Removal

1. Remove the MAC 5000 and all loose items from the trolley and then

place the trolley on its side.

2. Locate the slot under the arrow on the bearing dust cap and using a

small blade screwdriver, pry the cap from the caster to be removed.

3. Using an Allen wrench, remove the wheel shaft and wheel from the

caster.
