•Check coolant daily. Insufficient or dirty coolant can cause a low cutting rate and
premature blade failure. Dirty coolant may cause bacteria growth that may cause skin
irritation.
•When cutting magnesium never use soluble oils or emulsions (oil-water mix) as waster
may start an accidental magnesium chip fire. Talk to your industrial coolant supplier for
specific recommendations.
•Pay attention to wiping dry surfaces where coolant accumulates but does not evaporate
quickly such as between the bed and vice of the machine. This is to prevent the
machined surfaces from corroding being that a water-soluble coolant is used.
•When the saw arm is opened the interlock switch will function to stop all blade
movement. Do not remove this switch for any reason and check it’s function frequently.

1) Line the holes in handle up with the holes on the side of the stand like in the exploded
parts view.
2) Put the hex head screw with a washer through the handle and the stand.
3) On the back side, place another washer on the screw tighten before putting the hex nut
on.
4) Tighten the nut just enough to get it onto the screw.
5) Do this for all 4 holes before tightening all 4 hex nuts.
BLADE SELECTION
An 8-tooth per inch general use blade comes installed with this metal cutting bandsaw.
Additional blades in 4, 6, 8, and 10 tooth pitches are available. However, 3 teeth should be
engaged with the workpiece at all times for proper cutting.
For maximum cutting efficiency and lowest cost per cut, it is important to select the blade with
the correct number of teeth per inch (TPI) for the material being cut. The material size and
shape dictate tooth selection.
Located on the saw is a chart to determine the tooth pitch or TPI needed for cutting various
material types and shapes.
For piping, tubing, and structural the material thickness used is the average thickness that the
blade goes through during the cut.

BLADE SPEED
Band speed recommendations presented on this chart are approximations and are to be used
as a starting point for most applications. For exact sawing parameters consult your blade
supplier. 120V outlets use 60 Hz columns.

COOLANT
Use a water-soluble coolant.
Coolant is mixed 10:1, 10 parts water to one-part coolant. Once the coolant is mixed pour it into
the tray and let it run down into the reservoir. If a lot of coolant pools on one side of the tray the
saw may need to be leveled to let all the coolant drain from the tray equally and ensure all of the
coolant in the system is cycled when cutting.
OPERATION
VICE
Turning the handwheel (item 364) at the end of the bed will move the front jaw of the vice
forward and back. To tighten down a work piece insert it between the jaws and use the
handwheel to tighten the vice around the workpiece. Then lock the pressure knob of the vice by
pulling the handle (item 373 & 374) down into the locked position.

Vice adjustment for angled cuts:
Loosen the 3 hex head screws and the nut attached to the carriage bolt. Once loosened this will
allow both vice jaws rotate up to 45°. The carriage bolt may need to be loosened more to get to
bigger angles. Once each jaw is set to the same angle tighten all fasteners to secure vice in
place.
WORK STOP ADJUSTMENT
1) Loosen the thumb screw (item 48) holding the work stop casing (item 51) to the shaft.
2) Adjust the work stop casting to the desired length.
3) Rotate the work stop as close to the bottom of the cut as possible.
4) Tighten thumbscrew.

CHANGING FEED RATE
Located on the front right of the saw is the adjustment for the feed rate as well as the down feed
lock. To slow the feed rate, turn the knob clockwise, counterclockwise causes the feed to
increase. Feed can be adjusted 0-10, 0 being no feed pressure causing the saw to fall the
fastest. At 10 the highest feed pressure, causing the saw to fall the slowest at this setting.
To lock the saw head in an elevated position, turn the handle so that it is perpendicular with the
feed cylinder. To unlock and resume down feed, turn the handle back parallel with the cylinder.
See figure below.
OPERATING
1) Raise saw head to partial vertical position and use the down feed lock to lock the head.
2) Open vice and insert the workpiece. Close vice securely around the workpiece.
a. If work piece is significantly long, support the end of the workpiece.
3) Lower the head of the saw until the blade is within a half an inch from the workpiece.
a. Starting the saw while it’s already running could damage the blade.
4) Set the down feed rate for the type of material that is being cut.
5) Turn the saw on and press the start button. Once the saw is up to full speed release the
head stop to let the saw gravity feed down into the workpiece.
a. Never force the saw into the work this could damage the saw as well as the work.
6) Once the saw has made the cut entirely, stop the saw or let the saw hit the limit switch.
7) Lift the head of the saw and loosen the vice to remove the workpiece.

13 REV012019
CHANGING BLADE SPEED
Before changing the blade speed ensure that the saw is properly disconnected from its
power source
1) Loosen, but do not remove, the two 5/16” hex head screws under the motor pulley cover.
This allows the pulley to move slightly to readjust the belt for blade speed. Shown below.
2) Remove the motor pully cover and unclip the plastic fastener to open.
3) Using the “BLADE SPEEDS” section in the manual determine what blade speed is ideal
for the material being cut.
4) Using the chart on the inside of the cover determine what position to move the belt to get
the desired blade speed.
a. For standard 120V outlet use the 60Hz column.
b. Pulley orientation in illustration may differ slightly from actual saw. If chart displays
the belt in the top groves of the pulleys for a speed, then put the belt in the top
grooves, no matter the orientation of the pulleys.
5) After getting the belt in place, slide the motor left until the belt is taught, then tighten the
hex head screws securing the motor in place. Then close the pulley motor cover.

1) Raise saw head to its highest position and open the back blade cover by unscrewing the
two knobs on the back side of the blade guard (item 332).
2) Loosen the blade tensions knob (counter-clockwise) enough to allow the blade to slip off
the pulleys.
a. Set the old blade aside to dispose of.
3) Place new blade between the guide bearings.
a. Make sure the teeth are slanting towards the motor when installed.
4) Slip the blade around the motor pulley and hold in position.
5) Pull the blade taught around the motor pulley and pull the other end up towards the top
pulley.
6) Carefully slip the other end of the blade over the top pulley.
7) Tighten the tension knob (clockwise) until the blade is just tight enough to not slip.
a. Using a gloved hand pull along the blade’s length to make sure the blade does not
slip.
b. Be careful not to overtighten the blade.
8) Replace the blade guards.
9) Place 2-3 drops of oil on the blade.

BLADE GUIDE BEARING ADJUSTMENT
Before adjusting the blade guide bearings ensure that the saw is properly disconnected from
its power source.
Guide bearing position is extremely important in order get a straight, proper cut. The need for
adjustment should rarely occur if the saw is being used properly. If the guides get out of
adjustment is important to readjust immediately to avoid blade damage and waste of materials.
Because guide adjustment is a critical factor in performance of your saw it is best to a new blade
in to see if it will correct the poor cutting before beginning to adjust the guides. The guides
should have .000” (just touching) to .001” of clearance between themselves and the blade.
1) The outer bearing is mounted to an eccentric bushing and can be adjusted.
a. The inner bearing is fixed and cannot be adjusted.
2) While holding the bolt with a hex wrench loosen the nut on the outside.
3) Position the eccentric by turning the bolt to the desired position of clearance.
4) Tighten the nut.
5) Adjust the second blade guide in the same manner.
LUBRICATION
•6-8 drops of SAE-30 oil on driven pulley bearing once a week.
•Vise lead screw as needed.
•Drive gears run in an oil bath and does not require a lubricant change more than once a
year unless the oil gets contaminated or a leak occurs. Use 80/90 synthetic gear oil.
