Investigate and take corrective action to eliminate the cause of wheel binding.
d) Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully
re-enter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece.
e) Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near
the line of cut and near the edge of the workpiece on both sides of the wheel.
f) Use extra caution when making a "pocket cut" into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.
2.2.6 SPECIFIC SAFETY INSTRUCTIONS FOR ANGLE GRINDERS
Check that the maximum speed indicated on the grinding disc corresponds to the maximum speed of
the machine. The speed of the machine must not exceed the value on the grinding disc.
Make sure that the dimensions of the grinding disc correspond to the specifications of the machine.
Make sure that the grinding disc has been mounted and fastened properly. Do not use reducing rings or
adapters to make the grinding disc fit properly.
Treat and store grinding discs in conformance with the supplier's instructions.
Do not use the machine for grinding workpieces with a maximum thickness exceeding the maximum
grinding depth of the grinding disc.
Do not use grinding discs for deburring.
When grinding discs have to be mounted on the thread of the spindle, make sure that the spindle has
sufficient thread. Make sure that the spindle is sufficiently protected and does not touch the grinding
surface.
Before use, inspect the grinding disc for any damage. Do not use grinding discs which are cracked,
ripped or otherwise damaged.
Before use, let the machine run idle for 30 seconds.
Immediately switch off the machine in case of abnormal vibrations or occurrence of another defect.
Carefully inspect the machine and grinding disc before switching the machine on again.
Make sure that sparks do not put people into danger or that they contact highly flammable substances.
Make sure that the workpiece is sufficiently supported or clamped. Keep your hands away from the
surface to be cut.
Always wear safety goggles and hearing protection. If desired or required also use another kind of
protection like for example an apron or helmet.
Ensure that mounted wheels and points are fitted in accordance with the manufacturer's instructions.
Ensure that blotters are used when they are provided with the bonded abrasive product and when they
are required.
If a guard is supplied with the tool never use the tool without such a guard.
For tools intended to be fitted with threaded hole wheel, ensure that the thread in the wheel is long
enough to accept the spindle length.
Ensure that ventilation openings are kept clear when working in dusty conditions.
2.2.7 SAFETY INSTRUCTIONS FOR BATTERIES AND CHARGER
Batteries
Never attempt to open for any reason.
Do not store in locations where the temperature may exceed 40° C (104° F).
Charge only at ambient temperatures between 4° C and 40° C (39.2° F and 104° F).
Charge only using the charger provided with the tool.
Store your batteries in a cool dry place (5° C-20° C/41° F-68° F). Never store batteries in discharged state.
It is better for Li-ion batteries to discharge and reload them regularly (at least 4 times a year). The ideal
charge for long-term storage of your Li-ion battery is 40% of capacity.
