Section 1: General Information
You have purchased a quality machine tool, and you will want to give
it good care.
To derive maximum satisfaction from the use of your bandsaw,
become familiar with the contents of this manual.
Section 2: Inspection
When you receive your machine, look it over carefully.
Should any shipping damage be noticed, report it promptly to the
shipping carrier or directly to the factory, for fast claim service.
Section 3: Location of Installation
Select a convenient well lighted work area having sufficient room to
allow long stock to be easily positioned in the saw.
Place the saw on a firm level surface. Be sure that there is sufficient
clearance for raising the saw head to its vertical position.
Section 4: Cleanliness
As with all machinery, cleanliness is of utmost importance.
This machine and the general work area should be kept clean at all
times.
Section 5: Installation
5.1 Remove the slipping bolts from the saw and saw legs.
5.2 Slide the saw out of the shipping crate and place it on some type
of temporary support.
5.3 Bolt the saw legs to the saw using the bolts provided for this
purpose located in the bolt kit at tached to the saw blade.
5.4 Remove the shipping bolt that locks the saw head to the base of
the saw.
Section 6: Safety Precautions
6.1 Before cleaning this machine, or before doing any machine
maintenance, disconnect the power supply.
6.2 Never use an air hose for cleaning purposes,
—instead, use a hand brush.
6.3 Never place your hands in the direct line of the saw blade, — use
a “stock pusher to push against the stock.
6.4 Do not force the material into the saw blade.
6.5 Do not twist the material in the saw blade, — make curved cuts
graduallywithout binding the blade.
6.6 Do not use a saw blade that has teeth missing from it.
6.7. Never operate this saw without the blade guides in place.
6.8 This tool should be grounded while in use to protect the operator
from electric shock. Replace or repair damaged or worn cord
immediately.
6.9 Wear proper apparel.
6.10 Use safety glasses.
Section 7: Lubrication
Lubricate the following parts using SAE-30 weight MOTOR oil.
7.1 THRUST BEARINGS (ltems29)from 6-8 drops each week.
7.2 BLADE-GUIDE BEARINGS (Items 20) none required.
7.3 VISE ADJUSTING-ROD as needed.
7.4 All other pivot points, shafts and bearing areas,
6-8 drops each week.
The heavy duty GEAR REDUCER requires a medium weight GEAR
oil (Item 63) available from the factory.
Section 8: Blade Selection
Your bandsaw comes to you fully equipped with a good general
purpose saw blade of moderate coarseness (Item 33.3).
The type of material that you wish to cut will determine the tye of saw
blade to be used.
Solid material requires a COARSE blade (fewer number of teeth per
inch) and lighter guage material requires a FINE blade (greater
number of teeth per inch.)
The blade size required for this bandsaw is 3/4” wide x 115-1/2” long.
This length is equal to 9-7- 1/2’.
The saw blade grips on this bandsaw can accom modate various blade
thicknesses.
Section 9: Cutting Speed Selection
This bandsaw is provided with a step pulley drive arrangement that
provides the ability to select any one of three cutting speeds.
9.1 FAST, — 153 Feet Per Minute
9.2 MEDIUM, — 108 Feet Per Minute.
9.3 SLOW, — 55 Feet Per Minute.
For SOFTER materials, use a FASTER cutting speed, — for
HARDER materials, us a SLOWER cutting speed.
Section 10: Cutting Speed Adjustment
10.1 FOR FAST CUTTING SPEED, — set the V BELT (Item 6) in
the LARGEST pulley groove of the MOTOR PULLEY (Item 7) and
in the SMALLEST pulley groove of the REDUCER PULLEY (Item
5).
10.2 FOR MEDIUM CUTTING SPEED,— set the V-BELT in the
MIDDLE pulley groove of BOTH pulleys.
10.3 FOR SLOW CUTTING SPEED, — set the
2

V-BELT in the SMALLEST pulley groove of the MOTOR PULLEY
(Item 7) and in the LARGEST pulley groove of the REDUCER
PULLEY (Item 5).
