14 USING THE T OOL PROTECTIVE COVER INST ALLA TION CAUTION! The protective cover should be used to prevent the dust and fl ying debris from hitting the operator or from going inside the tool. Failure to do so can shorten the life of the tool and void the limited warranty .
15 ASSEMBLING SPINDLE A TT ACHMENTS CAUTION! Do not leave threaded accessories on the spindle of the tool for extended periods of time, as this may result in making it diffi cult to remove these accessories. Note: The Alpha ® High-Speed Angle Grinder has a 5/8”-1 1 spindle thread .
