(Every 600 Hours)
Call your Authorized NSS Distributor / Service
Station to have the following services performed.
Verify that all daily, weekly, monthly and quarterly
maintenance has been performed.
Inspect Brush Motor carbon brushes for wear.
 Using compressed air, blow the accumulated carbon
brush dust out of the motor.
 Replace carbon brush when they measure ½"
[12.7mm] or less in length.
 Failure to replace carbon brushes will cause poor
machine performance and possible motor damage.
Check the condition of the batteries.
 A battery may be checked using a Hydrometer to
check the specific gravity (strength) of the acid in
each cell. Variations in readings occur due to the
chemical reaction taking place during use.
 Always check the specific gravity when the battery is
fully charged.
 Replace batteries as needed.
Battery Installation:
 Turn off all switches. Disconnect battery pack from
the machine.
 ALWAYS wear eye protection, rubber gloves and
protective clothing to avoid contact with battery acid
when installing batteries. See Battery Warnings on

nuts located in each corner inside the battery

Move them out of the way to install the Batteries.
 Batteries are heavy – ALWAYS use two people to
