WARNING
• When the engine is overheated, do not
remove the radiator cap, as the heated
water will splash out, resulting in scald.
• If any of the lights shown in the figure
above are lit while operating, stop using
the machine, and inspect as needed. (Refer
to Chapter 4 “Part Names and Functions.”)
NOTICE
Before rotating the boom for the first time
at the start of work, or during checks,
make sure that the rotation lock pin is
unlocked. (See figure below.)

NOTICE
• Immediately release your hand from the
engine start switch once the engine has
started.
• Do not hold the engine start switch up for
15 seconds or more. Failure to release your
hand could result in damage to the starter
motor.
• Take an interval of 30 seconds or more
before re-starting the engine to prevent
damaging the engine.
After starting engine, idle the engine for about
5 minutes for warming up.
NOTICE
If the outside air temperature is below the
temperature range for the hydraulic oil
used in the machine, travel the machine
in a warm place until the hydraulic oil is
warm enough, and then do the outside
work.
Check the fuel level light.
When there is little fuel remaining, this light
will be lit. (On a level surface, the fuel level light
goes on at about 20 liters.)
