correct position and torque to 20-25 lb-ft. If unit utilizes O-
ring and jam nut type connectors tighten jam nut to 15-20
lb-ft.
15. Fill the hydraulic oil reservoir until the fluid level
registers full on oil level mark on oil reservoir.
NOTE: Vehicle must be parked on level ground, Plow
must be in the lowered position, and Wings must be
folded rearward ("V") in order to properly check the oil
level. Checking oil level with plow elevated or with wings
straight or folded forward will give wrong reading.
16. Refer to plow operation instructions and operate the
plow to purge all air from the hydraulic system.
17. Replenish the fluid in the reservoir until the fluid level
registers full on oil level mark on oil reservoir.
18. Operate system and check for leaks, repair or tighten
