Changing Fuses
Disconnect planer from power source, and open
the electrical enclosure. Pull open the cover on
a fuse holder, as shown in Figure 7, and slide
out the old fuse. Replace it with a new one of
the proper amperage. Close the cover.
Do not use a fuse with
amperage rating different than what is listed
on the cover of the fuse holder.
Changing Knives
The planer has a Tersa
TM
Monobloc cutterhead.
Knife changing is simple, and the two-sided
knives are self seating once the cutterhead
begins rotating. Tersa
TM knives are available
from your dealer or most woodworking supply
stores.
Do not loosen any screws on
the cutterhead.
1. Push brake release button (see Figure 5).
The brake release light will come on.
2. Pull out on the lever at the right side of the
machine, and raise the hood.
After prolonged use of the
planer, the cast iron frame and areas around
the cutterhead may be hot.
3. Disconnect machine from power source.
4. Rotate the cutterhead to gain access to a
knife. Use the provided brass punch to
gently tap down the segmented gibs, as
shown in Figure 8. This will release the
knife.
5. Align the knife and carefully slide it through
the hole in the side of the bearing casting
(Figure 9).
6. To install a new knife (or the same knife
reversed for a new edge), insert it through
the hole. Make sure the knife is properly
seated upon the bead (Figure 8) and the
ends are not protruding past the ends of the
cutterhead. When the machine is started
later, the gibs will automatically secure the
knife in place.
7. Repeat this procedure for the other three
knives.
8. Lower the hood and reconnect power to the
machine. Press the brake release button
(Figure 5). The warning light will go out.
