G0633/G0634 Jointer/Planer Combo Machine
Symptom Possible Cause Possible Solution
Excessive snipe
(gouge in the end
of the board that is
uneven with the rest
of the cut).
1. Outfeed table is set too low.
2. Operator pushing down on trailing end of
workpiece.
3. Workpiece is not supported as it leaves the
planer.
1. Align outfeed table with cutterhead knife at top dead
center ( Page 18).
2. Reduce/eliminate downward pressure on trailing end
of workpiece.
3. Support the workpiece as it leaves the outfeed end
of the planer.
Workpiece stops/
slows in the middle
of the cut. 1. Taking too heavy of a cut.
2. Table not parallel with head casting.
3. Pitch and glue build up on planer compo-
nents.
1. Take a lighter cut.
2. Adjust the table so it is parallel to the head casting
( Page 50).
3. Clean the internal cutterhead components with a
pitch/resin dissolving solvent.
Chipping (consistent
pattern). 1. Knots or conflicting grain direction in wood.
2. Nicked or chipped knife or carbide insert.
3. Taking too deep of a cut.
1. Inspect workpiece for knots and grain direction; only
use clean stock.
2. Replace the knife or rotate/replace affected insert
( Page 43 or 45).
3. Take a smaller depth of cut. (Always reduce cutting
depth when surface planing or working with hard
woods.)
Fuzzy grain. 1. Wood may have high moisture content or
surface wetness.
2. Dull knives or inserts.
1. Check moisture content and allow to dry if moisture
is too high.
2. Rotate/replace the knives or inserts ( Page 43 or
45).
Long lines or ridges
that run along the
length of the board 1. Nicked or chipped knives or inserts(s). 1. Replace or offset knives or rotate/replace inserts
( Page 43 or 45).
Uneven knife or
insert marks, wavy
surface, or chatter
marks across the
face of the board. 1. Knives not adjusted at even heights in the
cutterhead.
2. Carbide inserts not installed evenly.
3. Worn cutterhead bearings.
1. Adjust the knives so they are set up evenly in the
cutterhead ( Page 43).
2. Make sure carbide inserts do not have debris under
them; make sure inserts are torqued down evenly.
3. Replace cutterhead bearings.
Glossy surface.
(Planer)
1. Knives or carbide inserts are dull.
2. Cutting depth too shallow.
1. Rotate/replace the knives or inserts ( Page 43 or
45).
2. Increase the depth of cut.
Chip Marks (incon-
sistent
pattern).
(Planer)
1. Chips aren't being properly expelled from
the cutterhead.
1. Use a dust collection system
Board edge is con-
cave or convex after
jointing. (Jointer) 1. Board not held with even pressure on infeed
and outfeed table during cut.
2. Board started too uneven.
3. Board has excessive bow or twist along its
length.
4. Insufficient number of passes.
1. Hold board with even pressure as it moves over the
cutterhead.
2. Take partial cuts to remove the extreme high spots
before doing a full pass.
3. Surface plane one face so there is a good surface to
position against the fence.
4. It may take 3 to 5 passes to achieve a perfect edge,
depending on starting condition of board and depth
of cut.
