Fence Slide
Lock Handle
Both the infeed and outfeed table use a leadscrew,
guided by adjustable wear plates.
Release the position locking by loosening the
T-handle bolt (Key No. 43).
Raise and lower the table by turning handwheel (Key
No. 31 ).
Make sure that action is constant for entire length of
travel. There should be a slight drag.
To adjust drag loosen set screws and nuts (Key Nos.
27 and 42). Adjust set screws until a slight drag on
table action is felt. Then hold set screw in position
and tighten nut.
After drag is adjusted and table is in desired posi-
tion, secure table in position by tightening T-handle
bolt.
POSITIONING
INFEED TABLE
Refer to Figure 14.
The position of infeed table determines depth of cut.
Infeed table also needs to be lowered to make certain
adjustments.
Positive stop prevents the table from being lowered
more than '/8" (Key No. 16).
Table can be lowered past the stop (for rabbeting
operation, etc.) by simultaneously
pulling knob out-
ward and turning table handwheel.
ADJUSTING
BLADE
HEIGHT
Refer to Figure 14.
To produce an even surface on a workpiece, the blade
edges must be the same distance from axis of cutter
head. A blade gauge (Key No. 60) has been provided to
make blade height adjustment easy.
Lower the infeed table as far as it will go.
Place the blade gauge so that it rests on the cutter
head and straddles the blade.
Loosen the five locking bolts (Key No. 6).
Press the blade gauge firmly against the cutter head
and make sure that the blade touches the contact
points.
If blade does not touch contact points or gauge does
not touch cutter head, use the jack screws (Key No. 4)
to adjust blade accordingly.
Tighten the bolts to secure the blade in position.
RABBETING
The jointer blades have a second blade on the outward
radial edge. These edges must also be aligned to per-
form rabbeting.
Make sure blades protrude the same distance from
end of cutter head. The blades should not protrude
more than 1/8".
Use the blade gauge when repositioning blades to
keep them adjusted as described in "Adjusting Blade
Height".
By repositioning the infeed table and fence, a wide
range of rabbet joints can be cut.
WARNING:
Rabbeting requires removal of blade guard.
Blade guard must be replaced correctly when rabbeting
is completed. (See Assembly, "Mount Blade Guard")
ADJUSTING
OUTFEED
TABLE
The outfeed table supports the wood after it has been
cut. Outfeed table will be set about .003" below the
level of blade edge. The wood is compressed at the cut
and the outfeed table must be adjusted to compensate
for it.
Raise outfeed table above height of blade.
Position one blade edge point to the highest point on
its path.
Rest a straightedge on the table.
Lower outfeed table until blade and straightedge
contact.
Gently rotate cutter head and allow it to move the
straightedge. Blade should pull the straight edge with
out visibly lifting it from the table.
Make sure all blades move the straightedge the
same amount. Also check both sides of blade. If all
blades do not line up, blade height should be read-
justed.
Lock outfeed table position with the T-handle bolt
(Figure 14, Key No. 43). Position should not need to
be changed.
Proper adjustment of outfeed table can also be
determined by examining the cut (See Figure 9,
page 10).
