KEMA 1 - Calibration

Calibration step 1

Step 1

Before use attach hose connections to air line. Connect air supply, measure width of the rim with a slide gauge.
Calibration step 2

Activate the air supply button (G), until the jaw is at maximum position and the ram is in ready position.

Step 3

The adjustment screw on the jaw has to be adjusted with a 10 mm Allen key. The distance should be the width of the rim + approx. 2 mm.
Calibration step 4

Step 4

A too large distance between the ram and the jaw means that the ram will be pressed too far out on the side of the tyre, and is therefore unable to grip onto the tyre.
Calibration step 5

Step 5

Too small distance means that the jaw will be locked on to the rim and the machine will be unable to operate (If the machine fastened to the tyre, loosen it using the adjustment screw).
