the ground under gravity indicates that the
accumulator functions normally.

to lower or is held half way, the pressure in
the hydraulic circuit accumulator may have
dropped already.
Consult Sany distributor for such inspec-
tion.
7. After checking through the a.m. steps,
place the hydraulic lockout control to LOCK
