3 . With the help of protective gloves, wrap the saw chain around the guide bar, making sure that the
teeth are aimed in the direction of rotation. The chain should be properly set in the slot running along
the entire outside edge of the guide bar.
4 . Place the saw chain around the sprocket while lining up the slot in the guide bar with the internal bolt
at the base of the saw and the chain tensioning pin in the guide bar’s pin hole. The chain tensioning pin
may need adjustment to properly align with the hole in the guide bar. Use the chain tensioning wheel to
adjust its location until it fits in the guide bar.
5 .Turn the chain tensioning wheel to preliminarily tighten the guide bar enough that it stays in place.
While holding the bar still, place the cover back onto the saw. Make sure the tab properly lines up
with the slot on the body of the saw. Lock the cover in place with the cover locking knob by turning it
clockwise until it engages.
Tensioning the chain : illustration 2.5
1 . Check the chain tension by pulling the saw chain away from the guide bar. A properly tensioned chain
should have roughly 3 mm of distance between itself and the bar guide.
2 . If adjustments are needed, loosen the bar adjustment locking knob one full turn.
3 . To adjust the saw chain tension, rotate the chain tensioning wheel. Rotating the wheel upwards
increases the tension while rotating it downwards decreases tension. A properly tensioned chain should
have no sag and should only be able to be pulled 3 mm away from the guide bar of the saw.
4 .Once the chain is properly tensioned, tighten the locking knob. Do not over-tension the chain: this will
lead to excessive wear and reduces the life of both the bar and chain.
Note: The saw chain must be tensioned properly in order to
ensure safe operation.
The chain tension is optimal if the saw chain can be lifted 3 mm from the centre of the guide bar. Since
the saw chain heats up during operation, its length can therefore fluctuate. Check the chain tension
every 10 minutes of operation and adjust as necessary, particularly for new saw chains. Slacken the saw
chain after the work is completed since it shortens when cooling down. In doing so, you can elongate the
chain’s life and prevent damage.
4.3 PREPARATION
Before each use, check the following items to ensure safe working conditions.
Chain saw :
Before beginning work, inspect the chain saw for damage to the housing, the saw chain and the guide
bar. Never use an obviously damaged machine.
Chain oil :
Check the fill level of the oil tank. Also check whether there is sufficient oil available while working. Never
operate the saw if there is no oil or the oil level has dropped below the minimum oil level mark, in order
to prevent damage to the chain saw. On average, an oil filling is sufficient for approximately 10 minutes
of cutting operation (depending the duration of pauses and the density of the work piece).
Saw chain :
Check the tension of the saw and the condition of the saw. The sharper the saw chain is, the easier and
more manageable operations will be. The same applies to chain tension. Check the tension every 10
minutes of operation to maximise safety. New saw chains in particular are subject to changes due to the
heat created by operation.
Safety equipement and protective clothing :
Make absolutely sure to wear the appropriate close-fitting protective clothing such as protective pants,
gloves and safety shoes. Wear a safety helmet with integrated hearing protection and a face guard to
provide protection against falling and recoiling branches.
Do secure long hair so that it is above shoulder level.
Use the following safety clothing and protective equipment when operating the product:
