away from the body while holding the pull 
starter cord in the left hand.

The chain brake should always be engaged 
before lowering a running saw onto its strop.
Operators should always check the saw has 
sufficient fuel before undertaking critical cuts.

One-hand use of the chainsaw

positioning or in preference to a handsaw when 
cutting small diameter wood at the branch tips.
Tree service chainsaws should only be used one-

handed where:

-  the operator cannot gain a work position 

enabling two-handed use; and

-  they need to support their working position 

with one hand; and

-  the saw is being used at full stretch, at right 

angles to and out of line with the operator’s 
body (Fig. 20).

Operators should never:
-  cut with the kickback zone at the tip of the 

chainsaw guide bar 

-  ‘hold and cut’ sections
-  attempt to catch falling sections.

Freeing a trapped saw
If the saw should become trapped during cutting, 
operators should:
-  switch off the saw and attach it securely to the 

tree inboard (i.e. towards the trunk side) of the 
cut or to a separate tool line;

-  pull the saw from the kerf whilst lifting the 

branch as necessary;

-  if necessary, use a handsaw or second chain 

saw to release the trapped saw by cutting a 
minimum of 30 cm away from the trapped 
saw.

Whether a handsaw or a chainsaw is used to free 
a stuck saw, the release cuts should always be 
outboard (toward the tips of the branch), in order 
to prevent the saw being taken with the section 
and further complicating the situation.

PROHIBITED USE

WARNING - Always follow the safety 
regulations. This chain saw is designed 

and built for pruning and tending standing 
trees or shrubs. It is forbidden to cut other 
types of material. Vibrations and  kickback

requirements of the safety regulations would 
not be respected. Do not use the chainsaw as 
a lever for lifting, moving or splitting objects. 
Do not lock it over fixed stands. It is forbidden 
to hitch tools or applications to the P.t.o. that 
are not specified by the manufacturer.

  WARNING - Do not use the pruning chain 

saw for felling or bucking trees.

OPERATING INSTRUCTIONS
LIMBING
a)  Always start from the larger diameter and 

move towards the tip to cut off limbs and any 
secondary branches.

b)  Always find the safest and most stable 

position before accelerating the chainsaw. If 
necessary, keep your balance by resting your 
knee on the trunk itself.

c)  Keep the chainsaw on the trunk so as not to 

get too tired, turning it onto the left- or right-
hand side depending on the position of the 
branch to cut (Fig. 22).

d)  In the case of branches under tension, find a 

safe position to protect yourself if they whip 
back. Always start the cut from the opposite 
side to the bend.

e)  When lopping large diameter branches make 

use of the bumper spike.

WARNING - Do not use the upper edge 
of the tip of the guide bar to cross-cut; 

otherwise you might risk a kickback.
PRECAUTIONS FOR THE WORK AREA 

 - Do not work near electrical cables.
 - Work only in conditions offering sufficient
