Things You'll Need:

- Replacement bar
- Wrench
- Screwdriver

Step 1
Press the oil squeeze bulb on the chain saw to oil the chain and guide bar while the saw is operating.
-
Step 2
Follow the instructions for your model to remove the guide bar for cleaning. Typically, you'll remove the side sprocket case and unscrew the guide nuts.
-
Step 3
Use a wire or putty knife to scrape away sawdust and other debris along the bar. Move the wood chips and debris away from the nose toward the base. The sprocket nose must be able to spin freely.
-
Step 4
Clean oil slots for the chain and bar after each use to maintain oil flow.
-
Step 5
Look for burrs on the sides of the guide bar. File the bar to keep the sides square.
-
Step 6
Inspect for cracks, bends and uneven wear on the rails. Replace the bar when you see any of these defects. Look in the manual for the product code, and then order a new bar or buy one in any store that sells chain saws.
-
Step 7
Check that you have enough chain tension. Usually, this involves loosening the bar nuts and setting an adjustment screw so the lowest cutters and straps touch the bottom of the bar. Check your manual for the procedure and the proper sizes for your wrench and screwdriver.
