LOWER BOOM WITH ENGINE STOPPED
(WHEN NOT EQUIPPED WITH BOOM
CYLINDER LOAD LOWERING VALVE)
When an engine stops during operation, the boom cannot
be lowered using the pilot controller because there is no
pilot pressure oil to move the boom valve spool.
CAUTION: Prevent possible injury from
unexpected machine movement. Clear all
persons from the area before lowering the
boom with the engine stopped.
1. Remove the control valve access cover.
