4. Tighten jam nut.
Move your fence
forward, then back
against the stop. Re-
check the stop bolt
(Fig.10a).
WARNING: Jointer knives are dangerously
sharp. Use extreme caution when handling
knives or working near them. Serious personal
injury may occur.
After completing the job, you should tighten
all the bolts that you have installed, then in-
stall the dust collect hood.
OPERATION INSTRUCTIONS
OPERATION
The following directions will give the beginner
operator a start on jointer operation. Use scrap
pieces of lumber to check settings and to get
the feel of the operation before attempting
regular work.
IMPORTANT: ALWAYS USE GUARD AND
KEEP HANDS AWAY FROM CUTTERHEAD.
PLACEMENT OF HANDS DURING FEEDING
At the start of the cut, the left hand holds the
work firmly against the front table and fence,
while the right hand pushes the work toward
the knives. After the cut is under way, the new
surface rests firmly on the rear table as shown
in figure 11.
The right hand pushes the work forward and
before the right hand reaches the cutterhead it
should be moved to the work on the rear table.
NEVER PASS HANDS DIRECTLY OVER THE CUT-
TERHEAD.
JOINTING AN EDGE
This is the most common operation for the
jointer, set the guide fence square with the
table. Depth of cut should be the minimum
required to obtain a straight edge, hold the
best face of the piece firmly against the fence
throughout the feed.

JOINTING WARPED PIECES
If the wood to be jointed is dished or warped,
take light cuts until the surface is flat. Avoid
forcing such material down against the table;
excessive pressure will spring it while passing
the knives, and it will spring back and remain
curved after the cut is completed.
JOINTING SHORT OR THIN WORK
When jointing short or thin pieces, use a push
block to eliminate all danger to the hands.
Two types are
shown in figure
12 they are easily
made from scrap
material.
DIRECTION OF GRAIN
Avoid feeding work into the jointer against
the grain as shown in figure 13, the result will
be chipped and splintered edges.
Feed with the grain as in figure 14 to obtain a
smooth surface.
BEVEL
To cut a bevel, lock the fence at the required
angle and run the work across the knives while
keeping it firmly against the fence and table,
several passes may be necessary to arrive at,
the desired result.
When the angle is small, there is little differ-
ence whether the fence is tilted to the right or
left, however, at greater angles approaching
45 degrees, it is increasingly difficult to hold
the work properly when the fence is tilted to
the right. The advantage of the double tilting
fence is appreciated under such conditions.
When tilted to the left, the fence forms a v-
shape with the tables, and the work is easily
pressed into the pocket while passing it across
the knives. If the bevel is laid out on the piece
in such direction that this involves cutting
against the grain, it will be better to tilt the
fence to the right.
