Introduction
The JET Model J-F225 Cold Saw is a pendulum bench saw designed for cutting metals. Operation is manual: after turning on the electrical power supply to the machine and clamping the workpiece in the vice, the operator starts the blade by pressing the micro switch located on the control lever; he then moves the head downwards in order to cut the material; after completing the cut, the cutting head returns to position ready for a new cutting cycle. The Model J-F225 can perform miter cuts up to 45° to the left.

Features
In this section, refer to Figure 1 except where otherwise specified.
Miter Cutting Head
The miter cutting head (Figure 1) is the unit that cuts the material and consists of a cast iron base, blade support unit and guard, transmission unit, and motor. The depth of cut is set by adjusting the depth cut stop. The miter cutting head swivels and can be adjusted from
0–45º.
Miter Positioning
The cutting angle (miter position) is manually adjusted and described in Performing Angle
Cuts on page 10.
Self-centering Vise
The self-centering vise holds the work piece in place during cutting. The work piece is secured in the vise by turning the vise handle.
Trigger Handle
The trigger handle is located on the operating
lever used to raise and lower the saw. It contains a micro-switch (Figure 9), which starts the saw when pressed.
Flood Coolant System
Coolant is dispensed directed onto the saw blade from a coolant fitting on the upper blade guard. Coolant is provided through tubing from the coolant pump mounted on the back of the motor casing.
The coolant flow control valve (Figure 2) is located on the back of the saw. Adjust the valve to achieve desired flow. Flow starts when the switch on the machine is turned on and the
micro-switch in the trigger handle is depressed.
Releasing the micro-switch stops coolant flow.
This coolant system can operate with either a soluble oil base coolant or water-soluble synthetic coolant. Coolant should be changed regularly. Some recommended brands are DoAll and Lenox. These coolants are available at your local industrial distributor.

Electrical
Electrical Requirements
When connecting the cold saw to the power source outlet, the outlet must be properly grounded to protect the operator from electrical shock.
In the event of a malfunction or breakdown, grounding provides a path of least resistance for electrical current to reduce the risk of electrical shock. This machine is equipped with an electric cord having an equipment-grounding conductoroutlet that is properly installed and grounded in accordance with all local codes and ordinances.
This saw is equipped with a power cord.
Improper connection of the equipment grounding conductor can result in a risk of electric shock.
The conductor with insulation having an outer surface that is green (with or without yellow stripes) is the equipment -grounding conductor.
If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.
Plug power cord into a 110-120V properly grounded outlet protected by a 14-amp fuse or circuit breaker. the plug provided-if it will not fit the outlet, have the proper outlet installed by a qualified electrician. Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded.
Before plugging into the power source, be sure that power switch is in the OFF position.
Do not touch the prongs of the power cord plug when plugging or unplugging to or from an outlet.
If improperly grounded, this power tool can cause serious injury from electrical shock, particularly when used in damp locations or near plumbing. If an electrical shock occurs, there is the potential of a secondary hazard such as your hands coming in contact involuntarily with the rotating blade.
Electrical Connections
The J-F225 Cold Saw is rated at 115V, 1Phase and is designed for use on a circuit with an outlet that looks the one shown in Fig. A. and have a grounding prong, also shown in Fig. A. A temporary adapter (Fig. B) may be used to connect the plug to a two-prong receptacle
(Fig. B) if a properly grounded outlet is not available. A temporary adapter should only be used until a properly grounded outlet can be installed by a qualified electrician. This adapter
is not applicable in Canada. The green colored lug must be fastened to the cover plate screw.
Important: The adapter illustrated in Fig. B is for use only if you already have a properly
grounded two-prong receptacle. Do not modify
9
Extension Cords
Use only three-wire extension cords that have three-prong grounding type plugs and threeprong receptacles that accept the tool's plug.
Replace or repair damaged or worn core immediately.
USE PROPER EXTENSION CORD. Make sure your extension cord is good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 1 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage, The smaller the gage number, the heavier the cord.

