IMPORTANT SAFETY INSTRUCTIONS
Warnings
1. Read and understand the entire owner’s manual before attempting assembly or operation.
2. Read and understand the warnings posted on the machine and in this manual. Failure to comply
with all of these warnings may cause serious injury.
3. Replace the warning labels if they become obscured or removed.
4. This band saw is designed and intended for use by properly trained and experienced personnel
only. If you are not familiar with the proper and safe operation of a band saw, do not use until
proper training and knowledge have been obtained.
5. Do not use this band saw for other than its intended use. If used for other purposes, JET
disclaims any real or implied warranty and holds itself harmless from any injury that may result
from that use.
6. Always wear approved safety glasses/face shields while using this band saw. Everyday
eyeglasses only have impact resistant lenses; they are not safety glasses.
7. Before operating this band saw, remove tie, rings, watches and other jewelry, and roll sleeves up
past the elbows. Remove all loose clothing and confine long hair. Non-slip footwear or anti-skid
floor strips are recommended. Do not wear gloves.
8. Always use the blade guard on all ''through-sawing'' operations. A through-sawing operation is
one in which the blade cuts completely through the workpiece.
9. Some dust created by power sanding, sawing, grinding, drilling and other construction activities
contain 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, cement and other masonry products.
•Arsenic and chromium from chemically treated lumber.
Your risk of exposure 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 face or dust masks that are specifically designed to filter out microscopic
particles.
10. Do not operate this machine while tired or under the influence of drugs, alcohol or any
medication.
11. Make certain the switch is in the OFF position before connecting the machine to the power
supply.
12. Make certain the machine is properly grounded.
13. Make all machine adjustments or maintenance with the machine unplugged from the power
source.
14. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting
wrenches are removed from the machine before turning it on.
15. Keep safety guards in place at all times when the machine is in use. If removed for maintenance
purposes, use extreme caution and replace the guards immediately.
16. Make sure the band saw is firmly secured to the stand (or bench) before use.
17. Check damaged parts. Before further use of the machine, a guard or other part that is damaged
should be carefully checked to determine that it will operate properly and perform its intended
function. Check for alignment of moving parts, binding of moving parts, breakage of parts,
mounting and any other conditions that may affect its operation. A guard or other part that is
damaged should be properly repaired or replaced.

19. Provide for adequate space surrounding work area and non-glare, overhead lighting.
20. Keep the floor around the machine clean and free of scrap material, oil and grease.
21. Keep visitors a safe distance from the work area. Keep children away.
22. Make your workshop child proof with padlocks, master switches or by removing starter keys.
23. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play”
are careless acts that can result in serious injury.
24. Maintain a balanced stance at all times so that you do not fall into the blade or other moving
parts. Do not overreach or use excessive force to perform any machine operation.
25. Use the right tool at the correct speed and feed rate. Do not force a tool or attachment to do a
job for which it was not designed. The right tool will do the job better and safer.
26. Use recommended accessories; improper accessories may be hazardous.
27. Maintain tools with care. Keep saw blades sharp and clean for the best and safest performance.
Follow instructions for lubricating and changing accessories.
28. Make sure the work piece is held firmly against the rip fence or miter gauge as it is fed through
the blade.
29. Turn off the machine before cleaning. Use a brush or compressed air to remove chips or debris
—do not use your hands.
30. Do not stand on the machine. Serious injury could occur if the machine tips over.
31. Never leave the machine running unattended. Turn the power off and do not leave the machine
until it comes to a complete stop.
32. Remove loose items and unnecessary work pieces from the area before starting the machine.

caution when lifting! Stabilize until firmly
attached to the stand! Failure to comply may
cause serious injury!
Referring to Figure 5:
1. With the aid of a second person, lift the saw
body and place onto the stand top. Be sure
front of bandsaw body (with JET logo) faces
stand front and align the mounting holes.
2. Secure the bandsaw assembly to the stand with
4ea M8x35 hex cap screws, 8ea M8 flat
washers, 4ea M8 lock washers, and 4ea M8
hex nuts.

Mounting the Table onto Bandsaw
1. Attach trunnion support bracket to saw body
with the two M8 x 30 hex cap screws and two
M8 lock washers. (see Figure 6).
2. Thread the M8 hex nut onto the table stop bolt
(M8 x 80), then thread the bolt into the trunnion
so that approximately 2" protrudes above the
trunnion (see Figure 7).
3. To mount the table, remove the table pin and
table insert from the center opening.
(see Figure 8).
4. Orient the table so that the saw blade will pass
through the slot in the table and into the center
opening. Continue holding up the table, and
turn the table so the two screws that are
hanging vertically from below the table can slide
into the holes on the trunnion support bracket.
Lower the table. The screws should now
protrude below the trunnion support bracket.
Mount the machine table to the trunnions and
attach the lock knobs (A, Fig 9).
Set the table to be square to the sawblade and
reference the table stop (B) and the tilting scale
(D).
5. Reinsert the table insert and table pin.

