Never operate the chain saw with arms fully extended. Do not  
attempt to saw areas which are dif

fi

 cult to reach, or on a ladder. 

Never saw above shoulder height.
Sawing is optimized when the chain speed remains steady 
during cutting. Beware when reaching the end of the cut. The 
weight of the chain saw changes unexpectedly as it cuts free 
from the wood. Danger of injury to the legs and feet.
Always remove the chain saw from a wood cut while the saw 
chain is running.

MAINTENANCE AND SERVICE

Maintenance and Cleaning

●

  Warning! Switch off, remove plug from mains before adjust-

ing cleaning or if the cable is cut, damaged or entangled.

●

  For safe and proper working, always keep the machine and 

ventilation slots clean.

Note: To ensure long and reliable service, carry out the fol-
lowing maintenance regularly. Regulary check the chain saw 
for obvious defects such as loose, dislodged or damaged saw 
chain and chain bar, loose 

fi

 xings and worn or damaged com-

ponents.

RUN-DOWN BRAKE/KICKBACK BRAKE

The chain saw is equipped with two safety features:
The run-down brake stops the saw chain after releasing the 
On/Off switch 3.
The kickback brake is a safety mechanism activated through 
the front hand guard 5 when kickback occurs. Chain stop re-
sponse time is 0.1 seconds.

WORKING WITH THE CHAIN SAW

Before Cutting
Before starting operation and periodically during cutting, carry 
out the following checks:
– Is the chain saw in a fail-safe condition?
– Is the oil reservoir 

fi

 lled? Check oil level gauge prior to start-

ing and regularly during operation. Re

fi

 ll oil when oil level has 

reached the bottom edge of the viewing glass.
The oil tank 

fi

 lling will last approx. 15 minutes, depending on 

sawing intensity and stops.
– Is the saw chain properly tensioned and sharp? Check chain 
tension every 10 minutes during operation. Upon initial opera-
tion, new chains can lengthen considerably. The condition of 
the chain in

fl

 uences the cutting performance.

Only a sharp chain protects from overload.
– Is the kickback brake deactivated and its function ensured?
– Are you wearing the required protective equipment? Wear 
safety glasses and hearing protection. Further protective equip-
ment for head, hands, legs and feet is recommended.
Suitable protective clothing reduces the danger of injury from 
thrown about cutting material and accidental touching of the 
saw chain.

KICKBACK

Kickback is the sudden backward/upward motion of the chain 
saw, occuring when the chain (at the tip of the chain bar) comes 
in contact with a log or wood, or when the chain becomes 
jammed.
When kickback occurs, the chainsaw reacts unpredictable and 
can cause heavy injuries to the operator or bystanders. Par-
ticular attention must be given when sawing sidewards, slanted 
or during length cuts, as the gripping teeth 12 usually can not 
be applied.
To avoid kickback:
– Saw with the chain bar at a 

fl

 at angle.

– Never work with a loose, widely stretched or heavily worn 
out saw chain.
– Sharpen the saw chain as speci

fi

 ed.

– Never saw above shoulder height.
– Never work with the tip of the chain.
– Always hold a chain saw 

fi

 rmly with both hands.

– Apply the metal gripping teeth 12 for leverage.
– Ensure correct chain tension.

GENERAL BEHAVIOUR

Always hold the chain saw 

fi

 rmly with both hands. Front handle 

with the left hand and rear handle with the right hand. Fully 
grip both handles with thumb and 

fi

 ngers at all times during op-

eration. Never operate chain saw using only one hand. Ensure 
power cord is located to the rear, and keep it out of the range 
of the saw chain and cutting material; position yourself in such 
a manner that the mains cable can not get caught in branches 
and twigs. Use the chain saw only with secure footing. Hold the 
chain saw at the right-hand side of your body.
The chain must be running at full speed before it makes contact 
with the wood. Use the gripping teeth 12 to support the chain 
saw on the wood. Use the gripping teeth as a leverage point 
while cutting.
Reset the gripping teeth at a lower point when sawing thicker 
logs or tree trunks. For this, pull the chain saw slightly back-
wards until the gripping teeth release, and reposition at lower 
level to continue sawing. Do not remove the chain saw com-
pletely out of the cut.
Do not force the saw chain while cutting, let the chain do the 
work, using the gripping teeth 12 to apply minimal leverage 
pressure.
