16 Checking the Controls
To switch the blower on:
► Unlock the retaining latch (1) by pushing it forward with
your thumb. Hold it in this unlocked position.
► While holding the retaining latch, squeeze the trigger
switch (2) with your index finger.
The blower will activate.
The motor will not switch on unless the retaining latch is
pushed forward and the trigger switch is pressed at the
same time. Once the trigger switch is activated, you may
release the retaining latch. Holding the Ergo-Lever (3) down
keeps the trigger switch unlocked.
The further the trigger switch is depressed, the stronger the
blowing force.
If you releases the trigger switch and Ergo-Lever, you have
to unlock the tool again with the retaining latch.
15.2 Switching Off
WARNING
To reduce the risk of personal injury from unintended