Note:Once table is mounted to the trunnion bracket
(see section below) and the blade is mounted in the
saw (see section “Changing Blades”) you may
choose to fine tune the blade parallel to the miter
slot. Using a square positioned in the miter slot,
loosen screws shown in (B, Figure 9) and lightly tap
the table into position so the blade is parallel with
the miter slot. Then gently tighten down the
screws. This adjustment will ensure square cuts
when using a miter gauge.
This adjustment will NOT correct drift of a blade
when ripping with a rip fence.
Mounting the Fence assembly to
Bandsaw
1. Attach the front fence guide rail to the table with
2ea M6x20 hex cap screws, 2ea M6 lock
washers, and 2ea M6 flat washers.
2. Attach the rear fence guide rail to the table with
the 2ea black M6x16 hex cap screws
(Refer to figure 10)
3. Thread 1ea M8 hex nut onto the fence lock
handle, then thread the handle into the fence
and secure it in place by tightening the hex nut
against the fence. Move the fence lock handle
up, position the fence face between the column
and the blade, as shown in Figure 20, then
place it onto the front fence rail. (Refer to Figure
11)
4. Place the fence assembly (Figure 11) on the
guide rail and align the fence profile to be
parallel to the mitre groove in the table.
5. Thread the M6 hex nut onto the fence stand-off,
then thread it into the rear under side of the
fence profile. Check the clearance between the
table and the fence. The gap should be appr.
1mm. Use the support rails and the rear glide
piece to adjust.

Adjustments
Unplug the machine from the
power source before making any repairs or
adjustments. Failure to comply may cause
serious injury.
Tilting the Table
1. Loosen the front and rear lock knobs
(Figure 13).
2. Tilt table up to 45 degrees to the right or up to
10 degrees to the left. The angle can be read
on the scale mounted to the trunnion.
3. Tighten two lock knobs (Figure 14).
Note: Table stop (Figure 13) must be adjusted
downward to allow the table tilt to the left.
Adjusting 90

Table Stop
1. Disconnect machine from power source.
2. Loosen lock knobs (Figure 13) and tilt table left
until it rests against the table stop.
3. Use a square placed on the table and against
the blade (Figure 14) to see if the table is 90
degrees to the blade.
4. If an adjustment is necessary, loosen lock
knobs, tilt table to the right, and lock in place.
5. Loosen jam nut and turn table stop (Figure 13)
left or right to raise or lower the stop. Tighten
jam nut to hold table stop in place.
6. Unlock table, tilt back onto table rest and
confirm table is 90 degrees with the blade.
7. If necessary, adjust scale pointer to zero.

Changing Blades
1. Disconnect machine from power source.
2. Loosen blade tension by pushing up on the
release lever (Figure 15).
3. Remove the table insert and the table pin.
4. Open both wheel covers.
5. Back off the Thrust Bearing and both the upper
and lower guide bearings from the blade.
6. Remove the blade from between upper and lower
blade guides. Remove blade from upper and lower
wheels. Turn blade to direct through slot in table.
7. Before mounting blade make sure the orientation
of the blade is so the teeth are pointing down. If
holding blade in front of you, as if mounted in the
saw, the teeth should point down on right side of
the loop. If not the blade is inside out. Twist the
blade right side in to correct this, wear heavy gloves
when doing so.
8. Guide new blade through table slot. Place blade
in upper and lower blade guides.
9. Place blade in the middle of the upper and lower
wheel.
10. Replace table insert and table pin.
Figure 15

Adjusting Blade Tension
1. Disconnect machine from power source.
2. Make sure the blade is tensioned with the
release lever in the down position (Figure16).
3. Turn blade tension knob (Fig.15) clockwise to
tension blade. The blade width gauge (D,
Fig.17) indicates the approximate tension
according to the width of the blade. Initially, set
the blade tension to correspond to blade width*.
4. As you become familiar with the saw, you may
find it necessary to change the blade tension
from the initial setting. Changes in blade width
and the type of material being cut will have an
effect on blade tension.
5. Keep in mind that too little or too much blade
tension can cause blade breakage.
6. If the blade will not tension correctly once the
blade tensioner and tension knob are properly
set then you may need to adjust the blade
tensioning device.
7. Using a 2.5mm hex wrench loosen the set screw
(B, Fig.17) in the lower bushing (C, Fig. 17).
8. Using a pair of pliers rotate the bushing (C, Fig.
17) down only about 1 to 2 turns.
9. Replace the set screw (B, Fig. 17) and check for
proper tension. Repeat the process if necessary.
*Note: When changing blades from a wider blade
to a narrower blade that you should adjust the blade
tension down to the appropriate width of the new
blade. (use blade width gauge) BEFORE
disengaging (up position) the blade release lever.
Now you may proceed with the standard method of
blade changing
Failure to do so will result in over-tensioning the
blade and possible blade breakage or even
personal injury.
Figure 16
Figure 17
Adjusting Blade Tracking
Disconnect machine from the
power source! Never adjust blade tracking with the
machine running!
Failure to comply may cause serious injury!
1. The blade must be properly tensioned before
adjusting blade tracking. The release lever
should be in the down (tensioned) position.
Make sure blade guides and blade bearings do
not interfere with the blade.
2. Open top blade cover. Rotate the wheel forward
and observe the position of the blade on the
wheel - it should be in the center of the wheel.
3. If adjustment is necessary, loosen wing nut
(Figure 16), and tighten tracking knob slightly to
move blade toward rear of machine. Slightly
loosening the tracking knob will cause the blade
to track toward the front of the machine.
4. Tighten wing nut after blade is tracking in the
center of the wheel.
Figure 18
“Tracking” refers to how the blade is situated upon
the wheels while in motion. The saw blade should
be on the centre of the rubber tyres
