FOREWORD
Before starting any maintenance operation, position the machine on a firm and level surface, lower the
equipment to the ground, engage the safety locks of the equipment and the controls, and stop the engine.
To make the information clearer, some illustrations in this manual represent the machine without safety
guards. Do not use the machine without guards and do not start the engine when the hood is open, unless
this is expressly prescribed for certain maintenance operations.
It is strictly forbidden to modify the setting of the hydraulic system safety valves; Komatsu cannot be held
liable for any damage to persons, property or the machine, if this has been tampered with by modifying
the standard settings of the hydraulic system.
Before carrying out any electric welding, disconnect the battery and the alternator. (See "PRECAUTIONS
CONCERNING THE BATTERY AND THE ALTERNATOR (2-58)").
Install only optional tools or tools especially recommended and approved by Komatsu and that meet the
requirements included in section "EQUIPMENT CONFIGURATION (6-5)"
It is absolutely forbidden to operate the machine while standing on the ground.
Every single manoeuvre must be carried out by the operator, correctly seated in driving position.
