As Needed
Check Trench Cleaner Position
Check trench cleaner position (if equipped)
anytime the digging chain is adjusted or replaced.
The trench cleaner is properly positioned when
there is 3-4 in (76-102 mm) between the digging
teeth and the inside of the trench cleaner shoe
(A).
Check that bolts holding personnel restraint bar/
trench cleaner to arm are tightened to 350 ft•lb
(475 N•m). Apply Loctite 271
®
adhesive.
Time Augers
Ensure that augers are balanced, as shown. If
auger timing is off, unit will bounce from side to
side even in normal digging conditions.
To adjust timing:
1. Remove bolts holding augers to auger shaft
and rotate either auger as needed until
augers are balanced.
2. Reinstall bolts and tighten securely.
