Abstract: An exercise treadmill is disclosed which includes various features to enhance user operation and to reduce maintenance costs. These features include handlebars with an upwardly curved center section and outwardly flared side portions along with pivoting rear legs for the treadmill frame. The control panel features include snap-in user trays and an overlay covering the numerical key pad along with an auxiliary control panel having a subset of user controls that are larger and more easy to use than the same controls on the main control panel. Maintenance enhancing features include the provision for access panels in the treadmill housing and a belt lubrication system that uses a priming pulse to clear the wax spraying nozzle. For injection molded parts such as the control panel, structural strength is enhanced by utilizing gas-assist injection molding to form structural ribs. Another feature includes pre-glazing the treadmill belt.

Abstract: The invention provides a guard arrangement including a guard member having an annular base provided with axially spaced apart first and second sets of radially inwardly extending and circumferentially spaced apart projections. The first and second sets of projections are circumferentially aligned and are alignable with axially extending grooves on a tool housing so that the guard member can be slid or snapped on and off the tool housing. To lock the guard member against removal from the tool housing, the tool housing is provided with a pair of annular grooves for receiving the projections on the guard member when the guard member is angularly shifted from a mounting position. To lock the guard member in a desired angular position, the guard member is provided with a finger-operated locking member that is engageable with detents located on the tool housing.
