If there is any problem with your machine, repair it before

IMPORTANT:
Use only recommended fuel and lubricants.
Be sure to use only genuine Hitachi parts. Failure to

machine breakdown.
Failure to use recommended fuel, lubricants, and
genuine Hitachi parts will result in loss of Hitachi
product warranty.
Never adjust engine governor or hydraulic system
relief valve.
Protect electrical parts from water and steam.
Never spray high pressure water or steam to the
transmission oil filler port and vicinity of the axle air

Never disassemble electrical components such as

Using bad quality fuel, drainage agent, fuel
