BULLDOZER PUSH ARMS
IMPORTANT: Disconnected hydraulic lines must be capped with the correct size plastic cap.
If caps are not available, use tape or rubber stoppers. Openings must never be plugged with rags.
This practice could introduce dirt or lint into critical hydraulic components. Tag all disconnected
lines to facilitate proper installation.
