Operating the Machine
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, with
propel motors to the rear of the machine. Clean cave-in
from the side of the trench.
When trenching across a slope, level the machine so that
bottom of trench will be level. Level machine by
counterrotating tracks or by digging a shelf.
Place the spoil pile on the upper side of the trench. The
machine is more stable and backfilling is easier.
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) behind the first (A).
Use the stakes as a sight gauge. They are especially
helpful if the machine is moved often.
