5.5. QUARTERLY CHECK
The quarterly check must be done when the machine is clean and has to be registered.
The operator is recommended to wear gloves, glasses, proper clothes and to have his
hair protected.
Pay attention when using compressed air or water under high pressure and check no
other people are in that area; it is better that only one person make the ordinary check.
If the work has not been completed, leave a sign on the machine in order not to allow
its usage.
When opening the hoods from the engine, the batteries and the hydraulic main circuit,
be aware of this:
 The batteries are not covered and so it is recommended not to allow fl ames or
fi res near them. It is also recommended to wear glasses
 The temperature in some parts may overcome the ordinary level, so it is
recommended not to touch any part without gloves
It is recommended to execute these operations:
 Check the inspection register to verify the completeness of the previous
maintenance operations
 Check all the safety devices electrically and mechanically like showed in the
paragraph 5.13
 Daily and weekly execute all the maintenance operations.
 Grease the telescopic extensions of the arms using a brush
 Lubricate chain for the boom extension with a brush and check it (see paragraph
5.12)
 Check the state of the oil in the tank: it must be coloured in light yellow; it must not
present foam or look milky because of the presence of water
 Verify the absence of oil leaks or damage to fl exible pipes in the articulations of the
arms or inside the frame (lift the machine on the stabilizers and look beneath the
chassis)
 Check the oil levels and the amount of hours the thermal engine has been running;
therefore execute all the maintenance operations or the needed replacements.
Clean the edge of the caps in order not to let powder in
 Check the level of the electrolyte in the batteries
 Inspect the arms next to the pivots or the sliding pads, in order to verify the absence
of damages in the joins, maybe caused by crashes or by unusual vibrations
 Put the tracks under tension using the greasing pump (see previous chapter)
 Using a dynamometrical wrench, check the bolts of the slewing (see the following
table)
