• Check accuracy oftest cut priorto working on fin-

ished product.

AVOID DAMAGE TO BLADES

• Thickness planer/molder is a precision woodworking

machine and should be used on qualitylumber only.

• Do not plane dirty boards;dirt and small stones are

abrasive and wear out blade.

• Removenails and staples.Use planer/molderto cut

wood only.

• Avoid knots. Heavily cross-grained wood makes

knots hard. Knots can come loose and jam blade.

CAUTION: Any article that encountersplaner/molder

blades may be forciblyejectedfrom planer/moldercreat-

ing dsk of injury.

AVOIDING SNIPE

• Snipe refersto e depression at either end of board

caused by an unevenforce on cutterhead when

work is entering or leaving planer/molder.

• Snipe occurs when boards are not supported prop-

erly or when only one feed rolleris in contact with

work at beginningor end of cut.

• To avoid snipe on the lead edge of the workpiece,

adjust the infeed table up slightlyabove hodzontaL

• To avoid snipe on the trailingedge of the workpiece,

adjust the ouffeed table up slightlyabove horizontal.

• When planing more than one board of the same

thickness, butt boardstogether to avoidsnipe.

• Snipe is more apparent when deeper cuts are taken.

• Feed work in direction of grain.Work fed against

grain will have chipped, splintered edges.

MOLDING

Molding, also known as millworkor trim, can be defined

as a stripof wood milledwith a plain or decorativesur-

face which is continuous throughoutits length.

• Toget superior moldingfinish, workpieca must be

planed and presized pdor to molding.Always presize

the workpieca to within ',_,"of the finalthickness

prior to molding.

• During moldingoperation, do not exceed I/,, total

depth of cut.

Certain molding profiles require outer edge clean-up.

When using such profiles the workpieca must be pre-

sized to t_,, larger than the finalwidth.This will allow '1,,"

for clean-up on either side.

Certain moldingprofiles cut only the edge of workpieca.

When using such profilesworkpieca must be presized

to the same width as the final width.
