OPERATION MANUAL
2.3 LIFTING INSTRUCTIONS
On the day that the machine arrives, make sure that a crane with sucient capacity is available
to unload the machine from the vehicle. Ensure access to the chosen site is clear and that doors
and ceilings are suciently high and wide enough to receive the machine.
To handle the machine, the slings should be positioned so the machine is level when lifted.
When using slings please take note of the sling angle and the loads that apply.
LIFTING POINTS
Use only the 4 eye bolts supplied with the machine to attach the slings. When lifting the ma-
chine only certied lifting slings should be used. Ensure that when lifting, the machine does not
tip over. Check that the lifting slings do not interfere with the hydraulic pipes or electrical con-
duits. Failure to follow these instructions could cause damage to the machine.
When the slings are at a 45° angle then each
sling is carrying the equivalent of 50% of load
weight. (Fig.2.1).
When the slings are at a 90° angle then
each sling will have a weight equal to 75%
of the load on each sling.(Fig 2.2)
Note! The manufacturer recommends not
to exceed 90° angle

OPERATION MANUAL
The unpainted surfaces of the machine have been coated with a waxy oil to protect them from
corrosion during shipment. Remove the protective coating with a solvent cleaner or a citrus
based degreaser.
Optimum performance from your machine will be achieved when you clean all moving parts or
sliding contact surfaces that are coated with rust prevented products.
Hafco advise to avoid chlorine based solvents, such as acetone or brake parts cleaner, as they
will damage painted surfaces and strip metal should they come in contact. Always follow the
manufacturer’s instructions when using any type of cleaning product.
3.2 CLEAN - UP
3. SETUP
3.1 SITE PREPARATION
When selecting the site for the machine, consider the largest size of workpiece that will be
processed through the machine and provide enough space around the machine for operat-
ing the machine safely. Consideration should be given to the installation of auxiliary equip-
ment. Leave enough space around the machine to open or remove doors/covers as required
for the maintenance and service as described in this manual.
It is recommended that the machine is anchored to the oor to prevent tipping or shifting. It
also reduces vibration that may occur during operation. The machine should be mounted on
a reinforced concrete oor with a minimum of 150mm thickness. The oor must be able to
support the weight of the machine any workpiece that is to be worked.
3.3 MACHINE MOUNTING OPTIONS
Although it is not required Hafco recommends that you secure
your machine to the oor. Masonry anchors with bolts are the
best way to anchor machinery, because the anchors sit ush
with the oor surface, making it easy to unbolt and move the
machine later, if needed. (Fig. 3.1) Other methods of mounting
is the use of machine mounts which also help with the levelling
of the machine and isolating vibration. (Fig.3.2)

OPERATION MANUAL
Place the machine near an existing power source. Make sure all power cords are protected from
trac, material handling, moisture, chemicals, or other hazards. Make sure there is access to a
means of disconnecting the power source. The electrical circuit must meet the requirements for
240V.
NOTE : The use of an extension cord is not recommended as it may decrease the life of electrical
components on your machine.

(Full load current rating is also on the specication plate on the motor.)
3.4 MACHINE LEVELING
To set your machine up so that it operates to optimum performance, apply the following
procedure
After your machine has been anchored to a concrete slab oor, it then needs to be leveled.
Loosen the hold down bolts and place a level on the surface of the working table. Metal shims
need to be placed under corner of the base of the machine until level. Once level then tighten
the hold down bolts. (Fig. 3.3).
The machine must not rest on supports
other than those dened in Fig. 3.1

OPERATION MANUAL
The full-load current rating is the amperage a machine draws when running at 100% of the out-
put power. Where machines have more than one motor, the full load current is the
amperage drawn by the largest motor or a total of all the motors and electrical devices that
might operate at one time during normal operations.
Full-Load Current Rating for these machine at 240V is 6.0 Amps
It should be noted that the full-load current is not the maximum amount of amps that the
machine will draw. If the machine is overloaded, it will draw additional amps beyond the
full-load rating and if the machine is overloaded for a long period of time, damage, overheating,
or re may be caused to the motor and circuitry.
This is especially true if connected to an undersized circuit or a long extension lead. To reduce
the risk of these hazards, avoid overloading the machine during operation and make
sure it is connected to a power supply circuit that meets the requirements.

LIFTUP & SWIVEL HANDLES
The machine is tted with two handles. One to help
when lifting the head and then both handles are used
to help control the head when it needs to be swiveled.
(Fig. 4.2)
TENSIONING THE SAW BLADE
Check the tension of the saw blade. The tension in the
saw blade is correct if the middle of the blade between
the supports, can be pushed down no more than 3 mm
with a force of approximately 50 N.
The tension of the saw blade can be adjusted by means
of the hand wheel. (Fig.4.4)
QUICK ACTION VISE
The band saw is tted with a quick action vise that
allows for the quick tightening or releasing of material
in the vise. The quick action has a limited stroke so the
hand wheel is required to move the vise jaws closer
together.

