ASSEMBLY & SETUP INSTRUCTIONS
BEFORE OPERATING BANDSAW
Assembling Stand, Wheel Set and Mounting Bandsaw (Fig.3)
1) Assemble the stand legs (A & E) Fig.3 and the 4 horizontal bars (B) together using 8 carriage bolts,8 washers and 8 hex. nuts.
2) Once the stand legs and horizontal bars are assembled, assemble the cross braces (C) on top of each end of the stand using 8 carriage bolts, 8 washers and 8 hex. nuts.
3) The next step is to assemble the wheels set (D) to the motor side of the stand legs (E). Insert the wheel shaft through the holes in both stand legs (E), place a large washer, a wheel, another large washer at each end of the wheel shaft secure both wheels in place with cotter pins.
4) Turn the stand assembly upside down and screw 2 rubber feet (F) into the stand legs (A).
5) Place stand back to upright position and place bandsaw on top of the stand, place the motor end of the bandsaw on the same side you installed the wheel set. Do not try to lift the machine by yourself, risk of back injury! It is recommended to get another person to help you or to use a chain hoist if available. Secure the bandsaw to the stand as using 6 hex. bolts, 12 washers and 6 hex. nuts.
Releasing Stop Pin
This bandsaw comes with a head stop pin (A) Fig.4 which allows you to lock and unlock the head, 2 different positions are available as shown. The head stop pin can be found at the rear of the bandsaw and should always be released before any cutting operation.
Setting Height of Feed Stop Bolt
Now the head stop bolt (A) Fig.5 and hex. nut (B) must be adjusted. This feed stop bolt will determine how low the head will go (normally below the table surface). Adjust the bolt height so that the blade teeth are just below the table surface when the cut is complete. Make sure to retighten the hex. nut once the adjustment has been made.
Assembly and Installation of the Work Stop
The work stop assembly gets assembled to the front of the table and is usually used for repetitious cuts of the same length. To assemble the work stop;
1) Slide the work stop (A) Fig.6 onto the work stop shaft (B) and fix it into place by tightening the work stop set screw (C).
2) Insert the work stop shaft into the side of the table as shown in Fig.6 and fix it into place by tightening the top table set screw (D).
ASSEMBLY & SETUP INSTRUCTIONS
BEFORE OPERATING BANDSAW
Installation of the Belt and Pulley Cover, Belt and Tensioning Belt
To install the belt and pulley cover;
1) Place the belt and pulley cover fixing plate (A) Fig.7 around the pulleys as shown in Fig.7 and fix it into place with 2 hex. bolts (B).
This bandsaw comes with 3 blade speeds, the blade speed is determined by the position of the belt on both pulleys. See chart below for belt position and resulting blade speed.
To install the belt around the pulleys;
1) First step is to unscrew the belt tension knob (A) Fig.8 in order to bring the motor assembly/motor pulley (B) Fig.9 closer to the drive pulley (C) Fig.9.
2) Then slide the belt (A) Fig.9 around the appropriate pulleys that will give you the required blade speed, see chart above.
3) Finally, tighten the belt tension knob (A) Fig.8 to tension the belt. The proper belt tension is achieved when the belt has a 1/2” deflection when pressed in the center.
4) Close belt cover and lock it closed with tapping screw and washer.
Adjusting Toggle Switch Auto Shut-off Plate
The auto shut-off plate must be adjusted, so the bandsaw shuts off automatically when a cut is complete. To adjust the auto shut-off plate;
1) With the bandsaw disconnected from the power source, lift the head and lock it into place and then place the toggle switch (A) Fig.10 to the “On” position.
2) Lower the head slowly to see if the auto shut-off plate (B) will push the toggle switch down to the “Off” position.
3) If the auto shut-off plate does not push the toggle switch all the way to the “Off” position, loosen auto shut-off plate bolt (C) and lower plate until it pushes the toggle switch all the way to the “Off” position.
4) Retighten the auto shut-off plate bolt.
SETUP & OPERATION INSTRUCTIONS
BEFORE OPERATING BANDSAW
Adjusting Vise Angle
To adjust the angle of the vise;
1) Loosen hex. bolt (A) Fig.11 and slide the vise (B) to the desired angle. Use the scale (C) as a guide to set your angle.
2) Retighten hex. bolt (A) once you have obtained the desired angle.
3) Loosen hex. bolt (D) on the opposite vise jaw so that the jaw can float and match the angle of the workpiece once you tighten the vise against the workpiece by turning vise handwheel clockwise.
Squaring Blade to Table
Squaring the blade to the table will improve your cutting results and also extend the life of your blade. To square blade to table;
1) Lower the head all the way until it comes in contact with the head stop bolt.
2) Place a square (A) Fig.12 on the table and against the edge of the blade, checking at a few different points between the blade guides.
3) If an adjustment is needed, loosen hex. bolt (B) and rotate the blade guide seat
(C) until the blade is perpendicular to the table, then retighten hex. bolt.
Adjusting Blade Guides
The blade guides side bearings support and twist the blade straight so the blade will enter the workpiece perpedicular to the table surface. The blade guide support bearings prevent blade twist by stopping the blade from being pushed back during a cut. Both adjustments are important for correct saw operation.
Keep in mind that this adjustment must be done to both the right and left blade guides, to adjust the blade guides;
1) Adjust the blade guide housing (A) Fig.13 by loosening the housing hex. bolt
(B) so the support bearing rests against the rear of the blade.
