IMPORTANT INFORMATION FOR MACHINES WITH SERIALNUMBER DATE CODES PRIOR TO DC1006 (October, 2006)Potential rolling hazard may exist when transporting the machine on a ramp or incline with keyturned to the “off” position. The machine could roll at an undesirable speed creating the risk forpotential injury or property damage.

To ensure operator safety and to prevent potential property damage,Tennant Company mandatesthat the existing control box assembly be replaced with the Control Box Kit (p/n 9003250). For moreinformation, refer to Technical Service Bulletin # 130. To determine if the machine in question hasbeen updated with the new Control Box Kit, refer to the picture below.

CONTROL BOX ASSEMBLY

If the Brake Relay (CR2) is present in theControl Box, the machine has already beenupdated and no further action is required.If the Brake Relay (CR2) is NOT present inthe Control Box, follow the instructions inTechnical Service Bulletin # 130.

CHARGING BATTERIES

ATTENTION: To prolong the life of the batteriesonly recharge the batteries if the machine wasused for a total of 30 minutes or more. Do not leavebatteries discharged for lengthy periods.

WARNING: Fire Or Explosion Hazard.Batteries Emit Hydrogen Gas. Keep Sparks AndOpen Flame Away. Keep Battery CompartmentOpen When Charging.

FOR SAFETY: When servicing batteries, wearprotective gloves and eye protection whenhandling batteries and battery cables. Avoidcontact with battery acid.

BATTERY CHARGER SPECIFICATIONS:

S CHARGER TYPE:-- FOR SEALED (Gel) BATTERIES-- FOR WET (Lead acid) BATTERIES

S FOR DEEP CYCLE BATTERY CHARGING

ON--BOARD BATTERY CHARGER SETTINGS:

If your machine is equipped with the on--board charger,the charger settings must be set for your battery typebefore charging. Failure to properly set will result inbattery damage.

To determine your battery type, see battery label.Contact your battery supplier if not specified.

To verify what the charger is currently for, connect thecharger cord into an electrical receptacle. The chargerwill display a sequence of codes. One of the codes willeither read “GEL” or “Acd” (Figure 40).

GEL = Set for sealed/maintenance free batteriesAcd = Set for wet/lead acid batteries

FIG. 40

To change the setting, unplug the charger, peel up thecorner of the display label and set the switchesaccordingly (Fig. 41). The charger cord must beunplugged when resetting.

FIG. 41

USING THE ON--BOARD BATTERY CHARGER

IMPORTANT: Before charging, make sure that thecharger setting is properly set for your battery type(See ON--BOARD CHARGER SETTINGS).

1. Transport the machine to a well--ventilated area.

2. Park the machine on a flat, dry surface. Turn thekey off and set the parking brake, if equipped.

3. If charging wet (lead acid) batteries check the fluidlevel before charging (See BATTERYMAINTENANCE).

4. Prop up the recovery tank for ventilation(Figure 42).

FIG. 42

5. Connect the charger’s AC power supply cord into aproperly grounded receptacle (Figure 43).

NOTE: The machine will not operate when charging.

A = Charging currentU = Battery Voltageh = Charging timeC = Charging ampere--hours [Ah]E = Energy used [Kwh]“GEL” or “Acd” = Battery type the charger iscurrently set for. Before charging make sureyour battery type matches the display:GEL=Sealed, Acd=WET (lead acid). To changesetting, see ON--BOARD CHARGERSETTINGS.

Press the arrow button to review the codes.

FIG. 44

7. Once the charging cycle begins, the indicator lightswill progress from red, yellow to green. When thegreen indicator light comes on, the charging cycleis done. Unplug the charger cord.

If the charger detects a problem, the charger willdisplay an error code (See ON--BOARD BATTERYCHARGER ERROR CODES).

USING AN OFF--BOARD BATTERY CHARGER(OPTION)

1. Transport the machine to a well--ventilated area.

2. Park the machine on a flat, dry surface. Turn thekey off and set the parking brake, if equipped.

3. If charging wet (lead acid) batteries, check the fluidlevel before charging (See BATTERYMAINTENANCE).

4. Prop up the recovery tank for ventilation(Figure 45).

FIG. 45

5. Connect the charger’s DC cord into the machine’sbattery receptacle (Figure 46).

6. Connect the charger’s AC power supply cord into aproperly grounded receptacle (Figure 46).

FIG. 46

7. The supplied charger will automatically begincharging and shut off when fully charged.

NOTE: The machine will not operate when charging.

ATTENTION: Do not disconnect the charger’s DCcord from the machine’s receptacle when thecharger is operating. Arcing may result. If thecharger must be interrupted during charging,disconnect the AC power supply cord first.
