MASONRY 350 F
IMER INTERNATIONAL S.p.A.
- Turn off the engine before topping up the tank with
petrol.
Saws with endothermic engines must be used in the open air. If
they have to be used in closed environments, the openings must
be provided to conduct gases from the engine’s exhaust pipe to
the outside using appropriate non-flammable flexible tubes.
These must be checked for leaks and breakages at the beginning
of every shift.
- Do not start the machine with the blade in the
workpiece.
When the saw is not being used, turn the petrol cock to the OFF
position.
10.1 STARTING ROTATION OF THE CUTTING WHEEL.
Gradually move the lever (ref.17; fig.1) so as to bring the motor
revs up to normal working speed and start the wheel turning at
the cutting speed foreseen.
11. STARTING THE MACHINE
Before cutting:
1 – Check that there is enough cooling water in the tank.
2 - adjust the flow of cooling water by turning the cock next to the
blade guard (do not perform cutting without water).
3 - Ensure that blade rotation corresponds to the indications on
the blade guard.
4 – If everything is in order, work can begin.
12. EMERGENCY - STOP
- In an emergency, stop the machine by pressing the
stop control switch (ref. 7, fig. 1).
13. BLADE INSTALLATION (Fig.5)
By means of a hex wrench no.10, unscrew the 3 screws that
lock the moving blade guard (ref.3). Use a hex wrench no. 13 to
remove the screw that locks the flanges on the disc: this screw
has a left-hand thread (rif.1). Remove the mobile flange (rif.2)
and check that the flanges, disc shaft and blade are not damaged.
- Never use worn blades or blades with missing segments.
- Only use blades that are designed for the number of
revolutions indicated on the machine rating plate.
- Check that blade rotation corresponds to that
indicated on the blade guard.
Centre the blade against the fixed flange, position the mobile
flange and tighten the securing screw by means of a hex
wrench no. 13 (turn clockwise). Refit the moving blade guard,
tightening the 3 screws (ref.3).
- Ensure that the blade guard (ref.3) is locked
securely into position.
- WARNING! An incorrectly installed blade, or a
screw insufficiently tightened can provoke damage to
the machine or injury to persons.
- Note that the blade must have
an external diameter of 14"in. , a
central hole diameter of 1" in. and max.
thickness of 1/8" in..
- Check that the blade to be used
is suitable for the material to be cut.
- Do not use blades for wood!
(fig. 6).
14. USE
- Leave a space of at least 5 ft. around the machine to operate
in full safety.
- Do not allow other persons to approach the
machine during cutting.
- Never use the machine in fire-risk areas. Sparks can cause
fire or explosions.
- Make sure that the machine is switched off before positioning
or handling.
- Always ensure that the blade is free of any contact before start-up.
- Ensure correct installation of all protective devices.
- Before starting work, fill the water tank. Top up during operation
whenever necessary: N.B. the pump suction hose must always remain
immersed in water.
- WARNING! For safety purposes the removal of protective
guards from the machine is strictly prohibited.
- WARNING! Always switch off the machine before
carrying out blade adjustment.
Loading and unloading pieces on the machine cutting table.
To avoid the risk of accidental contact with the cutting wheel, the
pieces must be positioned and removed from the carriage with the
cutting wheel stopped. This is done by adjusting the lever (ref.17;fig.1)
so as to reduce the revs to minimum, thus disengaging the clutch.
14.1 VERTICAL BLADE MOVEMENT
To raise or lower the blade, slacken the support locking handle turning
it anti-clockwise (ref. 11, fig. 1). The blade support remains free to
rotate, so it can be secured in the desired position, fully tightening the
handle (ref. 11, fig. 1).
- Ensure that the locking handle is tightened fully before
starting work.
14.2 BLADE POSITIONING FOR 45° CUTS
To make a cut at 45° the 45° support on the carriage is necessary.
Once the workpiece is correctly positioned, cutting can begin, starting
the endothermic engine.
14.3 CUTTING
For safe use of the machine when cutting, push the carriage forwards
as the cut advances, placing your hands to the two sides of the
carriage. Never push directly on the piece to be cut.
- Check that the blade is aligned with the cutting line.
- Place the workpiece on the worktable (ref. 8, fig. 1), resting firmly
against the stop.
- Start the engine.
- Wait until the water reaches the blade.
- Begin cutting.
- Horizontal cutting movement is carried out by pulling the carriage
towards the blade.
- As cutting thickness increases, the blade is subjected to
greater stress. To avoid overloading the engine, the operator
should continually check blade feed speed. The speed will
also depend on the characteristics of the material being cut
(hardness, toughness etc.).
14.3.1 CUTS WITH BLADE LOWERED FROM ABOVE
Bring the blade support to its highest position and lock. Position the
workpiece on the worktable. Start the machine and begin vertical
cutting until the blade reaches its lowest point. Lock the support locking
handle and proceed with horizontal cutting
14.3.2 BLADE CHANGE
To change the blade refer to section 13.
15. MAINTENANCE
- WARNING.. Servicing must always be carried out by
skilled personnel and only after the endothermic engine has
been turned off.
-Always keep the guards in proper working order and
free from damage.Take particular care to ensure that the
blade guards are kept efficient and clean, replacing them if
they are damaged.
- WARNING.. Recommended product for cleaning
mechanical parts: WD-40.
Do not leave the machine outside: it must always be protected from
the weather.
Below is a list of the cleaning operations that must be carried out at the
end of every shift.
15.1 TANK CLEANING
Empty the tank by removing the drain plug. Remove cutting residue
using a jet of water.
