Section 1 Safety Rules

Section 1 Safety Rules

Most accidents are the result of negligence and care­lessness, usually caused by failure of the operator to
follow simple but necessary safety precautions. The fol
lowing safety precautions are suggested to help prevent
such accidents. The safe operation of any machinery is
a big concern to consumers and manufacturers. Your All
Seeds Hitch Flat Fold Marker has been designed with
many built-in safety features. However, no one should
operate this product before carefully reading this Oper
ators Manual.

!

General Operation & Repair

1. Never allow the Flat Fold Marker to be operated by any­one who is unfamiliar with the operation of all functions
of the unit. All operators should read and thoroughly un­derstand the instructions given in this manual prior to
moving the unit.

2. Make sure safety rules are understood before operating
machinery or tractor.

3. Never permit any persons other than the operator to ride
on the tractor.

4. Never permit any persons to stand near the Flat Fold
Marker while it is in operation.

5. Regulate your speed to the field conditions, maintaining
complete control at all times.

6. After repairing or adjusting, make sure all tools and
parts are removed from the implement before attempting
to operate it.

7. Do not grease or oil machine while it is in operation.

8. Loose fitting clothing should not be worn as it may catch
in moving parts.

9. Never dismount from a moving tractor.

10. Do not leave the tractor or the implement unattended
with the engine running.

11. Do not stand between the tractor and the implement dur-

ing hitching.

12. Detach and store implements in an area where children

-

-

normally do not play. Stabilize implements by using suit
able supports and block wheels.

13. If a hydraulic leak develops, correct it immediately. Es­caping hydraulic oil can have extremely high pressure. A
stream of high pressure oil may easily penetrate the skin
as with modern needle-less vaccination equipment - but
with the exception that hydraulic fluid may cause blood
poisoning. It is imperative that the connections are tight
and that all lines and pipes are in good condition. If an
injury is caused by the escaping hydraulic fluid, see doc­tor at once!

14. Use a piece of cardboard or wood to detect leaks of hy­draulic oil under pressure.

15. Be sure to relieve all hydraulic pressure before disconnec­tion any lines or pipes between the implement and the trac­tor hydraulic system. Keep all guards and shields in place.

Transporting

1. Use good judgement when transporting tractor and im­plements on the highway. Always maintain complete con­trol of the machine.

2. Limit transport speed to 20 mph. Transport only with a
farm tractor of sufficient size and horse power.

3. Always make sure flashing safety lights, “Slow Moving
Vehicle” emblem, and reflectors are in place and visible
prior to transporting the machine on public roads.

4. Know your state and local laws concerning highway
safety and regulations. Comply with these laws when
transporting machinery.

5. Use warning flags or approved warning lights at night
and during other periods of poor visibility. Do your best
to prevent highway accidents
