Troubleshooting
The Laser Does Not Turn On
• Make sure batteries are installed according to (+) and (–) on the inside of the battery door.
• Make sure the batteries are in proper working condition. If in doubt, try installing new batteries.
• Make sure that the battery contacts are clean and free of rust or corrosion. Be sure to keep the laser level dry and use only new,
high-quality, name brand batteries to reduce the chance of battery leakage.
• If the laser unit is heated above 120˚F (50˚C), the unit will not turn on. If the laser has been stored in extremely hot
temperatures, allow it to cool. The laser level will not be damaged by pressing the on/off button before cooling to its proper
operatingtemperature.
The Laser Beams Flash (Fig. C, D)
The DW088 lasers have been designed to self-level up to an average of 4° in all directions when positioned as shown in
FigureC. If the laser is tilted so much that internal mechanism cannot level itself, it will flash the laser (Fig.D) – the tilt range
has been exceeded. THE FLASHING BEAMS CREATED BY THE LASER ARE NOT LEVEL OR PLUMB AND SHOULD NOT BE USED FOR
DETERMINING OR MARKING LEVEL OR PLUMB. Try repositioning the laser on a more level surface.
The Laser Beams Will Not Stop Moving
The DW088 lasers are precision instruments. Therefore, if the laser is not positioned on a stable (and motionless) surface, the laser
will continue to try to find level. If the beam will not stop moving, try placing the laser on a more stable surface. Also, try to make
sure that the surface is relatively flat, so that the laser is stable.
Service and Repairs
NOTE: Disassembling the laser level(s) will void all warranties on the product.
