SAFETY RULES
The safe operation of machinery is a big concern to farmers and manufacturers. You Markers have
been designed with many built-in safety features. However, no one should operate the Drill or Mark-
ers before carefully reading this Owner’s Manual.
1.
NEVER permit anyone near machinery while in operation.
2.
Excessive marker folding speed can cause marker damage.
3.
NEVER allow anyone to be near the drill when cycling the markers.
4.
Reduce speed of the tractor when transporting over uneven or rough terrain. Avoid all chuck
holes and washboard areas in roads.
5.
Reduce speed of the tractor when transporting over hills or steep slopes.
6.
DO NOT lubricate, adjust or repair the drill while it is in operation.
7.
When in transport, use accessory lights and devices for adequate warning to operators of other
vehicles and use safety hitch chain. Comply with all Federal, State and Local laws when trav-
eling on public roads.
8.
Use "Slow Moving Vehicle" emblem for warning vehicles approaching from the rear.
9.
DO NOT permit smoking, sparks, or an open flame where combustible lubricants or liquids are
being used.
10.
CAUTION!
Escaping fluid under pressure can have sufficient force to penetrate
the skin. Check all hydraulic lines and hoses BEFORE applying pressure. Fluid escaping from
a very small hole can be almost invisible. Use paper or cardboard, NOT BODY PARTS, to
check for suspected leaks. If injured, seek medical assistance from a doctor that is familiar with
this type of injury. Foreign fluids in the tissue must be surgically removed within a few hours
or gangrene will result.
11. DO NOT allow anyone to operate the Drill who has not been properly trained in its safe opera-
tion.
