PTO HYDRAULIC PUMP (OPTIONAL)

Instructions for engaging and disengaging the
■
PTO are in your tractor manual. Learn how to dis-
engage PTO quickly should an emergency occur.
 Operate tractor PTO at 540 RPM. Do not exceed.
An optional tractor-driven PTO pump is available. The
tractor-driven PTO pump supplies hydraulic pressure
for backhoe operation.
When engaging hydraulic PTO mounted pump, engine
RPM should always be low. Once engaged, engine
RPM may be increased to desirable operation speed.
IMPORTANT: Never exceed 540 RPM. Operating the
pump in excess of 540 RPM will cause overheating
and equipment damage.

GENERAL OPERATION

 Place and keep 3-point lift quadrant lever in low-
ered position at all times.
 If tractor is equipped with draft sensing control,
set control to "HEAVY" (minimum sensitivity) posi-
tion.
 Do not use backhoe for craning; it is primarily
designed for digging. Mechanical failures such as
hose rupture will cause a load to drop suddenly.
 Never allow children or untrained persons to
operate equipment.
 Do not drive tractor with material in backhoe
bucket.

POSITION THE MACHINE

Place and keep 3-point lift quadrant lever in
■
lowered position at all times.
If tractor is equipped with draft sensing control,
■
set to "HEAVY" (minimum sensitivity) position.
Do not dig with backhoe unless stabilizers are
■
down on firm surface.
Before operating in an unfamiliar area, walk around the
full length of the proposed site and check for hidden
holes, drop-off or obstacles that could cause an acci-
dent.
Disengage transport lock pin and swing lock pin. Place
pins in storage position and secure with lock pins pro-
vided (see Transportation section for storage location).

Lower stabilizers until they carry the weight of the back-
hoe (see Control Handle Operation section for
instructions on operation of stabilizer controls). If trac-
tor is equipped with a front loader, place the bucket flat
on the ground. Lower loader 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

CAUTION
When operating controls, always sit in backhoe
■
seat.
It is not difficult to become a successful operator. Your
backhoe is equipped with control lever operating
decals on both the left and right side of your operator's
console as seen in Figure 5. Study these decals; they
will assist you in becoming familiar with the controls.
When becoming familiar with backhoe controls, start
with a lower tractor engine RPM.
Before operating, perform a functional test by placing
the control handles in their various positions and mak-
ing certain correct operation occurs, matching decals
on operator's console. Pay specific attention to float
position of boom. See Boom and Swing Controls
section
WARNING! Do not operate backhoe if control functions
differ from control decals; serious injury or death could
occur.
STABILIZER CONTROLS
Pushing handle 1 forward will lower left stabilizer; pull-
ing back raises it.
Pushing handle 4 forward will lower right stabilizer;
pulling back raises it.
BOOM AND SWING CONTROLS (Handle 2, Figure 5)
Pulling the handle back (towards A) raises boom;
pushing it forward (toward C) lowers it.
Full forward (toward C) is the float position. Moving the
backhoe's Boom Control into the float position relieves
all pressure from the boom hydraulic cylinder. That
allows the boom to move up, or down freely as dipper
and bucket controls are operated.
WARNING! If the backhoe bucket is not in contact with
the ground, moving to float will allow the backhoe to
drop quickly to the ground. Only use the float position
when the bucket is on the ground.
Moving handle left (toward B) swings boom left; mov-
ing it right (toward D) swings boom right.
