Grounding Instructions
This tool must be grounded while in use to protect the operator from electric
shock.
In the event of a malfunction or breakdown, groundi ng provides a path of least resistance f or electric
current to reduce the risk of electric shock. This tool is equipped with an electric cord having an
equipment-gr ounding conductor and a groundi ng plug. The pl ug must be plugged into a matc hing outlet
that is properly installed and grounded in acc or danc e with all local codes and ordinances.
Do not modify the plug provided. If it will not fit the outl et, have the proper outl et installed by a qualif ied
electrician.
Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The
conductor, with insulation having an outer surface that is green with or without yellow stripes, is the
equipment-gr ounding conduct or. If repai r or replacem ent of the electri c cord or plug i s necessary, do not
connect the equipment-grounding conduc tor to a live terminal.
Check with a qualified electrician or servi ce personnel if the grounding instructions are not completely
understood, or if in doubt as to whether t he tool is properly gr ounded. Use only three wire ex tension cords
that have thr ee- pr ong gr ounding plugs and three-pole recept ac les that accept the tool’s plug.
Repair or replace a dam aged or worn cord im mediately.
It is recommended that the PWBS-14CS Band Saw, when operated at 115 volts, be connected to a
grounded and dedi cated 30 amp ci rcuit with circuit breaker or time delay f use. When oper ated at 230
volts, c onnect t he saw to a 20 am p dedi cat ed ci rc uit with breaker or tim e del ay f use. Lo cal co d es take
precedence o ver recommendations.
115 Volt Operation
As received fr om the factory, your band saw is wired to run at 115 volt oper ation. This band saw, when
wired for 115 volts, is i ntended for use on a circuit that has an outlet and a plug that looks like the one
illustrated in Figure 2. A temporary adapter, which looks like the adapter illustrated in Figure 3, m ay be
used to connect this plug to a two-pole receptacle, as shown in Figure 3 if a properly grounded out let is
not available. The temporary adapter should only be used until a properly gr ounded outlet can be
install ed by a qualif ied electrician. This adapter is not applicable in Canada. The green colored ri gid
ear, lug, or tab, extending from the adapter, m ust be connected to a permanent gr ound such as a
properly grounded outlet box, as shown in Figur e 3.
Figure 2 Figure 3
230 Volt Operation
If 230V, singl e- phase operat ion is desired, the f ollowing instructions must be followed:
Disconnect the mach in e f rom the power sou rce.
This band saw is supplied with four motor leads that are connected for 115V operation, as shown in
Figure 4. Reconnect these four motor leads for 230V operation, as shown in Figure 5. These diagrams
are also found insi de the cover of the motor junction box.

Page 9
The 115V attachment plug (shown in Figure 6) supplied with the band saw, must be replaced with a
A
UL/CSA listed pl ug suit able f or 230V oper ati on (s hown i n F igur e 7). Cont act your l ocal aut hori zed Walt er
Meier (Manuf acturi ng) Inc., serv ic e center or qualifi ed elec trici an for pr oper proc edures to i nstall the pl ug.
The band saw must comply with all local and national codes after the 230 volt plug is installed.
The band saw with a 230 v olt pl ug should only be connec ted to an o utlet having t he same confi gurati on
(see Figure 7). No adapter is available or should be used with the 230 volt plug.
Important: In all cases (115 or 230 vol t s) , make certain the receptacl e in quest io n i s properly
grounded. If you are not su re, h ave a regi st ered el ectri cian check the recept acle.
NOTE: The lamp is designed fo r use wi th 115V power. I f the saw i s converted to 230V, discontinue
use of the lamp, and use an alt ernate lamp with an independent electrical source.

