Trenching
Be sure the digging chain is not turning when the engine is at an idle. Be sure the engine is
off or at an idle before moving the trencher at the job site.

NOTE: All depths are approximate. Actual depth may vary depending upon
soil conditions and trencher blade wear.
Also, soil conditions and operator experience will dictate actual trenching action and speed.
A general description on how to trench:
1.
With the engine running and at an idle and the depth control in the depth “0”, apply
downward pressure on the handle to raise the digging chain.
2.
Lift the depth control handle and slowly move the lever forward into the desired depth
notch.
3.
Apply downward pressure to the handlebar so the digging chain is not in contact with
the ground. Increase the engine speed and hold on to the handlebar with both hands.
Slowly relieve the downward pressure on the handlebar allowing the digging chain to
penetrate the soil until the chosen depth is reached.
