USING HOLD DOWN/PUSH
BLOCKS
Refer to Figure 15
Always use hold-down/push-blocks
when jointing, or
rabbeting wood that is narrower than 3", planing
wood thinner than 3"
Figure 15 - Feeding with Push Blocks
Grasp the hold-down/push-blocks
firmly
Position the push-blocks flat on top of workpiece and
push the workpiece down against the table
Use a hand-over-hand
motion to maintain control
over the workpiece at all times
When planing workpiece between 1__ 3/4.and nar-
rower than the push-blocks, tilt the push-blocks so
that it clears the cutterhead guard while feeding
BEVELING
AND CHAMFERING
Refer to Figure 16.
The fence on the jointer/planer
is adjustable to 45 °
outward Adjust the fence to the desired angle and
tighten fence lock knobs
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 corner of the
edge of a board Normally a chamfer is made on one
pass; so a _/_6" depth of cut is made
Bevel Edge
WARNING:
Turn the switch to "Off" position and
unplug jointer/planer 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 blade 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
The blades can be honed individually by whetting them
with a fine sharpening stone Make sure oilstone is flat
and is not worn To sharpen blades:
Partially cover the stone with paper to protect the
table top
Position infeed 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 strokes on
each blade
If the blades are nicked they must be replaced

USING A VACUUM
HOSE
A standard dust collection hose can be attached to the
exhaust port on the rear of the jointer Jointer will per-
form properly at all depths of cuts up to %/' when used
with a dust collecting system To attach a dust collecting
system:
Insert the dust collection hose to the exhaust port on
the rear of the jointer
Turn the dust collecting system on
Turn the jointer on
Periodically replace/empty
bag in the dust collecting
system
Figure 17 - Block Blade Guard
Always replace blades in sets of two.
REPLACING
BLADES
Refer to Figure 17.
Unplug the jointer/planer from power source and turn
the switch to "OFF" position
Block the blade guard from closing down
Loosen and remove four blade clamp screws secur-
ing blade and blade clamp
Lift blade and blade clamp from cutterhead
Clean any sawdust and resin buildup from cutter-
head and blade clamp
Place new blade onto pins on cutterhead
Place blade clamp over blade and secure in position
with screws
