Fuel/Refueling - Dolmar MH-2556 Handbuch

FUEL/REFUELING

Gasoline/oil mixture
- The engine of the pole hedge trimmer is a highly efficient two-stroke engine that
runs on a mixture of gasoline and two-stroke engine oil. The engine is designed
to use regular unleaded gasoline with a min. octane value of 91 ROZ. If such
gasoline is not obtainable, instead use gasoline with the highest octane value
available. This will not cause any damage to the engine, but may result in poor
engine performance. Similar results are to be expected when leaded gasoline is
used. To obtain optimal engine performance, and for the sake of human health
and the environment, where possible use unleaded fuel.
- Two-stroke engine oil (quality grade: TSC-3) must be added to the gasoline in
order to lubricate the engine. The engine has been designed to use environment-
friendly DOLMAR 2-stroke oil, which is to be mixed at a ratio of 50:1. This
specially developed oil ensures prolonged engine service life and reliable engine
performance with an absolute minimum of exhaust gas emissions. It is imperative
to strictly observe the 50:1 mixture (Gasoline/DOLMAR 2-stroke oil), as reliable
performance of the pole hedge trimmer cannot be guaranteed otherwise.
- Correct gasoline/oil mixture:
Mix 50 parts gasoline with 1 part DOLMAR 2-stroke engine oil (see also table on
the right).
NOTE: When preparing the gasoline/oil mixture, first mix all of the amount of oil
required with half the amount of gasoline required. Add the remaining
gasoline and shake the mixture well before replenishing the tank.
Do not add more oil then prescribed. If too much oil is added this will
produce additional combustion residue, thus polluting the environment and
clogging the muffler and the cylinder exhaust channel. In addition, overall
fuel consumption will also increase and poorer engine performance is to
be expected.
Handling of petroleum products
Always handle fuel with the utmost care and attention. Since fuel contains
substances similar to solvents, refueling must be done outdoors or in well-
ventilated areas. Do not inhale gasoline fumes and avoid any skin contact with
gasoline or oil. Human skin will dry out if in contact with petroleum over an
extended period of time. This may result in various skin diseases and allergic
reactions.
Gasoline or oil coming into contact with the eyes can cause severe eye irritation.
Should gasoline or oil come into contact with your eyes, immediately rinse your
eyes with large amounts of clean water. Do not hesitate to see a doctor if irritation
persists.
Refueling
The engine must be switched off.
- Thoroughly clean the area around the fuel filler cap (2), to prevent dirt from
getting into the fuel tank (1).
- Unscrew the fuel filler cap (2) and fill the tank with fuel.
- Tightly screw on the fuel filler cap (2).
- Clean screw fuel filler cap (2) and tank after refueling.
Fuel storage
- Fuel deteriorates if stored over an extended period of time.
- Purchase only the amount of fuel to be used over a 4-week period.
- Use only approved petroleum-storage containers.
