TB60/66J – 0084030EE 5
This aerial work platform is manufactured with safety
devices, placards, and decals to reduce the likelihood of
an accident. For the safety of all personnel, do not dis-
able, modify or ignore any safety device. Safety devices
are included in the daily prestart inspection.
A Warning
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury can result from such accidents. Do not alter,
disable, or override any safety device.
If any safety devices are defective, remove the aerial
platform from service until qualified maintenance person-
nel can make repairs.
Emergency Stop Controls
There is an emergency stop control at the lower and
upper controls.
At the lower controls, the emergency stop is a two-posi-
tion push button (refer to Figure 4.). Push the emer-
gency stop button in to disconnect power to all control
circuits. Pull the button out to restore power.
Figure 4.1 – Lower Controls
Note
The lower controls override the upper controls. If the
upper control emergency stop button is engaged, the
lower controls can still be used to operate the aerial
platform.
At the upper controls, the emergency stop is a two-posi-
tion push button (refer to Figure 4.2).
Figure 4.2 – Upper Controls
Push the emergency stop button in to disconnect power
to the upper control circuits. Pull the button out to restore
power.
Emergency Power System
The emergency power system includes a back-up
pump, motor, and battery. Use this system to operate
the boom and turntable functions to lower the platform
if the main power system fails due to engine or pump
failure. Hold the engine/emergency power switch (refer
to Figure 4. and 4.2) down to activate the emergency
power system.
The length of time the pump can be operated depends
on the capacity of the battery.
Emergency Lowering Knob
The emergency lowering knob may be used to lower
the booms if the engine will not start and the emergency
power system will not work. The knob is on the base
end of the main boom lift cylinder (refer to Figure 4.3)
under the left side of the turntable.
