WARNING! When handling saw chains, always wear protective

gloves.

Checking the automatic chain lubrication

Regularly check the functionality of the automatic chain lubrication in order to prevent overheating and

the subsequent damage to the chain bar and saw chain associated with it. For this purpose, align the

chain bar tip against a smooth surface (board, cut-in of a tree) and allow the chain saw to run. If an

increasing amount of oil appears, the automatic chain lubrication functions properly.

Lubricate sprocket

NOTE :

It is not necessary to remove the chain or bar when lubricating the sprocket.

1. Clean the bar and sprocket.
2. Using a grease gun, insert the tip of the gun into the lubrication hole and inject grease until it appears

at the outside edge of the sprocket tip.
3. To rotate the sprocket release the chain stop and pull the chain by hand until the ungreased side of the

sprocket is in line with the grease hole. Repeat the lubrication procedure.

Sharpening the saw chain

Keep chain sharp. Your saw will cut faster and more safely. A dull chain will cause undue sprocket, guide

bar, chain, and motor wear. If you must force chain into wood and cutting creates only sawdust with

a few large chips, then chain is dull. Purchase a new chain, have your chain sharpened professionally

at a qualified service center, or sharpen the chain yourself using a proper sharpening kit. The height

difference between the cutting tip and the ridge is the depth gauge setting. When you sharpen the

cutting tip, the depth gauge setting between the tip and the side plate ridge will decrease. To maintain

optimal cutting performance, the ridge has to be fi led down to achieve the recommended depth gauge

setting.

To sharpen the chain :

1. Using protective gloves, ensure the chain is correctly tensioned on the guide bar.
2. Use a round file with a diameter 1.1 times the cutting tooth depth. Make sure 20% of the file diameter

is above the cutter’s top plate.

NOTE:

A file guide is available from most chainsaw retailers and is the easiest way to hold the file at the

correct position.
3. File at an angle perpendicular to the bar, and at an angle of 25° to the direction of travel.
4. File each tooth from the inside towards outside only. File one side of the chain first then turn the saw

around and repeat the process.
• Sharpen each tooth equally by using the same number of strokes.
• Keep all cutter lengths equal. Each time the cutting tip is sharpened the cutting length is reduced. When

the cutter length is reduced to 0.16 inch (4 mm), the chain is worn out and should be replaced.
• The depth gauge setting is also reduced with each sharpening. Every 5 sharpenings use a depth gauge

measuring tool to check the height between the cutting tip and the ridge. When necessary, use a flat file

to file down the ridge to achieve the .025 inch depth gauge setting. Depth gauge measuring tools are

available from most chainsaws retailers.
• If the saw is not functioning properly, take it to a qualified chainsaw service center to have the saw

inspected. Use only identical parts as listed in this manual.
