and on to the piece of scrap wood.
5. Feed the planer at a uniform and reasonable
rate that does not put excessive strain on
the motor or blades, (do not pull the planer
back over the surface already cut.)
6. Use progressive cuts until you are near the
desired depth, and then re-adjust to a thin
cut for the final pass to obtain a good
surface finish.
The motor may stall if
improperly used or
overloaded. Reduce the pressure (feed rate)
or depth of cut to prevent possible damage to
the tool if the motor labors.

DEPTH OF CUT AND FEED RATE
The cutting depth (planing depth) is
determined by the difference in height between
the adjustable front shoe and the fixed rear
shoe of the planer. The depth knob adjusts the
front shoe, which retracts and exposes the
blade and determines the amount of material
removed from the workpiece. The cutting
depth range is from 0 to 3/32" (2.6 mm) per
pass. (Fig. 1)
The appropriate depth of cut and feed rate
depends on the workpiece material:
To avoid clogging and/or damage to the motor,
a thinner cut and/or a slower feed rate may be
needed if the material has any of these
characteristics: hardness; gumminess,
sappiness, moisture, paint, varnish and/or
knots. Also, when planing against the grain or
across the grain rather than with the grain, a
shallower cut and/or slower feed rate is
required. Whenever possible, test by planing a
similar piece of scrap material.
Use multiple, progressive cuts to achieve the
total desired depth.
Start with a thin cut. If the plane moves freely
through the workpiece with no excessive load
on the motor, the depth setting can be
increased before the next cut.
When near the desired total depth, re-adjust
the planing depth to a thin setting for the final
cut to obtain a good surface finish.
Adjusting the Depth of Cut: Rotate depth
adjustment knob until the indicator is aligned
with the desired cutting depth on the depth
scale (Fig. 1).
