Machine Adjustments
The Castle model TSM-21 is designed for use on a wide variety of
materials. You will find that the machine performs well in
hardwoods, softwoods, melamine, particleboard and MDF. The
machine will work on materials of thickness from
½” to 1 ¾”.
Router Feed Rate Adjustment
Figure 4
When switching between materials of different density, it may be necessary to adjust the pocket
router feed rate to achieve optimum performance. In general the desired feed rate is slower for
harder materials.
ƒ The Feed Rate Adjustment knob is located just under the air inlet port on the left side of
the machine as you face it. (Figure 4) This knob is usually locked in place by a nut that
will need to be loosened. Turn the knob as described below to change the router feed
rate:
ƒ Turn clockwise to slow router feed rate.
ƒ Turn counter-clockwise to increase router feed rate.
Caution: The carriage movement is accompanied by a slight “thump” while
cutting, this is normal, but if the “thump” is pronounced and the machine
shutters, this usually means the router feed rate is set too fast.
