2.0 SAFETY INFORMATION
2.1 USAGE AND SAFETY INFORMATION
To insure safe operations please read the following statements and understand their meaning. Also refer to your equipment
manufacturer’s manual for other important safety information. This manual contains safety precautions which are explained
below. Please read carefully.
WARNING! —Warning is used to indicate the presence of a hazard that can cause severe personal injury,
death, or substantial property damage if the warning notice is ignored.
CAUTION! —Caution is used to indicate the presence of a hazard that will or can cause minor personal injury
or property damage if the caution notice is ignored.
2.2 OPERATING SAFETY GUIDELINES
1. Under normal circumstances do not use the Parking Brake Hand Button to stop the JETporter while moving. The
Parking Brake hand Button is provided to set the parking brake faster when stopped on an Incline. When stopping the
JETporter on an incline, hold the vehicle to a stop using the Joystick. Press and hold the Parking Brake Hand Button
before releasing the Joystick. This will eliminate the time lapse between releasing the Joystick and the automatic setting
of the parking.
2. JETporter motion is normally stopped by moving the Joystick to the Neutral (upright) position. Moving the Joystick through
Neutral and into the opposite direction will supply the same braking effort as moving it to the Neutral position.
WARNING
Available stopping torque is reduced when the transmission is set for high gear. Stopping distances may
be longer when the transmission is set for high gear.
3. Always use the safety strap and tighten snugly. This will prevent the aircraft from rolling forward if a sudden stop occurs.
4. Accelerate slowly. Always operate the JETporter as smoothly as possible to prevent damage to the nose wheel strut of
the towed aircraft.
5. Do not leave JETporter unattended when children are present.
6. Do not allow anyone to “sit”, or “ride”, on the deck of the JETporter while in motion.
2.2 Operating safety guidelines continued on following page.

Models: JP30, JP30L
Electric Towbarless Tug
07/2015 | Rev. 10 Page | 2
2.2 OPERATING SAFETY GUIDELINES (continued)
7. The JETporter is equipped with a safety brake which prevents the vehicle from moving when the systems are off.
However, the JETporter can be moved or towed by putting the transaxle into neutral. Standing on the cradle looking aft,
the shift knob is located on the right side of the transaxle. Look for a round stop collar fastened to a shaft sticking out the
side. When the knob is pushed all the way in, it is in low gear. Pull it out half way and the transaxle is in neutral. Pull it all
the way out for high gear. WARNING
When the transmission is set to the Neutral position, the JETporter is free to roll and the brakes will be
ineffective. Use this position only for the purpose of slowly moving on a non-functioning JETporter. Wheel
chocks may be needed for stopping. Otherwise, be sure the transmission is firmly set to the full in position
(low speed) or the full out position (high speed).
8. Routinely inspect the spring on the hand winch for proper tension. Over time this spring may relax and not keep the dog
firmly in the sprocket which could allow the winch to unspool and let the aircraft roll off the front of the cradle and cause
damage to the aircraft or injury to people or objects nearby. Maintain a firm grip on the winch handle at all times and never
release the handle when the ratchet lever is in unlocked position with a load on the winch. Otherwise, the handle will spin
violently which could cause personal injury.
9. Use extreme caution while operating under adverse weather conditions. With snow or ice on the ramp traction can be
reduced significantly which could result in loss of control of tug and towed aircraft. Evaluate weather conditions to
determine if the aircraft can be moved safely. If in doubt do not attempt to move aircraft.
2.3 BATTERY SAFETY GUIDELINES
1. Always wear eye protection and rubber gloves when working with batteries.
2. Never wear jewelry, watches or rings while working around batteries.
3. When working on JETporter, always remove all power leads from batteries. The battery pack is capable of extremely high
currents and could cause serious damage or injury if short-circuited.
4. If battery acid is accidentally spilled on the skin, immediately flush the area with large amounts of water. Electrolyte
splashed in the eyes is extremely dangerous! If this should happen, force the eye open and flood it with cool, clean
water for approximately fifteen minutes. A doctor should be called immediately when the accident occurs.
