3. Installation
3.1. Space Requirements
You can install the machine on any suitable and even floor (concrete) in a factory hall. Observe the allowed floor load. The machine
should be aligned using the underlay sheets under the base anchors (not included in the shipment).
While preparing the cutting, the operating staff is allowed to move around the machine only when the machine is not running. When
the machine is running, the operator has to stay only at the control panel so that he/she is able to switch off the machine any time. The
operator must also ensure that no other persons are present in or near the working area of the machine. No unauthorised personnel
may enter the dangerous zone. To prevent injury, the danger zone must also be level and free from any foreign objects and obstacles.
Recommendations/requirements:
• Allow for sufficient space for the feeding and removal of the workpiece and the machine maintenance - the operator's working area
should be delineated at 1 m minimum around the machine and 0.5 m around the roller conveyors.
• In order to ensure safe handling of workpieces and protection of the space behind the cut from falling cut-off pieces, one or more
roller conveyors must be installed, possibly a container for falling cut workpieces.
• Install a lift mechanism for heavy workpieces.
• Ensure proper lighting at the workplace.

3.2. Removal of Temporary Transport Beams and Fixation of the Machine
Use a pallet truck to lift the machine and place it directly on the desired location in the workplace. Unscrew the bolts that hold the
machine in place and remove the transport beams. Lift the machine, remove the beams and lower the machine onto the floor. Level
the machine by laying metal sheets under its legs, possibly anchor to the floor. Remove the anticorrosion film and dust from sliding
surfaces and apply oil. Ensure connection to the mains (see section 3.4.). Pour the coolant (maximum 15 litres) into the tank; the fluid
will gradually flow into the container in the base. The hydraulic unit is fitted with two filling holes that are covered by red transport caps
during the transport (see section 7.5.2.). The cap that is more accessible to the operator has to be removed and replaced by a filling
cap, otherwise a risk of making the entire system inoperable arises, along with the risk of pump damage.
When handling coolants, risks linked to hazardous substances cannot be avoided. Observe the national
norms and recommendations and manufacturer’s or your company’s operating instructions related to
safe handling of coolants.
3.3. Machine installation
Protect the machine against humidity, rain and dust!
The machine may be operated in the ambient temperature between + 5° and + 40°C. The average air temperature must not exceed +
35°C within 24 hours.
+ 35°C. In temperatures below + 5°C the conventional coolants should be replaced by coolants designed for respective
temperatures. In addition to that, replace the oil in the hydraulic unit for a less viscous one.
3.4. Connection to the mains
Such operations must be carried out only by persons with electrician qualifications!
Make sure that the grid voltage, the voltage protection and the connection voltage comply with the power requirements specified in
the point 2. Technical parameters. Only current protection of S characteristics can be installed (for a frequency converter). When
connecting the machine to the mains (3 NPe 50 Hz, 400 V, TN-S), mind the colour coding of wires carefully: L1 brown, L2 black,
L3 grey, N blue, PE yellow-brown. Improper connection of the neutral or PE wires may lead to damage of the electrical
equipment or to and electric shock! Connect the power cable to a protected 16 A socket, in case of direct connection to the mains it
is necessary to fit the supply with a lockable MAIN SWITCH. If the motor rotates in an incorrect direction, swap the conductors L1
brown and L2 black on the junction box.
Failure to observe the aforementioned may lead to incorrect rotation of the bandsaw and the coolant
pump. Danger: Damage to the machine!

