Always:
• Keep the battery case and terminals clean and dry and the terminals tight.

• Make sure which terminal is positive (+) and which is negative (–) before
making battery connections, always removing the negative (–) cable first and
reconnecting it last to reduce arcing.

health and safety regulations/codes during handling or disposal.
Always replace the starting battery with the same number and type (e.g., vented,
lead acid, maintenance free) as listed in the specifications section of this document.
Properly dispose of battery in accordance with local environment agency
requirements.
Always use correct handling techniques to lift and move a battery.
5.6 Brush Block and Slip Ring Maintenance
Over time the slip rings can accumulate corrosion which needs to be cleaned off in
order to have normal operation of the alternator. To clean the slip rings and brush
block:
1. Press the generator set's red STOP button on the local display to disable the
generator set. The generator stops immediately and both remote and standby
modes are disabled.
2. Locate and remove the brush block access cover (located on the back side of
the alternator near the cooling fan).
3. Use a Scotch Brite pad and clean off any build up on the slip rings. If
necessary, rotate the alternator by hand while cleaning.
NOTICE
Do not use anything other than a Scotch Brite pad as this will cause
damage to the slip rings and alternator.
