1.3 INFORMATION ABOUT THE MACHINE
Before leaving the production plant, this specific model undergoes stringent testing to ensure
maximum reliability and safety.
1.3.1 Intended uses
The models presented in this manual are exclusively designed for cutting solid wood into chunks to be
fed into fireplaces, stoves, wood-burning ovens, boilers, thermal cookers, barbecues and more, or to be
subsequently cut with other machines (e.g., woodcutter).
Any use other than that specified is considered improper.
The person operating the machine must always be positioned in front of the tilting table during use.
Operating position
Machines powered by a cardan shaft and by internal combustion engine must remain connected to the
tractor at all times during use.
The machine cannot be used indoors.
These machines are usually used during the day. If use at night or in reduced visibility conditions is
required, a proper lighting system must be employed around the machine.
Never use the machine in closed or poorly ventilated rooms.

For models with log splitter (PLUS / PRO)
When operating the log splitter, you must always be positioned on the right side of the machine, at the
controls for operating the splitting wedge (A), as shown in the figure (“Two-hand control” – During the
cutting operation, the hands are always in a safe position).
ATTENTION!
THE MACHINE MUST BE OPERATED BY ONE OPERATOR ONLY, WHO MUST
BE AUTHORISED, INSTRUCTED AND PROPERLY TRAINED.

1.3.2 Machine description
SHARK saws are the most efficient way of cutting wood.
The machine is essentially composed of a tilting table on which the log to be cut is placed. After
manually operating the release lever, the table is manually pushed by the operator towards the saw
blade, which then cuts into logs.
The cutting blade made of widia, the three-belt drive and the crankcases that segregate all moving
parts make it possible to work safely and very quickly.
The BALFOR s.r.l. company produces this type of circular saw in different versions to meet specific
customer needs.
Cardan models: SHARK 700 C – 750 C
Electric models: SHARK 700 EM – 700 ET – 750 ET
Internal combustion engine models: SHARK 700 SB – 750 SB / SHARK 700 SB-ROAD– 750 SB-ROAD
Conveyor belt models: SHARK EXPERT 700 – 750
Conveyor belt and log splitter models: SHARK EXPERT PLUS / PRO 700 - 750
The numbers “700”, “750” indicate the diameter (in mm) of the cutting disc.
The information in the following chapters applies to all machine models.
In some sections, specific information will be given depending on the machine model and version you
are using.
PLEASE NOTE
FOR ELECTRIC VERSIONS
Failures on electrical parts due to inadequate connections, voltage fluctuations and incorrectly
sized cable extensions will not be covered by warranty.
