Setup
Proper set-up and bracing is necessary for efficient rod pushing and pulling. Rod pushers can be used with
three configurations: trench box, back brace, and T-bar. Set-up and bracing procedures depend on
configuration used. Follow set-up instruction for configuration you are using.
Trench Box
1. Dig starting trench at least 3’ (1 m) wide, at least 9’ (3 m) long, and as deep as desired bore. Maximum
trench depth depends on job type. For information on soil typing, read US Department of Labor
Regulations on Excavating and Trenching, Part 1926, Subpart P.
2. Level and compact trench floor.
IMPORTANT: In muddy or unstable soils, place boards across trench floor to support trench box. Level
boards before installing trench box.
3. Dig target trench deep enough to meet bore and long enough to remove rod. Keep spoil on one side of
trench and at least 4’ (1.2 m) away.
4. If trench is deeper than 4’ (1.2 m), install trench box extensions.
5. Fasten chains to lift points, lower trench box into starting trench, and position it.
6. Lower rod pusher into trench.
