Trencher Controls
This trencher attachment uses the loader
arm lift and the tilt controls of the skid
steer loader. Consult your skid steer
operator’s manual for instructions on how
to operate the lift and tilt controls.
Positioning the trencher to one side or the
other relies on the motion of the prime
mover. To move the trencher to the right,
counter-rotate the skid steer to the right
using the skid steer’s drive controls. To
move the trencher left, counter-rotate the
skid steer to the left using the skid steer’s
drive controls.
The auxiliary hydraulic control of the skid
steer loader will provide hydraulic fluid
flow to make the trencher chain system
rotate as necessary to dig a trench.
With practice, the operation of all the
functions listed above will provide an easy
means to dig a trench.
Before Using Trencher the
First Time
If this is your initial
startup with this attachment on this
machine, check the skid steer’s hydraulic
oil level and add oil, if necessary, before
and after doing steps 1- 3 below.
After starting skid steer, lift the
attachment 12” (305mm) off the ground
surface:
1. With the skid steer engine RPMs just
above idle, engage the auxiliary
hydraulic flow to the trencher circuit.
Rotate the digging chain to eliminate
any air in the circuit.
2. Return trencher to the level position
and rest the attachment on the
ground.
3. Apply the brake and shut off the skid
steer’s engine and exit the operator’s
compartment.
4. Check the skid steers hydraulic oil
level, and add oil if necessary.
5. Inspect the trencher’s hydraulic
plumbing for any noticeable leaks.
Correct these leaks before
continuing.
Getting Familiar with the
Attachment
Never operate the
trencher when bystanders are within 20’
(6 m) of your work area. Flying debris or
trench cave-in could result in Death or
Serious Injury.
Be cautious when
operating on un-level ground surfaces. A
machine roll over could result in Minor or
Serious Injury. Always wear your seat
belt when operating this attachment.
