INSTALLATION OF THE “NO STRESS”
DEVICE
The No stress feed rate controller which monitors
the chipping machine wheel’s speed and stops
the feed rolls, if the wheel speed drops below the
set limit value, is available as an option.
The feed rolls continue feed timber, when the
wheel speed increases up to the set value. Thus
the feed rate is adjusted in relation to speed of the
wheel, giving homogenous wood chips, and the
operator can concentrate on feeding the timber.
To install the “No stress” speed control device:
Fit the sensor in the bracket so that the black
tip is approximately 16 mm from the bottom
the bracket. Lock the nuts.
Check through cover slot that the gap between
the screw head and the sensor tip is approxi-
mately 3 mm. The LED will light up, when the
head is at the sensor and the gap is suitable.
If the LED does not light up, adjust the sensor
somewhat closer. See figure Adjustment of No
Stress.

Installation of No Stress
Adjustment of No Stress
Start the tractor’s PTO and adjust the engine
working speed with the manual throttle. Press
the black button on the electrical box for 2-5
seconds. After this, increase the tractor’s revs
by 50-100. The No stress sensor has now
identified the speed. When the speed drops
approximately 10 %, the feed rolls stop
rotating and feeding is interrupted. The feed
rolls start rotating again, as the speed returns
to the set level. This instruction is applicable to
all speeds.
