G1033 20" Planer
SECTION 2: CIRCUIT REQUIREMENTS
220V Operation
Grounding
The 3 HP G1033 Planer motor is wired to operate at 220V only. A 220V plug that matches your
220V receptacle must attach to the end of the
power cord. Plugs and receptacles can be purchased at your local hardware store or home
center. When connecting to 220V, ensure that
the electrical circuit is in fact a 220V circuit.
Contact your local electrical contractor if uncertain about converting to 220V operation. A wiring
diagram for the motor and switch is provided at
the back of this manual should more detail be
needed.
In the event of an electrical short, grounding
reduces the risk of electric shock by providing a
path of least resistance to disperse electric current. This tool is equipped with a power cord having an equipment-grounding conductor. The outlet must be properly installed and grounded in
accordance with all local codes and ordinances.
When operating at 220V, we recommend using a
NEMA-style 6-30 plug and outlet. See Figure 1.
You may also “hard-wire” the planer directly to
your panel, provided you place a disconnect
switch near the machine.
This equipment must be grounded. Please
ensure that this machine is continuously
grounded from the motor to the machine frame
and then to a known ground. Verify that any
existing electrical outlet and circuit you intend
to plug into is actually grounded. If it is not, it
will be necessary to run a separate 12 A.W.G.
copper grounding wire from the outlet to a
known ground. Under no circumstances should
the grounding pin from any three-pronged plug
be removed. Serious injury may occur.
Extension Cords
Figure 1. Twist-lock style 30A connector.
Fusing
The Model G1033 should be fused at 30 amps.
Fusing at amperage ratings higher than 30 amps
will not adequately protect the motor. You are
cautioned that equipment that is returned to us
for service that shows evidence of being overfused will be repaired or replaced totally at the
customer’s expense, regardless of the present
warranty status.
G1033 20" Planer
We do not recommend the use of extension cords
on 220V equipment. It is much better to arrange
the placement of your equipment and the
installed wiring to eliminate the need for extension cords. Should it be necessary to use an
extension make sure the cord is rated Hard
Service (grade S) or better. Refer to the chart in
Section 1: Safety Instructions to determine the
minimum gauge for the extension cord. The
extension cord must also contain a ground wire
and plug pin. Always repair or replace extension
cords when they become worn or damaged.

Unpacking
Parts Inventory
This planer is shipped from the factory in a carefully packed carton. If you find the machine to be
damaged after you’ve signed for delivery and the
truck and driver are already gone, you will need
to file a freight claim with the carrier. Save the
containers and all packing materials for inspection by the carrier or their agent. Without the
packing materials, filing a freight claim can be difficult. If you need advice regarding this situation,
please call us immediately.
Take a quick inventory of the parts and put them
aside for assembly later. After all the parts have
been removed from the container, you should
have:
The Model G1033 is a heavy machine (770
lbs. shipping weight). DO NOT over-exert
yourself while unpacking or moving your
machine – get assistance. In the event that
your planer must be moved up or down a
flight of stairs, be sure that the stairs are

Clean Up
The unpainted surfaces are coated with a waxy
oil to protect it from corrosion during shipment.
Remove this protective coating with with a solvent cleaner or citrus-based degreaser. Avoid
chlorine-based solvents as they may damage
painted surfaces should they come in contact.
Always follow the usage instructions on the product you choose for clean up.
Many of the solvents commonly used to
clean machinery can be highly flammable,
and toxic when inhaled or ingested. Always
work in well-ventilated areas far from potential ignition sources when dealing with solvents. Use care when disposing of waste
rags and towels to be sure they do not create fire or environmental hazards. Keep children and animals safely away when cleaning and assembling this machine.
Do not use gasoline or other petroleumbased solvents to remove this protective
coating. These products generally have
low flash points which makes them
extremely flammable. A risk of explosion
and burning exists if these products are
used. Serious personal injury may occur.
