OPERATING CONTROLS - AERIAL LIFT NBT40-1 SERIES OPERATOR MANUAL
RCL Check
Perform the following checks to verify proper RCL operation.
• Check that the display of the main boom length agrees
with the actual boom length.
• Check that the display of the main boom angle agrees
with the actual boom angles.
• Check that the display of the platform reach of the
equipment agrees with the actual reach.
Radio Remote/Aerial Power Switch
Operation of the aerial lift is controlled by the radio remote
controller, (Reference Radio Remote/Aerial Power Switch (if
equipped), page 4-11
). To operate the controller, the remote/
aerial power switch (19) located on the cab overhead console
(Figure 4-3) must be activated. The crane
control power
switch (20) must be turned OFF. The Operator Cab/Ground
Control Ignition Switch (13) and chassis igniton must all be
OFF.
NOTE: When the radio remote control is activated, all
crane ground controls will be deactivated.
Reach Diagram
The Load Chart/Reach Diagram is located in a pocket in the
ground station control cab. A reach diagram decal is located
on the aerial work platform. The Reach Diagram contains
platform reach, platform height, and important information
regarding allowable platform operating configurations.
Hydraulic Tool Circuit - Option
Hydraulic Intensifier Valve
The hydraulic intensifier valve is compatible with high
pressure hydraulic equipment to meet most tooling
requirements. It provides a single/double acting 3-way
control (Advance, Neutral, and Retract) valve direct from
high pressure source and allows return oil to bypass the
hydraulic intensifier and return to tank line. Reference
9828221048 Valve Intensifier manual.
Hose Installation
1. Ensure power is OFF and oil has cooled.
2. Ensure valve is in Retract position.
3. Connect hose to hydraulic supply.
4. Connect hose to Pressure Port on valve, then connect to
Port on tool.
Disconnecting hose
1. Turn Off hydraulic source
2. Ensure valve handle is in Retract position and oil has
cooled before disconnecting.
3. Disconnect hose from valve before disconnecting tool.
4. Disconnect pressure hose from pressure “P” port on
valve.
5. Disconnect Return hose from return “T” port on valve.
6. Disconnect hose from Return port (Tank) on source.
7. Install dust caps on all connectors to prevent dirt and
contaminants from entering hydraulic system.
Operation
1. Ensure valve is in Retract position before initiating
hydraulic power source.
2. Activate valve by moving handle to left in the Advance
position. The tool operation will begin immediately.
NOTE: Moving handle to Hold (center) position will stop
tool action allowing for confirmation and
repositioning as needed. When relief valve popping
occurs, desired pressure has been achieved and
operation should be complete. Repeat as
necessary.
NOTE: Holding valve handle in Advance position after
relief valve has popped will cause unnecessary
wear on relief valve and pump assembly.
3. Move valve to Retract and allow tool to return fully.
4. Valve should be in Retract position when not in use.
DANGER
The RCL aids the operator when properly programmed
with the proper equipment configuration. To prevent injury
or death to personnel, be sure the RCL is programmed
before equipment operation.
DANGER
A deviation between displayed and actual values
indicates a malfunction and a RCL service representative
shall be called for repair and/or recalibration of RCL
system.
DANGER
Failure to comply with these warnings may result in
severe bodily injury. Do not connect or disconnect tool,
hoses, or fittings while tool is running, hot, or under
pressure. Serious injury or burns could result.
