DEPTH OF CUT
To control the depth of cut, use the crank handle located on
the top of the machine to raise or lower the head assembly
and you can read the depth of cut in inches and metric on
the depth of cut scale. See figure-6.
One revolution of the hand wheel lowers or raises the head
assembly approximately 5/64" (2mm). The depth of cut
depends on the hardness of the wood and the width of
the board being passed under the cutter head. It is
recommended not to cut more than 1/32" of the material in
one single pass. Generally a series of light cuts will give a
better result than trying to cut too much material in a single
pass.
WORK-PIECE INSPECTION
This planer is designed to cut wood only, do not cut any kind
of metal, stone or glass.
Before planing the stock, make sure to inspect it for nails,
staples, small pieces of stone or metal and any other foreign
objects which could come in contact with the knives.
If the wood contains any of these objects and it comes in
contact with the cutter head knives, the object might cause
kick back or damage the knives. For optimum results, always
inspect your work-piece carefully before you plan and wear
eye protection.
PLANING TIPS
For improved surface finishing with minimal tearouts, always
feed the work-piece with the grain.
The work-piece should be fed into the planer so that
the blades are travelling with the grain as they finish the cut.
The grain should be angled up towards the rear of the
work-piece as it is fed into the cutter head.
BASIC OPERATIONS
This section explains the basic operations of your
KN AP-125B planer.
TO USE THE PLANER:
Make sure you have read and understood the instructions
given in this manual before operating the planer.
Wear safety glasses and a face shield.
Use a jointer and flatten one surface of the work-piece before
planing.
Place the work-piece on the table with its flat surface down.
Use the crank handle and lower the cutter head assembly so
that the edge of the cutter just touches the work-piece.
Rotate the crank handle slightly less than 1/4 turn to raise
the cutter-head above the work-piece surface approximately
1/32" for the first pass, then remove the work-piece from
the machine.
Crank
handle
Some woods with excessive twisting or wrapping are
un-stable while planing and are dangerous because during
the operation the work-piece can move unexpectedly which
will either damage the blade or injure the operator. One face
of the twisted stock should be surfaced on a jointer.
Some stocks with large knots are also dangerous to plane.
Do not remove more than 1/32" of material in a single pass.
If you are planing long lumber, get the help of an asssistant
or use a roller stand to provide support for the work-piece.
Scrape all glue off joined boards before planing.
Plane only natural wood fibers. Do not plane wood
composites.
Connect the cord to the power source and turn the machine
ON.
Stand to one side of the planer and feed the work-piece with
its flat surface down, into the machine.
Make sure not to push or pull the workpiece during operation.
The infeed and outfeed rollers will control the feed rate of
the work-piece.
Once the work-piece is clear of the out-feed roller, measure
the work-piece thickness.
If further planing is needed, rotate the crank handle
counterclockwise slightly less than 1/4 turn to lower
the cutter head assembly and cut the work-piece.
