The On-Board Parts Box contains spare track links, clips, and tools to quickly replace
or repair tracks. It also includes cradle shims and mounting screws to lift the wheel
cradle ramp away from the ground. When the ground is very uneven the wheel cradle
ramp may hit the ground preventing the aircraft from loading.These components are
located on-board the tug, underneath the electronics cover.

2-1. Radio Operation
2. Start Up Guide
1. Switch the radio on and make sure the power indicator light turns on and the
radio beeps once. If this does not happen, check to make sure the batteries
were installed correctly. When the battery level for the radio becomes low the
radio will begin to beep, signaling you to replace or recharge the batteries.
Note: The 3 Speed Toggle ranges from fast, moderate, and slow.
When operating the tug at slow speeds it may be neccessary to
switch to the moderate or fast speed position on the toggle when
turning at 90 degrees. Factors such as terrain and incline may
aff ect the maneuverability of the tug. Adjust the speed at your own
discretion.

2. Start Up Guide
Warning: The joystick on the remote control is very sensitive and will cause
the tug to move if it is moved accidentally. When not using the remote it is
recommended that the power switch is turned OFF.
Note: If the remote is not used for more than a couple 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.

3. Turn on the power switch on the radio controller. The power indicator LED will
illuminate green/blue in color.
It is recommended that you practice maneuvering the tug prior to loading the plane.

4. It is recommended to use the radio in fast speed mode. Moderate and Slow speed
mode should be used when manuvering in tight quarters as it reduces the tugs power
output.
2. 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.

Check for proper seating and alignment.
6. After lifting the tug off of the ground for any reason or taking it in and out of your
aircraft, you must check to make sure the sprockets are correctly seated on the
tracks. If the sprocket is not properly seated it could result in damage to the tracks.
7. Visually check the tracks for wear on the treads and wear on the inner plastic
surfaces. Also inspect for damaged or missing rotoclips as a result of driving over
small rocks. Damaged threads should be replaced beore operating the tug.
5. When towing your airplane ALWAYS be cautious of the steering angle limitations of
your aircraft. Do not oversteer your aircraft with the tug. This can cause damage to
your gear.

2-3. Adjusting Wheel Cradle to Your Tire
1. When towing a non-fairing aircraft make sure the front and back cradle gates are adjusted
in the fully extended position. For aircraft with fairings adjust the cradle gates to the lowest
setting. If extra clearance is needed position the Booster Plate on the center of the main
plate between the tire guide spacers.
2. To adjust the front gate remove the fl at head screws from each side and slide the right and
left ramp blocks to the desired position. Then reinstall the fl at head screws on each side.
Note: It may be easier to remove these screws with the link locking pins removed.

3. To adjust the back gate loosen the 4 fl at head screws on the back of the gate. Then
slide the right and left sliders to the desired position. Tighten all 4 of the fl at head
screws. Note: It may be easier to remove these screws with the link locking pins removed.

4. Use the cradle release lever to un-latch the cradle and position the wheel cradle in the
down position. Adjust the connecting links to the longest length by removing the link
locking pins and extending the links. Then re-insert the link locking pins in the link holes.

5. Place wheel chocks behind the rear tires of plane to ensure the plane does not roll
back.
6. Drive tug under the wheel of the plane until the wheel cradle locks in the upright position.
Make sure the wheel is touching the back gate as shown.

5. Remove the adjustment pins and push the front side of cradle until it is touching the
tire and re-install the pins. If the pins cannot be installed while the front side is
touching the tire, move the front side of cradle away from the tire until the pin can be
inserted into the next closest hole. You do not want this to be too tight on the tire.
Do not force the adjustment pins in.
6. Release the latch using the radio and back 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 latch always make sure
the wheel is against the back gate. If not, the latch may not release properly.

2-4. Adjusting the Tire Guide Spacers

Tire Guide Spacer
1. 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.
Widest Postion

2. Adjust the tire guide spacers by removing the adjustment pin and sliding the spacers
towards eachother. Ideally the tire guide spacers should move the same distance on
each side to keep the tire centered in the cradle. The distance between the tire guide
spacers should equal the width of your tire plus one inch maximum.
3. 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.
