SAFETY
• Fasten the seatbelt. When the brakes are applied sudden-
ly, the operator may be thrown out of the operator's seat. It
is dangerous and may cause personal injury.
• Check that the movement of the machine matches the dis-
play on the control pattern card.
If it does not match, replace it immediately with the correct
control pattern card.
• Check the operating condition of the machine, work equip-
ment, and travel and swing systems.
• Check for any problem in the sound, vibration, heat and
smell of the machine, or abnormalities of instruments. Also
check that there is no leakage of oil or fuel.
• If any problem is found, repair it immediately.
PRECAUTIONS WHEN TRAVELING IN FORWARD OR REVERSE AND SWINGING
• When driving the machine, drive with sprocket (1) at the
rear of the machine. If sprocket (1) is at the front, the oper-
ation of the travel levers will be the opposite of the actual
direction of travel, so there is a hazard that the machine
may travel in an unexpected direction, leading to serious
injury or death.
• Always lock all the doors and windows of the operator's
compartment in position regardless of whether it is open or
closed.
Always close all the windows and doors on jobsites where
there is danger of scattering fragments, and things which
may intrude into operator's cab.
• Prohibit anyone other than the operator to get on the machine
• If there are any people in the area around the machine, there is danger that they may be hit or caught by
the machine, and this may lead to serious personal injury or death. Before starting travel or swing, be sure
to observe the following.
• Always operate the machine only when seated on the
operator's seat.
• Before starting to move, check again that there is no
people or obstacle in the surrounding area.
• Before moving, sound the horn to warn people in the
surrounding area.
• Check that the travel alarm and other alarms work
properly.
• If there is an area in the rear of the machine which
cannot be seen, position a signalman. Be extremely
careful not to hit any people or object, and drive or
swing slowly.
Observe the above mentioned precautions although the mirror
is installed.
