2.Remove the breather plug with a 24 mm wrench at the top of the hydraulic hydraulic pump.

3.Remove the hydraulic hose connected to the cylinder on the vibrator side (Figure 30).

4.Set the run lever to reverse.

5.Drain the hydraulic oil from the pump.

6.After the oil is drained, attach the hydraulic hose again to the cylinder on the vibrator side.

7.With the direction control lever at the forward-most position, secure the guard frame with a rope to immobilize (Figure 31).

8.Pour hydraulic oil (550 cc) to the hydraulic pump breather plug attachment hole (Figure 29).

9.Remove the air releasing plug of vibrator cylinder. Oil will then come out from the air releasing plug. After air bubbles stop coming out, reattach the plug. Tighten securely (Figure 30).

10.Release the direction control lever and move the lever forward and reverse several times (until no air bubbles are seen). Keep the lever at the forward position for 10 seconds every time. (Because the check valve is opened at the maximum forward position and air bubble will come out from the oil tank of the hydraulic pump).

11.In case the air bleeding is insufficient, repeat steps 9 and 10.

12.Attach the hydraulic pump breather plug and put on the plug cap. After making sure the hydraulic oil in the pump is at OIL LEVEL, attach the breather plug.

CAUTION

DO NOT exceed OIL LEVEL of hydraulic oil. If the level is higher, oil will burst out from the breather plug.
