M0.1 At the end of every working day
- Check that all safety devices are efficient.
- Check the level of the hydraulic oil in the tank.
- Check all the components of the hydraulic circuit for possible leaks.
- Check that the control and the oil diverter levers can easily be positioned;
they must show no signs of forcing.
- Check the condition of shackles, hooks, wire ropes and any other lifting
equipment.
M0.2 After the first 40 hours use
Check the tightening torque of the fixing rods of the
crane (fig. 30).
See table at paragraph M0.4
M0.3 After every working week
Clean the oil filter placed in the oil tank of the crane and
if any, on the pump section and pressure hoses.
NOTE The filters of fibre or paper can not be cleaned,
they must be replaced.
Cleaning of the wire mesh filter on the tank (oil return to
the oil-tank) fig. 31.
- Unscrew the security bolts of the filter cover 1 and
remove it.
- Extract the cartridge, clean by flushing with a non
flammable, non corrosive and non toxic solvent (gas oil
or other). Thoroughly dry the filter inside and out (do not
use compressed air).
- Check if the cartridge has collapsed; if so, replace it!
- Remove the filter body 3 and clean it.
- Re-assemble the filter body and the cartridge: check the
sealing of the ‘O’ ring 4-5-6; in case, replace it!
NOTE
Take care that no contaminated material passes into the tank.
Replacement of the filter on the delivery line (before the distri-
butor) fig. 32.
- When the visual indicator becomes red, replace the cartridge.
- Unscrew with a suitable spanner the filter body (1) from
the head (2).
- Remove the cartridge (3) and replace it!
- Clean inside the holder.
- Re-assemble checking the seal (4) on the filter body.
- Screw the filter body into the head.
Check the oil level in the tank with the crane in the folded
position and with the outriggers (crane and supplemen-
tary) fully re-entered. The oil level must not exceed the
maximum or be lower than the minimum (fig. 33).
Top up using hydraulic oil with the same characteristics as those indicated in the
table at paragraph N0.