gain identical distance from tabl e top.
5. Ti ghten both screws in the rear r ail using a
10mm wrench.
Installing Front Rail and Rip Fence
Refer to Figures 26 t hr ough 29.
1. Install front rail (E, Figure 26) to the main
table using two M6x20 hex cap screws (HP4-L), two 1/4" lock washers ( HP 4- M ) and
two 1/4" flat washers (HP4-N). Finger
tighten only at t his tim e.
2. Install guide rail (B, Fi gure 27) to the slot s in
the front rail using three M6x20 hex cap
screws (HP4-L), three 1/4" lock washers
(HP4-M) and three 1/4" flat washers (HP4-
N). Tighten with a 10mm wrench.
3. Attach the fence (C, Fi gure 28) to the fence
body (P) with four 5/16”x3/4” hex cap
screws (HP4-H), four 5/16” lock washers
(HP4-J) and four 5/16” flat washers (HP4-K).
Tighten the screws with a 12mm wrench.
4. At the rear of the fence, thread a 1/4” hex
nut (HP4-D, Figure 29) onto the sliding pad
(HP4-G) and insert the sliding pad through
the fence and r ear hook (HP4-C). Secure in
place using a 1/4” flat washer (HP4- E), 1/4”
lock washer (HP4-F) and a 1/4” hex nut
(HP4-D). The rear hook should be adj usted
so that it overlaps the rear rail by
approxim ately 1/8".
Figure 26
Figure 27
5. Hook t he fence assembly over the rear rail,
and onto the guide rai l, as shown in Fi gure
28.
6. When t he fence assembl y is placed on the
table, the rear hook (HP4-C) should be
almost contac ting the undersi de of the rear
rail, as shown. The sliding pad will ride
along the top of the rear r ail.
Setting Fence-to-Table Gap
The gap between the bottom of the rip fence
and the table t op should be high enough that the
fence will not scrape along the table, yet low
enough that thi n workpieces won’t slip beneath
it. The gap should be equ al along the l ength of
the fence. Adjust as follows:
Refer to Figures 29 and 30.
1. Lock the f ence assembly t o the front rail by
pushing the fence handle down. The front
rail screws should still have “play” in them.
2. Lift up on bot h guide rail and fence toget her
until the f ence/table gap at the front edge of
the table is acceptable.
Figure 28
Figure 29

Page 17
3. Tighten bot h scr ews on the front rail (HP4-L,
Figure 26) with a 10mm wrench.
4. Adjust the height of the sliding pad at the
rear of the fence (Figure 29) if further
adjustment i s needed to even the gap along
the length of the fenc e.
Aligning Fence to Blade
Refer to Figure 31.
1. Place the table at 90-degrees. (Make sure
the 90° Tabl e Stop sett ing has been v erifi ed
– see page 20.)
2. Lock the fence to the guide rail with the
handle.
3. Place a square on t he table and agai nst the
fence, as shown in Figure 31.
4. If the fence is not square to the table,
slightly loosen the two screws in the front
rail (see Figure 26) and raise or lower one
end of the f ront rail assembly until f ence is
square to table.
5. Re-tighten screws. The fence face is now
square to the tabl e, and thus parallel to the
blade.
The fence must al so be set so that it aligns wit h
the blade front- to-back, as follows:
6. Move the fence so that it just contacts the
blade without bendi ng it, and lock t he fence
to the guide rail.
7. Check that the fence is aligned with the
blade; that is, it contacts front and back of
blade evenly. If the fence does not al ign with
the blade, loosen the four hex cap screws (HP4-H).
8. Align t he fence wit h the blade, t hen tighten
the four hex cap screws.
Figure 30
Figure 31
Checking zero setting
Refer to Figure 31.
1. With the fence now aligned with the blade,
and still contacting the blade as shown in
Figure 31, check to see that the pointer is
aligned wit h zero on t he guide r ail scale.
2. If minor adjustment i s necessary, l oosen the
screw that holds the pointer in place, and
adjust the poi nter. Re-tighten the screw.
3. If major adjustment i s necessary, l oosen the
guide rail screws (HP4-L, Figure 27), and
slide the entire fence/ guide rail t ogether until
the fence just contac ts the bl ade. Re- ti ghten
guide rail screws, and make further minor
adjustment wit h the pointer.

