Unpacking Cut the strapping, open the carton and remove all parts from the packaging Assembly Building the stand This is most easily accomplished on a bench or table Leave all nuts and bolts finger tight until you have finished assembling this stand. Start with the long top rail and bolt it inside one leg. Add a short rail, making sure that it sits above the long rail as viewed from the underside, i.e. as you have it on the bench. Continue until all four legs and rails are joined.
Fitting the Saw to the Stand If you have someone to help you, the easiest way to join the saw and the stand is to lift the saw and lower it into place. Secure it with the four countersunk setscrews, washers and nuts provided. Fixing bolts Alternately; If you have nobody to help, lower the saw onto its back and bolt the stand to it. After tightening the fixing bolts, lift the top of the saw and pivot it on the rear feet until it is upright and all four feet are on the ground.
Screw the longest of the 6 mm hex headed bolts into its hole as shown. Place the table in position on the trunnion and fix it with the four remaining 6 mm bolts. Check to see if the blade is centred in the slot. You will probably find that it is offset to one side or the other. This pointer is adjustable if the setscrew is loosened. You may need to make a small adjustment after the table is set perpendicular to the blade.
Screw the four hex, wing bolts and washers into the tapped holes on the underside of the table and slide the rip fence carrier on to them. Adjust the two hex headed bolts so that the carrier fits snugly to the table with no gap between its upper edge and the table. If you do not keep the carrier tight to the table the rip fence will not be perpendicular to it.
Screw in and lock the push stick hanger. Hang the push stick on it and remember that this is one of the world’s best finger preservers! Locate the tension adjustment knob and using a suitable tool, remove the cap. Be careful not to lose the nut which is inside. Place it over the spindle sticking out of the top of the saw, screw on the nut and lock the knob between the two nuts. Replace the cap.
Fit the control handle to the spindle protruding from the side of the saw. Rotate the handle, so that the grubscrew tightens onto the flat side on the spindle. Tighten the grubscrew securely. Apply a little tension to the blade and use a set square to position the table at right angles to it. Lock it in position and if necessary, adjust the level stop screw and the pointer so that it aligns with the zero as shown earlier. Setting up your saw Quick blade tensioner (shown in tight position).
After ensuring that the quick tension lever is set in the tensioned position, adjust the blade tension with the hand wheel on top of the upper housing. ‘Pluck’ the back of the blade, as you would the string of a double bass, at this point. As the blade tension is increased, the pitch of the sound will rise. Stop increasing the tension as soon as the sound starts to become dull.
Release the belt tension by turning the tension control handle on the front of the lower housing. Move the belt from the larger pulley to the smaller one and then from the smaller to the larger on the other pair. Always have the drive belt on one large and one small pulley. This bandsaw is equipped with a cross cut/mitre fence which can be fitted as shown. The fence is equipped with adjustable stops for 45° and 90° cuts. The rip fence is reversible and may be used on either side of the blade.
Lower the blade guard Remove the rip fence carrier Slide the blade off upper and lower wheels, bringing it out of the machine via the slots in the rear frame and the blade guard. Reverse these steps to fit the new blade. Ensure that the teeth are at the front and pointing down. Position the blade between the guide bearings and pins. Tension and adjust the tracking as done during the initial set up. Check and adjust, if necessary, the position of the bearings and the guide pins.