4. Machine description
Horizontal metal-cutting band saws allow for cutting of a wide range of different materials. Pressing a single switch will execute the
complete cutting cycle – workpiece clamping, saw blade start, cutting, saw blade stop, arm uplift to the upper (adjustable) position
and vice unclamping. In connection with the hydraulic feed of the saw blade into the cut, these measures significantly increase
cutting productivity, particularly as regards solid materials. All functions can be controlled separately. The feed of the workpiece is
manual. The vice pressure control is included in the basic version of the machine. As the cutting tool, a welded saw blade is used,
which is tensioned mechanically via a blade wheel. The saw blade is driven by the blade wheel, which is driven by a single-speed
motor via a worm-gear unit. In the machining zone, the saw blade guided through the saw blade guide heads. Outside the machining
zone the saw blade is protected by moving and fixed guards. The standard equipment of these machines includes a frequency
converter, which enables a continuous saw blade speed control within the range of 15-90 m/min. The optimum setting of the saw
blade speed substantially increases the productivity of the machine, cutting accuracy and the saw blade service life.

4.2. Control Valve - Saw Blade Feed to the Cut
The control valve allows for a continuous setting of the velocity of saw blade feed towards the cut or stabilizing the saw arm in any
position by mechanical closing. The optimum value of descent can be determined very easily by ear. The saw blade movement must
be noiseless, free from vibrations. Such a state can be achieved by reducing or increasing the pressure force (by the velocity of saw
arm descent). The prerequisite of setting the optimum pressure is selecting the correct saw blade velocity and the optimum size of
the saw blade teeth.

not use the hydraulic cylinder to align long workpieces in the vice! Such operation has to be carried out only manually or by other
means. You can set the clamping force depending on the type of material to be cut on the hydraulic unit using the VICE PRESSURE
CONTROLLER (see section 4.8.1.).
Workpiece clamping procedure:
Raise the arm above the presumed cross-section of the workpiece to be cut. Insert the material between the clamping jaws and align
it parallel to the fixed clamping jaw and set the desired cut length. Slide the clamping jaw of the movable vice to approximately 10 mm
off of the material. The clamping stroke of the hydraulic cylinder is 15 mm. Depending on the mode of the saw - AUTOMAT, or
MANUAL, clamp the material. Check whether the workpiece is properly clamped, otherwise you risk its ejection during
cutting.

4.3.2.Cutting Angle Settings
ARG band saws allow for both perpendicular cuts and cuts up to 60 °. The band saws ARG 260, 300 S.A.F. allow for single-sided
continuous cutting angle settings within 60° on the right. Band saws ARG 260, 300 PLUS S.A.F. allow for double-sided continuous
cutting angle settings within 60° to the right and 45° to the left. The stop bolts facilitate a stable limit angle setting. Before you swing
the arm, unlock the arm with the locking lever and after setting the desired angle, lock the arm again. The desired arm swing angle will
subtract from the angle scale. By the band saws of the PLUS line, before you swing the arm, mind the correct vice positioning in
relation to the desired swing angle in order to prevent a collision of the arm/blade with the vice. If there is a danger of collision, loosen
the adjusting screws of the vice and move the vice in the T groove to the other side while the arm is raised, and lock the vice again.
When swinging the arm of the ARG 260, 300 S.A.F., raise the arm to about 30 mm above the loading surface of the vice in order to
prevent the collision of the saw blade with the vice loading surface. If using the band saw only for perpendicular cuts for a longer time,
we recommend that you carry out a precautionary step and swing the band saw into the angle and back at least once a week,
because the coolant acts aggressively, which can result in jamming of the arm in one position.
WARNING! When using the vertical vice while cutting the workpieces in HVP bundles, you can cut only at 90°.

