7.1. MOWER SAFETY ELEMENTS
The mower is controlled by a radio remote controller. This means that the operator is not permanently near the
mower and cannot use the controllers placed directly on the mower. For the safety of the operator as well as
other person the following chart lists various situations and protective measures taken:
Command EMERGENCY STOP (automatic or manual) has the following effects:
1. Engine is stopped
2. Wheel steering is blocked
3. Wheel drive is blocked
4. Starter is blocked
5. Engine brake is engaged
6. Ignition is turned off
EMERGENCY STOP command is activated if:
1. mower get out of the signal range
2. radio connection is interrupted / interfered with
3. another machine on the same frequency channel works nearby
A safety block prevents the engine from starting if:
1. there is no connection between the RC and control unit of the mower
2. confirmation button on the RC is not pressed
3. drive servomotor is not in the neutral position
4. engine brake is activated
In case the mower rolls over the engine brake is activated automatically. This ensures quick stopping of
the mowing blade.
