Green Laser Technology™
PowerLine™ Magnetic-Laser “Sheave Alignment System”
Instructions
The PowerLine™ Sheave Alignment System aligns belts, pulleys, sheaves, sprockets, gear trains, rollers,
platforms, conveyors, and other plant equipment. Its purpose is to replace often times inaccurate and time-
consuming straightedge and string alignment methods currently in use. Compared to these older methods,
the PowerLine™ is easier, faster, and more accurate. With the PowerLine™, you will greatly reduce
downtime and belt failures. The new Green Laser Technology™ and reflective target system increases the
brightness of the laser line by 10 fold. This means that the system can be used in direct sunlight and at
longer distances.
Component Descriptions: The PowerLine™ Sheave Alignment System includes a laser line emitter and
three grooved targets. All components are especially rugged for long life and are shipped in a sturdy
storage case.
Laser Line Emitter: Its bottom machined surface mounts magnetically to the machined face of sheave,
gear, etc. It projects a 1/16” thick laser reference line over a wide angle. The projected reference line is
parallel to the machined bottom surface and offset from it by 0.312”.
Warning and Certification Label Bottom Surface is on Back Side
Laser Safety: Caution- Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
The PowerLine™ emitter uses a laser diode with a maximum output power of less than <1 milliwatt @ 635
nm. The laser classification is Class II < 1mW @ 532nm with only minor precautions required. Never
stare directly into the laser transmitter or aim the laser into someone’s eyes. The PowerLine™ complies
with 21CFR parts 1040.10 and 1040.11.

Excellent alignment is achieved when laser
line hits here on center of target groove. This
reference can be adjusted up or down to
compensate for sheaves with different thickness
by turning knob.
Initial knob setting is to
extend the magnet bottom
outward from the target
bottom by one full turn
(1/16”) so target groove
center is elevated 0.312”
off magnet bottom. Adjust
knob up or down from this Knob on top
