Then assemble the guide bar with the saw chain as follows:
− Place the guide bar with the saw chain on the chain wheel (16) and guide bolt (17).
− Place the saw chain round the chain wheel (16) and make sure it is correctly mounted (see
Fig. 2).
− Place the cover (6) on top and tighten gently with the lock nut (5). Now the saw chain has
to be correctly tensioned.
9.2
Tensioning the saw chain
Always pull the plug out of the power socket before doing any work on the
chainsaw!
Wear safety gloves!
Make sure the saw chain (4) is inside the guide groove of the guide bar (7) (Fig. 2)!
Turn the outer Knob clockwise until the saw chain is correctly tensioned, then rotate the inside
knob (5) to block the guide bar in that position.
While the inside knob is being tightened, the guide bar must then be pushed upwards.
Check the chain tension again (see Fig. 3). Do not tension the chain too tightly.
When cold, it should be possible to lift the chain in the middle of the guide bar approx. 5 mm.
Tighten the lock nut (5) securely.
When warm, the saw chain will expand and slacken and there is a danger of it jumping off the
rail altogether. Re-tension if necessary.
If the saw chain is re-tensioned when hot, it must be loosened again when the sawing work
has been completed. Otherwise, the contraction which takes place as the chain cools would
result in excessively high tension.
A new saw chain requires a running-in period of approx. 5 minutes. Chain lubrication is very
important at this stage. After running in, check chain tension and re-tension if necessary.
9.3
Filling in chain oil (Fig. 4)
To prevent dirt getting inside the tank, clean the oil tank cap (14) before opening. Check the
contents of the oil tank during sawing work by checking the oil gauge (15). Close the oil tank
cap tightly and wipe away any spills.
9.4
Securing the extension lead (Fig. 6)
Only use extension leads suitable for outdoor use. The cross section of the cable (max. length
of extension cord: 75 m) must be at least 1.5 mm². Secure the chainsaw flex to the extension
lead by inserting the extension lead into the strain relief gap of the housing.
Extension leads longer than 30 m will reduce the performance of the chainsaw.
9.5
Chain lubrication
To prevent excessive wear, the saw chain and guide bar must be evenly lubricated during
operation.
Lubrication is automatic. Never work without chain lubrication. If the chain runs dry, the entire
cutting apparatus will quickly become severely damaged. It is therefore important to check
both chain lubrication and the oil gauge every use (Fig. 4).
Never use the saw when the oil level is below the "Min." mark.
− Min.: When only approx. 5 mm of oil is visible at the lower rim of the oil gauge (15), you
must top up with oil.
− Max.: Top up with oil until the window is full.
