TL33 Work Platform 3-7
ELEVATING PLATFORM
LOOK up and around for obstructions before
performing the lift function.
DO NOT overload the platform
DO NOT operate within 8 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
boom.
1. Ensure key switch is turned to "Cage" position
and both emergency stop buttons are released
(out).
2. Enter cage through gate and ensure drop bar is in
position.
3. Wear safety helmets/harnesses in accordance
with local requirements. Safety harness
lanyards, not exceeding 1m in length, should be
attached to anchor points in cage floor.
4. Check green "System OK" L.E.D. is illuminated. If not,
and/or audible alarm sounds, check that outriggers are
correctly deployed. Booms will not operate unless this
is done.
5. Select "Boom 1" on function selector switch.
6. Check for overhead obstructions.
7. Squeeze "deadman" control on Joystick and slowly
move Joystick forward to elevate boom. The further
the joystick is moved, the faster the boom will move.
Pressure must applied to the "deadman" at all times
operation is required.
8. Select "Boom 2" or "Rotate" as required and operate as
described above . Note: Move joystick forward to
rotate left , back to rotate right.
9. Before lowering, check under cage floor for
obstructions, operate as described above, moving
joystick back to perform 'lower' function.
10. In an emergency, hit the red "Emergency Stop"
button for instant cut-out of all functions. Twist button
clockwise to release before operating machine again.
11. If the Audible warning alarm sounds, control functions
will cease to operate. This will be due to a loss of
pressure on one or more of the outriggers. Do not
attempt to elevate the booms with the alarm sounding,
unless this action is required to move the boom away
from an obstruction. In this event, movement should
be kept to a minimum.
Turn the cage "on/off" switch to the 'emergency'
position, and hold it in this position while using the
boom controls as normal to descend immediately to
ground level. Do not rotate until close to the ground.
After leaving the cage, check all outriggers and adjust
to ensure each is correctly deployed. Note that during
emergency operation, controls will operate only at a
fixed, slow speed.
When operating this function, extreme care must be
taken to ensure person carrying out the task does
not become trapped by the structure
EMERGENCY LOWERING
1. Should the machine become inoperable when elevated
ask a person on the ground to lower the platform using
the emergency lowering valves.
2. These are red knobs (twist or push type )mounted at
the base of the hydraulic lift cylinders (See Figure 3-4).
Operate the lower boom first by turning slightly in an
pushed) - ensure rate of descent is kept slow and under
control.
Descent can be halted at any time by turning the red
knob clockwise until the valve is closed.
3. Repeat the operation if necessary for the upper boom
when cylinder is in reach of the ground.
4. Tighten valves clockwise before using the machine
again.
