 It is the responsibility of the owner of this vehicle to train operators to ensure that they understand the operating
characteristics of this vehicle, including training in vehicle stability, and obey the following safety rules and
guidelines. Owner shall comply with OSHA and ANSI/ITSDF B56.8 & B56.9 Standards for vehicle use, safety rules,
operator training and certification. Do not drive this vehicle unless you are a qualified operator.
 Do not drive this vehicle under the influence of drugs or alcohol.
 Do not drive this vehicle on public roads and highways. This vehicle is designed to be driven in buildings.
 The electrical system of this vehicle will make sparks which can ignite inflammable materials. Never use the vehicle
in hazardous areas where there are inflammable materials, explosive dust or fumes in the air.
 Have your vehicle inspected regularly by trained personnel, and cease operation if a malfunction occurs.
 Do not open battery compartment to prevent battery explosion, acid splashing, severe damage to eyes or skin.
 Do not open motor compartment. Keep clear from moving, rotating(wheels, sheaves, etc) or lifting parts.
 Never carry more passengers than number allowed for this vehicle. Wait until all occupants are seated and holding on
before moving. Always keep all body parts inside vehicle. Keep both hands on steering wheel.
 Do not exceed the vehicle cargo load capacity and gross trailing weight capacity, rated for flat hard even surface.
Different operating conditions such as loose terrain or ramps reduce vehicle capacity.
 Avoid loose, unbalanced or top-heavy loads to keep a good stability and prevent overturn. Do not load cargo that can
fall off the vehicle. Do not carry cargo that is longer, wider or higher than this vehicle.
 Always depress slowly the accelerator for smooth acceleration. Avoid stunt driving or horseplay.
 Avoid sharp turns, always slow down before turning, to prevent vehicle overturn or trailer jack knife. Vehicle is more
sensitive to overturn and jack knife when traveling on inclines or when carrying a heavy load.
 Always drive straight up and down the face of an incline, never across the face, to prevent overturn and trailer jack
knife. Drive slower and start applying brakes sooner on inclines to adjust for longer stopping distance.
 Use extra care and drive slowly in reverse, in congested areas or on wet or slippery ground.
 Keep to the right under normal conditions. Maintain a safe distance from all objects.
 Slow down and sound the horn when approaching a corner or other blind intersections.
 Before leaving the vehicle, park on a level ground flat surface, turn off all switches, set the forward/reverse switch to
neutral, set the parking brake, remove the key. Do not park the vehicle on an incline.
 Before battery charging, park the vehicle in a well ventilated area set for. Do not operate it when charging. To
interrupt a charging cycle, disconnect the AC plug; disconnecting the DC plug or a battery terminal, or operating the
vehicle, could damage the charger and produce a spark, battery explosion and acid splashing.
 Use another driver to steer this vehicle while it is towed. Be sure the driver uses brakes when you slow or stop the
towing vehicle. Do not exceed 5 MPH or carry any passenger while towing this vehicle.

AFTER TURNING ON KEYSWITCH
Check safety devices: seat switch, reverse alarm, motion beeper, strobe light, and all other safety devices.
BATTERIES
Never open the battery compartment unless you have received proper training for battery maintenance.
Batteries emit explosive hydrogen gas that can be ignited by a spark or loose terminal. Battery acid causes severe damage to
eyes or skin. Flush the contaminated area immediately with water. Park the vehicle in a well ventilated area for battery
charging. Most battery chargers come with an electronic control that starts when the charger is plugged and stop when the
battery is fully charged. To interrupt the charging cycle, disconnect the AC-plug, do not disconnect the DC plug.
BATTERY DISCHARGE INDICATOR
The green light moves from right to left as batteries are being discharged. When the green light is at the last position on the
left the batteries must be recharged. A flashing light warns the operator that further discharge will damage batteries. See
HOBBS indicator instructions.
EMERGENCY SAFETY DEVICE

