Page 9: Safety
ST470E Baggage Tractor SAFETY Observe the following safety precautions. LETHAL DANGER – CARGO USE ONLY The Tractor is designed to tow airport ground support equipment only. Do not exceed the Tractors’ towing capacity. It is dangerous to do so and an accident or damage to the Tractor may result.
Page 10: Warning - Alcohol And Drug Use
ST470E Tractor WARNING – ALCOHOL AND DRUG USE The Tractor must not be accessed or operated by anyone impaired by alcohol or drugs. WARNING – SIZE AND WEIGHT OF TRACTOR The Tractor weighs 4300 kg (9480 lbs). When lifting the Tractor for service and maintenance purposes, always use an Automotive Service Lift/Hoist with a Safe Working Load (SWL) rated above the weight of the Tractor.
Page 11: Warning - Battery - Fire And Health Hazard
ST470E Baggage Tractor DO NOT leave any tools on metal/conductive objects on top of the battery. A short circuit of battery cells may result. WARNING – BATTERY – FIRE AND HEALTH HAZARD During charging the battery will release hydrogen and oxygen. When the hydrogen concentration in the air reaches 4% there is risk of an explosion.
Page 12: Precaution - Personal Protective Equipment
ST470E Tractor PRECAUTION – PERSONAL PROTECTIVE EQUIPMENT When operating, moving, lifting, servicing, repairing, or transporting the Tractor, always wear suitable Personal Protective Equipment (PPE) to prevent crushing of hands, feet, or other body parts. For example, wear protective footwear, safety glasses, hard hat, protective gloves, and high-visibility clothing.
Page 13: Warnings And Precautions - Welding, Grinding, And Cutting
ST470E Baggage Tractor WARNINGS AND PRECAUTIONS – WELDING, GRINDING, AND CUTTING WELDING ARC. A welding arc is bright enough to damage eyesight and cause flash burns. Never look directly at a welding arc with unprotected eyes. Always use an approved welding screen or visor.
Page 14: Introduction
INTRODUCTION The function of the ST470E Tractor is to act as a baggage tractor, towing aircraft ground support equipment (GSE) within the confines of airports. The Tractor is NOT suitable for use on public roads. Multiple GSE can be linked together for towing, up to the towing limit of the Tractor and the regulation limits of the relevant airport/transport authorities.
Page 15: Specification
A hitch at the rear allows multiple carts to be linked together. A hitch at the front allows the Tractor to tow carts while reversing. SPECIFICATION The specification of the ST470E Tractor is given in the following Table. Table 1 ST470E Tractor specification ST470E Tractor...

