1.2. SAFETY AND THE ENVIRONMENT
1.2.1. General safety instructions for maintenance
Excercice extreme caution in all service, maintenance, toubleshooting and repair works. A
faulty device or a device where covers, safety devices or other parts have been removed or
disabled, may function in an unexpected way.
If, during maintenance, it is necessary to disable a safety device, make sure that it is
returned to use and works correctly before using the device.
Beware of sudden and unexpected movements.
Support the platform, boom system, articulated arms and support outriggers in a position in
whichtheloaddoesnotrestonthestructureunderrepairorcauseanyotherdanger(e.g.
transportpositionoruseofsupportingstructures)
While removing hydraulic cylinders, note, that
• they may be oily and slippery
• the cylinders are heavy. Use a suitable crane and lifting accessories for lifting.
Do not let oil spill to the ground
Used oils and oily waste must be properly disposed of. Note the national and local recycling
and waste policies and regulations.
Remember when handling batteries:
Electrolyticliquidishighlycorrosive-Alwayswearprotectiveclothingandeyewear.
Thebatteryemitsanexplosivegaswhilecharging-keepawayfromopename.Explosion
hazard.
Use genuine spare parts. Doing so, you ensure the correct functioning and structural safety
even after major repairs.

DINO XT II
2.1. INSPECTIONS REQUIRED BY AUTHORITIES
Always check the local, state or federal regulations about aerial platform inspections
and inspector qualications from local authorities.
Inspections must be performed in accordance with local, state or federal regulations,
legislation, directives, standards. The manufacturer recommends following inspections, as
required by local authorities in platforms country of origin.
Apre-useinspectionmustbedonebeforetakingtheplatformtouseforthersttimeand
beforerststart-upaftermajorrepairsandalterations.
A thorough inspection and a test loading of the lift must be carried out at least once every
twelve(12)months.
Theplatformshouldundergoamajorinspectionwithinten(10)yearsafterhaving
beenoriginallyputintoservice.Amajorinspectionincludesnon-destructivetestingand
inspectionwhiledis-assembled.
A special inspection should be done if the platform has been exposed to exceptional
circumstances which may have affected the structural integrity of critical components.
The inspections should be carried out on regular basis throughout the service life of the lift.
If the lift is used under extreme conditions, intervals between the inspections shall be
reduced.
Theoveralloperatingconditionoftheliftaswellastheconditionofthesafety-relatedcontrol
devices shall be established in the regular inspections. Particular attention shall be paid to
changes which affect the operational safety.
Duringinspectionsthenoticationsgiveninpreviousinspections,practicalexperience
from use and information on performed repairs should be taken into account and can be
implemented for better safety.
Major and special inspections shall be carried out by a competent person or competent
body, who is familiar with the operation and structure of the lift. The competent person sould
periodically update their knowledge and be able to demonstrate their competency if so
required.
A report should be made of the inspections and the reports should be kept with the unit
stored in the space reserved for it.

3. ROUTINE MAINTENANCE DURING OPERATION
This chapter describes the service and maintenance operations that the operator of the
platform is responsible for.
Othermaintenanceoperationsrequirespecialtraining,toolsandmaterialsorspecic
measurements and adjustment values. They are separately described in maintenance
instructions manual. Please contact your maintenance partner, dealer or manufacturer.
Make sure that all service and maintenance prochedures are performed in time and
according to instructions.
Any faults which may affect the operational safety of the unit must be repaired before the lift
is used for the next time
Keep the lift clean. Clean the lift carefully before any service and maintenance operations or
inspections. Impurities may cause serious problems in for example in the hydraulic system.
Use original spare parts and service kits. See spare part list for detailed information on spare
parts.
The rst service after 20 hours of operation
• changethepressurelterelement
• adjustthebrakesaccordingtotheinstructions(seepoint“Wheelbrakesandbearings”)
• check the wheel bolts for tightness after about 100 km of driving
If the lift is operated under demanding conditions (in exceptionally humid or dusty
environment, corrosive climate, etc.), the intervals between the oil changes and the
other inspections shall be shortened to meet the prevailing conditions in order to
maintain the operational safety and reliability of the lift.
The performance of the periodic servicing and the inspections is absolutely
mandatory, because their negligence may impair the operational safety of the lift.
The guarantee will not remain valid, if the servicing and the periodic inspections are
not performed.

4.1.3. Check the coupling device and overrun
Check the condition of the coupling device and the overrun devise. Check the brakes.
Adjusting the brakes
1. Support the lift by raising its wheels off
the ground.
2. Make sure that the wheels can rotate
freely. The brake rods must be slack
(withthehandbrakereleased).
3. Check the attachment of the brake rods.
4. Turn the adjustment wheel, behind the
hole marked by the arrow, until the wheel
no longer can be turned by hand.
5. Turntheboltcounter-clockwiseuntilthe
wheel can be turned freely.
6. Adjust the braking force with the
nuts, keeping the brake balancer
perpendiculartothetow-bar,sothatboth
wheels will brake.
If you tighten the brake system too
much, the brakes will overheat during
transportation, and the the driving device will
require more force.
We recommend performing a test run after
theadjustmentinordertoensureawless
operationofthebrakesbybraking2-3times.
DANGER
WARNING
CAUTION
