Optics - Recent Questions, Troubleshooting & Support


I know nothing about laser rangefinders - sorry.

I think you will find the answer to your question in the price point of the device and the age of it. In the first instance I suggest you contact the manufacturer to check whether they provide a repair or exchange service or whether they have a network of approved repairers.

Trying to figure out how old my Whirlpool washer is Locate your machine's nameplate, which contains both the model and serial numbers. On top-loading Whirlpool washing machines, open the lid and look for the tag at the top rear of the tub. On front-loading washers, the tag is usually inside the door or near the bottom of the left or right side of the cabinet. If the tag is not in one of those places, pull the machine away from the wall and check the rear. Record the serial number with a pencil and paper or take a photograph. Be sure to record the serial number, not the model number. Decode the serial number at an online source like Appliance Cafe or Appliance 411 (links in Resources). Whirlpool serial numbers include a code in the second character for the year the product was built. Before 1990, the character was a number; from 1990 to 2010 the character was a letter. The number sequence started over in 2011.

Lens coatings sometimes aren't as robust as they should be and some of the lenses are compound types and take a deal of dismantling/reassembly.

I suggest, if you aren't used to servicing optics you should entrust the work to a specialist, especially as Pentax is a fairly premium product.

You might be able to drill a hole through the plastic knob and use a washer and a bolt to hold the screw tight. Or do something like this fix:

They are only 15 dollars to buy new. With that in mind you could attempt to rebuild it but you need at least a micrometer to measure clearances. The pictures that I am looking at show a fiber retainer and a washer seal unit. You need to see if you can get those parts individually. The fiber washer may soften if you wet it and this would make it easier to insert it because the edge of the case appears tapered. However if you do that you need to be able to dry it in its original dimension.
