3. Lower latch handle (E) (one each side of feeder
house) to hook pivot bar (F). Lift handle to over-
center position to lock. It should take 40 to 50

center. Adjusting the torque of bolts (G) will
vary the handle force required. When handle
force is correct, tighten jam nuts (K).

handle in locked position.
NOTE: If latches do not line up with pivot bar,
adjust adapter side frame panels by loosening
hardware at (L) (four bolts per side) and sliding
panels to suit.

CAUTION: Pump may be hot. Wear
gloves when handling pump.
