AUXILIARY HYDRAULIC
CONTROL VALVE
WARNING
To avoid serious injury or death:
• Escaping the hydraulic fluid under pressure can
obtain sufficient force to penetrate skin, which
cause serious personal injury.
Before disconnecting the lines, be sure to
relieve all pressure.
• Before applying the pressure to the hydraulic
system, be sure that all connections are tight,
and that the lines, tubes, and hoses of the
hydraulic system are not damaged.
• Hydraulic fluid escaping from a very small hole
can be almost invisible. Use a piece of
cardboard or wood, rather than hands to search
for suspected leaks.
• If someone gets injured by escaping hydraulic
fluid, see a doctor at once. Serious infection or
allergic reaction will develop if proper medical
treatment is not administered immediately.
1. Valve lock
The control valve is equipped with a feature of the
valve lock.
WARNING
To avoid personal injury or death from crushing:
• Do not utilize the valve lock for machine
maintenance or repair.
• The valve lock is to prevent accidental actuation
when implement is not in use or during
transport.
The control valve is locked in the lock position.
The lock is not intended and will not prevent a leak
down of the implement during the period of storage.
