CUTTING CAPACITY
CARIF 260 BSA is a completely hydraulic band-saw designed of small dimensions, high
robustness and for practical working operations.
THE IMPORTANCE TO CHOOSE A FULLY HYDRAULIC BAND SAW
All CARIF models 260/320/450 are completely Hydraulic:
closure of the vice, bow feed and pressure. The Carif hydraulic patented system has been
designed with 2 commands: BOW FEED and CUTTING PRESSURE.
Thanks to this system the blade regularly descends, with a constant auto-regulation for
every material type, section and thickness.
ADVANTAGES with Hydraulic Bandsaw:
+ Increased productivity: no operator during cutting cycle
+ Always straight cut: auto-regulation based on material hardness and section
+ Longer blade life: no blade stress when worn out
+ Easy to use: fast setting operation
+ Fast operation time: no idle time, more eciency

The machine must be transported
horizontally.
In case you have to store the machine, take
the following cares:
• Place the machine in a close environment;
• Avoid humid places;
• The storing temperature must not fall
under 5° C;
• To avoid that the machine might become
rusty, apply the special prevention liquid
where it’s needed.
Usually, the machine is delivered bolted
on a pallet and covered with a cardboard
packing. On this cardboard you can find
machine model references, weight and
manufacturer’s references.
To transport the packed machine you need
a common fork lift.
Before moving the machine from the pallet
to the installation point you need to:
• verify the weight of the machine
(Kg 320);
• verify the overall dimensions;
• verify the lifting points.
Aboutliftingofthe machine,inthebasement
there are 4 holes, aimed for the application
of shackles (not standard equipment), in
order to make the grip safer.
3.1 Storage and transportation
3. Installation
While laying and maintenance operating, you need to plan the safest
transport of all the parts of the machine. You need to use suitable equipment,
maneuvered by a skilled sta, in order to avoid to damage the sawing
machine and to cause accidents to the sta.
Use shackles only for the purpose they have been made for.

tension presence trhough light “2”
b) Select the cutting angle (90°/45°/60°)
acting on the rotating support through the
service key.
c) Select cutting speed (33-66 m/1’)
through button “3”.
d) Activate the blade rotation by button
“4”.
e) The bow feed can be set through the
handle “A” (BOW FEED) on the Hydraulic
pump.
f) The pressure can be set through the
knurl knob “B” (CUTTING PRESSURE) on
the Hydraulic pump.

4.2 Hydraulic Pump
During the cutting operation of all types
of material, it is very important to maintain
constant the pressure of the blade on
the piece to cut. This guarantees always
straight cut, avoiding any blade deforming
and increase blade-life.
On CARIF models 260/320/450 BSA is
mounted a patented hydraulic gear pump
that allows the fine regulation of the down
stroke speed “BOW FEED” (A) and the
“CUTTING PRESSURE” (B).
Thanks to these 2 hydraulic commands it
is possible to cut optimally every material
section.
• “BOW FEED” (A) permitting sensible
regulation for cutting of all types of
profiles and tubes having tin thickness,
also 1mm (.04”).
• “CUTTING PRESSURE” (B) for cutting of
all types of materials of every resistance
and hardness. This pressure auto-
regulate itself on the base of: blade
stress, material section and blade wear.
(A) BOW FEED=medium
(B) CUTTING PRESSURE= medium/high
In case of cutting full bars, the blade encounters dierent kind of
surfaces during its cutting path.
Thanks to the “CUTTING PRESSURE” (auto-regulation of the hydraulic
oil passage) it can maintain constant the adjusted pressure of the
blade to obtain a longer blade life and better cutting quality.
(A) BOW FEED=low
(B) CUTTING PRESSURE=medium
In case of cutting tubes of profiles, it is advised to adjust a low feeding
(BOW FEED) and a medium pressure (CUTTING PRESSURE), thus to
obtain a constant feeding of the blade in the material also in the point
when it encounters less material (auto-regulation of the hydraulic oil
passage).
(A) BOW FEED=medium
(B) CUTTING PRESSURE=high
In case of dicult cuts, with a wide cutting surface, thanks to the
possibility of having the 2 regulations: feeding (BOW FEED) and
pressure (CUTTING PRESSURE), the machine can perform the cut
without any problem. Mind to choose a blade type with large teeth
per inch (example T=3/4 or T=2/3) and refrigerate well the blade.
In case the frame comes down irregularly, perform some idle strokes to expel
possible air in the frame cylinder.

260 BSA

The table below can advise to choose the right blade tpi (teeth per inch) to use for dierent
material sections:
4.3 Saw Blades
Teeth per Inch
(variable)
Tubes or Profiles
(thickness)
Full Material
To obtain the best performance in terms of durability and cutting precision,
it is suggested to perform the first cuts with low pressure and slightly
increase to reach the optimum value for the material to cut.
6/10 tpi 2 ÷ 4 mm 5 ÷ 30 mm
4/6 tpi 4 ÷ 12 mm 30 ÷ 100 mm
3/4 tpi > 12 mm > 80 mm

260 BSA

For a better holding of the material in
the vice, thus an much better blade life
and cutting quality, it is suggested to fix
the dierent material sections as pictures

5. Malfuctioning, causes and actions
Remove the screw (713), extract the
spring (711) and the small piston
(710), by a M6 screw l = 60 mm
approx. Verify if the spring (711)
is broken, and the small piston
surface (710).
Replace what’s damaged.
The spring (711)
is broken or the
small piston (710) is
seized.
Bow doesn’t lift.
Check the oil level (325) and, if it’s
needed, add oil from the plug (324).
Unscrew the cutting pressure
regulator (702). Remove the spring
(704) and the sphere (705) and
clean the oil hole. Reassemble.
Make the frame lift completely
sometimes, in order to eliminate the
air bubbles in the hydraulic system.
The machine is new and needs
some days of running in. Then, the
problem disappears by itself.

IMPORTANT: Gear pump substitution and oil replacement.
Before to start the machine:
• Remove the screw (716) and verify that the oil leaks out (to avoid gear
pump seizure).
• Close the screw (716) and lock it (to avoid air suction).

Check their setting as it follows:
loosen the grub screw (M6), push
by a tool on the pin (P), in order to
eliminate every clearance between
the blade and the tips. Lock the
grub screw.
Condition of the
hard metal tips.
The cut is not
perpendicular.
Check the wearing condition of the
tips and the bearings. Eventually
replace them.
