When the machine is impossible to drive forward
and in reverse:
ZW310
CAUTION: Before operating the emergency valve
(spool), be sure to apply the parking brake so that the
machine does not start moving.
Should the drive system become inoperable due to trouble
in the electrical circuit such as a broken harness, the travel
system can be resumed by the following procedures.
Procedures
1. Remove inspection cover (1) located at the frame left
side.
2. Remove bolts (3) and lock plate (6) from the side surface
of transmission control valve (2).
3. Press 2nd speed gear stage spool (7) 5 mm and rotate the
spool 90° in either side. (When the spool is pressed, the
machine is set to the drive mode.)
3.1 When traveling forward:
Press forward drive spool (4) 5 mm and rotate the spool
90° in either side in the same way as the 2nd speed gear
stage spool is done.
3.2 When driving in reverse:
Press reverse drive spool (4) 5mm and rotate the spool
90° in either side in the same way as the forward travel
spool is done. (When forward drive spool (4) is further
rotated 90°, the spool returns to the original position
[neutral].)
4. After setting either the forward drive spool or the reverse
travel spool and the 2nd speed gear stage spool in the
drive mode, start the engine.
5. Release the parking brake. As soon as the parking brake
is released, the machine will start moving.
6. After moving the machine, return all spools (4, 5, and 7)
to neutral, secure them in position with lock plate (6) and
bolts (3).
IMPORTANT: Never set both forward and reverse drive
spools (4 and 5) in the drive mode at the
same time. Failure to do so may result in
damage to the clutch.
