LED MAINTENANCE
When the maintenance LED is on, the following actions should be performed:
CLEANING
Keeping the equipment cleaned is essential to ensure a good use and durability of the set. It is necessary
to make a periodical thorough cleaning, especially in areas exposed to dirt that could suer damages, such
as gears, connectors, switches, etc. Do not use high-pressure cleaning, they can damage the electrical ele-
ments.
The equipment has a timer with memory of the time that the device is on and activates the
maintenance LED when it exceeds 3000 hours in operation.
If 4000 hours of operation are exceeded, the ERROR LED will light.
To reset the timer and maintenance LED, set the following key combination in less than 5 seconds:
- Press while holding down the Up and Down keys during the sequence.
- Press the Lights On / O key twice
- Press the Buzz On / O key twice

WEAR AREAS
Regularly examining the system’s components to check if they are wearing out is a preventive measure that
can reduce breakdowns. Verify possible lubricate leaks, grooves or bearings in poor condition.
ELEMENTOS DE FIJACIÓN MECÁNICA
Generally we call mechanical xing to the components that are used to attach joint products, mainly screws
and derivatives.
Verify that there are no loose, worn, or missing parts. Examine periodically every moving element to ensure
that they are all tighten.
In some conditions of use, due to vibrations or impacts, many elements could lose their tightening torque
or hold properties.
Periodically examine that no elements are unleashed, especially in the moving parts of the set. Take into
account and always respect the recommended tightening torques.
GREASE
Generally, every moving part should be greased. Our products leave the factory completely greased and
lubricated, however, it is possible that with the time and usage of the product the elements degrease, either
by loss of lubrication or by dirt. Clean and grease periodically the aected zones according to the manufac-
turer’s specications.
REPLACEMENT OF COMPONENTS
This instruction manual does not include procedures for every part. The service sta typically substitutes
cables, switches and certain mechanical parts without any step by procedure.
The qualied service personnel must contact our sales department for information about ordering pieces
and its installation.
IMPORTANT: Do not grea-
se the platform guide
WARNING: Do not lubrica-
te the platform, neither the
stretcher, once connected
to the electricity network.
