
WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories.
An accidental start-up can causeinjury.
Periodic Maintenance
1. Routinely check the tool for damage or brokenparts.
2. Clean the unit of dust and debris that has collected
in all accessible areas of the planer from planning
woodmaterial.
3. Wipe off infeed and outfeedrollers.
4. Clean base table. Light waxing will help wood material
pass through theplaner.
5. Evaluate blade sharpness condition. Replace
asnecessary.
6. Gauge Calibration, check thickness gauge calibration
and turret stopcalibration.
7. Check brushes for wear and replace asnecessary.
Changing the Planer Knives

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect tool from
power source before making any adjustments or
removing/installing attachments oraccessories.
Your planer is equipped with a three-knife cutterhead with
three blades that have two sharpened edges. These blades
can be rotated once and changed asneeded.
Change Blades When
• Dull – may cause feedingissues.
• Slow feed or nofeed.
• Motor overloading can also be an indication that knives
are dull and result in frequent breakertrips.
• Excessive tearout of the wood material being planed.
• Nicked – blades can become nicked when planning
very knotty wood or when foreign material is not
removed from the wood beingplaned.
To Change Planer Knives (Fig. S–W)
1. Use the T-wrench to remove the tool tray. The
cutterhead should now be exposed. If the eight bolts
in the knife clamp ARE NOT visible, use a piece of
scrap wood to carefully rotate the cutterhead until the
bolts are accessible and the cutterhead lock lever
15
engages as shown in FigureS. This will prevent
further rotation of the cutterhead as you change each
knife (Fig.T). If the bolts ARE visible, be sure that the
cutterhead locking lever is engaged so the cutterhead
does not rotate while you are changing the knives. To
do this, use a piece of scrap wood to attempt to rotate
the cutterhead. The locking lever will click into place if it
is not alreadyengaged.
