FIG. 25
3. When finished scrubbing, drain and rinse solution
tank and clean ES filter (See DRAINING TANKS).
WHILE OPERATING MACHINE
FOR SAFETY: When using machine, go slow on
inclines and slippery surfaces.
1. Observe amount of solution flow on floor. If
solution flow adjustment is needed, see MACHINE
ADJUSTMENTS.
2. Periodically check for foam buildup in recovery
tank (look through clear lid). If excessive foam is
developing, pour a recommended foam control
solution into recovery tank.
ATTENTION: Do not allow foam to enter the float
shut-off screen, vacuum motor damage will result.
Foam will not activate the float shut-off screen.

OPERATION
Tennant 5100 (06--05) 13
3. Always operate with caution when scrubbing
around walls or obstacles.
4. If squeegee leaves streaks, raise and wipe blades
with a cloth. Pre-sweep area to prevent streaking.
If squeegee adjustment is necessary, see
MACHINE ADJUSTMENTS.
5. Overlap each pass by 50mm (2 in).
6. Change or turn over pads when dirty.
7. Stay clear of floor obstructions, such as electrical
plates or grates, they will destroy pads.
8. During brief stops, you do not have to turn off any
switches, the brushes and solution flow will
automatically stop when triggers are released.
9. Periodically check battery meter discharge level.
When needle drops to the red zone, recharge
batteries.
ATTENTION: Do not operate machine with battery
meter in red zone, battery damage will result.
WARNING: Fire Or Explosion Hazard. Do Not
Pick Up Flammable Materials Or Reactive Metals.
10. On last scrubbing pass, turn off solution switch
just prior to stopping machine. This will allow total
recovery pick up.
11. When solution tank runs dry, drain recovery tank
(See DRAINING TANKS).
OPERATING ACCESSORY TOOLS (OPTIONAL)
1. Attach accessory solution hose to quick coupler.
2. Disconnect squeegee hose from inlet tube and
replace with accessory vacuum hose.
3. Connect hoses to wand.
4. Turn on key, wand pump and vacuum switches
(Figure 26).
FIG. 26

Check motor(s) for carbon brush wear, replace
brushes if worn to a length of 10mm (0.38 in) or less.
Contact your Authorized Service Center for carbon
brush inspection.
FOR SAFETY: When servicing machine all repairs
must be performed by a qualified service person.
BATTERY MAINTENANCE
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 machine, wear
protective gloves and eye protection when
handling batteries or battery cables. Avoid contact
with battery acid.
1. Always follow proper charging instructions (See
BATTERY CHARGING).
2. Check fluid level (A) in each battery cell. The fluid
level should be 1 cm (3/8 in.) from the bottom of
sight tubes after charging. Add distilled water if
needed. DO NOT OVERFILL. Overfilled batteries
can overflow during charging due to fluid
expansion (Figure 39).

FIG. 39
3. After charging batteries, measure the specific
gravity in each battery cell using a hydrometer
(Figure 40). This will determine the charge level
and condition of the batteries. If one or more of
the battery cells test lower than the other battery
cell (0.050 or more), the cell is damaged,
shortened, or is about to fail.
NOTE: Do not take reading immediately after adding
distilled water. The water and acid must be thoroughly
mixed in order for accurate reading.

NOTE: Add or subtract 0.004 gravity reading for each
6_C(10_F) above or below 27_C(80_F).
4. Keep battery tops and terminals clean and dry.
a. Mix a strong solution of baking soda and water
(Figure 41).
FIG. 41
b. Brush solution sparingly over battery tops,
terminal and cable connectors.
NOTE: Do not allow baking soda solution to enter
battery cells.

c. Use wire brush to clean terminal post and
cable connections.
d. After cleaning, apply a coating of clear battery
post protectant to terminals and cable
connections.
5. Check for loose or worn cables. Replace if worn.
TRANSPORTING MACHINE
When transporting machine by use of trailer or truck,
be certain to follow tie--down procedures below:
FOR SAFETY: When using machine, go slow on
inclines and slippery surfaces.
1. Remove squeegee from machine and raise scrub
head. Leave pad or brush installed.
2. Load machine using a recommended loading
ramp.
3. Position front of machine up against front of trailer
or truck. Once machine is positioned, lower brush
head.
4. Place a block behind the wheels.
5. Place tie--down straps over top of machine and
secure straps to floor. It may be necessary to
install tie--down brackets to the floor of your trailer
or truck.
FOR SAFETY: When transporting machine, use a
recommended ramp when loading/unloading
into/off truck or trailer, use tie--down straps to
secure machine to truck or trailer.
STORING MACHINE
1. Before storing machine, be certain to rinse tanks
and drain machine of all water.
2. Store machine in a dry area with squeegee
removed and scrub head in the raised position.
3. Remove recovery tank lid to promote air
circulation.
ATTENTION: If storing machine in freezing
temperatures, be certain to drain machine of all
water. Damage due to freezing temperatures is not
covered by warranty.
WARNING: Do Not Use Outdoors. Do Not
Expose To Rain. Store Indoors.
