LX1056680-UN-05JUL12

A - Black (single-line brake, if equipped)

B - Yellow (dual-line brake)

C - Red (dual-line brake, supply)

The air brake is available as dual-line system or as combined single-line and dual-line system. Trailers with single-line brakes may be connected at connection (A). Trailers with dual-line brakes may be connected at connections (B) and (C).

Ensure that the connections are clean before joining the compressed air hoses. Seal the connections with the dust protector caps whenever the hoses are disconnected.

CAUTION: The single-line brake may be used with trailers at speeds up to 25 km/h only.

When driving the tractor, keep within the legal speed limit.

IMPORTANT: With a trailer connected, do not start driving unless the air pressure gauge indicates at least 810 kPa (8.1 bar; 117 psi).

To prevent undue wear on the brakes, observe the following:

• Make sure pressure hoses are connected.
• When driving downhill, select same gear you would for driving uphill.
• Check the air brake on the trailer regularly to make sure that it is functioning correctly.

CAUTION: When operating with a trailer:

1. Remember to set the manually-operated brake valve on the trailer's air brake system (if equipped) in accordance with the weight of the trailer's load.
2. Check the compressed air tank every day for condensation (see Service - Daily or Every 10 Hours)! If condensation is detected, replace the air-drier cartridge.
3. When parking the tractor, always engage the park lock.

NOTE: Loss of pressure may cause the brake to become less effective. Operate the trailer in accordance with the manufacturer's instructions.