5. If you have any doubts or questions, contact Tronair.
2.4 GROUND POWER UNIT SAFETY GUIDELINES
1. Read 6.4 “Safety Precautions” in the battery care section of this manual.
2. Never guess when it comes to high current electrical equipment. Think about what you are doing before you do it.
3. Read and understand the cautionary statements in above section.
4. Always plug the black plug into the black socket. Reverse voltage can damage aircraft electrical systems.
5. Never over boost the electrical system by using a higher voltage than the rated voltage for the aircraft.
6. Pressing the Emergency Stop Button will disconnect the negative side of the GPU circuit. The Emergency Stop Button
must be in the pulled up position for the GPU to function.
2.5 SAFETY GUIDELINES
1. DO NOT USE THE PARKING BRAKE HAND BUTTON TO STOP THE JETPORTER WHILE MOVING. The Parking
Brake Hand Button allows faster setting of the parking brake for stopping and holding on inclines.
2. JETporter motion is normally stopped by returning the Joystick to the Neutral upright position. Moving the Joystick through
Neutral and into the opposite direction will result in the same braking effort as moving it to Neutral.
WARNING
Available stopping torque is reduced when the transmission is set for high gear. Stopping distances may
be longer when the transmission is set for high gear.
3. Accelerate slowly. Always operate the JETporter as smoothly as possible to prevent damage to the nose wheel strut of
the towed aircraft.
4. Do not leave JETporter unattended when children are present.
WARNING
Do not allow anyone to sit or ride on the diamond plate or front fenders of the JETporter while in motion.
5. The JETporter is equipped with a safety brake, which prevents the vehicle from moving when the systems are off.
However the JETporter can be moved or towed by putting the transmission in neutral.
WARNING
When the transmission is set to the Neutral position, the JETporter is free to roll and the brakes will be
ineffective. Use this position only for the purpose of slowly moving on a non-functioning JETporter. Wheel
chocks may be needed for stopping. Otherwise, be sure the transmission is firmly set to the full in position
(low speed) or the full out position (high speed).

2.5 SAFETY GUIDELINES (continued)
6. Operators are expected to know and observe all normal safety procedures for working around aircraft. The operator’s
knowledge of these general aviation safety procedures is a basic assumption for this manual. The omission of general
aircraft safety procedures from the JETporter Operator’s Manual is no excuse for the operator’s failure to apply them.
7. In the event the Ground Power Unit (GPU) is used, the operator is expected to have a working knowledge of electrical
characteristics of the specific aircraft being assisted. Damage to the aircraft’s electrical system can occur from over
voltage, lack of proper isolation or incorrect polarity. Such mishaps are entirely preventable if the operator knows the
aircraft characteristics and proceeds with care.
8. For moving aircraft up or down inclines/slopes, a qualified operator should be in the aircraft cockpit to utilize the aircraft’s
brakes for safety/backup.
9. JETporter, like any piece of machinery, should be operated by responsible personnel who are alert, attentive and aware of
the potential for serious injury or death. Operators should not be under the influence of intoxicants, drugs or any
substance that would alter or impair their actions or ability to make responsible and prudent judgments. No person should
be allowed to operate the JETporter without reading and understanding this operator manual.
10. Proper attire should be worn while operating JETporter. Loose fitting clothing should be avoided. Appropriate outdoor
work shoes should be worn at all times.
11. Eye protection and rubber gloves should be worn when adding water or working with the batteries. Remember that the
current capability of the batteries is extremely high.
12. Important! All switches need to be turned off before plugging in the JETporter for charging.
13. The diamond plate over the batteries should always be removed when charging the batteries. During the charging cycle,
explosive hydrogen gas is expelled. Open flame or sparks must be avoided. Do not smoke near the batteries while
charging
14. Read Section 6 and review and understand safety procedures for working around batteries.
15. When moving in reverse direction, look both ways and clear the area of other traffic and obstacles.
16. Contact Tronair before making substitutions of any parts.

(Appendix V).
JP30L A built-in automatic 40 AMP 48 Volt DC charger is shipped wired for 115 (120) Volts AC, 20 AMP, 60 HZ. It must
operate from a 125 Volt AC, 30 amp circuit. It can be configured for 230 Volts AC Single Phase 50/60 HZ by changing the fuse
positions. Instructions for changing the fuse positions can be found in the Quick Charge Manual (Appendix V).
