Safety

Hydraulic connections

Wear safety shoes

During all work at the machine never bring your feet under the machine and always wear safety shoes. Wearing safety shoes prevents and decreases the risk of serious injuries.

Before hitching the machine always:

• Prevent the tractor and machine from rolling away.

• Switch off all hydraulic systems.

• Switch off the tractor engine.

• Remove the ignition key.

• Never stand between the tractor and the machine during hitching.

In case of negligence serious or deadly injuries can occur.

Ensure the tractor is safe to use

Make sure that the tractor:

• Is in safe and good operating condition.

• Has adequate braking capabilities for the machine.

• Is able to carry and transport the machine.

A tractor which is not in a proper working condition can cause serious personal and material damages.

Hydraulic connections only pressureless

Only connect hydraulic hoses to the tractor when all hydraulic systems are pressureless. Hydraulics under pressure can cause accidental movements of the machine with serious damage and injuries as a result.

Avoid oil mixture

If the machine is used at different tractors improper oil mixtures can occur, which may destroy tractor and machine parts.

Avoid entering of dirt into the hydraulic system

The hydraulic system can get seriously damaged by dirt. Personal injuries or material damage can be caused.

Check hoses and connections

Before connecting, check all hydraulic hoses for damages. After connecting, check all hydraulic hoses for tight connection. Defective hydraulic hoses or incorrect positioned hydraulic connectors can cause unforeseen movements of the machine. Serious damage or fatal injuries can occur.

Secure hydraulic devices

In transport position, secure the hydraulic control devices at the tractor against unintended actuation and lock if possible. Unintended actuation of the hydraulic device may lead to unexpected movements of the machine. Fatal injuries and serious damage can be caused.

Check correct position and layout of hydraulic hoses
