SECTION 4 - MACHINE OPERATION
Raising And Lowering The Jib
Raising the jib :
1. Depress footswitch.
2. Pull the jib function control switch toward the
operator to raise the jib within 5 seconds after the
footswitch has been depressed.
3. Adjust the speed movement using the function
speed control.
Lowering the jib :
1. Depress footswitch.
2. Push the jib function control switch away from the
operator to lower the jib within 5 seconds after the
footswitch has been depressed.
3. Adjust the speed movement using the function
speed control.
Slewing The Turntable
To slew :
1. Depress footswitch.
2. Move the turntable slewing control switch to the
right to slew the turntable to the right. Move the
turntable slewing control switch to the left to slew
the turntable to the left. The switch has to be
operated within 5 seconds after the footswitch has
been depressed.
3. Adjust the speed movement using the function
speed control.
Work Platform Functions Combination
A drive movement cannot be combined with a structure
movement.
If a mast or jib raising movement is activated with a
slewing movement, only one function will work and only at
low speed (lower than normal slewing speed) will be
attainable.

MANUAL LOWERING CONTROLS
The manual lowering controls should be used in
emergency situations or mechanical breakdown. The
manual lowering controls provide an auxiliary means of
lowering and raising the platform and slewing the
turntable in the event of primary power loss.

ALARMS
Horn
Horn is activated when the corresponding push button
located on the Platform Control Console is depressed.
Motion Alarm
The machine is fitted with 2 lights (beacons) that come
on as soon as a function is controlled from the platform
control panel or from the ground control panel.
Tilt Light And Alarm
The alarm is triggered by a tilt sensor located on the
right hand side (Toucan 870), left hand side (Toucan
800) of the chassis under the chassis cover. This alarm
is active once the mast (and/or the jib for Toucan 800
manufactured before 2010), has left its lowered
position. It consists of a light on the platform control
panel and an alarm. The alarm and light indicate that
the work platform is at its maximum out of level limit
(refer Table 8.1) and is nearing an unstable position.
Drive function is disabled and the jib, mast and
turntable slewing movements are operable at a
reduced speed.
W h e n t h e t i l t l i g h t o r a l a r m i s a c t i v a t e d , i t i s
recommended to place the machine in the following
configuration :
1. Mast lowered.
2. Jib in line with the chassis length.
3. Jib lowered.
The tilt alarm and light are also operational from the
ground control panel.
DO NOT RAISE MAST OR OPERATE JIB WITH MAST RAISED
WHEN MACHINE IS OUT OF LEVEL.
Overload Light And Alarm
only)
A sensor located on the platform support is actuated
when the maximum rated load is exceeded. In case of
overload, all functions are disabled, the red indicator
on the platform control panel and on the emergency
control panel flash and an acoustic alarm is triggered.
The work platform must be unloaded until the flashing
light and acoustic alarm stop.
Slack Chain Light And Alarm
The slack chain detection system prevents movements
if the platform or the jib come to rest on an obstacle
while lowering the mast or jib.
When a slack chain is detected, the sensor actuates an
acoustic alarm and a red light is lit on the platform
control panel. All functions of the machine, except the
mast and jib raising movements, are disabled.
Procedure to follow in case this feature is activated :
