MAINTENANCE PROCEDURES
7.
Loosen the screws (1), remove the plate (2) and slowly loos-
en the filler cap (F) to release the residual pressure from the
tank.
8.
Remove the drain plug (P) and let the oil flow out, gathering it
into a container with suitable capacity.
9.
Loosen the clamps (3), remove the suction pipe (4) and let
the oil that is still in the tank flow out.
10. Remove the screws (5), remove the flange (6) and clean the
air intake filter (7).
IMPORTANT
Carefully check the filtering element grid and if it is not in
q
perfect conditions, change it.
11. Put back the drain plug (P), the lower flange (6) with the filter
(7), checking the soundness of the gasket, and the suction
pipe (4) with the clamps (3).
12. Fill with prescribed oil until reaching the level (G).
Use only oil of the prescribed type (see «4.4 FUEL, COOL-
ANT AND LUBRICANTS »).
13. Close the cab floor.
14. Extend the boom, arm and bucket cylinders completely, as
shown in the figure, and remove the filler cap (F).
Put back the cap and pressurize the tank by lowering the
equipment to the ground.
15. Make sure that all the control levers are in neutral position
and let the engine idle for at least 2–3 minutes before operat-
ing the work equipment.
Move each piston more than once to deaerate the system;
check and top up if necessary.
Do not start the engine with empty tank, since this would
q
certainly damage the pump.
