Tensioning The Chain; Lubricating Cutting Equipment - Jonsered 2033T Operator's Manual

3 Tensioning the chain

!
A slack chain may jump off and cause serious
or even fatal injury.
• The more you use a chain the longer it becomes. It is
therefore important to adjust the chain regularly to take up the
slack.
• Check the chain tension every time you refuel.
NOTE! A new saw chain has a running-in period during which
you should check the tension more frequently.
• Tension the chain as tightly
as possible, but not so tight
that you cannot pull it round
freely by hand.
STOP
1. Use the combination
spanner to loosen the bar
nut that holds the clutch
cover and chain brake.
Then retighten the nut
finger-tight by hand.
2. Raise the tip of the bar
and stretch the chain by
tightening the chain
tensioning screw with the
combination spanner.
Tighten the chain until
there is no slack on the
underside of the bar.
3. Keep the tip of the bar
raised, and use the
combination spanner to
tighten the bar nut. Check
that you can pull the chain
round freely by hand, and
that there is still no slack
under the bar.
The position of the chain tensioning screw varies from
model to model. See the " What is what" section to find out
where it is on your saw.

SAFETY INSTRUCTIONS

4 Lubricating cutting equipment

!
Poor lubrication of cutting equipment may
cause the chain to snap and lead to serious,
even fatal injuries.
!
Prolonged inhalation of exhaust gases from
the engine, chain lubrication oil mist and/or
saw dust can be unhealthy.
A Chain oil
• Chainsaw chain oil must demonstrate good adhesion to the
chain and also maintain its flow caracteristics regardless of
whether it is warm summer or cold winter weather.
• As a chainsaw manufacturer we have developed an optimal
chain oil which, with its vegetable oil base, is also
biodegradable. We recommend the use of our own oil for
both maximum chain life and to minimise environmental
damage.
• If our own chain oil is not available, standard chain oil is
recommended.
• In areas where oil specifically for lubrication of saw chains is
unavailable, ordinary EP 90 transmission oil may be used.
• Never use waste oil!
It is damaging to you, the saw and the environment.
B Filling with chain oil
• The saw is equipped with
automatic chain lubrication.
The oil flow is adjustable.
• The sizes of the chain oil
tank and fuel tank have
been chosen so that the
saw will run out of fuel
before running out of oil.
This means that you should
never run with a dry chain.
However, this safety feature
requires that you use the
right sort of chain oil (if the
oil is too thin it will run out
before the fuel), and that
you adjust the carburettor
as recommended (a weak
mixture may mean that the
fuel lasts longer than the
oil). You should also use the
recommended cutting
equipment (a bar that is too
long will use more chain oil).
The above conditions also
apply to models with an
adjustable oil pump.