Some die-cut metal parts may have sharp
edges (called “flashing”) on them after they
are formed. Please examine the edges of all
die-cut metal parts before handling them.
Failure to do so could result in injury.
-8-
Site Considerations
FLOOR LOAD
Your G1033 Planer represents a large weight
load in a small footprint. Most commercial floors
are suitable for the Model G1033. Some residential floors may require additional build up to support both machine and operator.
WORKING CLEARANCES
Working clearances can be thought of as the distances between machines and obstacles that
allow safe operation of every machine without
limitation. Consider existing and anticipated
machine needs, size of material to be processed
through each machine, and space for auxiliary
stands and/or work tables. Also consider the relative position of each machine to one another for
efficient material handling. Be sure to allow yourself sufficient room to safely run your machines in
any foreseeable operation.
LIGHTING AND OUTLETS
Lighting should be bright enough to eliminate
shadow and prevent eye strain. Electrical circuits
should be dedicated or large enough to handle
combined motor amp loads. Outlets should be
located near each machine so power or extension cords are not obstructing high-traffic areas.
Be sure to observe local electrical codes for proper installation of new lighting, outlets, or circuits.
Make your shop “child safe”. Ensure that
your workplace is inaccessible to youngsters by closing and locking all entrances
when you are away. Never allow visitors in
your shop when assembling, adjusting or
operating equipment.

Dust Hood
Switch
The G1033 features a dust hood with a 5'' dust
port. It is only to be used in conjunction with a
dust collection system. Install the dust hood as
follows:
The magnetic ON/OFF switch supplied with the
Planer is pre-wired to the motor. The remaining
step requires connecting the switch to the planer's head casting. To attach the switch:
1. Match the mounting holes on the dust hood
with the tapped holes on the outfeed end of
the cutterhead casting.
1. Align the holes on the flanges at the back of
the switch box with the tapped holes on the
front left corner of the head casting.
2. Using the six M6-1.0 Hex bolts provided,
secure the dust hood to the cutterhead
casting. See Figure 4.
2. Using the socket head cap screws provided, attach the switch box assembly to the
head casting. See Figure 5.
See note regarding the use of a dust collector
and chip deflector adjustment in the adjustment
section of this manual.
The G1033 is shipped without a plug. Now would
be a good time to attach the appropriate plug
specified in Section 2: Circuit Requirements.
DO NOT attach the dust hood if you do not
intend to connect the Model G1033 to a dust
collection system. Accumulated wood chips
could cause a malfunction, resulting in personal injury or damage to the planer.
Do not attempt to make any adjustments to
this machine or perform routine maintenance without unplugging it from its power
source. Serious injury could result.

SECTION 5: ADJUSTMENTS
Chain Adjustment
Table Adjustment
The chain drive in the Model G1033 transfers
movement from the hand wheel driven column to
the three other support columns. The chain drive
may require adjustment to remove slack as the
chain stretches over time, or as part of table leveling procedures. To adjust the chain:
The Model G1033’s table movement is critical to
the operation of the machine. As such, it is
essential that the table is aligned correctly with
the cutterhead and the head casting. For the
power feed to work correctly, it is important that
the table be the same distance from the head
casting in front and back. To make table adjustments, it will be necessary to construct the measurement block ''A''. See page 36 for a full size
print of block ''A''. To adjust the front-to-back distances:
1. Remove the two access panels on the
stand.
2. Loosen the two locking bolts and move the
idler sprocket until chain play has been
eliminated. See Figure 7.
3. Re-tighten the two locking bolts.
4. Check chain lubrication. Refer to the
Maintenance Section for further details.
1. Place Block ''A'' on the front right corner of
the table and raise the table until the top of
the block comes in contact with the bottom
of the head casting.
2. Without moving the table position, move
the block to the rear right corner under the
head casting. If the block will not fit under
the head casting, or if the gap between the
head casting and the table exceeds .016''
(use a feeler gauge to determine gap) you
will need to adjust the chain drive. See
Figure 8.
