WARNING
Reservoir may become very hot. Be careful when placing
hand near reservoir. Reservoir can become hot enough to
cause serious burn.
Step 1. Check for overheated hydraulic oil by carefully placing hand near
hydraulic reservoir.
If reservoir is very hot, set PTO ENGAGE switch to OFF,
shut off engine, let oil cool, then continue operation.
Step 2. Check outside temperature. If temperature is less than 00F
( - 1 7 0C), 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.