Page 25: Charging The Battery
ST470E Baggage Tractor CHARGING THE BATTERY The Tractor battery MUST be recharged every day after use. Recharge the Tractor battery as follows: NOTE Leaving a battery in a discharged state for more than 24 hours will reduce battery life and performance.
Page 26: Warning - Battery Gases
ST470E Tractor ➢ Visually check the Main Power Connector and associated cable for damage. If damage is observed, do not attempt to recharge the battery, and REPORT the fault. Guard Access hatch (Power Steering hydraulic oil tank) Main Power Connector Figure 8 –...
Page 27: Checking Battery Electrolyte Level
ST470E Baggage Tractor ➢ Continue charging until the battery is fully charged. Most chargers are designed to self monitor the voltage and adjust the charge rate as the battery reaches full charge, then it will shut off at full charge. To fully charge a battery will take 8 to 12 hours, depending upon the charger.
Page 28: Equalizing Charge
ST470E Tractor Figure 9 - Vent cap : checking the electrolyte level ➢ You MUST use distilled water or de-ionised water to top-up the electrolyte. NEVER use ordinary water. ➢ DO NOT put the distilled water or de-ionised water in a container made from iron or steel. Use either a lead container, or a porcelain/pottery container, or a PVC (plastic) container.
Page 29: Removing The Battery
ST470E Baggage Tractor ➢ Close the battery vent cap. The battery can only be used when the vent cap is closed. Make sure that the vent cap is clean. ➢ Check that all the battery terminal posts are tight and smeared with a small amount of dielectric grease.
Page 30: Battery Storage
ST470E Tractor BATTERY STORAGE If a spare backup battery is required and will not be used for a long period of time, it is recommended that a dry-charged battery is purchased. That is, a battery without any electrolyte present. If a battery contains an electrolyte, and it is placed in storage for a long period, it will slowly self-discharge. The self- discharge will reduce the capacity of the battery (the amount of power it can store), cause counter electrode vulcanisation, and damage the battery’s working life due to time migration hazards.
Page 31: Operation
ST470E Baggage Tractor OPERATION Before starting the Tractor: ➢ Ensure that the EMERGENCY STOP switches are in the open position, and the Gear Lever is in the Neutral position. ➢ Rotate the Start Switch in a clockwise direction to the On position. The Main Contactor (in the Rear Electrical Compartment) connects and the whole Tractor switches On.
Page 32: Storage
➢ Store the Tractor under a suitable cover. Indoor storage is highly recommended. RECEIPT AND PREPARATION FOR FIRST USE On receipt of a new ST470E Tractor, before operating the Tractor for the firsts time, you MUST perform the following: ➢ Make sure that all loose packaging has been removed from the Tractor.

Page 34: Scheduled Maintenance
Scheduled maintenance is limited to the activities specified in the Scheduled Maintenance Table below. The maintenance intervals given are approximate, assume heavy use of the ST470E Tractor, and may be varied by ±10% without adverse effects. Every Tractor should be inspected and serviced based on its own requirements, for example variation in the hours of use and the environment in which it is used.
Page 35 ST470E Baggage Tractor Task Check the windscreen and windows for cracked glass. If glass is cracked, do not use the Tractor until the damaged glass has been replaced. Check that the headlights, indicator lights and rear lights are present and undamaged. Switch ON the ignition and check that all the lights work.
Page 36 ST470E Tractor Task Check that no tools, metal, or conductive items have been left on top of the battery. Perform an “Equalize Charge” on the Battery. Check for water or electrolyte in the steel tray. Remove water and dry tray. Neutralise electrolyte with alkaline water, dilute with water, remove liquid, and dry.
Page 37 ST470E Baggage Tractor Task Check, and if required, adjust the free stroke of the brake pedal and parking brake. Check parking brake cables. Replace if damaged or worn. Adjust if loose. Replace power steering oil. Refer to the Fuel, Lubricants and Consumables section of this manual for details of the power steering oil.

Page 41: Test Equipment
ST470E Baggage Tractor TEST EQUIPMENT The following Test Equipment is used during the failure diagnosis and troubleshooting procedures. ➢ A digital multimeter. The multimeter must have a “diode test” function. The use of a multimeter is ESSENTIAL. ➢ Either a Curtis Model 1313 Handheld Programmer, or a Curtis Model 1314 Laptop Based Programmer.
Page 42 ST470E Tractor Figure 12 - Curtis Model 1314 Laptop Based Programmer For brevity, the electrical failure diagnosis and troubleshooting procedures only refer to the use of a Curtis Model 1313 Handheld Programmer. However, all references to the Curtis Model 1313 Handheld Programmer should be taken to mean either a Curtis Model 1313 Handheld Programmer, or a Curtis Model 1314 Laptop Based Programmer.
Page 43: Troubleshooting And Failure Diagnosis
ST470E Baggage Tractor TROUBLESHOOTING AND FAILURE DIAGNOSIS Troubleshooting and failure diagnosis on the XT470LA Tractor is performed by five methods. The nature of the problem will to a large extent determine which troubleshooting methods to use. ➢ Depending upon the problem, a MIL (Malfunction Indicator Lamp) may be displayed on the Dashboard Instrument Display Screen (Dash Display Screen).
