electrician. All adjustments or repairs must
be done with the machine di sconnect ed from
the power source, unplugged. Failure to
comply may result in serious injury!
The Model J-9225 bandsaw is rated at 230V.
This machi ne is not supplied with a pl ug. Use a
plug and outlet rated at least 20amps. The
circuit for the machi ne should also be protec ted
by at least a 20 amp circuit break er or fuse.
Make sure that the blade moves in the
correct direct ion. If it does not, simply rev erse
two of the phase wires on the supply input.
The sawing machi ne is now ready for use.

Controls and Indicators
Control Panel
The operating controls for the bandsaw are
located on the control panel (Figure 4) and
consist of the f ollowing c ontrols and indicat or s:
Emergency Stop Switch – by depressing this
switch the user can quickly stop the machine
when it is in operati on; to restart, turn cl ockwise
slightly to release then press Start switch
Feed Rate Control – used i n c onjunction with t he
Feed Rate Start/Stop Control (see below); this
knob is used to set the downward head speed
that is appl ied t o the saw blade. T he f eed rat e i s
proportional to the opening of the valve. When
set to zero, t he saw head is l ocked in position.
Increasing the v alve opening (count er-clockwise
adjustment ) increases the f eed rate; decreasing
the valve opening (clockwise adjustment)
reduces the feed r ate.
Feed Rate Start/Stop Control – used in
conjunction with the Feed Rate Control (see
above); in the locked position the saw head is
prevented from descending; in the unlocked
position the saw head will descend at the rate
determined by the F eed Rate Cont r ol setting.
Motor Speed Selector – select Low for 137
SFPM, High for 275 SFPM; machine will not
operate when Off is selecte d .
On/Off Switch – main power switch
Standby Lamp Indicator – indicates that power is
present, i. e., machine is plugged i n and On/Off
Switch in set to ON.
Start Switch – press to start machine, also: set
On/Off Switch to ON, select Motor Speed
Selector t o Low or High, Em ergency Stop must
be released.
Blade Speeds
The Model J-9225 bandsaw has two blade
speeds which are set by the Motor Speed Selector dial (D, Fi g. 4). I n normal oper ation the
machine is stopped, the speed selected
(Low/High) then restarted. Changing the speed
while in operat ion will shut the machine off and
will requir e r estar ting (E, Fig. 4).
Figure 4

