16000 OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES
CONTROLS IDENTIFICATION AND
FUNCTION
A – Engine Controls
See Figure 3-5 for engine controls.
A1. Engine Ignition Switch
Insert key.
Turn CLOCKWISE to RUN position to activate the crane’s
electric circuits.
Turn fully CLOCKWISE to START engine. RELEASE to
RUN position as soon as engine starts.
Rotate COUNTERCLOCKWISE to STOP engine and turn off
crane’s electric system.
NOTE Engine diagnostic faults appear on the engine
screen (see Main display in this section) when the
ignition is in the run position. The faults must go
away when the engine is started. See engine
manufacturer’s operating instructions manual for
engine diagnostic information.
A2. Engine Emergency Stop Switch
Push knob DOWN to STOP engine only in an emergency —
for example, if a crane function does not stop when control
handle is released to off (center position) or any other
uncontrolled motion of a crane function is observed.
Beware — when knob is pushed down, engine stops, brakes
apply, and any functions being operated come to an
abrupt stop.
NOTE The knob must be pulled up before the engine can
be restarted.
If the emergency stop switch has been activated,
test all disk brakes for proper operation before
putting the crane back in service. See Section 2 of
Service Manual for procedure.
Use engine ignition switch (A1) to stop engine for
normal operating conditions.
A3. Engine Hand Throttle
Pull handle BACK to INCREASE engine speed.
Push handle FORWARD to DECREASE engine speed.
NOTE: The selected engine speed is maintained when the
handle is released.
The speed of the crane functions depends on
engine speed and on how far the control handles
are moved in either direction from off.
Engine speed must be fast enough to provide
sufficient power for the work being done. Engine
can stall under load if engine speed is too slow.
A4. Engine Foot Throttle
PRESS foot throttle to INCREASE engine speed above the
hand throttle setting.
RELEASE foot throttle to DECREASE engine speed to idle
or to the hand throttle setting.
NOTE: When the engine speed switch on either remote
control — setup or MAX-ER
®
— is in the high
speed position, you will not be able to decrease
engine speed below approximately 1,500 RPM
with the throttle controls in the cab.
A5. Engine Clutch Lever
Pull clutch lever OUT and push DOWN to DISENGAGE the
clutch.
Pull clutch lever UP and push IN to ENGAGE the clutch.
A6. Battery Disconnect Switch
Turn handle CLOCKWISE to CONNECT battery circuit.
Turn handle COUNTERCLOCKWISE to DISCONNECT
battery circuit for the following reasons:
• When servicing crane’s electrical control system
• If desired, to prevent batteries from discharging when
the crane is stored for extended periods of time
• If desired, to prevent the crane from being started by
unauthorized personnel
NOTE: The handle can be removed from the disconnect
position to keep unauthorized personnel from
connecting the battery and starting the crane.
WARNING
Unauthorized Startup!
Always STOP engine and remove key before leaving the
crane unattended. This practice will prevent unauthorized
personnel from operating the crane.
CAUTION
Engine Damage!
To avoid possible engine fault codes and undesirable
operation, make sure engine ignition switch has been off
five minutes before disconnecting batteries.
Do not rely on this switch to protect crane’s electronic
systems when welding. Disconnect battery cables at
batteries before welding.