10.4 The V-BELT is easily positioned by swing ing the spring loaded
DRIVE MOTOR (Item 1) downward while moving the V-Belt to the
desired position in the step pulleys, and then releasing the spring
loaded DRIVE MOTOR to re-tighten the V Belt.
Section 11: Cutting Speed Chart
The following Chart gives suggested settings for several materials.
For detailed cutting data, check any good machinist handbook and use
the closest speed available.

Section 12: Saw Blade Removal
12.1 Turn the BLADETENSION ADJUSTER (Item
13) counterclockwise allowing the WHEEL AXLE ASSEMBLY
(Items 12 & 27) to move inward along the GUIDE BLOCKS (Item
28) thereby loosening the saw blade, — permitting it to be removed
from the BLADE WHEELS (Items 30.1 & 30.2)
Section 13: Saw Blade Installation
13.1 Place the appropriate blade onto the BLADE WHEELS (Items
30.1 & 30.2) and in between the GUIDE BEARINGS (Items 20)
being sure that the smooth back edge of the blade is close to the blade
bacKup flange on both blade wheels.
Be sure that the blade teeth are pointed in the right direction, —
toward the motor end of the saw.
13.2 Re-tighten the BLADE TENSION ADJUSTER (Item 13) which
pushes the wheel axle assembly back out along the GUIDE BLOCKS
(Items 28)
thereby tightening the saw blade just enough to track align itself.
13.3 Check to be sure that the blade is properly installed and freely
fitting in the BLADE GUIDES.
13.4 Inch the saw to make a complete revolution of the saw blade, to
check for proper tracking.
13.5 Apply the correct tension to the saw blade,
— that tension which will allow the blade to be deflected 1/8”
sideways from its true position.
13.6 Run the saw again to check for proper blade tracking.
For more extensive tracking adjustment, see Section 11.
Section 14: Saw Blade Tracking Adjustment
Correct saw blade tracking has been factory adjusted. However,
should you find it necessary to re-adjust the tracking of the saw blade,
proceed as follows.
14.1 Slightly loosen the bolts that fasten the WHEEL AXLE (Item 12)
to the ADJUSTMENT BRACKET (Item 27).
14.2 Change the tilt of the WHEEL AXLE just a small amount by
turning the two adjustment bolts in” or “out” as the case may require,
— to track the smooth edge of the saw blade approximately 1/16”
away from the blade backup flange on each BLADE
WHEEL.
Also, the tilt angle of the drive shaft of the GEAR REDUCER (Item
4) can be adjusted in like manner,
— but this adjustment should be made only if the blade will not
otherwise track by the above adjust ments.
Section 15: Saw Blade Grip Adjustment
The BEARING GUIDE assemblies (Items 18) can be adjusted to
accommodate different blade widths. This is accomplished as follows:
15.1 Loosen the blade guide HEX NUTS (Items
15).
15.2 Turn the ECCENTRIC BOLTS (Items 21) until the BLADE
GUIDE BEARINGS (Items 20) lightly grip the saw blade.
15.3 Re-tighten the blade guide HEX NUT while holding the
ECCENTRIC BOLT in its position.
When properly adjusted, the BLADE GUIDE BEARING should be
just barely turriable by hand.
Section 16: Saw Blade Pitch Adjustment
16.1 Loosen the bolts that attach the BLADE GUIDES (Items 18) to
the right hand and the left hand BLADE GUIDE CARRIAGE (Items
16 & 22).
16.2 Rotate the BLADE GUIDES clockwise or counterclockwise to
set the correct pitch of the blade.
If the blade is cutting “in” at the bottom of the stock
3

material, adjust the blade pitch outward.
If the blade is cutting “out” at the bottom of the stock material, adjust
the blade pitch inward.
16.3 Re-tighten the blade guide mounting bolts. If all adjustments are
correct, the blades should lightly touch all BLADE GUIDE
BEARINGS (Items 20).
16.4 Check settings by making sample cuts in scrap stock before
doing production work.
