If you purchased the KC-227-2, 220V model, follow the instructions and warnings below.
CURRENT CARRYING PRONGS
YOUR BANDSAW MUST BE CONNECTED TO A 220V, 20 AMP. BRANCH CIRCUIT. Your bandsaw is ready to operate on a 220V, 20amp. circuit. This bandsaw is intended for use on a circuit that has an outlet and a plug configuration which looks like the one illustrated in Fig.1.
This bandsaw must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for electric current, to reduce the risk of electric shock. This bandsaw is equipped with a cord having an equipment-grounding conductor and grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
ARE NOT DO NOT USE A TWO-PRONG ADAPTOR FOR THEY IN ACCORDANCE WITH LOCAL ORDINANCES. NEVER USE IN CANADA.
CODES AND A 220V plug is not supplied with the bandsaw and must be purchased at your local hardware store. The 220V plug must be a CSA listed plug suitable for 220V operation. This plug is illustrated in Fig.1. Contact your authorized service center or qualified electrician to install the plug.
LENGTH OF CONDUCTOR 0-25 FEET 26-50 FEET 51-100 FEET
WIRE SIZES REQUIRED (AMERICAN WIRE GAUGE) 220V LINES NO.14
WARNING! IT IS NOT RECOMMENDED TO USE AN EXTENSION CORD, BUT IF IT IS NECESSARY, READ THE FOLLOWING.
The use of any extension cord will cause some loss of power. Use the chart Fig.2 to determine the minimum wire size (A.W.G-American Wire Gauge) extension cord required. Use only 3-wire extension cords which have 3-prong grounding type plugs and 3-hole receptacles which accept the tool’s plug. For circuits that are further away from the electrical circuit box, the wire size must be increased proportionately in order to deliver ample voltage to the motor. The wire gauge number decreases the longer the extension cord needs to be.
ADJUSTING DOWNWARD TRAVEL OF SAW ARM
When the saw arm is in the extreme downward position, the teeth of the blade should be 1/16” below the table surface. If an adjustment is necessary, loosen the hex. nut (A) Fig. 3, and turn the rubber stop (B) in or out until the correct adjustment is made. Then retighten hex. nut (A).
CHANGING SPEEDS AND ADJUSTING V-BELT TENSION
Your bandsaw is provided with a range of four speeds: 114, 196, 288, and 377 feet per minute. To change speeds, proceed as follows: 1. Disconnect the machine from the power source.
2. Release tension on the V-belt by turning the tension lock ring (A) Fig. 4 counterclockwise, and let the motor swing downwards.
3. Open belt and pulley cover (A) Fig. 5.
4. Shift the V-belt (B) Fig. 5, to the desired grooves on the pulleys. When the belt is on the largest step of the motor pulley (C) and the smallest step of the gear pulley (D) the speed will be 377 feet per minute. When the V-belt is on the smallest step of the motor pulley and the largest step of the gear pulley the speed will be 114 feet per minute. See chart below for all speeds and V-belt positioning.
Blade Speed FPM (M/min.) (Belt Positioning) 114(35) Motor 196(60) 288(88) 377(115)
5. Adjust the V-belt tension by lifting the motor until there is approximately 1/2” deflection of the belt at the center span of the pulleys using light finger pressure. Then tighten tension lock ring (A) Fig. 4 and close V-belt and pulley cover.
ADJUSTING BLADE TENSION
To tension the blade, turn the blade tension handles (A) Fig. 6, clockwise. A blade tension pressure gauge (B) located above the tension handles is graduated to indicate blade tension from 0-70,000 pounds per square inch.
Carbon blades (similar to the one supplied with this bandsaw) should be tensioned at 20,000 PSI. For bi-metal blades, the blade should be tensioned between 25,000-29,000 PSI. Do not exceed 21,000 PSI if using a 3/4” blade and 29,000 PSI using a 1” blade. Always release blade tension at the end of each work day to prolong blade life.
FIGURE 3 FIGURE 4 FIGURE 5 FIGURE 6
ADJUSTING BLADE TRACKING
Make sure the blade is tensioned correctly before checking or adjusting blade tracking.
The blade is tracking properly when the back of the blade is just lightly touching the wheel flanges of both wheels while the machine is running. If the blade is not touching the wheel flanges, loosen hex. bolt (A) Fig.7, then tighten or loosen the special hollow hex. bolt (B) until the blade tracks properly.
ADJUSTING BLADE GUIDE SUPPORT ARM
The blade guide support arm (A) Fig. 8, should be set as close to the workpiece as possible. To move the support arm, first loosen clamp knob (B).
Move the support arm (A) into relationship with the workpiece. When you are sure the support arm will not interfere with the workpiece, tighten clamp knob (B). Although the second blade guide support arm (C) works in the same manner, its complete right position should not be changed.
