WARNING
Read this manual completely and observe all warning labels on the machine. Oliver Machinery has made
every attempt to provide a safe, reliable, easy-to-use piece of machinery. Safety, however, is ultimately
the responsibility of the individual machine operator. As with any piece of machinery, the operator must
exercise caution, patience, and common sense to safely run the machine. Before operating this product,
become familiar with the safety rules in the following sections.
Always keep guards in place and in proper operating condition.
Keep hands out of line with the saw blade.
Use a push stick.
1. If you are not properly trained in the use of a bandsaw do not use until the proper training has been
obtained.
2. Read, understand and follow the safety instructions found in this manual. Know the limitations and
hazards associated with this machine.
3. Electrical grounding: Make certain that the machine frame is electrically grounded and that a
ground lead is included in the incoming electrical service. In cases where a cord and plug are used,
make certain that the grounding plug connects to a suitable ground. Follow the grounding procedure
indicated in the National Electrical Code.
4. Eye safety: Wear an approved safety shield, goggles, or glasses to protect eyes. Common
eyeglasses are only impact-resistant, they are not safety glasses.
5. Personal protection: Before operating the machine, remove tie, rings, watch and other jewelry and
roll up sleeves above the elbows. Remove all loose outer clothing and confine long hair. Protective
type footwear should be used. Where the noise exceeds the level of exposure allowed in Section
1910.95 of the OSHA Regulations, use hearing protective devices. Do not wear gloves.
6. Guards: Keep the machine guards in place for every operation for which they can be used. If any
guards are removed for maintenance, DO NOT OPERATE the machine until the guards are
reinstalled.
7. Work area: Keep the floor around the machine clean and free of scrap material, saw dust, oil and
other liquids to minimize the danger of tripping or slipping. Be sure the table is free of all scrap,
foreign material and tools before starting to use the machine. Make certain the work area is well
lighted and that a proper exhaust system is used to minimize dust. Use anti-skid floor strips on the
floor area where the operator normally stands and mark off machine work area. Provide adequate
work space around the machine.
8. Material condition: Do not attempt to saw boards with loose knots or with nails or other foreign
material. Do not attempt to saw twisted, warped, bowed stock.
9. Operator position: Maintain a balanced stance and keep your body under control at all times.
10. Before starting: Before turning on machine, remove all extra equipment such as keys, wrenches,
scraps, and cleaning rags away from the machine.
11. Careless acts: Give the work you are doing your undivided attention. Looking around, carrying on a
conversation, and “horseplay” are careless acts that can result in serious injury.
4
12. Disconnect all power sources: Before performing any service, maintenance, adjustments or when
changing blades. A machine under repair should be RED TAGGED to show it should not be used
until the maintenance is complete.
13. Job completion: If the operator leaves the machine area for any reason, the bandsaw should be
turned "off" and the blade should come to a complete stop before their departure.
14. Replacement parts: Use only genuine Oliver Machinery factory authorized replacement parts and
accessories; otherwise the warranty and guarantee is null and void.
15. Misuse: Do not use this Oliver bandsaw for other than its intended use. If used for other purposes,
Oliver disclaims any real or implied warranty and holds itself harmless for any injury or damage which
may result from that use.
16. Drugs, alcohol and medication: Do not operate this machine while under the influence of drugs,
alcohol, or any medication.
17. This machine is deigned for cutting wood products only. Do not use to cut any kind of metal or
substance other then wood.
18. Never start the saw while a workpiece is in contact with the blade.
19. Make sure the blade is running in the proper direction. The teeth should be pointing down at the
point the blade enters the table viewing from the front of the saw.
20. Health hazards: Some dust created by power sanding, sawing, grinding, drilling and other
construction activities contains chemicals known to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
Lead from lead-based paint.
Crystalline silica from bricks and cement and other masonry products.
Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce
your exposure to these chemicals, work in a well-ventilated area, and work with approved safety
equipment, such as those dust masks that are specifically designed to filter out microscopic particles.
Familiarize yourself with the following safety notices used in this manual:
CAUTION: (This means that if precautions are not heeded, it may result in minor or moderate injury
and/or possible machine damage)
WARNING: (This means that if precautions are not heeded, it could result in serious injury or possibly
even death).