Section 17: Adjusting the Clamp Vise
17.1 FOR ALL CUTS, — set the STATIONARY VISE JAW tern 50)
as close as possible to the right hand BLADE UIDE ASSEMBLY
(Item 18).
17.2 FOR SQUARE CUTS, — set the face of the STATIONARY
VISE JAW so that it is “square” with the saw blade, — to ensure
accurate “square” cuts horizontally across the stock material.
17.3 FOR ANGLED CUTS, —set the face of the STATIONARY
VISE JAW at the desired cut-angle with reference to the saw blade.
17.4 FOR PARALLEL STOCK, set the angle of the MOVEABLE
VISE JAW (Item 49) parallel to the STATIONARY VISE JAW.
17.5 FOR NONPARALLEL STOCK, — set the MOVEABLE VISE
JAW parallel to the stock mate rial, after it has been set in place on
the sawbed.
Section 18: Work Setup
18.1 Raise the saw head to its highest position.
18.2 Open the vise to accept the piece to be cut,
— by raising the CLAMP BAR (Item 47) on the MOVEABLE VISE
JAW (Item 49). Then slide it away from the STATIONARY VISE
JAW (Item 50).
18.3 Place the workpiece on the saw bed (Item
54). Long bar stock should be supported by a tripod type stand at the
same height as the saw bed.
18.4 Clamp the workpiece in the vise, by again raising the CLAMP
BAR and sliding it toward the workpiece until contact is made.
18.5 Drop the CLAMP BAR into a convenient slot in the clamp rack
(Item 46).
18.6 Tighten the vise by rotating the HANDWHEEL (Item 62)
clockwise until the workpiece is securely clamped in the vise.
Section 19: Positioning the Left Hand Blade Guide Assembly
Always position the left hand BLADE GUIDE assembly (Item 18) as
close to the MOVEABLE VISE (Item 49) as possible, as follows.
19.1 Loosen the BLADE GUIDE LOCK (Item 25) and slide the left
hand BLADE GUIDE CARRIAGE (Item 22) to the recommended
position.
19.2 Re-tighten the BLADE GUIDE LOCK before
cutting.
Section 20: Horizontal Operation
20.1 Raise the saw head so that the saw blade clears the stock
material.
20.2 Position the stock material in the vise and close the vise jaw tight
enough to hold the workpiece.
DO NOT REST THE BLADE ON THE WORKPIECEl
20.3 Re-check the position of the workpiece in the vise jaws.
20.4 When the position of the workpiece is cor rect, tighten the vise
firmly by hand, by turning the HANDWHEEL (Item 62)1
20.5 Position the left hand BLADE GUIDE
CARRIAGE and lock it in position by tightening the
BLADE GUIDE LOCK until it is moderately tight. DO
NOT OVERTIGHTEN!
20.6 Raise the saw head away from the work- piece as high as
possible.
20.7 Switch the saw “ON”.
20.8 Lower the sawhead by slowly turning the control knob on the
hydraulic DESCENT CYLINDER (Item 42) counterclockwise until
the saw head begins to descend allowing the saw blade to GENTLY
enter the material to be cut.
Lightly support the saw head by hand until a good introductory cut is
established.
After the blade has safely entered the material, it is no longer
necessary to support the frame by hand, since the natural feed of the
saw will complete the cut and the saw will switch “OFF”
automatically.
20.9 Repeat the foregoing opertions for each subsequent cut.
20.10 When through cutting remove the work- piece from the vise and
raise the saw head to its raised position.
It is best not to leave the saw head in the horizontal position, since in
this position the COUTERBAL ANCE SPRING (Item 56) is under
tension.
20.11 Clean saw and tidy up work area. See Sections 4 & 6.
Section 21: Re-adjusting the Counterbalance Spring
The COUNTERBALANCE SPRING (Item 56) assists the hydraulic
DESCENT CYLINDER in controlling the speed of the saw head
descent.
21 .1 To provide more counterbalance and a gentler rate of cutting as
well as longer blade life and smoother cuts, — TIGHTEN the
COUNTERBALANCE SPRING.
