FIG3.04

4.1 Installation mounting
Unpack the machine.
• Determine where the sawing machine will be placed, in doing so take into account the feed and
discharge of materials, optional built-on accessories, maintenance and repairs.
• Remove the plastic plug from the saw head (fig. 4.01 B). If so required a lifting hook M20 DIN 580 can
be screwed into the hole.
• Race the saw unit - if necessary by means of hoisting equipment - on the machine base (cover at the
rear) and attach each other.
•Secure the machine on the floor. The necessary holes have already been made in the machine base.
• Install the handle in the saw head and lock it(fig 4.01 A).
• Install the 3 short handles in the boss of the machine vice,
• Install the stretcher in the clamp.
• Slide the plastic tube coming from the cooling pump onto the tap which is positioned on top of the
protective guard of the saw unit (fig 4.02A).
• Check on the level gauge of the saw head whether it contains sufficient oil. if necessary fill up (fig. 4.01,
see arrow).
• Install the cover at the rear of the machine base.
• Install the saw blade (see chapter 5.4)
4,2 Non-recurrent adjustment
This adjustment is concerning the LOWEST POSITION of the saw head. Follow the instruction on the
saw flange (fig. 4.03, see arrow). This instruction is also important when changing the saw blade.
4.3 Coolant
The use of proper cutting fluid is essential to obtain maximum efficiency from a band saw blade. The
main cause of tooth failure is excessive heat build-up. This is the reason that cutting fluid is necessary
for long blade life and high cutting rates. Cutting area and blade wheels should be kept clean at all time.
The rate of coolant flow is controlled by the stop valve lever (J) in Fig.4.02.which directs the coolant onto
the blade . The lever (J) is shown in the off position.Circulation system
Fill the tank with coolant. Use sawing coolant and absolutely NO cutting oil. recommends oils, available

from your dealer. The coolant must be diluted in wear in a ratio between 1:10 and 1:20, depending on the
kind of material. Add the oil slowly to the water while stirring it continually. The filler cap is positioned at
the rear of the machine base. The capacity of the tank is 10 litres.
The coolant circulates and for the larger part flows back into the tank. After some time
The coolant wiil be used up completely and the tank will have to be filled again. A filter is also
incorporated in the coolant circuit.
For general metal material (e.g. steel, copper), it is recommended to use BP-70 coolant.
Warning: Some material has fire hazards, e.g. Magnesium. Care must be taken when cutting such
material. Special coolant must be used for these material. Please get detailed information from
professional coolant supplier for special coolant.
-When adding coolant, attention should be taken that the coolant level should not access the line marked
on the coolant container.
4.4 Electricity
Have the electrical connections made by a qualified installer. Connect the machine in accordance with
the electrical diagram applying to your machine.
Electrical installations should be always performed by authorized electricians.
1)Make sure that the correct voltage is supplied to the machine.
2)Set up the electrical connections according to the attached circuitry. Connect the electricity on the
main line’s automatic circuit breaker.
3)Make sure that the circular saw has the correct rotation direction.
Warning: Note the earth screw!
Saw motor
Two-speed pole changing motors are suitable for one mains voltage only. Therefore check whether the
voltage indicated on the motor plate complies with the local mains voltage.
• Check whether the direction of rotation of the saw pitch corresponds to the arrow on the safety guard.
•If the motor rotates in the wrong direction two phases wires must be switched.
Overvoltage protection device shall be provided in the power supply line by the end user.
5 Operation
When operating at the first time, please check the back extension spring whether it is fastness, whether
it is fastness between handle switch and handle .You must move the head of machine and protection of
cutter up and down . Make sure they can convenient to open and close. Then you can operate it as
follow :
5.1 Selection of the sawblade
After years of research we recommend you to use only Time winner saw blades. These HSS saw blades
are of top quality and are made of the base material DMO 5, These saw blades have undergone a

