SPECIFIC SAFETY RULES FOR JOINTERS
WARNING: When using the planer, these safety precautions
should also be followed to reduce the risk of personal injury.
1. Keep cutterhead sharp and free of all rust and pitch.
2. Always use a push block when jointing stock that does not give a
reasonable distance of safety for your hands.
3. Never put hands directly or over the cutterhead.
4. Always make sure that exposed cutterhead behind the fence is
guarded, especially when jointing near the edge.
5. Do not perform jointing operations on material shorter than 8"
(203,2 mm), narrower than 3/4" (19 mm), or less than 1/4" (6,35 mm).
6. Do not perform planing operation on material shorter than 8"
(203,2 mm), narrower than 3/4" (19 mm), wider than 4" (101,6 mm)
or thinner than 1/2" (12,7 mm).
7. Maintain the proper balance between the infeed and outfeed
table surfaces and cutterhead knife path.
8. Keep the work piece adequately at all times during operation.
Maintain control of the work at all times.
9. Do not back the work toward the infeed table.
10. Do not attempt to perform an abnormal or little-used operation
without studying and a proper use of adequate hold - down/push
blocks, jigs, fixture, stops, etc.
11. Do not make cuts deeper than 1/8" (3,18 mm) in a single pass. On
cuts more than 11/2" (38,1 mm) wide, adjust depth of cut to 1/16"
(1,6 mm) or less to avoid overloading the machine and to minimize
the chance of kick-back.
ADJUSTMENTS & OPERATION INSTRUCTIONS
REAR TABLE AND KNIFE ADJUSTMENT
For accurate work in most jointing operations, the rear table must
be exactly leveled with the knives at their highest point of revolu-
tion. This means, of course, that the knives must be parallel to the
table and project equally from the cutterhead.
To check this alignment proceed as follows:
1. Disconnect the jointer from the power source.
2. Raise or lower the rear table as required by turning the rear table
hand lever, until the rear table is exactly leveled with the knives of
the cutterhead at their highest point of revolution.
3. Place a straight edge on the rear
table, extending over the cutterhead
as shown in figure 1.
4. Rotate the cutterhead by hand. The
blades should just touch the straight
edge. If a knife is too low or too high
at either end , loosen the lock screws
in the knife slightly, shift the knife
until it just touches the straight edge,
and tighten the screws securely.
After the rear table has been set at the correct height, it should
not be changed except for special operations and after sharpening
knives.
If the rear table is too high, the result
will be as shown in figure 2 and the
finished surface will be curved.

When the rear table is too low the
condition will be as illustrated in fig-
ure 3, the work piece will be gouged
at the end of the cut.
As a final check of the rear table ad-
justment, run a piece of wood slowly
over the knives for 6" (152,4 mm) to
8" (203,2 mm); it should rest firmly
on both tables, as shown in figure
4, with no open space under the fin-
ished cut.
ADJUSTING TABLE GIBS
"Gibs" are provided to take up all play between the mating dovetail
ways of the base and the front and rear tables of your jointer. The
"gibs" are located between the dovetailed way of the front and rear
tables at the base. Proper gib adjustment is necessary for the correct
functioning of the jointer. The"gibs"on your machine were adjusted
at the factory and should require no further adjustment, however,
if it ever becomes necessary to adjust the "gibs" proceed as follows:
1. To adjust the outfeed table "gib",
loosen all three gib adjusting screws
(1) at figure 5, and make sure the rear
table lock screw (2) is loose.
2. Proceed to retighten the three gib
adjusting screws (1) starting with the
lowest screw first and as you proceed
toward the top, raise up gently on
the outboard edge of the table being
adjusted.
This will offset any tendency of the table casting to "droop" or
"sag" and permit the gib to be brought up to a good secure fit. The
infeed table "gib" is adjusted in the same way.
IMPORTANT: Do not leave the screws too loose, it should take a
little bit of effort to crank the table up and down. Your jointer is a
finishing machine and you can't expect to get a very good jointer
finish if the table is set loose and sloppy.
SETTING KNIVES
If the knives are removed trom the head for replacement or regrind-
ing, resetting them as follows:
1. DISCONNECT THE MACHINE FROM POWER SOURCE.
2. Place a knife in its groove so that the rear edge of the bevel is
1/16" (1,6 mm) from the surface of the cutterhead.
3. Silo lock - bar into place and tighten lock screws tightly.
4. Place a knife setting bar made of
a piece of hardwood, approximately
12" (304,8 mm) long, jointed straight
on one edge, on the rear table, as
shown in figure 6.
5. Rotate head backwards by hand and
adjust blade until it just touches the
bar.
6. Using the bar, check blade at each end so that it is parallel to the
table top and tighten the screws.
7. Insert the other two knives and repeat above instructions.
OPERATION
The following directions will give the beginner operator a start on
jointer operation. Use scrap pieces of lumber to cheak settings and
to get the feel of the operation before attempting regular work.
Always use guard and keep hands away from cutterhead.
