Straight Line Trimmer: ST 500: Straight Line Trimmer Manual

NOTE: A Blade has been installed, so take care when handling the Straight Line Trimmer.

Look at the backside of the Trimmer and locate the T-Nut on the glides. Make sure that the T-Nut lines up with the glide on both the upper and lower sections of the Trimmer.

Holding the Straight Line Trimmer steady (a second person helps here), carefully slide the Trimmer onto the channels on the right side of the Board, making sure that the T-Nuts slide into the channel of both the upper and lower rails.

Move the Straight Line Trimmer to the right until it stops.

Slowly tighten the bottom locking knob COUNTER-CLOCKWISE until it is snug.

Slowly tighten the top locking knob CLOCKWISE until it is snug. You will calibrate it after the air lines are hooked up.

Look at the Serial Number of your CMC Board, which is located on a label in the lower left corner of the Board. If the Serial Number begins with BA-02, go to Attaching Air Lines BA-02-#####. Otherwise, follow the directions for Attaching Air Lines BA-03-######.

Go back and make sure that the Air Lines on the back of the Board are not pinched between the Board and the Stand. If you have not already done so, reattach the Air Lines on the inside of the Stand Arms to ensure maximum air flow.

Connect the Blue Connector from the top of the ST 500 to the Blue Connector/Shut Off Valve of the “Y” Connector.

Connect Red Connector from the top of the Gantry to the Red Connector of “Y” Connector; only one side will fit.

Plug in the Red Air Line Connector from the bottom 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. 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.

Connect Blue Connector from the top of the Gantry to the Blue Connector on the back of the Board.

Turn on the Air.

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

Continue to Calibration and Alignment of the Straight Line Trimmer.

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.

Lift up the Handle and pull the Blade Holder straight out.

Gently pull the Blade Cartridge away from the Holder; note that it is inserted face-down against the Holder.

Carefully remove the Blade and replace with a new Blade.

Turn the Blade Cartridge over and re-insert into the Blade Holder.

Slide the Blade Holder into the Trimmer; note that there is a ridged edge and can only be inserted one way.

Lift up the Handle.

Using 1/8” Allen Wrench, turn the Allen Screw Clockwise to increase the Blade Depth, Counter-Clockwise to decrease it.

You can also lock the Trimmer into a position by turning the Trimmer Lock Clockwise. You can set the Trimmer Lock Screw tighter so that the Cutting Head stays where ever you leave it. Turn the Trimmer Lock Counter-Clockwise to make it loose again.

Do not use the Wizard to cut anything wider than 53” from the left edge of the matboard while the Straight Line Trimmer is installed, or you will risk having the Head collide with the Straight Line Trimmer. This includes the outside cut. If you need to cut something that is larger than 53” from the left edge of the matboard, you will need to temporarily remove the Straight Line Trimmer.

Do not use the Wizard to cut anything wider than 53” from the left edge of the matboard... this INCLUDES the outside cut... without first removing the Straight Line Trimmer.

Turn the shut off valve on the Blue Air Line, and unplug the Blue Air Line by untwisting the Blue Air Fittings.

Turn the bottom locking knob Clockwise to loosen.

Turn the top locking knob Counter-Clockwise to loosen.

Slide the Straight Line Trimmer off of the Board and set aside in a safe place.

Carefully slide the Trimmer onto the channels on the right side of the Board, making sure that the T-Nuts slide into the channel of both the upper and lower rails. Move the Straight Line Trimmer to the left until it stops.

Slowly tighten the bottom locking knob COUNTER-CLOCKWISE until it is snug.

Slowly tighten the top locking knob CLOCKWISE until it is snug.

Plug in the Blue Connector Air Line from the ST 500 into the Blue shut off valve on the “Y” Connector.

Turn on the Blue shut off valve on the “Y” connector to turn on the air.
