Track Tools
The track tools are used to assist in the installation of new tracks.
This section is intended to show how the tools are used only. A detailed instruction guide is provided when purchasing new tracks. Refer to that instruction guide when installing new tracks.
When the retainer clip is properly installed into the track pin groove is
should rotate freely inside of the groove.
The Track Pin Tools are used to assist in the installation of new tracks when the they are too tight making it diffi cult to align the pin holes.
Insert the track pin tools on the inside and outside adjacent pins to the
missing pin hole. You will need to hold these in place by hand.
On-Board Parts Box
The On-Board Parts Box contains spare track links, clips, and tools to quickly
replace or repair tracks. These components are located on-board the tug,
underneath the electronics cover
Start Up Guide
Remote Control Operation
Note:
The 3 Speed Toggle ranges from fast, to moderate, to slow. When operating the tug at slow speed it may be necessary to switch to the moderate or fast speed mode on the toggle when turning. Factors such as terrain and incline may aff ect the maneuverability of the tug. Adjust speed modes at your discretion.
- Switch the remote control ON. The power indicator light turns on and the remote control beeps once. If this does not happen, check the remote control battery connection for proper installation. When the battery level is low, the remote control will begin to beep repeatedly, signaling to replace or recharge the batteries.
- To drive the tug, move the control stick in the desired direction.
Warning: The control stick on the remote controller is very sensitive and will cause the tug to move if it is moved accidentally. Turn OFF the remote controller when not in use.
Note: If the remote controller is not used for a few minutes it will start beeping as a indicator that it is still in the ON position. This is not an indicator of a low battery.
Operating the Tug
-
Before turning on the tug, make sure the tracks and bottom of the tug are free from obstruction.
-
Turn the tug on using the ON/OFF switch. There will be a short series of beeps and then the ON/OFF switch will illuminate red to show the tug is on. The ON/OFF switch light will be on solid when the battery is fully charged. When the tug battery is low the ON/OFF switch light will blink and there will also be a beeping sound.
-
Turn on the power switch on the radio controller. The power indicator LED will illuminate green/blue in color. It is recommended you practice maneuvering the tug prior It is recommended you practice maneuvering the tug prior to loading the plane. o loading the plane.
-
It is recommended to use the radio in fast speed mode. Moderate and Slow speed mode should be used when maneuvering in tight quarters as it reduces the tugs power output.
-
When towing your airplane ALWAYS be cautious of the steering angle limitations of your aircraft. Do not over steer your aircraft with the tug. This can cause damage to your gear.
-
After lifting the tug off of the ground for any reason or taking it in and out of your aircraft, you must check the sprockets for proper seating along the tracks. If the sprocket is not properly seated it could result in damage to the track.
-
Visually check tracks for wear on the treads and wear on the inner plastic surfaces.
Also inspect for damaged or missing retainer clips as a result of driving over small rocks. Damaged treads should be replaced before operating the tug.
Adjusting the Wheel Cradle
-
Use the cradle release lever to unlatch the cradle and position the wheel cradle in the (down) loading position.
-
Place wheel chocks behind the rear tires of the plane to ensure the plane does not roll back.
-
Drive the tug under the wheel of the plane until the wheel cradle locks in the upright position. Apply pressure to the back gate to ensure the the latch is fully engaged. IF YOUR TIRE DOES NOT FIT REMOVE THE “CRADLE ADJUSTER” SEE STEP 5 FOR REMOVAL
-
Once the cradle is in the up position, move the tug so that the wheel is just touching the front roller.
-
Remove the cradle adjuster by holding one end in place and turning the other end, removing one of the the adjuster knobs. Pull the adjuster rod out from the adjuster roller.
-
Move the cradle adjuster to an adjustment hole near the tire, taking up the space inside the cradle. You do not want the tire to be too tight in the cradle. Leave space between the tire and the cradle adjuster for tire size variations.
-
Release the latch using the remote controller and move the tug out from under the plane. Drive the tug back under the tire to check that the wheel cradle is set up correctly and to ensure the cradle is latching securely. When releasing the wheel cradle, the tire should be against the back gate (or cradle adjuster). If not, the latch may not release properly.
Adjusting the Tire Guide Spacers
-
If the tire guide spacers are in the widest position and your tire does not fi t or it is too close of a fi t remove the tire guide spacers and adjustment pins.
-
Adjust the tire guide spacers by removing the adjustment pin and sliding the spacers towards each other. Ideally the tire guide spacers should be moved the same distance on each side to keep your tire centered in the cradle. The distance between the tire guide spacers should equal the width of your tire plus one inch maximum.
-
Align each tire guide spacer to the nearest hole in the adjustment pin block. Insert the adjustment pin in the nearest hole position to secure in place. Adjusting the spacers correctly will prevent the tire from turning inside the cradle.
Adjusting Track Tension
Track tension may need to be adjusted after several hours of use. Follow the instructions below for each track.
-
Remove 4 track cover screws and remove the outside plastic track cover.
