use with your tool are available from your local dealer or authorized service center.
WARNING:
The use of any accessory not recommended for use with this tool could be hazardous.
