ORBITAL SCRUB HEAD ISOLATORS
FOR SAFETY: Before leaving or servicing machine,
stop on level surface, turn off machine, remove key
and set parking brake if equipped.
Replace the four lower vibration isolators every 500

BATTERIES
FOR SAFETY: Before servicing machine, stop on
level surface, turn off machine, remove key and set
parking brake if equipped.
The lifetime of the batteries depends on their proper
maintenance. To get the most life from the batteries;
S
Do not charge the batteries more than once a day
and only after running the machine for a minimum of
15 minutes.
S
Do not leave the batteries partially discharged for
long period of time.
S
Only charge the batteries in a well-ventilated area to
prevent gas build up. Charge batteries in areas with
ambient temperatures 80
_
F / 27
_
C or less.
S
Allow the charger to complete charging the batteries
before re-using the machine.
S
Maintain the proper electrolyte levels of flooded (wet)
batteries by checking levels weekly.
Your machine is equipped with either flooded (wet)
lead-acid or maintenance-free batteries supplied by
Tennant.
FOR SAFETY: When servicing machine, keep all
metal objects off batteries. Avoid contact with
battery acid.
MAINTENANCE-FREE BATTERIES
Maintenance-free (Sealed AGM) batteries do not
require watering. Cleaning and other routine
maintenance is still required.
FLOODED (WET) LEAD-ACID BATTERIES
The flooded (wet) lead-acid batteries require routine
watering as described below. Check the battery
electrolyte level weekly.
NOTE:
Do Not
check the electrolyte level if the
machine is equipped with the optional battery watering
system. Proceed to the BATTERY WATERING
SYSTEM.
The electrolyte level should be slightly above the
battery plates as shown before charging (Figure 105).
Add distilled water if low. DO NOT OVERFILL. The
electrolyte will expand and may overflow when
charging. After charging, distilled water can be added
up to about 3 mm (0.12 in) below the sight tubes.
