IMPORTANT: Do not start the engine when the
transmission oil level is low. Damage to the
transmission may result. Do not use transmission oils
other than those listed in the "Transmission Oil".
The cap of filler port (1) has the breather function.
Never spray high pressure water to the cap and vicinity
of the cap. Water may enter into the transmission,
damage to the transmission may result.
Before starting the engine, check the transmission oil level
with oil level gauge (2). 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 (1).
When checking oil level before operating the machine,
normally the float in gauge (2) must be higher than the COLD
MIN position. If the float is lower than the COLD MIN 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 (176 °F to 194 °F), the float in the gauge (2)
shall be between the HI and the LO notches at the HOT scale
on the oil level indication 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.