Idler Sprocket

G1033 20" Planer
Chain Drive
Adjust the chain drive by loosening the chain tensioner and loosen the chain until you can turn
each corner sprocket independently. If the back
of the table is too high, the back two sprockets
will need to be rotated clockwise to lower the
table. Each tooth on the sprocket represents
.016" of vertical movement as the cogs are
turned. Make sure, as you turn the sprocket, to
keep an accurate tooth count to ensure that the
table is lowered equally on both the left and right
sides. Turn the sprockets in small increments
until the front clearance matches the back.
When the front-to-back clearance is within the
.016'' tolerance, tighten the idler sprocket on the
chain drive and tighten the lock bolts.
With the front-to-back adjustments made, we can
concentrate on the alignment between the table
and cutterhead. To check table-to-cutterhead
alignment:
1. Place Block ''A'' on the table under the left
end of the cutterhead. Raise the table until
the block touches the bottom of the cutterhead. See Figure 9.
2. Slide the block across the table toward the
right side of the cutterhead.
Figure 9. Using block to align cutterhead.
When you get the tolerance to within the .016''
range, micro-adjust by loosening the Allen head
cap screws and lifting the table upward or downward until the table and cutterhead are in alignment. See Figure 10. This process may require
adjusting the columns on both the left and right
hand sides until you find the correct combination.
REMEMBER: When making adjustments, be
certain to tighten fasteners after each step to
ensure the accuracy of your tests. When adjusting the chain drive, keep in mind that if the chain
becomes too loose, it will fall off of all the sprockets. Returning it to its proper location can be frustrating.
3. If the block becomes too tightly wedged
between the table and the cutterhead, or if
there is a noticeable gap between the block
and the cutterhead, the table will need to be
adjusted.
4. If you find a substantial gap (larger than
.016''), follow the directions above for loosening the chain drive and turn the two right
sprockets (independently of the chain) until
the gap is eliminated. Turn the sprockets
counterclockwise from the bottom to raise
the table.
5. If the table is too high at the right side,
rotate the sprockets in the opposite direction.
G1033 20" Planer

-13-
Bed Rollers
After completing adjustments to the table, align
the bed rollers. The height of the bed rollers will
vary, depending on the type of material you
intend to plane. When planing rough stock, you
will need to set the rollers high to keep the lumber from dragging along the bed. Milled lumber
should be planed with the rollers set lower. To
adjust the rollers correctly:
3. To adjust the rollers, loosen the setscrews
at the left end of the rollers and, using an
Allen® wrench, raise or lower the rollers on
their eccentric shafts to reach your desired
height across the table. See Figure 12.
1. Lay a good quality straightedge across
both bed rollers, using a machinist's square
to keep the straightedge perpendicular to
the table.
2. Using a feeler gauge, measure the distance between the straightedge and the
table. The tolerance between the table and
the straightedge should be the same
across the table. The ideal tolerance
should be between 0'' and .015'', the larger
measurement for rougher stock. See
Figure 11. Be careful using the larger tolerance. Anytime the rollers are higher than
the table the potential exists for snipe, or
gouging near the end of the board
Figure 12. Roller height adjustment.
4. Once your roller heights are corrected, retighten the setscrews.
5. Spin the rollers and inspect for free movement.
Planer knives are dangerously sharp. Use
extreme caution when working near cutting
surfaces. Failure to exercise care while
working near knives could result in severe
injury.

G1033 20" Planer
Knife Inspection
Knife Adjustment
The G1033 20" Planer comes equipped with a 4knife cutterhead. The knives must be periodically
replaced or adjusted. Adjustments should be as
precise as possible with tolerances within ±.001''
to prolong the sharpness of the knife edges.
Improperly adjusted knives can unbalance the
cutterhead and shorten bearing life, as well as
produce substandard planing results. The knives
are set at the factory before shipping, but now is
a good time to double-check. To inspect and
adjust knife set:
The knives are locked into the cutterhead with
wedge type gibs and gib bolts. Springs under the
knives give an upward pressure to help in the setting process. To re-align the knives:
1. Remove the upper cover to expose the top
of the cutterhead.
