ASSEMBLY OF THE METAL SHIELD
DANGER:
The metal shield must be
properly installed on the tool anytime the tool
is used with the blade. The forward tip of the
metal shield helps to reduce the occurrence
of blade thrust which can cause serious injury
such as amputation to the operator or by-
standers. Failure to install the shield in the
position shown can result in serious injury to
the operator. The length of the shield must be
aligned with the length of the tube.
DANGER:
The blade is sharp and can
cut you. Be sure to wear gloves while working
with blades.