SAFETY WARNINGS FOR SERVICE TECHNICIANS
FAILURE TO OBEY THE FOLLOWING SAFETY RULES MAIN RESULT IN SEVERE INJURY.
Owner shall comply with OSHA and ANSI/ITSDF B56.8 & B56.9 Standards for vehicle maintenance.
Only qualified and authorized personnel shall be permitted to maintain, repair, adjust and inspect
carriers, vehicles, tractors, and batteries.
Before any maintenance work, park the vehicle on flat level surface, turn off all switches, remove key,
lift wheels off the ground and secure with jack stands of adequate capacity. Don’t connect charger.
Keep clear from moving parts such as tires, sheaves and motor.
Follow the maintenance instructions applicable to the type of repair, maintenance, or service.
Always wear a face shield and gloves when working around batteries.
Before opening the battery compartment, disconnect the charger, turn off all switches and remove the
key. Batteries emit highly explosive gases which greatly increase when charging; do not disturb
connections or produce sparks around batteries to avoid a battery explosion and acid splashing. Battery
acid causes severe damage to eyes or skin. Flush contaminated area immediately with water.
Use insulated tools to avoid sparks that can cause battery explosion and acid splashing.
Use two counteracting tools, double-wrench technique, when disconnecting or tightening terminals on
the battery and the speed controller to avoid cracking the terminal or battery post welds.
Before cleaning or replacing a battery, charger, speed controller, contactor, relay, diode, or any other
component in the power circuit, always disconnect the charger, turn off all switches, remove the key,
wear a face shield and gloves, identify battery polarity and disconnect battery leads, discharge the
capacitor in the controller with a 10 ohms, 25 W resistor for a few seconds across B+ and B-.
After cleaning, the power must not be reapplied until terminal areas are thoroughly dry.
On EE-Rated vehicles make sure that the control box is sealed, the static strap makes good contact with
the ground, the motor is sealed by bands, the cable protectors are properly installed.
Keep cables and wires clear from mechanical and rubbing action. Make sure that cable insulation is
free from cutting or visible damage. Make sure that EE-Rated cable protectors are properly installed.
Before replacing a fuse or circuit breaker, identify the cause of failure and repair.
Programmable controllers must be programmed using the parameter settings in this service manual,
before connecting the motor, to avoid sudden vehicle movement and accident.

Maintenance
- 9 -
Do not try to increase motor speed by changing parameter settings in the speed controller; it can cause
accident and severe damage to the motor.
SEPEX speed controls are protected by a diode in the power circuit to filter inductive loads in the event
of a sudden power interrupt. Some speed controllers require a diode to filter inductive loads on the KSI
input. Removing the diodes will cause the speed control failure.
Before resuming maintenance operations, inspect safety warnings stickers and replace any if damage is
found and part of the text can’t be read.
Check decals and labels, see “DECAL AND LABELS” page.

BATTERY MAINTENANCE
! WARNING !
 It is the responsibility of the owner of this vehicle to ensure that the service technicians are
properly trained, read and obey the safety rules and guidelines in this manual (ANSI B56).
 Maintenance operations must be made by properly trained service technicians only.
 Before any maintenance work, park the vehicle on a flat level surface, turn off all the
switches, set to neutral, remove the key, lift the wheels off the ground and secure with jack
stands of adequate capacity.
 Keep charger disconnected while doing any maintenance work.
 Always wear a face shield and scarf when working around batteries.
 Battery emits highly explosive gases; do not produce sparks to avoid battery explosion and
acid splashing. Battery acid causes severe damage to eyes or skin. Flush contaminated area
immediately with water.
 Use insulated tools to avoid sparks that can cause battery explosion and acid splashing.
 Use two counteracting tools, double-wrench technique, when disconnecting or tightening
battery posts.
 Before cleaning or replacing a battery, discharge the capacitor in the controller with a 10
ohms, 25 W resistor for a few seconds across B+ and B-, identify battery polarity and
disconnect battery leads.
 After cleaning, the power must not be reapplied until terminal areas are thoroughly dry.
BATTERY LEADS AND CONNECTORS
Check for loose connections, damaged cables, acid spill, loose terminal posts, quarterly.
BATTERY POST CORROSION
If corrosion is present on battery posts, remove the cable connectors, use a wire brush to remove
particles, and then clean them with a cloth that has been moistened with ammonia.
ELECTROLYTE LEVEL
Does not apply to sealed battery.
 Disconnect battery connectors on roll-out or lift-out installations.
 Make sure the battery roll-out tray is provided with stops before rolling out.
 Fill with distilled water.
 Daily charged batteries normally require watering once a week. Under watering leads to a
shortened battery life. Over watering leads to battery corrosion. Be careful not to overfill any cell to
avoid electrolyte to be forced out while charging.
 Fill each cell to plate level with distillated or de-ionized water, before battery charging. When the
battery is charged, the fluid expands and can seep out if overfilled. Refill each cell after full charge,
when the fluid has expanded to its maximum level.
 Reinstall battery caps before charging.

Maintenance
- 19 -
BATTERY MOUNTING
A loose battery increases damaging effects of vibrations and is more prone to short out.
BATTERY DISCHARGE LIMIT
Discharging below a 20% state of charge cuts down the battery life and the number of cycles available.
At 20% state of charge, specific gravity of 6V battery should be 1180; and 1220 for industrial battery.
CHARGING AREA
 Always charge battery in a well ventilated area set for and approved for charging.
 Never leave a charger connected for more than 20 hours.
FREQUENCY OF CHARGE
 When a battery is discharged to its 20% state of charge, it is best to charge immediately.
 Batteries require a low current equalization charge (min 4 hours) at least every week, to equalize
battery cells, improve battery performance and life in number of cycles.
 Never leave a charger connected for more than 20 hours.
STORAGE
 Keep the battery from getting cold, it would loose its capacity.
 Let the battery warm up before charging.
 Charge batteries in “stored” vehicles every month.
DEFECTIVE BATTERY
Check specific gravity of each cell; if a cell is shorted, voltage drop may occur only when there is
current.
