Emergency Operations
Part ll - Hydraulic Line Failure
In case of hydraulic line failure, there are step-by-step procedures available
to assist you in safely retracting and then lowering the boom. Read Part II
from start to finish before performing any of these procedures so you fully
understand the process and the danger involved. If you are unsure about
any part of these procedures contact your local Sky Trak Distributor or the
JLG Service Department.
Every attempt should be made to repair the hydraulic line failure and to
retract and then lower the boom in its normal fashion. We realize this is not
always possible. Step-by-step procedures are also available when the boom
must be retracted and lowered immediately and replacement parts are not
available. Only resort to Steps 3 & 4 when absolutely necessary.
IMPORTANT! Be aware that the boom must first be retracted and then
lowered to avoid vehicle tipover.
In any case of hydraulic line failure, it is critical to correctly identify which
hydraulic line has failed. Identify the hydraulic line that has failed and use
the table on page 99 to determine which Step to follow to retract and lower
the boom.
