MERLO PERIODIC MAINTENANCE PROGRAMME
This paragraph gives the periodic maintenance schedule that must be carried out on the machine, scrupulously respecting the
established intervals. In the event of use in particularly harsh conditions, maintenance must be carried out at shorter intervals
The machine maintenance schedule is based on:
- working time bands (every 10 hours, 50 hours, 500 hours, 1000 hours, 1500 hours)
- working periods (daily, weekly, every 6 months, every 12 months, every 18 months)
The time bands and periodic intervals are combined as follows:
1) EVERY 10 HOURS OR DAILY
2) EVERY 50 HOURS OR WEEKLY
3) EVERY 500 HOURS OR 6 MONTHS
4) EVERY 1000 HOURS OR 12 MONTHS
5) EVERY 1500 HOURS OR 18 MONTHS
The operator must perform routine machine maintenance considering which of the 2 situations (hourly or periodic) occurs first.
All the maintenance operations must be performed cyclically. At each maintenance interval, perform also the operations
described in the previous intervals: for example every 1000 hours perform also the maintenance contemplated at 500, 50 and
10 hours. The 5 scheduled maintenance intervals, summed up in the following table, will then be analysed individually in the
subsequent paragraphs.
CAUTION!
• Maintenance of your machine must be performed by qualified and competent personnel.
• To perform maintenance operations correctly, position the machine on a flat, solid surface.
• Before performing maintenance make sure that the diesel engine is turned off and that the battery cut-off switch (if
present) is in OFF position
• To know which oils and greases to use for machine maintenance, refer to the paragraph "FUELS AND LUBRICANTS"
in this chapter and to the OILS TABLE in the chapter "CONTROL STICKERS - LEAFLETS IN CAB". The grease nipples
not mentioned in the maintenance table are to be greased periodically every 1000 HOURS or 12 MONTHS depending
on the actual conditions of use of the machine.
• Always use original spare parts approved by Merlo S.p.a.
• To know the times and the maintenance jobs to be done on the diesel engine, always refer to the engine manual
supplied with the machine.
• It is advisable to make a note of the date when maintenance is carried out so as to perform the operations regularly.
