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 heightof the table rollers is dependent upon

the hardnessand surfacefinishof the work,piece:

• The roller height shouldbe adjusted so that the

workplacefeeds smoothlythroughthe planer butis

not damaged by the table rollersor by the feed

rollers.

• Rough cut wood requiresthe rollersto be adjusteda

littlehigher,while smoothfinishwood requiresthe

rollersto be a little lower.

• For all workplacematerials and finishesthe table

rollersshould be positionedslightlyabove the table.

• Table roller heightIs 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 withthe

table and secureeccentricadjusterswith set screws

(Key No. 73),

ADJUSTMENT BLOCK

Refer to Figure 13.

Some of the maintenance adjustmentsrequire the use

of a handmadeadjustmentblock (See Figure 13).

Make this block out of hard wood scrapwiththe

dimensionsshown.Exactdimensionsare notcritical

but a very smooth,levelfinishacrossthe top Is

required.

OUTFEED ROLLER HEIGHT ADJUSTMENT

Referto 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 adjustmentbut can be checkz_dand adjusted

usingthe following procedures:

• Disconnect planer from power source.

• Adjust bladeheight properly(See "Adjusting Blade

Height".page 7).

• Place adjustmentbiock(Figure13) under cutterhead

at one end as shownIn Figure 14. Place 1ramfeeler

gauge betweenblockand blade.Raise or lower table

so that blade justcontactsfeeler gauge when blade

is at lowestposition. Put gearboxin neutraland rotate
