Abstract
A router power tool having a housing and a base, the housing mounted to be moveable with respect to the base. The base and housing are connected by first and second extendable assemblies, at least one of the assemblies including biasing means to bias the housing away from the base. This extendable assembly has a control portion which can be moved, while located with the extendable assembly, from a first position in which the biasing means provides the biasing force and a second position in which the biasing means is released. In one embodiment, the router power tool includes safety stop portions to prevent movement of the tool holder while cutting tool changing is being performed. In another embodiment, a safety stop portion limits movement of at least one of the extendable assemblies when the cover is held by the power switch when in the on position.
