Locate the Air Valve on the back of the Board on the right side. Note the three connections from the Air Valve.

Take the Clamp Valve Plug (Grey cable with the Green Power Plug) and plug it into the Clamp Valve (the matching Green Plug on the top of the Gantry).

Take the Clear Air Line with the Red Connector from the Air Valve and Plug it into the Air Line with the Red Connector at the top of the Gantry by giving it a 1/4 turn onto the locking connector.

The top of the Straight Line Trimmer has an Air Line coming out of the back it, which connects to a Blue Connector/Shut Off Valve on a “Y” Connector.

Take the Black Air Line with the Red Connector from the Air Valve and Plug it into the Red Connector of the “Y” on the Straight Line Trimmer. Only one will fit.

NOTE: If you did not install the ST 500, this Black Air Line with the Red Connector would plug into the right side of the Air Regulator.

Plug in the other Air Line with the Red Connector of the “Y” into the right side of the Air Regulator.

Plug the Air Line coming off the Left side of the Air Regulator into your main air supply via 1/4” NPT female connector, or the quick disconnect, whichever type you purchased. Your air compressor should have at least 100 - 120 PSI. Shown below is the black threaded fitting connected to a 1/4” NPT female adaptor. It is suggested that Teflon tape be used on the threads of the black fitting to reduce possible air leakage.

Strap your Air Regulator, glass bowl down to the left large wall bracket or left stand side with cable ties provided in your Tool Kit, making sure not to crimp any of the Air Lines.

Turn on the Air.

Continue to Calibration and Alignment of the Straight Line Trimmer.

WARNING: The Air Regulator comes factory-set. Do not make any adjustments to it.

Do not press down on the Trimmer Handle while moving in an upwards direction, or you will break the Blade.

Place at least one piece of matboard larger than the mat being trimmed behind the Straight Line Trimmer to avoid cutting into the Board.

Place the matboard to be cut underneath the Straight Line Trimmer; use the handy ruler for placement.

Flip the clamp switch upwards to lock the matboard down.

Raise the handle and pull upwards to bring the cutting assembly to a position above the mat to be cut.

Press down on the handle and pull downwards.

Flip the clamp switch downwards to unlock the matboard, and remove the matboard.

Place a piece of matboard at the 10” mark, and using the Trimmer, trim it. Measure the width of the matboard. If it does not measure 10” across the top and across the bottom, the Trimmer needs to be calibrated.

Start with the bottom. Loosen the bottom Locking Knob by turning it Clockwise.

Using a 7/16” Open-Ended Wrench, loosen the Locking Nut.

Using a 3/16” Allen Wrench, turn the Alignment Adjustment Screw Clockwise to move the Trimmer to the Right; turn it Counter-Clockwise to move the Trimmer to the left. When moving to the Left, you will need to push the Trimmer to the Left so that the Alignment Adjustment Screw stays on contact with the rail.

Tighten the bottom Locking Knob by turning it Counter-Clockwise.

Cut the mat again... remember we are looking at the bottom of the mat. When the bottom of the matboard cuts the correct width, retighten the Locking Nut to keep the Alignment Adjustment Screw from moving.

Trim a tall piece of matboard at 10” and measure across the top and across the bottom. If it does not measure 10” across the top and across the bottom, continue.

Loosen the top locking knob by turning it Counter-Clockwise.

Using a 7/16” Open-Ended Wrench, loosen the Locking Nut.

Turn the Alignment Adjustment Screw Clockwise to move the Trimmer to the Right; turn it Counter-Clockwise to move the Trimmer to the Left. When moving to the Left, you will need to push the Trimmer to the Left so that the Alignment Adjustment Screw stays on contact with the rail.

Tighten the top locking knob by turning it Clockwise.

Cut the mat again, and readjust if necessary. When the top of the matboard cuts the correct width, retighten the Locking Nut to keep the Alignment Adjustment Screw from moving.