2. Carefully turn the cutterhead (using the pulley) until the first knife is top dead center.
3. Using the knife adjusting jig, check the
knife height. The jig should sit solidly with
both feet on the cutterhead. See Figure 13.
If the knife is adjusted properly, the contact
point at the center of each adjuster should
just touch the tip of the knife. If the knife
does not make contact, or if the knife causes the adjuster’s legs to not seat on the cutterhead, the knives need to be adjusted.
1. Loosen the gib bolts until the knife is forced
upward by the springs. The gib bolts turn
clockwise to loosen and counterclockwise
to tighten (when facing the head of the
bolt). See Figure 14.
2. Place the adjusters on the cutterhead as
described above, so the feet are securely
planted on the cutterhead. Make sure the
adjuster extension rod is parallel to the cutterhead, so both ends of the knife receive
equal pressure from the adjuster.
3. The downward pressure provided by the
adjuster will set the knives at a uniform protrusion of approximately .070" above the
cutter. The knife height should vary no
more than .001" across the length of the
cutterhead.
4. Maintain a constant pressure on the
adjuster while re-tightening the gib bolts.
5. Repeat the same procedure on the remaining knives. As mentioned before, the standard adjuster is satisfactory for reasonably
accurate knife setting tasks.

Feed Roller Speed
Roller Adjustment
The infeed and outfeed rollers power the stock
through the planer. They keep boards flat and
provide smooth movement. The power feed features two feed rates - 16 FPM and 20 FPM. The
speed can be changed by moving the feed control knob when the machine is running. See
Figure 15. Moving the knob toward the machine
(Pos B) produces the 20 FPM feed speed, away
from the machine (Pos D) produces 16 FPM and
a center position (Pos C) places the gearbox in
neutral.
The infeed and outfeed rollers must be set at
.040" below the level of the cutting edge of the
knives. To set the height of the infeed and outfeed rollers:
NOTICE
The feed rate must be set before feeding
lumber into the planer. DO NOT attempt to
change speeds after the planing operation
has begun. Damage to the gearbox will
result.
1. Disconnect the planer from its power
source.
2. Make sure the knives are set correctly.
3. Remove the chain cover. Refer to the prerun check for removal instruction.
4. Loosen the cap screw that holds the static
chain tensioner and swing the tensioner out
of the way. See Figure 16.
Figure 16. Static chain tensioner adjustment.
Figure 15. Feed speed control.
5. Place Block ''A'' under the cutterhead with a
.040'' feeler gauge above it and raise the
table until the block reaches the cutterhead.
Center one of the knives at the bottom of
the cutterhead as you raise the table. Rock
the cutterhead backward and forward as
you raise the table and stop when the knife
just touches the feeler gauge. See Figure
17.
6. The table is now positioned correctly. Lock
the table in place.
-16-
7. Remove the feeler gauge and move the
block to the right end of the infeed drive
roller.
G1033 20" Planer
11. Follow the same procedure at the other
end of the infeed roller and on both sides
of the outfeed roller. Do not change the
table height yet, the next sections will
require the same settings.
A
12. Be sure to tighten the lock nut as soon as
you have adjusted each roller to its proper
height.
Spring Tension
Figure 17. Feeler measures roller adjustment.
8. Move the feed speed control knob to the
center neutral position.
9. Rotate the sprocket at the end of the
infeed roller. The teeth at the bottom of the
roller should contact the top of the block if
the roller is properly adjusted. If the roller
teeth will not clear the block, or if there is a
gap between the block and the infeed
roller, you will need to make adjustments.
10. If you need to adjust the roller up or down,
loosen the lock nut and turn the setscrew
to raise or lower the rollers. See Figure 18.
Roller spring tension must be adjusted so that
roller pressure is uniform. To adjust roller spring
tension:
1. Locate the four adjustment screws located
on the top of the planer. See Figure 19.
