Procedure for Reel Motor Case Drain Flow Test:
Make sure hydraulic oil is at normal operating tem-
perature by operating the machine for approximately 10
minutes. Make sure the hydraulic tank is full.
9. After achieving 1000 PSI (69 bar), place discon-
nected motor case drain hose into a container gra-
duated in ounces or milliliters (Tool TOR4077: see
SpecialTools)andcollecthydraulic fluidfor15seconds
(Fig. 24).After15 seconds,remove hoseend fromcon-
tainer.

CAUTION
Keep away from reels during test to prevent per-
sonal injury from the rotating reel blades.
8.
Engage reels by positioning the functional control
lever to MOW position. While watching pressure gauge,
slowly close flow control valve on the tester until a pres-
sure of 1000 PSI (69 bar) is obtained.
