BATTERY CONDITION GAUGE

The battery condition gauge indicates the presentstate of charge of the batteries. The displayshould be on the F mark of the gauge when thebatteries are fully charged. As the batteriesdischarge, the display will move near the E markand start to blink. The batteries should berecharged when the display gets to the 1/4 mark.

When the machine is left overnight with less thana full charge or the battery connectors have beendisconnected and reconnected, the display mayindicate a full charge. It is reading the surfacecharge level -- not the true charge level. Afterrunning the machine a few minutes, the gauge willgive the correct charge level.

NOTE: Do not charge the batteries more oftenthan is necessary. This will prolong the life of thebatteries. Do not allow the batteries to becomefully discharged as this will also damage thebatteries. See BATTERIES in theMAINTENANCE section.

CIRCUIT BREAKERS AND FUSES

Circuit breakers are resetable circuit protectiondevices designed to stop the flow of current in theevent of a circuit overload. Once tripped, circuitbreakers must be manually reset. If the overloadwhich caused the circuit breaker to trip is stillpresent in the circuit, the circuit breaker willcontinue to stop current flow until the overload iscorrected.

Fuses are a one-time circuit protection devicedesigned to stop the flow of current in the event ofa circuit overload. Never substitute higher valuefuses than those specified in this manual.

Most of the circuit breakers are located on thebottom of the instrument panel. Circuit breakersfor the main brush, side brush and cooling motorsare located on the back of the speed controllerpanel. These breakers do not give an indicationthat they have tripped. They must cool beforeresetting. They are also hard to reset -- use thepalm of your hand. The propelling motor fuse islocated in the speed controller box. The coolingfan motor fuse is located next to the fan.

HYDRAULICS

HYDRAULIC FLUID

The quality and condition of the hydraulic fluidplay a very important role in how well the machineoperates. TENNANT’s hydraulic fluid is speciallyselected to meet the needs of TENNANTmachines.

TENNANT’s hydraulic fluids provide a longer lifefor the hydraulic components. There is onerecommended fluid.

TENNANT part no. Fluid Weight

65870 SHP 5/20

If a locally-available hydraulic fluid is used, makesure the specifications match TENNANT hydraulicfluid specifications. Using substitute fluids cancause premature failure of hydraulic components.

European manufactured machines are filled withlocally available hydraulic fluids. Check the labelon the hydraulic fluid reservoir.

ATTENTION! Hydraulic components dependon system hydraulic fluid for internallubrication. Malfunctions, accelerated wear,and damage will result if dirt or othercontaminants enter the hydraulic system.

HYDRAULIC FLUID RESERVOIR

Hydraulic fluid is stored in the hydraulic reservoirsection of the electro-hydraulic power unit. Thereservoir holds 1 gal (3.8 L) of hydraulic fluid. Thereservoir is located under the hood in front of thesolution and recovery tanks.

The fluid level is checked by opening the fillercap. The reservoir is full when the fluid level is1 in (25 mm) from the top or is between the markson the dipstick (if present on earlier stylemachines).

BATTERIES

The batteries provide all of the energy used by themachine. The standard batteries are rated at600 A/h at a 6--hour rate. The maximum batterysize is 15.75 in (400 mm) in width and 19.44 in(495 mm) in length. They require regularmaintenance to keep them operating their best.

When installing new or replacement batteries, besure to set them in the machine with the batterycovers opening from the inside to the outside ofthe machine.

BATTERY INSTALLATION

A. BatteryB. Battery CoverC. Front Machine Frame

Do not allow batteries to remain in dischargedcondition for any length of time.

Do not operate machine if batteries are in poorcondition or have a charge level below 25%,specific gravity below 1.162.

If using a battery not supplied by TENNANT,make sure the battery cables are not longer than18 in (450 mm) or they could rub on the drivemotor studs, wear through the cables and cause adirect short.

Periodically clean the top surface and check forloose connections. Use a strong solution ofbaking soda and water. Brush the solutionsparingly over the battery top. Do not allow anybaking soda solution to enter the battery. Keepthe tops of the batteries clean and dry.

Keep all metallic objects off the top of thebatteries, as they may cause a short circuit.Replace worn or damaged wires.

