• Beveling refers to cutting the entire edge of a board
at an angle. Beveling may require several passes
due to the depth of cut needed.
• Chamfering refers to removing only the comer of the
edge of a board. Normally a chamfer Is made on one
pass; so a '/,e" depth of cut Is marie.

USING A VACUUM HOSE
A standard dust collection hose can be attached to the
exhaust port (2 _h" Die.) on the rear of the Jointer.Jolnter
will perform properly at all depths of cuts up to '/," when
used with a dust collecting system. {See "Avoid Damage
to Blades', page 7.) To attach a dust collecting system:
• Insert the dust collection hose to the exhaust port on
the rear of the jointer.
• Turn the dust coJlecting system on.
• Turn the Jotnter on.
• Periodicallyreplace/empty bag in dust collection system.
If the blades are nicked they must be replaced or
reground. They can be reground several times until they
become '_lte"wide.
NOTE: Many shops do not have capabilities to resur-
face blades. Yellow pages should list "Sharpening
Services" or "Tool Grinding:
Figure 17 • Sharpening Blades
Never Install unbalanced blades or reground blades
less than '_/." wide.
REPLACING BLADES
Refer to Figures 18 and "_g.pages g _nd 10.
• Unplug the jolnter/planer from power source and turn
the switch to "OFF" position.
• Block the blade guard from closing down.
• Loosen and remove three blade lock screws secur-
ing blade and blade clamp.
WARNING: Turn the switch to "Off" position and
unplug jointerlptaner from power source before pro-
ceeding to do maintenance work,
CHECKING FOR WORN BLADES
Condition of blades will affect precision of cut. If blade
wear is not observed when checking the btade height,
the quality of cut will indicate the blade condition. Dull
blades will tear rather than sever wood fiber. A raised
grain will occur when dull blades pound on wood where
there is difference in density, A raised ridge will be pro-
duced where the blades have been nicked.
SHARPENING BLADES
Refer to Figure 17.
The blades can be honed individually by whetting them
with a fine sharpening stone. Make sure oilstone is fiat
and is cot worn. To sharpen blades:
• Partially cover the stone with paper to protect the
table top.
• Position in_=ed table so stone will contact blade
along its beveled surface.
• Stroke the stone across blade from one side to other
while stone is also moved slightly in the direction of
feed.
• Make sure to do the same number of atTokeson
each place.

Figure 1B • Block Blade Guard
• Lift blade and blade clamp from cutterhead
• Clean any sawdust and resin buildup from cutter-
head and blade clamp.
• Place blade clamp against the replacement blade
and replace In cutterhead.
• Secure blade and blade clamp using three blade
lock screws. Do not tighten blade lock screws.
NOTE: Check blade height at both ends of blade (see
Adjusting Blade Height, page 7).
• Tighten blade lock screws.
• Recheck blade edJus_nent and make sure blade is
still level with ou_eed table.
• Repeat the procedure to replace the other blade.
• Remove the scrap wood and release blade guard.
• Make sure all the i_ada lock screws are tight and snug.
