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 battery is inserted. Never

6.5.2. Keep bystanders out of the area while
testing the controls.
To test the controls:
► Remove the battery.
► Attempt to depress the trigger switch.
If the trigger switch 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.
► Press down on the trigger switch lockout and retaining
button. Make sure they move freely and spring back into
place when released.
► Insert the battery.
► Hold the chain saw firmly with both hands, your left hand
on the front handle and your right hand on the rear handle.
Depress and hold the trigger switch lockout, press the
retaining button with your thumb and squeeze the trigger
switch with your index finger.
The chain saw should switch on. If it does not, take the
chain saw to an authorized STIHL servicing dealer to be
repaired before use.
► Release the trigger switch.
The chain saw should switch off.
If the chain saw does not switch off after you release the
trigger switch, remove the battery and take the chain saw
to an authorized STIHL servicing dealer to be repaired
before use.
18.3 Testing 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:
► Insert the battery,
► Disengage the chain brake,
► Point the guide bar toward a bright surface.
► Switch on the chain saw,
The chain should throw off a small amount of oil.
If the chain oil cannot be seen, check the oil level and refill
the tank as necessary.
► Test the chain lubrication again.
► If chain lubrication oil is still not visible, the lubrication
mechanism is not functioning. Take the saw to an
authorized STIHL servicing dealer to be repaired before
use.
19.1 Selecting the Power Level
When using the STIHL AP 500 S battery, the saw can be
operated at three different power settings, indicated by
