2. WINCH CABLE WILL NOT REEL OUT OR IN OR OPERATES
SLOWLY IN REMOTE CONTROL.
Step 1. Set H.D. WINCH CONTROL switch to MANUAL.
Operate winch OUT and IN from manual control station.
If cable will reel OUT and IN, notify organizational
maintenance.
Step 2. Check outside temperature. If temperature is less than 0oF
(-17 oC), hydraulic oil may not flow easily.
Operate engine for 20 minutes with PTO ENGAGE switch
set to ON to bring oil to operating temperature.
If oil is still not warmed, with crane in stowed position,
push MAST control lever down. Hold MAST control down
for approximately 30 seconds, then return to neutral
position. Repeat procedure several times until oil is
warmed.
If problem remains, notify organizational maintenance.