Uncrating the Machine
Your bandsaw should arrive crated as shown in
Picture 1. Inspect the unit for signs of shipping
damage. If damage is found, contact the
delivering freight carrier immediately. Retain all
packaging materials in case it becomes
necessary to ship the machine back to the
dealer or to another site.
Machine Preparation and Setup
WARNING
The equipment used to lift this machine must
have a rated capacity at, or above the weight
of the bandsaw. Failure to comply may
cause serious injury!
The bandsaw is bolted to the skid with four bolts.
Remove the bolts. Screw the eyebolts (#10,
Picture 2) into the top of the machine and use a
forklift or similar to lift the bandsaw off the skid
and into position. The bandsaw must be
positioned on a smooth, level surface. The area
must be well lit and have plenty of room to
maneuver with large pieces of wood.
Level the saw front to back and side to side
using a level placed on the table. Use shims
under the corners, if necessary, but make sure
the saw is stable before being placed into
service.
Clean all rust protected surfaces with a
commercial solvent. Do not use acetone,
gasoline, lacquer thinner or any type of
flammable solvent, or a cleaner that may
damage paint. Cover cleaned surfaces with
WD-40 or a 20W machine oil.

Fence Assembly
1. Disconnect machine from power source.
2. Install rail brackets (A, Figure 1) to the table
as shown using the supplied hardware. See
inset B and notice the elongated hole of the
bracket mates with the edge of the table Do
not fully tighten at this time.
Figure 1
3. Loosely install the supplied carriage bolts
and nuts onto the rail brackets as shown in
inset B of Figure 2. Line up the two large
holes in the rail with the two carriage bolt, as
shown in Figure 2. Slide the rail to the right
and tighten into place.
Figure 2
4. Place the fence on the rail as shown in
Figure 3. Use the slotted holes in the rail
brackets to raise or lower the front end of
the fence so it closely matches the height of
the rear end of the fence. Tighten into
place.
Figure 3
5. To fix the measuring tape to the rail, move
the fence into position so that it is just
touching the blade as seen in Figure 3.
Note that the fence has two position
indicators. Cut the tape in the middle
between the two zero’s.
6. The measuring tape is peel and stick but at
this time just slide the left tape under the
fence bracket on the rail so the zero mark on
the tape lines up with the left indicator on the
fence as shown in Figure 4.
Figure 4
7. Mark the position of the tape on the rail. As
well, make sure the tape is centered
between the V’s of the fence to prevent the
fence rubbing on the tape.
8. Remove the backing and fix the tape to the
rail.
9. Repeat for the right side.

Installing Blade
WARNING
Bandsaw blades are sharp so be very careful
while handling. Failure to comply may cause
serious injury!
1. Disconnect machine from power source.
2. Open upper and lower doors.
3. Remove fence and fence rail.
4. Remove table pin (A, Figure 5).
5. Put on leather gloves to protect your hands
from the sharp teeth of blade.
6. Slide blade through table slot, ensuring that
the teeth are pointing down toward the table.
7. Center the blade (B, Figure 5) on both the
upper and lower wheels. Carefully thread
the blade through the upper and lower blade
guides (C & D) as shown in Figure 5. Note:
It may help to move the upper wheel down.
This can be accomplished by rotating the
handwheel (E, Figure 5).
Tensioning Blade
Proper blade tension is essential to any cutting
operation on a bandsaw. Too little, or too much
blade tension can cause blade breakage and/or
poor cutting performance. Tension will very
depending the blade being used and the type of
material being cut.
1. Disconnect machine from power source.
2. At this point the blade should be properly
positioned, but slack. Increase tension on
the blade by rotating tensioning handwheel
(E, Figure 5).
3. Move the upper guide assembly (C, Figure
5) and lower guide assembly (D, Figure 5) if
they interfere with the blade during
tensioning.
4. A reference gauge (Figure 6) indicates the
approximate tension setting for the width of
blade being used. Turn the tensioning
handwheel until the indicator falls on the
appropriate mark. Keep in mind that blades
will last longer if you release tension when
not in use. Also, new blades will often
stretch with use, and not all blades will be
exactly the same length.
5. When not using the saw, release the blade
tension to minimize over-stretching.
Figure 5

