4.2 Adjusting the chain tension
The chain has the correct tension if it makes full contact with the guide bar but can still be
lifted off the guide bar by hand by around 2 - 4 mm.

13a / 13b: depending on the version
• Loosen the retaining nuts on the rail cover (12) using the enclosed combination tool.
• To increase the chain tension, turn the chain tensioning bolt (13) clockwise,
• To slacken the chain tension, turn the chain tensioning bolt anti-clockwise.
• Place the rail tip on a suitable wooden
support (e.g. a tree stump), and in doing so
press the guide rail slightly upwards.
• In this position, set the correct chain tension
and tighten the retaining nuts.
• Then check the chain tension again and
correct as required.
(schematic diagram)
Note: the process of placing the tip down and pushing up the guide rail simulates the working position
while cutting.
Always check the chain tension before starting the device and adjust it as required.
You should also check the chain tension again and adjust it as required once the power tool
has warmed up and again intermittently while working with the tool – but make sure the engine
is switched off first!
As the chain tightens again slightly when the device cools off, slacken the chain tension a little
once you have finished work before putting the chainsaw into storage.
