PRECAUTIONS FOR OPERATION SAFETY
DO NOT GO CLOSE TO HIGH-VOLTAGE CABLES
Do not travel or operate the machine near electric cables. There is
a hazard of electric shock, which may cause serious personal
injury or death. On jobsites where the machine may go close to
electric cables, always do as follows.
Before starting work near electric cables, inform the local power
company of the work to be performed, and ask them to take the
necessary action.
Even going close to high-voltage cables can cause electric
shock, which may cause serious burns or even death. Always
Voltage of Cables Safety Distance
maintain a safe distance (see the table on the right) between the 100V - 200V Over 2 m (7 ft)
machine and the electric cable. Check with the local power 6,600V Over 2 m (7 ft)
company about safe operating procedure before starting 22,000V Over 3 m (10 ft)
operations. 66,000V Over 4 m (14 ft)
To prepare for any possible emergencies, wear rubber shoes 154,000V Over 5 m (17 ft)
and gloves. Lay a rubber sheet on top of the seat, and be careful
187,000V Over 6 m (20 ft)
not to touch the chassis with any exposed part of your body.
275,000V Over 7 m (23 ft)
Use a signalman to give warning if the machine approaches too
close to the electric cables. 500,000V Over 11 m (36 ft)
When carrying out operations near high voltage cables, do not
let anyone near the machine.
If the machine should come too close or touch the electric cable,
to prevent electric shock, the operator should not leave the
operator's compartment until it has been confirmed that the
electricity has been shut off.
Also, do not let anyone near the machine.
ENSURE GOOD VISIBILITY
This machine is equipped with mirrors to ensure good visibility, but even then there are places that cannot be seen
from the operator's seat, so be careful when operating.
When traveling or carrying out operations in places with poor visibility, it is impossible to check for obstacles in the
area around the machine and to check the condition of the jobsite. This leads to danger of serious personal injury
or death. When traveling or carrying out operations in places with poor visibility, always observe the following.
Position a signalman if there are areas where the visibility is not good.
Only one signalman should give signals.
When working in dark places, turn on the working lamp and front lamps installed to the machine, and set up
additional lighting in the work area if necessary.
Stop operations if the visibility is poor, such as in mist, snow, rain, or dust.
When checking the mirrors installed to the machine, remove all dirt and adjust the angle of the mirror to ensure
good visibility.

RECOMMENDED FUEL, COOLANT, AND LUBRICANT MAINTENANCE
RECOMMENDED FUEL, COOLANT, AND LUBRICANT
Komatsu genuine oils are adjusted to maintain the reliability and durability of Komatsu construction equipment
and components.
In order to keep your machine in the best conditioner for long periods of time, it is essential to follow the
instructions in this Operation and Maintenance Manual.
Failure to follow these recommendations may result in shortened life or excess wear of the engine, power train,
cooling system, and/or other components.
Commercially available lubricant additives may be good for the machine, but they may also cause harm.
Komatsu does not recommend any commercially available lubricant additive.
Use the oil recommended according to the ambient temperature in the chart below.
Specified capacity means the total amount of oil including the oil in the tank and the piping. Refill capacity means
the amount of oil needed to refill the system during inspection and maintenance.
When starting the engine in temperatures below 0°C (32°F), be sure to use the recommended multi-grade oil,
even if the ambient temperature may become higher during the course of the day.
If the machine is operated at a temperature below -20°C (-4°F), a separate device is needed, so consult your
Komatsu distributor.
When the fuel sulfur content is less than 0.2%, change the engine oil according to the period inspection table
given in this Operation and Maintenance Manual.
If the fuel sulfur content is more than 0.2%, change the oil according to the following table.
Sulfur content (%) Oil change interval
Less than 0.2 % 500 hours
0.2 to 0.5 % 250 hours
0.5 and up Not recommendable (*)
* If these fuels are used, there is danger that serious trouble may occur because of early deterioration of the engine
oil or early wear of the internal parts of the engine. If the local situation makes it necessary to use these fuels,
always remember the following.
1) Be sure to check Total Basic Number (TBN) of oil frequently by TBN handy checker etc., and change oil
based on the result.
2) Always be aware that oil change interval is extremely shorter than standard.
3) Be sure to carry out periodic engine inspection by distributor's expert since change interval of periodic
replacement parts and overhaul interval are also shorter.