2. Adjust screws #1 - #3 so that they protrude
1
⁄8" above the head casting.
3. Adjust screw #4 so that it protrudes 5⁄16"
above the head casting.

Chipbreaker
Pressure Bar
The chipbreaker breaks chips/curls as they are
cut by the cutterhead and forces chips to eject
from the cutting area. Due to its functions within
the planer, the chipbreaker should be adjusted
carefully and checked frequently for movement.
To adjust the chipbreaker:
Like the chipbreaker, the pressure bar controls
lumber as it passes under the cutterhead. The
pressure bar keeps lumber from lifting after it has
been planed. If the pressure bar is incorrectly
positioned, a number of machining defects
(including snipe and board lines) can result. A
pressure bar set too low can also place excess
load on the planer’s motor. The pressure bar
should be adjusted along with the infeed and outfeed rollers. To adjust the pressure bar:
1. Disconnect planer from its power source
and remove the top cover. Note the location
of the setscrews and lock nuts. See Figure
20.
1. Disconnect the planer from its power supply.
2. Remove top cover. Note setscrew and lock
nut pictured in Figure 21. Loosen the lock
nuts.
Figure 20. Chipbreaker adjustment.
2. Place your test block under the middle of
the chipbreaker (the table should still be at
the same height as it was when you set the
infeed and outfeed rollers).
Figure 21. Pressure bar adjustment.
3. Loosen the lock nuts at both ends of the
chipbreaker and turn the setscrews to raise
or lower the chipbreaker as necessary. The
chipbreaker will move evenly, so it does not
matter which setscrew you turn. (You will
need to raise the second setscrew if the
chipbreaker needs to be lowered).
4. When the chipbreaker reaches its proper
height .040'' below the cutterhead height,
tighten the lock nut and adjust the other
setscrew and lock nut to match.
-18-
3. Place the gauge block under the center of
the pressure bar and adjust the setscrew
until the pressure bar makes slight contact
with the tip of the block. Like the chipbreaker, the pressure bar can be adjusted
with one setscrew. Make sure to adjust the
second setscrew to match the one you’ve
just adjusted.
4. Tighten the lock nut in place.
G1033 20" Planer
Chip Deflector
Static Chain Adjuster
The chip deflector keeps chips from falling onto
the outfeed roller. To adjust the deflector:
Once the rollers, chip breaker and pressure bar
are properly adjusted, you will need to reset the
static chain tensioner. Proper tensioner adjustment is crucial to your planer’s operation. Not
only will it have a direct effect on the quality of
your work, incorrect tension on the drive chain
may cause the rollers to jam, or cause the chain
to break. To adjust the static chain tensioner:
1. Disconnect the planer from its power
source and remove the planer’s dust cover.
2. Loosen the deflector’s mounting bolts. See
the parts diagram for location.
3. Make sure the deflector is beveled toward
the cutterhead. Move the deflector until the
edge is approximately 1⁄16'' from the tip of
the cutting knives. Rotate the cutterhead to
ensure clearance.
4. Re-tighten the mounting bolts and return
the top cover to the planer.
NOTICE
When using a dust collector, it may be necessary to increase the distance from the
cutterhead/knives to the deflector to aid in
chip removal.
1. Place the test block under the right side of
the outfeed roller. Make sure that the block
and the roller are in slight contact.
2. Note the height of the table on the metric
portion of the scale below the handwheel.
Crank the handwheel until the table moves
one millimeter towards the head casting.
The outfeed roller will have lifted .040''.
3. Rotate the static chain tensioner up until
the chain is tight. See Figure 22.
Figure 22. Chain tensioner adjustment.
4. Once the chain is tight, secure the screw
that holds it in place and lower the table
until you can remove the block.
5. When the tensioner is correctly adjusted,
replace the backing plate and the chain
drive cover.
