WARNING
·
The LHS hydraulic system operates at oil pressures up to 1,725 psi (11 894 kPa).
Never disconnect any hydraulic line or fitting without first dropping pressure to
zero. Failure to comply may result in serious injury or death to personnel.
·
Fuel and oil are slippery and can cause falls. To avoid injury, wipe up spilled fuel or
oil with rags.
·
Do not get under LHS when disconnecting or connecting connectors or hoses. A
hydraulic malfunction could cause LHS to lower causing serious injury.
NOTE
Use drain pan to catch leaking hydraulic oil.
Step 2. Check for fluid leaks from LH and RH hook arm manifold, port VB with main frame up and
hook arm loaded.
Disconnect and plug hoses 2881 and 2892 from hook arm manifold, port VB. Let
excess oil in manifold drain. If hydraulic fluid continues to drain from LH or RH
hook arm manifold at port VB, replace load control valve at leaking port VB
(Para 5-36).