FIGURE 7 FIGURE 8
ADJUSTING CUTTING PRESSURE OF SAW ARM
The cutting pressure of the saw arm has been set at the factory and should not need further adjustment.
If adjustment should ever become necessary, lower the saw arm to the horizontal (down) position. Loosen hex. nut (A) Fig. 9 to increase the cutting pressure or tighten the hex. nut to decrease the cutting pressure.
OPERATING AND ADJUSTING TRU-LOCK VISE SYSTEM
The workpiece gets placed between the vise jaws with the amount to be cut-off extending out past the blade. Your bandsaw is equipped with a “TRU-LOCK TM ” cam locking lever and a “quick action” vise jaw which allows you to quick position and lock the vise jaw against your workpiece. To operate these mechanisms, proceed as follows: 1) Put your workpiece on the table and raise the cutting arm 2” above the workpiece. Turn the hydraulic cylinder shut-off dial to the “Off” position to maintain the cutting arm 2” above the workpiece.
2) Position the cam lock lever (A) Fig.10 in the upwards position, turn the handwheel (B) a 1/4 turn at a time counterclockwise until you are able to move the vise jaw (B). Once the vise jaw is in position close to the workpiece, turn the handwheel clockwise and lower the cam lock lever (A) to its down position as shown in Fig.10 to firmly hold your workpiece.
3) To loosen the workpiece from the vise, hold the workpiece and lift the cam lock lever (A) to its upwards position (completely opened) and remove workpiece.
When you need to cut workpieces of the same dimension many times, just raise the cam lock lever (A) to loosen and adjust workpiece position. Then push it downwards again to retighten.
FIGURE 9 FIGURE 10
OPERATING AND ADJUSTING TRU-LOCK VISE SYSTEM cont......
The vise can be adjusted to cut any angle from a straight 90 degree cut-off to 45 degree angle. To adjust the angle of both vise jaws, first loosen the spring loaded clamp handle (A) Fig.11 on the right side vise jaw (B) and position it to the desired angle and retighten the spring loaded handle.
Then loosen the hex. shaft (D) Fig.10 on the left side vise jaw (C) with a 19mm open ended wrench. Place your workpiece on the table and tighten the vise jaw against it and tighten the hex. shaft to secure angle. The right side vise jaw comes with positive stops to instantly position the vise jaw at 90 or 45 degrees. To check and adjust the positive stops, proceed as follows: 1. To check the 45 degree positive stop, pivot the right side vise jaw all the way to the left, and lock the spring loaded clamp handle.
2. Place one end of a 45 degree square against the vise jaw and the other end against the blade and check to see if the vise jaw is 45 degrees to the blade.
3. If an adjustment is necessary, loosen clamp handle and then loosen locking set screw (A) Fig.13 and turn adjusting set screw (B) until the vise jaw is at 45 degrees to the blade. Note: The end of set screw (B) should contact the stud of clamp handle when vise jaw is 45 degrees to the blade. Then tighten set screw (A).
4. To check the 90 degree positive stop, pivot the right side vise jaw all the way to right and lock spring loaded clamp handle.
5. Place one end of a 90 degree square against the vise jaw and the other end against the blade and check to see if the vise jaw is 90 degrees to the blade. 6. If an adjustment is necessary, loosen clamp handle and then loosen locking set screw (C) Fig.13 and turn adjusting set screw (D) until the vise jaw is 90 degrees to the blade. Note: Turn set screw (D) from the opposite end, through the face of the vise jaw. The end of set screw (D) should contact stud of clamp handle when vise jaw is 90 drgrees to the blade. Then tighten set screw (C).
ADJUSTING STOCK ADVANCE STOP
The stock advance stop Fig.14 is used mainly when more than one piece of work is to be cut to the same length. Simply position the stop bolt (A) to the desired distance away from the blade. The stop bracket (B) may be repositioned up or down by loosening lock knob (C), the stop arm (D) can also be adjusted in or out on the stop rod (E) by loosening the stop arm set screw (not shown- it is under the stop arm D). Fine adjustment to the stop can be made by loosening hex. nut (F) and turning stop bolt (A).
FIGURE 11 FIGURE 12 FIGURE 13 FIGURE 14
ADJUSTING BLADE BACK-UP BEARINGS, BLADE GUIDE ROLLER BEARINGS AND CARBIDE BLADE GUIDES
Before making the following adjustments make sure the blade is tensioned and tracking properly: 1. The back of the blade should ride against the back-up bearing (A) Fig.15.
To adjust, loosen cap screw (A) Fig.16 and tighten the set screw (B) Fig.15
to move the entire blade guide assembly down until the back-up bearing lightly touches the back of the blade.
2. The saw blade should also ride between and lightly touch the two blade guide roller bearings (C & D) Fig.15. Both bearings are mounted on eccentric shafts. Normally it is longer bearing shaft assembly (C) which is adjusted to suit blade thickness, this is done by loosening set screw (E) and turning shaft (F).