Page 18
NOTE: The pointer’s zero position should be
tested later by cutting a straight piece of stock,
carefully measuring its width, and comparing it
to the scale reading.
Resaw Guide
Refer to Figure 32.
For resawing operati ons, att ach the r esaw guide
(HP4-A) to the fence using the knob (HP4-B)
through the slotted hole. Position the resaw
guide so that it is centered approximately with
the front edge of t he saw blade.
The resaw guide offers a taller, single-point
contact surface that allows pivoting of the
workpiece in order to keep the blade on the
cutting line.
Blower Nozzle
Refer to Figures 33 and 34.
1. The air hose, which is already connected to
the saw body, should be inserted through
the hole in the stand (visible in Figure 16)
and connected to the nozzle of the air
regulator on the motor (Figure 33). Use a
lighter or match to briefly heat the end of the
hose so that it will slip over the nozzle. A s it
cools, it will form a tight seal over the
nozzle.
Figure 32
Figure 33
2. Attach the plate (HP1-A) to the blade guide
assembly.
3. Connect the top end of the air hose to the
plate (HP1-A) with the M5x12 pan head
screw (HP1-D) through the cord clamp
(HP1-C). Heat the end of the hose with a
lighter or m atch, then push the wide end of
the nozzle (HP1-B) into the hose; the
tapered end points down toward the tabl e as
shown.
Work L amp
Refer to Figure 35.
The goose-neck l am p uses a m edium base l ight
bulb (not prov ided) which should be 60 watts or
less. The work lamp is operated independentl y
of the main saw switch.
IMPORTANT: If you are using 115 volt power
for the band saw, use a standard 110 v olt light
bulb. If you are using 230 volt power for the
band saw, discontinue use of the prov ided lamp,
and use an alternat e lamp with an independent
power cord.

Installing Quick Tension Lever
Refer to Figure 36.
Install the quic k tension lever (M) onto the shaft
as shown, and tight en the two set screws using
a 3mm hex wrench. T he m ov ement of t he blade
tension lever is explained under “Installing
Blades”.
Stand Attachments
Refer to Figure 37.
1. Mount the two miter gauge hooks (HP3-B)
to the side of the stand with two M8x16
carriage bolts (HP 3-E) and two M8 flanged
hex nuts (HP3-F ). Position the hooks at an
angle, similar to that shown in Figure 38.
The miter gauge can be stored in these
hooks.
2. Mount the blade hook (HP3-C) with two
M4x10 pan head screw s (HP3- H) as shown.
The blade hook can store a roll ed-up spare
blade.
3. Mount the two fence hooks(HP3-A) to the
opposite side of the stand with two M8x16
carriage bolts (HP 3-E) and two M8 flanged
hex nuts (HP3-F). The rip fence can be
stored in these hooks when not i n use.
Dust Collection
Refer to Figure 38.
The use of a dust collection system (not
provided) is strongly advised when using the
band saw. It will hel p keep your shop clean, and
reduce the ri sk of heal th problems due to wood
dust inhalation. The dust collector should have
sufficient capacity for this size band saw
(minimum 350 cubi c feet per mi nute).
Figure 36
Figure 37
Connect a 4” diam eter dust coll ection hose (not
provided) to the port at the back of the band
saw, and secure tightly with a hose clamp, as
shown.
Note: Dryer vent hose is not suitable for dust
collection pur pose s.
Riser Block Accessory
A Riser Block kit (stock no. 1791217, not
provided) is available as an accessory. When
install ed, it increases resaw capacit y (workpiece
height capacity) to 12 inches. If you have
purchased the Riser Block, consult the
instruction sheet that accompanies it.

Adjusting 90° Table Stop
Refer to Figures 39 and 40.
1. Disconnect machine from power source.
2. Loosen tabl e locking knobs and tilt table t o
the left until it rests against the table stop
screw.
Figure 39
3. Use a square placed on the table and
against the bl ade, as shown in Figure 40, to
verify that the table is 90 degrees to the
blade. Make sure the table insert is level
with the table surface, to ensure an acc ur ate
reading.
4. If an adjustm ent is necessary, tilt the table
out of the way and tight en the table locking
knobs.
5. Loosen jam nut (Figure 39) and turn table
stop screw left or right to raise or lower the
stop. Tighten jam nut down against the
trunnion support t o hold table stop screw in
place.
6. Unlock the table and tilt it back on to the
table stop screw to confirm table is 90
degrees to the blade. Repeat this process
as necessary unti l tabl e is 90 degrees to the
blade.
7. Make sure pointer (Figure 39) indicates
zero. If it does not, l oosen screw and mov e
pointer to align wi th zero. Re-tighten screw.
NOTE: After adjusting the 90-degree stop, it
may be necessary t o re-set the ext ension table
so it is level with the main tabl e. See “Leveling
the Extension Table. ”

