Assembly Section 2-24
ASSEMBLY
FINAL PREPARATION FOR OPERATION
Place operators safety and operation decals on the steering column and side
counsel where they are clearly visible to the operator. These decals should be
understood by each operator of the machine in conjunction with the safety and
operation section of this book. The decals are to be maintaned in good condition as
a reminder to the operator, and should be replaced if damaged.
Finally, all bosses, pins and pivot points will need to be greased as instructed in
the maintenance section of this manual. The hydraulic reservoir can also be filled
with the recommended fluid (see maintenance section) and the filter installed in the
top of the tank. Double check all fittings and fasteners BEFORE starting tractor.
Also secure any loose hoses together with zip ties and wrap with split hoses where
friction may occur on the hoses.
BEFORE starting or operating the tractor you must read and
understand the safety and operation sections of this manual
completely.
BE SURE THE BALL VALVES ARE OPEN! Start tractor and allow instruments
to stabilize. Using a piece of paper or cardboard as noted in the safety and
maintenance sections, check all fittings and connections for hydraulic leaks.
If a leak is found, you must shut down the tractor, set the cutter on the ground.
Before attempting to fix the leak, you must actuate the lift valve handles several
times to relieve any pressure in the lines.
Before operating the mower, the cutter head and boom should be slowly moved
throughout the full range of motion. Watch for any condition that would cause pinching
or excess stress on the hoses. The steering and front axle travel should also be
carefully moved through their full range of motion. If any condition occurs in which
the hoses contact the tires, the steering and / or front axle travel may need to be
limited as described in the tractor operators manual. This should also be done if the
tires rub, or are extremely close to any other part of the mower such as the hydraulic
tank or draft beam. This may include adding shims, or adjusting stop bolts in the
tractor front to solve the problem. While checking motion, you should also check
that the control circuits are connected according to the operators decal for the valve
handles.
MOWER TESTING
Take the tractor to a place free of loose objects on the ground. Operate the
cylinders through their full range of motion again, to clear the lines of air. Follow the
instructions in the operation section to operate the mower. Vibration of the mower
should be minimal at all times. After a 5 minute test run, the knife bolts should be
retorqued and once again after the first few hours of operation.
If any parts of this assembly section, or any other section of this
manual are not clearly understood you must contact your dealer or the
address on the front of this manual for assistance!
