Abstract

In order to achieve an improved chip and shaving ejection in a portable per, a small portion of the motor cooling air stream is diverted and directed through an air passage into a chip ejection channel. The volume flow of this chip ejection air stream may be controlled by a control slider gate to suit various operating conditions. The chip ejection air stream also serves to cool the drive belt and planing head. The diverted air flow keeps the chips in a sufficiently loose state to assure an effective, clog-free ejection of chips. Furthermore, a deflection flap is used in the chip ejection channel to eject the chips to either side of the tool as desired.
