Pay particular attention to the following points
during the run-in period.
After starting the engine, let it idle for 5
minutes to warm up.
Avoid work with heavy loads or at high speed.
Avoid sudden starting off, rapid acceleration,
unnecessary sudden stops, and severe
changes in direction.
Specified Applications
Use this product mainly for the following
applications.

Explanation of Main Parts
The "SH145X-6/SH145XU-6" are hydraulic excavators.
The hydraulic excavator comprises the undercarriage with shoes mounted, the upper swing body, and
the turntable bearing that supports the upper swing body.
The upper swing body includes the attachments at the tip of the machine, the engine, the hydraulic
equipment, and the cab.
The hydraulic excavator is operated by the fluid sent by the engine drive pump.
The fluid sent to the control valves is distributed by the cylinders and hydraulic motors to operate the
attachments.
The machine is also equipped with a cooling system to hold the fluid at a certain temperature.
