Assembly & Operating Instructions
MODELS: TT-SD-GM
Braking too abruptly or moving too fast can
seriously damage the differential ring gear. This is
considered abuse and is not covered by the
transaxle warranty.
Airtug, LLC is not responsible for damage sustained
when proper clearance is not maintained by the
operator between the tug and its surroundings.
WARNING:
This tug is shipped WITHOUT gas or oil in the engine. Using the 10W-30 Oil provided,
fill to the “Full” mark on the dipstick. Fill the fuel tank with regular unleaded gasoline (Non ethanol).
Refer to engine manual for additional information.
Engine Operation:
Press the throttle all the way forward to “Choke” the engine, then press the
starter button
by foot located on the tug frame behind the engine. The engine is stopped by pulling
the throttle all the way back. Use a low amp battery charger (available at Airtug 216-941-9781) to
maintain a fully charged battery between use, especially in colder environments.
Tug Operations:
The twist grip handle operates the hydrostatic transaxle. Rotating the twist
grips forward or aft moves the Airtug accordingly. Rotating the grip slightly in either direction will
move the tug very slowly. As you increase the rotation of the handle grips, the tug speed increases.
Maximum torque is applied at very slow speeds ensuring excellent maneuverability while rotating the
hand grips fully results in maximum speed. The hydrostatic transaxle provides smooth variable
speed control throughout the entire range of grip motion. The twist grip is spring loaded to “return -to-
brake position.” Nevertheless, it is not recommended to walk away from the tug while the engine is
running. While moving the trailer, braking is effected by gradually returning the grip to the neutral or
brake position. Even while moving the trailer on a downgrade, the tug will only go as fast as you have
the twist grip turned. Braking too abruptly with a heavy trailer or moving too fast can seriously
damage the differential ring gear. This is considered abuse and is not covered by the transaxle
warranty. When moving over the door weather edge or door rail, it’s recommended to have a little
momentum. Ramps can be purchased from Airtug, if necessary, to overcome high door sills or rough
pavement.
For best results and traction when moving a trailer, it is recommended to begin movement very slowly
to set the trailer in motion.