-
Loosen 4 front end retainer screws with anallen wrench. Insert a flathead screw driver into the access slot and push the screw driver towards the tug to leverage the front end of the rail, tightening the track. While holding the screw driver in the desired position tighten the front end retainer screws. IF THE FRONT END OF THE RAIL IS FULLY EXTENDED AND THE TRACKS ARE LOOSE SEE STEPS 2B BELOW. If track tension is successful move on to step 3.
2B. Adjusting Track Tension on a Fully Extended Front End
The tug spare parts kit provided with the tug will be required.
2B-1. Verify the front end is fully extended by inspecting the indicator
line located next to the front end retainer screws. The indicator line will
line up with the edge of the tug main plate once the front end is full
extended.
2B-2. Remove 3 cover screws and remove the inside track cover.
2B-3. Loosen 4 front end retainer screws with an allen wrench and push
the front end of the the track to relieve track tension. Temporarily re-
tighten the front end retainer screws in the retracted state.
2B-4. Remove 2 adjacent Rotoclips from the front end of the tug. Remove 2 track pins with the Rotorclips on the opposite end intact and 2 track links.
Tip: Tap the end of the track pin using a hammer to drive the pin through
the Rotoclip.
The Rotoclip will not be reusable after removal.
2B-5. Remove one and align the ends of the track.
2B-6. Overlap the Track Links on each side of the track and insert the
track pin and rotoclip as shown below.
2B-7. Inspect the track pin and Rototclips. The Rotoclips should rotate freely inside the pin groove. Reinstall the Inside Plastic Track Cover. Section 2B is complete, proceed to step 2 for adjusting track tension.
There should be about a 1/2” of play at the center of the track.
Reinstall the plastic track covers.
Repeat steps for the other track.
Loading the Aircraft Wheel
-
Turn the tug power ON and the radio power ON.
-
Use the latch release switch on the remote controller to lower the wheel cradle.
-
Drive the tug positioning it just in front of the wheel. Some tail draggers can be approached from the front or the back depending on the wheel confi guration
-
Drive the tug under the wheel at a moderate speed, no need to get a running start.
-
The wheel will roll up onto the tug and will push the back gate of the cradle to the latched position.
Note: It may be necessary to apply a little pressure with your foot to the top of the electronics cover to get the wheel started onto the tug. -
Drive the tug in the forward or backward direction to maneuver the airplane to its desired location. Be cautious of the steering angle limitations of your aircraft. Do not over steer your aircraft with the tug. This can cause damage to your gear.
-
The circuit breaker reset buttons will trip if the tug is overloaded. This will cause the tug to be unresponsive to the remote controller. To reset the circuit breaker open the electronics cover and locate a two white or black button on the circuit board. See image below. Press it down to reset the circuit breaker.
Critical Note:
If the circuit breaker buttons pop up after being reset, the tug is being
overstressed and could cause damage to the circuit board. Address any
mechanical issues such as a seized sprocket or missing track retainer clips or
any driving conditions such as driving up a steep incline or towing above the
tugs capacity that could be causing the tug to overstress. If the issue
persists call or e-mail AC Air Technology tech support for further assistance.
Unloading the Aircraft Wheel
-
Turn the tug power ON and the remote control power ON if not already on.
-
Push the tug slightly forward so the airplane tire puts pressure on the back gate of the cradle.
The back gate is the gate that is closest to the latch mechanism. -
While holding a slight pressure on the back gate release the latch by holding the latch release button on the radio.
-
While still holding the latch release button move the tug away from the tire.
-
The front gate should go down and the airplane tire will roll out of the cradle.
Charging the Tug
-
Before charging your tug, the remote controller and tug should both be turned OFF.
Normal charger indicator lights:- Red …………………Charging
- Solid Green …………Fully Charged
- Flashing Green ………No Longer Charging
-
Leave the tug charging when it is not in use. The charger is equipped with “smart” charging technology, preventing the battery from overcharging. Keeping the tug on its charger this will prolong the life of the battery.
Charging the Remote Control
WARNING: Only use the supplied charger to charge the controller when using the supplied batteries or the following:
– 1200mAh to 2200 mAh Ni-MH or Ni-Cd ‘AA’ Rechargeable Batteries
Using the remote control charger with alkaline batteries installed can damage the controller. Do not use the charger if alkaline batteries are installed in the controller.
- Plug the transmitter charger into a 110v AC wall socket.
- Plug the connector from the charger into the charging jack on the transmitter. The charging indicator LED, located on the side of the transmitter, will illuminate green indicating the charger is charging. Once the transmitter is fully charged the charging indicator LED will turn off .
- The charging rate of the charger is 150mAh. When using the 1200mAh batteries that are supplied, the radio requires an 8 hour charge when fully discharged (1200/150=8). If using 2200mAh batteries, it will take approximately 15 hours to charge (2200/150=14.6).
It is recommended to leave the remote controller charging when not in use.
