Charging The Vehicle; Electric Motor Maintenance - Blue Bird TC/2000 Owner's Manual

CHARGING THE VEHICLE

Following are the steps for charging the lead acid battery-powered vehicle.
1. Pull the vehicle near the charging station. Position the vehicle so that the right rear side panel is near
the charging station.
2. Shut down the vehicle in accordance with the procedures listed above but do not lock the vehicle yet.
3. Locate the on-vehicle charge receptacle. It is near the right side rear panel past the two battery rack
panels. The receptacle is rectangular in shape with a key lock.
4. Verify that the charger you plan to use has been approved for the bus and has the correct Meltric
connector.
5. Open the battery cable storage cabinet, which is mounted on the wall at the charging station, and
unwind enough cable to reach the vehicle charging receptacle.
6. Connect the charging cable to the vehicle receptacle by inserting the pins on each side of the cable
connector into slots on the vehicle receptacle and pushing down on the handle until the connector
snaps into place.
7. Charging the Traction battery packs requires 8-10 hours depending on state of charge at beginning of
charge cycle.
8. The charger will automatically shut itself off when the charge cycle is complete.

debris. Lubricate units per instructions and instruction plate on unit.
CAUTION: Excessive lubrication may damage unit. Do not over grease.
WARNING: Disconnect all power sources to the unit and discharge all parts that may retain an electrical
charge before attempting any maintenance or repair.
Screens and covers must be maintained in place
when unit is in operation. Motors for use in hazard-
ous locations - Class I & II installation: Repairs of these
motors must be made by the manufacturer or autho-
rized service station approved by the manufacturer

LUBRICATION INSTRUCTIONS
Power Steering / Propulsion Motor Cooling Pump
& Motor
Some small motors have sealed-for-life bearings
which require no relubrication. Regreaseable bearings
are shipped with a high quality, wide temperature
range grease in the bearings.
Motors can be regreased by stopping the motor,
removing the drain plug and pumping new grease into
the fill hole. Run motor with drain plug removed until
excess grease has been discharged (minimum 10 min-
utes). Stop motor and replace drain plug.
Units that operate at speeds greater than 1800 RPM
should be lubricated on a more frequent maintenance
schedule depending on duty cycle. Use a low pres-
sure grease gun and avoid over greasing.
