INTRODUCTION
In this chapter you will find all the ordinary maintenance operations to be executed both during the running in period and
periodically. Moreover, you can find all information concerning type of fuel, greases and oils to be used on your machine in
order to assure the highest reliability, efficiency and lifetime.
SAFETY INFORMATION AND GENERAL RULES
To be sure the machine is used in maximum safety, reliability and efficiency conditions, it is fundamental to regularly carry out
the ordinary maintenance interventions and to closely follow the instructions provided in this Operator Manual.
Do not use the machine until all needed maintenance operations and repairs have been carried out.
If the operator detects that the machine operation is not optimal and does not meet safety requirements, the fault shall be
immediately notified to the responsible person.
Before carrying out any intervention on the machine, it is necessary to stop the engine, position the driving direction selector in
central position and the gear selector in neutral position.
It is strictly forbidden and highly dangerous to change any machine component by modifying its original structure. It is also
forbidden to change the hydraulic and electric settings or to alter the safety systems. Otherwise, Merlo S.p.a shall be waived of
any liability and guarantee claim.
WARNING! Maintenance operations shall be executed by skilled and competent personnel. For interventions
on components which are excluded from the ordinary maintenance described in this Manual, contact Merlo Technical
Support Service.
ENVIRONMENTAL INFORMATION
WARNING! Always comply with the environmental laws of the country where the machine is used.
It is strictly forbidden to unload or discharge oils, filters or any other source of environmental pollution. Pay particular
attention to safe waste disposal of such materials which are dangerous for people and the environment – in such
cases, contact the responsible organisations.
When handling lubricants, wear all appropriate personal protection devices (gloves, masks, overalls, etc.).
In order to avoid any personal burns or fires, do not work on heated fluids or components.
INFORMATION ON ORIGINAL MERLO SPARES
WARNING! Maintenance operations on Merlo machines must be carried out using only original and approved
spares. If non original spares are used, Merlo shall be waived of any liability and all machine guarantee terms shall be
voided.
MAINTENANCE INFORMATION
In case of machine failure, the operator shall switch off the diesel engine as soon as possible, take out the engine start key, get
off the machine and check the extent of the problem. Please note that maintenance operations shall be carried out by skilled,
trained personnel when the machine is standing still.
All maintenance operations shall be carried out indoor, in a properly equipped workshop. Before starting any maintenance
operation, please male sure that the following conditions are met:
-
never carry out maintenance operations you are not familiar with. Always follow the instructions provided in the Operator's
Manual and, if necessary, contact the Merlo Technical Support Service.
- place the machine on a flat, compact ground, having a maximum slope of 3%.
- retract and lower the telescopic boom of the machine completely.
- remove any loads or attachments fitted on the machine and place them on the ground.
- shift both the gearbox selector and the operating mode selector to the neutral position.
- switch off the diesel engine and take the engine start key out of the dashboard.
- with the engine off, operate the control levers to relieve any residual pressure from the oil circuit.
- place wheel chocks under both front and rear wheels of the machine to prevent accidental movements.
- always use personal protection devices (accident prevention shoes, gloves, dust mask, etc.).
- take all the necessary accident prevention measures for the kind of operation to be carried out.
- only replace lubricating oil when its temperature drops below 60°C (140 °F)
- carry out all maintenance operations at least 4 hours after switching off the engine, so that any contact with hot machine
parts can be avoided.
- when using compressed air for cleaning and blowing operations, make sure that the maximum pressure is 2 bar (29 psi).
Always wear protection goggles when using compressed air.
- use either a ladder or an access platform - compliant with the law as it stands - if you need to carry out maintenance
operations on the machine at a height exceeding 1.50 m (5 ft) from the ground.
