Look for Safety Symbol
The SAFETY ALERT SYMBOL indicates there is
a potential hazard to personal safety involved and
extra safety precaution must be taken. When you
see this symbol, be alert and carefully read the
message that follows it. In addition to design and
configuration of equipment, hazard control and
accident prevention are dependent upon the
awareness, concern, prudence and proper train-
ing of personnel involved in the operation,
transport, maintenance and storage of
equipment.
Be Aware of Signal Words
Signal words designate a degree or level of haz-
ard seriousness.
DANGER indicates an imminently hazardous sit-
uation which, if not avoided, will result in death or
serious injury. This signal word is limited to the
most extreme situations, typically for machine
components that, for functional purposes, cannot
be guarded.
WARNING indicates a potentially hazardous situ-
ation which, if not avoided, could result in death or
serious injury, and includes hazards that are ex-
posed when guards are removed. It may also be
used to alert against unsafe practices.
CAUTION indicates a potentially hazardous situ-
ation which, if not avoided, may result in minor or
moderate injury. It may also be used to alert
against unsafe practices.

Keep Riders Off Machinery
Riders obstruct the operator’s view. Riders could
be struck by foreign objects or thrown from the
machine.
Never allow children to operate equipment.
Keep all bystanders away from machine
during operation.
Shutdown and Storage
Lower drill, put tractor in park, turn off engine,
and remove the key.
Secure drill using blocks and supports pro-
vided.
Detach and store drill in an area where chil-
dren normally do not play.
Use Safety Lights and Devices
Slow-moving tractors and towed implements can
create a hazard when driven on public roads.
They are difficult to see, especially at night.
Use flashing warning lights and turn signals
whenever driving on public roads.
Use lights and devices provided with imple-
ment.

Important Safety Information
Transport Machinery Safely
Maximum transport speed for implement is 20
mph. Some rough terrains require a slower
speed. Sudden braking can cause a towed load to
swerve and upset.
Do not exceed 20 mph. Never travel at a
speed which does not allow adequate control
of steering and stopping. Reduce speed if
towed load is not equipped with brakes.
Comply with state and local laws.
Do not tow an implement that, when fully
loaded, weighs more than 1.5 times the weight
of towing vehicle.
Carry reflectors or flags to mark drill in case of
breakdown on the road.
Keep clear of overhead power lines and other
obstructions when transporting.
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the
skin, causing serious injury.
Avoid the hazard by relieving pressure before
disconnecting hydraulic lines.
Use a piece of paper or cardboard, NOT
BODY PARTS, to check for suspected leaks.
Wear protective gloves and safety glasses or
goggles when working with hydraulic systems.
If an accident occurs, see a doctor immedi-
ately. Any fluid injected into the skin must be
surgically removed within a few hours or gan-
grene may result.

Understand procedure before doing work. Use
proper tools and equipment. Refer to this man-
ual for additional information.
Work in a clean, dry area.
Lower the drill, put tractor in park, turn off
engine, and remove key before performing
maintenance.
Make sure all moving parts have stopped and
all system pressure is relieved.
Allow drill to cool completely.
Disconnect battery ground cable (-) before
servicing or adjusting electrical systems or
before welding on drill.
Inspect all parts. Make sure parts are in good
condition and installed properly.
Remove buildup of grease, oil or debris.
Remove all tools and unused parts from drill
before operation.
Prepare for Emergencies
Be prepared if a fire starts.
Keep a first aid kit and fire extinguisher handy.
Keep emergency numbers for doctor, ambu-
lance, hospital and fire department near
phone.
Wear Protective Equipment
Wear protective clothing and equipment.
Wear clothing and equipment appropriate for
the job. Avoid loose-fitting clothing.
Because prolonged exposure to loud noise
can cause hearing impairment or hearing loss,
wear suitable hearing protection such as ear-
muffs or earplugs.
Because operating equipment safely requires
your full attention, avoid wearing radio head-
phones while operating machinery.

Important Safety Information
Handle Chemicals Properly
Agricultural chemicals can be dangerous. Im-
proper use can seriously injure persons, animals,
plants, soil and property.
Read and follow chemical manufacturer’s
instructions.
Wear protective clothing.
Handle all chemicals with care.
Avoid inhaling smoke from any type of chemi-
cal fire.
Store or dispose of unused chemicals as
specified by chemical manufacturer.
Use A Safety Chain
Use a safety chain to help control drawn
machinery should it separate from tractor
drawbar.
Use a chain with a strength rating equal to or
greater than the gross weight of towed
machinery.
Attach chain to tractor drawbar support or
other specified anchor location. Allow only
enough slack in chain to permit turning.
Replace chain if any links or end fittings are
broken, stretched or damaged.
Do not use safety chain for towing.
Tire Safety
Tire changing can be dangerous and should be
performed by trained personnel using correct
tools and equipment.
When inflating tires, use a clip-on chuck and
extension hose long enough for you to stand
to one side–not in front of or over tire assem-
bly. Use a safety cage if available.
When removing and installing wheels, use
wheel-handling equipment adequate for
weight involved.
