Move dipperstick away and curl bucket by moving lever
back and to the right.
Move dipperstick away and extend (dump) bucket by
moving lever forward and to the right.
Move dipperstick toward operator and extend bucket by
moving lever back and to the right.
The two operations of the boom and swing lever combined
with the two operations performed by bucket and
dipperstick control lever provide four simultaneous
operations of the two levers. Oil flow will go to operation
which requires the least pressure. The ability to feather
valve spools and balance pressure comes with experience
resulting in reduced cycle times.
LEFT HAND STABILIZER
Push lever forward, left hand stabilizer lowers. Pull lever
back, left hand stabilizer raises.
RIGHT HAND STABILIZER
Push lever forward, right hand stabilizer lowers. Pull lever
back, right hand stabilizer raises.
OPERATING BACKHOE
CAUTION: To avoid possible injury, observe
the following safety rules BEFORE
OPERATING backhoe.
• Operate from backhoe operator’s seat only.
• Lower stabilizers until weight of tractor is supported
by stabilizers. Do not lift tractor tires off ground.
• Do not dig near stabilizers.
• Do not attempt to raise tractor off ground or move
tractor forward or backward using backhoe
dipperstick or bucket.
• Do not lose stability by swinging bucket downhill
when positioned on a slope.
It is not difficult to become an efficient operator. Control
operating decals are located in front of control levers. Study
these decals. They will assist you in becoming familiar with
the controls.
Smooth, light handling of controls will result in the most
efficient backhoe operation.
Operate backhoe control levers to become familiar with
their speed and movements. Engine speed will determine
speed of cylinder operation.
Swing boom several times to practice controlling the speed
of swing. Do not operate swing more than 45 degrees each
way for the first few times. Gradually increase the arc.
Best results are obtained by digging near center of swing
arc so material can be dumped on either side.
As operator becomes more familiar with operation of
backhoe, it will be common practice to operate two controls
at one time. For example, with bucket extended and
dipperstick extended, the lift control and crowd control can
be operated together to bring bucket toward operator with
down pressure on it. As dipperstick approaches operator,
the crowd and bucket controls can be operated together to
close bucket and trap material. At end of stroke, lift and
crowd controls are operated to move load up and away
from operator to save time in clearing excavation.
This dual operation of controls will speed and simplify
digging operation. Normally two or more movements will
not be equal or even simultaneous, but as pressure within
the cylinders and resistance of an operating member of
backhoe lessens, it will begin to move. It is balancing the
force of one member against another.
NOTE: Actuating bucket is the key to powerful digging.
Operating the crowd and bucket controls simultaneously
will insure a full bucket and prevent wasted motion and
time.
