Shutting Off The Engine; Checking The Chain Saw; Checking The Operation Of The Chain Brake - Stihl MS 500i Instruction Manual

English
► Pull the starter grip quickly and allow the starter rope to
rewind several times until the engine runs.
► Do not pull out the starter rope to full length and do not let
the starter grip snap back. Guide it slowly back into the
housing so that the starter rope can rewind properly.
► Disengage the chain brake, @ 12.2.
Your chain saw is ready for operation.
► If the saw chain rotates when the engine is idling, shut off
the engine, engage the chain brake and have the chain
saw inspected by an authorized STIHL servicing dealer
before further use.
NOTICE
Accelerating the engine while the chain brake is engaged or
the chain is otherwise blocked (i.e., not able to turn)
increases the load and will cause the clutch to slip
continuously. This may occur if the throttle is depressed for
more than a few seconds when the chain is pinched in the
cut or the chain brake is engaged. To reduce the risk of
overheating and damage to important components (e. g.
clutch, polymer housing components), always disengage the
chain brake before accelerating engine and before starting
cutting work. The only exception to this rule is when you
check operation of the chain brake, @ 16.1.

15 Shutting Off the Engine

15.1 Shutting Off the Engine
WARNING
The saw chain will continue to rotate for a short while after
the throttle trigger is released. To avoid serious or fatal
injury, avoid contact with the moving chain. To reduce the
risk of personal injury from unintended activation or
unauthorized use, shut off the engine, ensure the chain has
stopped and engage the chain brake before walking with the
saw or setting it down.

To shut off the engine:
1
► Release the throttle trigger (2).
The engine settles down to idle speed.
► Depress the stop switch (1).

16 Checking the Chain Saw

16.1 Checking the Operation of the Chain Brake

WARNING
Operating the saw with a missing, damaged, modified or
improperly maintained chain brake increases the risk of
severe or fatal injury from kickback. Never attempt to modify
or disable the chain brake. Never operate a saw if the chain
brake has been modified or does not function properly. If you
detect a change in the operating characteristics of the chain
brake, have your saw serviced immediately by an authorized
STIHL servicing dealer.
Before starting work, check the operation of the chain brake:
► Run the engine at idle speed.
► Engage the chain brake, @ 12.1.
► Accelerate up to full throttle for no more than 3 seconds.
A properly functioning chain brake prevents the chain from
rotating.
► If the chain brake fails to prevent the chain from rotating,
have the saw inspected and repaired by an authorized
STIHL servicing dealer.
