MAINTENANCE INSTRUCTIONS M AINTENANCE S CHEDULE Safe trouble-free operation of your electric vehicle depends on regular and proper preventive maintenance. The following chart is a guide for servicing your Pack Mule electric vehicle.
MAINTENANCE INSTRUCTIONS R OUTINE M AINTENANCE Before performing any maintenance or repair work, isolate the batteries from the motor and electronics by opening the circuit breaker in (Figure 12). Simply push the red push button until the red side lever fully opens (Figure 13). To close the circuit breaker, simply push the red side lever to its original closed position.
MAINTENANCE INSTRUCTIONS 4) 5) During shipment or prolonged storage the electrolyte levels may fall below the separator protector. Only after a complete discharge and charge cycle, check and keep electrolyte level above separator and 1/8” (3.175mm) below vent well. Add approved water only when required and never add acid. Keep battery top clean, dry and vent caps tightly in place. 6) Keep open flame and metal objects away from battery top.
MAINTENANCE INSTRUCTIONS L UBRICATION L IFTING THE V EHICLE WARNING To prevent possible injury or death resulting from a vehicle falling from a jack, be sure the vehicle is on a firm and level surface. Never go beneath a vehicle while it is supported by a crane or jack. Use jack stands and test the stability of the vehicle. Always place chocks in front and behind the wheels not being raised.
MAINTENANCE INSTRUCTIONS Rear Axle: Check fluid level in the rear axle per the recommended maintenance schedule. The rear axle is provided with a fluid level check/fill plug (Figure 18) located at the bottom of the differential. With the vehicle on level ground, clean the area around the check/fill plug and remove plug. The correct fluid level is just below the bottom of the threaded hole. If fluid levels are low, add as required until it starts to seep from the hole. Install the check/fill plug.
MAINTENANCE INSTRUCTIONS T IRES AND W HEELS The PCT series has an 5,000 lb tow capacity. The transaxle has a five bolt pattern for the wheels.

COMPONENTS - ELECTRICAL B ASIC E LECTRICAL C OMPONENTS Your Pack Mule electric vehicle is purposely designed around the “Keep it Simple” principal. Our philosophy at Wesley International is to engineer products with only the critical components necessary to meet the demanding industrial environment, cutting out any unnecessary “bells and whistles” which only increase ownership costs.
COMPONENTS - ELECTRICAL O NBOARD B ATTERY C HARGER This section assumes your unit has the standard onboard Delta-Q Battery Charger (Figure 20). The onboard charger is air cooled, eliminating any moving parts for increased reliability and life span. Because of this, the mounting location has been designed to optimize air flow and it is important that this air flow is not inhibited in any way. Regularly check the cooling fins to ensure they are free of dirt, dust, or other contaminants.
COMPONENTS - ELECTRICAL The optional charger Single-LED display, if included, would be located on the front panel, near the key-switch. LED Color Indication (following “Power-On Self Test”) Green 1) 2) 3) Solid: Charging complete. Charger in Maintenance Mode. Flashing: Short: <80% Charge Long: >80% Charge Amber Flashing: Reduced power mode: Low AC voltage or High internal charger temperature. Red Flashing: Charger error. Reset charger power and refer to trouble shooting instructions.
COMPONENTS - ELECTRICAL STANDARD M OTOR All Pack mule electric vehicles are equipped with Separately Excited DC motors. The motor Field and Armature are completely separate and are energized independently by the motor controller. (See Figure 21) F IGURE 21 C ONTROLLER The PMT Series electric vehicle is equipped with a Curtis separately excited (Sep Ex) motor speed controller. (See Figure 22) These programmable controllers are simple to install, efficient, and cost effective.
COMPONENTS – ELECTRICAL Your Pack Mule vehicle should be equipped with one of the following Curtis motor controller models: 36 Volt DC: 48 Volt DC: Curtis Model 1243 or 1268 Curtis Model 1268 If your vehicle is equipped with an older Sevcon motor controller, please contact Wesley International for a copy of the Sevcon controller manual, or download a copy from www.packmule.com.
COMPONENTS - ELECTRICAL Controller Wiring: Typical Controller wiring configuration of PC series vehicles. The interlock switch is a seat switch or foot switch and there is no emergency reverse. F IGURE 2 Diagnostics and Troubleshooting: The controller provides diagnostics information to assist technicians in troubleshooting drive system problems.

TRANSAXLE TROUBLESHOOTING PROBLEM DIAGNOSIS Most drive axle problems fall into the categories of noise, vibration, leaks and failure to transmit power. Problem diagnosis normally begins with the customer’s complaint, which should include an exact description of the type of noise or vibration and when it occurs. This is followed up by a road test over various types of road surfaces through the speeds where the complaint occurs.
