J. Secure hydraulic hoses to tractor to prevent
interference. It is recommended that hoses be rout-
ed under tractor operator’s platform.
K. Extend and retract both sets of cylinders
beginning with short strokes. Gradually increase the
length of stroke until cylinders “bottom out” in each
direction. Hold valve open with cylinders “bottomed
out” for 3-5 seconds. This will purge air from
hydraulic components.
NOTE
When valve control is held open, a squealing noise
will be heard when cylinders ”bottom out” and
hydraulic oil passes through relief valve. This may
cause overheating if valve control is held open
longer than 5 seconds.
Make certain optional control valve operates as
shown on decal . If valve operation is incorrect, see
plumbing diagrams for correct connections.