Fig.5.01
Fig.5.0

special heat treatment which guarantees high wear resistance. Owing to the micros porous structure the
cutting oil is transferred quicker into the saw cut. This means longer life before resharpening and less
chance of cold welding. The quality of the saw blade is of great importance. The selection of the correct
pitch depends on the material to be sawn. The selection of the correct pitch and rake angle is of great
importance for the life of the sawblade.
5.2 Selection of pitch and tooth form
If the pitch is too small and the length of the cut too large, the cut material cannot be taken into the tooth
cavity. The chip wi!l get stuck in the tooth cavity, so that it is inactive in case of a second cut of the same
tooth. This can cause the saw blade to jam and break.A pitch which is too large will cause the sawing
tooth to hack as a result of which teeth can break free. For the sawing of profiles it must be taken as a
rule that at least two teeth of the saw blade are in cut.
Fig, 5.01 will help you determine the pitch for the material to be sawn.
Hint
If a short, hard jerk is felt during sawing and the saw starts jolting, do not continue. In such cases it is
almost certain that at one or more places a fine chip has fused away at the flank of the saw tooth.
This causes the saw to be slightly thicker at certain places. Remove the saw blade and remove the fused
material with a fine-grained, high-grade saw file.
Selection of the tooth form
Besides a well selected pitch the following factors, too, are of great importance to facilitate the correct
machining of the material (fig. 5.02)

Clearance angle (5 and rake angle 7 of the tooth have been selected correctly in view of the material to
be sawn, the principle is as foifows.

Form of tooth cavity large enough compared to the pitch.
A quick removal of the cut material and a correct depth and rounding of the tooth cavity are of the utmost
importance. The tooth cavity must be large enough for the removed chips to be bend as long as the tooth
is cutting. When the cutting tooth leaves the saw cut, the chip drops out of the tooth cavity.
The alternate saw (alternately bevelled edge) is often used for smalt pitches, especially up to 4mm.
The precutting and finishing teeth are used for larger, solid material, usually from pitch 4 mm onwards.
These teeth ensure that the chips are not all of the same length. If a chip were to be cut out tie normal
way, it would get hot, expand and become wider than the width of the cut. This wouid cause it to get
stuck, as a result of which the chip could not be removed from the cut. The finishing tooth must be
positioned 0.2 to 0.4 mm higher than the precutting tooth.
The larger the pitch, the higher the precutting tooth must be placed as compared to the finishing tooth.
Consequently, only special machines are suitable for regrinding these teeth. When the blade has lost its
cutting power, do not strain it. As a result the teeth may break off, which doubles the regrinding costs.
5.3 Sawing Capacity

5.4 Installing and replacing the saw blade
• Set the main switch in the off position.
• Put the saw head in the upper position.
• Open the guards (fig- 5.03A).
• Release the socket head screw M8 of the saw spindle
(fig. 5.03B) and remove the saw flange.
• Remove the saw blade.
• Carefully clean the saw spindle and the saw flange.
• Installing is done in reverse order. Pay attention to the direction of rotation of the sawblade. Make sure
the saw blade is placed flush against the flange of the saw spindle. Check the setting of the sawing
depth {see chapter 4.2}. Do not forget to close the safety guard.
5.5 Saw feed
Manual saw feed
The saw feed is determined by hand. The saw is lowered onto the material by means of the handle. Press the saw
blade firmly onto the material, without using unnecessary force. When the saw pressure is too high this can cause
the saw to break; when the saw pressure is too fow, the saw will rapidly go blunt.
5.6 Sawing speed
The saw speed wilt be selected by the switch (fig, 5.04A)
The following cutting speeds are possible:
CS-315 and CS-350 LOW SPEED SAWING SPEED POS.1:18.5M/MIN IN POS.2: 37M/MIN.
CS-315 and CS-350 HIGH SPEED SAWING SPEED POS.1:37M/MIN IN POS.2: 74M/MIN.
Every material has it's own cutting speed. Below advice for some materials;
18, & 36r/min > For steel alloy e.g. stainless steel
Fig.5.03
Fig 5.04

