Raising and lowering blade almost impossible. How do I repair it

the blade is raised and lowered via a screw (long one) that you turn with a handle as with any mechanical item that moves , keeping it clean and lubricated is critical , I use candle wax on all my saws (not bee's wax) , as sawdust doesn't stick to it as much as a petroleum oil would cause, and it never mars my wood panels or stains it with a drip mark

I can't raise my table saw blade when I crank the handle

My DeWalt Table saw does this,and for me its cleaning with a air compressor and nozzle. I cand seem to prevent it though. I tried grease on time and it just plugged up faster. I want to try a gravite lube next. To me it seems to be a desiegn flaw and I just clean the spline thead shaft that lowers and raises the blade. So far I just settled into a maintance air spray and it seems to work well enough.

The blade is hard to raise and lower

Check the threaded rods that turn to move the motor assembly up and down. These rods are sometimes oiled or greased and this just attracts saw dust and eventually binds up the system. Clean as best you can and the threads they turn in to raise the blade. Also check the tilt rods.
Another thing to check is the joints everything pivots on. Occasionally a small peice of wood can get in just the right (or wrong) place and the motor assembly won't move because it's blocking the pivot points.

My powermatic table saw is very hard to raise and lower the blade and i have removed the knob that tightens the handle so the blade does not move and its still very difficult to move the blade

You need to do some maintenance on your saw. First unplug it. Then blow out the sawdust from inside the saw, especially around the trunnion ways and gears and worm gears that engage them to raise/lower and tilt the saw. Use a good quality lubricant to lube these worm gears and the shafts and pivot points. I use motor oil, have for years, and find it does a better job and lasts longer than any kind of grease or silicone. Use an oil can with a long spout so you can direct the oil where needed, then move the saw up/down or right/left to work the oil into the worm gear and mechanism. In a pinch WD40 is fine, though it won't last as long. Periodic re oiling will maintain the mechanism in peak condition, and the drops of oil you spill in the process won't do any damage to your so. No, it won't get gummed up with sawdust. Try it, you'll like it.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

Freezer is to cold and refrigerator not cold enough. When you open freeze it is always running

Sounds like the fan that cools the lower refrigerator is inoperative or it's fan blades frozen up.
Try defrosting. You will have to remove everything and remove the access panel to the fan to ensure it's fan blades are free and not frozen up. They have a built in inherent safety feature and sometimes they will work properly again when thawed out. More than likely the small fan motor burned out and will need to be replaced. There are appliance parts stores every were or call the mfgr parts department.
Once replaced your can restore your freezer setting to where it belongs. There is a dial that raises and lowers this setting.
The small fan draws air from the freezer and cools the refridgerator. It is also on a thermostat and usually has a dial to set the way it cycles and determines the temperature.

My 10 inch saw is 20 years old. It is very hard to raise and lower the blade. Everything is clean yet it is very hard. Any ideas?

over the years the yoke nut the screw goes through has built up grit . Spray the screw with WD 40 as you raise and lower the blade , also look to see as you turn if screw is bent.

It's extremely hard to turn the handle to raise the blade. Lowering the blade is smooth and easy, but I have to apply an excess amount of pressure to turn the handle when I want to raise the blade.

If this is a new saw, return it to the store for an exchange, but if it's an older than a few months:

These contractor saws often acquire this problem. It's usually dust, specifically pine dust (it has sap thus making it stickier), on the screw or the sliding mechanism. What I do is:

  1. Unplug the saw
  2. Remove the blade
  3. Dismount the saw from its stand
  4. Lower the mechanism all the way
  5. Flip the saw over onto its table
  6. Access the screw and the lift mechanism
  7. Use a brush to remove the accumulated wood dust from the screw and the mechanism.
  8. If you have a leaf blower or access to one; blow the interior of the saw (wear eye protection always!)
  9. Do NOT oil the mechanism, this will only serve to gum everything up faster - use a dry lubricant (graphite or silicone) or none at all.
To avoid this in the future;

  1. Avoid resinous woods (not a likely solution).
  2. Blow the dust from the saw interior when finished using it (this works well) - use an air hose or a leaf blower, the leaf blower actually works best.
  3. After cutting and before stowing the saw; run the blade to its highest position and then down below the table. This pushes any dust off the mechanism and screw.
If you find little or no dust accumulation, it's possible the saw has a bent screw or binding mechanism and will require service.

Always be safe; unplug the saw and remove the blade when working on it, and always retract the blade below the table when not in use to prevent damage to the blade - or being cut by an exposed blade; they're sharp!