4.5.Removal of Protective Housing
Caution! You can remove the protective covers only if the MAIN SWITCH is turned off
and secured against restart or if the machine is disconnected from the mains.
Caution: Danger of injury by the sharp teeth of the saw blade. Use protective gloves.
Do not reach between the wheels and the saw blade.
The MAIN SWITCH is turned on, the TOTAL STOP button is unblocked, the SAFETY button is not active. The cutting mode is set to
MANUAL. If the arm is lower than approximately 20 mm above the fixed vice jaw, set the height of the arm uplift to its maximum (see
section 4.9.) and switch the ARM UPLIFT SWITCH to position 0. Press the HYDRAULIC UNIT - START button. Switch the ARM
UPLIFT SWITCH to position 1 and thus raise the arm to its upper position (see section 4.1.). Shut off the control valve of the damper
cylinder (see section 4.2.). Start the arm descent by pressing the button START DESCENT. Lower the saw arm approx. 30 mm
above the fixed vice jaw and using the CONTROL VALVE, secure it against descending. Switch off the POWER SWITCH and secure
it against restart.
Unscrew the blade cover (D) an place it aside. Unscrew and slide out the cover of the front rod (A), place it aside and unlock the
angled latch. Open the back cover (C) upwards and secure with latches (B). Use a reverse procedure to mount back the protective
covers. Switch on the POWER SWITCH, or connect the machine to the mains. Then press the SAFETY and HYDRAULIC UNIT
START button. The arm is now in an interposition between the limit switches, therefore is it necessary to switch the arm uplift switch
into position 1 in order to unblock the interposition and allow the arm to ascend.
4.4.Arm - Saw Blade Guidance
The saw arm is made of sturdy cast of grey cast iron, which guarantees outstanding stiffness during band tensioning. The saw blade
is guided by two guide heads both behind and in front of the cut. The heads are fitted with eccentrically placed bearings and hardened
steel blade guides that allow easier rewinding of the saw blade as opposed to wheel guidance. The fixed guide block is placed on a
fixed guide bar and the movable guide block is placed on the movable bar. The moving guide block moves towards the cut material by
30-50 mm manually.
Danger of injury - no cover in the machining area!
Caution! You can remove the protective covers only if the MAIN SWITCH is turned off and
secured against restart or if the machine is disconnected from the mains.
Caution: Danger of injury by the sharp teeth of the saw blade. Use protective gloves. Do not
reach between the wheels and the saw blade.
4.6.Replacement, Tensioning and Adjustment of the Saw Blade
A timely replacement of the saw blade is needed to achieve good cutting performance, surface finish quality and compliance with
workpiece dimensions. Blunt saw blades cause high consumption of electrical power, scarf cuts and rough cutting surfaces.One of
the decisive factors affecting the quality of the cut and the life of the cutting tool is the correct and sufficient saw blade tension.
Follow the instructions in section 4.5. in order to remove the protective covers. The machine is switched off and secured against
restart, the arm is locked approximately 30 mm above the fixed vice jaw.