Blade Selection
When using the J-F225 cold saw, it is important to select the correct type of blade for the material to be cut. This section explains the limitations and specific applications of the different types of blades.
General characteristics:
Fine Tooth Pitch – used for thin wall materials such as sheet steel, tubes and profiles
Coarse Tooth Pitch – used for large crosssections – for soft materials (aluminum alloys and soft alloys in general).
Determining proper tooth pitch
Proper tooth pitch depends on: a) the size of the section; b) the hardness of the material; c) wall thickness.
Solid sections call for discs with a coarse tooth pitch, while small cross-sections require blades with finer teeth. This is because when cutting walls of small crosssection (1–7 mm) profiles, it is important that the number of teeth actually making the cut should not be too small, otherwise the effect obtained will be one of tearing rather than of chip removal, leading to a large increase in shearing stress. On the other hand, when cutting thick materials or solid sections using an excessively fine tooth pitch, the chip collects as a spiral inside the gullet, and since fine tooth pitches have small gullets, the accumulated chip will exceed the gullet capacity and press against the walls of the workpieces, resulting in poor cutting (same situation with soft materials), greater shearing stress and hence breakage of the blade.
Table 2
A larger pitch should be chosen when, as a result of the shape of the piece to be cut, the cross-section at any given point exceeds the average cross-section given above.
Cutting and feeding speed
The cutting speed, in m/min, and the head feeding speed, in cm
2
/min, are limited by the amount of heat generated near to the points of the teeth. If the head feeding speed is too high, the cut will not be straight in either the vertical or the horizontal plane. As we have already said, the cutting speed depends on the strength
(kg/mm
2
) and hardness (HRC) of the material and the dimensions of the thickest section. The feeding speed depends on the cross-section of the material. Solid or thick-walled materials
(thickness>5mm) can therefore be cut at high speed providing there is sufficient swarf removal by the blade, while thin-walled materials such as tubes or thin profiles must be cut with a low feeding speed.
A new blade requires a break-in period, during which time about half the normal feeding speed should be used.
Coolant
The cooling fluid ensures that the blade teeth and material in the area of the cut do not overheat. The fluid must be an excellent lubricant so as to prevent abrasion of the teeth and welding of the chips to the teeth themselves
(seizing).
14
Troubleshooting Blade and Cutting Problems
Teeth breaking
Rapid tooth wear
Broken blade
Spindle motor will not turn
Solution
Incorrect lubricant/coolant fluid Ensure proper coolant flow.
Material too hard
Check the cutting speed, feed speed and air pressure parameters and the type of blade you are using.
Disc not worn--in correctly
Disc with excessively fine tooth pitch
With a new blade it is necessary to start cutting at half feeding speed. After the wearing--in period (a cutting surface of about 300 cm
2
for hard materials and about
1000 cm
2
for soft materials) the cutting and feed speeds can be brought up to normal values
The swarf wedges into the bottom of the teeth causing excessive pressure on the teeth themselves
New blade inserted in a partially completed cut
Work piece not clamped firmly in place
Feed speed too slow
Cutting pressure too high
Blade speed too high
Insufficient coolant
Incorrect fluid concentration
Material defective
The surface of the cut may have undergone work hardening. When starting work again, use a lower cutting speed and head feed speed. A tooth from the old blade may be left in the cut: check and remove before starting work again.
Any movement of the work piece during cutting can cause broken teeth: check the vise, jaws and clamping pressure.
The blade runs over the material without removing it: increase feed speed.
Reduce cutting pressure.
The teeth slide over the material without cutting it: reduce the blade speed.
Check the coolant level and clean coolant lines and nozzles.
Check and use the correct concentration.
The materials may present altered zones either on the surface, such as oxides or sand, or in section, such as under-cooled inclusions. These zones, which are much harder than the blade, cause the teeth to break: discard or clean these materials.
Feed speed too high
Teeth in contact with material before starting the cut
Insufficient coolant
Electrical power supply
Transformer
Contactor
Thermal relay
Motor
Reduce blade speed.
Always check the position of the blade before starting a new job.
Check the coolant level and clean coolant lines and nozzles.
Check: the cables, plug and socket. Also check that the motor connections are in place.
Check that the voltages are present both on the input and output. Otherwise replace.
Check that the phases in it are present both on the input and output, that it is not jammed, that it closes when powered and that it is not causing short circuits.
Change if any of these problems are found.
Make sure it is closed, i.e. check that the phases are present in input and output that it is not causing short circuits and responds when the reset coil is closed. If it has tripped to protect the motor, check the amperage setting, reset, and check the motor. Change if necessary.
Check that it has not burnt out, that it turns freely and that there is no moisture in the connection terminal board box. The winding can be rewound or replaced.
