reseTTing dailY Hour meTer (oPTional)
The feed sensor is equipped with an hour meter to track
hour usage. The hours will continue to accumulate until
reset by the operator.
To reset the hour meter:
Stop the engine and make sure the chipper blades and 1.
all moving parts are completely stopped.
Turn key switch to "ON" to energize the feed sensor.
2.
Push the "S" button until Day flashes on the LCD 3.
display.
Depress the "S" button for five seconds and release.
4.
Push and hold down the "S" button for an additional 13 5.
seconds until daily hours are reset to zero.
Some models may have the optional Lofa hydraulic feed
sensor installed. To reset the Lofa program, refer to the
instructions below.
The following settings are recommended:
loW = 1400 RPM
normal = 1675 RPM
HigH = 0
reTurn = 1425 RPM
Poles = 1
sTeP 1. iniTiaTe Program mode
hold down the "S" button while turning the engine key to
the "on" position until "L" starts to flash on the LCD.
sTeP 2. enTer loW rPm (l=loW)
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.
1. hold the appropriate (either up or down) arrow until
1400 RPM is displayed.
2. Push the "S" button once to save.
noTe: do not choose a setting equal to or below zero.
sTeP 3. enTer normal rPm (n=normal)
The normal setting is the RPM at which the chipper rotor
usually turns.
1. hold the appropriate (either up or down) arrow until
1675 RPM is displayed.
2. Push the "S" button once to save.
sTeP 4. enTer HigH rPm (H=HigH)
The high setting is not needed with this application.

2. Push the "S" button once with zero displayed to
save.
sTeP 5. enTer reTurn rPm
(reT = reTurn)
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.
