Part II: Familiar with Your Trencher

It may be helpful to familiarize yourself with the controls and features of the Trencher.
If you have any question, please contact the dealers in your area. TECHNICAL SPECIFICATIONS

NOTICE
A. It is your responsibility as the operator of this piece of equipment to know what specific requirements, precautions and work hazards exist. You must read and understand all of the information contained in the user manual.
B. The trencher is a small, operator propelled, chain-type trencher designed for the installation of lines that require a narrow shallow trench. It has more than enough power to trench through the toughest soils, however, because of its small size, low horse power and trench capacity, it is limited in what it is capable of doing. The job site, soil conditions, job specifications and operator experience may dictate that a different tool or method be used to do the job.
C. The digging chain has a tendency to pull the trencher in the opposite direction you want to dig. For this reason, be sure that the digging teeth are not in contact with the ground or other objects while starting the engine and that the wheel lock device engages before lowering the digging bar into the ground. Be sure that you have a firm grip on the machine and are ready to control it when the digging bar comes in contact with the ground.
D. The trencher has a tendency to “hop” or “buck” under certain conditions. This can be the result of certain soil conditions or buried objects that the trencher cannot cut through or lift to the surface. The trencher must be stopped and the object removed, or restarts the trench beyond the object.

PART III: Operating the Trencher

It may be helpful to better familiarize yourself with the features of your Trencher before beginning the steps outlined in this chapter.
