Avoid rubbing the lens, since hard particles from the deposit or the lens cloth can scratch the optical coatings.
• If the greasy deposits do not come off with the lens cleaner, use a lens cloth with a stronger solvent such as reagent-grade acetone as a last resort.
1. Gently wipe the lens surface while continually changing the section of cloth so that a clean cloth is always used on the surface of the lens.
2. Wipe in a circular manner moving from the center of the lens to the outer edge.
3. Do not reuse the lens cloth to avoid redepositing contaminants.
8.6.3 Cleaning Mechanical Parts
To ensure a long, trouble-free service life, wipe down the system regularly to remove any dust or dirt from the system. Most critical components are covered and require no user service. Should the stage mechanics require service, contact your Starrett representative.
8.7 Applying Lubrication
Caution
Use only approved lubricants, as inappropriate lubricants can damage system components. Approved lubricants may be obtained by contacting Starrett or an authorized Starrett representative.
Every 6 months, lead screws can be lubricated with a small amount of lead screw lubricant (Starrett part number 7946). Apply to each screw and traverse the stage or column through the entire range of travel several times to distribute the lubricant. Use a clean, soft cloth or paper towel to wipe up any excess.
8.8 Accessing Components within the System
The main housing of the HDV500 system contains the system’s electronics, which include the system’s computer, M3 controller interface, and CNC amplifiers for the X, Y and Z axes. There are no user-serviceable components inside, and operators will normally never have to open the housing. However, service personnel might need to open the housing to troubleshoot, replace or upgrade system components. The electronics can be accessed by opening the two doors on the right and left sides of the housing. Refer to the following figure. The doors are held closed by three magnets at the front of the housing, as shown in Figure 32.
