RYOBI Jigsaw doesn't cut square

The Jigsaw may not be cutting straight because:

• The blade might be excessively worn, bent, damaged or not installed correctly.
• The quality of the blade may also be the cause as inferior quality blades can warp or deform when in use, even if the blade is square after use; a higher quality blade is often thicker and will stay sharper much longer.
• As Jigsaws are a free moving tool, it is possible for the tool to drift from the cut due to human error – you may want to consider using a straight edge to assist.
• Ensure the blade is matching the material thickness. For example, thicker material requires a thicker blade.
