SAFE
Most backhoe equipment accidents can be avoided by following simple safety precautions.
These safety precautions, if followed at all times, will help you operate your backhoe safely.
OPERATION
SAFE OPERATION A-1
BEFORE
1.
Know your equipment and its limitations. Allow only
trained personnel to operate or service this equipment.
Read and understand all instructions and precautions
in this manual before service or operation.
Also read and understand all instructions and
precautions found in the tractor and loader operator's
manuals before using this equipment.
2.
For safe operation, check the mounting bolts for
tightness and that the mount levers are in the right
position before operation.
3. Never operate tractor with backhoe attached and
loader removed.
4.
Check for buried material such as electncal,
telephone, gas and water lines. When in doubt,
contact local utility companies for their buried location
prior to operating the backhoe.
5. Replace any safety decal that becomes damaged, lost
or illegible. Also renew all decals when repainting.
OPERATING BACKHOE
OPERATING THE BACKHOE
1.
Do not allow anyone other than the operator on the
unit while in operation or transport.
2.
Use care when operating on slopes to avoid tip-over.
Travel at a speed compatible with safe operation,
especially when operating on uneven terrain, crossing
ditches or while turning.
3. Operate the backhoe from the backhoe operator's seat
only.
4.
When using on slopes, one stabilizer may be lower
than the other. Use extreme care duhng excavation as
risk of tip-over will increase,
5. When digging on a hillside, always dump the bucket on
the uphill side of excavation.
6. To reduce the risk of tip-over on a slope, place the
spoil to the high side of the excavation.
7. Do not dig under the stabilizer or tractor, especially in
soft or sandy conditions. Take extra precaution in wet
or thawing ground.
Under these conditions the ground can become
unstable and may collapse under the weight of the
machine and may cause the unit to tip over.
8. Never operate the machine or any equipment while
under the Influence of alcohol or other drugs, or while
fatigued,
9. When leaving the machine unattended, be sure to
lower the backhoe to the ground. Set the parking
brake,
then shut the engine off and remove the key.
SAFETY
Tragic accidents can occur if the operator is not alert to
the presence of children. Children are generally attracted
to machines and the work being done. Never assume
children will remain where you last saw them.
1.
Keep children out of the operating area and under the
watchful eye of another responsible adult.
2.
Be alert and turn the machine off if children enter the
work area.
3. Before and when backing, look behind and down for
small children.
4.
Never carry children while operating the machine.
They may fall off and be seriously injured or interfere
with safe operation of the machine,
5. Never allow children to play on the machine or
attachment even when turned off,
6. Never allow children to operate the machine even
under adult supervision.
7. Use extra care when approaching blind corners,
shrubs, trees, or other olsstructions that might hide
children from sight.
DRIVING
1.
Raise and center the boom, close the dipperstick, curl
the bucket and engage the boom and swing locks
2.
Check the local codes or regulations that may apply to

A-2 SAFE OPERATION
SERVICING
1.
Before disconnecting hydraulic lines, relieve all
hydraulic pressure by moving the controls.
2.
Always use personal protection devices such as safety
goggles and gloves when servicing or repairing the
machine.
3. Lower the backhoe to the ground and shut the engine
off before servicing.
4.
When servicing or repairing pins in cylinder ends,
bucket, etc., always use a brass drift and hammer.
Failure to do so could result in injury from flying metal
fragments.
5. To avoid serious personal injury, keep clear of working
area of the backhoe.
6. When servicing or checking underneath, do not get
under the machine while it is being held with only the
bucket, backhoe or stabilizers. Securely support with
jackstands.
7. For your safety, do not work under any hydraulically
supported machine elements. They can settle,
suddenly leak down, or be accidentally lowered.
8. Escaping hydraulic fluid under pressure can have
sufficient force to penetrate the
personal injury. Before applying pressure to the

9. Do not tamper with any backhoe control valve relief
pressure setting. The relief valve pressure is preset at
the factory. Changing the setting can cause
overloading of the backhoe and the tractor, and
serious personal injury or death may result.

Do not modify the backhoe for any reason. Modifying
the backhoe can cause an unstable condition of the
tractor / loader / backhoe combination and serious
personal injury or death may result.
