Aircraft Loading:
Position the Airtug up to the the nose wheel with the ramp centered on the
wheel and stop. Using the strut strap or optional “J” hook (purchased separately), connect the winch
hook and using the winch pull the aircraft onto the tug until the tire hits the backstop or chock
accessory for aircraft with a nose wheel fairing. Make sure the winch is in the locked position prior to
moving the tug. All Airtug load platforms are designed for retractable gear. All Airtug’s require
adapters to accommodate tail wheelers or nose wheel fairings.
Aircraft Unloading:
Chock the aircraft first if necessary. Disconnect the strut strap or “J” hook
from the aircraft and secure the winch strap to the tug. Gently pull the tug away from the aircraft.
General Maintenance
Tire Pressure:
The tire pressure can range from 30 psi for lighter aircraft in the 3,000 pound range
to 70 psi for heavier aircraft up to 16,000 pounds.
Battery:
Keep the battery fully charged. Chargers are available by calling Airtug at 216-941-9781.
Hydrostatic Transaxle:
This should occasionally 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 to tighten the drive belt if
necessary. Simply loosen the nuts, push the engine plate towards the rear of the tug and tighten the
nuts firmly.
