OPERATION
The towbar units works and the principle that you need to press the wheels to
the round by pressin the handle. Otherwise it is impossible that the APT4000
of about 30 k (64 Lbs) can pull an aircraft of more than 1000 k . It is
important not to proceed fast initially, the aircraft has a certain inertia, so let the
airplane move first and then increase the speed by turnin the control handle.
The selector is to select forward or backwards, Left is forward, ri ht is
backwards.
By turnin the black handle, you select the speed of the unit. From 1 km/h up to
7 km/h.

Speed control , by turnin the handle speed is increasin Selector forward
and backwards.
THIS HANDEL IS FIXED TO CONTROL HANDLE BY 3mm key.
HINTS
1. KEEP CORRECT PRESSURE IN ALL TIRES FOR MAXIMUM OPERATION.
2. MOVE MAIN GEAR TIRES OVER RAILS AND DOOR TRACKS AT A SLIGHT ANGLE ONE,
MAKES TOWING EASIER
