Getting Started
• We recommend using a large at, clean working surface for assembling your E3.
• All screws (unless noted) should be installed snug, then rotated one 1 to 2 1/2
turns.
• Light sanding of the wood surfaces will clean up the marks made by the laser.
• Painng or applying stain with a clear coat will give added protecon to the wood
