Trenching

Before starting work, walk the site to uncover hazards and to plan the job.

To prevent cave-ins, dig a "V" shaped trench and place spoil piles at least 1 m (3 ft) away from trench. The deeper the trench, the further the spoil pile should be placed from it.

If you have to clean up a cave-in and cannot reach it from machine's present position, DO NOT back over the trench. Drive the machine beside the trench to the cave-in. Park the machine at a 90° angle to trench; clean cave-in from the side of the trench.

For straight line trenching, drive two stakes in at the beginning of the trench. Drive the first stake in immediately behind the starting point and the second stake approximately 9 m (30 ft) (A) behind the first.

Use the stakes as a sight gauge. They are especially helpful if the machine is moved often.
