Maintenance 10
• NEVER GO UNDERNEATH EQUIPMENT.
Never place any part of the body underneath
equipment or between moveable parts even
when the engine has been turned off. Hydraulic
system leak down, hydraulic system failures,
mechanical failures, or movement of control
levers can cause equipment to drop or rotate
unexpectedly and cause severe injury or
death.
• Service work does not require going under-
neath.
• Read Manual for service instructions or have
service performed by a qualified dealer.
The information in this section is written for
operators who possess basic mechanical skills.
If you need help, your dealer has trained ser-
vice technicians available. For your protection,
read and follow the safety information in this
manual.
• Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
• Before dismounting power unit or performing
any service or maintenance, follow these steps:
disengage power to equipment, lower the 3
point hitch and all raised components to the
ground, operate valve levers to release any
hydraulic pressure, set parking brake, stop
engine, remove key, and unfasten seat belt.
• Always wear relatively tight and belted cloth-
ing to avoid entanglement in moving parts.
Wear sturdy, rough-soled work shoes and pro-
tective equipment for eyes, hair, hands, hear-
ing, and head.
Gang Assembly for Maintenance
• When performing maintenance or repairs
make sure the equipment is in the lowered
position and both the mainframe and gangs are
properly blocked and secured to prevent rolling.
Failure to do so can cause serious injury or
death.
When gang component replacement is required,
carefully observe all safety issues. Place unit
on level ground prior to gang drop. Also make
sure that gangs are blocked to keep them from
rolling in either direction. After unit is lowered to
ground and gangs are secure, loosen nuts on
all hex bolts holding hangers to main frame
(item 7). Observe the sequence and location of
each gang component and refer to the gang
diagram on Figure 1 for removal and replace-
ment of the desired component. After replace-
ment is completed reinstall gang parts in proper
order as shown on gang diagram on Figure 1.
Make sure that the gang nut on the gang axle
is properly tightened after replacements are
made. Refer to “ Bolt Tightening Torque Chart”
on page 15 for proper torque.
Storage
When storing your disc harrow make sure the
unit is placed on level ground and that the
gangs are properly chocked by bracing with
6”x6” blocks on the front and rear side of one
complete gang assembly. See the diagram
below.
