How to sharpen a chainsaw chain

Keeping the chain sharp is very important, because a blunt chain increases the chain saw blade that starts upward after the chain sinks into the woods. This condition is commonly referred to as recoil, and it is one of the most common causes of injuries to chainsaws. Increased fuel consumption and excessive damage are two other reasons to avoid blunt chain cutting. Read on to learn the basics of using a file or electric grinding wheel to grind a chain.

There are two main methods you can use to manually sharpen the chainsaw chain by using a circular chainsaw file or an electric saw grinder. The third method, the square file, is only used to cut square chains of large trees. These instructions are only general guidelines. For setup usage and instructions, please refer to your grinder manual. Polish your chain to make it conform to the manufacturer's recommendations. Use rapid tapping motions to minimize ground overheating.

When to sharpen a chainsaw chain

Check whether the chainsaw chain is damaged and whether it needs to be repaired or replaced. Sharpen the chain every time you lubricate the chain saw. If the sawdust on the chain looks like dust (rather than debris), the chain is dull and needs to be sharpened. Having to force one's chain to be cut is another sign that the chain has become dull.

Step by step: what to do before sharpening the chainsaw chain

What you will need

gloves

protective glasses

Electric saw file kit (round file, file guide, flat file and depth gauge measuring tool)

step 1

If you have any questions about strengthening the service chain in Oregon, please call 800-223-5168 from Monday to Friday at 7:30 am and 4 pm to contact our technical service department. PDT.

Step 2

Before sharpening a chainsaw, you need to understand the type of chain and the specifications of the sharpening angle. You can find this information in the chain saw user manual or in the chain bag. The chain identification code is usually written on the driving link.

step 3

Wear protective equipment, including gloves and goggles.

Step 4

If you sharpen the chain saw while it is fastened to the chain saw blade, make sure that it is tensioned correctly first.

Step 5

Before performing any maintenance, make sure that the chainsaw is turned off.

Step 6

Wipe off the grease from the chain. This step will prevent accumulation on the teeth of the file or the grinding wheel during grinding.

Step 7

Check whether the chainsaw chain is damaged.

This is what you should pay attention to:

Install cable ties and drive chain correctly

The cutter is broken, broken, the top plate of the cutter or the cable tie

Drive link is bent, cracked or burned

Severe abrasive damage

Abnormal chain wear

The wear pattern may indicate that the rod or sprocket is worn. For more information, please refer to the Oregon Saw Chain Safety and Maintenance Manual.

The rivets are loose (try rotating the rivets with your fingers-if you can do this, they are too loose.)

Step 8

If you want to archive the chainsaw chain manually, please select and use the correct file guide and file for the chain. This is the easiest way to file a saw chain.

Step 9

If the chain is damaged, repair or replace it.

Step 10

Check and adjust the depth gauge.

Step 11

Make the chain more in line with the manufacturer's recommendations and maintain balance.

Step by Step: How to use circular file sharpening

The purpose of archiving is to eliminate all damage while maintaining the balance of the chainsaw chain.

What you will need

gloves

protective glasses

Chainsaw file kit

Chainsaw chain

step 1

Engage the chain brake, and then gently clamp the wire saw of the vise in the vise. Then release the chain brake so that the chain can be rotated manually (gloves must be worn when performing this operation)

Step 2

If you are using a document guide, place it on the cutter head and place the document in the tooth groove (between the cutter head and the depth gauge). Make sure that the document guide has two contact points, one contact point is on the top plate of the cutter, and two contact points are on the depth gauge.

Step 3

Keep the document in the correct position so that 1/5 inch (20%) of the document diameter is above the top plate of the cutter. Using the Oregon File Guidelines is the easiest way to keep files in this location.

Step 4

Check whether the top file angle should be parallel to the center line of the chain saw chain.

Step 5

Locate the most damaged paper cutter. Use stable, uniform strokes ("full file length") for sharpening to eliminate damage, while counting the number of file strokes.

You will know that when the surface of the cutter is silvery glossy, the damage will be eliminated. File all cutters with the same number of strokes from the inside to the outside so that the cutter lengths are equal.

Step 6

Before turning the chain to the switch side, complete all the tools on the side of the chain.

File from the inside of each cutter to the outside. Finish all knives on one side of the chain. When finished, rotate the saw to repeat the process for the other side of the chain. Remember to keep all cutters the same length.

Step 7

Return to eliminate damage and keep the top plate equal in length.

Step 8

Recheck the depth gauge.

Step by step: How to sharpen a chainsaw chain with an Oregon electric knife sharpener

These instructions are only general guidelines. For setup usage and instructions, please refer to your grinder manual.

Polish your chain to meet the manufacturer's recommendations. Use rapid tapping movements to minimize overheating of the ground.

step 1

Check the shape of the grinding wheel.

Step 2

Set the vise assembly to the correct top file angle.

Please refer to your grinder manual for the best way to do this.

Step 3

Use the recommended cutting angle of the top plate to set a proper angle of the grinding head.

Step 4

Check whether the vise locking handle is tightened and the chain is locked.

Step 5

Turn on the electric sharpener.

Step 6

Lower the arm motor unit to make the cutter sharp.

Step 7

After sharpening the cutter, raise the arm and release the handle.

Step 8

Slide the chain forward to locate the next knife to be sharpened.

Step 9

Block it again with the handle and sharpen it.

Step 10

When all the cutters are sharpened, turn off the machine and unplug the power cord.

Step 11

Regular dressing of the vitrified grinding wheel to maintain the correct shape.

Use a rotary trimmer or trim tiles.

Step by step: what to do after sharpening the chainsaw chain

step 1

Use the instructions here to check and adjust the depth gauge.

Step 2

Remove all debris, and then thoroughly lubricate the chain with chain and chain oil. For best results, soak the chain overnight.

Step 3

Store the sharpened saw chain in a container with lubricant for next use.
