Preparations At The Workplace; Two-Stroke Oil - Hilti DSH 700 Serie Manual Del Usuario

The data given represents the main applications of the machine. However, if the machine is used for different
applications, with different accessory tools or is poorly maintained, the data may vary. This may significantly
increase exposure over the total working period.
An accurate estimation of exposure should also take into account the times when the machine is switched
off, or when it is running but not actually being used for a job. This may significantly reduce exposure over
the total working period.
Identify additional safety measures to protect the operator from the effects of noise and/or vibration, for
example: Maintaining the machine and accessory tools, keeping the hands warm and organizing work
patterns.

Preparations at the workplace

5.1 Fuel
The two-stroke engine runs on a mixture of gasoline and oil. The quality of the fuel mixture decisively
influences operation and life expectancy of the engine.
WARNING
Risk of injury. The inhalation of gasoline vapors and skin contact with gasoline may be hazardous to the
health.
▶ Avoid direct skin contact with gasoline. Wear protective gloves.
▶ If your clothing becomes soiled with gasoline, it is essential to change your clothing.
▶ Ensure that the workplace is well ventilated in order to avoid breathing in gasoline fumes.
▶ Use a fuel container that complies with the applicable regulations.
5.1.1 Gasoline
▶ Use regular or super gasoline with an octane rating of at least 89 ROZ.
The alcohol content (e.g. ethanol, methanol or others) of the fuel used must not exceed 10%,
otherwise the life expectancy of the engine will be greatly reduced.
5.1.2

Two-stroke oil

▶ Use good-quality two-stroke oil for air-cooled engines that meets at least the API TC specification.
