VACUUM MOTOR MAINTENANCE

motor maintenance.
2. Vacuum motor should have the brushes
checked every 250 hours. Brushes should be
replaced when they are worn to a length of
10mm or less.

BATTERY MAINTENANCE

: For the best machine performance, keep
batteries charged at all times. Do not let them sit
in a discharged condition.
: Batteries are dangerous! Batteries emit
hydrogen gas and an explosion or fire can result.
Keep sparks and fire away from batteries at all
times.
: Whenever servicing batteries, be sure
to wear protective gloves. Avoid contact with
battery acid at all times!
1. Always follow the battery charging directions
as outlined in the BATTERY CHARGING
section of this manual.
2. Keep battery tops and terminals free from
corrosion. A strong solution of baking soda
and water is the best way to keep the batteries
corrosion free. DO NOT ALLOW THE
BAKING SODA / WATER SOLUTION TO
ENTER THE BATTERY CELLS.
3. Use a wire brush with the baking soda solution
to properly clean the battery posts and
connections.
4. Check battery connections for wear and loose
terminals. Replace if necessary.
