8.0Troubleshooting
Symptom Possible Problem Correction
Accuracy Incorrect bucket position. Bucket must be rolled back
completly before each lift.
Incorrect calibration number. Most 100 applications will
have a Cal. No of 1.0-4.0
make sure decimal point is
in correct place. To make
scale reading heavier raise
the Cal No. To make the
scale read lighter lower the
Cal No.
Incorrect lifting method. Model 100: Weights can
vary depending upon lift
speed. Choose a lifting
speed and weigh the same
each time.
Incorrect load positioning With forks and grapples the
load must be centered and
as close to the machine as
possible.
Incorrect weighing units selected With bucket on ground
display shows 0.00 unit
is set to weigh in tons. If
display shows 0 unit is
set to weigh in pounds.
Incorrect channel selected Be sure correct channel
is selected for bucket or
attachment used. If only 1
bucket or attachment is
used set all 5 channels to
correct Cal. No.
Incorrect load sensor installation Be sure the load sensor
is installed in the pressure
side of the lift cylinder not
the return. This will cause
the scale reading to be very
incosistant and may display
a negative number with a
load after the bucket was
set to zero. This can also
be noticed by the need for
a large Cal. No. > 5.0.
