Test the Emergency Stop
DINGLI requires that this procedure be
performed every 250 hours or quarterly,
whichever comes first.
A properly functioning Emergency Stop is
essential for safe machine operation. An
improperly operating red Emergency Stop
button will fail to shut off power and stop all
machine functions, resulting in a hazardous
situation.
As a safety feature, selecting and operating
the ground controls will override the platform
controls, except the platform red Emergency
Stop button.
1 Turn the key switch to ground control and
pull out the red Emergency Stop button to
the on position at both the ground and
platform controls.
2 Push in the red Emergency Stop button at
the ground controls to the off position.
⊙ Result: No machine functions should
operate.
3 Turn the key switch to platform control and
pull out the red Emergency Stop button to
the on position at both the ground and
platform controls.
4 Push down the red Emergency Stop button
at the platform controls to the off position.
⊙ Result: No machine functions should
operate.
Note: The red Emergency Stop button at the
ground controls will stop all machine operation,
even if the key switch is switched to platform
control.
B-5
Lubricate the Lifting Chains
Lubricated chains are essential to good
machine performance and safe operation.
Extremely dirty conditions may require that the
chains be cleaned and lubricated more often.
The direct result of wearing the transmission
chain is to stretch the total length of the chain.
Measure the stretching rate of the used
transmission chain by eye every three months.
The mast connected to the elongated chain
would be lower in position so that the top of
each mast is obviously uneven in ‘stored’
position. It may lead to damage on guide roller
if the problem is serious.
Every link of the transmission
chain is associated with three links of the
masts.
1 Lower the platform to the stowed position.
2 Measure the maximum height of the
machine.
⊙ Result: The machine should be no lower
than specification.
¤ Result: The machine should be lower than
specification.
The following sketch shows the connection of
the masts and the transmission chain.