5.8 BRAKING
Regenerative braking is provided by the solid state motor controller. Braking occurs as the Joystick is moved toward the
Neutral upright position. Braking strength ramps up based on the programmed deceleration curve.
5.9 PARKING BRAKE
An electrically released disk brake is mounted on the drive motor. The parking brake sets automatically when the Person
Present (deadman) switch on the Joystick is released and regen braking has brought the JETporter to a stop. A Parking Brake
Hand Button is to the left of the steering wheel. This button is to be used to eliminate the time laps between the release of the
Joystick and the automatic setting of the parking brake when stopping on inclines.
5.10 WINCH
A heavy duty, two-speed hand winch is standard. A nylon strap is included so that aircraft will not be damaged or scratched.
5.11 LIFT CRADLE
A direct current motor and hydraulic pump operate two lift cylinders that raise and lower the nose wheel lift cradle. Control is
by “Raise” and “Lower” push buttons located on the control panel. The lift cradle is designed to accommodate both dual and
single nose wheels.
5.12 STEERING AXLE
Dual 4.80 x 8” (16 inch O.D.) industrial tires are used for steering. The steering axle assembly rides on tapered roller bearings,
as do the wheels. The steering axle moves in a 120º arc to provide a very tight turning radius.
5.13 STEERING
A 16” industrial steering wheel provides comfortable steering without power assist. An industrial oil bath gear reducer provides
primary gear reduction. Secondary reduction is provided by roller chain. The steering wheel is tilted rearward 10º from
horizontal to provide the most comfortable and efficient driving position.
5.14 LIGHTING
Forward and rear LED headlights are included. Headlights are turned on with toggle switch. Strobe comes on when tug is
started.
5.15 DRIVE TIRES
Drive tires are dual 16 x 6-8 solid rubber traction tires.
5.16 OPERATORS PLATFORM
The operator’s platform is designed to accommodate the operator and one passenger. The platform is free from pedals and
brake levers that encumber the operator.

Models: JP30, JP30L
Electric Towbarless Tug
07/2015 | Rev. 10 Page | 6
6.0 OPERATING INSTRUCTIONS
1. Stand on Operator Platform and pull the E-stop up.
2. Turn the “Off-On-Start” switch to the “Start” position and then release.
3. When operating the JETporter, stand firmly on the operator’s platform, with legs spread slightly apart and body braced
against the backrest. Keep one hand firmly on the steering wheel and the other on the Joystick. Do not move JETporter
any faster than is necessary.
4. Make sure the cradle is raised off the ground. Grab the Joystick and squeeze the Person Present (deadman) switch.
Slowly move the Joystick in the desired direction of travel. If you activate the throttle before squeezing deadman switch,
your JETporter will not move. This is a safety feature built into the controller. Release the throttle back to neutral and start
over in the direction you want to travel.
5. This vehicle is NOT designed to coast. Accelerating, braking, and maintaining a constant speed are all very dependent
on Joystick position. This results in a vehicle that is very easy to drive and extremely easy to control on inclines. Squeeze
and hold the deadman switch on the Joystick. Slowly move the Joystick in the Forward or Reverse direction to accelerate;
slowly move the Joystick back to center to brake. Hold the Joystick steady for a steady speed.
6. Moving the Joystick back to center, moving the Joystick into the opposite direction, or releasing the deadman lever will all
brake at the same rate.
7. The Parking Brake Hand Button can be used for more precise stopping on inclines. Hold the JETporter to a stop using the
Joystick; press and hold the Parking Brake Hand Button before releasing the Joystick. This will eliminate the time laps
between releasing the deadman and the automatic setting of the parking brake.
WARNING
Available stopping torque is reduced when the transmission is set for high gear. Stopping distances may
be longer when the transmission is set for high gear.
WARNING
Do not make sharp turns while moving rapidly. Always look behind you before backing up.
6.1 LOADING AIRCRAFT
1. Check with the owner/operator of the aircraft to determine what
precautions need to be taken to properly tow the aircraft. Determine if any
steering linkages or other components need to be disconnected or bypassed
in order to allow the nose wheel to turn within its prescribed turning limits.
