tyre removal
4.2.1 Lubricate both tyre beads with an approved rubber lubricant.
4.2.2 Place the wheel centrally onto the stand with the narrow bead seat uppermost, slide the two rim clamping jaws, so that they locate on
the rim of the wheel and insert 8mm locking pins. use the crank arm to wind in the adjustable jaw until the wheel is securely fixed.
note: the tyre may require lifting slightly to locate the jaws on the rim, take care not to trap the tyre in the jaws.
note: Figs 9 & 10 shown without tyre to demonstrate the clamping mechanism.
4.2.3 Insert the appropriate centre post through the centre of the wheel into the tyre changer (fig.10).
note: When changing tyres on bearing centre wheels use the centre post which matches the bearing size of the wheel.
For hub-centre wheels the large centre post is used.
4.2.4 Insert the ball end of the tyre bar beneath the top bead and press the opposite side of the bead down into the wheel well with the tyre
bar against the centre post rotate the tool full circle (fig.11) until the bead is lifted above the rim. remove inner tube (if fitted).
