Bleeding air from hydraulic tank
After replacing oil and filter element or cleaning strainer, bleed
the air from the circuit.
When changing the oil in the hydraulic tank, or removing the pis-
ton pump, or removing the piping of the piston pump, bleed the
air in the following way after assembling.
After bleeding air from piston pump, bleed air from hydraulic cir-
cuit.
Bleeding air from piston pump
NOTE
If the air is not bleed completely, the piston pump may be dam-
aged, so always carry out the air bleeding operation correctly.
Before bleeding the air from the piston pump, check that the
hydraulic is filled with oil up to the top of the sight gauge. (If the
oil level is low, add oil.) The cap of the hydraulic tank remains
removing, until the air bleeding of the piston pump finishes.
Leave the hydraulic tank cap off until the air is completely bled
from the piston pump.
1. Start the engine.
2. Loosen air bleeders (1), (2), and (3), on the top of the piston
pump.
3. Completely bleed the air until oil overflows from air bleeders
(1), (2), and (3), tighten air bleeders (1), (2), and (3).
4. Check the oil level. If the oil level is low, add oil to the speci-
fied level.
For details, see "Check oil level in hydraulic tank, add oil
(4-53)".
