When approaching the end of a log, it may be necessary
to manually override the automatic feed sensor. Be sure
to pay attention to the engine speed and feeding of
the material.
STeP 1. iniTiaTing Program moDe
Hold down the “S” button while turning the engine key
to the “on” position until “l” starts to flash on the lCD
(Figure 3.8).
STeP 2. enTer loW (l = loW) rPm
The low setting is the RPM speed where the feed roller
stops. The “up” arrow increases the RPM setting, while
the “down” arrow decreases the RPM setting. Setting the
speed lower causes the engine to lug down more before
the feed roller stops.
Hold the appropriate (either up or down) arrow until 1.
the desired RPM speed is displayed (Recommended
1375 rpm).
Push the “S” button once with the desired RPM setting

save.
STeP 5. enTer reTurn
(reT = reTurn) rPm
The return setting is the RPM speed where the feed roller
restarts. The feed roller should restart before the rotor
reaches “normal” RPM to maximize chipper efficiency.
Setting the speed higher allows the engine to recover more
before the feed roller restarts.
Hold the appropriate (either up or down) arrow until 1.
the desired RPM speed is displayed (Recommended
1400 rpm).
STeP 6. enTer number of PoleS
(iPu=number of PoleS)
The number of poles is used to indicate the number of
speed pickup devices.
Hold the appropriate (either up or down) arrow until 1.
