General Care
Under normal operating conditions, all OnGrade system components need only minor maintenance.
Following these care instructions can ensure longer equipment life:
• Do not drop the equipment.
• Do not expose the equipment to high heat (such as in the rear window of a vehicle).
• Clean equipment with a damp cloth and mild soap. Never use scouring powder.
• Do not immerse in any liquid.
• Inspect hardware on grade pole to ensure all fasteners are in place and properly tightened.
• Do not mix new and used batteries.
• Remove battery if storing for an extended period.
See manufacturer’s documentation for more information on laser, level, and camera.
Troubleshoot Grade Pole
IMPORTANT: See manufacturer’s documentation for information about troubleshooting laser, level, and
camera.
Issue Possible Cause Possible Solution
Lights on control box will not
indicate a laser “hit.” 1. Obstructions between laser
and grade pole.
2. Elevation of laser is above
or below grade pole reach.
3. Laser plane is out of
distance range.
1. Remove obstructions or do
an offset locate.
2. Use an extension pole on
the grade pole or reposition
laser with an offset.
3. Laser plane range is up to
600’ (183 m) in low-wind
conditions.
Control box lights jump between
high, low and centered. Wind is moving tripod and
causing laser plane to waver. Set tripod as low as possible on
windy days. Use a windbreak for
tripod if possible.
If these steps do not remedy the
problem, take readings when
green light is lit and the upper
and lower lights are flashing
about the same amount of time.
