NOTE:
The two fastening nuts (
11
) must be loosened before
tightening the V-belt or checking the tension.
To increase the belt tension, turn the tightening screw (
12
) to
the right (clockwise) with the combination wrench included with
the Power Cut.
The belt tension is correctly adjusted when the nut (
13
) is cen-
tred on the mark (
14
).
IMPORTANT:
After tightening/inspection, make certain to tighten
the fastening nuts (
11
) (30 ± 2 Nm).
Tightening the V-belt /
Checking V-belt tension
IMPORTANT
:
Exact V-belt tension is essential for maximum cutting per-
formance with minimum fuel consumption. Improper V-belt
tension will result in premature wear to the V-belt and V-belt
wheel or damage to the clutch bearing.
If the Power Cut is new or the V-belt has been replaced,
retighten the V-belt after the
Þ
rst hour of operation!
Fuels
Caution:
The Power Cut uses mineral-oil products
(gasoline and
oil)
.
Be especially careful when handling gasoline.
Do not smoke. Do not allow gasoline to come near
ß
ames,
sparks or
Þ
re (explosion hazard).
Fuel mixture
The Power Cut is powered by a high-performance two-stroke
engine. It runs on a mixture of gasoline and two-stroke engine
oil.
The engine is designed for unleaded regular gasoline with a
min. octane value of 91 ROZ. In case no such fuel is available,
you can use fuel with a higher octane value. This will not affect
the engine.
In order to obtain an optimum engine output and to protect
your health and the environment use unleaded fuel only.
To lubricate the engine, use a two-stroke engine oil (quality grade
JASO FC or ISO EGD), which is added to the fuel. The engine
is designed for the use of DOLMAR HP 100 high-performance
two-stroke engine oil at a mixture ratio of only 100:1 to protect
the environment. In addition, this ensures a long service life and
reliable operation with minimum exhaust emissions.
