Air Filter; Spark Plug; Filing The Grass Blade - Jonsered GR 2126D Operator's Manual

Air filter

The air filter should be
cleaned regularly removing
dust and dirt to avoid:
• carburettor malfunction
• starting problems
• reduced engine power
• unnecessary wear to
engine parts
• abnormal fuel
consumption
Clean the filter after every
25 hours or more regularly
if operating conditions are
exceptionally dusty.
Cleaning the air filter
Dismantle the air filter cover and remove the air filter. Wash in
clean, warm soapy water. Ensure that the filter is dry before
refitting. An air filter used for a long period of time can never
be cleaned completely. Therefore it is necessary to replace the
filter from time to time with a new filter. A damaged air filter
must always be replaced.
If the machine is used in dusty conditions the air filter
should be soaked in oil, see the section on "Oiling the air
filter".
Oiling the air filter
Always use filter oil. The
filter oil contains a solvent
to make it spread evenly
through the filter. You
should therefore avoid skin
contact. Put the filter in a
plastic bag and the pour the
filter oil over it. Knead the
plastic bag to distribute the
oil. Squeeze the excess oil
out of the filter inside the
plastic bag and pour off the
excess before fitting the filter
on the machine. Never use
common engine oil. This
would drain through the
filter quite quickly and
collect in the bottom.
MAINTENANCE

Spark plug

The condition of the spark
plug is affected by:
• An incorrect carburettor
setting.
• An incorrect fuel mixture
(too much or faulty oil).
• A dirty air filter.
These factors cause deposits
on the spark plug electrode
that may result in
malfunction or starting
difficulties.
If the machine is low on power, difficult to start or runs
poorly while idling always check the spark plug first.
If the spark plug is dirty, clean it and at the same time check
that the electrode gap is 0.5 mm. The spark plug should be
changed after about one month of operation or earlier if
necessary.
NOTE! Always use the recommended type of spark plug. An
incorrect spark plug can damage the cylinder/piston.

Filing the grass blade

!
• See the cutting
equipment's packaging
for correct filing
instructions.
• The blades are sharpened
using a single cut flat file.
• Sharpen all edges equally
to maintain the balance
of the blade.
!
WARNING!
Always stop the engine before starting
work on any part of the cutting equipment.
This continues to rotate even after the
throttle has been released. Ensure that the
cutting equipment has stopped completely
and remove the cable from the spark plug
before you start to work on it.
WARNING!
Always discard a blade that is bent,
twisted, cracked, shattered or damaged in
any other way. Never attempt to straighten
a twisted blade for use again. Only use
original blades of the prescribed type.