3. The carbide blade guides (G) Fig.15, should also be adjusted so they lightly touch the blade, this is done by loosening cap screws (H).
4. The blade guide roller bearings, carbide blade guides and back-up bearing on holder (B) Fig.16 should be adjusted in the same manner.
SQUARING THE BLADE TO THE TABLE
Before making the following adjustments make sure the blade is tensioned and tracking properly: If you find that the bandsaw is not cutting square, you may need to adjust the blade square with the table.
1. Examine the workpiece and try to determine which way the blade is twisting or place a 90 degree square on the table and against the blade as shown in Fig.17.
2. Check for gaps along the blade, in order to bring the blade into proper squareness with the table, it will be necessary to adjust the blade guide block assemblies. 3. To make this adjustment, first loosen the set screws (A) Fig.18 (on both blade guide block assemblies).
4. Then adjust set screws (B & C) to pivot the blade guide block assembly. To pivot the blade guide block assembly inwards (towards the bandsaw), tighten the 2 lower set screws (C). For outwards travel, tighten the 2 upper set screws (B).
5. Adjust these set screws in pairs and adjust them until the blade is perfectly square with the table. Don’t forget to retighten the 2 set screws (A) Fig.18
FIGURE 15 FIGURE 16 FIGURE 17 FIGURE 18
OPERATING CONTROLS CONTROL PANEL
1. Raise the saw frame to the up position.
2. The machine is started by pushing the start button (A) Fig.19. The “Power On” light (C) will turn on. The bandsaw will continue to run until the saw arm is in the down position at the end of the cut, or when the stop button (B) is pushed.
3. The down feed speed can be ajusted by setting the feed rate knob (D). If you need to quickly stop the down feed of the saw arm, turn the hydraulic shut-off valve knob (F) to the right (red symbol) to stop. To restart the down feed at the identical feed rate set before, turn the hydraulic shut-off valve knob (F) to the left (green symbol).
4. To begin the coolant flow of the coolant pump during cutting operations, turn the coolant knob (E) to the left, to stop the coolant flow turn the coolant knob to the right.
AUTOMATIC SHUT-OFF LIMIT SWITCH
1. An automatic shut-off limit switch is provided to stop the motor when the cut is completed. The limit switch (A) Fig.20 comes into contact the top of the stop bolt (B) shutting off the motor and coolant pump.
2. If the motor stops before the cut is completed, or continues to run after the cut is completed, the height of the stop bolt (B) can be adjusted to make it contact earlier or later. Loosen the hex. nut (C), adjust the height of the stop bolt up or down, and make a test. Once this adjustment is done, retighten the stop bolt hex. nut.
The bandsaw has a built-in coolant system, using coolant during operations will extend the life of your blades by lowering the temperature of the blade and workpiece during cuts.
Setting up the coolant system: Remove the rear panel of the cabinet base to access the coolant reservoir (A) Fig.21. Fill the reservoir with your chosen cutting fluid solution (see your nearest car parts or industrial machinery dealer for more information) through the opening (B). Do not fill above the “H” (high) mark (H) on the reservoir, fill again with coolant fluid solution before the level gets below the “L” (low) mark (L), or else you could damage the coolant pump. Reposition the rear panel of the cabinet base.
The rate of coolant flow is controlled by 2 independently operated stop valve levers (A -one of two) Fig.22, which direct the coolant onto the blade at 2 different areas under each control arm. When doing small cutting operations, only use one to direct collant flow to the workpiece. If additional coolant flow is required to cover a larger cutting area, turn on the second stop valve lever and position the control arms as close to the workpiece as possible.
Clean the cabinet chip screen so coolant can recycle back to the coolant reservoir. If the coolant level gets below the “L” (low) mark (L) Fig.21, you risk damaging the coolant pump.
BIOLOGICAL AND POISON HAZARD!
During storage some fluids grow dangerous microbes, or due to the collection of toxic metal chips in the fluid, the fluid can become a potent and extremely poisonous solution to humans and animals. Use proper personal protection equipment when handling cutting fluid and follow provincial laws and fluid manufacturer requirements to properly dispose of cutting fluid.
FIGURE 19 FIGURE 20 FIGURE 21 FIGURE 22
REMOVING AND INSTALLING A BLADE
Blades should be changed when they become dull, damaged or when you want to cut materials which require a blade of a certain type or tooth count. It is recommended to wear gloves during the removal and installation of a blade.
1. Disconnect the machine from power source.
2. Raise the saw frame about 6” and turn the hydraulic shut-off valve knob (F) Fig.23 to the right (red symbol) to keep the saw frame in this position.
