BATTERIES
The batteries are designed to hold their power for
long periods of time. The lifetime of the batteries is
limited to number of charges the batteries receive. To
get the most life from the batteries, recharge them
immediately when the battery discharge indicator
begins to blink.
FOR SAFETY: When servicing machine, wear
protective gloves when handling batteries or
battery cables. Avoid contact with battery acid.
After every 100 hours of use check for loose battery
connections and clean the surface of the batteries,
including terminals and cable clamps, using a strong
solution of baking soda and water. Brush the solution
sparingly over the battery tops. Do not allow any
baking soda solution to enter the batteries. Use a wire
brush to clean the terminal posts and the cable
connectors. Wipe off all cleaning solution residue.
After cleaning, apply a coating of clear battery post
protectant to the terminals and the cable connectors.
Keep the tops of the batteries clean and dry.
Objects made of metal can potentially short circuit the
batteries. Keep all metallic objects off the batteries.
Replace any worn or damaged wires. Replace any
defective batteries. To dispose of batteries, contact a
battery dealer or your Tennant Service representative.
LEAD ACID BATTERIES
Check the electrolyte level in each battery cell before
and after charging, and after every 25 hours of
operation. Never add acid to the batteries. Add
distilled water only. Always keep the battery caps on,
except when adding water or taking hydrometer
readings.
Using a hydrometer, measure the specific gravity to
determine the charge level and condition of the
batteries. If one or more of the battery cells test lower
than the other battery cells (0.050 or more), the cell is
damaged, shorted, or is near failure. Completely
recharge the batteries and then retest.
04380

S10 SERVICE INFORMATION Maintenance & Repair
S10 331585 (6--07) 11
NOTE: Do not take readings immediately after adding
distilled water. If the water and acid are not thoroughly
mixed, the readings may not be accurate. Check the
hydrometer readings against the following chart to
determine the remaining battery charge level:
SPECIFIC GRAVITY BATTERY
at 27_C(80_F) CHARGE
1.265 100% Charged
1.225 75% Charged
1.190 50% Charged
1.155 25% Charged
1.120 Discharged
NOTE: If the readings are taken when the battery
electrolyte is any temperature other than 27_C(80_
F), the reading must be temperature corrected. Add
or subtract to the specific gravity reading 0.004, 4
points, for each 6_C(10_F) above or below 27_C
(80_F).
CHARGING BATTERIES
The following charging instructions are intended for
battery chargers supplied with the machine.
After every 50 hours check the battery charger cord
for damage.
To prolong the life of the batteries only recharge the
batteries if the machine was used for a total of 30
minutes or more. Do not leave batteries discharged
for lengthy periods.
WARNING: Fire Or Explosion Hazard.
Batteries emit hydrogen gas. Keep sparks and
open flame away. Keep battery compartment open
when charging.
FOR SAFETY: When servicing batteries, wear
protective gloves and eye protection when
handling batteries and battery cables. Avoid
contact with battery acid.
Make sure the charger profile is properly set for the
battery type before charging. Failure to properly set
profile will result in battery damage. To determine the
battery type, see battery label. Contact the battery
supplier if not specified.
To verify the charger profile setting, connect the
charger cord into an electrical receptacle. If the LED
labeled “GEL” is on, the charger is set for Gel
(sealed) batteries. If the LED is off, the charger is set
for Wet/lead acid (flooded) batteries.
To change the charger profile, unplug the charger,
remove the “Charger Profile Selection” panel, and
position the switch towards the proper setting, “GEL”
or “Flooded” .
1. Transport the machine to a well--ventilated area
for charging.
FOR SAFETY: Before leaving or servicing
machine; stop on level surface, set parking brake
(if equipped), and turn off machine.
2. If charging wet (lead acid) batteries check the
fluid level before charging (See BATTERY
MAINTENANCE).
3. Remove the battery compartment covers for
ventilation when charging.

When a fault occurs, the charger will also sound an alarm.
NOTE: The machine will not operate once the battery
charger is connected.
5. Once the batteries are fully charged, the charger
will stop suppling power, but will continue to
monitor the battery voltage. The charger will
restart if the batteries self--discharge.
NOTE: The charger may take up to 30 seconds to
turn off once the charger cord is disconnected. During
this time, the machine will not power up. The charger
cord must also be disconnected for 30 seconds
before the charger can be restarted.
6. Unplug the charger cord from the electrical
receptacle and stow the cord beneath the left
battery.
NOTE: To avoid damaging the charger cord, do not
pul on the cord to unplug the charger from the
electrical receptacle. Use the plug to unplug the cord

increase due to poor alignment. To correct, do
the following:
A. Loosen the bearing flanges as well as the
split coupling bolts.
B. Snug one split coupling bolt.
C. Align the propelling belts. Check for
clearance between the differential and the
locking collar.
NOTE: Minimum clearance between differential and
sheave is 0.3 mm (0.010 in).
D. While holding belt alignment, pull the shaft
away from the differential.
E. Tighten the center and left bearing flanges.
Check for hard rotation of shaft.
F. Tighten the center and left bearing collars.
G. Pull the short differential shaft away from
differential to spread the differential gears.
H. Tighten the right side bearing flange. Tap
bearing before tightening.
I. Tighten the right bearing collar.
J. Check for free spinning of differential.
Loosen the center and right bearing flanges
if it is not spinning freely. Tap and retighten.
K. Align and tighten sprockets. Chains must
be slack to minimize steering effort.
12. Reinstall the access cover, and right side cover,
and bumper.
