Pattfield Ergo Tools PE-EKS 1835 Notice Originale page 295

Danger! 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 re-
quired. This applies in particular to new saw chains. When you have
fi nished working slacken the chain again, as the chain will shorten
when it cools down. This will prevent the chain from being damaged.
5.3 Saw chain lubrication
Warning! 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.
Notice! 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/ Item B) will damage the chainsaw.
Notice! Be aware of the temperature conditions: diff erent lubricants
with completely diff erent viscosities are required at diff erent ambi-
ent temperatures. At lower temperatures you will need low viscosity
oils in order to achieve a suffi cient lubricating fi lm. 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 fi lm could break down, causing the chain to overheat and
become damaged. In addition, the chain oil would burn and produce
unnecessary pollutants.
