Digging with the Trencher
The following specific guidelines should be followed when
digging with a trencher.
1
Make an initial cut with the trencher boom
1
lying flat
along the ground.
2
As the chain is rotating begin inserting the nose of the
boom into the ground as
A
while slowly raising the
trencher a few inches off the ground as
B
. Both of
these operations should be done gradually
(see the
Carrier Operator Manual - Loader Controls
)
.
3
Gradually establish the trencher boom angle. Best
results will be obtained with an angle between 45
o
and
60
o
. The skid shoe
2
should be just above ground
level. Make certain the trench cleaner
3
is operating
freely if fitted.
4
The digging chain should rotate anticlockwise as at
C
when viewed from the drive chain casing
4
side.
5
Whenever possible always dig along the centre line of
the trench. This makes it easier to control the
machinery and dig a straight trench.
6
Gently creep the carrier backwards as at
D
. Too fast a
speed will cause the trencher to stall.
7
Control the depth by adjusting the boom controls of
the carrier
(see
Operator Manual - Loader Controls
)
.
8
Do not engage the ‘float’ control of the arm and
attachment if fitted as this increases the drag on the
system.
