CAUTION:
• Always lower the main frame when aligning the indi-
cator plate with the graduation indicating the
desired finished dimension. If you raise the main
frame into the desired finished dimension, addi-
tional play in the screw may result. This may cause
an undesired finished dimension.
• Always place the workpiece flat on the table top
when predetermining the depth of cut. Otherwise,
the predetermined depth of cut will differ from
actual depth of cut.
Depth adjusting gauge

Use the depth adjusting gauge when you need to prede-
termine the depth of cut more accurately. To do so, pro-
ceed as follows.
1. First, plane the workpiece at the predetermined
depth of cut. Measure the thickness of the planed
piece to know how much more stock you need to
remove.
2. Turn the depth adjusting gauge on the crank handle
until the 0 graduation is aligned with the groove on
the tool.
3. Now turn the crank handle counterclockwise until
the graduation for the desired depth of cut is
aligned with the groove on the tool.
4. When you need to remove more than the amount
specified in the table mentioned in the "Adjusting
depth of cut" section, set the depth of cut shallower
than the amount and make two or more passes.
Stopper
Use the stopper when you need to plane many work-
pieces to the same thickness. To do so, proceed as fol-
lows.

1. Turn the crank handle until the indicator plate points
to the scale graduation indicating the desired fin-
ished dimension.
2. Depress the stopper button and lower the stopper
until it just contacts the table top.
3. If you need fine adjustment of the stopper, turn the
stopper knob.
CAUTION:
• When the stopper is not in use, always raise it to
the topmost position. Never force the crank handle
when the stopper is in contact with the table top.
This may cause tool damage.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Replacing planer blades
CAUTION:
• Handle the blades very carefully when removing or
installing the blades to prevent cuts or injury from
the blades and to prevent damage to the blades.
They are razor-sharp.
• Clean out all chips, dust, pitch or foreign matter
adhering to the drum or blades before installing the
blades.
• Use blades of the same dimensions and weight , or
drum oscillation/vibration will result, causing poor
cutting action and eventually, tool breakdown.
• Replace both blades at the same time.
• The disposable-type blade has a cutting edge on
both sides. When one cutting edge becomes dull,
you can use the other cutting edge. Always remove
resin and dirt sticking to the reverse side of the
blade before using the other cutting edge. This
blade must not be re-sharpened. When both cutting
edges become dull, the blade should be carefully
thrown away.
1. Removing blades
Loosen the thumb screw which secures the chip cover
and remove the chip cover. Remove the screws which
secure the right side cover. Then remove the right side
cover. Turn the pulley until the drum can be locked in the
position whereby the blade installation bolts face upward.
