· When the oil temperature is about 20°C
(68°F):
The level should be between the upper
limit (H) and the lower limit (L).
If it is below the lower limit (L), replenish.
· When the oil temperature is about 50 to
80°C (122 to 176°F):
The level should be slightly below the
upper limit (H).
Replenishing