2) Loosen the outer side bearing eccentric hex. nut (C) and rotate the eccentric bearing shaft until both bearings have a bearing-to-blade clearance of 0.000” to 0.001”. Do not pinch the blade and remember that the blade must be perpendicular to the table.
3) Retighten the outer side bearing eccentric hex. nut.
4) Before every operation, unlock the right side bearing guide lock knob (D) and slide the left side bearing guide assembly (E) as close to the workpiece so the blade is supported and will not twist during the cut. Retighten the left side bearing guide lock knob.
Setting Up for Vertical Cutting
This bandsaw is capable of horizontal and vertical cutting operations. Vertical cutting operations require an additional steel table to be mounted to the right side blade guide assembly. To install vertical table;
1) Position the head to its most upright vertical position.
2) Remove the blade guide cover (A) Fig.14 by removing the 2 countersunk screws (B).
3) Install the vertical table and secure into place using the same 2 countersunk screws removed previously.
4) Install support bracket (A) Fig.15 below the vertical table using the bolt (B) already in the casting and a countersunk screw and hex. nut (C) Fig.15.
5) Place a square on the table and against the blade and adjust the support bracket height to quare the table with the blade.
SETUP & OPERATION INSTRUCTIONS,
1) A 14 tooth per inch, general-use blade is furnished with this metal cutting band saw.
2) The choice of blade pitch is governed by the thickness of the work to be cut.
3) The thinner the workpiece, the more teeth advised.
4) If the teeth of the blade are too far apart, it can result in severe damage to the workpiece and to the blade.
Suggested Blade Speeds for Material to Cut
When using your bandsaw, always change the blade speed to best suit the material to cut. The material cutting chart Fig.16 suggests settings for several materials.
Tool, stainless or alloy steel, bearingbronzes.
Belt groove used
Motor pulley Drive pulley
Mild steel, hard brass or bronze.
120 Medium Medium
Soft brass, aluminum, other light metals.
The feed rate of the blade into the workpiece is controlled by the spring tension.
To set the feed rate;
Slower Feed Rate- Twist the feed rate adjustment handle (A) Fig.17 clockwise to add tension to the spring.
Faster Feed Rate- Twist the feed rate adjustment handle (A) Fig.17 counter-clockwise to remove tension from the spring.
Blades should be changed when they become dull or damaged or when you are cutting materials that require a blade of a certain type or a specific number of teeth. To replace/change blade;
1) Make sure the bandsaw is disconnected from the power source.
2) Lift the cutting head to its most vertical position.
3) Remove the blade guard lock knob (A) Fig.18 and the 2 round head screws
(B) which hold the blade guard (C) in place and remove blade guard.
4) Loosen the blade guides, then loosen the blade tension knob (D) counterclockwise and slip the blade off the wheels.
5) Install the new blade through both blade guides and around the bottom wheel.
Make sure the blade teeth point downwards and that the back of the blade rests against the shoulder of the bottom blade wheel.
6) Hold the blade around the bottom wheel with one hand and slip it around the top wheel with the other hand, keeping the blade between the blade guides.
7) Once the blade is around both wheels, position the back of the blade against the shoulders of the wheels.
8) Tighten the blade tension knob enough to tension the blade so the blade does not fall off the wheels during start-up. Spin the wheels by hand until the blade resumes the previous tracking. If the blade drifts away from the shoulder of the wheels, adjust the tracking of the blade, see following instructions.
ADJUSTING BLADE &
Adjusting the Tracking of the Blade
The blade tracking has been set at the factory and will rarely need to be adjusted if the bandsaw is used correctly. To adjust the tracking of the blade;
1) Turn the blade tension knob (A) Fig.19 counterclockwise so that the blade loosens a little.
2) Loosen but do not remove the wheel tilting mechanism hex. bolt (B).
3) Adjust the tracking of the blade by adjusting the set screw (C). Tightening this set screw will move the blade closer to the shoulder of the wheel. Loosening this set screw will move the blade away from the wheel shoulder.
4) Tension the blade to the appropriate tension. Turn the wheel by hand and observe the blade tracking. If the blade tracks along the shoulder without rubbing, the blade is tracking properly. If the blade drifts away from the wheel shoulder, repeat step 3.
5) Once the blade is tracking properly, replace the blade guard and adjust the blade guides.
It is easier to keep this bandsaw in good condition or at best performance by means of maintaining it than having to remedy it after it is out of order. Keep work area clean; release vise, release blade tension to prolong blade life, disconnect from power source, remove chips and dust away and follow instructions for lubrication or coating rust proof oil before leaving. On a monthly basis, lubricate guide bearings. Also check electric cord, plug, switches to make sure they are operating correctly.
Your machine has been coated heavily with grease to protect it in shipping. This coating should be completely removed before operating. Commercial degreaser, kerosene or similar solvent may be used to remove the grease from the machine, but avoid getting solvent on the belts or other rubber or plastic parts.
1) Be sure to clean the bandsaw after operation. Coat it with rust-proof oil.
2) Use SAE-30 oil to lubricate the components.
3) Lubricate the vise lead screw as needed.
4) The drive gears in the gear box soak in an oil bath, they will not require a lubricant change more than once a year, unless leakage or overheating occur.
When replacing the gear box oil, use SAE 80W90 differential oil.
