Preface
Never attempt to look at the laser beam directly. Laser beam is harmful for eye.
It is safer when laser beam rotating. Because passing through only for a short time.
1-1 Notes
SP50 is an automatic electronic laser level with laser diode of 635nm wavelength. Before repairing,
pay great attention to important precaution as follows.
Description of the laser unit
Be sure good body grounding to prevent laser diode from short life time caused by static electricity
in the unit.
1. Before disconnecting the plugs of the laser unit from the jack, turn power switch off.