Table Aligned with Blade
For accurate crosscuts using the miter gauge,
the table (i.e. miter slot) must be aligned with the
blade. This alignment has been set by the
manufacturer, but the operator may wish to
verify it, as follows. NOTE: This procedure
works best with a wide bl ade.
Refer to Figure 41.
1. Place a straightedge along the side of the
blade, with very light pressure (do not
deflect the blade). The straightedge should
contact bot h front and back of blade.
2. Measure carefully with a fine rule from the
straightedge to the edge of the miter slot.
Do this at front and back of the table; the
distance should be the same.
3. If the mit er slot is not aligned wit h t he blade,
slightly loosen the six screws holding the
trunnions to t he table.
4. Nudge the table as needed, until the miter
slot is aligned wit h blade (distances are the
same front to back ).
5. Tighten trunnion screws. (NOTE: After this
adjustment, the alignment of fence to blade
may need to be re-checked. See “Aligning
Fence to Blade” on page 17.)
Figure 41
Installing Blades
Unplug the machine from the
power source before removing or installing
blades.
The PWBS-14CS Band S aw is provi ded with a
3/8” wide x 0.020 thi c k x 93.5” long, 6TPI blade.
Refer to Figure 42.
The blade tension lever is a patented Carter®
Quick-Rel ease™ lever, and has three positions:
high (tension) , mi ddle (partial tension), and low
(blade rel ease). Push the lever up slightly, then
out, and mov e it into positi on, allowing it to rest
on the appropriate ledge of the block.
1. Disconnect machine from power source.
2. Move tension lever to blade release
position, as shown in Fi gur e 42.
(Note: When using t he larger width blades,
it may also becom e neces sary to l oosen t he
tension knob to release al l tension.)
3. Remove the table insert and the table pin.
4. Open both wheel guards.
5. Back off t he upper and lower guide beari ngs
so that nothing conflicts with the blade.
Figure 42
21
Page 22
6. Remove the current blade from the upper
wheel, then t he lower wheel. Turn blade to
direct it through t he sl ot in the table.
New blades are usually
packaged in co iled position. Use gloves and
grasp the coil with one hand while slowly
uncoiling the blade with the other hand.
7. Guide new blade through table slot. Place
blade in upper and l ower blade guide s, and
around upper and lower wheels.
Note: Make sure blade teeth point forward
and down toward t he table. If the teeth won’t
point downward no matter how you orient
the blade, then the blade is twisted insideout. Remove blade and, usi ng gloves, twist
it into correct ori entation, then re-install.
8. Position blade so it lies on t he c enter of bot h
upper and lower wheels.
9. Raise tension lever to partial tension
position.
10. Re-install table insert and table pin.
11. Tension and track the blade before
operating saw. Proceed to "Blade Tension"
and “Blade Trac k ing" .
Blade Tension
Refer to Figure 43.
1. Disconnect machine from power source.
2. Place tension lever in full tension position
(see Figure 42).
3. Turn blade tension knob (Figure 43)
clockwise to t ension blade. A gauge on the
upper wheel slide bracket indicates the
approximate tension according to the width
of the blade. Initially, set the blade tension
to correspond to bl ade width.
The ten sion lever must b e in
highest (tension) position when setting blade
tension. Failure to comply may cause
damage to locating block at base of lever.
As you become fami liar 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. Keep in mind that too
little or too much blade tension can cause bl ade
breakage.
Figure 43
TIP: If the band saw is to sit idle for a period of
time while the blade is installed, place tension
lever in partial tension position; this will help
prevent blade f atigue and tire deform ation, and
save wear on bearings and band wheel s.

