The safety bar located along the chute extension tray will
stop the chipper when pushed in. The reset button for this
bar sits on top of the chipper chute. When the safety bar
has been activated, a red light will come on signaling that
the operator reset button will need to be pushed before the
feed roller will function. if false trips occur, the reset button
can be held in to override the system. upon start-up, the
safety bar light will be on and will need to be reset before
the feed roller will operate.

extension tray in an upright position. Pushing the safety bar
down will lock the bar. To unlock, lower the extension tray

4.3 HYdraulic Feed mainTenance
noTe: check the reservoir daily for proper fluid level, the
presence of water (noted by a cloudy to milky appearance,
or free water in bottom of reservoir), and rancid fluid odor
(excessive heat).
The hydrostatic pump normally does not require regular
fluid changes. The system filter should be changed at
either 250 hour or annual intervals, whichever comes
first. The fluid and filter should be changed and system
cleaned if the fluid becomes contaminated with foreign
matter (water, dirt, grease, etc.) or if the fluid has been
subjected to temperature levels greater than the maximum
recommended.
There is a greaseable bearing on each side of the main
jack shaft on the main hydraulic feed housing. Grease
periodically.