G1033 20" Planer

Scale Adjustment
Anti-Kickback Fingers
The scale can be adjusted for accuracy. The
machine will need to be run to make proper
adjustments. Follow the directions on the following page for a test run before attempting to make
adjustments. Once you’ve successfully tested the
planer:
The Model G1033 provides an anti-kickback system as a safety feature. The anti-kickback fingers
hang from a rod suspended across the cutterhead casting. The anti-kickback fingers should be
inspected regularly. Check the fingers to ensure
that they swing freely and easily. See Figure 24.
Do not apply oil or other lubricants to the antikickback fingers. Oil or grease will attract dust,
restricting the free movement of the fingers.
1. Set the table to the approximate thickness
of your test lumber. Measure the lumber
with calipers to determine its exact thickness.
2. Move the table to 1⁄16'' under the thickness
of your lumber and feed your test board
through the planer.
3. Turn the handwheel one full rotation and
run the board through once more. Turn the
board over and repeat.
Proper operation of the anti-kickback fingers are essential for the safe operation of
this machine. Failure to ensure that they are
working properly could result in serious
operator injury.
4. Re-measure the board and compare your
results with the scale. If there is a discrepancy, loosen the Allen® head bolts and
adjust to match your findings. See Figure
23.

SECTION 6: Operations
Test Run
Operational Tips
Once the assembly is complete and the adjustments are done to your satisfaction, you are
ready to test the machine.
1. Inspect lumber for defects, warping, cupping,
twisting, and for foreign objects (nails, staples, imbedded gravel, etc,). If you have any
question about the quality of your lumber, do
not use it. Remember, wood stacked on a
concrete floor can have small pieces of stone
or concrete pressed into the wood.
Turn on the power supply at the main panel.
Press the START button. Make sure that your finger is poised on the STOP button, just in case
there is a problem. The planer should run
smoothly, with little or no vibration or rubbing
noises. Strange or unnatural noises should be
investigated and corrected before operating the
machine further.
2. Use the full width of the planer. Alternate
between the left, the right and the middle
when feeding lumber into the planer. Your
knives will remain sharp much longer.
3. Scrape all glue off of joined boards before
planing.
DO NOT attempt to investigate or adjust the
machine while it is running. Wait until the
machine is turned off, unplugged and all
working parts have come to a rest before
you do anything!
If noises occur that cannot be found by visual
inspection, feel free to contact our service department for help.
4. Plane ONLY natural wood fiber. No wood
composites.
5. Surface wood with the grain. NEVER feed
end-cut or end-grained lumber into your
planer.
6. Do not use boards with knots, splits, crossgrain or other obvious blemishes or defects.
They can damage the machine and pose the
possibility of operator injury.
7. Keep your work area clear.
Operating this equipment has the potential
for flying debris to cause eye injury.
Always wear safety glasses or goggles
when operating equipment. Everyday
glasses or reading glasses only have
impact resistant lenses, they are not safety
glasses. Be certain the safety glasses you
wear meet the appropriate standards of the
American National Standards Institute
(ANSI).
G1033 20" Planer
8. When making multiple passes through the
planer on long stock, use the stock return
rollers on the top of the machine to move the
material back to the infeed side of the
machine.
9. Avoid planing wood with a high water content. Wood with more than 20% moisture
content or wood exposed to rain or snow, will
plane poorly and cause excessive wear to
the knives and motor. Excess moisture can
also hasten rust and corrosion.
-21-
Wood Characteristics
The species of wood, as well as condition, will
affect planing ability. The harder the wood, the
more difficult it will be to plane. We’ve included
below, a list of wood characteristics you may
encounter when planing. The following descriptions of defects will give you some possible
answers to problems you may encounter while
planing different materials. Possible solutions follow the descriptions.
Chipped Grain - usually a result of cutting
against the grain, or planing wood with knots or
excessive amount of cross grain. Chipped grain
can also be caused by dull knives or misaligned
chipbreaker. Often, chipped grain can be avoided
by slowing down the feed rate and by taking shallow cuts. If those options do not work, inspect
your lumber and determine if its grain pattern is
causing the problem. If the wood does not show
substantial crossgrain, inspect your knives for
sharpness and inspect the chipbreaker for proper alignment. See the Adjustment Section.
