While there are many types of sanders out there, using the wrong one will make your sanding job a nightmare. Sanding is an important aspect to great wood floors since the electric sander can help repair, restore or refinish hardwood floors.
In a nutshell, Jellas 7Amp 3"x21" belt sander is on the powerful side, able to strip down a piece of wood in a short amount of time. Smoothing and shaping wood best on large, flat surfaces, and can strip off not just wood but coating materials like paint and metal(Should use corresponding sheets for metal sanding). If you’re looking to strip down and finish entire planks, a Jellas belt sander is a good choice because it will offer pretty uniform results across the breadth of its sanding surface. And it is easy to control.
When installing the sanding belt, please keep the arrow on the belt in the same direction of the arrow on the machine, which enables the belt a longer life, avoiding leaving scratches on the board.
Carbon brushes are a very important part of the 7Amp sander machine. Jellas high-quality carbon brushes make the belt sander have a longer service life.
The dust bag has higher dust collection efficiency than the dust box, and the dust bag has air permeability to prevent dust from entering the motor again, so that the service life of the belt sander is longer.
The 3"x21" sander machine comes with 10pcs Sanding Belts (2pcs 40 grits, 2pcs 60 grits, 2pcs 80 grits, 2pcs 120 grits and 2pcs 180 grits aluminum oxide sanding belts), they satisfy more needs of the change of the bands.

Warm Tips
√Always ensure that the machine is switched off and plug is removed from the power point before making any adjustment.
√Run the sander for a minute or to ensure correct alignment before using the sander on a workpiece.
√For longer periods of use or on large pieces of work, it is advisable to use a suitable vacuum cleaner. (32mm and 35mm vacuum cleaner ports both fit Jellas Belt Sander)
Steps to attach a sanding belt:
Step 1, Select the required grade of sanding belt.
Step 2, Pull the belt tension lever
Step 3, When attaching a sander paper, please slip a sanding belt by the direction of arrow shows on the sander.
Step 4, Fold down the lever
Step 5, While the belt is running slowly, adjust the tracking adjustment knob to align the belt to the centre of the roller.
Step 6, Repeat the trigger action and tracking adjustment until the belt is aligned correctly.
Step 7, Before using the sander on the workpiece, run the sander for about one minute to ensure correct alignment.
Do not continue to use the sander with a sanding belt that is overworn or damaged. Do not use the same sanding belt for wood and metal. Metal particles become embedded in the belt and will scour a wooden surface.

Well designed and strong sander with many features that allow easy operation, variable speeds and long cord. Sawdust bag is effective (better than most products). And many sander belts were provided with various grits which was an added bonus. Great Value!

This is a pretty nice sander, and unlike some of the other Chinese junk, it didn't fail right away. I've used it about 2 1/2 hours on Walnut, dumped about 2 cups of sanding dust from the bag, and I'm generally pleased. There are a couple of downers, though. First is the blast of cooling (?) air that hits you in the face when you're above it. Thankfully, that's separate from the dust collection air. Which brings up the second downer. The dust bag is retained by a circular wire spring, like a hose clamp, and there's a 1/2" hole upstream from the spring, facing up when the bag is in it's proper position. LOTS of dust exits through that hole, such that my hand was thoroughly covered with fine dust after an hour and more had blown around. Need to add some sort of clamp or barrier to stop that. The belts seem good, but the finest one had a "bumpy" joint, and I never did know why one of them left tracks as if it was digging beyond the platten. Tracking was not a problem, unlike other viewers reported, so perhaps it's a belt problem, not a sander fault. It's powerful, so it's loud; wear muffs, and because of the dust, wear a mask.

I bought this in April of 2024. I use it around 10 minutes of run time a month. It is a well designed machine. I have had no problems with the belt drifting and the clamps are incredible. You can't beat it for the price.

I love the clamps that make a stationary belt sander, it's like getting two tools for the price. I do wish the Jellas would offer an adaptor for the dust port so it can be connected to a more standard 1" home shop system. I had to make one.
