15. Oil Filling & Bleeding: Use Dexron III ATF, or
Hydraulic Fluid that meets ISO 32 specifications. Remove
fill-breather cap, Fig. 8a. Pour in (8) quarts of fluid.
Start unit, raise lift about 2 ft. Open cylinder bleeders
approximately 2 turns, Fig. 9a.
Close bleeders when fluid streams. Torque values for the
bleeders are 15 ft. lb. minimum and 20 ft lb. maximum.Fully
lower lift. Add more fluid until it reaches the
MIN_____ mark on the tank. Replace fill-breather cap.
CAUTION
If fill-breather cap is lost or broken, order
replacement. Reservoir must be vented.

After installing arms and pins, install arm Restraint Gears
as follows: Install Restraint Gear onto arm clevis, as
shown, Fig. 17b. Ensure side of gear marked TOP is facing
upward, Fig. 17b.
NOTE: TOP is stamped on top side of gear. You may
need to pull up on the pin-ring to allow enough room to
install Restraint Gear.
Then, install the (2) 3/8"-16NC x 1-1/2" HHCS (8 total for
all 4 arms) and 3/8" Spring Lockwashers into the gear and
arm, but do not tighten. Reference Fig. 17c, Fig. 18, and Fig.
19.
Torque the Restraint Gear bolts to 30-34 ft.-lbs.
