OPERATION
Positioning the Machine
1.
2.
3.
4.
Before operating in a unfamiliar area, walk
around the full length of the proposed site and
check for hidden holes,. drop
-
offs
or
obstacles
that could cause an accident.
Lower stabilizers until they carry the weight of
the backhoe. Place the front end loader bucket
flat on the ground. Lower the loader’s
lift
arms
until weight is removed from front tractor tires.
Level the machine using stabilizers and front
loader before starting to dig.
Stability is very important when operating
backhoe in the extreme swing positions as this
causes weight transfer.
Control Handle Operation
(Figure
18)
1.
Assume your position in the operator’s seat.
2.
When engaging PTO, engine rpm should
always be low. Once engaged, engine
rpm may
be increased to desirable operation speed (not
to exceed
540
rpm).
3.
When becoming familiarwith backhoe controls,
start with
a
lower rpm.
4.
Before operating, perform a functional test by
placing control handles in their various
positions and making certain correct operation
occurs, matching labels on operator’s console.
Pay specific attention to float position of boom.
!
DA
Do
not operate the backhoe
if
functions differ from label; serious injury or
death could occur.
5.
It is not difficult to become a successful
operator. Control lever operating labels (shown
in Figure
18)
are next to the operating control
levers. Study these labels; they will assist you
in becoming familiar with the controls.

Operator’s
Console
Pulling handle
1
up will raise left
stabilizer; pushing down lowers it.
Pulling handle
2
up will raise right
stabilizer; pushing down lowers it.
Pulling left control handle back (toward
A) raises boom; pushing it forward
(toward C) lowers it. Full forward (toward
C) is the float position.
Moving left control handle left (toward
B)
swings boom left; moving it right (toward
D)
swings boom right.
Pulling right control handle back (toward
E)
moves dipperstick down and toward
operator; pushing it forward (toward
G)
moves it
up
and away
from
operator.
Pushing right control handle left (toward
F) curls bucket toward operator; pushing
it right (toward
H)
extends bucket out
away from operator.
