ADJUSTING
BLADE
HEIGHT
Refer to Figures 10 and 11.
CAUTION:
Make sure the switch is in the "OFF" posi-
tion and cord is unplugged before proceeding with
checking blades.
The blades have been adjusted at the factory to assure
proper operation and should require no adjustment.
However, shipping and handling may have caused mis-
alignment. For accurate cutting, the blades must be
0.003" higher than the outfeed table when positioned at
the highest point. To check blade height:
Block the blade guard from closing using a scrap
piece of wood about 4-1/," long between the fence
and blade guard.

Turn the cutterhead so that one of the blades is at
the highest position.
CAUTION:
The cutterhead blades are extremely
sharp. Do not let your fingers contact the cutting edge
at any time.
Place a straightedge over the outfeed table and the
blade.

The straight edge must touch evenly on the outfeed
table at both ends of the blade.
Turn the cutterhead slowly, and check if the blade
lightly touches the straight edge.
If the straightedge raises, loosen the blade lock
screws and gently tap the blade with a piece of
scrap wood. If the blade does not touch the straight-
edge, loosen the blade lock screws and raise the
blade by prying the lower edge of the blade against
the outfeed table using a screwdriver.
Tighten blade lock screws.
AVOID DAMAGE TO BLADES
Jointer/planer is a precision woodworking machine and
should only be used on quality lumber. Using bad lumber
could result in a poor quality cut on subsequent pieces.
For proper operation, it is preferable to use the jointer with
a dust collecting system (see "Using a Vacuum Hose",
page 8) attached to the exhaust port in the rear of the
jointer. Attaching a dust collecting system is especially
required when taking deeper cuts to prevent clogging of
wood chips.
Do not use dirty boards. Dirt and stones are abrasive
and will wear blade.
Remove nails and staples. Jointer should only cut wood.
Avoid knots. Heavy cross-grain makes knots hard
and they can come loose and jam the jointer.
Assess value of badly warped boards. Operator can
be tempted to use too deep of cut to square boards
quickly. Use several passes to maintain a level surface.
ON-OFF
SWITCH
Refer to Figure 12.
The operating positions of the "On-Off" switch are locat-
ed on the front of your jointer/planer.

On and

to be locked in the "Off" position.

FEEDING

blades. An even feed will produce a uniform service. To
feed workpiece:
Hold the board firmly down on both tables and
against the fence.
Keep fingers close together.
