Grizzly H7791 Router User Manual


 
Model H7790/H7791 Laminate Trim Router -11-
Performing routing operations in mul-
tiple passes produces smoother results
with less chance of “chip out” and burn-
ing of the workpiece. It also reduces
the possibility of the router jerking out
of your hands from trying to remove too
much material in one pass.
Cutting end grain with the router will
cause tearout. Cutting the end grain
first allows the tearout to be trimmed off
by the side cuts.
Feed the router in a counterclock-
wise direction when routing the outside
edges of a workpiece. Feed the router
clockwise when routing interior holes.
The correct feed speed depends on the
speed of the router, bit size, shape, and
sharpness, and the characteristics of
the workpiece. Feeding the router too
fast will cause chatter marks, chip out,
and possibly damage the bit and motor.
Feeding the router too slow will cause
burn marks and extra build-up on the
router bit. Make a test cut on a sample
scrap of the workpiece to determine the
correct feed speed. A router fed at the
correct speed should make large, thin
shavings.
Once the router bit is installed, the depth is
set, and the feed direction is determined, it
is time to start routing.
To perform routing operations:
1. Secure the workpiece to a stable sur-
face.
2. Place the router flat on the surface of
the workpiece, making sure that the bit
is not touching the workpiece.
3. Firmly grasp the router and turn the
switch ON.
CAUTION: The router will "kick" when
started. If it comes into contact with
the workpiece it could jump out of your
hands and cause injury.
4. Smoothly move the router in the correct
feed direction into the workpiece.
CAUTION: DO NOT start routing at
a corner. Starting at a corner may
cause the router to grab, damaging the
workpiece corner, and possibly causing
personal injury.
5. Feed the router along the workpiece at
a consistent rate of speed. Be aware
of the sound of the router motor and
the sound of the bit cutting. If the motor
begins to bog down, or the sound pitch
of the router bit lowers, reduce the feed
rate.
6. When finished routing, turn the router
OFF, and allow it to come to a com-
plete stop before setting it down.
