Check Transmission Oil Level

--- every 10 hours (daily)
WARNING: Check the oil level while running the en-
gine with care about the following points.
• Move forward/reverse lever (2) to neutral and turn
parking brake switch (3) ON.
• After leveling the bucket on the ground, move the
pilot control shut-off lever to the LOCK position.
• Set the articulation lock bar.
IMPORTANT: Do not start the engine when the transmis-
sion oil level is low. Damage to the transmis-
sion may result. Do not use transmission oils
other than those listed in the "Brand Names
of Recommended Transmission Oil".
Before starting the engine, check the transmission oil level
with oil level gauge (1). When the oil level is correct, the float
in the oil level gauge shall be in the center with the oil cooled.
Refill the oil as necessary from transmission oil filler port (2).
ZW180, ZW220, ZW250
When checking oil level before operating the machine, nor-
mally the float in gauge (2) must be higher than the COLD
MID position. In case the float is lower than the COLD MID
position, add oil through transmission oil filler port (1).When
the transmission oil temperature is in the normal range of
80°C to 90°C, the float in the gauge (2) shall be between the
HI and the LOW notches at the HOT scale on the oil level in-
dication decal. If the float is outside the appropriate range,
add or drain oil so that the float enters the range between
the HI and LO notches.
ZW310
Check oil level when the oil temperature is low before start-
ing operation. The float in the gauge shall be normally in the
center. If the float is not seen in the gauge and the oil level is
lower than the specified level, add oil until the float is seen
at the gauge center. Take care not to add oil excessively.