Blade Tracking
Disconnect machine from
power source. Do not adjust blade tracking
with the machine running.
“Tracking” r efers to how the blade is posit ioned
on the wheels whil e in moti on. The bl ade should
track approximately in t he c enter of both wheels,
as shown in Fi gure 44. Track ing on the PW BS14CS Band Saw has been factory-adjusted;
however, it should be checked periodically,
including aft er ev er y bl ade c hange.
Refer to Figure 45.
1. The blade must be properly tensioned
before adjusting blade tracking. Make sure
blade guides and blade bearings do not
interfere with the blade.
2. Place the tension lever at full tension
position.
3. Open the upper door and rotate the upper
wheel forward by hand. Observe the
position of the blade on t he wheel - it should
be in the center.
Figure 44
4. If the bl ade tends to shift t o one side or the
other of the wheel, loosen wing nut (Figure
45).
5. If the blade i s tr acki ng toward the f ront edge
of the wheel, rotate the tracking knob
clockwise – the upper wheel will tilt toward
the back and the blade will move to the
center of the wheel.
If the bl ade is tracking toward the back edge
of the wheel, rotate the tracking knob
counterclockwise: the upper wheel will tilt
toward the f ront and the blade will move t o
the center of the wheel.
IMPORTANT: This adjustment is sensitive;
perform it in small increment s and give the
blade time to react to the changes, as you
continue to rot ate the wheel.
6. When blade is tracking properly at the
center of the wheel, r e- tighten the wing nut.
7. Turn on saw and verify proper tracking while
the machine is running.
8. If further tracking adjustments are needed,
disconnect from power, and repeat
instructions above.

1. Disconnect machine from power source.
2. Blade must already be tensioned and
tracki ng properly.
3. Loosen thumb screw (A, Figure 47) and
move guide block by turning knob (B) so
that the front of the guide wheels (C) are
just behind the gullet (curved area at base
of tooth) of the blade, as shown in Figure
48. This di stance is usually about 0.016” ( or
1/64”).
4. Tighten thumb screw (A, Figure 47).
5. Loosen the socket screw (D) and turn the
screw (E) on each guide wheel to m ov e the
guide wheels about 0.004” from the blade.
(A quick way to set t his distance is t o place
a crisp dollar bill, which is approximately
.004” thic k, between guide wheel and bl ade,
and move t he guide until it just contact s the
bill.)
6. Tighten socket screw (D) when adjustment
is satisfactory.

Thrust Bearing
The thrust bearing (F, Figure 49) supports the
back edge of t he blade during operat ion, and is
set so that the blade will c ontact it only when the
blade is under pressure during a c ut.
7. Loosen thumb screw (G, Figure 49) and tur n
knob (H) to move the thrust beari ng (F) in or
out until t he bearing is approxim ately 0. 016”
(or 1/64”) behi nd the blade. You can use a
feeler gauge to set this distance, or simply
place a crisp dollar bill folded twice (four
thicknesses) between the thrust bearing and
the blade. (A dollar bill is approximately
0.004” thick, so four thicknesses provides
the necessary distanc e.)

A miter gauge is provi ded for crosscutti ng. Slide
the miter gauge i nto the T-slot from the edge of
the table.
To use the mit er gauge, loosen the handle and
rotate the gauge body u nt il t he desired angl e on
the scale lines up with the pointer. Tighten
handle.
For preci se crosscuts, t he 90° angl e of t he mit er
gauge to the blade can be verified as follows
(Refer to Figure 52). A wide blade works best for
this procedure.
1. Set the miter gauge at 90°.
2. Place a square agai nst the mi ter gauge and
against the bl ade, as shown.
3. Adjust t he miter gauge until t he square lies
flush against bot h it and the blade.
4. Loosen the screw and shift the pointer as
needed. Retight en scr ew.
The miter gauge, when not in use, can be
placed int o the hooks on the stand. See Figur e
53. Loosen the miter gauge handle, and slide
the miter gauge into the top hook. Pivot the
miter gauge bar into the lower hook, then tight en

