4) Prior to install or services the machine, please read and understand the
maintenance manual.
5) To service the machine, it must be done only by competent and trained
personnel.
NOTICE: The following safety instructions are general recommendations for
most common operations on a milling machine.
Additional safety measures may be required for your particular application.
Therefore, manufacturer makes no warranty or representation as the absolute
correctness of sufficiency of the instructions.
1-1. General Safety Instructions For Operating The Machine
1) The best defense against injuries on a milling machine is to be alert. Never
initiate a machine function unless you completely understand what the function
will cause the machine to do.
2) Never operate the machine with any cover and shield opened or removed.
3) Never reach into the work area when the spindle is rotating or if the machine is
still in running mode.
4) The functions of the machine make it impossible to eliminate all dangerous area.
Be particularly aware of the following cautious points:
* Spindle rotation
* Electric cabinet and power source
* Table and saddle movement

- 6 -
5) Keep the machine and area around it clean and well lighted. Never allow chips,
coolant or oil to remain on the floor. Do not leave loose objects on and around
the machine.
6) Clothing :
* Wear safety glasses with eye shields at all times. Protect your eyes. Never use a
compressed air house to remove chips from a machine.
* Never wear loose fitting clothing. Remove all jewelry (rings, watches,
necklaces…etc.) since they can be trapped in mov ing parts of the machine.
* Gloves are easily trapped by moving parts. Take them off before turning the
machine on.
* Always wear safety shoes with steel toes and oil-resistant soles.
* Wear a safety helmet when working near overhead hazards.
* If operator has long hair, the hair should always be tucked under a cap or tied
back up.
7) Milling machine are designed to be run by one person. Persons other than the
designated operator should stay out of the machine area during the operation.
8) Take care, not to bump or accidentally touch the machine control. Doing so can
initiate an unintended machine movement which could cause an injury or a
wreck.
9) Do not paint, alter, deface or remove any warning plates from the machine.
10) Report any loose, worn or broken parts to your supervisor. The same action
should be taken if any unusual noise or machine action occurs.
11) Never operate the machine after taking strong medication, using non-
prescription drugs, or consuming alcoholic beverages. Persons with illness,
which might cause dizziness or fainting, should never operate this machine.
13) The electric components are protected from normal moisture resulting from
humidity use of water base soluble coolant, etc. Do not, however, use water hose to
clean the machine or the area around it.
14) Never touch a machine control device or electrical component when your hand
is wet. Keep flammable liquids and materials away from the work area and chips.
15) Never clean up chips while the machine is running or is in automatic mode.
16) Do not file work pieces while spindle is still rotating under power.
17) At the end of the work day the machine should be placed in “power off” mode .
18) When restarting a machine after it has been shut down, please always assume it
has been tampered with. Recheck all phases of the job as though you were running
the first piece.
19) Never switch-on spindle until hands, feet, and body are well clear of the work
area.

- 7 -
20) Coolant and oil can make surfaces on the machine slippery. They can also
present an electrical hazard if the machine has power on. For these reasons, please
do not stand on any part of the machine at any time.
1-1-1 Safety instructions for work holding
1) Never run a job on this machine until you are 100% sure the work piece is being
held in such a manner as withstand the centrifugal force from rotation and
cutting forces of the tooling. If there is any doubt, whatsoever, please consult
with your supervisor.
2) A vise is the most common work holding device used on this machine. Some of
the factors affecting the holding device on this machine.
The factors which affect the holding ability of a vise are:
* Clamping force of the jaws on the vise
* Rotational speed of the spindle
* Type of jaw surface (serrated, smooth, etc.)
* Area of vise holding and configuration of the work piece…shape, weight and
balance.
* Vise’s weight and location
3) With air or hydraulic actuated power vise (optional accessory), make sure the
jaws are gripping the work securely before they reach the end of their travel.
When using a power vise, please check the hydraulic or air pressure before
every operation. Low air pressure will diminish jaw-gripping force, which may
allow the work piece to fly out of the jaws. Excessive pressure can also damage
a power vise, which could cause a loss of jaw force. The gripping force of a
power vise can be diminished as much as 50% because of lacking of lubrication
or periodic cleaning. Components of a vise are subject to wear and damage
which also can lessen gripping force. Oil the vise at the beginning of every
shift. Please use only the vise manufacturer’s recommended lubricant.
A. A weekly examination of the condition of the vise should be made. This
examination should include the measurement of jaw clamping force with a
jaw-force gage to insure that the vise is functioning as it is intended.
B. Refer to manufacturer’s manual for vise and cylinder for any other
maintenance requirements. As the cutter’s R.P.M. increase the gripping
force of the jaws on the vise decreases. The larger the vise opening the
more loss becomes. Various types of vise’s jaws are serrated contact
surfaces on work piece. Improper usage could cause serious injury or death.
Remember-vise gripping a work piece safely involves many variables. If
you have the slightest doubt regarding the safety of your set-up for a job,
please consult with your supervisor.
4) Never operate spindle-mounted accessories over their rated speed. If the
cutting tool or accessory is not supplied by the original maker, please verify the
safety operating speed with the manufacturer.

