Trigger Switch Lockout (1) and Trigger Switch (2)
WARNING
To reduce the risk of serious or fatal injuries, keep hands,
feet and other parts of the body away from the chain. Do not
touch the saw chain while the chain saw is connected to the
power supply. Never touch a moving chain with your hand or
any part of your body, @ 5.6.2. Keep bystanders out of the
area while testing the controls.
To test the controls:
► Disconnect the chain saw from the power supply.
► Attempt to depress the trigger switch.
If the trigger can be depressed without first depressing the
trigger switch lockout, take the chain saw to an authorized
STIHL servicing dealer to be repaired before use.
► Connect the chain saw to the power supply and hold it
firmly with both hands, your left hand on the front handle
and your right hand on the rear handle. Release the chain
brake and switch on the chain saw by depressing the
trigger switch and trigger switch lockout.
If the chain does not start rotating, engage the chain brake
and disconnect the chain saw from the power supply.
Take the chain saw to an authorized STIHL servicing
dealer to be repaired before use.

14.3 Testing Saw Chain Lubrication

WARNING
Never operate your saw without bar and chain lubrication. If
the chain runs dry, the cutting attachment will be damaged
beyond repair within a very short time. A damaged chain
may break, resulting in severe or fatal personal injury.
Always check chain lubrication and the oil level in the tank
before starting work and periodically during work.
To confirm that the chain oil is flowing properly:
1
► Check the oil sight glass.
► If the oil level reads below the marking "OIL min" (1), refill
the oil tank with chain oil.
► Connect the chain saw to the power supply.
► Disengage the chain brake, @ 11.2.
► Point the guide bar toward a bright surface.
