G0675 10" Jointer/Planer Combo Machine
Spring Tension
Feed roller spring tension must be adjusted so
that feed roller pressure is uniform for planer
operation. Roller spring tension will vary, depend-
ing on the type of wood you plane. This is usually
determined from trial-and-error.
Generally speaking, less spring tension is more
forgiving on workpieces. Therefore, if you primar-
ily plane milled lumber with relatively consistent
surfaces, you can get away with having less
spring tension. If you mainly plane rough lumber
with inconsistent surface heights, more spring
tension is a must to keep the workpiece feeding
through the planer without stopping.
If workpieces regularly stop feeding during opera-
tion, it may be a sign of weak spring tension.

To adjust feed roller spring tension:
1. DISCONNECT THE JOINTER/PLANER
FROM THE POWER SOURCE!
2. Set up the machine for planer operations,
remove the cap screws that secure the front
and back access panels to the frame (see
Figure 44 on Page 33), then remove the
panels.
3. Move the chain tensioner away from the
chain and place a 5mm hex wrench into the
hole in the frame, as shown in Figure 73, to
hold the tensioner and de-tension the chain.
6. Remove the hex wrench, move the tensioner
back to re-tension the chain, the re-install the
front and rear panels with the cap screws you
removed earlier.
7. Run a test board through the planer.
— If the workpiece slips when you feed it,
repeat Steps 1-4, then turn the hex nuts
1
⁄2
to 1 turn clockwise to increase spring ten-
sion. Continue to Step 8.
— If the workpiece is abruptly grabbed when
initially fed into the planer, repeat Steps
1-4, then turn the hex nuts
1
⁄2 to 1 turn
counterclockwise to decrease spring ten-
sion. Continue to Step 8.
— If the workpiece feeds smoothly, the spring
tension is correct.
8. Repeat Steps 6-7, and continue adjusting the
spring tension until it is right for the type of
wood you are planing.

4 Locate the hex nuts and springs on both
sides of the feed rollers, as shown in Figure
73.
5. Adjust the hex nuts so they are at the recom-
mended factory setting —
1
⁄2" (13mm) from the
bottom of the feed roller bolts (see Figure
74).