Blade Tracking
Blade tracking has been adjusted at the factory
and shouldn’t need any adjustment. If you are
experiencing a problem follow the below listed
steps.
Disconnect machine from power source.
1. Blade must be properly tensioned before
adjusting blade tracking, see “Tensioning
Blade” page 8. Move the upper guide
assembly and lower guide assembly if they
interfere with the blade.
2. Open upper wheel door and rotate the wheel
forward by hand. Observe position of the
blade on the wheel. The blade should rest
in approximately the center of the wheel.
3. If adjustment is necessary, loosen the hex
nut (A, Figure 7) on the rear of the machine
near the tension indicator.
4. Adjust tracking by turning the knob (B,
Figure 7) in 1/4 turn increments. Rotate
wheel forward, and observe the position of
blade on the wheel. Rotating the knob
counter-clockwise will move the blade
towards the front of the wheel. Rotating the
knob clockwise will move the blade towards
the back of the wheel.
5. Continue with adjustments until the blade is
tracking properly.
6. Tighten the hex nut (A, Figure 7) while
holding knob (B, Figure 7).
Figure 7
Adjusting The Upper Blade Guide
Disconnect machine from power source.
Note: There are three adjustments
necessary to correctly set the blade
guides. Please completely read through
the following three adjustments entirely
before attempting to set the guides
because the position of the blade may
require you to perform Adjustment 3
before Adjustment 2.
Adjustment 1
1. Blade tension and tracking must be properly
adjusted prior to blade guide setup, see
“Tensioning Blade” page 8 and “Blade
Tracking” page 9.
2. To set the blades, fold a piece of paper
around the back of the saw blade and slide it
up between the blade guides as shown in
Figure 8.
3. Loosen allen bolts (A, Figure 8) and position
the guide bracket so that guides ‘B’ and ‘C’
are just touching the paper and not pushing
the blade aside. If your hand is large
enough, you could reach around the back of
both bracket and squeeze them both
together at the same time. Then lock into
place with allen bolts ‘A’.
Note: For best results the upper blade
guide should be lowered so that it is just
above the workpiece while cutting (see
Figure 9). Loosen lock ‘B’ and use wheel ‘A’
to adjust the guide up or down. Lock into
place once set.

Adjusting the Blade Guides (cont.)
Adjustment 2
1. Blade guides ‘B’ and ‘C’ of Figure 8 need to
be positioned to just behind the blade gullet as
shown by ‘D’ of Figure 9.
2. To do this, loosen the allen bolt (B, Figure 9)
then slide the entire bracket assembly to the
correct position. Then tighten back the allen bolt
‘B’.
Figure 9
Adjustment 3
1. The rear blade support bearing (E, Figure 8)
should be positioned so that it is just barely
touching the back of the blade.
2. To do this, loosen the thumb screw (C, Figure
9) then turn the knurled knob (A, Figure 9) to
adjust the rear blade support bearing.
Adjusting the Lower Blade Guide
The lower blade guide adjusts in the same way
as the upper however Adjustment 2 is achieved
by loosening the set screw (Figure 10).
The rear blade support bearing Adjustment 3 is
accessed by removing the panel shown in
Figure 10.

Squaring Table to the Blade
1. Disconnect machine from power source.
2. Blade tension, tracking and guide setup
must be properly adjusted prior to squaring
the table to the blade, see “Tensioning
Blade” page 8, “Blade Tracking” page 9,
“Adjusting Upper Blade Guides” page 9 and
“Adjusting Lower Blade Guides” page 10.
3. Place a square (A, Figure 11) on the table
against the blade to see if the table is 90
degrees to the blade.
4. If adjustment is necessary loosen lever (B,
Figure 11) and tale stabilizing knob (B,
Figure11) and tilt table until it is square to
the blade. Re-tighten the lever and knob.
5. Adjust pointer (D, Figure 11) to read zero.
6. Check to see that the table is still square to
blade and make any additional adjustments.
