Replacing the anti-tipper wheels

Requirements:
● Small flat screwdriver
● Two 13 mm socket wrenches
Uninstalling an anti-tipper wheel:
●
Carefully remove the black plastic cap (3) from the middle of the anti-tipper wheel (2) with a
small flat screwdriver.
●
Loosen the self-securing axle nut, which is located underneath the plastic cap (not visible in
the illustration) using a 13 mm socket wrench. Secure the axle (4) against slippage using a
second 13 mm socket wrench.
●
Remove the axle nut and the washer.
●
Pull the wheel (2) off of the axle.
●
Replace the wheel and/or the ball bearing.
The ball bearings are inserted in the wheel. They can be removed using a small screwdriver.
Installing an anti-tipper wheel:
●
Assemble the parts in reverse order.
●
When installing the ball bearings, make sure you do not forget to insert the distance sleeve
between the ball bearings.
●
When repositioning the wheel on the axle, make sure you do not forget the spacer washer (5).
●
Tighten the self-securing axle nuts just tight enough that the wheel can still rotate without
resistance. When rotated very quickly, it must not start to wobble.