21.2 To provide less counterbalance and more vigorous rate of
cutting, — LOOSEN the COUNTER BALANCE SPRING.
Section 22: Raising the Saw Head to
4

Section 22: Raising the Saw Head to Vertical Position
22.1 Loosen the LOCKING BOLT (ITEM 35).
22.2 EXTEND THE VERTICAL SUPPORT LEG (Item 36)
about 6”.
22.3 Re-lock the locking bolt.
22.4 Lift the saw head so that it is perpendicular to the saw bed.
(Item 54).
22.5 With the saw head held upright, readust the position of the
VERTICAL SUPPORT LEG to touch the floor.
22.6 Re-lock the LOCKING BOLT.
22.7 Place the VERTICAL TABLE (Item 9) in place with about
1 ‘ clearance between it and the lower BEARING GUIDE
assembly. (Item 18).
Section 23: Vertical Operation
Although this machine will be used primarily as a cutoff saw,
— Notching, Slitting, and Contour Work will be done at times
with the saw head in the vertical position.
A VERTICAL TABLE (Item 9) is included with this bandsaw,
for this purpose.
For vertical operation, be sure that a fine-tooth saw blade is
installed in the saw, since in vertical operation the material to
be cut will most likely be of a light gauge.
23.1 Raise the saw head to its vertical position, (Section 21)
23.2 Install the VERTICAL TABLE.
23.3 Set the top BLADE GUIDE (Item 18) to a height above
the VERTICAL TABLE equal to 1/8” more than the thickness
of the stock material.
23.4 Proceed with cutting.
The same speed principles apply to vertical cutting as apply in
the case of horizontal cutting.
Feeding the material to be cut into the saw blade is obviously a
hand operation in vertical cutting, so
EXERCISE CAUTION AT ALL TIMES.
With practice, you will readily beome aware of the amount of
pressure that will be needed to achieve the best cutting
efficiency, (See Section 6).
Section 24: Switch Actuator Adjustment
Adjust the SWITCH ACTUATOR (Item 44) up or down so that
the ON-OFF SWITCH (Item 45) is turned “OFF” when the saw
has cut through the workpiece.
Section 25: Programming
To avoid costly, time consuming changeovers and re-
adjustments, it is wise to plan in advance the cuts
to be made, and do them all in the same set up.
Section 26: Important Notes
The BLADE GUIDE BEARING adjustments outlined in
Sections 12 and 13 are the most impor tant adjustments on
your saw. It is impossible to get satisfactory work from
your saw if the BLADE GUIDES are not properly
adjusted.
The BLADE GUIDES are adjusted and power tested with
several test cuts before leaving the factory to ensure
proper setting and the need for readjusting should rarely
occur when the saw is properly used.
However, if the BLADE GUIDES do get out of
adjustment, it is extremely important to re-adjust them at
once.
If improper adjustment is allowed, the blades will not cut
straight, and if the situation is not corrected, it will cause
serious blade damage.
Because BLADE GUIDE adjustment is a critical factor in
the performance of your saw, it is always best to try a new
blade to see of this will first correct poor cutting before
proceeding with any readjust ing.
If a blade becomes dull on one side sooner than on the
other, forexample, itwill begin cutting crooked.
A simple blade change will correct this problem whereas
the more difficult BLADE GUIDE adjust ment will not.
If a new blade does not correct the problem, check the
BLADE GUIDES for proper spacing.
For most efficient operation and maximum accu racy in
cutting, the BLADE GUIDE BEARINGS should just
touch the blade so that they will still turn freely.
Care should be taken to ensure that the welded blade area
is no thicker than the parent metal.
A minimum of three (3) teeth should be on the workpiece
at all times, for proper cutting, — if the teeth of the blade
are so far apart that they straddle the workpiece, severe
damage to the workpiece and to the blade can result.
CARE MUST BE EXERCISED TO KEEP THE
BLADE FROM RUBBING EXCESSIVELY ON THE
SHOULDER OF THE BLADE WHEELS AS THIS
WILL DAMAGE THE PULLEYS AND/OR BLADE.
