Oil Replacement (Hydraulic Oil Tank)

Every 2,000 Hours orEvery 2 Years

Every 4,000 Hours orEvery 4 Years

[NOTICE]

◆ After the hydraulic oil has been replaced, the hydraulic pump must be bled since air may be present in the suction side of the pump. The hydraulic pump could experience failure if it is operated without first bleeding it. The hydraulic pump must not be operated after replacing the hydraulic oil unless it has been properly bled. For instructions on how to bleed the hydraulic pump, contact the nearest TADANO distributor or dealer.

Checking Oil Level

1. Stow the crane in the traveling configuration on level ground.

2. Check the oil level with the oil level gauge. The oil level gauge is marked taking into account the effect of oil temperature. Check whether the oil level is between the "0°C" mark and the mark corresponding to the current oil temperature.

If the oil is low, remove the cap on the hydraulic oil tank and add oil through the filler port.

- Example -

When the current oil temperature is 68°F (20°C), there is sufficient oil in the tank if the oil level is between the 0°C and 20°C marks.

◆ When the oil temperature is 32°F (0°C) or lower, regard the "0°C" mark as the proper level.

Replacing Oil

◆ Replace the oil within 250 hours or 3 months after the machine has been delivered (whichever comes earlier):

• Replace it every 4,000 hours or 4 years after that.

(Applicable to TADANO hydraulic oil LL.)

• Replace it every 2,000 hours or 2 years after that.

(Applicable to other than TADANO hydraulic oil LL.)

◆ When replacing the hydraulic oil, also replace the return filter.

1. Stow the crane in the traveling configuration on level ground.

2. Remove the cover from the filler port and use an oil pump to pump the hydraulic oil from the tank into an oil drum or other suitable container.

3. Remove the drain plugs at the bottom of the tank to release any remaining hydraulic oil.

4. Check the inside of the tank and clean if any dust or foreign matter is found.

5. Clean the drain plug and wrap sealing tape around it, then reinsert and tighten.

6. While watching the oil level on the level gauge, add new hydraulic oil into the tank.

7. Remount the cover on the hydraulic oil tank.

8. Bleed the hydraulic pum.

9. Check the oil level again. If low, add more hydraulic oil.

Return Filter (Hydraulic Oil Tank) Every 500 Hours or Every 6 Months

1. Remove the top cover on the hydraulic oil tank and take out the return filter.

2. Remove the snap pin and then the nut from the return filter.

3. Replace the filter element with a new one and reassemble the return filter.

Air Breather (Hydraulic Oil Tank) Every 500 Hours or Every 6 Months

Unlock the air brether cap to remove it. Remove the two bolts, then use a wrench (spanner) as shown in the figure to remove the element holder. Replace the element with a new one.

◆ The air brether cap lock is provided on the machine with and after S / No.540245.

4. Install the return filter in the tank and remount the cover.
