3 in 1 sewing machine Just lube up the pins, bolts and play with the adjustment lever. you'll get your adjustment arm to raise and lower in no time! If you don't have 3 in 1, a few shots if "Jig a Loo" or "WD40" will quickly remedy the situation.

Changing blade on Ryobi chop saw


Unplug the saw. If the blade is moving, wait for it to stop. If the blade arm is locked into its down position, push down slightly on the blade arm to release the tension on the blade arm lock pin. Pull out the lock pin to release the blade arm and allow it to move upward.
2 Rotate the lower blade guard upward and expose the Phillips-head screw that holds the blade bolt cover in place. Loosen the screw and rotate the blade bolt cover up and out of the way to expose the hex-head blade bolt.
3 Push the spindle lock button in and rotate the blade bolt until the spindle lock engages fully, stopping the ability of the blade bolt to rotate.
4 Loosen the blade bolt using a 10-millimeter/12-millimeter combination wrench. The blade bolt is lefthand threaded, which is the reverse of conventional threading. Turn the bolt clockwise to loosen and remove it. Note the placement of the outer washer and remove it as well.
5 Place a drop of machine oil on the inner blade bolt washer. Do not remove the inner washer. If it is missing, replace it before replacing the blade.
6 Slide the replacement saw blade up past the lower blade guard and onto the blade spindle. The blade teeth should point downward at the front of the saw. Saw blades often have rotation arrows that can help you double-check that the saw is installed to rotate the correct direction.
7 Press the spindle lock button in to lock the spindle and reinstall the blade bolt. The blade bolt will tighten in a counterclockwise direction. Replace the blade bolt cover and install the blade bolt cover screw.
8 Position a combination square to check that the blade is square to the saw fence and saw table. If the blade is not square, refer to the procedures in the manual for squaring the blade to the fence and table.
Things You Will Need
  • 10-millimeter/12-millimeter combination wrench
  • 5-millimeter hex key
  • Combination square
  • Phillips screwdriver
  • Machine oil
Tip
  • Overtightening bolts and screws can result in cross-threading. Cross-threading damage compromises the integrity of bolts and screws and can be a difficult error to correct.
Warning
  • Do not attempt to install a blade that is too thick in the saw. If the blade washer cannot engage the flats on the spindle, the blade is too thick for the saw.

De Walt radial arm saw old model 7740. Am trying to restore it to working condition Very difficult to change the height adjustment due to binding when trying to turn the handle on the top.


The manual for the saw is included below, To free the height it may be best to remove the saw carriage from the arm to reduce the weight.

Use WD40 or equivalent to cut the rust and a suitable grease to maintain the freedom. There is a worm screw that is below the cylinder that may need lubricating. The manual shows the assembly. I routinely apply 90 weight gear oil around the large tube where it goes into the housing,

I can lower theblade but it is very difficult to raise and now its not raising at all just gets tighter until you hear a snaping sound


Try spraying the pivot points with soy based lubricant. It is very slick and should help ease the friction of raising the blade.

Lost ability to raise the blade for operation.


Most often this is caused by the handle or wheel that is used to raise/lower the blade coming loose on the shaft that operates the worm gear in the trunnion. There is frequently an allen set screw that locks this wheel onto the shaft and this set screw comes loose or is lost. If loose, simply tighten it.
Otherwise, it may be time for some routine maintenance. Unplug the saw, clean all sawdust and debris from under the saw using compressed air if possible, and then lubricate the worm gear/gear box and trunnion ways. Some people prefer silicone for this, some use WD40. I prefer normal motor oil. In any event you will need a long oil spout to direct the lubricant into the worm gear and gears, then/while raising and lowering the saw. Also lubricate the angle adjustment gears.
If you keep your saw properly lubricated, it will function easily and be a joy to adjust. Otherwise, it can become a struggle or just impossible.
Good luck.

HOW DO YOU UNLOCK THE ARM ON A DELTA MITER SAW 36-075, IT IS NOT A STAND BUT THE ARM ITSELF?


Here is a link to an exploded parts diagram and instruction manual for that saw.
Normally, all that is required is that you unscrew the handle and turn the table, then lock the handle in the desired position. But as with many older saws, the table may become jammed with dust and foreign objects and need to be cleaned and lubricated in order to work properly.

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

We found leaking oil underneath one side of the lifting arms on our Tuntuiri walking machine. We thought it was coming out of the lifting arm shockies or arm somewhere. What can we do? Sophia


hi,
Its normal. Its the silicon lubricant used to lubricate the treadmill belt. If there is excessive lubricant it will spill out. Don't worry about it. It will become normal within days. just wipe off the excessive lubricant coming out.Its coming out from the running base under the running belt.
ok

I have a 1680 scrollsaw and no manual. Where is oiling required?


Lubrication

ARM BEARINGS

Lubricate the arm bearings with oil after 10 hours of use.

Re-oil after every 50 hours of use or whenever there is a

squeak coming from the bearings.

TO LUBRICATE

1. Turn saw on its side (Fig. 18).

2. Remove rubber plug to expose bronze bearing.

3. Squirt a generous amount of SAE 20 oil around the shaft

end and bronze bearing.

4. Let the oil soak in overnight in this condition.

5. Next day repeat the above procedure for the opposite
side of the saw.

How do you put in a ball joint in a 2001 sebring convertible


It depends on exactly which ball joint of the 3 per side your changing, but here are the details.

COMPRESSION LOWER ARM & LATERAL LOWER ARM ASSEMBLIES
Removal
1. Loosen compression lower arm ball joint nut. Using steering linkage puller, separate ball joint and
knuckle. Remove nut, bolts and compression lower arm assembly. Remove dust cover.
2. Remove stay. Remove shock absorber lower mounting bolt. Loosen lateral lower arm ball
joint and knuckle nut. Using steering linkage puller, separate ball joint and knuckle. Remove nut, bolt and
lateral lower arm assembly. Remove dust cover.
Inspection
Using preload socket, ensure breakaway torque for compression lower arm ball joint is 4-22 INCH lbs. (0.5-2.5
N.m) for 2000 models. On 2001 models, breakaway torque is 22-54 INCH lbs. (2.5-6.1 N.m). Ensure
breakaway torque for compression lateral lower arm ball joint is 13 INCH lbs. (1.5 N.m). Check compression
lower arm, lateral lower arm, dust covers, and bushings for damage and wear.
Installation
To install, reverse removal procedure. Use NEW ball joint nuts. Lubricate lip and inside of dust cover with
multipurpose lubricant. Using installer, install dust cover. Check front wheel alignment.
UPPER ARM ASSEMBLY
Removal
Using steering linkage puller, loosen upper arm ball joint and knuckle nut. Remove self-locking nut. Remove upper arm and upper arm shaft assembly. Remove dust cover.
Inspection
Using preload socket, ensure breakaway torque for upper arm ball joint is 3-13 INCH lbs. (0.3-1.5 N.m).
Replace upper arm assembly when measured value exceeds specification. Check upper arm, dust cover, and
bushings for damage and wear.
Installation
1. To install, reverse removal procedure. Use NEW self-locking nuts. Lubricate lip and inside of dust cover
with multipurpose lubricant. Using Ball Joint Installer (MB990800), install dust cover.
2. Ensure upper arm shaft assembly is installed at indicated angle. Verify upper arm shaft
assembly installation. Check front wheel alignment.

Once you have the correct arm off and a replacement joint (if available, some are not serviceable and require the arm to be replaced) then you will need a press or a ball joint press to change the joint. Such as