On/Off Switch
The band saw is equipped with a push-button
switch that will accept a safety padlock (not
included). To safeguard your machine from
unauthorized operation and accidental starting
by young chil dren, the use of a padl ock is hi ghly
recommended – see Figur e 54.
Maintenance
Before doing maintenance,
disconnect machine from electrical supply
by pulling out the plug or switching off the
main switch! Failure to comply may cause
serious injury.
Clean the band saw regularly to remove any
resinous deposits and sawdust. Use a brush,
vacuum or compressed air to blow out excess
dust. (Wear safet y goggles while doing this.)
Keep the mit er slot in the table free of dust and
debris. Keep the gui de bearings clean and free
of resin. Use a commercially avail able gum and
pitch remover if needed.
Keep the guide po st clean; occasionall y apply a
light coat of oil.
Oil any pi ns, shaf ts, and j oi nts. Do not get oi l on
pulleys or belt s.
Bearings on the band sa w are sealed for life and
do not require att ention.
Check that the cleaning brush over the lower
wheel is working proper ly; adjust if necessary.
Remove any deposits from the band wheels and
tires to avoid vibration and blade breakage.
NOTE: Do not use s olv ents around tires. If signs
of wear or deform ation occ ur , replace the tires.
Figure 54
The table surf ac e m ust be k ept clean and fr ee of
rust for best results. If rust appears, use a
mixture of household ammonia, a good
commercial detergent and #000 steel wool.
Alternatively, commercial rust removers can be
found at many hardware stores.
Apply a light, protective coating over the table,
such as paste wax. Product s in aerosol f orm are
also available in hardware stores and supply
catalogs. Whatever method is chosen, the
coating should protect the metal and provide a
smooth surf ac e, wit hout staining the wood.

