MAINTENANCE PROCEDURE
• It is dangerous if the work equipment moves by mistake when the tooth is being replaced.
Set the work equipment in a stable condition, set the lock lever securely to LOCK position, and stop
the engine.
• Broken pieces may fly during the replacement work, so always wear the protective equipment such
as protective eyeglasses and gloves.
• If the tooth pin cannot be removed by this method, ask your Komatsu distributor to have the re-
placement performed for safety.
• As the pin is driven out with strong force, it is dangerous that the pin may fly out. Check that there
is no people around the machine.
• Provide a socket wrench of 14 mm width.
