REMOVE PLUG
AND INSTALL
PRESSURE GAUGE
If feed wheels start to run slow when
engine RPM is high, check hydraulic
pressure.
Remove the plug in the top right rear
corner of the hydraulic block, hole
marked “G”, and install a pressure
gauge.
Test the hydraulic pressure. With the
engine at idle and with the cutter disk
disengaged, run a log between the feed
wheels and butt it against the cutter disk.
Turn Auto-Feed off to operate feed
wheels with engine at idle, see Machine
Controls section. Check the pressure
reading.
The overall hydraulic pressure setting is
2500 PSI, preset at the factory, and
should remain set at that pressure.
