TECHNICAL CHARACTERISTICS
The robust and highly reliable structure makes these mitres suitable for cutting wood, aluminium and steel in industrial environments, while preserving their usual ease of handling and without restricting their movement.
The FTR250 and FTR250T are fitted with a wide upper table that allows the mitre saw to be transformed into a table saw to carry out cutting (up to a thickness of 40 millimetres).
The FTR250 and FTR250T are fitted with two working tables (upper and lower), and have been provided with a switch to keep the circuit on while pressing, and a lock-on button for free-hands operation when working on the upper bench.
The FTR250 and FTR250T are fitted with a new electronic device to prevent the machine from starting unexpectedly after a break in the voltage supply. When this happens, to restart you must operate the switch to switch-off and then to switch-on. They have a brake circuit to guarantee stopping in approx. three seconds. A single operator is needed to use the mitre saw, of which the design and construction comply with standards EN 61029-1 and EN 60204-1.
SAFETY DEVICES
• At rest, the blade is totally covered by two protectors, one fixed and one mobile, which are automatically opened by the descent of the blade unit when cutting.
• On the upper bench, the blade is covered by one protection which is raised by the work when it comes close to the cut.
WARNING – these protectors must not be removed, in order to prevent danger for the operator.
• In the event that the switch lock button has not been engaged, the machine will stop automatically when the handgrip is released.
WARNING – engaging the lock button disables the safety device provided by the manufacturer and enables push-button start. It is recommended that this device be used with the utmost caution.
The tool has been designed and built so that it is possible to work in all situations with total safety, however, in
special working conditions, gloves and protective goggles should be worn.
The tool has been designed and built to reduce noise to a minimum (see technical data), however, in special conditions the maximum noise level in the workplace might exceed 85 dB(A). In this case, the operator should protect himself from excessive noise by using ear protectors.
GENERAL SAFETY REGULATIONS
See manual “Safety instructions” which is supplied together with this instructions manual.
INSTALLATION
1. ELECTRICAL CONNECTION
Before connecting the machine to the mains, one must make sure that it complies with current regulations in the country where it is used and that the voltage and frequency are as indicated on the characteristics plate.
When extensions are used, make sure that the cross section of the cables is suited to their length. If using roll up extensions, make sure that they unroll completely in order to prevent overheating.
WARNING – before plugging in the machine, make sure that the switch lock button is released.
2. WORKPLACE
The tool that you have purchased is a transportable or semi-stationary electric tool. Only one operator is needed to use it, given its structure, weight and ease of handling.
In normal use, the operator is in front of the machine with the handle to his right. The right hand on the handle allows the machine to be handled completely, in fact, the switch and a safety hook may be accessed without releasing the handle.
CONSTANT ELECTRONICS
The built-in module permits:
- Soft start.
- The maintenance of a practically constant rated speed up to rated power.
- An overload protection system by means of current cut-off in the case of motor overload, in which case the burring machine shuts down and re-starts when the grinding pressure has been reduced.
MITRE SAW ADJUSTMENT - SQUARING
The mitre is delivered by the manufacturer already adjusted and squared according to standard parameters.
WARNING – before making any adjustment of the mitre, unplug the machine.
1. BLADE UNIT LIFTING
An internal spring keeps the motor unit at rest position
(raised).
In this position, a safety hook prevents the unit from
being activated accidentally.
1.1 To unlock the motor unit and to be able to use the machine as a mitre saw, activate the front button D (Fig.1) (the operation may be carried out with the right hand on the handle).
1.2. To use the machine as a bench circular saw, unlock the motor unit as indicated in 1.1, and after lowering it completely, block it with pin P (Fig.1a).
2. BLADE PENETRATION ADJUSTMENT
The depth of penetration has already been adjusted by the manufacturer during testing.
As incorrect adjustment may cause sharpness to be lost quickly and/or the teeth of the blade to be broken, further adjustment might be needed, in which case it will be necessary to work as follows:
- Activate bolt A (Fig.2) and the corresponding lock nut to create a lower limit for the motor housing ideal for preventing the blades from coming into contact with the turntable.
WARNING – once for this operation is complete, make sure that the blade is NOT in contact with the turntable and that the lock nut is tightened.
3. TURNTABLE ADJUSTMENT 0º Regulation (Fig.3)
- Lower the head of the machine and lock with pin P (Fig.1a).
- Set the turntable to zero.
- Loosen the handles V, remove the guides X – Optional accessory and loosen bolts Y.
- Set a square between the saw blade and guide M (Fig.1).
- Keeping the turntable at zero, move the guide to 90º on the square.
- Tighten bolts Y, assemble guides X and adjust handles V – Optional accessory.
4. ADJUSTING THE SAW BLADE WITH RESPECT TO THE WORKING PLANE
90º adjustment (Fig.2)
- Lower the head of the machine and lock with pin P (Fig.1a)
- Place a square between the base and the saw blade.
- Loosen lever O and adjust with bolt Z.
- Tighten the lock nut well to make sure that the position is fixed and tighten lever O.
5. VERTICAL PLANE LIMIT STOP ADJUSTMENT (0º -45º) (Fig.2)
- Lower the head of the machine and lock it with pin P (Fig.1a).
- Set the turntable to zero and lock.
- Set the head to 45º and lean a 45º square between the base and the saw blade.
- Loosen lever O and adjust using bolt Z.
- Regulate the 45º using bolt Z1 (Fig.1a), after releasing the lock nut.
- Tighten the lock nut to make sure that the position does not change.
OPERATION AND USE
1. CUTTING WITH THE BLADE AT 90º AND TURNTABLE TURNED
- Unlock the turntable K (Fig.1) by turning lever N (Fig.3) to the left.
- Turn the turntable with the handle, selecting the cutting angle required using the graduated scale R2 and index R (Fig.7), and lock again by turning lever N (Fig.3) to the right.
Note: there are pre-set cutting angles (0º, ±15º, ±22º30’, ±30º, ±45º) on which the turntable may easily be locked.
Note: if the version of the machine does not have the shaft locking system as described (the case of the first series manufactured), the saw blade must be blocked using a bar or a screwdriver in the hole of the saw blade, leaning against the firm structure of the machine.
2. REPLACING THE BRUSHES
The brushes must be replaced after every 150 - 200 hours of use or when they have reached a length of 5-6 mm. Go to an authorised service centre for this change.
3. REPLACING THE SUPPLY CORD Z2 (Fig.7)
Make sure that the supply cable is in a good state and if not, go to an authorised service centre for it to be changed.
