2. INTRODUCTION & SPECIFICATION
Steel and cast aluminium construction.
Measures toe-in and toe-out by contact with wheel rims and using optical sight to align markers.
Works on practically all cars and light commercial vehicles with rim diameters between 200mm and 600mm.
3.1. ASSEMBLY.
Your gauge has been supplied in flat pack form for quick and easy assembly.
3.1.1 Take each ready assembled side frame in turn and slide on the balance leg (fig.1.8). Slide the balance leg back onto the alignment peg
and tighten the thumbscrew.
3.1.2 Place the two frames opposite each other with each extended bar portion positioned to the right hand side. The frame nearest to you is
the one to which the periscope (fig. 1.3.) unit should be attached.
3.1.3 Place the periscope unit onto the tube and slide it to the left until it stops against the end of the tube. Tighten the two thumb screws on
the back of the unit to secure it to the main bar. Attach the target plate (fig. 1.4.) to the periscope using the screws supplied.
3.1.4 Slip the mirror unit (fig. 1.2.) onto the main bar of the other frame and tighten the thumb screw to secure it.
3.1.5 Attach a contact bar (fig. 1.1.) to each of the upright arms. Firstly loosen the thumb screw on the contact bar holder and place through
the upright arm. Slide the square portion of a contact bar through the holder, tighten the thumbscrew to secure.
3.1.6 Each contact bar may be fitted either to the left or the right of its respective support arm. This is to allow the gauge to handle all tyres
on 8 to 24 diameter rims and to allow close contact when required e.g. when in use on a vehicle lift.
3.2. CALIBRATION.
The gauge will be calibrated each time it is used as part of the process of checking wheel alignment. Calibration will be
done with the two halves of the gauge facing each other with the contact bars touching.