Blade Selection
Using the proper bl ade for the job will incr ease
the operating ef ficiency of your band saw, help
reduce necessary saw maintenance, and
improve your pr oduc tivity. Thus, it is import ant to
follow certain guidelines when selecting a saw
blade.
Here are factors to consider when selecting a
blade:
• The type of materi al y ou will be c utti ng.
• The thickness of the workpi ec e.
• The features of the workpiece, such as
bends or curves wit h small radii.
These factors are important because they
involve basic concepts of saw blade design.
There are five (5) blade features that are
normally changed to meet certain kinds of
sawing requirements. They are:
1. width
2. pitch (number of teeth per inch)
3. tooth form (or shape)
4. the “set” of the teeth
5. the blade material itself
A fine pi tch (more teet h per inch) will cut slowly
but more sm oothly. A coar se pitch (f ewer teeth
per inch) will cut f aster but more roughly.
As a rule of thumb, the thicker the workpiece,
the coarser will be the bl ade pitch. If you have to
cut a hard or very brittle material, you will
probably want to use a blade wit h a finer pitch i n
order to get clean c uts.
Using a blade with too few teeth may cause
vibration and a r ough cut, while too m any teeth
may cause the gullets to fill with sawdust and
overheat the blade.
As a general rule, try to use a blade that will
have from 6 to 12 teeth in the workpiece at any
given time.
Shape
Figure 56 shows comm on types of t ooth shape,
or form. Tooth shape has an effect on cutting
rate.
Width
Band saw blades come in different standard
widths, measured from the back edge of the
blade to the tip of the tooth. Generally, wider
blades are used for ripping or making straight
cuts, such as resawing. Narrower blades are
often used when the part being cut has curves
with small r adii. When cut ting straight lines with
a narrow blade, t he blade may hav e a tendency
to drift (see “Bl ade Lead” ) .
Pitch
Pitch is m easured in “ teet h per i nch” ( T. P.I.) and
can be constant or variable. Figure 55 shows
blades with different pitches.
Figure 56 – Blade Toot h Shape
The Regular, or standard blade, has evenly
spaced teeth that are the same size as the
gullets, and a zero-degree rake (i.e. cutting
angle). T hese offer precise, cl ean cuts at slower
rates. It is usually a good choice for cutting
curves and making cr osscuts.
The Skip type has fewer teeth and l arger gullet s
with a zero rake. It allows faster cutting rates
than the Regular type, with a slightly coarser
finish. It i s useful for re-sawing and rippi ng thick
stock, as well as cutti ng softwoods.
The Hook ty pe blade has l ar ger teeth and gullet s
and a positive rake angle for more aggressive,
faster cutting when re-sawing or ripping thick
stock, especially hardwoods.
Figure 55
Variable-tooth blades combine features of the
other shapes, with tooth style and spacing
varying on the same blade. This produces
smooth cuts whil e dam pening v ibration.
27
Page 28
Set
The term “set” ref er s to the way in which the saw
teeth are bent or positioned. Bending the teeth
creates a kerf that is wider than t he back of t he
blade. This hel ps the operator m ore easily pivot
a workpiece through cur ve cuts, and decrease s
friction bet ween blade and workpi ece on strai ght
cuts.
Set patterns are usually selected depending
upon the type of material that needs to be cut .
Three comm on set patt erns ar e sho wn in F i gure
57.
Blade Breakage
Band saw blades are subject to high stresses
and breakage may sometimes be unavoidable.
However, many f actor s can be controlled t o hel p
prevent most blade breakage. Here are some
common causes for break age:
1. Misalignment of the blade guides.
2. Feeding workpiec e too quickly.
3. Using a wide blade to cut a tight radius
curve.
4. Excessive tension.
5. Teeth are dull or impr oper ly set.
6. Upper guides are set too high off the
workpiece.
7. Faulty weld on bl ade.
Although not essential, some users round or
“stone” the back edge of their blade. This is
done by placing a s harpeni ng stone on the tabl e
and in li ght contact with t he back corners of t he
blade as the blade is running. Rounding can
help the back blade edge m ove more smoothly
through the kerf, smooths the weld, and helps
prevent crack s fr om start ing at the back corners.
Figure 57
Generally, the Raker set is used for cutting
metal workpieces; the Wavy set, when the
thickness of the workpiece changes, such as
cutting hol low tubi ng or struc tural s. The Straight,
or Alternate, set is the one most used for
woodworking blades, and is also used to cut
plastics.
Material
Band saw blades can be made from different
types of metals. The most common include
spring steel, carbon steel, bimetal (alloy steel
equipped with a high speed cobalt steel edge
welded to it), or carbide tips.
Because of the im portance of blade sel ection, it
is recommended that you use the blade
selection guide on page 35. Also, listening to
experienced band saw users will provide
valuable information as to the types of blades
currentl y on the market along wit h their pros and
cons.

Operation
The following sect ion c ontains basic i nf ormati on,
and is not intended to cover all possible
applicati ons or techniques using the Band Saw.
Consult published sources of information,
acquire formal training, and/or talk to
experienced Band S aw us ers t o gain pr of i ciency
and knowledge of band saw operations. (The
Figures used may or may not show your
particular saw model, but the procedures are
identical.)
General Procedure
1. Make sure t he bl ade is adj usted correc tly for
tension and tracking, and that upper and
lower guide beari ngs and thr ust bear ings are
set in proper relati on to the blade.
Ripping
Ripping is cutting lengthwise down the
workpiece, and with the grain (of wood stock).
See Figure 58. Always use a push stick or
similar safety device when ripping narrow
pieces.
2. Adjust gui de post so that the guide bear ings
are just above the workpiece (about 3/16”)
allowing minim um ex posure t o the blade.
3. If using the f ence, move i t into position and
lock it t o the guide rail. If you are usi ng the
miter gauge for a crosscut, t he fence should
be moved safely out of the way.
4. Turn on the band saw and allow a few
seconds for t he machine to reach full speed.
Whenever possible, use a
push stick, hold-down, power feeder, jig, or
similar device while feeding stock, to prevent
your hands getting too close to the blade.
5. Pl ace the straightest edge of the workpiece
against the f ence f or a rip c ut; or against t he
miter gauge for a crosscut. Push the
workpiece slowly into the blade, while also
keeping it pressed again st the f ence or held
against the miter gauge. Do not force the
workpiece int o the blade.
Some further operat ing tips:
Make relief cuts whenever possibl e. A relief cut
is an extr a cut made through t he waste porti on
of a workpiece up to the layout line. When that
intersection is reached by the blade while
following the layout line, the waste portion
comes free. This helps prev ent pinching of the
back edge of the blade in t he cut.
Figure 58
Crosscutting
Crosscutting is cutting across the grain of the
workpiece, while using the miter gauge to feed
the workpiece i nto the blade.
The right hand shoul d hold the workpiece steady
against the miter gauge, while the left hand
pushes the miter gauge past the blade, as
shown in Figure 59.
Figure 59
Do not use the fence in conjunction with the
miter gauge. The offcut of the workpiece must
not be constrained during or after the cutting
process.
When cutting, do not
overfeed the blade; overfeeding will reduce
blade life, and may cause the bl ade to break.
When cutting long stock, the operator should
use roller stands, suppor t tabl es, or an assistant
to help stabilize the workpiece.
Using the fence in
conjunction with the miter gauge can cause
binding and possible damage to the blade.

