b) Do not use the power tool if the switch does not turn activate or deactivate it. Any power tool that cannot be controlled
with the switch is extremely dangerous and must be repaired.
c) Disconnect the main plug from the power source and/or the battery pack from the power tool before changing accessories,
making any adjustments, or storing power tools. Such preventive safety measures will reduce the risk of starting the power
tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these
instructions to use and operate the power tool.
Power tools are extremely dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts, leakage and any other
condition that may affect the power tool's operation. If damaged, please have the power tool repaired before use. Many
accidents and injuries are caused by poorly maintained power tools.
f) Keep all the cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind
and are more precise and easier to control.
g) Always use the power tool, accessories and tool bits etc. in accordance with the instructions of this instruction manual,
taking into account the working conditions and the work to be performed.
Use of the power tool for applications different from those intended could result in a hazardous situation.
Service
a) Have your power tool serviced by a qualified repair technician using only identical replacement parts. This will ensure that
the safety of the power tool is maintained.
Machine-Specific Safety Warnings
• Do not use grinding disks with a maximal rotational speed inferior to the grinder's maximal rotational speed.
• Do not use damaged grinding disks (cracked, split) or not disks which are not appropriate for the material to be grinded.
• Do not use grinding disks which include a reducing bushing.
• Run off load for 30 seconds, when placing any new or reinstalled grinding disks. Keep bystanders in a safe distance while
testing the power tool. Stop the tool immediately in case you detect excessive vibrations and resolve the problem.
• Tighten the clamping flange sufficiently to solidly hold the grinding wheel.
• Carry out rotational speed measurements at regular intervals and necessarily after having reassembled the tool.
• Check that the guard is correctly set and not damaged before switching the tool on.
• Before starting any work, check the condition of the power supply cable and plug.
• Always unplug the tool before handling it (including replacement of grinding disks).
• Do not brutally apply the grinder on the material, and do not apply too much effort when grinding.
• If the rotation speed reduces abnormally, stop the tool immediately and unplug it from the socket.
• Keep pinion gear and roller bearings correctly greased.
• Keep the grinder clean, especially the unit's air-vents.
• Never use the tool without the protective guard.
• Never press the axle locking button while the grinder is in operation. Before starting any work check that the drive axis
did not remain locked.
• Never use cutting disks sideways (example: chamfering)
• Make sure that the grinding disk's dimensions are compatible with the grinder.
• Grinding disks should be stored or carried with care according to the manu facturer's instructions.
• Make sure the grinding disks are mounted according to the manufacturer's instructions.
• Warning: a grinding wheel continues to rotate after the grinder is switched off.
Kickback and related warnings
• Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other accessory. Pinching
or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in
the direction opposite of the accessory's rotation at the point of the binding.
• For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the
pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump
toward or away from the operator, depending on direction of the wheel's movement at the point of pinching
• Abrasive disks may also break under these conditions.
• Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by
taking proper precautions as given below.
• Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces.
