Stopping the Machine
To stop the machine, release the traction control, move
the throttle lever to slow (turtle), lower the boom to
the ground, and stop the engine. Set the parking brake
and remove the key.
A child or untrained bystander could attempt to
operate the machine and be injured.
Remove the key from the switch when leaving
the machine, even if just for a few seconds.
Moving a Non-functioning
Machine
Important: Do not tow or pull the machine
without first opening the tow valves, or the
hydraulic system will be damaged.
1. Stop the engine.
2. Remove the bottom shield.
3. Using a wrench, turn the tow valves on the hydraulic
pumps twice counter-clockwise (Figure 22).

4. Install the bottom shield and tow the machine as
required.
5. When the machine has been repaired, close the tow
valves before operating it.
Digging a Trench
1. Start the engine, raise the boom, set the throttle
lever to the Fast position, and move the machine
over the area to be trenched.

2. Pull the trencher control lever to the reference bar
to engage the trencher.
3. Slowly lower the boom and chain into the ground.
Note: To achieve the maximum depth, you may
need to lower the boom as far into the ground as
it will go with the chain running. Then, stop the
chain and lower it fully. Start the chain again and
resume operation.
4. Once the trencher boom is in the ground at a 45
to 60 degree angle, slowly move the traction unit
rearward to extend the trench.
Note: If you move too fast, the trencher will stall.
If it stalls, raise it slightly, slowly drive forward, or
reverse the chain direction momentarily.
5. When finished, raise the boom out of the trench,
then stop the trencher.
Securing the Machine for
Transport
When transporting the machine on a trailer, always use
the following procedure:
Important: Do not operate or drive the machine
on roadways.
1. Stop the engine.
2. Lower the boom.
3. Secure the machine to the trailer with chains or
straps using the tie-down/lift loops at the front and
rear of the machine (Figure 23 and Figure 24). Refer
to your local ordinances for trailer and tie-down
requirements.
