Chain Brake; Fuels / Refuelling; Fuel Mixture - Dolmar PS-33 Instructions D'emploi

Chain brake

A
The DOLMAR models comes with an inertia chain brake as
standard equipment. If kickback occurs due to contact of the
guide-bar tip with wood (see SAFETY PRECAUTIONS, page
6), the chain brake will stop the chain through inertia if the
kickback is sufficiently strong. The chain will stop within a
fraction of a second.
The chain brake is installed to block the saw chain before
starting it and to stop it immediately in case of an
emergency.
IMPORTANT: NEVER run the saw with the chain brake
activated (except for testing, see "Checking the chain brake")!
Doing so can very quickly cause extensive engine
damage!
ALWAYS release the chain brake before starting
the work!

Fuel mixture

The engine of the chain saw is a high-efficiency 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.
For lubricating the engine use a two-stroke engine oil (quality
grade: API-TC), which is added to the fuel. The engine has
been designed for use of DOLMAR HP 100 high-performance
two-stroke engine oil and a mixture ratio of only 100:1 to protect
the environment. In addition, a long service life and reliable
operation with a minimum emission of exhaust gases are
ensured.

Engaging the chain brake (braking)
If the kickback is strong enough the sudden acceleration of the
guide bar combined with the inertia of the hand guard (B/3)
will automatically actuate the chain brake.
To engage the chain brake manually, simply push the hand
guard (B/3) forward (towards the tip of the saw) with your left
hand (arrow 1).
Releasing the chain brake
Pull the hand guard (B/3) towards you (arrow 2) until you feel
it catch. The brake is now released.
DOLMAR HP 100 high-performance two-stroke engine oil is
available in the following sizes:
0.5
DOLMAR high-performance two-stroke engine oil is available
in the following sizes to suit your individual requirements:
1
100 ml
In case DOLMAR high-performance two-stroke engine oil is
not available, it is urgently recommended to use a mixture ratio
of 40:1 with other two-stroke engine oils, as otherwise optimum
operation of the engine cannot be guaranteed.
The correct mixture ratio:

50:1 when using DOLMAR high-performance two-stroke en-
gine oil, i. e. mix 50 parts gasoline with 1 part oil.
3
100:1 when using DOLMAR HP 100 high-performance two-
stroke engine oil, i. e. mix 100 parts gasoline with 1 part
oil.
40:1 when using other two-stroke engine oils, i. e. mix 40
parts gasoline with 1 part oil.
NOTE: For preparing the fuel-oil mixture first mix the entire oil
quantity with half of the fuel required, then add the remaining
fuel. Thoroughly shake the mixture before filling it into the chain
saw tank.
It is not wise to add more engine oil than specified to ensure
safe operation. This will only result in a higher production of
combus-tion residues which will pollute the environment and
clog the exhaust channel in the cylinder as well as the muffler.
In addition, fuel consumption will rise and performance will
decrease.
NOTE: Fuel cannot be stored for an unlimited period of time.
Buy only as much as will be consumed in 4 weeks. Use only
approved and marked containers for transport and stor-
age.
