CALIBRATING
AND USINGTHE
DIGITAL DISPLAY
To calibrate the display "A":
Set the preset depth control knob at 1" (see Figure 15,
page 7).
Plane a piece of scrap wood to 1". Check wood thickness
with caliper to ensure wood thickness, preset stop and dig-
ital display match. If the wood thickness and preset stop
do not correspond, calibrate the preset stop prior to cali-
brating the digital display. See "Maintenance", page 12.
Remove button 'A', and using a punch or other suitable
object, insert into the button hole and press. The display
A will read 1.0000" or 25.4 mm. (see Figure 17).
To use depth of cut display "B":
Feed workpiece through planer, taking a shallow cut.
Depress button 'B', which will set display B to zero (0).
Lower rollercase until desired depth of cut is shown on
display "B".
Feed workpiece and repeat.

PREPARE
WORK
*
Thickness planer works best when lumber has at least
one flat surface.
*
Use surface planer or jointer to create a flat surface.
°
Twisted or severely warped boards can jam planer. Rip
lumber in half to reduce magnitude of warp.
°
Work should be fed into planer in same direction as the
grain of the wood. Sometimes grain will change directions
in middle of board. In such cases, if possible, cut board
in middle before planing so grain direction is correct.
CAUTION:
Do not plane board which is less than 15" long;
force of cut could split board and cause kickback.
PLANING
WARNING:
Always turn the planer off and disconnect it from
the power source whenever blade cover is removed. Never
operate planer without the blade cover properly secured.
The planer is supplied with planing blades mounted in the
cutterhead and the infeed and outfeed rollers adjusted to the
correct height. The planer is capable of working at two differ-
ent feed rates. Feed rate refers to rate at which lumber travels
through planer. Planing can be done at 22 FPM (standard
planing) or at 11 FPM for an improved surface finish (see
Feed Rate Adjustment).
°
Position rollercase to produce the depth of cut desired.
°
Operator is responsible for aligning work so it will feed
properly.
°
Lift edge to infeed side of the table by grasping edges
of board at approximately middle of length.
°
Boards longer than 24" should have additional support
from free standing material stands.
°
Position the workpiece with the face to be planed on top.
°
Turn the planer on.
°
Rest board end on infeed table and direct board into planer.
°
Gently slide the workpiece into the infeed side of the planer
until the infeed roller begins to advance the workpiece.
°
Let go of the workpiece and allow automatic feed to
advance the workpiece.
°
Do not push or pull on workpiece.
°
Move to the rear and receive planed lumber by grasping
it in same manner as it was fed.
CAUTION:
Do not stand directly in line with front or rear
of planer.
°
Do not grasp any portion of board which has not gone
past out-feed roller.
°
Repeat this operation on all boards which need to be
same thickness.
Planer has return rollers on top so assistant can pass work
back to operator (see Figure 18).
