Saw Rebound
Saw rebound can happen when guide bar (7)
touches sawn material or when the chain is blocked
causing the uplift and impact of the saw to rise
suddenly in the opposite direction.
When the rebound
affect occurs, the
machine reacts in
this unexpected
manner, often
causing serious
injury to the person
using the saw or
other people
nearby. When
conducting side, oblique and lateral cuts, special
care should be taken to ensure that the notched rest
(8) are not caught in these situations.
To Avoid Saw Rebound:
Apply the machine as evenly as possible to the •
surface.
Never work with a loose or worn chain. •
Sharpen the chain according to the instructions. •
Never saw above shoulder height. •
Never saw with the upper edge or the end of •
guide bar (7).
Always firmly hold the machine with two hands. •
Use notched rest (8) as a lever. •
Pay attention to correct chain tension. •
Preparation
It is necessary to carry out the following checks
before use and regularly during sawing:
The machine must be in working order •
The oil reservoir must be full. The oil level should •
be checked by looking through window (13) before
and regularly during the work. If the level of oil
reaches the lower edge of the viewing window, the
oil needs to be topped up. One check suffices for
approximately 15 minutes of work (depending on
the intervals and intensity of the work).
The chain must be correctly tensioned and sharp. •
Chain tension should be checked every 10 minutes
during use. Special attention should be paid to new
chains, which often require tightening.
The chain brake initiator must be intact. •
You must use the correct protective clothing. •
General Recommendations
The machine should always be held firmly with •
both hands, the left
hand should hold
the front handle and
the right hand, the
back handle. The
fingers should
constantly encircle
the grip. Under no
circumstances should the operator work with only
one hand. The mains cable should always be behind
the operator, out of the way of the saw chain and
the material to be cut.
The machine •
should only be used
under reliable
support conditions.
The machine should
be held to the right
of the body, slightly
distanced therefrom.
The chain needs to be moving at full speed •
before coming into contact with the wood. When
this has been achieved, the machine should be fixed
to the wood using notched rest (8). During cutting
this support should be used as a lever.
When cutting thick trunks or branches the •
notched rest should be repositioned. To do this,
the machine should be inclined backwards in order
to release the notched rest and allow it to move
downwards. The machine should not be removed
from the cut to do this.
Do not apply intense pressure to the chain •
during cut- ting. Allow the chain to work freely, only
lightly applying pressure, using notched rest (8) as
a lever.
Never use machine with outstretched arms. Do •
not attempt to cut in difficult areas or standing on
a tree. Under no circumstances should work be
carried out above shoulder level.
Optimum cutting results are achieved when the •
speed of rotation of the chain is not reduced after
overload.
Be careful at the final stage of cutting. When the •
machine has just completed the cut, an unexpected
gravity increase effect is produced causing the
danger of injury to feet and legs.
The machine should be taken out of the cut only •
if the chain is moving.