- 8 -
5) Always be sure the tool holder or accessory is located correctly on the spindle
taper and it is securely pulled to the face of the spindle.
6) Be sure any item bolted or clamped to a vise or fixture is securely fastened
before starting the spindle.
7) Proper lifting equipment should be used for heavy vises, fixtures, and work
pieces.
8) Always be aware of that closing vise’s jaws may trap fingers or hands.
9) The same safety instructions that apply to power vises also apply to manual
operated vises. The following additional precautions should be taken when using
a manual vise :
A. Always use spring-loaded, self-ejecting type safety wrenches.
B. Never put an extension bar on a vise wrench or hit with hammer.
C. Always slightly tap the workpiece after clamping with the jaws. This is
done to make sure workpiece is securely tightened to the vise. Without
confirming the tightness, the workpiece may fly out of the vise if the
cutting force is too greater!
10) If a work piece is extended from the vise a distance of 3 to 4 times of its
capacity, without being supported by other means, poor cutting finish will normally
occur. Under no circumstances extend an unsupported workpiece more than this
amount without supporting with other devices. Doing so can cause the part to bend
or break or flying out!
1-2. Maintenance Safety Instruction
WARNING
High voltage is used to power the machine; only authorized electricians should
service any electrical component failure. Disconnect main power and lock it in off
position before attempting any repair. Tag disconnect switch “DO NOT START”
1) Read and understand safety instructions for machine operation before servicing
this machine.
2) Know all points where high voltages are present on this machine and in
electrical boxes.
3) Residual voltages can exist in electrical cabinets for a period of time after power
has been turned off. Check any component inside cabinet with a voltmeter
before touching.
1-3. Installation Precautions
To ensure the safe operation of the milling machine, note the following during
installation.

- 9 -
Wiring
1) Be sure to use electrical conductors with performance ratings equivalent or
superior to those described in the Maintenance Manual.
2) Do not connect to the same power distribution panel that is intended for devices,
which can cause line noise, such as, welders and high frequency quenching
machines.
3) Arrange for a qualified electrician to connect the power lines.
1-3-1.Grounding
Use a grounding wire with a cross section of more than 14 mm and a resistance to
ground less than 100 ohms.
This wire size should be greater than AWB (American Wire Gauge) No. 5 and SWG
(British Legal Standard Wire Gauge) No.6.
Generally, the milling machine should be ground to a separate grounding rod. If an
independent ground cannot be provided for the machine, prepare the ground
connection as follow:
1) Connect a single conductor to its grounding terminal. This will avoid possible
serious accidents resulting from ground currents, which might otherwise flow
thru the milling machine and damage an electrical component or device within
the electric cabinet.
2) Be careful when using concrete reinforcing rods as grounding points. These
reinforcing rods often are used to ground equipment because they usually offer a
resistance to ground of less than 100 ohms. In doing so, please make the
connections as follow:
A. Do not use the same grounding-reinforcing rod or grounding terminal for
other devices, since this could lead to line noise such as produced by
electric welders and high frequency quenching machine.
B. Use a grounding terminal with an adequate electrical performance rating and
is durable in usage.
3) A separate grounding wire should be used, one whose length is as short as
possible.
4) Check the resistance to ground by actual measurement. This should measure less
than 100 ohms if the single device is connected to its own grounding rod.
Desirable independent grounding:
Earth resistance: Less than 100 ohms

