Figure 12 - Return Rollers
Planer has return rollers (A) on top so assistant can
pass work back to operator.
NOTE: Assistant must follow same precautions as
operator.
Surface that the planer will produce will be smoother
if shallower depth of cut is used.
Avoiding
Snipe
Snipe refers to a depression at either end of board
caused by an uneven force on cutterhead when work
is entering or leaving planer.
Snipe will occur when boards are not supported
properly or when only one feed roller is in contact
with work at beginning or end of cut.
To avoid snipe, gently push the board up while feed-
ing the work until the outfeed roller starts advancing
it.
Move to the rear and receive planed board by gently
pushing it up when the infeed roller looses contact
with the board.
When planing more than one board of the same
thickness, butt boards together to avoid snipe.
Snipe is more apparent when deeper cuts are taken.
Feed work in direction of grain. Work fed against
grain will have chipped, splintered edges.

Planer will operate best if kept in good condition and
properly adjusted.
CHECK FOR WORN BLADES
Condition of blades will affect precision of cut.
Observe quality of cut which planer produces to
check condition of blades.
Dull blades will tear, rather than sever wood fibers
and produce fuzzy appearance.
Raised grain will occur when dull blades pound on
wood that has varying density. Raised edge will also
be produced where blades have been nicked.
Blades on this planer are reversible. Blades should
always be reversed or replaced as matched set.
Keeping a spare set of blades on hand is recom-
mended.
CHANGING
BLADES
Refer to Figures 14-17, page 9.
WARNING:
Always turn planer OFF and disconnect
from power source before starting any maintenance
work.
Loosen and remove socket head bolts (A) from
blade guard (B) on the rear side of planer. Remove
blade guard.