3. Open both wheel covers (A) Fig.23 and clean the debris out of the machine.
4. Release blade tension by turning the blade tension levers counterclockwise.
5. Loosen two lock knobs (B) and remove blade guard (C).
6. Remove two lock knobs (D) and remove top blade guard (E).
7. Remove the blade (G) from both wheels and out of each blade guide.
8. Before installing a new blade, make sure the teeth are pointing in the right direction (towards the workpiece). If necessary, turn the blade inside out.
9. Place the new blade on the wheels and follow the blade guide, tensioning and tracking adjustments in this manual and reposition all blade guard removed previously.
PROPER BLADE TOOTH SELECTION
You need to consider: 1.
THE WIDTH OF CUT.
That is, the distance in the cut that each tooth must travel from the point it enters the workpiece until it leaves the workpiece.
THE SHAPE OF THE WORKPIECE - Squares, rectangles, flats
. (Solid square symbol) EX.: 6” (150mm) Square, use a 2/3 Vari-Tooth.
- Round solids
(Solid circle symbol). EX.: 4” (100mm) round, use a 3/4 Vari-Tooth.
Tubing, pipe, structurals
( symbols). Determine the average width of cut by dividing the area of the workpiece by the distance the saw blade must travel to finish the cut. EX.: 15” (380mm), use a 2/3 Vari-Tooth.
BLADE SPEEDS VERSUS TYPE OF MATERIAL
FIGURE 24 FIGURE 25
SETTING UP THE MACHINE FOR OPERATION
1. Depending on the material to cut, select and install the proper blade and set the proper blade speed.
2. Make sure the blade tension is adjusted and that the blade is tracking properly.
3. Raise the saw frame and close the feed on/off knob (A) Fig.26.
4. Place workpiece between the vise jaws. Adjust the stock for the desired length of cut, tighten the vise handwheel (B) and lower the cam lock lever (C) to firmly secure workpiece.
5. Make sure the blade guide control arm (D) is adjusted as close as possible to the workpiece.
6. Turn the coolant selector (E) to the “On” position, then turn machine on by pressing the “On” button (F). Note: If the “Emergency stop/off” button (G) is pressed, it needs to be twisted until it pops out or the bandsaw will not start. Just in case, keep your finger near the “Emergency stop/off” button at all times during the operation. The bandsaw should run smoothly with little or no vibration. 7. Adjust the coolant flow using one or both coolant valves (H & I) above the control arms.
8. Turn the feed rate control knob (J) counterclockwise until the saw blade begins to lower, see the feed rate guideline section below as reference.
9. Proceed to cut through the workpiece. The motor and coolant pump will shut off upon completion of the cut.
FEED RATE GUIDELINES
When the feed rate control knob is turned clockwise as far as it will go, the saw frame will not move down, but can be raised to the up position.
Turning the feed rate control knob counterclockiwise, the flow of oil from the cylinder is regulated and determines the speed at which the saw frame will lower and the blade will feed through the work. Too many factors are involved to make tabulated data practical on feed rates. As a general rule, an even downward pressure without forcing the blade gives best results. Burned chips indicate excessive feed, which causes the teeth to break off as the blade overheats. The ideal feed rate is indicated by chips that have a free curl and this will give the fastest cutting time and longest blade life.
1. Let the blade reach full speed before engaging the workpiece. 2. Never start a cut with the blade in contact with the workpiece, and do not start a cut on a sharp edge. 3. Chips should be curled and silvery. If the chips are thin and powder like, increase your feed rate. 4. Burned chips indicate a need to reduce your blade speed. 5. Wait until the blade has completely stopped before removing the workpiece from the vise, and avoid touching the cut end—it could be very hot!
6. Use coolant when possible to increase blade life.
REGULAR MAINTENANCE Blade and blade guides
: Place a few drops of light machine oil on the blade and the blade guides daily, especially when cutting cast iron, coolant fluid is not recommended on cast iron.
Table and machined surfaces
: Table and machined surfaces should be kept rust-free with regular applications of paste wax.
: Place a few drops of light machine oil on the vise leadscrew weekly.
REPLACING GEAR BOX OIL DO NOT
operate saw without checking gear box oil level! Operating without sufficient oil will damage the machine!
The gear box should be drained and refilled after the first 50 hours of use and thereafter every 5 months, with Mobil Synthetic Gear Oil, SHC-636, ISO 680.
To change gear box oil, proceed as follows: 1. Run the machine for 10 minutes to warm up the gear box.
2. Disconnect the machine from the power source.
3. Raise the saw arm to its maximum position and close the feed rate control knob.
4. Drain the gear box by removing drain bolt (A) Fig.27.
5. Replace drain bolt (A) and lower the saw arm to its lowest position.
6. Remove oil cap (B) and fill the gear box with oil through the oil cap opening until the oil level reaches the halfway mark (red dot) in the oil sight glass (C) Reposition the oil cap (B).
