Location of safety
Covers
-Grey metal shield covering the blade.
-Blue plastic shield covering the blade.
-Black plastic cover, covering the electrical supply box.
Electrical equipment
-According to European Standard “CENELEC EN 60 204-1” which simulates modifications,
publication (IED 204-1)
-The electrical equipment ensures protection against electric shock as a result of direct or indirect
contact. The active parts of this equipment are housed in a box so that access is limited, the screws
can only be removed with a standard screwdriver.
-This equipment is protected against splashes of water and dust.
-This machine has been tested in conformity with EN 60204.
Recommendations for use
-This machine has been designed to cut metal building materials with different shapes, profiles
used in workshops and mechanical structural work.
-Only one operator is needed to use the machine.
-Before starting each cutting operation, ensure that the part is firmly gripped in the vice and that
the end is suitably supported.
-Do not use cutting blades of a different size from those stated in the cutting capacity section (next
page).
-If the cutting blade gets stuck in the work piece, release the blade ON button immediately, switch
off the machine, and open the vise slowly. Remove the part and make sure that the cutting blade
and/or its teeth are not damaged or broken.

-Place both large pieces of the pedestal next to each other like in Illustration 4 on page 5.
- Take piece 4 and place between piece 1 and 2, as you will notice there are tabs on the sides, Put
these tabs in the holes of piece 1 and push down, the two pieces will snap together (see illustration
8 & 9). Do the same with piece 3.

-Remove the shipping bolt (see illustration 18) and screw the handle in the hole. There is a white
plug that comes out of the handle, plug this into its receptacle located on the side of the electrical
box (see illustration 19). There is a lever on this attachment move this to the closed position as
seen on illustration 19.

Anchoring The Machine
-Position the machine on a firm cement floor; keep a minimum distance of 2 1/2 feet from the
wall. Mount to the floor as shown in diagram
3.

-Before connecting the machine to the main power, make sure that your installation has a
disconnect box.
-The machine is not provided with an electrical plug, the customer must provide a suitable plug for
the machine. See diagram below for wire connection.
Operating your Cold Saw cut 250
-Mix the coolant that came with the machine (Trim Sol) at a 10:1 ratio, add about a half gallon of
mixed coolant in the machine bed.
-Place the material to be cut in the vice (1) and clamp the material in place by turning the hand
wheel (2) clockwise.
-Turn the power switch clockwise to the on position (illustration below).

-Be sure that the blade is rotating in the correct direction indicated (the blade will rotate clock
wise, be sure the blade is on correctly, also see changing the blade page 12) and check to make
sure the coolant is on.
-The machine is now ready to cut the material. Keep in mind that the cutting speed and the type of
blade, combined with a suitable descent of the head are of decisive importance for cutting quality
and machine performance.
- When starting to cut with a new blade, be sure to take out the back lash (see changing the blade)
on the blade, in order to safeguard the blade life and efficiency, the first two or three cuts must be
made while exerting a slight pressure on the part, so that the time taken to cut is about double the
normal time. Grip the handle and press the button, slowly move the head in the down position and
begin to cut the material. When you are done cutting the material, release the blade “on button”
and move the head in the up position.
Changing the blade
Warning!!!!! Before performing the following operations, the electrical supply must be
LOCKED OUT.

-Move the head to the upright position and remove the blue safety guard bolt (5mm Allen wrench
see illustration 20), move the safety guard in the back position.

-Always wear gloves when handling the cutting blade or any sharp object.
-Use the 10mm Allen wrench to remove the blade bolt (see illustration 20), this is a left hand
thread; turn it clockwise to loosen the bolt. Slip off the bolt and the flange that holds the blade on.
-When placing on a new blade be sure to clean all surfaces and that the cutting teeth are facing in
the down position (the blade turns clockwise), line the holes up on the blade with the holes on the
motor side (Clean both sides of the flange), put the flange back on, making sure the flange pins are
in line with the flange pinholes.
-Screw the blade bolt back in turning it counter clockwise, before tightening the blade be sure to
remove the back lash by pulling up on the blade in the reverse direction and holding it while
tightening the blade.
-Screw in the safety guard bolt and you are finished.
Routine maintenance
If the following operations are neglected, the result will be premature wear of
the machine and poor performance.
Daily maintenance
-General cleaning of the machine, remove accumulated shavings.
-Keep coolant level full.
-Check for blade wear
-Lift the head to the up position, to avoid stress on the return spring when not is use
-Check functionality of the safety shields.

Weekly maintenance
-Remove metal shavings from the coolant tank
-Clean and grease the screw and the sliding guide of the vice.
-Clean the blade housing
-Sharpen the blade
Monthly maintenance
-Check tightness of the screws on the motor, the pump, the jaws and safety guard
-Check that the safety shield is not broken
-Grease the head hinge pin.

How to change the oil in the gearbox
-Disconnect machine from the power supply
-Change the oil in the reduction unit using gear lube 80/90. We recommend MOBIL SHC635.
- Remove the handle and the plug coming from the handle to the electric box.
-Unscrew the sight level gauge; this will drain all the oil in the gearbox. Use a bucket to catch all
the oil from the gearbox.
-When oil stops coming out of the sight level hole, screw the sight level gauge back into the hole.
-Fill gearbox with 80/90-gear oil. We recommend SHC 635 MOBIL when refilling the gearbox
be sure to fill only to the middle of the sight level gauge when the cutting head is sitting level.
-Screw handle back in hole and connect the Plug coming from the handle.
Oil disposal
-The disposal of oil and coolant products are controlled by strict regulations, follow local rules and
regulations to dispose of properly.

Choosing a blade
First of all, the pitch of the teeth must be chosen, suitable for the material to be cut, according to
this criteria:
-Parts with a thin and/or variable section such as profiles, pipes and plate, need fine toothing, so
that the number of teeth used simultaneously cut.
-Parts with solid sections need wide spaced toothing penetration.
-Material made of soft plastic, light alloys and mild bronze also requires coarse toothing.
-Attached to the on/off switch on the machine you will find a blade pitch calculator (Part number
71756) with instructions on how to use it.
Troubleshooting
This lists the probable faults and malfunctions that could occur while the machine is being used
and suggests possible remedies for solving them.
PROBLEM
PROBABLE CAUSE REMEDY
Tooth breakage Too fast advancement
Wrong tooth pitch
Low quality blade
Ineffective gripping of the vise
Previously broken tooth left in
material
Insufficient coolant
Blade is on backwards
Decrease advancement, use
less cutting pressure
Choose a different blade
Choose a better quality blade
Tighten vise if necessary
Remove all pieces from
material
Check coolant level, Add more
if necessary
Turn blade around
Premature disk wear Incorrect blade
Insufficient coolant
Change blade for one that has
more or less teeth
Check coolant level, add more
if necessary
Chipped disk Flaws in the material
Wrong tooth pitch
Reduce the cutting pressure
and/or advancement
Change blade for suitable
blade (use blade pitch
calculator)

Noise test
In accordance with point 1.7.4f of the Machines Directive EEC 89/392
-The microphone was located close to the operator’s head at medium height.
-The equivalent continuous acoustic pressure level was 77,6dB (A).
-The maximum level of the weighted instantaneous acoustic pressure C was always less than 130
dB.
NOTE: With the machine operating, the noise level will vary according to the different materials
being processed. The user must assess the intensity and if necessary provide the operators with the
necessary personnel protection, as required by law 277/1991.
