When carrying out final adjustments in the levelling
of the chassis it is important that the last operation
on each Outrigger be an extension. This is to avoid
creating a reduced hydraulic pressure within the
Outriggers and hence negate the possibility of
minor settling.
ELEVATING & LOWERING THE TL33
WORK PLATFORM
When the TL49 has been thoroughly inspected, and has
been set up in accordance with the correct Outrigger
Deployment procedures, the Elevating Assembly can then
be used.
LOOK up and around for obstructions before
performing the lift function.
ENSURE that the Elevating Assembly is clear of
the Chassis before engaging the Slew operation.
DO NOT overload the platform
DO NOT operate within 10 feet (3 metres) of any
electrical power cables. THIS WORK
PLATFORM IS NOT INSULATED.
Cordon off the area within the platform’s working
area to keep passers-by clear of the booms.
NOTE: Chassis controls are for service use only.
1.
Enter the Platform through the entrance provided
and ensure that the Drop Bar is in position. Where
applicable lock the Entry Step in the raised position.
2.
Before using the machine all local Safety
Regulations involving helmets and restraining
devices should be observed. Safety harness
lanyards, not exceeding 1 m in length, should be
attached to the anchor points on the Platform floor.
3.
Ensure the ‘ON/OFF/OVERRIDE’ switch on
the Upper Control Box switch is turned to the
ON
, the Keyswitch on the Outrigger Control Box is
turned to
CHASSIS
position and all Emergency
Stop Buttons are
OFF
(twisted clockwise).
4.
Check the green “System OK” L.E.D. is
WARNING
DANGER
illuminated. If not, and/or an audible alarm sounds,
check that the Outriggers are correctly deployed and
that the machine is level. The boom functions, nor
the slew function will operate if this is not correct.
5.
Select “Boom 1” on the Function Selector Switch.
Check for overhead obstructions and when satisfied
squeeze the red Interlock control on the Joystick.
Slowly move the Joystick forward to elevate
Boom 1. The further the joystick is moved, the
faster the boom will move. Pressure must be applied
to the Interlock at all times while operation is
required.
6.
Select “Boom 2”, “Telescope” or “Rotate” as
required using the ‘Function Selector Switch’ and
operate as described above. For boom one or two
functions the controls will be forward for UP and
backward for DOWN. For telescope retract the
Controller Joystick should be moved forward and for
rotate Telescope extend move the Controller
Joystick backward. To rotate (Slew) RIGHT the
Controller Joystick should be moved forward and to
rotate (Slew) LEFT move the Controller Joystick
backward.
7.
Before lowering, check beneath the Platform floor
for obstructions. Operate as described above,
moving the Joystick to lower the Booms.
LEVELLING
NOTE:
The Cage Levelling function will only work when the
Boom Rest Limit Switch has been activated i.e. when
the Booms are stowed.
The platform can be levelled from the Upper controls using
the levelling switch (See Figure 1). To activate this switch
the ‘ON/OFF/OVERRIDE’ switch, also located on the
Upper Control Box, must be held to the
OVERRIDE
position.
This switch is for fine adjustment of the slave levelling
cylinder. Care should be taken when performing this
operation. The switch should be operated cautiously to
level the cage
slowly.
Activate the switch in a careful,
controlled manner.
EMERGENCY SITUATIONS &
EMERGENCY OVERRIDE
In any emergency situation, the first action to be taken
should be to hit the red “Emergency Stop” button. This will
give instant cutout of all functions. It will then be required
to twist the button clockwise to release before the machine
can be operated again.
