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 and to smooth over the transition. Ramps can be purchased from Airtug, if necessary, to
overcome high door sills or rough pavement.
For best results and traction, it is recommended to begin movement very slowly to set the trailer in
motion.
General Maintenance
Tire Pressure:
Max pressure is 115 PSI. Lowering the pressure will increase traction when
necessary
Battery:
Keep the battery fully charged. A battery maintainer is available by calling Airtug at
216-941-9781.
Hydrostatic Transaxle:
This should be checked for oil level. Add 20W-50 oil if level is low.
Drive Wheel Bearings:
Permanently lubricated.
Caster Zerk Fittings:
Needs to be lubed periodically to ensure ease of caster wheel steering.
Drive Chains:
Apply chain lube periodically depending on use and environment.
Tractive Ability:
If the tug seems to be losing tractive ability, it’s an indication of a loose drive belt.
The engine plate is mounted on slotted holes and can be moved rearward toward the operator, to
tighten the drive belt if necessary. Simply loosen the nuts, push the engine plate towards the rear of
the tug and tighten the bolts.
Engine:
Engine oil should be change at regular intervals depending on use. Refer to engine owners manual. Note:
drain hose attached to engine for ease of draining.
CAUTION:

* Do not allow anyone to stand directly in front of or behind the vehicle during testing.
* Make sure the Power switch is off.
* Use well-insulated tools.
* RUNAWAYS - Some conditions could cause the tug to run out of control. Jack up the tug and get
the drive wheels off the ground before attempting any work on the engine control circuitry.
* HIGH CURRENT ARCS - Batteries can supply very high power and arcs can occur if they are short
circuit. Wear safety glasses, and use properly insulated tools to prevent short circuit.
* Do not overload this tug beyond the rated capacity.
* This tug is designed for use only on hard level surfaces capable of sustaining the load.
* No alterations to the tug shall be made.
