Dust/Chip Extraction
Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Operation
Start-up
Inserting the battery
Push the charged battery (7) into the base of the power tool
from the front until the battery is securely locked.
Switching on/off
To start the power tool, push the on/off switch (5) forward.
To lock the on/off switch (5) in position, push the on/off
switch (5) forward and down until it clicks into place.
To switch off the power tool, release the on/off switch (5);
or, if the switch is locked, briefly push the on/off switch (5)
backward and down and then release it.
Always check abrasive tools before using them. The
u
abrasive tool must be fitted properly and be able to
move freely. Carry out a test run for at least one
minute with no load. Do not use abrasive tools that are
damaged, run untrue or vibrate during use. Damaged
abrasive tools can burst apart and cause injuries.
Kickback stop
If there is a sudden kickback in the power tool,
e.g. jamming in a separating cut, the power
supply to the motor will be interrupted elec-
tronically. The kickback stop indicator(29)
then lights up. When kickback stop is activ-
ated, the status indicator (33) flashes red.
To restart the tool, set the on/off switch (5) to the off posi-
tion and then switch the power tool on again.
Restart protection
The restart protection feature prevents the power tool from
starting unintentionally after the power supply to it has been
interrupted.
When restart protection is activated, the status indicator
(33) flashes red.
To restart the tool, set the on/off switch (5) to the off posi-
tion and then switch the power tool on again.
