Checking the automatic lubrication
Before commencing work, check the automatic chain lubrication and oil gauge. Switch on the
chain saw and hold it above the ground. Be careful not to allow the chain saw to touch the
ground. For safety reasons it is best to keep a clearance of at least 20 cm. If you now see
growing traces of oil, the chain lubrication system is working correctly. If there are no traces of
oil at all, try cleaning the oil outlet (Fig 2, C), the upper chain tensioning borehole (E) and the
oil duct, or contact your Customer Service.
9.7
Chain lubricants
The service life of saw chains and guide bars depends to a large extent on the quality of the
lubricant used. Old oil must not be used! Use only environment-friendly chain lubricant. Store
chain lubricant only in containers which comply with the regulations.
9.8
Guide bar
The guide bar (7) is subjected to especially severe wear and tear at the nose and the bottom.
To avoid one-sided wear and tear, turn the guide bar over every time when you sharpen the
chain.
9.9
Chain wheel
The chain wheel (16) is subjected to especially high wear and tear. If you notice deep wear
marks on the teeth, the chain wheel must be replaced. A worn chain wheel curtails the service
life of the saw chain. Have the chain wheel replaced by a specialist dealer or your Customer
Service.
9.10
Chain guard
The chain guard must be clipped onto the chain and sword as soon as the sawing work has
been completed and whenever the chainsaw has to be transported.
9.11
Chain brake
In the event of kick-back, the chain brake (3) will be actuated via the front finger guard. The
front finger guard is pushed forwards by the back of the hand and this causes the chain brake
to stop the chain saw, or rather the motor, within 0.15 s (Fig. 5, I).
9.12
Releasing the chain brake (Fig. 5)
To be able to use your chain saw again, you must release the saw chain again. First, switch
off the chainsaw. Then push the front finger guard (3) back into the vertical position until it
locks in place (Fig 5, H). The chain brake is now fully functional again.
9.13
Sharpening the saw chain
You can have your saw chain sharpened fast and correctly by specialist dealers, from whom
you can also obtain chain sharpening equipment to enable you to sharpen the chain yourself.
Please follow the corresponding operating instructions.
Take care of your tools. Keep your tools sharp and clean to enable you to work well and
safely. Follow the maintenance regulations and the instructions for changing tools

STARTING UP
Always wear safety goggles, ear muffs, protective gloves and heavy-duty
work clothes!
Use the saw only with approved extension cables with the prescribed insulation and
connections designed for outdoor use (approved rubber-sheathed cables) which fit the
chainsaw plug.
The chain saw is equipped with two safety switches, requiring the use of both hands.
