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.
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.

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.

The On-Board Parts Box contains spare track links / shims, rotoclips, and a rotoclip
tool to quickly replace or repair tracks. It also includes cradle shim 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 com-
ponents are located on-board the tug, underneath the electronics cover.

1. 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 con-
nection for proper installation. When the battery level is low, the remote control will
begin to beep repeatedly, signaling to replace or recharge the batteries.
2. To drive the tug, move the control stick in the desired direction.
3. The Lazy Susan Lock & Cradle Release Switch is a 3 position switch. The Unlock
and Lock positions are used to lock the lazy susan rotation. The Release position is
to release the tire from the cradle while unloading.

2-2 Operating the Tug
2. Start-Up Guide
1. Before turning on the tug, make sure the tracks and bottom of the tug are free from
obstruction.
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.

3. Turn on the power switch on the radio controller. The power indicator LED will illumi-
nate green/blue in color.

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 maneuvering in tight quarters as it reduces the tugs
power output.
5. 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.

6. After lifting the tug off of the ground for any reason or taking it in and out of your air-
craft, you must check the sprockets for proper seating along the tracks. If the sprock-
et is not properly seated it could result in damage to the track.
7. 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.
Check sprockets for proper seating and alignment.

2-3 Loading The Aircraft Wheel
2. Start-Up Guide
Dual Wheel Aircraft Pre-Load Setup
Remove the tire guide spacers by removing the adjustment pins and sliding the tire
guide spacers out towards the center of the lazy susan.
Single Wheel Aircraft Pre-Load Setup
Use the tire guide spacers provided (see Section 2-6 for adjustment)

Aircraft with Chine Tires Pre-Load Setup
Replace the tire guide spacers with the tire guide spacers for chine tires by removing
2 fl at head screws with a 5/32” drive. Add removable thread-locker on the screw threads.
When tightening the screws onto the tire guide spacers for chine tires, verify that the
mounting blocks are parallel. If not, they may not slide once installed onto the lazy susan.

WARNING:
DO NOT PUT ANY PART OF YOUR BODY IN THE MECHANISM WHILE
RELEASING THE LATCH. SEVERE BODILY INJURY CAN OCCUR.
1. Once the pre-load setup is complete turn on the tug power switch and the radio con-
troller power switch, see section 2-1 and 2-2 for details. The wheel ramp needs to be
in the down position before loading the aircraft wheel. If the wheel ramp is in the up
position then hold the latch release switch on the radio controller and slowly rotate
the lazy susan with the controller until the latch releases the ramp and it falls to the
down position. The ramp release only occurs when the lazy susan is oriented with
the wheel ramp facing forward. Once the wheel ramp is in the down position toggle
the latch release switch to the middle position, locking the lazy susan from rotating.

WARNING:
DO NOT SIT IN THE PLANE WHILE DRIVING THE TUG.
TO PREVENT GOING BEYOND YOUR STEERING LIMITS IT IS HIGHLY
RECOMMENDED THAT YOU LOCK THE LAZY SUSAN FROM
ROTATING WHILE GOING UP AND DOWN HILLS AND MOVING
ALONG A STRAIGHT PATH. THE LAZY SUSAN FEATURE SHOULD ONLY BE
USED ON FLAT GROUND AND WHEN MANEUVERING IN TIGHT QUARTERS.

2. Drive the tug to line up the aircraft tire with the center of the wheel ramp.
3. Drive the tug under the aircraft tire until the tire is positioned on top of the lazy
susan. It may be necessary to chock the wheels to keep the plane from moving.

4. Continue driving the tug under the tire until the rear gate locks onto the latch and the
wheel ramp is in the up position.
5. The Lazy Susan Lock switch on the radio can be moved to the unlocked position
during operation to allow 180° of rotation, refer to section 2-1.
6. The circuit breaker reset buttons will trip if the tug is overloaded. To reset the circuit
breakers open the access cover and locate the two white or black buttons on the
circuit board. See image above. Press them down to reset the circuit breakers.

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 sup-
port for further assistance.

2-4 Unloading The Aircraft Wheel
2. Start-Up Guide
1. Toggle the Lazy Susan Lock Switch in the middle position and rotate the tug under
the aircraft tire until the wheel ramp is facing the front of the tug. Push the tug so the
rear gate is slightly pushing against the tire.
Note: It is recommended to chock the wheels to keep the plane from moving

2. Hold the latch release switch on the radio controller and slightly rotate the tug under
the tire until the latch releases the rear gate. You will need to visually verify that the
latch is released. This may require rotating the tug back and forth slightly until the
latch releases.
3. When the latch releases, continue holding the latch release switch on the radio con-
troller and then drive the tug away from the tire. The wheel ramp should pivot to the
down position as you move the tug
