MAINTENANCE
Cooling system
To maintain as low an operating temperature as possible the
power cutter is equipped with a cooling system.
The cooling system consists of:
1. An air intake on the
starter unit.
2. Air flow guide.
3. Cooling fins on the
flywheel.
4. Cooling fins on the
cylinder
5. Cylinder cover (leads cold
air onto the cylinder).
Clean the cooling system
using a brush at least once
a week, in difficult
conditions more often.
A
dirty or blocked cooling
system leads to the engine
overheating resulting in
damage to the cylinder and
piston.
Muffler
The muffler is designed in
order to reduce the noise level
and to direct the exhaust
gases away from the opera-
tor. The exhaust gases are
hot and can contain sparks,
which may cause fire if
directed against dry and
combustible material.
Never use a saw with a
clogged or defective muffler.
Spark plug
The condition of the spark plug
is affected by:
• An incorrect carburetor
setting.
• An incorrect fuel mixture
(too much 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
(.020"). 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. (see
chapter
”Technical data” )! An incorrect spark plug can damage
the cylinder/piston.

Blade Retipping
!
WARNING! Do not retip ring blades. Because of its design, a ring blade is exposed to different stresses than
a center driven 14 inch diamond blade. First, the drive disc works on the inner diameter of the blade so that
both the drive disc and the blade surface wear. The blade core becomes thinner and the guide becomes
wider which prevents the blade from being driven by the disc. Secondly, the blade is exposed to stress from
the rollers and from the cutting itself, if the blade is not kept perfectly straight. Stress builds up in the blade,
until it may crack or even break if it is totally retipped. A broken blade may cause serious personal injury to
the operator or others. For this reason, Partner will not authorize a ring blade to be totally retipped. A single
segment may sometimes be retipped. Please contact your Partner dealer for instructions.
