Plunge Cuts - Bosch GKM18V-20 Operating/Safety Instructions Manual

All Cuts
Always be sure either hand
does not interfere with the
free movement of the lower guard.
After completing a cut and
the trigger has been re-
leased, be aware of the necessary time it takes
for the blade to come to a complete stop dur-
ing coast down. Do not allow the saw to brush
against your leg or side, since the lower guard
is retractable, it could catch on your clothing
and expose the blade. Be aware of the neces-
sary blade exposures that exist in both the up-
per and lower guard areas.
Only use 5-3/8" metal cut-
ting blades recommended in
this manual. Do not use abrasive wheels. Using
blades not recommended in this manual can re-
sult in a hazardous situation.
Always hold the saw handle with one hand and
auxiliary handle/motor housing with the other.
Always make sure saw foot rests on portion of
work surface that does not drop off.
Maintain a firm grip and operate the switch with
a decisive action. Never force the saw. Use light
and continuous pressure.
This tool is intended for cutting unhardened fer-
rous metal. Refer to the accessories section for
a list of compatible blades based on application.
The following guidelines are to be followed to
reduce the risk of injury:
• Do not cut stacked materials. Cut one piece
at a time.
• Cut at least 1/2" from the edge of the work-
piece
• Do not cut hardened steel.
• Clamp material and cut with the wider edge
of the foot over the clamped side.
• Do not touch the saw blade, workpiece, or cut-
ting chips with bare hands, immediately after
cutting; they may be hot and could burn skin.
• Cut through the thinnest material section; ad-
justing the cutting angle of the blade to do so.
• When cutting is interrupted, to resume cut-
ting: squeeze the trigger and allow the blade
to reach full speed, re-enter the cut slowly
and resume cutting.
