Switching On/Off - Protool AGP125-11D Notice Originale

7 Activation
WARNING
Risk of injury, if the tools are used with
wrong supply power.
Check that the information on the manufacturing
label complies with the actual power supply voltage.
Check that the plug type is the same as the socket
type.
Tools designed for 230 V may be connected to 220 V /
240 V power supply.
7.1 Switching on – off
Switching on
Move the switch button [1-4] forward and the de-
vice will switch on. If you press the front part of
the button, it will arrest and start continual opera-
tion.
Switching off
Press the rear part of the button [1-4] to relax ar-
rest. The button returns to switched-off position.
7.2 Motor electronics
Starting current limitation
Electronically controlled continual running secures
device acceleration without back thrust. Due to
starting current limitation in the device, 16A pro-
tection is suffi cient.
WARNING
Devices without starting current limitation
need higher protection – at least 16A circuit
breaker.
Switching off during back thrust
During sudden drop of revolutions, for example
blocking in dividing cut, the current input in mo-
tor stops. For re-starting, the device must be fi rst
switched off and again switched on.
Protection against re-starting
Prevent uncontrolled starting of the device after
current supply cut off. For re-starting, the device
must be fi rst switched off and again switched on.
Revolutions pre-setting
Use the revolutions regulator [1-5] for smooth
revolutions pre-setting.

Constant electronics
Constant electronics maintains revolutions during
operation and idle run near the constant. Regular
operating shift is achieved.
Protection from overloading dependant on
temperature
The safety electronics switches to cooling regime
when the critical temperature is reached. Motor
continues running at approximately 2500 min
revolutions, constant electronics is deactivated.
After cooling to approximately 10 – 20 s, the device
is fully operational.
Heat protection for devices heated during opera-
tion, reacts adequately sooner.
7.3 Turning the gear box [fi gure 8]
For special cases, the gearbox can be turned in
steps of 90°. This achieves a better handling posi-
tion of the switch.
For such work, we recommend to use the services
of PROTOOL.
Remove four screws. Carefully, turn the gearbox
into required position. Make sure the gearbox does
not separate from motor box by more than ap-
proximately 1 mm.
Insert and fasten the four screws.
8 Grinding and cutting discs
WARNING
Electric shock hazard.
► Make sure you pull the plug out of the socket
prior to any handling the instrument.
► Check that the label on the disc shows the per-
missible peripheral speed or permissible revolu-
tion speed.
► If the permissible revolution speed is given on
the disc, it must not be lower than the highest
no-load speed of the grinder.
► Discs with a permissible peripheral speed of
80 m.s and higher may be used.
–1
► Test new cutting discs by letting them run for
about one minute with no load.
► Unbalanced or vibrating discs should not be used
and should be discarded.
► Protect grinding discs from shock, impact and
lubricants.
► If the grinding and cutting wheels are worn
down to the mark on the wheel guard (see the
arrow sign), they should be replaced with new
ones. This maintains the optimum grinding and
cutting performance of the machine (peripheral
speed of the grinding and cutting wheels).
