• To increase depth of cut raise the table:to decrease
depth of cut lower the table.
• Tighten the table lock knobs.
• When planingseveral pieces of wood, plane all the
lumber with the same set-up to have uniformthick-
ness removed.
A depth of cut limiter (Figure 19, Key No. 38) is
provided to limit depth of cut to maximum of 'At
Do not make planing outs deeper than _,V'.
ADJUSTING BLADE HEIGHT
Refer to Figures 6, 7 and 19,
CAUTION: Planer blades are very sharp. Use laather
gloves to protecthands from injury and exercise caution
when adjustingblades.
WARNING: Disconnectplaner from power source
before adjustingplaner.
To produce even surface on a workplace,the blade
edges must be the same distancefrom axis of cutter-
head. The blade height comes adjusted from the factory
and would not raqulra any adjustment.However,if
adjustments are required;
• Loosen and remove hex washer head boltsand hex
head bolts (Key Nos. 10 and 5) and removechip
chute (KeyNo. 69).
• Loosen and remove hex washer head bolts(Key No.
10) and remove chipbraaker cover (Key No. 68).
• Loosen five gib screws (Key No. 14) on the cutter-
head to loosen the cutterheadgib (Key No. 13).

• Position the knife gauge assembly on the cutterhead
so that both the legs of the gauge rest firmly on the
cutterhead. Remove chip deflector plate (Key No, 7)
if required.
• The blade edge must just make contact with the tab
on the knife gauge. Adjust blade height by turning
the jack screw (Key No. 15),

Rgure 7 - Checking Blade Height
• Repeat the previoustwo steps to adjustthe blade
height on the other end of the blade.
• Secure blade and glb bytighteninggib screws.
Tighten outside gib screwsfirst, and then, working
towards center, tighten the remaininggib screws.
• Repeat the above steps for remaining blades.
Securely tighten all gib screws.
• Replace chipdeflector plate.
• Replace cutterheadcover.
• Replace chip chute.
PREPARING THE WORK
• Do not plane dirty boards. Dirt and small stones are
abrasive and will wear the blade.
Remove nails and staples to avoiddamaging the
blades.
• Avoid knots. Heavy crossgrain makes knots hard.
Also knots san come loose and jam the blade.
• The planer works best when the lumber has at least
one flat surface. Use a surface planer or jointer to
m
define a flat surface.
• Twisted or severely warped boards can jam the
planer. Rip lumber in half to reduce the magnitude
of the warp.
FEEDING WORK
• Feed work along the grain direction. Wood fed
against the grain will result in chipped and splintered
edges. Sometimes grain will switch direction in the
middle of a length of board. If possible, cut board
before planing (See Figure 8).