LENGTH STOP
The machine is tted with an adjustable length stop.
(Fig.4.5)
To install the length stop
1. Screw the threaded rod into the base of the machine
and tighten the lock nut.
2. Slide the length stop onto the rod
3. Measure the distance from the blade to the face of
the length stop and move the length stop in or out
until the correct measurement is achieve.
4. Tighten the length stop on the rod.

OPERATION MANUAL
Fig. 4.6
4.2 COOLANT SYSTEM
The sawing movement produces high temperatures
at the edge of the blade due to the friction generated.
The blade must therefore be cooled during operation.
Using a suitable lubricant or cooling agent leads to
better results and longer saw blade life. (Fig. 4.6)
The coolant is delivered through two taps situated on
the blade guide assemble.
To start the coolant turn the switch on the control panel
(D in Fig.4.1) and press and hold the trigger switch, then
adjust the taps. (Fig.4.7 & 4.8) To much ow at the nozzle
will make a mess of the work area and cause it to be-
come unsafe, but to little will cause the blade to over-
heat, causing the blade teeth to load up and break.
Fig. 4.7
Soluble Oils
The most common of all water-soluble cutting uids, soluble oils (also known as emulsiable
cutting uids) are typically 50 percent oil before dilution. When mixed with water, they form a
milky emulsion that is an excellent choice for general purpose cutting. They are, however, prone
to “Monday morning stink”–a foul-smelling odor from microbiological growth of fungus and
bacteria that can grow in your coolant sump if not properly maintained.
Synthetic Fluids
As you can probably guess from the name, synthetics contain no oil, using various polymers
and chemical compounds to replicate oil’s natural lubricity. They reject tramp oil, so they tend
to be the cleanest of all cutting uids, but are often the least lubricious. They are commonly
used in grinding applications, but proponents suggest that synthetics can be tailored to
virtually any metalworking operation, especially metal cutting band saws.
HAFCO recommend that Synthetic cutting oil be used available in two sizes.

4.4 SETTING THE DOWN FEED
The down feed is the speed at which the saw blade cuts
through the workpiece. The rate at which the bow saw
drops is controlled by a valve that can be adjusted to in-
crease or decrease the speed that it moves.
To set the feed rate raise the bow to the highest position
and hold it in place with the feed ON/OFF lever. (Fig. 4.11)
Adjust the feed rate dial to the desired feed rate.
Start the saw and coolant pump and begin cutting.
Examining the chips is the best indication of the correct
blade speed and feed rate .
A. This is the correct chip shape. The chip should be a
silver colour. If the chips are blue then decrease the
feed until they are silver. The shape also indicates that
the blade TPI is correct.
B. This shape is in-correct. The shape is compressed and
indicates that the chip is too big for the tooth gullet.
This is the most common cause of broken teeth.
Either decrease the feed or change to a larger TPI.

The band saw is tted with the capacity to cut angles with the head being able to be
swiveled up to 60° to the right. To set the angle of the cut, raise the bow saw to the high-
est point and hold by setting the ON/OFF lever to OFF.(Fig.4.11). Move the swivel lock lever
(Fig.4.12) to the right and rotate the head until the scale (Fig.4.13) is at the angle required. Move
the swivel lock lever to the left to lock the head. The machine is tted with swivel a head stop at
60 degrees. (Fig.4.14)
NOTE: Please note that the scale (Fig.4.13) is for reference only and if the angle is required to be
very accurate then the angle should be checked with a protractor after the cut.

4.8 BLADE SELECTION
Band saw tooth size is determined by the size of the cross section to be cut. In general cutting
thinner sections requires more teeth per inch, thicker sections require coarser pitches, or less
teeth per inch. To select an appropriate tooth size please refer to the table immediately below
unless material to be cut is a tube, in which case refer to the larger table below. For general pur-
pose cutting use a constant pitch blade, for more aggressive production cutting of harder to cut
materials use a variable pitch blade.

5.3 CHANGING THE COOLANT
Fig. 5.5
This band saw is tted with a coolant system that extends
the life of the band saw blade by lowering the temperature
of the blade and the workpiece.
To maintain the eectiveness of the cutting it is important
to keep the coolant clean, therefore the coolant should be
changed every 1000 hrs.
To change the coolant.
1. DISCONNECT THE MACHINE FROM THE POWER SUPPLY
2. Place a container under the drain and remove the
drain plug on the side of the machine. (Fig 5.5)
3. Once the coolant is empty remove the two screws that
secure the screen on the top of the reservoir, and
remove the screen. (Fig.5.6)
4. With clean rags, wipe out the bottom of the coolant
reservoir until it is clean and free from dirt or metal
chips.
5. Replace the screen and drain plug and rele with clean
coolant.
