1. TMX CLARK TMX Service Overview By: Mark Dyster 2005 National Sales Meeting

2. TMX Recognizing the benefit of AC technology, CLARK developed the TMX with 100% AC MOTORS. 2005 National Sales Meeting

3. TMX TMX Induction Motors • No brushes to change or commutator to turn….ever • Routine brush changes are eliminated. • No need to pull the motor to turn and under-cut the commutator. • Much less likely to burn-out motor during a stall (Brushes were hot spots on DC motors.) 2005 National Sales Meeting

4. TMX TMX Induction Motors- Continued • All TMX Motors are Fully Enclosed • Keeps out dust and contaminates. • Wet environment is not an issue. • Better suited for food processing or outdoor use. • Same motor in UL “E” and “EE” models. • But…………………… 2005 National Sales Meeting

5. TMX Must avoid spray washing with high pressure hose. 2005 National Sales Meeting

6. TMX TMX Induction Motors- Continued • Standard Thermistor • All motors are equipped with a thermistor which constantly monitors temperature. Should the temperature approach the thermal limit, the control cuts back current. • Once motor temperature decreases, full power is automatically restored. • Some competitors offer thermal switches. When activated, truck performance decreases drastically. Operators typically park the truck and wait for it to cool. 2005 National Sales Meeting

7. TMX TMX Induction Motors- Continued • Pump Motor Thermal Cut-back • Full control current up to ADJUSTMENT #4 temperature. • ADJUSTMENT #4 is set at 130°C. DO NOT CHANGE. • Proportional cutback from ADJUSTMENT #4 to MOTOR SHUTDOWN temperature. • MOTOR SHUTDOWN is set at 145°C. DO NOT CHANGE. • Above MOTOR SHUTDOWN temperature you have steering only. • Icon on dash and fault code illuminate once ADJUSTMENT #4 temperature is reached. 2005 National Sales Meeting

8. TMX TMX Induction Motors- Continued • Traction Motor Thermal Cut-back • Full control current up to ADJUSTMENT #4 temperature. • ADJUSTMENT #4 is set at 130°C. DO NOT CHANGE. • Control current is reduced to ½ MAX from ADJUSTMENT #4 to MOTOR SHUTDOWN temperature. • MOTOR SHUTDOWN is set at 145°C. DO NOT CHANGE. • Above MOTOR SHUTDOWN temperature traction is disabled. • Icon on dash and fault code illuminate once ADJUSTMENT #4 temperature is reached. 2005 National Sales Meeting

9. TMX TMX Induction Motors- Continued • Durable/Low Maintenance Design • Only wear items are bearings and seals. • Used high-temperature shaft seal. • Used over-sized bearings for extended life. • Change at 10,000 to avoid potential problems. • Bearings filled with high-temp grease and sealed on both sides. • Clark will stock: Stator (includes temp senor), Rotor, Drive-end shield, Non-drive end shield, screws and other miscellaneous parts. These items can not be rebuilt. 2005 National Sales Meeting

10. TMX Traction Control Features • High travel speeds both loaded and unloaded. • Top speed for TMX 12-20 set at 9.3 mph loaded and unloaded. • Motor is not limiting factor. Control regulates speed. • Ramp start Feature- Control boosts voltage to motor producing higher starting torque. • Allows operator to start loaded truck on ramp without rollback. 2005 National Sales Meeting

11. TMX Traction Control Features • Anti-Roll Away Feature- If left unattended with the parking brake not set, but the key on, truck will slowly (about 1 mph) descend ramp regardless of directional lever position or truck orientation. • Motor encoder knows which direction truck is rolling. Control checks directional lever and accelerator input and applies counter-torque as needed. 2005 National Sales Meeting

12. TMX Traction Control Features • Three forms of regenerative braking are standard: • Service brake (foot brake) • Change of direction (Proportional to accelerator position) • Accelerator release (Proportional to accelerator position) • The Benefits are: • Brakes are hardly used, prolonging brake life. • Energy to stop truck goes back into battery, not into brakes. • Drive train is always under load. No rattle during coasting. 2005 National Sales Meeting

13. TMX Traction Control Features • Stall Protection • Control reduces current by 50% after several seconds of stall condition. • If maximum temperature is exceeded then control shuts down. • Accurate speed control via encoder feedback. • Can program lower travel speed. • Truck travels at same speed loaded and unloaded (not so without speed feedback). • Can set different limits for forward and reverse. • Consult factory if special speed reduction is required for your application (ESQ/SQ available). 2005 National Sales Meeting

