2. PRECAUTIONS
10
Other precautions
• Protect the instrument from heavy shocks or vibration.
• When setting up the instrument, position it so the bubble in the digital level vial on the display
is in the center position.
• When you remove the instrument from the carrying case, be sure to open the cover of the
case after laying the case down, right side up.
• Consult your local dealer before using the instrument under special conditions such as long
periods of continuous use or high levels of humidity. In general, special conditions are treated
as being outside the scope of the product warranty.
• Physical reflection and refraction may occur under hot weather conditions or in a small pipe
diameter due to its temperature or moisture conditions, which could interfere with the
precision or available range of the instrument. To minimize the effect of these conditions
please take the following precautions.
1)Place the pipe hot side (heated by sunlight etc.) down.
2)Do not apply an excessive amount of "pipe adhesive" to the pipe joints.
3)Immediately back fill the trench as pipe work is finished.
If it is difficult to follow the instructions noted above, please use a blower (commercially-
available) or place the instrument on the pipe before performing the operation.
User
• Wear the required protectors (safety shoes, helmet, etc.) when operating.