- 10 -
Common grounds:
Never ground equipment as
shown in the lower figure (FORBADE!) :
(Wrong)
1-3-2.Environmental conditions
Generally, the machine will be installed at the places with the following conditions.
However, these may change over a period of time or in response to seasonal
changes.
1) Supply voltage : 90% to 110% of nominal supply voltage
2) Source frequency : ±2hz of nominal frequency
3) Ambient temperature : 0℃to 45℃(32℉to 113℉)
4) Relative humidity : Less than 80%
Temperature changes should not cause condensation.
5) Atmosphere: Free from excessive dust, acid fumes corrosive gases and salt.
6) It should be avoided to expose the machine to direct sunlight or heat rays which
can change the surrounding temperature.
7) Avoid exposing the milling machine to abnormal vibration.
***If it is difficult to observe or meet these conditions, please contact us
immediately.
1-4. Safety Precaution
This machine is provided with a number of safety devices to protect operator and
equipment from being injured and damaged. Operators should not, however, rely
solely upon these safety devices but should operate the machine after fully
understanding what special precautions to take by reading the following details
thoroughly.
Resistance to ground = 100 the
number of devices connected to the
grounding (Ω)

- 11 -
Basic Operating Practices
DANGER
1) Some control panels, transformers, motors junction boxes and other parts have
high-voltage terminals, these should not be touched or a severe electric shock
will be sustained.
2) Do not touch a switch with wet hands. This, too, can cause an electric shock.
WARNING
1) The emergency stop push-button should be well known so that it can be operated

1) Be sure the instruction manual or the operation manual is fully understood.
Every function and operation should be completely clear.
2) Use safety shoes, which are not, damageable by oil, safety goggles with side
covers, safe clothes and other safety protection.
3) Close all electric cabinet doors and table guarding doors (optional) before
switching the machine on.
CAUTION
1) The power cable from the factory power fuse blocks to the machine’s main
circuit breaker should have a sufficient cross-sectional area to handle the electric
power used.
2) Cables which have to lie on the floor must be protected against chips so that
short circuit will not occur.
3) Each sliding part must be freshly lubricated before starting to operate the
machine after unpacking or keeping the machine idle for a long period (several
months or more). For initial lubrication and so forth, please keep lubricating oil
pump working until oil oozes out from wipers. Contact manufacturer’s service
station in connection with what procedure should be taken since it depends on the
type of machine.
4) Oil reservoirs should be filled to indicate levels, check and add oil, if necessary.
5) For lubricating points, oil brands and appropriate levels, please see the
lubrication chart at later section.
6) Switches and handles should operate smoothly.
7) Check the coolant level, and add coolant, if necessary (only for 6VK).
8) When switching the machine on, connect the factory feeder switch to the
machine’s circuit breaker, and then turn the power switch to the ON position in this
sequence.
1-4-2. Routine inspections

1-4-3. Warm-up
1) Warm up machine, especially the spindle and lubrication pump by running them
for 10 to 20 minutes at about half or one-third the maximum speed indicated on the
manual.
2) This self-warming-up program should activate each machine’s component t o
operate. At the same time please check their operations’ correctness.
3) Be particularly careful to warming up the spindle, which can turn up to 4500rpm.
If the machine is used for actual machining immediately after spindle start,
following a long idle period, sliding parts such as bearings may be worn due to lack
of lubrication oil. Also, thermal expansion of the machine’s components can
jeopardize machining accuracy. To prevent this from happening, always warm the
machine up.
1-4-4.Preparations
WARNING
1) Tooling should conform to the machine specification and dimensions’ types.
2) Seriously worn-out tools can cause injuries. Replace all such tools with new

11) Use a brush to remove chips from the tool tip not with bare hands.
12) Stop the machine whenever installing or removing a tool.
13) Whenever machining magnesium alloy parts, please wear a protective mask.
CAUTION
1) When performing heavy-duty machining, carefully prevent chips from being
accumulated since hot chips can cause fire.
1-4-6.Noise level
All machineries make sound when operating. With an assistance from noise
dosimeter, the noise level generated when cutting a work piece on ACER mills is
recorded at 76.07 dB(A). This is documented as follows,
Equivalent A-weighted Sound pressure level according to EN ISO 3746: 76.07
dB(A)
Uncertainty, K in decibels: 4.0 dB (A) according to EN ISO 4871
The figure quoted is emission levels and are not necessarily safe working levels.
Whilst there is a correlation between the emission and exposure levels, this cannot

- 15 -
be used reliably to determine whether or not further precautions are required.
Factors that influence the actual level of exposure of the workforce include
characteristics of the work room, the other sources of noise, etc. i.e. the number of
machines and other adjacent processes. Also the permissible exposure level can
vary from country to country, this information, however, will enable the user of the
machine to make a better evaluation of the hazard and risk.
1-4-7.To interrupt machine
WARNING
When leaving the machine temporarily after completing a job, please turn off the
power switch on the operation panel and the main circuit breaker.
