5. Transport and start up
5.1 Transport and installation
The machine is designed to operate in
closed rooms and must be placed
stable on firm and levelled ground.
The machine can be bolted down if
required.
Fold the infeed and outfeed rollers up
when the planer is not in use and
during storing.
Wrap the power cord around the
hangers under the infeed table(Fig2)
Fig 2
For packing reasons the machine is
not completely assembled.
5.2 Assembly
If you notice any transport damage
while unpacking, notify your supplier
immediately. Do not operate the
machine!

must be connected to a dust extractor.
5.5 Starting operation
You can start and stop the machine
with the ON/OFF-button(A).
Fig 4
In case of machine overload the motor
overload cut-off (B) will react.
After appr.5 min of cooling the
overload cut off can be reset.
Attention: The machine will start
when you reset the overload push
button!
6. Machine operation
Correct operating position:
To feed the workpiece into the
machine, position yourselves offset to
one side of the feed opening.
Workpiece handling:
Adjust the planer table to the
workpiece thickness.

Fig 5
Feed workpiece slowly and straight
into the thicknesser. It will then be
automatically fed through the
thicknesser.
Guide workpiece straight through the
thicknesser.
To remove the workpiece from the
machine, position yourselves offset to
one side of the outfeed opening.
Support long workpieces with helping
roller stands.
Operating notes:
Always use sharp cutter knives!
Feed with thicker workpiece end at the
front, hollow side downward.
Max. 2,5mm depth of cut.
If a workpiece gets stuck raise the
cutterhead by app. 1mm (1 crank turn).
Plane the stock with the grain, if
possible (Fig 6).
Fig 6
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.
Workpieces shorter than 250mm may
not be processed.
Machine max. 2 workpieces at one
time. Feed on both outer sides.
7. Changing cutter knives
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.
Knife removal:
Raise the cutterhead to its highest
position.
Remove the thickness crank (E) and
the planer cover screws(K).
Fig 7
Remove the planer cover.
Remove the cutter block cover (L)
Fig 8
Turn the hex-head bolts (M) of the
cutter knife lock bar all the way in
(wear gloves!).
Fig 9
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).
Knife installation:
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 both 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 both cutter
knives, otherwise a balancing error
may cause damage to the bearings.
Cutter knives can only be resharpened
down to a minimum width of 14 mm.
Use genuine Jet replacement parts
only.

Fig 10
Place the cutter knife lockbar (N) in the
cutterblock´s groove.
Make sure the springs (P) are in place.
Turn the hex-head bolts so far that the
cutter knife will just slide in.
Insert a sharp cutter knife (O) and
adjust position with the cutter knife
lockbar, so that neither protrudes over
the edge of the cutter block.
Use the knife setting gauge (Q) to
adjust the knife.
Fig 11
To tighten the cutter knife, turn the
hex-head bolts (M) of the cutter knife
lockbar.
Start tightening with the two outer
bolts. Do not extend tool when
tightening the bolts, do not tighten
bolts by striking the wrench.
Install the cutter block cover, planer
cover and adjustment crank after knife
changing has been completed.
Connect to the dust extraction system.
8. Maintenance and inspection
Make all machine
adjustments or
maintenance with the
machine unplugged from
the power source.
Clean the machine regularly
Inspect the proper function of the dust
extraction daily.
Defective safety devices must be
replaced immediately.
Before starting any work, check the
mobility of the anti-kickback fingers
(must fall down by their own weight).
Changing of brushes:
Disconnect from power source, unplug!
Inspect the brushes after 50 hours of
use.
Fig 12
If the brushes are worn to 3mm
replace them.