14. TMX Traction Control Features • No delay during change of direction, as with DC systems. • No contactor switching delay like series system. • With brushed system the switching rate is limited to ensure good brush-to-commutator surface contact is maintained. • High acceleration rates = greater throughput. • Again, the TMX AC system is not limited by the need to maintain good commutation. 2005 National Sales Meeting

15. TMX Power Reversing Drive Control • Steer potentiometer relays steer tire position to control. • Control regulates speed and direction of both motors. • 0 to 8 degrees- Equal power to both motors • 8 to 71 degrees- Decrease speed of both wheels in proportion to steer angle. • 71 to 75 degrees- Inside wheel coasts • 75 to 90 degrees- Inside wheel powered in reverse • Pivot point is centered between drive tires. • Provides the tightest possible turning radius. • 2-wheel drive (versus only one) • Provides added traction, especially on wet or uneven surfaces. 2005 National Sales Meeting

17. TMX AC Pump Control is standard on every TMX……not a high priced option. 2005 National Sales Meeting

18. TMX Pump Control Features • One AC motor for lifting and steering operation. • Flow control valve ensures steering has priority. • Linear potentiometer on lift handle provides fully proportional lift. • Motor only runs as fast as needed, conserving energy. • Closing Tilt, Aux1 or Aux2 switches causes pump motor to spin at preset speed. • Motor speed can be adjusted to meet attachment needs. 2005 National Sales Meeting

19. TMX Pump Control Features • Low Noise Operation • Pump motor spins at 500 RPM to reduce steering noise. • Speed ramps up for all hydraulic functions. • Use “silent” pump to further reduce steering/lift noise. • On-demand steering option no longer needed. 2005 National Sales Meeting

20. TMX TMX Control Features • Thermal Protection • Standard on traction and pump controls. • Controls equipped with thermistors. • Thermal cut-back is gradual, not on/off. • Reduces current sent to motor. • Reduces control power output so it can start to cool. • Control will shutdown before exceeding maximum temperature. • Icon on dash lights to signify condition. 2005 National Sales Meeting

21. TMX TMX Control Features • Higher Efficiency-Longer Runtime • Overall the AC system is more efficient than equivalent DC system. • 13% longer run time per battery charge than equivalent DC system. • Higher Throughput • High lift and travel speeds, along with quick acceleration, mean faster throughput. • 12% more cycles per hour than equivalent DC system. 2005 National Sales Meeting

22. TMX TMX Control Features • Overall life cycle cost less than DC systems. • No FWD/RVS/1-A contactors to service. • No motor brushes to change. • Motor commutator does not need to be turned. 2005 National Sales Meeting

23. TMX TMX Control Features • Hand-Set service tool • Can change top speed (forward AND reverse), acceleration, plugging (all 3 forms), etc. • Use to check switches for proper operation. • Use to check wiring for proper connection. • Use to view status of any value that control measures. • Control has learning mode to set steer pot and accelerator end points. No need to fine tune by hand. 2005 National Sales Meeting

24. TMX TMX Control Features • Laptop service tool • Can do all that the handset can plus……… • Can update control software/firmware by flashing processes. • Can data log any value that control measures. • Can export alarm (fault) codes to file which can be emailed to Clark. 2005 National Sales Meeting

25. TMX Disadvantages of AC Technology • Control produces twice the amount of heat. • Clark uses a finned heat sink on all models. • Three fans used to help prevent control from overheating, even in demanding operations. 2005 National Sales Meeting

26. TMX Disadvantages of AC Technology • Some competitors claim to have a performance retention feature that maintains performance levels as the battery discharges. Such a feature could cause additional motor heating as voltage drops. • Same power required if same amount of work is performed. • Power equals volts times amps (P=V*I). • Therefore, lower voltage (at end of the shift) means higher current. • Higher current means considerably more heating. • Therefore- battery capacity is still important to maintain voltage. 2005 National Sales Meeting

27. TMX TMX Reliability • Proven Drive Axle • Same as TMG axle, except new pinion carrier because of new motor mounting flange. 2005 National Sales Meeting

28. TMX TMX Reliability • Proven Steer Axle • Same as on TMG. • Added grease zerk to trunnion housing. 2005 National Sales Meeting