Fuzzy Grain - Usually caused by surfacing lumber with too high a moisture content. Sometimes
fuzzy grain is a characteristic of some woods,
such as basswood. Fuzzy grain can also be
caused by dull knives or an incorrect grinding
bevel. Check with a moisture meter. If moisture is
greater than 20%, sticker the wood and allow to
dry. Otherwise, inspect knife condition.
Glossy Surface - Usually caused by dull knives
taking shallow cuts at a slow feed speed. Surface
gloss will usually be accompanied by overheating. Often, lumber will be scorched and eventually, damage to knives will occur. If knives are
sharp on inspection, increase feed speed and/or
cutting depth.
Snipe - Occurs when board ends have more
material removed than the rest of the board.
Usually caused when one or both of the bed
rollers are set too high. Can also be caused by
the chipbreaker or pressure bar being set too
high. However, small amount of snipe is
inevitable.
-22-
Snipe can be minimized by proper adjustment of
the planer’s components, but complete removal
of snipe is extremely unlikely. More likely, you will
be able to reduce it to a tolerance of .002". If
snipe under that level is a problem, consider
planing lumber longer than your intended work
length and cut off the excess after planing is completed.
Uneven Knife Marks - Uneven knife marks can
occur when the chipbreaker is set too high.
Inspect cutterhead bearings if re-adjustment of
the chipbreaker fails to remedy the situation.
Chatter Marks - Usually caused by incorrect
chipbreaker and pressure bar setting heights.
Chatter marks can also be caused by running a
narrow wood piece through the planer at either
the right or left end of the cutterhead. Chatter, like
uneven knife marks, will show in the form of a
''washboard'' look. Chatter marks are more likely
to be inconsistent in appearance than uneven
knife marks.
Wavy Surface - Caused by poor knife height
adjustment, wavy surface appears when one
knife is taking deeper cuts than the rest of the
knives. Remedy by re-setting the knives to a tolerance of ± .001".
Pitch & Glue Build-up - Glue and resin build-up
on the rollers and cutterhead will cause overheating by decreasing cutting sharpness while
increasing drag in the feed mechanism. The
result can include scorched lumber as well as
uneven knife marks and chatter.
Chip Marks - Occur when chips aren’t properly
expelled from the cutterhead. The knives catch
the chips and drag them across the lumber being
planed. Chips tend to be random and non-uniform (as compared to chipped grain). Can be
caused by exhaust blockage or too much room
between the cutterhead and chip deflector. Using
a dust collection system in combination with the
planer can help reduce chip marks. Inspect the
chip deflector and readjust (as described earlier
in the text).
G1033 20" Planer
SECTION 7: MAINTENANCE
General
Knife Sharpening
Make a habit of inspecting your planer each time
you use it. Check for the following conditions and
repair or replace when necessary.
Knife sharpness is one of the most important factors in getting good results with the planer. Knives
can be made to last a long time if care is taken in
checking the condition of the wood which is put
into the machine. The biggest problem will come
from wood with nails or other metal embedded.
This will nick or chip the knives and can require a
complete regrinding. Another wear factor is sand,
grit, or other dirt on the surface of the wood which
the knives have to cut through. At the speed the
cutterhead is rotating, these types of surface contamination can have a very abrasive effect.
1. Loose mounting bolts.
2. Worn switch.
3. Worn or damaged cords and plugs.
4. Damaged V-belts.
5. Any other condition that could hamper the
safe operation of this machine.
DO NOT make adjustments or attempt any
maintenance procedures while this machine
is running. Ensure that the switch is off,
power is disconnected and moving parts
have stopped before making any adjustments. Failure to follow this directive could
result in serious operator injury.
