RECEIVING THE PLANER
ST AND ASSEMBL Y
Carefully unpack the planer and any loose items
from the wood crate and inspect for damage. Any
damage should be reported to your distributor and
shipping agent immediately. Before proceeding
further, read your manual thoroughly to familiarize yourself with proper assembly, maintenance
and safety procedures.
Remove the screws that hold planer to the shipping crate. Remove the protective coating from
the table, bed rolls, feed rolls, cutterhead and loose
items packed with the machine, including lifting
handles and motor pulley. This coating may be
removed with a soft cloth moistened with Kerosene. DO NOT use acetone, gasoline or lacquer
thinner for this purpose. DO NOT use solvents on
plastic parts.
CAUTION: Use care when cleaning the
cutterhead as knives are very sharp.
INSTALLATION & ASSEMBLY
For best planing performance, locate planer on
solid, level foundation and anchor to the floor with
good quality lag screws:
1. With machine in position, test table surface lengthwise and crosswise with machinist
level. Place metal shims under low corners.
2. Check that all four corners are supported,
then tighten lag screws.
3. Re-test level of table surface in both directions, and adjust if necessary.
TABLE EXTENSION ROLLERS
Mount the table extension rollers to the table using the provided hex hd. screws (A) and washers,
Figure 3. The rollers should be adjusted before
using the planer, see "Adjusting Table Extension
Rollers" pg. 8.
LIFTING HANDLES
There are four lifting handles, Figure 2, furnished
with the machine. If any type of sling is used to lift
the machine, be sure to attach to lifting handles
only. Make sure machine is kept in level position
while lifting. The lifting handles can be pushed
back in when not in use.
FIGURE 3
MOTOR, MOTOR PULLEY & BELT
1. Assemble the motor pulley (A) to the motor shaft by aligning it with the key in the shaft,
and tighten the screw (B) in the motor shaft, as
shown in Figure 4.
FIGURE 2

FIGURE 4
2. Assemble the motor to the motor mounting plate (B), using the provided hardware (A), Figure 5.
FIGURE 5
3. Using a straight edge, align the motor pulley (D) and cutterhead pulley (E) as shown Figure
6. The motor plate can be moved for alignment
by loosening the set screws (C) in the motor plate
(B) as shown in Figure 5.
FIGURE 7
FIGURE 6
4. Assemble the belts to the two pulleys, Figure 6. Adjust for the proper belt tension by raising
or lowering the motor plate (F), Figure 7, then
tighten the nuts (G). Proper tension is obtained
when there is approximately 1/4" deflection of the
center span of the pulleys by using light finger pressure, Figure 8.
FIGURE 8
ADJUSTMENTS
TABLE ROLLER ADJUSTMENT
Your planer is supplied with two table rollers (A),
Figure 9, which turn as the stock is fed into the
planer , thus reducing friction. It is not possible to
give exact dimensions on the proper height setting of the table rollers because each type of wood
behaves differently.
As a general rule, however, when planing rough
stock, the table rollers should be set at high position. When planing smooth stock the rollers should
be set at low position.
NOTE: When raising the roller higher above the
table, the range is from .003" to .006", see Figure
10.

FIGURE 9
FIGURE 10
The table rollers are factory set for average planing and are parallel to the table surface. If you
desire to adjust the table rollers higher or lower,
proceed as follows:
1. Disconnect machine from power source.
2. Lay a straight edge (B), Figure 11, across
both rollers.
3. On one side of the table, loosen the screws
(C) with an Allen wrench, and turn the eccentric
shafts (D) to raise or lower the rollers.
4. When the proper height is achieved,
tighten screws (C).
5. Adjust the rollers from the opposite side
of the table in the same manner.
FIGURE 11
ADJUSTING TABLE EXTENSION
ROLLERS
Place a straight edge over the extension rollers
and the table, as shown in Figure 12, to make sure
the extension rollers and the table are at the same
height.
If necessary, adjust the table extension rollers as
follows:
1. Loosen the screws and washers (A) to
move the table extension roller to the proper position, then retighten the screws.
2. Adjust both front and rear extension rollers in the same manner.
IMPORTANT: Be sure that the height of front and
rear rollers are the same. The table rollers must
always be set parallel to the table.

FIGURE 12
ADJUSTING DEPTH OF CUT
The cutting depth scale is a combination inch/metric scale (A), Figure 13, with a cutting range from
0 to 8" (204mm). The distance of upward or downward movement is controlled by the handwheel
(B). One revolution is .059" (1.5mm). Before
moving the table up or down, loosen the lock nuts
(C). After obtaining the proper table position,
tighten the lock nuts (C).
FIGURE 13
KNIFE ADJUSTMENT
When checking or adjusting the cutterhead knives,
proceed as follows:
1. Disconnect machine from power source.
2. Remove the six screws (A) and remove
upper cover (B), Figure 15.
CUTTERHEAD ADJUSTMENT
Although your planer was carefully adjusted at the
factory , it should be checked before being put into
operation. Any inaccuracies due to rough handling in transit can easily be corrected by following these directions.
To check the adjustments you will need a straight
edge, feeler gauge, and a home-made gauge
block made of hardwood. This gauge block can
be made by following the dimensions shown in
Figure 14.
FIGURE 15
3. To check and adjust knives, use the provided knife gauge (C) and check all four knives,
Figure 16. Knives should just contact the bottom
of the center protrusion (D) of the knife gauge.
FIGURE 14
FIGURE 16
4. If an adjustment to one or more of the
knives is necessary, slightly loosen the knife gib
(E), Figure 16, by turning the six locking screws