Blade Selection
Operations
The bandsaw is deliv ered with a saw blade that
is adequate for a variety of cut-off jobs on a
variety of common material s. A general -purpose
blade is provided as standard equipment with
the machine. After-market blades can be
acquired for specif ic c utti ng jobs.
A coarse blade could be used for a solid steel
bar, but a finer toot h blade would be used on a
thin-wall steel tube. In general , the bl ade choice
is determined by the thickness of the material;
the thinner the materials; the finer the tooth
pitch.
A minimum of three teeth should be on the
workpiece at all times for proper cutting. The
blade and workpiece can be damaged if the
teeth are so far apart that they straddle the
workpiece.
For very high production on cutting of special
materials, or to cut hard-to-cut materials such as
stainless steel, tool steel, or titanium, call JET
for more specific blade recommendations. JET
can provide you with very specific instructions
regarding the be st blade (and c oolant or cutt ing
fluid, if needed) for the material or shape
supplied.
Hydraulic Feed Control
The weight of the saw head provides the force
needed to cut thr ough the workpiece. The cut-off
saw has a hydraulic cylinder that controls the
feed rate of the saw.
The hydraulic feed control circuit consists of a
single acting hydraulic cylinder and a feed rate control. T he feed control cylinder r esists motion
in the downward direction to control the feed
rate. The control cylinder offers no resistance
when raised upward.
The feed rate controlknob (Figure 4) controls
the rate at whic h the saw head is lowered. The
control knob (needle valve) controls the rate at
which the hydraulic fluid is released from the
hydraulic cylinder. When the needle valve is
closed, the cylinder is locked. With the needle
valve sli ghtly open, t he cyli nder permit s slow, or
light, downward f orce. Opening t he needl e v alv e
further incr eases the feed rate.
The needle valve is adjusted until the saw is
operating eff iciently. The effici ency of operation
is usuall y ev aluated by observing c hip formation.
Blade efficiency is further described below.
Blade Break-in Procedures
New blades are v ery sharp a nd, theref ore, have
a tooth geometry that is easily damaged if a
careful break-in procedure is not followed.
Consult the blade manufacturer’s literature for
break-in of specifi c blades on specific materi als.
However, the following procedure will be
adequate for br eak-i n of J ET-suppli ed bl ades on
lower alloy ferrous materials.
1. Clamp a section of round stock in t he vise.
The stock should be 2 inches or larger in
diameter.
2. Operate the saw at low speed. S tart the cut
with a very light feed rate.
3. W hen t he saw has com pl eted 1/ 3 of the c ut,
increase the f eed rate slight ly and allow the
saw to complete the cut.
4. Keep the hydraulic cy linder needle valve i n
the same position and begin a second cut
on the same or similar workpiec e.
5. When t he blade has com pleted about 1/3 of
the cut, increase the f eed r ate.
Watch the chi p form ation until cutting is at its
most efficient rate and allow the saw to
complete the cut (refer to Evaluating Blade Efficiency below). The blade i s now consid-
ered ready for use.
Evaluating Cutting Efficiency
Is the blade cut ting efficiently ? The best way to
determine t hi s is to ob serv e t he chi ps f ormed by
the cutting blade.
If the chi p f ormati on is powdery, t hen the feed is
much too light or the blade is dull.
If the chips formed are curled, but color ed – blue
or straw colored f rom heat generat ed during t he
cut – then the feed rate is too high.
If the chips are slightly curled and are not
colored by heat – the blade is sufficiently sharp
and is cutting at its most efficient rate.
10
Setting the Work Stop
Referring to Fi gur e 5:
The work stop is an accessory that is included
with the JET J-9225 B andsaw. It is used to set
up the saw for maki ng multiple cuts of t he same
length.
Do not allow the blade to rest
on the workpiece when the saw is not
cutting.
Installation
1. Insert the distance set rod (A) into the hole
(B) at the front of the base as shown.
2. Secure by tightening the socket setscrew
(C) with a 3mm hex wrench.
Adjustment
3. The distance set br acket (D) is m oved along
the distance setrod (A) by loosening the
lock handle (E). The stop rod (F) can be
repositioned (G) by loosening lock handle
(H) and also by rotating the set rod (A) to
reposition the angle of the bracket (D).
Quick Release Vise Operation
Referring to Fi gur e 6:
The vise on the J-9225 bandsaw comes
equipped with a quick-release handle that
permits the workpi ece to be rapidly repositioned
or changed for a repeated cutting operation
while requir ing only one i nitial adjustment of the
vise handwheel. This is done as follows:
Figure 5
1. Place the quick-release handle (A) i n the up
position as shown.
2. Turn the handwheel (B) counterclockwise
until the workpiece can be placed in
position.
3. Place the workpiece (C) in the vise (D) and
against the work stop (E); turn the hand-wheel ( B) until the v ise begi ns to clamp ont o
the workpiece. T hen back t he han dwheel of f
just enough to perm it the workpiece t o slide
in and out of the vise.
4. Place the quick-release handle (A) in the
down positi on. The workpi ece is secure and
ready for cutting.
The vise is now set up for a repeated cutting
operation. Simply raise the quick-release
handle, reposit ion or replace the workpiece and
reset the handle down again.
Figure 6
11
Miter Cuts
Referring to Figure 7, the J-9225 band saw is
capable of making angle cuts from 0–60º. The vise
remains stati onary while the saw head is adj usted as
follows:
1. Place the saw head (F) in the raised position so
the blade doesn't catch in the table slots.
2. Set the lock handle (A) t o the unlock position as
indicated by the arr ows.
3. Using handles (B and C), rotate the saw head (F)
to any desired angl e within a range of 0º (square
cut) to 60º, setting it to the scale (D) on the base.
4. Set the lock handle (A) to the lock position.
Note: Two miter stops (E) on either side of the saw
base set the miter r ange of 0–60º. A djus t only if
necessary so t he saw tr av el stops at 0º and 60º.
Coolant Flow C on tr ol
The coolant pump must be
submerged before operating to prevent damage
to the pump.
Figure 7
A coolant pump, which provides coolant to the
workpiece, runs at all times when the machine is
turned on.
Two coolant flow control valves ( A , Fig. 8), located on
the top of the bearing blocks, contr ol the amount of
flow from the nozzles. Coolant flow should be
adjusted to be no m ore than the saw blade can draw
into the workpi ece by the mov ement of the bl ade. To
stop coolant flow, turn the control valves fully
counterclockwise.
Adjustments
Blade Guide Adjustment
Refer to Figure 9. The J-9225 Bandsaw has two
blade guide assemblies; one is stationary (A) and
mounted to the body of the saw head. The other,
consisting of a blade guide s uppor t or bracket (B) and
blade guide (C), is adj ustable.
The positi on of the blade guides is im portant in or der
to make acc urate cuts and prolong bl ade life and is
determined by the size of the workpi ece. Adjustment
is made as follows:
Figure 8
1. Place the workpiece (D) in the vise (E) and clamp
tightly.
2. Loosen the lock handle (F).
3. Slide the guide support (B) left or ri ght so that it
just clears the pi ec e to be cut (D) .
4. Tighten the lock handle (F ).
Figure 9
12
Bearing and Guide Block Adjustment
Referring to Fi gur e 10:
Guide bearings and c arbide guide b locks are l ocated
on either side of t he saw blade and provide stabilit y
for the blade when the saw is in operation. These
bearings rotate on an ec centric shaft so the distance
from the blade can be adjusted for optimal
performance.
Guide blocks provide additional blade stability.
Guide beari ngs and guide blocks ar e initially adjusted
at the factory and should rar ely require adjustm ent.
It is always better to try a new blade when cutting
performance is poor. If performance remains poor
after changi ng the blade, check the blade guides f or
proper guide bearing spacing. For most efficient
operation and maximum accuracy, clearance
between the blade a nd the g uide beari ngs should be
0.001-inch. The bearings will still turn freely with this
clearance. If the clearance is inc or r ec t, the blade may
track off the drive wheel.
Disconnect the bandsaw saw
from its electri cal power source.
If required, adjust the bearing and guide block on one
assembly then the other as follows:
1. Using a 3m m hex wrench, l oosen two set-screws
(A) that secure the ecc entric bushings.
2. Using a 4mm hex wrench, loosen the socket
head cap screw (E) securing the guide block (F).
3. With a 12mm wrench, loosen the hex nut (G) that
secures the guide block adjustment setscrew (H).
4. Position the bearings (B) by t urning the bushings
(C) with a flat-head screwdriver. Set the
clearance between the bearings (B) and blade
(D) at approximately 0.001 inch.
When properly adjusted, t he blade shoul d be in a
vertic al position between the beari ngs as shown
in Figure 11.
5. Secure the bushing settings by tightening the
setscrews (A).
6. With a 4mm wrench adjust setscrew (H) so the
guide block (F) supports the blade without
pinching the blade.
7. Tighten the soc k et head cap s crew (E).
8. Maint ain the position of t he setscrew (H) with the
hex wrench while ti ghtening the hex nut (G).

