MAINTENANCE PROCEDURE
199
3 - Once the oil has been drained, disconnect the suction
pipe (3) and remove the flange (4) after removing the
screws (5). Use a 17 mm hexagon spanner.
4 - Clean the filtering element (6).
5 - Put back the flange (4), the filter (6), the gasket (7) and
the lower plug (2).
6 - Fill the tank with the prescribed oil until reaching the level
(8). Use only the prescribed type of oil (see "4.3 FUEL,
COOLANT AND LUBRICANTS").
7 - Raise the cab (see "3.5.3.1 RAISING THE CAB") sure
that the oil in the hydraulic pump reaches the maximum
level. To do this, remove the upper plug (9 and make sure
that the hole is completely filled with oil. Use a 1/2” square
section spanner.
8 - If the oil does not reach the maximum level, top up with
the prescribed oil (see "4.3 FUEL, COOLANT AND LU-
BRICANTS").
9 - After the check, lower the cab, screw the filling cap (1),
close the rear panel and the engine hood and deaerate
the system.
10 - Make sure that all the control levers are in neutral position
and let the engine idle for 2-3 minutes before operating
the work equipment.
Move each piston more than once to deaerate the sy-
stem; check again and top up if necessary.
CAUTION
q
Never start the engine with empty tank, since this would
certainly damage the pump.

tions carried out by your Komatsu Dealer.