Check the electrolyte level in each battery cellbefore and after charging the batteries and afterevery 50 hours of operation. Never add acid tobatteries, only distilled water. Do not overfill. Keepvent plugs firmly in place at all times, except whenadding water or taking hydrometer readings.

FOR SAFETY: When Servicing Machine, AvoidContact With Battery Acid.

Use a hydrometer to check the electrolyte specificgravity.

MAINTENANCE

3-13530E MM178 (9--95)

If one or more battery cells tests lower than theother battery cells, (0.050 or more) the cell isdamaged, shorted, or is about to fail.

NOTE: Do not take readings immediately afteradding water--if the water and acid are notthoroughly mixed, the readings may not beaccurate. Check the hydrometer readings againstthe following chart:

SPECIFIC GRAVITYat 80_F (27_C)

BATTERYCONDITION

1.315 100% charged

1.264 75% charged

1.213 50% charged

1.162 25% charged

1.110 Discharged

NOTE: If the readings are taken when the batteryelectrolyte is any temperature other than 80_F(27_C), the reading must be temperaturecorrected.

To determine the corrected specific gravityreading when the temperature of the batteryelectrolyte is other than 80_F (27_C):

Add to the specific gravity reading 0.004,4 points, for each 10_F (6_C) above 80_F(27_C).

Subtract from the specific gravity reading0.004, 4 points, for each 10_F (6_C) below80_F (27_C).

BATTERY CHARGING

The machine batteries are specially made for thismachine application. They are unique in that theyhold their power for long periods of time, but theycan only be recharged a certain number of times.To get the most life from the batteries, chargethem when their charge level is below 25%.

Eight to twelve hours is generally enough time tocharge a discharged set of batteries. If thebatteries are not fully discharged, charge for aperiod of time that is proportionally less than whatis required for a fully discharged set of batteries,ie: half discharged heavy duty batteries needseven to eight hours of charging time.

Do not expose the battery charger to water. Donot touch uninsulated battery terminals orunnecessarily expose any portion of your body tothe batteries when making electrical connections.

ELECTRIC MOTORS

The electric motors are repairable.

Blow out the dust and inspect the motor brushesin the vacuum fan motor after every 400 hours ofoperation and in all the other motors after every1000 hours of operation.

If the brushes are broken, cracked, chipped, orhave been worn to less than 0.62 in (15 mm) inlength on the short side on the propelling motor,or 0.38 in (10 mm) in length on the short side onthe main and side brush drive, cooling fan orvacuum fan motors, replace them. Remember toalways replace brushes in sets.

If the commutator is worn or rough, the motorarmature should be removed and serviced.

PROPELLING CIRCUIT

The propelling circuit is made up of contactorsand an SCR controller. They control the forwardand reverse speed of the machine and arelocated in the controller panel. The circuit is notuser serviceable -- only trained personnel shouldbe allowed to work on it. Do not steam clean orspray the panel with water as it may damage theelectrical system.

Inside the controller panel are two cooling fan inletfilters. Remove, clean, and reinstall the filters afterevery 200 hours of operation.

The SCR controller is a solid state speed controldevice. It supplies the drive motor with a smoothflow of energy. It does this by sending the motorshort bursts or pulses of energy that through themachine we feel is continuous. The directionalcontrol pedal controls the number of pulses. Theharder the pedal is pressed, the greater numberof pulses, the faster the machine travels. Thepulsing is where the whine of the propellingsystem comes from. The SCR is the heart of thecontroller. It is a high speed, high current capacityswitch.

BRAKES AND TIRES

BRAKES

The foot brake and the parking brake operate thelinkage which controls the brakes on the rearwheels. Use them daily to avoid corrosion and dirtbuildup on the brake shoes.

The foot brake needs no regular adjustment. Theparking brake should be adjusted after every 200hours of operation or whenever it becomes veryeasy to engage it.

To adjust the parking brake, turn the knurled knobon the end of the parking brake clockwise. If theknob adjustment is inadequate, remove the clevispin from each brake assembly, turn the clevisends an equal amount, reconnect the clevis pins,and readjust the parking brake knob.
