NOTICE

Do not attempt to increase wear life by welding on cutting edges. This may result in premature failures. Change or rotate the cutting edges or router bits, before the mounting surfaces become worn.

Note: Any material that might fall on the worker should be removed from the elevator and from the sides of the bowl.

Park the machine on level ground. Engage the parking brake.
Raise the bowl and block up the bowl. Block the bowl on both sides. Blocks should be of material that is suitable for carrying the weight of the bowl. Only block up the bowl to a sufficient height for the removal of the cutting edges.