2. The lift cradle is equipped with three sets of holes in the side support arms to
accept a 1” diameter 20” long bar. The top two sets of holes are to be used for
aircraft without nose wheel pants. Based on the diameter of the nose wheel
put the bar through the set of holes that will best handle that particular aircraft.
The top hole for example would be used for large diameter (18”) single nose
wheel Cessna Citations or Lear Jets. Put the bar through the lowest set of
holes only for single engine aircraft that have nose wheel pants. The nose
wheel pant will slide over the top of the bar.
Note: With whatever set of holes you use, lift the cradle only high enough off the ground to clear obstacles while
moving the aircraft. If you raise the cradle too high a sudden stop or other circumstance could cause the nose wheel
of the aircraft to roll over the top of the bar and onto the tug causing damage to the aircraft and possible injury to the
operator.
To avoid this situation use the safety strap as described in #3. Notice that the moveable side plates are tapered as they
go forward. This is to keep the side plates from touching the bottom of the side of the wheel pant when the cradle is
raised. Pay attention as you raise the cradle and make sure you do not raise it too high and allow the side plates to
contact the bottom of the wheel pant.
3. Position the JETporter in front of the aircraft nose wheel and lower the lift cradle to the ground. Winch the nose wheel onto
the lift cradle, utilizing the strut strap or appropriate attachment. Make sure there is a little slack in the winch strap
before lifting the cradle as it will move up and away from the tug as it is raised. This will increase the tension in
the strap and could damage the aircraft nose wheel assembly as the cradle is being raised. Once the cradle is
raised to the desired height then retighten the winch strap so it has adequate tension in it to keep the aircraft
secure in the cradle. Some aircraft have sensors or other components attached to the nose wheel strut and may be
damaged by using the nylon strut strap. In such cases do not move the aircraft unless you have an appropriate towing
adapter. Check for proper ratchet operation on each use of the winch. Do not use if ratchet will not lock properly, seek
immediate repairs.

07/2015 | Rev. 10 Page | 7
6.1 LOADING AIRCRAFT (continued)
4. Secure the aircraft nose wheel with the safety strap. The safety strap is a strap with
a ratchet mechanism and spring clip hooks at each end. On either side of the
forward end of the cradle are brackets that have a hole in each of them. These
holes on either side are used for the safety strap. After the aircraft has been
winched onto the cradle hook one end of the safety strap to one side of the cradle
and position the strap up and over the top of the nose wheel (or nose wheel pant)
and in front of the oleo strut. Hook the other end into the hole on the other side of
the cradle and use the ratchet to snug up the strap. Be very careful not to position
the strap where it might damage some component of the nose wheel assembly. Do
not over tighten as it only needs to be snug enough to prevent the nose wheel from
possibly lifting upward out of the cradle. On some aircraft with nose wheel pants it
may make sense to run the safety strap through a scissors on the aft side of the
strut.
5. If the aircraft has a single nosewheel versus a dual nosewheel then
the moveable side plates will be needed in order to keep the nose
wheel from twisting or rotating while the aircraft is being moved.
Once the nose wheel is in position on the cradle, lift up on the ring of
the index plunger on top of the square tube on the cradle and slide
the moveable side plate in the proper direction. If you release the
ring on the plunger when you start to reposition the side plate it will
drop into the next available hole of the inner square tube.
6. Raise the lift cradle high enough to clear obstacles on the ground.
7. If moving aircraft over 15,000 lbs make sure the transaxle is in LOW
gear. The knob for this is located on the right side of the transaxle
as you are standing on the cradle looking aft towards the steering wheel. There is a sticker on the front center of the
transaxle that shows to push the shaft all the way in (to your left) to place it in low gear.
8. Move the aircraft by slowly advancing the accelerator lever in the direction of travel.
9. For moving aircraft up or down inclines/slopes, a qualified operator should be in the aircraft cockpit to utilize the aircraft’s
brakes for safety/backup.
6.2 UNLOADING AIRCRAFT
1. To unload aircraft, lower lift cradle to a position 1/2” above the ground. Remove strut strap and safety strap.
2. Chock the aircrafts main wheels and then back JETporter away from the aircraft, allowing the nose wheel of the aircraft to
roll off lift cradle onto the ground.
