Swing Bearing Mounting Bolt Check

Every 500 Hours or Every 6 Months

WARNING

If the mounting bolts come loose and/or break, the crane's upper and lower structures will be separated, resulting in a serious accident. Check the bolts at regular intervals. If they are loose, have the nearest TADANO distributor or dealer retighten them. The bolts should be checked at least once a year by a TADANO distributor or dealer.

Accelerator Circuit Bleeding

Whenever Necessary

◆ When air is being bled, the level of oil in the oil reservoir will drop as the oil is discharged from the circuit. Bleed the air, while at the same time supplying the reservoir with new hydraulic oil in order to prevent air from entering the circuit.

1. Bleed the accelerator circuit, using the bleeder screws (2 points) on the inside of the swing table, as follows:

(1)Connect one end of a vinyl hose to the bleeder screw and place the other end in an oil pan.

2. After bleeding the circuit, repeat the above steps to bleed the accelerator cylinder, using the bleeder screw located at the rear of the hydraulic oil tank.

(2)Pump the accelerator pedal twice or three times, then keep it depressed. Loosen the bleeder screw and release the air from the circuit.

(3)When the flow of oil weakens, tighten the bleeder screw and release the accelerator pedal.

(4)Repeat steps (2) and (3) until oil flows out free of air from the bleeder screw.

3. Check the oil level in the reservoir. Add if low.
