Using the Straight Line Trimmer

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.
