O-rings are designed to contain thousands of pounds of pressure by creating a seal between two or more parts. O-ring measurements are defined by the inside diameter and the thickness. There are many causes for O-Ring failure, such as pressure, friction, temperature or chemicals. The most common are: • <u>Extrusion and Nibbling</u> O-ring has ragged, tattered edges. These are commonly caused by pressure spikes which shear off tiny "bites" from the o-ring, or caused by clearance gaps. • <u>Abrasion</u> One or both sides of the o-ring appear rough and slightly flattened. Commonly caused by a contact surface that is too rough, contains grit or is too smooth to allow lubrication. • <u>Over Compression</u> O-ring is flattened on both sides and may have a "ring" split along its length. Commonly caused by excessive pressure or heat. • <u>Heat Hardening</u> O-ring has a pitted or cracked surface, and often is flattened on both sides. Caused by temperature exceeding o-ring capacity. • <u>Weather/Ozone Cracking</u> O-ring is covered in small surface cracks. Caused by exposure to ozone, UV rays and air pollution. Excessive seal stretching causes similar cracking.
1. Disassembled handle to access switch assembly
2. Referred to blow up diagram to see all parts and assembly sequence
3. Installed new part ( safety release button) in switch assembly

... Read moretrigger release mechanism in the switch assembly..pieces tend to fall out.. better to lay the saw on its side to keep pieces in place.
Replacing motor brushes was very easy.. only required a flat blade screwdriver
Installed the o-ring on the elbow to keep it on. Removed the fence and the old kerf boards and installed the new ones. Removed the brush caps, then the old brushes and installed the new brushes, then replaced the brush caps.
I purchased the correct replacement parts from eReplacementParts. I\'ve had this Makita saw since the 90s and used it to replace all the base moulding in my house. 20 years later I pulled it out to use it and found the dust bag was torn. Makita had discontinued the original bag with a superseded PN that didn\'t fit the original plastic el
... Read morebow. I thought I was going to have to buy a new Makita Compound Miter saw. Then recently I found on the Makita website eReplacementParts had the replacement bag, plastic elbow and o-ring for my 20 year old saw. I\'ve been so happy I found these parts -- so I bought a lifetime supply. Thank you eReplacementParts. You saved me $700!
I bought the O Ring and the Elbow in order to put in the Dust Bag on to the machine. It takes me about 15 seconds.
