3. CARE AND MAINTENANCE
Your Northwest Automatic Levels are designed to be used generally in civil engineering and construction
as well as for farm, mining and forestry industries. With the appropriate care, your instrument will need only
minimal routine maintenance and minor adjustments under normal field use. In case your instrument is
damaged or abused, it should be taken to a qualified instrument repair facility or returned to Northwest
Instrument for repair.
1. The instrument should be kept encased properly when not in use for maximum protection.
2. Keep the instrument clean and free of dirt and moisture. After use, clean every part of the instrument
completely before putting it back in its case.
3. If the instrument becomes wet, wipe off moisture completely, taking special care of the lenses by using a
soft clean cloth or Lens tissue.
4. Do not attempt to clean, oil or repair interior parts. Do not remove any lenses or the compensator. This
should be done by a qualified repair technician only.
5. When working near moving equipment, never leave your instrument unattended.
6. Always spread the tripod legs to insure a stable setup. When setting up on pavement or other hard
surface, try to protect the legs from slipping by using tripod ties.
7. After working in dusty locations, remove all dust from the lenses with a clean, soft tissue or cloth and
brush the leveling and tangent screws threads with a small brush.
8. Make sure not to over-tighten the leveling screws.
9. It is recommended that you have a qualified service technician check your instrument periodically.
