Inspecting The Hydraulic Oil Tank Level And Refilling - Takeuchi TB 250 Workshop Manual

Inspecting the hydraulic oil tank level and
refilling
WARNING
Oil may spurt out if caps or filters are removed or pipes
are disconnected before releasing the pressure in the
hydraulic system.
• Slowly loosen the air-bleeding plug to relieve the in-
ternal pressure of the hydraulic oil tank.
• Press the air breather button to relieve the tank pres-
sure (models with air breather).
Machine setup for inspecting the hydraulic oil level
1. Start the engine and run it at low speed.
2. Fully retract the arm cylinder and bucket cylinder and
lower the bucket to the ground.
3. Stop the engine.
4. Inspect the oil level using the sight gauge (1).
At an oil temperature of about 20°C, the level in the
tank should be halfway between the upper limit (H) and
the lower limit (L). If it is below the lower limit (L), refill.
At an oil temperature of about 50 to 80°C, the level
should be near the upper limit (H).