7.0 GROUND POWER UNIT
7.1 DESCRIPTION
1. The ground power unit (GPU) is an integral part of JETporter.The traction batteries serve as the source of power to start
the aircraft.
2. The black terminal is the negative, terminal. Always connect the black plug into the black terminal. This provides the
ground connection to the aircraft.
3. The first red terminal is the 12 volt terminal. With the batteries in a fully charged condition, the terminal voltage will be
closer to 14 volts. With the batteries in a partially charged condition, the voltage will be typically closer to 12 volts. To
assist a 12 volt aircraft, plug the black lead into the black terminal and the red plug into the 12 volt terminal.
4. The second red terminal, labeled 24 volt, is used to start aircraft with 24 volt systems. Plug the black plug into the black
terminal and the red plug into the 24/ volt terminal. When the batteries are in a fully charged condition, the voltage will be
near 26 volts. As the batteries are used, the voltage will decrease to nearly 24 volts.
5. The third red terminal, labeled 30 volt, may be used to start 28 volt aircraft, especially in cold weather, or when conditions
require additional voltage. Check with the aircraft owner/operator to make sure the increased voltage is within the
aircraft’s electrical system tolerances. When the batteries are in a fully charged condition, the voltage will be near 31 volts.
This increased voltage will make starting easier. CAUTION
Do not use the 30 volt terminal unless the aircraft electrical system is isolated from the starting circuit. The
over voltage could damage the aircraft’s electrical system.
6. The GPU positive voltage is connected directly to the traction batteries and does not have a fuse in the circuit. Pressing
the E-stop will disconnect the negative side of the GPU circuit. Be extremely careful when handling the GPU cables.
Extremely high currents are possible.

7.0 GROUND POWER UNIT (continued)
7.2 CONNECTION TO AIRCRAFT
1. Adapters are included with JETporter. Position JETporter so the power socket on the aircraft is in a location that will allow
the engine to be started safely. Be sure the “Master” switch in the aircraft is off prior to starting the engines. Boost voltage
could damage the aircraft’s electrical system.
WARNING
Consult the owner/operator of the aircraft to confirm proper procedures for a GPU start.
2. Determine the voltage of the aircraft that is to be boosted. Attach the appropriate adapter to the end of the long boost
cables. Connect the black plug (negative) into the black socket in the front of the GPU panel. Always connect the GPU
cables to the tug first before making connection to the aircraft.
3. Connect the red plug into the appropriate red socket in the front of the GPU panel. Be sure that the voltage selected is
correct for the Aircraft that is being boosted. Again, make sure the connection is made to the tug prior to connecting
to the aircraft.
CAUTION
Do not allow aircraft to draw full power for more than one minute in ten minutes. Excessive use of the GPU
could cause severe heating and damage the batteries and/or GPU cables.
WARNING
Do not use the GPU system to run aircraft heating and cooling systems. The GPU system is not designed
to handle these continuous loads and can cause damage to the batteries and GPU cables. Under these
circumstances the batteries could produce explosive gases which, if ignited, may cause serious injury to
nearby personnel.
4. Once the aircraft engine has started, disconnect the GPU cable at the aircraft then from JETporter. Carefully wind the
GPU cables and stow them in one of the storage compartments on JETporter.
7.3 DETERMINING PROPER VOLTAGE
1. Check the aircraft ratings to determine the proper voltage, if unknown. DO NOT GUESS. Over-voltage can damage
aircraft electrical systems.
2. Do not unplug the GPU cables while the aircraft is being started. High currents can cause severe arcing.
8.0 BATTERY CARE
This section provides general instructions for good battery care. Please refer to Appendix in this section for additional
information on battery care.
8.1 WATER
1. Add approved water only to a fully charged battery. You can use local tap water as long as it is not high in mineral
deposits or other hard deposits.
2. Keep electrolyte water level above separator protectors.
3. Keep battery cells filled to proper level. Low water can cause permanent damage to batteries.
4. Check water level once a week. Replace water lost to evaporation. Never add water to a discharged battery.
5. Never add sulfuric acid to a battery.
6. Do not transfer acid from one cell to another.
7. Never allow the batteries to stand in an uncharged state. Plate damage will occur.
8.2 CHARGING
1. Keep battery compartment open during charging to ensure proper ventilation.
2. The batteries should be recharged when the state of charge indicator has declined to 30-40%.
For the Honeywell state of charge indicators, charge when the yellow LED lights are down to 3. This will be in the 30-40%
range. The last yellow LED will begin to flash when the charge drops below 25%.
