• Tighten the fixing screw of the chain wheel cover (Fig. 7).

Caution: All of the chain links must lie properly in the guide groove of the cutter rail.
Notes on tensioning the chain:
The saw chain must be properly tensioned to ensure safe operation. You can tell that the
chain tension is perfect if the saw chain can be lifted by around 3-4 mm in the middle of the
cutter rail. As the saw chain heats up during cutting and thus changes in length, please check
the chain tension every 10 minutes and adjust it again as required. This applies in particular
to new saw chains. When you have finished working slacken the chain again, as the chain will
shorten when it cools down. This will prevent the chain from being damaged.
7.3 Saw chain lubrication
Caution: Always disconnect the mains plug before performing any checks or adjustments.
Always wear protective gloves when working on the chainsaw to protect yourself against
injury.
Caution: Never operate the chain if it is not lubricated with saw chain oil. Use of the chainsaw
without saw chain oil or if the oil level is below the "min" mark (Fig. 10) will damage the
chainsaw.

Caution: Be aware of the temperature conditions:
different lubricants with completely different viscosities are required at different ambient
temperatures. At lower temperatures you will need low viscosity oils in order to achieve a
sufficient lubricating film. However, if the same low viscosity oil is used during the summer it
will become even thinner due to the ambient temperatures alone, and as a result the
lubricating film could break down, causing the chain to overheat and become damaged. In
addition, the chain oil would burn and produce unnecessary pollutants.
Filling the oil tank:
• Place the chainsaw on a flat surface.
• Clean the area around the oil tank cover (Fig. 10) and then clean the oil tank cover.
• Fill the tank with saw chain oil. In the process, make sure that no dirt enters the tank, as this
could cause the oil nozzle to become blocked.
