7.5
Setting impact force and speed
Turn the adjusting wheel (8) to the desired value.
The higher the number, the greater the speed and
the higher the impact force.
The correct setting is found by trial and error.
Example: if soft, brittle materials are being
chiselled, or cracking is to be kept to a minimum,
set the adjusting wheel to "1“ to "2“ (low impact
force).
For demolition or for drilling into harder materials,
set the adjusting wheel to the highest number
(max.power).
7.6
Switching On and Off
To switch on:
press the trigger switch (5).
To switch off:
release the trigger switch (5).
When working with the chisel hammer, only a
moderate amount of press-on pressure (approx.
20 kg) is required. High press-on pressure does
not increase work capacity and can possibly
shorten the service life of your tool.
In the case of deep bores, pull the drill bit out of the
bore from time to time in order to remove the stone
dust.
Motor cleaning: blow out the machine regularly
and thoroughly through the air slots with
compressed air.
