OPERATING
CONTROLS
ON/OFF SWITCH
Refer to Figure 5.
The ON/OFF switch is located on the front of the planer
motor. To turn the planer ON, move the switch to the up
position. To turn the planer OFF, move the switch to the
down position.
Figure 5 - ON/OFF Switch and Circuit Reset
SWITCH LOCK
Refer to Figure 6.
The planer can be locked from unauthorized use by
locking the switch. To lock the switch:
•
Turn the switch to OFF position and disconnect plan-
er from power source.
•
Pull the key out. The switch cannot be turned on with
the key removed.
NOTE: Should the key be removed from the switch at
the ON position, the switch can be turned off but cannot
be turned on.
•
To replace key, slide key into the slot on switch until
it snaps.

CIRCUIT BREAKER
Refer to Figure 5.
The planer is equipped with a motor protection
device-circuit breaker. The breaker will automatically
shut the planer off when excessive current is consumed.
If the breaker is tripped, turn the planer off and reset
the circuit by pressing the button.
CAUTION:
Be sure to turn the planer off prior to reset-
ting the circuit breaker to avoid unintentional start-up of
the planer.
DEPTH OF CUT
Refer to Figure 12.
Thickness planing refers to the sizing of lumber to a
desired thickness while creating a level surface parallel
to the opposite side of the board. Board thickness which
the planer will produce is indicated by the scale (Key
No. 30).
Depth-of-cut is adjusted by raising or lowering the
rollercase using handle (Key No. 27).
.
Each full rotation of the handle moves the rollercase
1/16
tt
.
Quality of thickness planing depends on the opera-
tor's judgement about the depth of cut.
.
Depth of cut depends on the width, hardness, damp-
ness, grain direction and grain structure of the wood.
.
Maximum thickness of wood which can be removed
in one pass is '/8" for planing operations on work-
pieces up to 6" wide. Workpiece must be positioned
away from the center tab on the rollercase to cut W'.
.
Maximum thickness of wood which can be removed
in one pass is '/,6" for planing operations on work-
piece from 6" up to 13" wide.
CAUTION: A %2"depth-of-cut on hard, softwood 6-13"
wide can be made. However, continuous operation at
this set-up can cause premature motor failure.
.
For optimum planing performance, the depth of cut
should be less than 1/18".
.
Board should be planed with shallow cuts until the
work has a level side. Once a level surface has been
created, flip the lumber and create parallel sides.
.
Plane alternate sides until the desired thickness is
obtained. When half of total depth of cut is taken from
each side, the board will have a uniform moisture con-
tent and additional drying will not cause it to warp.
.
Depth of cut should be shallower when work is wider.
.
When planing hardwood, take light cuts or plane the
wood in thin widths.
.
Make a test cut with a test piece and verify the thick-
ness produced.
.
Check accuracy of test cut prior to working on fin-
ished product.
DEPTH-OF-CUT
GAUGE
Refer to Figure 13.
A spring loaded depth-of-cut gauge (Key No. 23) is
attached to front of rollercase. The pointer on depth-of-
cut gauge accurately displays the depth-of-cut per pass
when workpiece is positioned below the gauge.
Cranking the handle moves the rollercase down and the
pointer shows depth-of-cut up to 3/82"
