Operating and Repair
Operating and Repair
5
Most accidents are the result of negligence and
carelessness, usually caused by failure of the operator to follow simple but necessary safety
precautions.Thefollowingsafety precautions are
suggested to help prevent such accidents. The
safe operation of any machinery is a big concern
to consumers and manufactures.Your PFH Flat
Fold Maker has been designed with many built-in
safety features. However, no one should operate
this product before carefully reading this Operators Manual.
General Operation & Repair
Neverallow the PFH 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 givenin this manual prior to moving the
unit.
1. Makesuresafetyrules areunderstoodbefore
operating machinery or tractor.
2. Never permit any persons other than the op-
erator to ride on the tractor.
3. Never permit any persons to ride on or stand
near the drill while it is in operation.
4. Regulate your speed to the field conditions,
maintaining complete control at all times.
5. After repairing or adjusting, make sure all
tools and parts are removed from the implement before attempting to operate it.
6. Do not grease or oil machine while it is in op-
eration.
7. Loosefitting clothing should not be worn as it
may catch in moving parts.
8. Never dismount from a moving tractor.
9. Do not leave the tractor or the implement un-
attended with the engine running.
12. 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 hydraulicfluid,
see a doctor at once!
13. Use a piece of cardboard or wood to detect
leaks of hydraulic oil under pressure.
14. Besureto relieveallhydraulic pressure before
disconnecting 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. Alwaysmake sure flashing safety lights,
“SlowMoving 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. Usewarning flags or approvedwarning lights
at night and during other periods of poor visibility. Do your best to prevent highway accidents.
4/9/2004
10. Do not stand between the tractor and the implement during hitching.
11. Detach and store implements in an area
where children normally do not play. Stabilize
implements by using suitable supports and
block wheels.

NOTE:Check the hydraulicfluid in the tractor reservoir and fill it to the proper level. Add fluid to the
system as needed. A low reservoir may draw air
back into the system causing jerky or uneven
movement. The fluid capacity of the markers is
.75 gallons.
12. With the first section in the lowered position,
connect the hoses to the tractor and cycle
each cylinder 3 or 4 times. Both arms should
moveto the vertical position on the first move
and then they should lower and raise alternately as the hydraulic lever is operated.

CAUTION
Escaping Fluid under pressure can have sufficient
force to penetrate the skin. Check all hydraulic lines
and hoses before applying pressure. Fluid escaping
froma very small hole can be almost invisible.Use paper or cardboard,not body parts, to check for suspected leaks. If injured, seek medical assistance form a
doctor who is familiar with this type of injury. Foreign
fluids in the tissue must be surgically removedwithin a
few hours or gangrene will result.

Maintenance and Lubrication
Maintenance
Proper servicing and adjustment is the key to the long
life of any farm implement. With careful and systematic
inspection, you can avoid costly maintenance, downtime and repair.
Breakaway Protection
The marker arm is attached to the marker body with a
5/16" breakaway bolt. If excessive force is put on the
markerduringoperation,the bolt will break, allowing the
marker arm to swing away rather than cause damage to
the marker.
NOTE: The breakaway bolt is a 5/16"-18 x 1 1/2" long
grade5 (G.P.# 802-012C). It isidentified as a grade5 by
having three marks on the head. If it breaks, it must be
replacedby an equivalentgrade5bolt to preventmarker
damage.
Lubrication
Marker Transporting
Always transport the marker with it folded in the flat fold
position.
