Load Handling, Emergency Load Lowering
WARNING
When the electronic signal is disrupted, the mast
assembly can ONLY be lowered with the emergency
load lowering valve, located on the main hydraulic
valve. When using the emergency load lowering valve
to lower a load, serious injury can result if anyone is
near or under the load. See Figure 18 and Figure 19.
WARNING
When the electronic signal is disrupted and the mast
assembly is in a raised position, always lower the mast
assembly with the load lowering valve before leaving
the lift truck unattended.
NOTE: The emergency load lowering valve is to be used
ONLY if the electrical signal to the main control valve has
been disrupted and there is a load lifted.
The emergency load lowering valve is located on the front
side of the main control valve. See
Figure 18 and Fig-
ure 19 .
Manual Main Control Valve
To use the emergency load lowering valve, follow these
steps:
1. Remove floor mat and floor plate.
2. Turn the emergency load lowering valve counterclock-
wise. The more opened the valve is, the faster the load is
lowered. See
Figure 18 .
3. When load has been safely lowered, turn the valve
clockwise until it is tight to set the emergency load lowering
valve back into operation mode.
4. Install floor plate and floor mat.