Limit Switch Adjustment
Refer to Figure 12.
The J-9225 bandsaw should shut off automatically
when a cut is completed. If not, the limit switch
probably needs to be adj usted as follows:
Disconnect the cut-off saw from
its electri cal power source.
1. Place the saw in the lowered po siti on to repres-
ent the completi on of a cutti ng oper ation
2. Using a crosspoint screwdriver and 5/16" wrench,
loosen two mounting screws (A).
3. Position the limit switch assem bly (B) to actuate
to the off positi on as it presses against the back plate (C) of the control panel when the saw has
cut through t he workpiece.

drive wheel (F ) and idler wheel (G) such that
the teeth face towards the rear of the saw
and the smooth side faces towards the front.
6. Push the blade so it seats against the
shoulders of the wheels (F, G).
Adjusting the proper B lade Tension
7. When it is seated agai nst the shoulder, t urn
the blade tension handle (J) clockwise to
increase the tension until the scale for the
1" blade tension measures 20–28KPSI (K)
(green zone) on the t ensi on indicator (L).
8. Replace the wheel cover (B) and blade guards (C, D) and brush (M).
9. Reconnect the saw to the electrical power
source.

Cleaning
Coolant
Clean off any preservative on machine surfaces.
After cleaning:
1. Coat machined surfaces of the cutoff saw
with a medium consistency machine oil.
Reapply the oil coating at least every six
months.
2. Clean up accumulated saw cuttings after
use. Make sure the lead screw and rapid nut
are kept free from saw cuttings and other
material that would c ause damage.
3. Cl ean the chi p sl udge f rom t he cool ant t ank.
The frequency shoul d be determi ned by how
often the saw is used.
Lubrication
Lubricate the following components at the
specified frequencies and using the lubricants
defined as follows:
Ball Bearings – the bearings are lubri cat ed and
sealed – periodi c lubri c ation is not required.
Blade Guide Beari ng – the bearings are lubri cated and sealed – periodic lubrication is not
required.
Change coolant on a frequency appropriate to
the type of coolant being used. Oil based
coolants can sour. Refer to the coolant
supplier’s instruc tions for change fr equenc y .
The general-purpose coolant is a mixture of
water-solubl e oil or synthet ic based coolant and
water. Mix one part of coolant to ten parts of
water (one quart of oil to ten quarts water).
Twelve quart s of coolant is the amount requi red
for the coolant pump to operate properly. Verif y
that the coolant level is visible in the indicator
(Figure 14).
There are num erous coolant s on the mark et that
are formulated for special applications. Consult
your local distributor f or details in t he event you
have a long range production task, or are
required to cut some of the more exotic
materials.
Wheel Bushings – si x to eight drops of oil each
week.
Pivot Poi nts, Shafts, and Bearingareas – six
to eight drops of oil eac h week.
