GENERAL SPECIFICATION AND TECHNICAL DATA
PC200LC-8 01-9
Remark
Always use diesel oil for the fuel.
To ensure good fuel consumption characteristics and exhaust gas characteristics, the engine mounted on this
machine uses an electronically controlled high-pressure fuel injection device. This device requires high
precision parts and lubrication, so if low viscosity fuel with low lubricating ability is used, the durability may drop
markedly.
Note 1: Power train oil has different properties from engine oil. Be sure to use the recommended oils.
Note 2: Hyper white grease (G2-TE) has a high performance.
When it is necessary to improve the lubricating ability of the grease in order to prevent squeaking of pins and
bushings, the use of G2-TE is recommended.
Note. 3: Supercoolant (AF-NAC)
1. The coolant has the important function of preventing corrosion as well as preventing freezing.
Even in the areas where freezing is not an issue, the use of antifreeze coolant is essential.
Komatsu machines are supplied with Komatsu Supercoolant (AF-NAC). Komatsu Supercoolant (AF-NAC) has excellent
anticorrosion, antifreeze and cooling properties and can be used continuously for two years or 4000 hours.
Komatsu Supercoolant (AF-NAC) is
strongly recommended wherever available.
2. For details of the ratio when diluting super coolant with water, see "Clean Inside of Cooling System" in Section 3 of the
OMM.
3. When the machine is shipped from the factory, it may be filled with coolant containing 30% or more Supercoolant
(AF-NAC). In this case, no adjustment is needed for temperatures down to -10°C (14°F). (never dilute with water)
4. To maintain the anticorrosion properties of Supercoolant (AF-NAC), always keep the density of Supercoolant between
30% and 68%.
