6. GENERAL PRECAUTIONS
 WARNING: Failure to follow these safety precautions may lead
to a serious accident.
UNAUTHORIZED MODIFICATION
‡ Any modification made without authorization from Komatsu can create hazards.
‡ Before making a modification, consult your Komatsu distributor. Komatsu will not be responsible
for any injury or damage caused by any unauthorized modification.
ALWAYS APPLY LOCK WHEN LEAVING OPERATOR’S SEAT
‡ When standing up from the operator’s seat, always place the safety lock lever securely in the LOCK
position. If you accidentally touch the travel or swing lever when they are not locked, the work
equipment may suddenly move and cause serious injury or damage.
‡ When leaving the machine, lower the work equipment completely to the ground, set the safety
lock lever to the LOCK position, then stop the engine and use the key to lock all the equipment.
Always take the key with you.
