Direction Of Feed And Thrust; Operation - Craftsman 315.175170 Operator's Manual

DIRECTION OF
FEED AND THRUST
See Ftgures 18- !9.
The muter motor and cutter revolvein a clockwise direc-
tion. This gives the tool a alight tendency to lwist In a
counterclockwise direction, especially when the motor
revs up.
Feed the router into the workpiece from left to right.When
fed from left to right, the rotationof the cutter pulls the
router against the workpieca. If fed in the opposite direc-
tion, the rotation of the spinning cutter will tend to throw
the router away from the workplace causing kickback.
This could cause you to lose control of the muter.
Because of the high speed of cutter rotationduring a
proper feeding operation, there is very little kickback
under normal conditions. However, if the cutter stdkes a
knot, hard grain, or foreign object that affects the normal
progress of the cutting action, there will be a slight kick-
back. The direction of kickback is always in the direction
opposite cutter rotation. This will affect the trueness of
your cut.
To guard against kickback, plan your setup and direc-
tion of feed so that you will alwaysbe thrusting the tool in
the same direction that the leading edge of the cutter is
moving. The thrust should be in a direction that keeps the
sharp edges of the cutter continuouslybiting straight into
new (uncut}wood.
NOTE: For best results, make sure to take enough tlme to
set up for cutting. While cutting, make sure to use the proper
rate of feed.

When routinga groove, your travel should be in a direc-
tion that places the guide you are using at the right-hand
side. When the guide is pos'_'+oned as shown in the "guide
inside" illustration,tool travel should be from left to right
and counterclockwisearound curves.When the guide
is positionedas shown in the "guide outside" illustra-
tion, tool travel should be from right to left and clockwise
around curves. If there is a choice, the first setup is gener-
ally the easier to use. In either case, the sideways thrust
you use is against the guide.
