GENERAL INFORMATION
The purpose of this manual is to assist in setting up,
operating and maintaining your backhoe. Read it care-
fully. It furnishes information and instructions that will
help you achieve years of dependable performance.
These instructions have been compiled from extensive
field experience and engineering data. Some informa-
tion may be general in nature due to unknown and
varying conditions. However, through experience and
these instructions, you should be able to develop pro-
cedures suitable to your particular situation.
The illustrations and data used in this manual were cur-
rent at the time of printing, but due to possible in-line
production changes, your machine may vary slightly in
detail. We reserve the right to redesign and change the
machines as may be necessary without notification.
■ Some illustrations in this manual show the
backhoe with safety shields removed to provide a
better view. The backhoe should never be operated
with any safety shielding removed.
Figure 1. Backhoe Directions
Throughout this manual, references are made to right,
left, forward and rearward directions. These are deter-
mined from the backhoe operator seat position facing
rearward as shown in Figure 1.
Terms for backhoe components have some variations
throughout the industry. We use SAE designations as
shown in Figure 2.

INSTALLATION
Hydraulics must be connected as instructed in
this manual. Do not substitute parts, modify, or
connect in any other way.
After connecting hoses, check that all control
lever positions function as instructed in the Opera-
tor's Manual. Do not put into service until control
lever and equipment movements are correct.
TRAINING
Safety instructions are important! Read all
attachment and power unit manuals; follow all
safety rules and safety decal information. (Replace-
ment manuals and safety decals are available from
your dealer. To locate your nearest dealer, check
the Dealer Locator at www.WoodsEquipment.com,
or in the United States and Canada call 1-800-319-
6637.) Failure to follow instructions or safety rules
can result in serious injury or death.
If you do not understand any part of this manual
and need assistance, see your dealer.
Know your controls and how to stop engine and
attachment quickly in an emergency.
 Operators must be instructed in and be capable
of the safe operation of the equipment, its attach-
ments, and all controls. Do not allow anyone to
operate this equipment without proper instructions.
Keep hands and body away from pressurized
lines. Use paper or cardboard, not hands or other
body parts to check for leaks. Wear safety goggles.
Hydraulic fluid under pressure can easily penetrate
skin and will cause serious injury or death.
Make sure that all operating and service person-
nel know that if hydraulic fluid penetrates skin, it
must be surgically removed as soon as possible by
a doctor familiar with this form of injury or gan-
grene, serious injury, or death will result. CON-
TACT A PHYSICIAN IMMEDIATELY IF FLUID
ENTERS SKIN OR EYES. DO NOT DELAY.
Never allow children or untrained persons to
operate equipment.
PREPARATION
Check that all hardware is properly installed.
Always tighten to torque chart specifications
unless instructed otherwise in this manual.
Air in hydraulic systems can cause erratic oper-
ation and allows loads or equipment components
to drop unexpectedly. When connecting equipment
or hoses or performing any hydraulic maintenance,
purge any air in hydraulic system by operating all
hydraulic functions several times. Do this before
putting into service or allowing anyone to
approach the equipment.
After connecting hoses, check that all control
lever positions function as instructed in the Opera-
tor's Manual. Do not put into service until control
lever and equipment movements are correct.
Protective hose sleeves must cover all hydrau-
lic hoses within 20 inches of the operator and be
secured onto metal hose fittings. Replace hoses or
sleeves if damaged or if protective sleeve cannot
be properly positioned or secured.
Make sure all hydraulic hoses, fittings, and
valves are in good condition and not leaking before
starting power unit or using equipment. Check and
route hoses carefully to prevent damage. Hoses
must not be twisted, bent sharply, kinked, frayed,
pinched, or come into contact with any moving
parts. Operate moveable components through full
operational range to check clearances. Replace
any damaged hoses immediately.
Always wear relatively tight and belted clothing
to avoid getting caught in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head;
and respirator or filter mask where appropriate.
Make sure spring-activated locking pin or collar
slides freely and is seated firmly in tractor PTO
spline groove.
Make sure attachment is properly secured,
adjusted, and in good operating condition.
Power unit must be equipped with ROPS or
ROPS cab and seat belt. Keep seat belt securely
fastened. Falling off power unit can result in death
from being run over or crushed. Keep foldable
ROPS system in “locked up” position at all times.
Safety is a primary concern in the design and
manufacture of our products. Unfortunately, our
efforts to provide safe equipment can be wiped
out by an operator’s single careless act.
In addition to the design and configuration of
equipment, hazard control and accident preven-
tion are dependent upon the awareness, con-
cern, judgement, and proper training of
personnel involved in the operation, transport,
maintenance, and storage of equipment.
It has been said, “The best safety device is an
informed, careful operator.” We ask you to be
that kind of operator.
