Using an intermittent pulling action, pull the trencher toward you 4 to 6 inches then
relax your pull, allowing the trencher to again reach the chosen depth.

Refer to the engine manual for the switch location on your trencher. The operator can turn
the trencher off at any time by switching either stop switch to the “OFF” position. Both
switches must be “ON” before the engine can start.

muds or anything which stuck the chain, then restart the engine, and start digging again.
