For your machine to produce accurate square cuts the Squaring Arm needs to be fixed at exactly 90° to the Main Column. to adjust the Squaring Arm first select a sheet of foam core or foam board (3-6mm) at least 60cm x 100cm (24” x 36”) in size. The larger the board the greater the accuracy.
1. Place the board on the machine vertically as shown and apply the clamp ensuring the bottom edge is in firm contact with the Squaring Arm.
2. Select the cutting blade on the rotating cutting head (see section 6). Cut into the top of the board to produce a cut approximately 3cm (1″) long. Disengage the cutter using the cutter release lever. Lower the cutter and make a similar cut at the bottom of the board by pressing the blade through the board about 3cm (1″) from the bottom edge of the board.
3. Unclamp and turn the board around and place it back in the SteelTrak but do not clamp it.
NOTE: For the test to work the board must be turned laterally (like a page in a book) not top to bottom.
Move the sliding head down and align the board so that the cutting blade enters the previous made cut at the bottom edge of the board. Apply the clamp. Release the blade..
4. Raise the sliding head and depress the blade so that it engages with the top
edge of the board, if the machine is square the blade will enter the same cut as made previously. if not refer to the following page to make the necessary adjustment.
Adjusting the Squareness
NOTE: Before making any adjustments carry out the squareness check as described on the previous steps.
It is assumed that the board used for the test is still clamped in the machine. From the test results determine if the last cut made in the top of the board is to the left or right of the previous cut, as shown above:
1. Slacken the two screws(1 + 4) joining the Squaring Arm to the two Legs.
2. Slacken the left hand nut (2) joining the Squaring Arm to the Main Body, make sure the right hand nut (3) is tight.
3. Release the clamp and position the board such that the blade is held in the cut on the bottom edge of the board, press down on the board to make sure it is in good contact with the Squaring Arm.
4. Turn the squaring adjustment knob (5) on the right hand Leg in the direction shown below dependant upon the position of the top two cuts.
If the second cut is to the right of the first cut turn the adjustment screw clockwise when viewed from underneath. If the second cut is to the left of the first cut turn the adjustment screw counterclockwise when viewed from underneath. The adjustment screw should be moved so that when the blade is moved to the top of the board it cuts between the two existing cuts, the plastic sightline fixed to the edge of the clamp gives an indication where the machine is going to cut.
5. Repeat the squareness check.
6. Tighten the screws (1,2, & 4) nut loosened in 1& 2 above.
