Safety Operation & Maintenance Manual Safety chains/breakaway cable and their adjustment (where fitted). Ensure breakaway cable is securely coupled to the towed compressor and also to a substantial anchorage point on the towing vehicle. Ensure cable length is as short as possible, while still allowing enough slackness for the towed compressor to articulate without the brake being applied. Attach safety chains to the towing vehicle at substantial anchorage points of suitable strength. Ensure effective chain length is as short as possible while still allowing normal articulation of the towed compressor and proper operation of the breakaway cable. 17
