Lubricant belt zoom - Nautilus Ntr 800 Treadmill Lift Motor

It could be because it is overheating due to the fact that the floor belt is too dry and the motor is labouring hard to spin the floor belt. When was the last time you lubricated the base of the floor belt (the flat base where the floor belt slides on)? A couple of little sprays of Silicone Lubricant should ease the motor workload as the floor belt rolls on. If you're a big person, the excess weight also tempts to dry the floor belt quicker and if you're running on it while the home is being heated in winter of during warm summer days, or you are training on carpeted or linty areas, all the excess heat and dust dries the floor belt faster and need to be lubricated more often. Lift the floor belt and feel with your hands if there is any lubrication. A wet feel means it is lubricated, while a dry feel or sticky hand as you move your hand left and right means it is dry. Dry belts are the blame of 80-90% of motor failure and or seizures due to lack of care and maintenance. Lubricate it once per month. If you don't like spraying Silicone lubricant directly under the floor belt, do this; find a lint-less rug such as a kitchen drying cloth and go outside the house, spray the Silicone lubricant on the cloth to lightly soak it and then go to the treadmill, lift the floor belt and apply the wet cloth evenly on the base until you believe it is lubricated enough to make the rolling of the belt with ease. Run it for half a minute at slow speed (walking pace) before you can safely use it for running or jogging, etc.

You would have to disassemble the lens barrel to get to the zoom sliders, and lubrication is not likely the problem anyway. The zoom mechanism uses nylon bushings sliding in a groove, and zoom problems are usually due to wearing/cracking of those bushings.

If it's still in warranty, send it in. Otherwise, the cost of repair probably exceeds the value of the lens. Sorry.

Very slight lubricating spray should suffice ..... but see to it that its very little .....

Some ProForm treadmills require lubrication every six months or so, depending on the usage amount. Lift the walking belt and feel on the underside of the belt. If it is dry, you should lubricate it. ProForm recommends you use 100-percent, non-petroleum silicone spray to lubricate the walking belt. Do not use wax or other lubricants, such as WD-40 or a Teflon-based spray

hi,
Your treadmill walking belt need lubrication. For lubricating use Teflon silicon lubricant. To know how to lubricate the treadmill belt watch the following video.

Susan,

The most common cause of belt slippage is lack of lubrication. Most treadmill belts use lubrication on the underside of the belt to reduce friction between the belt and the platform. This helps the treadmill glide along smoothly under the weight of a person. If your belt is lacking in lubrication, it can catch on the treadmill platform. Apply lubrication every few months to the underside of the belt to prevent this from occurring.

A petroleum or silicone based lubricant is recommended, and most easily applied in a spray can. Simply lift up the belt about midway along the platform and spray a small amount of lubricant underneath from about the middle of the platform width to the closest edge. Repeat from the other side. Apply lubricant sparingly...it can be messy.

Next, turn on the treadmill and let it run for a minute, then check if the belt still sticks. A little more lubricant may be necessary.

Hope this helps.

Put some WD-40 on a cotton swab, squeeze the tip and let it drizzle down into the zoom switch.

Its more like a distorted inner zoom barrel or sand and dirt inside  the inner barrel will need to be replaced or you need to dismantle and clean out
