Calibrate load sensor
The load sensor must be calibrated in case you add
or remove rear weights on the machine. Check and
calibrate load sensor if you add or remove more than
two 29 kg individual weights.
WARNING
Risk of tipping over - The load
sensor may not give correct
information if it is not calibrated
after adding or removing
counterweights.
The load sensor
must be calibrated if you add or
remove two or more AVANT rear
weights (+/- 58 kg).
WARNING
Risk of tipping of the loader and
crushing under lowering load -
Do the calibration on flat, solid
ground, and do not go near the
boom of the loader.
During the
calibration procedure of the load
sensor it is necessary to lift a
heavy load, deliberately causing
the loader to tip forward.
It is not possible to calibrate the
load sensor by lifting the rear of the
loader with a jack or lifting
equipment. For correct adjustment
the rear wheels must be lifted off
the ground using the loader boom
.
To calibrate the load sensor:
1.
Add or remove the counterweights from the
loader.
2.
Remove the engine cover plate and the lower
left side rear cover plate.
3.
Lift something so heavy with the loader that the
rear wheels lift off the ground.
Use the loader boom to lift the rear wheels
slightly off the ground.
Lift only solid objects when doing the
calibration. If you lift soft materials e.g. sand
with bucket, the loader can move if sand starts
to drain from the bucket.
4.
Loosen the bolt of one end of the load sensor
shown in the picture below using two 13 mm
keys. As the two steel strips come in contact
and trigger the switch, tighten the screw.
Keep your hands and feet away from the rear
wheels while doing the calibration.
Do not allow anyone to stay at the driver’s seat
of the loader while adjusting the load sensor -
Accidental movements of the loader can injure!
Keep away from the hot parts of the engine
while doing the calibration.
5.
Use the loader boom to lower the rear wheels
back to the ground.
6.
Check function of the load sensor. Check that
the load sensor is triggered before the rear
wheels lose contact with ground. Re-adjust the
sensor if necessary.
7.
Mount the cover plates. Check that the bolts
that secure the counterweights to the loader
are tightened.
