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 (F igure 1) is t he unit that
cuts the material and consists of a cast iron
base, blade support unit and guard,
transmission unit, and m otor. T he 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 cuttin g. 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.
Figure 1
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 r ecomm ended brands are DoAll
and Lenox. These coolants are ava ilable at your
local industrial distributor.

Electrical Requirements
When connecting the cold saw to the power
source outlet, the outlet must be properly
grounded to protec t the operator from electr ical
shock.
In the event of a malfunction or breakdown,
grounding provides a path of least res istance f or
electrical current to reduce the risk of electrical
shock. This m achine is eq uipp ed wit h an elec tric
cord having an equipment-groundin g conductoroutlet that is properly insta lled and grounded in
accordance with all local codes and ordinances.
This saw is equipped with a power cord.
Improper connection of the equipment groundin g
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 equipm ent -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-am p fuse or
circuit breaker.
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 occur s, there is t he potenti al
of a secondary hazard such as your hands
coming in contact involuntarily with the
rotating blade.
Electrical Connections
The J-F225 Cold S aw 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 pro ng, also s hown 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 q ualified elec trician. This ad apter
is not applicable in Canada. The green colored
lug must be fastened to the cover plate screw.
Important: The adapter illus trated i n F i g. B is f or
use only if you already have a properly
grounded two-prong receptacle. Do not modify
the plug provided-if it wil l 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 completel y 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.
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 EXTENSIO N CORD. Make sure
your extension cord is good condition. When
using an extension cord, be sure to use one
heavy enough to carr y the current your produc t
will draw. An unders ized cord will cause a dr op
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 num ber, the he avier
the cord.
