It's been days now yet the description still says 15 arc second accuracy... Why is your rotary different from everyone elses,

Im not sure where you are looking but as i see it was already changed, here is the link: Topcon RL-H4C Rotary Laser Horizontal Level Dry Battery

I purchased this directly from Panasonic ten days ago and their support told me that its 14000 rpm motor. I am not sure if they sell a different version of the product at Amazon though.

I wondered the same thing. Why set the rpm's and time in hours if it won't cycle?

another way to determine if there is a speed difference is to wrap a piece of tape around the chuck and mark it. you can see the rpm change. mine has no noticeable sound change

Make sure you are not picking up something behind the target. I have never had any accuracy problems with mine. Also, how do you know that it is 100 instead of 90? This model doesn't have gps btw.

A default setting for arc rotation, I have no idea. You will need an adjustment tool to change the range of rotation. I installed my sprinkler system years ago and have about 20 something of these and each one came with an assortment of (red) nozzles. Once installed the rotation limits will need to be adjusted for the proper spray pattern and this is purpose for the adjustment tool. This one I purchased here at Amazon did not include any (red) nozzles or adjustment tool. Hope this helps.

I do not have it at the location I am working from this week but I am pretty sure mine turns to a couple of milimeters no more than 5 milimerters from 60. I've never actually checked to see if the time is 60 minutes or not. We use it to stay on track in 45 minute sessions.

I had same problem. I was using a 4000psi and it was like a flying saucer! Anyway it stopped spinning and I threw it on the bench and took apart bottom plastic bearing, cleaned it up a bit and tighten back up where it would spin freely by hand. it's kind of adjustable and it worked good again. Not that high of quality.

It has variable speed but bear in mind that the speed is controlled by the trigger. The closer you pull the trigger to the drill body, the faster the chuck will turn. However, If by "true", you mean is there a dial where you can set the exact speed ie. 300 rpm or 350 rpm then the answer is no. This feature is more likely found on rotary tools like Dremels, some drill presses and milling machines. I am not aware of any variable speed hand drills that have scales which would enable you to dial in exact speeds. If exact speed is a necessity, then you might want to research rotary tools, bench tools which have a dial that can be set or tools that have a digital display that tells you how fast the chuck is turning. Additionally, I don't know what materials you plan to drill. This drill's range is 0-550 rpm which may or may not be suitable for your intended purpose. I recommend that you study the numerous drill speed and feed guides available on the web to determine if this drill has the best speed range for your project or whether you need a drill with a higher rpm range. It may also be helpful to do a search of materials, material thicknesses, hole sizes, suggested bit lubricants and drill types to see what tradespeople and manufacturers recommended. You can easily ruin costly materials by drilling them at the wrong speed or quickly dull expensive drill bits by using the wrong bit for the material, exerting too much pressure on the bit or not using lubricant. Talk to people who have drilled the same or similar materials. Ask to see if they have any scrap that you can use for test purposes. There is no single drill suitable for all types of drilling. Br prepared to experiment before finally figuring out what works best for you.

My model is 91022 and everything looks the same except for the rotary switch. The rotary switch functions are the same, but the switch positions are not the same.

I have found mine to be very accurate. Perhaps you did get a defective one and should ask for it to be replaced.

Previous answers correct but just note that when setting the time it moves in increments of 15 seconds. You can't set specific times beyond that.

More info: I used it again, but this time I timed it. I guess "time passes quickly when you're having fun," because it actually took a full 10 minutes! Not your 15 but maybe yours is OK. You may have a different make. No idea why I gave the prior answers of 2 -3 minutes and 5. Sorry.

I guess its 1 and 3/16ths then... we're talking less than a centimeter difference between the two measurements. Is it that serious? I was trying to give a roundabout general idea via my discription.

When the Rotadent is working, I think its rotary head function is superior to others i have used. If you need service, forget about it.

I'm not sure Stuart. I saw them when I was looking for some AA's. Looking at the packaging I would say they look longer than a normal AAA. It's possible that it could be a misprint. I find a few misprints on Amazon products from time to time.

Unfortunately, this is based on a 1-hour 360 degree rotation and it cannot be adjusted. Every 15 min it rotates 90 degrees. I would have preferred a different option and actually do not use this because it does not work well for what I want.
