Leveling the Balance
(not for models PGB610-2 and PGB6100-1)
Level the balance any time you set it up in a new
location. Use only the 2 front feet of the balance
for leveling.
Turn the 2 rear feet until they are in position
(only on models PGB3100-2 and PGB1500-2)
Turn the 2 front feet as shown here in the illustration
until the air bubble is centered in the level indicator
> In most cases, this will require several adjustment
steps
Anti-theft Locking Device
To protect against theft, use the mounting lug on
the rear panel of the balance.
Secure the balance at the place of installation,
for example with a chain or a lock
