Basic Thickness Planer Operations (continued)

Thickness Stop (Repeat-A-Cut) Adjustment

1. Pull the Repeat-A-Cut knob straight out to remove.
2. Remove the screw on the right side of the Repeat-A-
Cut scale and remove the cover.
3. Measure the height from the base to the cutter head
knife tip. This can be done with a scrap piece of board
— 1-1/2" for example.
4. Use the elevation handwheel to adjust the height to the
known thickness piece of scrap, then remove the piece
of scrap without moving the handwheel.
5. Make sure the Repeat-A-Cut is on the 1-1/2" setting
and loosen the lock nut on the adjustment bolt. Adjust
the bolt to come in full contact with the step block and
tighten the lock nut.
6. Replace the Repeat-A-Cut cover and secure it with the
screw.
7. Replace the knob.
8. Plane a workpiece and check its thickness. Repeat
procedure, if necessary.

Checking for Worn Knives

The condition of knives will affect the precision of the cut.
Observe the quality of the cut the planer produces to
check the condition of the knives.
Dull knives will tear, rather than sever wood fibers, and
produce a fuzzy appearance.
A raised ridge will occur when dull knives pound on wood
that has a varying density.

Maintenance

The planer will operate best if it is kept in good condition.
Keep the unit adjusted as described in the "Operation"
section. Also, the knives must be kept clean and sharp to
ensure the quality of cut and efficiency of operation.
Knives are "double edged". When one side becomes dull
they may be turned over and the opposite edge used.
WARNING: To reduce the risk of injury from unex-
pected starting or electrical shock. Make certain
that the unit is disconnected from the power
source, before attempting to service, or remove
any component.

Lubrication

Motor and cutter head bearings are sealed and need no
lubrication. Height adjustment guides and elevation
screws should be cleaned of debris and greased when
needed.
Occasionally apply a few drops of light machine oil to the
four support rods to keep the carriage sliding smooth.

Cleaning the Knives

Gum and pitch will collect on knives and cause excess
friction when working. Knives will overheat and wear at
If a raised ridge is produced running the length of the
workpiece, the knives have been nicked. If the nick is
small, shift one knife to the right and the other to the left.
(see "Replacing Knives" section).
For knives replacement and installation refer to "Replac-
ing Knives" section.
an accelerated rate. Remove knives and clean with a
gum and pitch remover to keep knives clean.

Cleaning The Feed Rollers

Excessive gum, pitch and sawdust can reduce friction of
the rubber rollers. Use alcohol to wipe the rollers.

Motor Ventilation

Check the motor vents periodically while planing and
clear away any sawdust to avoid motor heating.

Changing Brushes

WARNING: To reduce the risk of electrical shock,
fire or injury, use only parts identical to those iden-
tified in the parts list. Reassemble exactly as origi-
nal assembly to reduce the risk of electrical
hazards.
The carbon brushes furnished will last approximately 50
hours of running time or 10,000 on/off cycles. Replace
both carbon brushes when either brush has less than 1/4"
length of carbon remaining. To inspect or replace first
unplug the planer. Then turn the brush caps counterclock-
wise to remove. To reassemble reverse the procedure.
Tighten the brush caps snugly but do not overtighten.
