What is what

The machine can be divided into two main parts. These can be identified 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 “floating” effect for the head.

The floating gives the head a self-leveling effect, negat- ing the need to adjust the height of the head as the machine passes over floor 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.