Resawing
Resawing is the process of slicing stock to
reduce its thickness, or to produce boards that
are thinner t han the origi nal workpiece, such as
veneers.
The ideal bl ade for resawing is the widest one
the machine c an handle, as the wider the bl ade
the better it can hold a str aight line.
Resawing can be per formed using t he rip f ence
or the resaw guide. When using the rip fence,
use a push block, push stic k, or simil ar device to
keep your hands away from the blade. The
resaw guide offers a pivot point by which you
can carefully follow your layout line; it is
especially useful for sawing curves, when the
fence can’t be used and it’s difficult to c ontrol the
cut freehand.
Figure 60 demonstrates resawing with the rip
fence; Figur e 61, wit h the resaw guide.
It is more common with small, narrow blades,
and is almost always attributable to poor blade
quality, or lack of proper adjustments. Inspect
the band saw for the following:
• Fence is not parallel to miter slot and blade.
• Blade is not tensioned c or r ec tly.
• Blade is dull.
• Teeth have too much “set” on one side of
the blade.
•Workpiec e is bei ng fed t oo quic kl y.

Figure 61
Blade Lead
Blade lead, or drift, is when the blade begins to
wander off t he cutting li ne even when the band
saw rip fence i s being used. Figur e 62 shows an
example of blade lead.
If the blade is suspect, but replacing it is not
currently an option, the blade lead can be
temporarily compensated for by skewing the
fence:
1. Cut a scrap pi ece of wood about the same
length as the band saw tabl e, and joint one
edge along its lengt h, or rip it on a table saw
to give it a straight edge.
2. Draw a line on the board parallel with the
jointed, or str aight edge of the board.
3. Move the band saw fence out of the way,
and carefully make a freehand cut along
your drawn line on the board. Stop about
midway on the board, and shut off the band
saw (allow the blade t o come to a complete
stop) but do not all ow the board to move.
4. Clamp the board to the table.
5. Loosen the four hex cap screws on the
fence and slide the fence over, lining it up
against the board. Loc k the f enc e down.
6. Re-tighten the four hex cap screws.
NOTE: Skewing the f ence to correct blade lead
is effectiv e for that particular blade; when a new
blade is installed, the fence will need readjustment and re-squaring to miter slot. See
appropriate sect ions in this manual.

Blade Selection Guide
Identify the material and thickness of your workpiece. The chart will show the recommended PITCH,
blade TYPE, and FEE D RATE.
Key: H – Hook L – Low S – Skip M – Medium R – Regul ar H – High
Example: 10/H/M means 10 teeth per inch / Hook Type Blade / Medium Feed
For Radius Cutting
Study the part drawing or prototype, or actually
measure the small est cutting radius required, and
locate this radius (in inches) on the chart at the
right. Follow the curve to where the approxim ate
blade width is specified. If a radius falls between
two of the curves, selec t the widest blade that will
saw this radius.
This procedure should be used for making initial
blade selecti ons. These recommendations can, of
course, be adjusted to m eet specific requir ements
of a cutting job. Compromises may be nec essary if
you cannot find all needed specifications in a
single blade.
