cutting tip, the depth gauge setting between the tip and the side plate ridge will decrease. To maintain
FR
optimal cutting performance, the ridge has to be filed down to achieve the recommended depth gauge
setting.
ES
To sharpen the chain :
1. Using protective gloves, ensure the chain is correctly tensioned on the guide bar.
PT
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
IT
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
EL
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
PL
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
RU
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.
KZ
• 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.
Replacing the saw chain and chain bar
UA
Approved saw bar/saw chain
Replace chain when cutters are too worn to sharpen or when chain breaks. Only use replacement chain
RO
noted in this manual.
Always include new drive sprocket when replacing chain. This will maintain proper driving of chain.
1. Place the saw body on a firm and level surface.
BR
2. Rotate the bar adjust locking knob anticlockwise to remove the cover from the saw's body.
3. Wearing protective gloves, wrap the saw chain around the chain bar, making sure that the teeth are
aimed in the direction of rotation. The chain should be properly set in the slot running along the entire
EN
outside edge of the chain bar.
4. Place the saw chain around the sprocket) while lining up the slot in the chain bar with the internal bolt
at the base of the saw and the chain tensioning pin in the chain bar's pin hole. The chain tensioning pin
may need adjustment to properly align with the hole in the chain bar. Use the chain tensioning wheel to
adjust its location until it fits in the chain bar.
5. Turn the chain tensioning wheel to preliminarily tighten the chain bar enough that it stays in place.
While holding the bar still, place the cover back onto the saw. Make sure the tab properly lines up with the
slot on the body of the saw. Lock the cover in place with the cover locking knob by turning it clockwise
until it engages. Adjust the chain tension.
