Draining The Hydraulic Oil Tank (Only For Machines In Which Synthetic Biodegradable Oil Type Hees Is Used) - Komatsu PC14R-3 Operation & Maintence Manual

4.9.5.g DRAINING THE HYDRAULIC OIL TANK
(Only for machines in which synthetic biodegradable oil type HEES is used)
To carry out this maintenance operation it is necessary to tilt the cab floor. Carefully follow the instruc-
q
tions given in paragraph "3.2.9 TILTING THE CAB FLOOR (machines with canopy)" or have this opera-
tion carried out by your Komatsu Dealer.
Retract the arm and bucket cylinders completely, rest the bucket teeth on the ground and, after stopping
q
the engine, eliminate the residual pressures from the equipment (by shifting the controls more than
once) and from the tank (by slowly loosening the filler cap).
Let the oil cool down until it reaches 40÷45°C before carrying out this maintenance operation.
q
Immediately clean any area dirty with oil.
q
Oils, filters, the coolant and the battery are considered special waste and must be collected and dis-
q
posed of according to the regulations in force.
1. Turn the turret so that the lower part of the hydraulic oil tank
is not covered by the tracks.
2. Retract the arm and bucket cylinders completely and lower
the boom until the bucket teeth rest on the ground.
3. Lower the blade to the ground.
4. Stop the engine and eliminate the residual pressure from the
work equipment (by shifting the controls more than once).
5. Tilt the cab floor (see "3.2.9 TILTING THE CAB FLOOR (ma-
chines with canopy)").
6. Loosen the screws (1), remove the plate (2) and slowly loos-
en the filler cap (F) to release the residual pressure from the
tank.
7. Remove the drain plug (P) and let all the condensate flow out
of the tank. Collect the condensate in a container with suita-
ble capacity.
8. Put back the filler cap (F).
9. Close the cab floor.
IMPORTANT
The tank must be drained before starting the engine, with
q
temperatures exceeding 0°C; when the temperature is be-
low 0°C, the tank must be drained at the end of work or in
any case with the machine at operating temperature, to
prevent the condensate from freezing.
