C - Black (single-line brake)

D - Air Pressure Gauge

Air brake is a combined single-line and dual-line system. Trailers with single-line brakes may be connected at connection (C). Trailers with dual-line brakes may be connected at connections (A) and (B).

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

CAUTION: Single-line trailer brake may be used at speeds up to 25 km/h only.

Keep within legal speed limit.

IMPORTANT: With trailer connected, do not drive away unless air pressure gauge (D) is indicating at least 810 kPa (8.1 bar; 117 psi).

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

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

CAUTION: When operating with a trailer:

1. Remember to set manually-operated brake valve on trailer's air brake system (if equipped) in accordance with weight of trailer's load.
2. Manually draining water from compressed air tank is not necessary, as air tank has an auto-drain function.

NOTE: Green zone on gauge (D) indicates operating range. Loss of pressure may cause the brake to become less effective. Operate the trailer in accordance with the manufacturer's instructions.
