for T
the area of trash, branches and rocks before
trenching to prevent equipment damage.
Always begin trenching with the slowest ground speed
possible. Increase speed if conditions permit.
Always use full throttle (maximum engine speed)
when trenching.
Always trench backwards (i.e., in reverse).
Never transport the trencher with the loader arms
raised. Keep the arms lowered and the trencher tilted
up.

• Y
ou will be able to dig a trench faster by controlling
the depth with periodic adjustments of the loader arms.
•
Use low range (turtle position) for best performance
and smoothest operation. Adjust the flow divider
valve to approximately the 10 o’clock position.
•
If the trencher binds in the soil, push the auxiliary
hydraulics lever fully forward to reverse the chain
direction. Once the chain is loose, pull the lever
rearward again and continue trenching.
