1 INTENDED USE
For models ER220, ER160 and ER165, after manually entering rim data (diameter,
distance and width) and having started wheel spin, the stop procedure becomes
automatic until the required weight is found.
Wheel spin with wheel balancer mod. ER200 and ER150 is on the other hand manual,
consequently stop is also manual by means of the pedal provided.
Numerous reasons exist for wheel unbalance, but this is usually caused by a non-
symmetric distribution of the rim fabrication materials, above all of the tyre with respect
to the rotation axis and equatorial plane of the wheel, to imperfect mutual rim-tyre
positioning and to incorrect wheel centring on the hub.
The purpose of this equipment is to cancel out, or at least reduce to within acceptable
limits, the vibrations of the wheel that cause driving problems and damage mechanical
parts. The equipment is suitable for all types of vehicle wheels and light commercial
vehicles.
This aim can be achieved by fitting counterweights of suitable size and in specific
positions to wheels that are not correctly balanced.
A wheel can be considered completely balanced only once it is dynamically balanced, as
this also ensures dynamic balancing.
The specifications are indicated in the "TECHNICAL DETAILS" paragraph (para. 3.4 on
page 7). As well as standard procedures, 4 options exist for light alloy wheels and the
ALU/Special function, which enables the two counterweights to be fitted in the most
appropriate positions.
Counterweight positioning is also reduced to a simple procedure. If, when balancing
spokes alloy wheels, the external weight becomes visible, a special procedure exists
(weights hidden behind spokes mode), which splits the weight in two and positions these
behind two spokes. Autotest, auto-calibration and guided calibration of the measuring
heads make it possible to always work with perfectly functional machines.
