Important Safety Information
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 training 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 hazard
seriousness.
DANGER indicates an imminently hazardous situation
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 situation
which, if not avoided, could result in death or serious
injury, and includes hazards that are exposed when
guards are removed. It may also be used to alert against
unsafe practices.
CAUTION indicates a potentially hazardous situation
which, if not avoided, may result in minor or moderate
injury. It may also be used to alert against unsafe
practices.
Use Adequate Lifting Means
The frame sections and gangs of this machine are
extremely heavy. If using multiple lifters, make sure each
is rated for at least its share of the load.
Prepare for Emergencies
Be prepared if a fire starts
Keep a first aid kit and fire extinguisher handy.
Keep emergency numbers for doctor, ambulance, hospital
and fire department near phone.

Description of Unit
The MC5109-5315 Max-Chisel is a one or three-section
“vertical” tillage tool. Working width ranges from 11’ 6” to
19. The implement is designed to cut, size and bury
residue. It can work up to 11” deep, the blades will
dislodge rootballs while mixing and incorporating residue
in the top 4-5” of soil chopping in to accelerate the
decaying process, leaving the field smooth enough for
“one pass” finishing in Spring. For optimum leveling of
your machine, it should be equipped with either a
Chopper Reel or Buster Bar attachment.

installed. The following procedure is for any hoses
that have not been connected, or have needed repair.
41. Inspect all components for damage or contamination
during shipping.
42. Lubricate o-ring and threads on fitting.
43. Thread straight (non-adjustable stud) fittings into
ports finger tight.
44. Thread elbow (adjustable stud) fitting into side
port of depth stop valve . Thread straight (non-
adjustable stud) fittings into front port of depth
control valve .
Do not over tighten as this could cause damage to
valves. Tighten as shown, See “Hydraulic
Connectors and Torque” on page 22 or proper
torque value.
45. Route hoses as shown in layout section in Appendix.
46. When the JIC hoses are routed, follow the following
procedure for hooking up and tightening.
a. Inspect for possible contamination or damage from
shipping or handling. Sealing surface should be
smooth. Annular tool marks of (100uin) concentric
with thread permissible.
b. Lubricate the threads and the entire surface of the
cone with hydraulic fluid or a light lubricant.
c. Align mating components for hand connection and
turn flare nut until sealing surfaces make full contact.
d. Torque nut to the values shown in “Torque Value
Chart” page 23. If a wrench pad is provided next to
nut, place a second wrench on pad to prevent flare
from rotating while being torqued.
e. When torquing nut onto a straight flared fitting, it may
be necessary to also place a wrench on the flared fit-
ting wrench pad to prevent it from turning during
assembly.
47. Alternate Assembly Method for JIC.
a. If torqued method not possible, then proceed to
steps b-e.
b. Lightly wrench tighten the nut until there is firm resis-
tance.
c. Place a wrench on wrench pad next to nut as near
the 6 0’clock position as possible.
d. Place second wrench on nut as near the 3 o’clock
position as possible.
e. Turn nut clockwise to no less than the 4 o’clock posi-
tion and no more than the 6 o’clock position.
Required rotation generally decreases as size
increases.

Hose Handles
Refer to Figure 12
51. To distinguish hoses on the same hydraulic circuit,
refer to hose handles. The hose under an extended-
cylinder symbol feeds a cylinder base end. The hose
under a retracted-cylinder symbol feeds a cylinder
rod end.
52. Once all hoses are tightened, hook hoses to tractor

Purging Hydraulic System
Refer to Figure 13
53. Charge the lift system first. Extend the lift cylinders (black handles) until the center section is fully raised.
Remove the cylinder transport locks and install in storage position. Raise and lower the lift system several times
to purge air from system. Watch for leaks and re-tighten fittings if necessary.
54. The gang frame system (red handles), will need purged. If your machine is a 3 section model the wing gangs
will not start to rise until the center cylinders are fully extended and the master cylinders begin to bypass oil
through the rephasing ports, to the wing cylinders. Continue to pump oil to the gang system until the wing gang
cylinders are also fully extended. At this point, reverse the flow and raise the gangs, retracting all cylinders.
Repeat this procedure several times until all the air is purged out of the system.
55. If your machine is a 3 section model you may now charge the fold system. Before charging the fold cylinders
make sure the rod end of the cylinders are un-pinned and block is under cylinder as shown, so that when the rod
is extended, it will clear the wing fold brackets. Extend the fold cylinders (green ends) completely and then close
them. Extend and retract the cylinders several times to purge air from the system. Now the cylinders may be
extended far enough to be connected to the wing fold brackets. Remove wood block and install the 1 x 338 clevis
pin, 1.5 x 1.0 x.075 machine washer and 316 x 2 cotter pin.