Use the tensioning star nut to release the wheel and the blade. Take the saw blade off of the moving wheels and push it off the guide
heads. Insert the new saw blade in the guide heads. Place it on the blade wheels (you can control the position of the tensioning wheel
by the tensioning star nut). Tighten the saw blade. Tension the star nut, so that the disc springs are fully compressed (no light
coming through)! In this way, you can achieve correct tensioning of the saw blade. Install and close the protective covers of the
saw blade. Turn on the MAIN SWITCH, press the SAFETY button and turn on the hydraulic unit. Switch to the MANUAL MODE and
set the minimum saw blade speed by a SAW BLADE SPEED CONTROLLER. Press the START button of the saw blade to start the
saw blade so that it turns approximately once of the full length. Switch off the MAIN SWITCH and secure it against restart. As
described in section 4.5, remove the protective covers of the saw blade and check if the saw blade is correctly fitted on the guide
heads and correctly installed on the blade wheels (see figure). The machine is also fitted with a control hole that allows you to check
the condition of the saw blade on the wheels. The hole is covered by a cap.
If the saw blade is not properly set on the wheels, loosen the saw blade a little bit and use the wheel tilting screw to adjust the wheel tilt.
Tension the star nut, so that the disc springs are fully compressed (no light coming through)! Put back the protective covers of
the saw blade, turn on the MAIN SWITCH, press the SAFETY BUTTON and the hydraulic unit. Carry out a saw blade trial run. Switch
off the MAIN SWITCH and secure it against restart, remove the protective covers of the saw blade and once again check the
placement of the saw blade on the wheels. Repeat the procedure, if required. Put back the protective covers of the saw blade, turn on
the MAIN SWITCH, press the SAFETY BUTTON and the hydraulic unit. Carry out the cutting.
4.7. Guide Heads Adjustment
The correct setting of the bearings and the hardened steel blade guides in the guide heads substantially influences the saw
blade life and the quality of the cut. The eccentrically arranged guide head bearings must be set in such a manner that the saw
blade surface is parallel to the surface of hardened steel blade guides with a minimum play (clearance) between the plates and the
blade.
Guide Head Setting Procedure
Follow the instructions in section 4.5. in order to remove the protective covers. The machine is switched off and secured against
restart, the arm is locked approximately 30 mm above the fixed vice jaw. Set the movable guide head, so that the distance between
the guide heads is approximately 20 cm. Disconnect the inlet hoses from the coolant valve. Loosen the tensioning star, take the saw
blade off the wheels and push it off the guide heads. Unscrew the guide heads gradually from the fixed and movable bars, turn them
by 180 ° (with bearings and hardened steel blade guides facing upwards) and screw back to the bars. Make sure that the guide heads
are perpendicular to the guide bars and that the height of the guide heads is identical. If you find special washers between the guide
head and the bar, make sure you place them back afterwards. Check the tightening of the fixed hardened steel blade guides. Insert
approximately 30 cm of an old saw blade in the guide heads between the hardened steel blade guides and the bearings. Set the
hardened steel blade guides using the width adjusting screw, so that the saw blade does moves between the guides without any play
and jamming. When the saw blade has been adjusted, set the eccentrically mounted bearings in such a manner that the bearings do

not “cut” the saw blade, but at the same time you have to prevent too much space for the saw blade between the bearings. When the
saw blade moves, the bearings are carried along by the saw blade. Check the tightness of all bolted joints. Unscrew the guide heads
from the bars. Fit the saw blade on the wheels, check its correct alignment on the wheels and tension the saw blade. Install both
guide heads on the saw blade in the space between the bars and adjust them in the correct position on the bars.You can achieve the
correct guide head height in relation to the saw blade by lifting the guide heads, so that the upper hardened steel guide in the guide
head is about 0.5-1 mm away from the upper edge of the saw blade. See the picture. In this way, the correct guide head height
towards the guide bars is achieved.
Set the guide heads perpendicular to the bars and tighten them. If you fail to achieve perpendicularity, the saw blade will either keep
sliding off or running into the wheels. Put back the protective covers of the saw blade, turn on the MAIN SWITCH, press the SAFETY
BUTTON and the hydraulic unit. Carry out a saw blade trial run. Switch off the MAIN SWITCH and secure it against restart, remove
the protective covers of the saw blade and once again check the placement of the saw blade on the wheels. Make a correction, if
necessary - see section 4.6. Put back the protective covers of the saw blade, turn on the MAIN SWITCH, press the SAFETY
BUTTON and the hydraulic unit. Carry out the cutting. You can watch the video with instructions on www.pilous.cz.

4.8.1. Vice Clamping Force Setting
The hydraulic unit is fitted with a PRESSURE REDUCTION VALVE. It enables setting the required vice clamping force between 13
and 35 bar depending on the kind of the workpiece. Turning the PRESSURE REDUCTION VALVE to the left reduces the pressure,
while turning it to the right increases the pressure (see picture). The specified pressure is shown on the pressure gauge.
If the pressure is set below the clamping force smaller than 13 bar, the safety PRESSURE CONTROLLER OF THE VICE does not
switch on and the saw blade does not start.
4.8. Hydraulic Unit
The hydraulic unit is installed in the machine base. It lifts the band saw arm, feeds the saw blade to the cut, and clamps and unclamps
the vice. When the MAIN SWITCH is on, the HYDRAULIC UNIT - START button serves for activating the electrical system of the
machine and at the same time for starting the hydraulic unit.
