A = Retraction
The retraction occurs when the chain suddenly
gets stuck on the underside of the rail, because
it gets jammed or hits a foreign object in the
wood. The chain then pulls the saw forward. The
retraction often happens when the chain does
not run at full speed when in contact with the
wood.
Avoid retraction
1. Be aware of the forces and situations that can
cause the chain to stick to the underside of the
rail.
2. Always start cutting with the chain running at
full speed.
B = Recoil
The recoil occurs when the chain suddenly gets
stuck on the top of the rail because it gets caught
or hits a foreign object in the wood. The chain
could then press the saw against the operator
with a jerk. Recoiling often happen when the top
of the rail is used for cutting.
Avoid recoil
- Risk of blowback! There is always a risk of
blowback, if the blade tip touches branches
or other objects. The brush cutters will be
uncontrollable and can be pushed with great
force in the direction of the operator.
1. Be aware of the forces and situations that can
cause the chain to jam to the top of the rail.
2. Do not cut more than one branch at a time.
3. Do not tilt the rail aside when pulling it out of
a cutting gap, otherwise the chain could become
trapped.
8. Cleaning, maintenance, transport
and storage
RISK OF INJURY
CAUTION: Always wear protective
gloves when working on and around
cutting tools.
To avoid the risk of unintentional
starting, pull out the spark plug
connector.
8.1 Cleaning
Use a damp cloth to clean the plastic parts. Do
not use detergents, solvents or sharp objects.
Due to technical reasons, wet grass and weeds
wrap around the drive axle under the cutting
protection.
Remove them, otherwise the engine will overheat
due to excessive friction.
8.2 Maintenance
8.2.1 Regular checks
Please note that the following information refers
to normal use. Under certain circumstances
(longer daily work, heavy dust load, etc.), the
specified intervals shorten accordingly.
