Note: A minimum of 7 gal - 8 gal (26.5 L - 30.3 L) of
hydraulic oil is needed to fi ll the empty reservoir tank to
the correct amount. The maximum volume capacity of the
hydraulic reservoir tank is 9.9 gal (37.5 L). Do not fi ll to this
maximum capacity!
6. Visually see if the hydraulic oil level is at or above the
sight gauge. Confi rm the hydraulic oil level is within the
high and low markers on the dip stick. Add or remove
hydraulic fl uid as needed. (Reference approximate fi ll
line)
