Snap‐on EEWB330A Handspin Wheel Balancer
After the measuring run four readings are possible :
II ‐OP.7 Proceed with the OP program. It is recommended
that the tire be turned over on the rim .OP.7‐II Proceed
with the OP program. It is recommended to shift the tire
on the rim (manual rotation). H0 Optimum condition has
been achieved and cannot be improved. H2 Silent running
cannot be improved. Press STOP (5) to exit. However, it is
possible to readjust the tire relative to the rim to achieve
significant weight minimization (i.e.: smaller balance
weights) without having an adverse effect on silent
running. Depending on the readings, there are several
possibilities for proceeding with the program. These
possibilities are described below. Reading II ‐OP.7(Fig.
5‐37).Turn the tire over on the rim (the left display bars
are rotating).Option1:Turn the tire over on the rim
(normal program) .Read just the wheel according to the
left direction indicator and make a double mark on the
left side of the tire exactly perpendicular to and above
the main shaft. Remove the wheel from the machine.
Turn the tire over on the rim and readjust until the
double mark coincides with the valve. Clamp the wheel
on the balancer and read just it so that the valve is exactly
perpendicular to and above the main shaft. Press the
ENTER key (1) to acquire the valve position. Reading OP.8
appears (Fig.5‐34).Spin the wheel (START). If balancing
optimization (silent running) has been carried out
correctly (according to the program cycle), after the check
run the machine automatically returns to the type of
weight positioning previously selected and indicates the
residual dynamic imbalance on the wheel. Balance the
wheel according to the readings. Both optimization and
balancing are accomplished.
Message E9 means that at least on error occurred
during the optimization cycle. Press the STOP key (5) to
exit the optimization program and repeat optimization
if necessary.
