7 Handling
7.1 Switching On and Off
Danger
– Tool bursting!
The tool can burst due to the speed being set too high! Check the set speed before starting.
WARNING
– Rotating parts!
Avoid unintentional starting: Always switch the machine off when the plug is pulled out of
the socket or if there has been an interruption in the power supply.
Ensure that other persons are at a safe distance from the working area.
Wear personal protective equipment in the work area!
CAUTION
– Risk of injury!
Before switching on, hold the handpiece with clamped tool firmly in your hand! Pay
attention to clothing, hair and objects that may be caught by the tool.
CAUTION
– Machine continues running!
The shaft continues to run on after the machine has been switched off. Do not remove the
tool until the spindle is stationary!
ATTENTION
– Tool damage due to inappropriate speed!
An overspeed can cause vibrations and lead to damage to the tool and shaft!
When selecting the speed, observe the max. permissible working speed of the tool
manufacturer, the shaft and the handpiece! Only use tools within the permissible speed
range of the machine.
Switching on
Plug in the mains plug before switching on.
Switch on the drive unit control with the rotary switch (1) to "On".
The frequency converter takes a few seconds to become operational.
Use the potentiometer (2) to preselect the speed.
