INTRODUCTION AND WARRANTY CONDITIONS
1.1 Introduction
LEGUAN LIFTS wants to thank you for purchasing this Leguan access platform. It is the result of Leguan’s long
experience in design and manufacturing of access equipment.
We ask you that you read and understand the contexts of this manual completely before operating the access
platform. This will improve your operating and maintenance efficiency, help avoid breakdowns, damage and
extend the life of your machine.
1.2 Display of safety instructions
Safety sign, signal word
Meaning
Identifies a dangerous situation that will result in
death or serious injuries if not avoided.
Identifies a dangerous situation that may result in
death or serious injuries if not avoided.
Identifies a dangerous situation that will result in
moderate or minor injuries if not avoided.
Damage to equipment: the product or the
environment risks damage.
Pay special attention to these symbols. They indicate important safety factors that require special attention.
Every operator must read and understand this manual before starting operation, and the instructions in this
manual must be followed. If you are lending the access platform out to somebody, make sure that they
familiarize themselves with and understands these instructions. If there is anything unclear with the operation,
please contact your Leguan dealer.
If spare parts are needed, use only original LEGUAN parts. They will provide your machine with the maximum
life expectancy and ensure optimum safety.
It is not possible to give explicit operating instructions to all operating conditions of the machine. Therefore,
the manufacturer is not responsible for any damage caused by eventual faults in this Operators Manual.
The manufacturer does not accept any responsibility for consequential losses resulting from the use of this
self-propelled access platform.
The lifespan of the track system of an access platform on rubber tracks is heavily dependent on the working
environment and work methods. If the access platform is being used on terrain with stones or gravel, on
demolition sites with concrete, or in an environment with scrap metal, the lifespan of the track system may be
significantly reduced. Therefore, damage to the tracks, track rollers or crawler track chassis, caused by
operation in such environments, is not covered by warranty.
The machine operator can influence the service life of the tracks by complying with instructions for their use
and maintenance.

1.3 Warranty conditions
This product is warranted for a period of twenty-four (24) months without hour limit. In the event a fault
occurs which is attributable to manufacturing or assembly defect, contact the dealer without delay.

ends. Warranty repair that has been started will be completed regardless of the ending date of warranty
period.
A condition for the warranty is that both the buyer and the seller have accepted the delivery. If the buyer is
not present when the delivery takes place and doesn’t make a complaint within 14 days of delivery of this
access platform, it is considered that the sale is closed and the warranty period has started.
Warranty is limited to the repair of a faulty access platform without cost at an authorized Leguan service
workshop. The warranty period for parts that are changed in connection with the repair will end when the
warranty period for the access platform ends. Parts that have been changed in the warranty repair will remain
Leguan Lifts’ property without compensation.

-Wrong or negligent use of this product, or mischief.
-Acts of vandalism.
-Any repairs or modifications to the product, performed without the prior authorization of the
manufacturer.
-Not following service and maintenance instructions.
-Machine breakdowns due to causes other than a manufacturing error.
-Adjustments, repair and the replacement of parts due to normal wear and tear, negligent use or non-
compliance with the instructions for use.
-Exceptional strain placed on the access platform, sudden and unforeseeable events, natural disasters.
-External, mechanical or chemical causes (damage to the paintwork, such as scratches and abrasions
caused by flying stones, pollution and environmental impurities, strong detergents, or by lifting
operations or lifting equipment).
-Any patterns or uneven patches on the paintwork.
-if the warranty claim is not submitted within reasonable time of the buyer observing the flaw or when
the flaw should have been noticed. Notification must always be submitted within two (2) weeks of the
buyer noticing the defect. - under all circumstances, the buyer must act so that his action does not
make the defect(s) worse.
-The manufacturer does not accept any responsibility for consequential losses resulting from the use of
