and remove key.
MAINTENANCE CHECKS
1.Check battery level at delivery and every 10 hours
of operation.
2.Check that all is operating well at delivery and
every 100 hours of operation.
3.Check periodically that waste bins have been
emptied.
4.Check brush condition every 50 hours of
operation. Adjust or replace if necessary.
5.Check belt tension every 50 hours of operation.
Adjust or replace if necessary.
6.Check screws and bolts for tightness every 100
hours of operation.

200 hours of operation. Replace if worn.
BATTERY MAINTENANCE
1.The battery should always be kept clean and dry.
2.Check that the battery and posts are constantly
clean of corrosion.
3.Every 10 hours of operation take off battery cell
covers and check electrolyte level, refilling them
distilled water if necessary. Fill level should be no
more than 1/4”above lead plates.
ATTENTION: Remember that the area where these
operations are done should be well ventilated.
WARNING: Batteries emit hydrogen gas.
Explosion or fire can result. Keep sparks and
open flame away. Keep battery compartment open
