(18) Hydraulic tank breather (behind cover) (31) Hydraulic tank (33) Filler capHydraulic tank (31) is located on the right side of the front frame. The hydraulic tank is the oil reservoir for the hoist hydraulic system, the braking system, the steering system and the brake cooling system. Oil is placed into the hydraulic tank through filler cap (33). Hydraulic tank breather (18) is mounted to the top of the hydraulic tank.
