immobilize (Figure 32).

8. Pour hydraulic oil (1.1 liters) to the hydraulic pump
breather plug attachment hole (Figure 30).
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 31).
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.
