4) When desired height setting is reached, tighten lock nuts in
position. (Fig.9)
5) Reassemble side and top covers and replace height
adjustment handle.
NOTE: Remove guage block before starting machine.

ish as well as thickness is best accomplished by taking light
cuts on the board. Always feed the material so the planer
blades cut with the grain of the board.
This allows the blades to sever the fibres of the wood instead
of lifting and tearing the fibres resulting in a fuzzy appearance
to the surface. Feeding against the grain
can also cause the knife to lift large chips
from the surface of the board, causing
unsightly appearance.
THICKNESS PLANING

Thickness planing is the sizing of the material to a desired
thickness, while creating a smooth surface parallel to the
opposite side of the board.
The art of thickness planing consists mainly of using good
judgement about the depth of cut in various situations. You
must take into account:
1) The width of the stock
2) The hardness of the board
3) The dampness of the board
4) The straightness of the board
5) The grain direction
6) The grain structure
How these factors can effect the quality of the work can only
be learned through experience. Whenever working with a new
type of wood, or one with unusual problems, always make
test cuts on scrap material prior to working on the actual
piece.

FOR ADDITIONAL PLANING

If additional planing is needed to obtain the desired thickness
or finish, hand crank the cutterhead no more than 3mm (at any
one time) and complete another pass.
WARNING: Never plane more than 3mm in one
pass and never attempt to plane a board under
127mm (5") in length. Always wear a
protective face shield.
LUBRICATION
The recommended lubrication for roller chains used in medium
to slow operation is to simply wipe the chain clean. When
there is an excess build up of dust or wood shavings etc., coat
chain with a light film of oil but never pour the oil directly on
the chain. Over-oiling tends to hasten the collection of dust
and woodshavings and works them into members of the chain
leading to increased wear and premature replacement. This
applies to the speed reduction and height adjustment chains
as well as the elevation screws.
The bearings on the cutterhead are factory lubricated and
sealed. They require no further attention.

PERIODIC MAINTENANCE

Build-up of sawdust and other debris can cause your machine
to plane inaccurately. Periodic cleaning is mandatory for
precision planing and highly recommended.
Close fitting parts, such as the lockbars and the planer
cutterhead slots, should be cleaned with a brush; removing
clinging foreign matter. Then replace all parts in their
respective positions slightly dampened with oil.
Remove resin and other accumulations from feed rollers and
table with a non-flamable solvent.
