Setup

Operating Instructions
This level is designed for accurate measurement of horizontal and vertical planes.
Measuring Horizontal (Level)
- Place the bottom edge of the level firmly on the surface you wish to check for levelness.
- Observe the horizontal vial (typically the longest vial in the center).
- Adjust the surface or the level's position until the air bubble in the vial is centered precisely between the two indicator lines. When centered, the surface is level.
Measuring Vertical (Plumb)
- Place the side edge of the level against the vertical surface you wish to check for plumbness.
- Observe one of the vertical vials (typically located at the ends of the level).
- Adjust the surface or the level's position until the air bubble in the vial is centered precisely between the two indicator lines. When centered, the surface is plumb.
Using the Top-Read Window
The top-read window allows for convenient viewing of the horizontal vial from above. This is particularly useful when working in situations where direct eye-level viewing is difficult or when standing over the work.
Maintenance
Proper care will ensure the longevity and accuracy of your level.
- Cleaning: Wipe the level clean with a soft, damp cloth after each use. Avoid abrasive cleaners or solvents that could damage the finish or vial clarity.
- Storage: Store the level in a dry place, away from extreme temperatures. Avoid storing it in a way that could bend or warp the frame.
- Vial Protection: While the vials are durable, avoid dropping the level or subjecting it to severe impacts, which could damage the vials or affect accuracy.
- End Caps: The non-slip end caps are removable for specific tasks. Ensure they are securely re-attached when not removed for use.
Troubleshooting
Most issues with a spirit level are related to physical damage.
- Inaccurate Readings: If you suspect the level is providing inaccurate readings, first check the level's frame for any signs of bending or warping. A bent frame will compromise accuracy.
- Damaged Vials: If a vial is cracked or leaking, the level's accuracy will be affected. Such damage typically requires replacement of the level.
- Bubble Not Moving Freely: Ensure the level is clean and free of debris that might obstruct the bubble's movement within the vial.
