Safety valves
The safety valves are intended to prevent the front equipment from dropping down in the event of a breakage or burst
of a hose in the hydraulic lines of boom and arm. The safety valves keep the front equipment in the position at the
time of breakage, and thus allow the operator to slowly lower the attachment to the ground using the left and right
control levers.
Moreover, the safety valves allow to keep the front equipment in the selected operating position reducing the leakages
that occur in the neutral position of the boom spool and the arm spool in the main control valve.
NOTICE: prior to starting any handling of suspended loads check that the valves do not show clear evidence of dam-
ages or abnormal noises. In the event abnormal conditions are found, contact the CASE CONSTRUCTION. dealer.
NOTICE: the pressure setting of the safety valves must be checked every 6 months. Consult the CASE CONSTRUC-
TION dealer.
