A1: Planing, stock thickness below
75mm
A2: Edge jointing
A3: Planing of narrow gibs
A4: Planing of short stock with push
wood.
6.2 Thicknessing
Correct operating position:
To feed the work piece into the
machine, position yourselves offset to
one side of the feed opening.
Work piece handling
Adjust the planer table to the work
piece thickness.
Feed work piece slowly and straight
into the thicknesser. It will then be
automatically fed through the
thicknesser.
Guide work piece straight through the
thicknesser.
To remove the work piece from the
machine, position yourselves offset to
one side of the outfeed opening.
Support long work pieces with helping
roller stands.
Operating notes:
Always use sharp cutter knives!
Feed with thicker work piece end at the
front, hollow side downward.
Max. 4,5 mm depth of cut. If a work
piece gets stuck lower the planer table
by app. 1mm (1/4 crank turn).
Plane the stock with the grain, if
possible.
You get a better surface when planing
several passes with less chip removal.
Switch machine off if no further
planning is to be done immediately
afterwards.
Work pieces shorter than 150mm may
not be processed.
Machine max. 2 work pieces at one
time. Feed on both outer sides.
7. Setup and adjustments
General note:
Setup and adjustment work may only
be carried out after the machine is
protected against accidental starting.
Push the E-stop button
Pull the mains plug!
7.1 Changing cutterblock knives
The given instructions about knife
installation, maximum knife circle,
minimum knife clamping width and
correct knife lock blot tightening torque
must strictly be observed.
The cutter knives may only be
changed when the mains plug is
pulled!
Risk of personal injury by cuts from the
cutter knives. Wear suitable gloves
when changing cutter knives.
Move cutter block cover to front and
fence to back.
Turn the four square-hear bolts of the
cutter knife lock bar all the way in
(wear gloves!).
At first remove cutter knife, then cutter
knife lock bar from the cutter block.
Clean all surfaces of cutter block and
cutter knife lock bar with a suitable
solvent (do not use cleaning agents
that could corrode the light metal
components).
Use only suitable cutter knives
conforming the technical specification
and EN 847-1
Unsuitable, incorrectly mounted, dull,
cracked of bent cutter knives can work
loose or increase the risk of kickback
considerably.
Always replace all three cutter knives
at once.
The cutter knife lock bars are balanced
to each other and thus can randomly
be placed.
Only cutter knives marked “HSS” or
“HS” can be resharpened!
When resharpening, remove the same
amount of material from all three cutter
knives, otherwise a balancing error
may cause damage to the bearings.
Cutter knives can only be resharpened
down to a minimum width of 15 mm.
Knives may not exceed the cutterblock
body by 1,1mm in radius.
Use genuine Jet replacement parts
only.
Place the cutter knife lock bar in the
cutterblock´s groove. Turn the four
square-head bolts so far that the cutter
knife will just slide in.
Insert a sharp cutter knife and adjust
position with the cutter knife lock bar,
so that neither protrudes over the edge
of the cutter block.
Adjust the knives according to the knife
setting gauge (S) resting on the
outfeed table.
Fig 10
When turning the cutter block, the
adjustment gauge must move with the
cutter block knife by the width of the
groove.
Fig 11
Micro adjust the jack screws (T) with a
3mm alan key.
To tighten the cutter knife, start
tightening with the two outer bolts. Do
not extend the tool (U) when tightening
the bolts, do not tighten bolts by
striking the wrench.
Reset fence and cutter block guard.