This planer has knives with a grind angle of 45˚
which is a configuration which should suit most
general planing needs. The optimal grind or bevel
angle is a compromise between effective cutting
(the smaller the angle the better the cutting
action) and edge life where the larger the angle
the more the edge is supported, thus the longer it
will last.
For the best results it is best to have planer
knives sharpened by a professional sharpening
service which has the grinding and measurement
equipment to assure that the knife cutting geometry is maintained at optimum levels. It is a procedure which requires some care and precision,
otherwise a set of blades can be easily ruined.
Knives should always be ground as a set so they
can be properly matched. Unequal material
removal can result in an unbalanced cutterhead
which can affect not only planing surface quality
but ultimately the life of the cutterhead bearings.
Please refer to Section 5 Adjustments - Knife
Adjustments for complete detail on the removal
and reinstallation of the planer knives.
G1033 20" Planer
-23-
Lubrication
The Model G1033 features factory-sealed bearings. A sealed bearing requires no lubrication
during its lifetime. Should a bearing fail, your
planer will probably develop a noticeable rumble,
which will increase when the machine is put
under load. If allowed to get worse, overheating
of the journal containing the bad bearing could
occur. If the bad bearing is not replaced, it will
eventually seize - possibly doing damage to other
parts of the machine. Bearings are standard
sizes and can be replaced through Grizzly.
Fill
Drain
Figure 25. Gear Box drain and fill plugs.
Proper lubrication of other components of the
Model G1033 are essential for long life and trouble-free operation. Below is a list of components
that require periodic lubrication. Schedules are
based on daily use. Adjust accordingly for your
level of use.
Columns/Lead Screws - The four columns
should be lubricated weekly with light oil.
Unfasten dust covers to gain access. The four
lead screws should be lubricated with general
purpose grease once a month.
Worm Gear - The worm gear should be inspected monthly and lubricated when needed.
Remove the worm gear box to inspect. See parts
diagram for location.
Drive Chain - The drive chain should be inspected and lubricated monthly. Check sprocket, chain
and cotter pin during inspection. Use a general
purpose grease. Some chains will have master
links instead of cotter pins.
Feed Rollers - Daily lubrication of feed rollers is
crucial to the operation of your planer. Lubricate
before start-up. Each end of each power feed
roller has an oiling port located on the top of the
head casting. See Figure 26. Apply a light oil,
making sure that the lubricant penetrates the
bearing.
Chain - The table height adjustment chain should
be inspected monthly and lubricated when needed. A good quality bicycle chain lubricant works
well for periodic lubrication.
Gear Box - Gear box oil should be drained after
the first 20 hours of operation. See Figure 25.
Replace with 80W-90W gear oil. Inspect levels
periodically and change yearly. Replace gear oil
more frequently under heavy use. Fill until oil
reaches the top of the filler plug port for correct oil
level.
Figure 26. Feed roller lubrication points.

G1033 20" Planer
Belt Tension
Belt Alignment
Inspect the belts daily for the first couple of
weeks you operate the planer. This is the time
that the majority of stretching will occur. Adjust
belt tension by lowering the motor down slightly.
See Figure 27. Establish a periodic schedule of
inspection. Check for wear, cracking, nicks, or
glazing. Replace belts immediately if you spot
any signs of deterioration. Always use three belts
when operating the Model G1033.
Proper belt alignment prevents premature belt
wear. See Figure 28. Use a straightedge on the
edge of the pulleys to judge alignment.
Figure 28. Pulley alignment procedure.
Should you find that the pulleys are out of alignment:
Figure 27. Adjustments for belt tension.
1. Loosen the belt tension to allow motor
movement.
2. Loosen the four (4) bolts that secure the
motor to the mounting plate just enough to
allow the motor to be repositioned.
3. Slide the motor as required to align the pulleys..
4. Re-tighten the motor mount bolts carefully
to assure that the tightening process does
not move the motor.
5. Re-tension the belt as shown in the previous column.
6. Replace the belt cover.
