Model Nos.  40-6520 and 40-6530

Instruction Manual

Congratulations on your choice of this Self-Leveling Rotary Laser
Level. We suggest you read this instruction manual thoroughly before
using the instrument. Save this instruction manual for future use.

This tool emits one rotating laser beam level line that is ideal for layout
of indoor or outdoor construction projects. Since the product is
equipped with a beam detector (in model no. 40-6530 only), visibility of
the beam in various lighting conditions is not an issue.

This is a Class IIIa laser tool and is manufactured to comply 
with CFR 21, parts 1040.10 and 1040.11 as well as international
safety rule IEC 285.