For the Curtis state of charge indicators, charge when the LEDs in the yellow range are showing. This will be in the 30-
40% range. There are 3 LEDs in the yellow range. At 30% charge, there will be a flashing red LED. At 20% charge, there
will be a double flashing red LED.
Do not skim charge or constantly top up the batteries, as this will shorten the life considerably.
If the vehicle is not being used, batteries should be stored at full charge and topped up monthly.
3. Keep flame and metal away from the battery tops to prevent battery gasses from exploding.
4. Cool before charging or operating, if battery is above 115º F.
5. The Emergency Stop Switch MUST be in the “off” position during charging.

8.0 BATTERY CARE (continued)
8.3 PRECAUTIONS
1. Keep battery tops clean and dry.
2. Keep vent caps tightly in place.
3. Do not use battery with specific gravity below 1.155.
4. Be sure battery compartment cover is removed and they are well vented while charging batteries.
5. Do not overcharge batteries. Allow several hours use between charges.
8.4 BATTERY MAINTENANCE
See Appendix I for additional information on battery maintenance.
9.0 TROUBLESHOOTING
9.1 GENERAL TROUBLESHOOTING
9.1.1 If The Tug Will Not Run
Is the E-stop button depressed? Pull up to release.
Check the wire connections on the joystick and make sure no wires have come loose.
Check switch positions. Are E-stop and start switches on?
Are you squeezing the deadman switch on the Joystick. The deadman switch must be squeezed before moving the
Joystick and held continually for the vehicle to move.
Check that all battery connections are tight and show no signs of corrosion.
Check that all batteries are fully charged and that none has defective cells.
Check wiring for loose connections.
Check for faulty forward-reverse switches. They are on the bottom of the joystick.
Check for worn motor brushes.
Check direction switches on the Joystick and see if they are engaging and sending voltage to controller.
Make sure wire harness plugs are seated correctly in controller.
9.1.2 If Tug Runs But Lacks Sufficient Power
Check batteries –specific gravity
Check to see that brakes are not dragging.
Check all battery and switch connections to see that they are clean and tight.
Check for loose wiring.
9.2 BATTERY CHARGER TROUBLE SHOOTING
The battery charger is configured to best match the CROWN batteries that are shipped with the JETporter. In this
configuration, the charger charges the batteries until the charging voltage reaches 56 Volts DC. At that time, a counter starts to
begin a 3 hour gassing cycle before the charge is shown as complete. This means that any time the charger is plugged in,
even if the batteries are fully charged, the charger will run for a minimum of three hours. If necessary, for location operational
purposes, the length of the charging cycle (gassing period) can shortened. Contact Tronair or contact Quick Charge direct
from the information located in the Quick Charge Manual (Appendix V).
Pressing the Equalize button during the charge cycle will run a second 3 hour gassing cycle when the first charge is complete.
There is a panel meter in the charger for purposes of trouble shooting. The meter has a toggle to switch from voltage to
amperage. When the charger is on, the voltage will be the charging voltage and the amperage will be the charging amperage.
When the charger is off (not plugged into an AC source) the voltage will be battery voltage and the amperage will read at or
near 0.
Remove the rear panel from the driver’s console to access the charger panel meter.
9.3 CRADLE UP OR DOWN DOESN’T WORK
If the cradle goes one direction but not the other, or goes really slow in the other direction it could be a faulty coil on one of the
cartridge valves or missing wiring if wiring has been disconnected for some reason. If one coil doesn’t work then fluid can flow
one direction because the powered side cartridge valve will work and the return fluid will push open the other valve. But the
reverse will not work as the non-working cartridge valve can’t open therefore preventing fluid from getting to the cylinders.

10.0 MAINTENANCE WARNING
All work on the JETporter tug should be performed by competent repair personnel. Before performing
maintenance, review all safety procedures.
