W1755 6" Parallelogram Jointer
SERVICE
The Model W1755 comes with both jack screws and
springs inside the cutterhead to provide two options for
adjusting the knives (see
Figure 46).
Note: Only one of these options is needed to set the
knives—Step 5 gives the details.
To adjust/replace the knives, do these steps
:
1. DISCONNECT JOINTER FROM POWER SOURCE!
2. Remove the cutterhead guard from the table and
move the fence back as far as it will go.
3. Open the back cover to expose the cutterhead pul-
ley.
4. Rotate the cutterhead pulley to access one of the
cutterhead knives.
5. Loosen the cutterhead gib bolts (see Figure 47),
starting in the middle, and alternating back and
forth until all of the gib bolts are loose, but not fall
-
ing out.
First Time Only
If this is the first time you are setting the knives,
remove the gibs and knives from the cutterhead.
Decide which adjustment option you are going to use
between the jack screws and the springs.
— If you decide to use the jack screws, remove the
springs from the cutterhead (they are located
directly below the knives).
— If you decide to use the springs, just thread the
jack screws completely into the cutterhead so
they will not get lost.
6. Clean the gibs and clean inside the cutterhead slot
to remove all pitch or sawdust. Coat the knives and
gibs with a metal protectant, then fit the gibs back
in the cutterhead with the new knives.
