Filling Chain Oil Tank; Checking Chain Lubrication - Stihl MS 191 T Instruction Manual

English / USA
If special chain lubricant is not available,
you may – in an emergency – use an HD
single grade or multigrade engine oil
with a viscosity that suits the prevailing
outside temperature.
Do not use waste oil!
Medical studies have shown that
renewed contact with waste oil can
cause skin cancer. Moreover, waste
is environmentally harmful!
Waste oil does not have the
necessary lubricating properties
and is unsuitable for chain
lubrication.

Filling Chain
Oil Tank
:
Thoroughly clean the the oil filler
cap and the area around it to ensure
that no dirt falls into the tank.
:
Refill the chain oil tank every time
you refuel.
There must still be a small amount of oil
in the oil tank when the fuel tank is
empty.
If the oil tank is still partly full, the reason
may be a problem in the oil supply
system: Check chain lubrication, clean
the oilways, contact your STlHL dealer
for assistance if necessary.

Checking Chain Lubrication

The saw chain must always throw off a
small amount of oil.
Never operate your saw without
chain lubrication! If the chain runs
dry, the whole cutting attachment
will be irretrievably damaged within
a very short time. Always check
chain lubrication and oil level in tank
before starting work.
Every new chain has to be broken in for
about 2 to 3 minutes.
After breaking in chain, check chain
tension and adjust if necessary – see
"Checking Chain Tension".