10.1 GENERAL MAINTENANCE
1. After the JETporter has been in operation for (4) months the steering chain should be tightened to take up the slack from
initial chain stretch. If this is not done there is a chance that the steering chain could jump off the sprocket, which would
cause the steering system to fail. Access the chain through the knee level panel at the driver’s platform. Under the
steering sub-frame there are three bolt heads facing down that screw into the steering ratio multiplier. Loosen these three
bolts and pull the whole assembly back to tighten the chain. Retighten the three bolts while still applying tension to the
steering assembly.
2. Check the electrical connections for loosening; tighten if necessary.
3. Check battery water level weekly
4. Paint the terminals of the batteries with acid-proof coating.
5. Check all bolts and hydraulic fittings for looseness. Tighten if necessary.
6. If battery acid should spill into the battery box or on metal parts, flush with water and baking soda. Sprinkle baking soda in
bottom of battery box to prevent corrosion. WARNING
Battery acid is corrosive. Wear gloves and eye protection when servicing batteries.
7. Keep JETporter in a clean condition. Check for any unusual conditions, such as bent metal or broken parts.
8. Electric vehicles, such as JETporter, should never be steam cleaned.
9. Tire Replacement. Replace worn tires with equal or greater capacity tires only. Do not change tire dimensions when
replacing tires.

07/2015 | Rev. 10 Page | 11
10.2 LUBRICATION (continued)
4. Repack the steering shaft roller bearings with wheel bearing grease on an annual basis.
5. Repack all three steering axle wheel bearings with wheel bearing grease on an annual basis. Clean bearings and remove
all old grease using solvent. Do not mix greases having different bases.
6. Check the oil in the steering gearbox annually. Add SAE 90W, if necessary.
7. Check the oil level in the hydraulic reservoir every day during preoperational check. Add hydraulic oil, if necessary. Use
an AW 46 hydraulic oil. Make sure the cradle cylinders are fully retracted prior to adding fluid. Fluid level should be at
least one and half inches down from the top.
8. Check the transaxle fluid level every month. Remove the level screw which faces forward and is near the center line of the
axle. If oil is not to this level, add SAE 90W at the filler plug on top of the transaxle. The transaxle holds seven (7) pints.
9. The motor bearings and the drive wheel bearings are sealed and require no lubrication.
10. The steering shaft bearing and the accelerator control do not require lubrication.
10.3 NYLON STRAPS
1. Preshift Inspection Of Straps: Winch, strut and safety straps should be inspected during the daily preshift inspection
process. WARNING
These straps are the primary means of securing the aircraft to the JETporter. Failure of these components
could result in death or serious injury and/or significant damage to the aircraft.
2. Worn/Damaged Straps: Discontinue use of any strap that shows signs of wear or damage such as torn or frayed edges,
damaged “D” rings or hooks, loose or broken stitching, signs of chemical damage or holes in webbing of strap. See
attached sheet for examples of unserviceable straps.
3. Periodic Strap Inspection: Strut and winch straps are degraded in tension capacity by normal wear, age and exposure
to the elements. Operators should inspect straps daily during normal preshift inspection.
4. Routine Strap Replacement: Strut and winch straps should be associated with a specific tug and tracked for age. Straps
should be routinely replaced annually or after 150 hours of use, whichever occurs first. Replacement is mandatory if
inspection shows any wear or damage that would lower maximum capacity of the straps or fittings.
5. Non-Routine Strap Replacement: Enclosure (1) is provided as a guideline for inspecting straps. Straps provide the
primary securing device for your aircraft and as such should be of primary importance in the maintenance cycle.
10.4 COMPONENT WEAR
1. The parking brake on the rear of the motor disk will wear very slowly. If the dynamic motor braking is utilized, the parking
brake will last for many years.
2. Tires should be replaced when the tread depth is less than ¼ in.
3. Motor Brushes: Motor brushes will wear very slowly; however, they should be checked at least once a year.
10.5 REPAIRS
2. Repairs needed on your JETporter should be performed by competent repair personnel.
3. The batteries in your JETporter must be replaced with like batteries. The charger has been designed to operate with this
size battery. Do not substitute a higher or lower Amp/hour rated battery. All batteries should be replaced at the same time.
4. Do not attempt to repair the electronic controller. Contact Tronair for proper repair procedures.
5. Contact Tronair before making substitutions of any parts.
