The information in this section is written for operators who possess basic
mechanical skills. If you need help, your dealer has trained service technicians
available. For your protection, read and follow the safety information in this
manual.
WARNING
Keep all persons away from operator control area while performing
adjustments, service, or maintenance.
Before working underneath, disconnect driveline from tractor, lower
wings to ground, raise cutter, and pin transport bar in raised position.
Attach parking jack and lower to ground. Securely block all four corners
of center section and each wing with jack stands. Blocking up prevents
the cutter from dropping due to hydraulic leak down, hydraulic system
failure, or mechanical component failure.
Service and maintenance work not covered in OWNER SERVICE
must be done by a qualified dealership. Special skills, tools, and safety
procedures may be required. Failure to follow these instructions can
result in serious injury or death.
Before servicing, adjusting, repairing or unplugging, stop tractor
engine, place all controls in neutral, set park brake, remove ignition key,
and wait for all moving parts to stop.
Never perform service or maintenance with engine running.
CAUTION

BLOCKING METHOD
To minimize the potential hazards of working underneath the cutter, follow
these procedures:
WARNING
Before performing any service or maintenance, lower equipment to
ground or block securely, turn off engine, remove key, and disconnect
driveline from tractor PTO.
Never go underneath equipment (lowered to the ground or raised)
unless it is properly blocked and secured. 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 sys-
tem failures, mechanical failures, or movement of control levers can
cause equipment to drop or rotate unexpectedly and cause severe injury
or death. Follow Operator's Manual instructions for working underneath
and blocking requirements or have work done by a qualified dealer.
Do not position jackstands under wheels, axles, or wheel supports. Compo-
nents can rotate and cause cutter to fall.
1.
Jackstands with a load rating of 450 kg or more are the only approved
blocking device for this cutter. Install jackstands (shown by Xs in Figure
4) under the cutter before working underneath unit.
2.
Consider the overall stability of the blocked unit. Just placing jackstands
underneath will not ensure your safety.
The working surface must be level and solid to support the weight on the
jackstands. Make sure jackstands are stable, both top and bottom. Make
sure cutter is approximately level.
3.
With full cutter weight lowered onto jackstands, test blocking stability
before working underneath.
4.
If cutter is attached to tractor when blocking, set the brakes, remove key,
and block cutter before working underneath.
5.
Securely block rear tractor wheels, in front and behind.
