MAINTENANCE

WARNING Turn off the machine and disconnect from
the power supply before conducting maintenance work
or settings.
To change the blades
If the machine planes unevenly or tends to gouge, the blades
must be changed.
To remove the blades, proceed as follows.
• Remove the dust chute.
• Loosen and remove four screws from blade guard on
the rear side of thicknesser. Remove blade guard.
• Carefully turn cutterhead by hand.
• Loosen and remove six bolts from gib.
• Remove gib using magnets provided.
CAUTION Blade edges are extremely sharp. Keep
fingers away from blades at all times.
Press the board against the in-feed table and feed it into
the machine. Release the board when the machine starts to
cut and let the board feed into the machine automatically.
Note. When making repetitive cuts the workpiece can be
passed over the top of the thicknesser utilising
the top rollers
Avoiding snipe
1. Snipe is caused by the board tilting slightly towards
the beginning and the end of the thicknessing operation.
2. It shows as lines at the ends of the board, parallel with
the cutterhead.
3. To avoid snipe, either support the board on extension
tables set to the same level as the in-feed and out-feed
tables, or mount the machine in a recess in the bench
so that the feed tables are level with the bench.
• Blade is located in position by two pins. Gently lift old
blades from cutterhead using magnets. Do not make
contact with the blade using fingers. Use magnet only.
• Reverse or replace blade and carefully position it on
the two pins using magnets.
• Replace gib
and align the
holes on the
gib with holes
on the blade
using magnets.
• Secure gib to
cutterhead
using six bolts
removed
earlier.
