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.

2-2 Operating the Tug
2. Start-Up Guide
Tug ON/OFF Switch
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.

13
Check sprockets 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 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.
