6 IMPORTANT SAFETY INSTRUCTIONS

components may no longer function properly and safety 

devices may be inoperative. To reduce the risk of personal 

injury and property damage:

– Take the chain saw and battery to your authorized 

STIHL servicing dealer to be checked before further 

operation.

■ Genuine STIHL replacement parts are specifically 

designed to match your chain saw and meet safety and 

performance requirements. Use of parts that are not 

authorized or approved by STIHL may cause serious or 

fatal injury or property damage.

– STIHL recommends that only identical STIHL 

replacement parts be used.

6.5 Using the Chain Saw

6.5.1 Before Operation

WARNING

■ Misuse or unauthorized use may result in personal injury 

and property damage.

– Use the chain saw only as described in this 

instruction manual.

■ For proper assembly of the bar and chain:

– Read and follow the instructions on mounting the 

guide bar and saw chain, 

@

15.2.1

■ The saw chain, guide bar and sprocket must match each 

other in gauge and pitch. Before mounting or replacing:

– Read the information on guide bar and saw chain 

combinations, 

@

27.

– Read and follow the instructions on kickback and 

other reactive forces, 

@

7.

– Select the shortest bar that will meet your cutting 

needs. Longer bars add weight and may be more 

difficult to control.

■ Proper tension of the saw chain is extremely important to 

maximize cutting performance and reduce the risk of 

personal injury from chain breakage, derailment or 

reactive forces:

– Read and follow the chain tensioning instructions, 

@

15.3.

– Always make sure the chain sprocket cover is 

tightened securely after tensioning the saw chain in 

order to secure the bar. Never start the chain saw 

with the chain sprocket cover loose or missing.

– Check saw chain tension once more after tightening 

the chain sprocket cover.

– After adjusting the saw chain, let the motor run for a 

minute or two, then switch the motor off and engage 

the chain brake. Remove the battery and recheck 

chain tension.

– Check saw chain tension periodically thereafter at 

regular intervals (only after engaging the chain brake 

and removing the battery).

– Never cut with a loose chain. If the saw chain 

becomes loose while cutting, switch off the motor, 

engage the chain brake and remove the battery from 

the chain saw before tightening the chain. Never 

attempt to adjust the saw chain while the battery is 

inserted.

■ Using a chain saw that is damaged, improperly adjusted 

or maintained, or not completely and securely assembled 

can lead to a malfunction and increase the risk of serious 

personal injury or death.

– Never operate a chain saw that is damaged, 

improperly maintained or not completely and 

securely assembled.

– Always check your chain saw for proper condition 

and operation before starting work, particularly the 

trigger switch, trigger switch lockout, front hand 

guard, chain brake and cutting attachment.
