They are located next to the Head Wheels and are marked with red dots.

Do not touch the Allen Screws attached to the Wheels themselves.

Loosen each Head Wheel Adjustment Allen Screw until the Wheels are loose; about two full turns.

The Wheels are spring-loaded and will pop into place.

Grasp the

Head with both hands and gently rock it back and forth to ensure that the wheels are lined up to the

Gantry grooves.

Retighten the

Head wheel adjustment Allen screws consecutively; tighten the top screw half a turn, then the bottom screw half a turn, back to the top and continue until they are both tight.

Check each of the

Head wheels to make sure there is no movement.

There are the two visible wheels on the left side of the

Head under the blade depth adjustment plate, and two wheels on the backside of the

Gantry, which can be felt by hand.

They should sit firmly into the

Gantry groove and be difficult to turn. If not, repeat these steps of loosening the wheels, gently rocking the

Head back and forth, then retightening the wheels.

Reinstall the hoods onto the Gantry, replacing the screws you removed earlier.

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.

Do a test cut. Cut a 2x2 square, with 2” borders, NOT cutting the outside. Measure the border to the opening and make sure it measures 2”. If it does not, adjust the Horizontal Home in the Configurations Screen accordingly.

• If the border is too big, decrease the Horizontal Home.

• If the border is too small, increase the Horizontal Home.

Do another test cut. Continue making adjustment until it measures 2”. If you need assistance, call Customer Support.

Make sure that the Gantry is straight. Cut a rectangle that is about 2x24”, NOT cutting the outside, with 2” borders.

Measure the borders to the opening at the bottom of the mat closest to the vertical clamps, then measure the borders to the opening at the top of the mat closest to the vertical clamps.

If the borders are not measuring 2” in both places, call Customer Support for assistance.

Check both sets of wheels at the TOP of the

Gantry.

Make sure all of the wheels make contact with the top rail, and that they don’t spin freely.

Make sure they are making contact with the top rail.

If any of the wheels are not making contact, contact customer support.