5.7 Clamping the material
It is of the utmost importance that the material is safely clamped in the double material vice, so that it
cannot tilt over or even move during sawing. In order to work efficiently, the material must always be
clamped in such a way that the contact surface of the saw and the material is as small as possible. For
instance, saw fiat material on its thinnest side; this will considerable shorten sawing times.
When very short pieces have to be sawn, and consequently only half of the material vice will be used, in
order to prevent it from pulling out of alignment, a piece of material of equal thickness must be clamped
in the other half of the vice. In this way the material is clamped tightly and evenly. Application of special
vice jaws Is recommendable for repetitive work
The sawing depth can be limited by means of an adjustable ring, see chapter 4.2
Mitre-sawing
Pull the clamping rod (fig. 5.06B) to the right and turn the sawing unit in
the required mitre position. The position can be read out on the scale
division (fig 5.06A). Then fasten the clamping rod again. Do not use
unnecessary force, a slight pull will suffice. Before clamping the
material, check whether the saw is running completely clear between
the jaws of the material vice. Place the sieel vice jaws as closely as
possible to the saw.
5.8 Cooling
Cooling is of great importance to the life of the saw blade. After thorough investigation it has been
established that the emuisifiable coolant oils absolutely prevents - among other things - the forming of
so-called buiit-ups (the fusing of cut material to the tooth point flanks). This will prevent a jolting saw,
which results in damage and breakage. Oils forms a lubricating film on the saw tooth points, so that, in
case of increased saw feed, the high pressure between chip and tooth (chip surface of the saw tooth) will
not lead to overheating of the saw. Here it is important that a correctly directed stream at the cutting
edges of the saw ensures an ample supply of coolant for the removal of chips and the elimination of
frictionai heat.
5.9 Start/stop
• Make sure the material has been fed.
• Check the sight-glass to see whether there is sufficient oil in the saw head. If necessary top up with BP
GRXP 680 (ISO) through the vent hole in the handle.
• Check the depth setting of the saw blade.
• Check whether the vice jaws are suited for this material.

Fig.6.03
A
• Adjust the material vice to the material
• Switch on the machine with the main switch.
Select the required speed.
• Open the coolant cock on the safety guard (not in case of atomized lubrication).
• Start machine with the switch on the pulling rod
6 Maintenance
6.1 General
Clean the machine after it has been used and provide rust protection by applying a protective oil.
Regularly remove the chips which gather underneath the vice jaws. In doing so use a thin, flat brush and
NEVER an air jet.
The gears, the worm and the worm gear are subject to wear. The moment the replacement of these
parts is due, depends on the usage. You can order a complete set, including instructions for disassembly
and assembly from your dealer. This kit is available from stock.
Regularly clean the coolant tank. This will considerable lengthen the life of the pump.
Check the condition of the oil filter in the cooling circuit, If the filter is severely polluted, it needs to be
cleaned or replaced.
Check the oil level in the saw head every week.
Check the oil level of the saw feed tank and refill if necessary (see chapter 6.3).
Check the oil bowl and the water separator every day. Refill the oil bowl with BP HLP 15 or a type of the
same quality.
Remove the water from the water separator of the air unit. With the PK-versions the glass can be
screwed off.
6.2 Lubrication
The gear box with the gear parts must be rinsed clean at least once per six months, depending on the
use of the machine. Loosen the plug at the bottom of the saw head and drain the oil, Rinse the unit with
petroleum and drain it thoroughly. Fill the unit with BP GRXP 680 (ISO); the 350-series with 1.1 litre.
Check the oil level on the sight-glass. If the saw head gets too hot while used continuously, the oil level in
the saw head may be too high.
Once every three months the grease nipples of the pivots of
the saw head must be greased with a universal grease.
The 350 and SCO-version has one grease nipple (fig. 6.03).
The threaded spindle, the guide rods of the material vice
and the guides of the machine bed must be oiled regularly.

6.3 Grinding the sawblades
It is only possible to work efficiently with circular sawing machine when the saw blade is reground in time.
When the saw has lost its cutting ability, do not try to continue sawing by puting the handle harder, for
this can cause teeth to break and the cost of regrinding doubled,
Regrinding should only be done on special machines, constructed for this kind of work. Besides that it is
advisable to check the saw optically in your own factory after they have been reground. In these optical
checks special attention must be paid to the rake angle and the clearance angle.
