EMERGENCY LOWERING VALVE ON JIB
1.
EMERGENCY LOWERING VALVE ON BOOM -
Located at the base on the boom cylinder, this valve
allows boom lowering in the event of an emergency or
an electrical system failure. Turning the valve knob
counterclockwise allows the boom to gradually lower.
Valve MUST be fully closed (clockwise) to restore normal
operation.
2.
EMERGENCY LOWERING VALVE ON JIB -
Located at the base on the jib cylinder, this valve allows
boom lowering in the event of an emergency or an
electrical system failure. Turning the valve knob
counterclockwise allows the jib to gradually lower. Valve
MUST be fully closed (clockwise) to restore normal
operation.

DRIVE RELIEF VALVE WITH OVERRIDE STEM.
The relief override stems, located on the top and bottom
of the Drive Pump, are used to override the drive relief
valves allowing the machine to be loaded or unloaded
from a trailer using a winch line. To override the drive
relief valve the procedure below MUST be followed:
DANGER
DO NOT attempt to override the relief valves without the
wheels chocked.
Step 1. Place the machine on a flat level surface and
chock the wheels to prevent from rolling.
Step 2. Loosen the retaining nut on the relief valve
override stem. Screw in the override stem
(clockwise) until it stops. Repeat this step for
both relief valves.
Step 3. Release the parking brake (see Brake Manifold
in this section). The machine is now ready to be
loaded or unloaded using a winch line.
