EQUIPMENT SAFETY GUIDELINES
Safety of the operator is one of the main concerns in designing and developing a new piece of
equipment. Designers and manufactures build in as many safety features as possible. However,
every year many accidents occur which could have been avoided by a few seconds of thought and
a more careful approach to handling equipment. You, the operator, can avoid many accidents by
observing the following precautions in this section. To avoid personal injury, study the following
precautions and insist those working with you, or for you, follow them.
In order to provide a better view, certain photographs or illustrations in this manual may show an
assembly with a safety shield removed. However, equipment should never be operated in this
condition. Keep all shields in place. If shield removal becomes necessary for repairs, replace the
shield prior to use.
Replace any CAUTION, WARNING, DANGER or instruction safety decal that is not readable or
is missing. Location of such decals are indicated in this manual.
Do not attempt to operate this equipment under the influence of drugs or alcohol.
Review the safety instructions with all users annually.
This equipment is dangerous to children and persons unfamiliar with its operation. The operator
should be a responsible adult familiar with farm machinery and trained in this equipment’s operations.
Do not allow persons to operate or assemble this unit until they have read this manual and have
developed a thorough understanding of the safety precautions and of how it works.
To prevent injury or death, use a tractor equipped with a Roll Over Protective System (ROPS). Do
not paint over, remove or deface any safety signs or warning decals on your equipment. Observe all
safety signs and practice the instructions on them.
Never exceed the limits of a piece of machinery. in its ability to do a job, or to do so safely, is in
question - DON’T TRY IT.
LIGHTING AND MARKING
It is the responsibility of the customer to know the lighting and marking requirements of the local
highway authorities and to install and maintain the equipment to provide compliance with the
regulations. Add extra lights when transporting at night or during periods of limited visibility.

posts. Use a volt-meter or hydrometer.
Do not charge a frozen battery; it may explode. Warm battery to
16C (60F)
AVOID HIGH-PRESSURE FLUIDS
Escaping fluid under pressure can penetrate t he skin causing seriou s
injury or death.
Avoid the hazard relieving pressure before disconnecting hydraulic
or other lines. Tighten all connections before applying pressure.
Search for leaks with a piece of cardboard. Protect hands and body
from high pressure fluids.
If an accident occurs, see a doctor immediately. Any fluid injected
into the skin must be surgically removed within a few hours or
gangrene may result. Doctors unfamiliar with this type of injury
should reference a knowledgeable medical source.
