Husqvarna PG 680 Bedienungsanweisung Seite 9

The machine can be divided into two main parts. These
can be identifi ed as follows:
1. Chassis/Frame section – comprising handle bars,
electrical cabinet, steel frame and wheels.
2. Head – comprising of motors, cover, grinding/satel-
lite/
planetary heads and internal components.
The machine has been manufactured to allow move-
ment between the chassis and head via the connection
point at the lifting lugs and chassis pins. This move-
ment is important during the grinding process as it
creates a "fl oating" effect for the head.
The fl oating gives the head a self-leveling effect, negat-
ing the need to adjust the height of the head as the
machine passes over fl oor areas with different slopes
or undulations.
Control panel
The control panel consists of a number of switches and
dials giving 8 separate controls (see picture).
Power - This button, when depressed, will turn on
power supply to the unit when the EMERGENCY
STOP button has been released.
Emergency Stop - When pushed will immediately
shut down machine by totally stopping power supply to
drives/ frequency converters in electrical cabinet.
Head Speed - Direction control for planetary head rota-
tion.
Fwd/Rev (Yellow) - Direction control for planetary head
rotation.
Disc Speed - Speed control for grinding heads.
Fwd/Rev (Red) - Direction control for grinding heads.
Reset - Will clear fault function/error message on
drive/frequency converter (located in electrical cabinet)
in case of fault occurring.
Stop/Run - To start or stop machine during normal
operation.
IMPORTANT!
It is important to use the STOP/RUN switch
to control the running of the machine, not
the EMERGENCY STOP button. Each time
the EMERGENCY STOP button is pressed
it shuts down the drive/frequency converter.
Frequently powering up and down of the
drive/frequency converter will reduce the life
span of the drive/ frequency converter.

IMPORTANT!
Planetary head and grinding heads are set
to both turn in the same direction (i.e. both in
clockwise rotation or both in counter-clock-
wise rotation).
Clockwise rotation of speed control will in-
crease speed of planetary head and grinding
heads.
