English 21.2 Inspecting and Maintaining the Chain Saw 21 Inspection and Maintenance WARNING ■ To reduce the risk of personal injury from unin‐ tended activation, shut off the engine and engage the chain brake before inspecting the chain saw or carrying out any maintenance, 8. Carry out only the maintenance operations described in this manual. There are no userauthorized repairs. STIHL recommends that repair work be performed by authorized STIHL servicing dealers. Proper maintenance of the chain saw includes the following activities: ► Installing a new spark plug after approximately 100 operating hours or earlier if the electrodes are badly eroded or corroded. ► Having the spark arresting screen inspected and cleaned according to the maintenance chart. ► Inspecting the chain sprocket periodically and having a worn chain sprocket replaced by an authorized STIHL servicing dealer. ► Inspecting the guide bar for proper groove depth and spread and replacing the guide bar if it shows signs of excessive wear or damage. ► Periodically sharpening the chain, maintaining the depth limiting guides at the appropriate height and replacing the saw chain when indi‐ cated by the relevant wear marks or when the chain is damaged or shows signs of excessive wear. ► Having worn, missing or damaged safety labels replaced by an authorized STIHL serv‐ icing dealer. If you make a warranty claim for a component that has not been serviced or maintained prop‐ erly, coverage may be denied. 21.3 Inspecting and Maintaining the Chain Sprocket ► Shut off the engine and engage the chain brake. ► Remove the chain sprocket cover, saw chain and guide bar. a ► Check the chain sprocket cover for wear marks. ► If the wear marks are deeper than a = 0.020 in. (0.5 mm), have the chain sprocket replaced. STIHL recommends using genuine STIHL chain sprockets to ensure optimal functioning of the chain brake. Alternating between two chains helps reduce wear to the chain sprocket. 21.4 Inspecting and Maintaining the Guide Bar ► Shut off the engine and engage the chain brake. ► Remove the guide bar and saw chain, 10.2. ► Measure the depth of the guide bar groove in the area with the greatest wear using the measuring tool on the file gauge sold sepa‐ rately. ► Replace the guide bar if the measured depth is less than the required minimum depths sta‐ ted in 23.4. ► Check the spread of the guide bar groove with the measuring tool on the file gauge. ► Replace the guide bar if the groove is nar‐ rowed, spread or shows other signs of sub‐ stantial wear or damage.

Inspecting and Maintaining the

Chain Saw

WARNING

■

To reduce the risk of personal injury from unin‐

tended activation, shut off the engine and

engage the chain brake before inspecting the

chain saw or carrying out any maintenance,

8. Carry out only the maintenance operations

described in this manual. There are no user-

authorized repairs. STIHL recommends that

repair work be performed by authorized STIHL

servicing dealers.

Proper maintenance of the chain saw includes

the following activities:

►

Installing a new spark plug after approximately

100 operating hours or earlier if the electrodes

are badly eroded or corroded.

►

Having the spark arresting screen inspected

and cleaned according to the maintenance

chart.

►

Inspecting the chain sprocket periodically and

having a worn chain sprocket replaced by an

authorized STIHL servicing dealer.

►

Inspecting the guide bar for proper groove

depth and spread and replacing the guide bar

if it shows signs of excessive wear or damage.

►

Periodically sharpening the chain, maintaining

the depth limiting guides at the appropriate

height and replacing the saw chain when indi‐

cated by the relevant wear marks or when the

chain is damaged or shows signs of excessive

wear.

►

Having worn, missing or damaged safety

labels replaced by an authorized STIHL serv‐

icing dealer.

If you make a warranty claim for a component

that has not been serviced or maintained prop‐

erly, coverage may be denied.

21.3

Inspecting and Maintaining the

Chain Sprocket

►

Shut off the engine and engage the chain

brake.

►

Remove the chain sprocket cover, saw chain

and guide bar.

0000-GXX-1216-A0

►

Check the chain sprocket cover for wear

marks.

►

If the wear marks are deeper than

a = 0.020 in. (0.5 mm), have the chain

sprocket replaced.

STIHL recommends using genuine STIHL chain

sprockets to ensure optimal functioning of the

chain brake.

Alternating between two chains helps reduce

wear to the chain sprocket.

21.4

Inspecting and Maintaining the

Guide Bar

►

Shut off the engine and engage the chain

brake.

►

Remove the guide bar and saw chain,

10.2.

0000-GXX-1217-A0

►

Measure the depth of the guide bar groove in

the area with the greatest wear using the

measuring tool on the file gauge sold sepa‐

rately.

►

Replace the guide bar if the measured depth

is less than the required minimum depths sta‐

ted in

23.4.

►

Check the spread of the guide bar groove with

the measuring tool on the file gauge.

►

Replace the guide bar if the groove is nar‐

rowed, spread or shows other signs of sub‐

stantial wear or damage.
