Your planer has anx:ker style switch with a removable locklng key to prevent unauthorized
use. If yoU intend to be away from the machine for a long period of time and there is any
chance of its use by others, especially children, remove the locking key with the switch in
the OFf position. Store it in a saf'e. inconspicuous place in your workshop. To tum the
planer on, insenthe red locking key and tum the switch to the ON position. The planerwill
then be operable. To tum the ptaneroff, tum the switch to the OFF positron.

ADJUST DEPTH OF CUT
1. The thickness of stock ruMIn& through the plener Is contmIled by lhe distance you adjust
the cutting knife from the tabl14
2. Always start your work by making 8 light planing cut. The dep1h of cut on subsequent
passes may be increased. up to 3mm. But, remember that .. light cut creates atiner
finish then 8 heavier cut.
3. To adjust the depth ofcut. rum the cuttemead-rajsing hand crank. The depth of cut
adjustment can be read from the depth scale. The adjustment graduation is, 2mm per
revolution of the hand Crank4

ADJUSTING THE DEPT" OF CUT SCALE
For safe operation of your planer. it is very important that the depth
of cut scale is read accurately. To adjust the depth of cut scare. follow the
steps DutUned below:
I. Try to feed a board for planning.
2. Compare the measured thickness of the board to the reading on the depth of cut
scaJe.
3. If the read1n& on the depth of cut scale is Incorrect. loosen the screw whJch tllhtens
the p4astlc pointer and adjust accordingly.
4. When you have properly adjusted the depth of cut scale. test your readina by planing
apiece of scrap lumber. After planing. measure the planed thickness and double
Check it against the scale reading. The two measurements should be the same. If the
measurements are not the same. re-adjust your depth of cut scale to read the
planed U'tickness.

PLIN'N' FOR FINISH
Planing for • smooth finIsh IS well as thiclaless Isbest accomplished by taking light
cuts on1he board. However. several otherthings are importantbesidea Ilaht cutsto
achieve a arnoo1h finish.
AMaya feed 1he board in a direction 1hat allows the planer blades to cut with the grain ..
this aids1he knife in severing the wood fibers rather than lifting .-.d tearifCthe fibers.
Tom fibers gjve afuzzy appearance to the surface. Feeding against the pn can afso
cause your knife to lift large chips from the board's surface. CBUslnl a very unsf&htIY
appearance.
JlleKNESS PLANING
Thickness ~anln& Is the sizing of mate.rial to a deslred thickness. while
c.reating. a smooth surface parallel to the opposite side of the board.
The art of thick.ni!ss planing consIsts mainlyofusing good judgment
about the deDth of cut in various slWatJons,. You must take ,nto account not only the
width of the stock. but the hardness ofthe board, its dampness. straightness. pin
direction and grain structure. .
Tha affects ofthese factors upon the quality of 'the finished work can only
be ... mad 1hrotJgh exPerience. It is always advisable. whenever working
with • new type of wood, or one with unusual problema. to make test
cuts on scrap material Ifpossible prior to working on your finished product
FOR ADDITIONAL PLANING
ffmore materlar needs to be removed, hand crank the cuttemead no mora
than 3mm met complete another pass. Repeat this process until the desired
thickness hasbeen reached.
