Drain Hydraulic Oil Tank Sump
--- every 250 hours
WARNING: Be sure to work only after oil tem-
perature is low or before operation. Failure to do
so may allow high temperature oil to spray, pos-
sibly causing severe burns.
1. Park the machine on a solid level surface. Position
the machine with the arm cylinder fully retracted and
the bucket cylinder fully extended. Lower the bucket
and blade to the ground. Stop the engine.
2. Leave the machine without operating the machine
until hydraulic oil becomes cool. Then, bleed air
pressure from the hydraulic oil tank.
3. Slowly loosen drain plug (1) on the bottom of the hy-
draulic oil tank to drain water and sediment.
