4.9 Control devices
1. Lifting point
Used for lifting the machine with a crane or lift.
2. Control box
The control box has a connection for electrical power, a green start-button and a red stop-button.
Pressing the green start-button will start the electrical motor, and the drum will start rotating.
Pressing the red stop-button cuts off the power to the motor, and the drum will stop rotating.
3. Quick lift lever
In the upright position the drum is lifted off of the ground, in the downwards position, the drum is put
on the ground. The quick lift lever enables the operator to lift the complete drum without changing the
fine adjustment of the working depth, or for easy transport. The lever must be in the upright position
before start-up, in order to prevent a run out of the motor under full load.
Squeeze in the handles of the quick lift lever and pull or push it in the desired position until it clicks
into place.
4. Dust hose connection
The dust hose to the dust collector must be connected here. Use hose clamps and industrial tape for a
reliable connection.
5. Fine adjustment
The working depth can be adjusted by turning the fine adjustment wheel. The scarifying depth must be
adjusted considering the surface to be treated. The flails or cutters must be unhindered thrown up
through the centrifugal force and they must turn free over the lateral axle. When the depth adjustment
is correctly selected, the scarifier will run quiet and constant. Oval worn flails or cutters as well as
broken drum axles indicate a too "high" scarifying depth adjustment.
6. Brake
The brake is foot operated. Use your left foot to click it on or off the left wheel.
