5.3.4 Correction of inputs after
measurement
If incorrect data and/or incorrect wheel type or balancing
mode were entered for a measuring run:
Enter the correct dimensions, wheel type or
balancing mode, and press the ESC key.
Upon operation of the ESC key the electronic unit
accepts the new input, processes it and then reads out
the corrected measured data in the BALANCING
screen without repetition of the measuring run.
5.3.5 Observation of radial and lateral run-
out of the wheels
Prior to the measuring run check the wheel for
radial and lateral run-out. If considerable run-out
is observed the tire may be incorrectly fitted on
the rim. In this case, the wheel should not be
balanced.
When supplied from our works the machine is
programmed such that the wheel is braked
automatically when the wheel guard is raised (mode of
operation “automatic braking when wheel guard is
raised” set to “yes”).
Observation of the wheel is only possible when this
mode of operation is set to “no” (no braking of wheel
by raising of wheel guard. Changing modes of
operation).
If the mode is set to “no”:
THE WHEEL ROTATES WHEN THE WHEEL
GUARD IS OPEN. MAKE SURE THAT TOOLS OR
THE LIKE DOES NOT BLOCK THE WHEEL.
WEAR SAFETY GOGGLES AND TIGHTLY
FITTING WORKING CLOTHES.
If the wheel clamped on the balancer is to be
checked for visible radial and/or lateral run-out, start
a run - by pressing the START key or by closing
the wheel guard, depending on mode of operation
- prior to the actual measuring run.
Then raise the wheel guard and observe the wheel
for radial and lateral run-out while it slows down.
Finally brake the wheel by operation of the STOP
key.
