ANTI-KICKBACK PAWLS
Refer to Figure 19,
The anti-kickback pawls (Key No. 21 ) prevent the work-
piece from kicking back against the direction of feed.
The pawls must rotate freely to ensure safe operation
of the planer.
• Inspect the anti-kickback pawls daily for proper oper-
ation checking that the pawls rotate freely.
• Clean the pawls of all gum and chips as required to
ensure safe operation.
TABLE ROLLER ADJUSTMENT
Refer to Figure 20.
The table rollers (Key No. 59) are free-spinningrollers
that help reduce friction, makingthe planingoperation
smoother.
The proper height of the table rollers is dependent upon
the hardness and surface finish of the work, piece:
• The roller height shouldbe adjusted so that the
workplace feeds smoothlythroughthe planer but is
not damaged by the table rollersor by the feed
rollers.
• Rough cut wood requiresthe rollersto be adjusted a
littlehigher, while smoothfinish wood requiresthe
rollersto be a little lower.
• For all workplace materials and finishes the table
rollersshould be positionedslightlyabove the table.
• Table roller height Is adjusted by looseningset
screws (Key No. 73) and rotatingeccentricadjusters
(Key No. 57).
• Use a straight edge acrossthe table and table
rollersto check miler adjustment.

• Be sure that both ends of the table rollersare at the
same heightso that the rollersare parallel with the
table and secure eccentricadjusterswith set screws
(Key No. 73),
ADJUSTMENT BLOCK
Refer to Figure 13.
Some of the maintenance adjustmentsrequire the use
of a handmade adjustment block (See Figure 13).
Make this block out of hard wood scrapwith the
dimensionsshown. Exact dimensionsare not critical
but a very smooth, level finish acrossthe top Is
required.
OUTFEED ROLLER HEIGHT ADJUSTMENT
Refer to Figures 14, 15, 19 and 20.
The outfeed roller (Figure 19, Key No. 35) is set at the
factory so that the outfeedroller Is positioned 1ram
belowthe blade.The outfeed rollershouldneed no
further adjustment but can be checkz_d and adjusted
usingthe following procedures:
• Disconnect planer from power source.
• Adjust bladeheight properly(See "Adjusting Blade
Height".page 7).
• Place adjustmentbiock(Figure 13) under cutterhead
at one end as shownIn Figure 14. Place 1ramfeeler
gauge between blockand blade. Raise or lower table
so that blade just contactsfeeler gauge when blade
is at lowest position. Put gearbox in neutraland rotate
cutterhead slowlyto determine lowestposition of
blade.Locktable in position _ tighteninglockknobs
(Figure20, KeyNo. 75). Do not unlocktable position
untilboth sidesof ouffeedrollerhave been adjusted.
