SAFETYCONSIDERATIONS
All safety precautions must be observed during installation, operation, or repair work on the V-18 II bandsaw
machine.
Inspect the machine throughly before power hook-up. Pay special attention to the electrical and hydraulic
systems to ensure no damage was caused in shipping.
Power hook-up should be performed by qualified personel.
If not performing properly the machine should be stopped immediately and set-up or repaired by a qualified
person.
Stock must not be loaded while the blade is running and the V-18 II should not be operated unless all guards,
covers and doors are in place and closed.
Long and heavy stock should be supported where it extends off the saw table.
Operator should keep a safe distance from all moving parts especially the blade and operating vises.
Long hair, loose clothing, or gloves, should not be worn while operating the V-18 II.
Area around the machine should be kept clean and tidy.
The V-18 II machine should be used according to its specifications.
The operator must wear eye protection.
No modifications to the machine are allowed without Hyd-Mech’s prior approval. Any approved
modifications shall be performed by trained personnel.
SECTION 1, INSTALLATION

Pg1.2 V18 2001f
LIFTING AND SHIPPING
To lift a V-18 II bandsaw with a forklift, it must have the following.
Minimum capacity of 7500 LB. at 48" from the mast is required as well as 6'
forks.Always lift the saw from the front as shown. The forks must not be
under the electical / hydraulic cabinet. The saw will have 4 x 4 steel stubes
under each leveling foot, these must be removed (save the bolts for
anchoring)before positioningthe saw.
Lifting the V-18 II from the rear of the machine.
To lift the bandsaw with a crane, position the head to 65°. Then insert
2" diameter shafts through the lifting holes in the machine base (circled in
thephoto). Anexperiencedrigger shouldselect therigging basedonthe
4500 LB. weight of the saw.
WARNING: Underno circumstances should
the lifting chains or straps be pushing
against the head.
REMOVING HEAD RESTRAINT
Before start-up remove the head support strut installed for shipping purposes to secure the head to the base.

Pg1.3 V18 2001f
INSTALLATION OF THE CONTROL PANEL
The V18 II comes equipped an articulating contro panel. This panel is normally removed and placed on the
saw table for shipping purposes. The control panel MUST BE REINSATLLED PRIOR TO MACHINE STARTUP.
Take lifting precautions when installing the panel as it weights 150 LB.
To re-install the panel, follow these steps:
1 Remove all of the packing material.
2 Remove the base front cover from the machine to gain access to the interior of the base.
3 Lift the panel and move it into position as shown below.Insert the extra length of hoses and conduit back
into the front of the saw base enclosure.
4 Insert the four studs into their respective holes and fasten the panel using the supplied 3/8-16 unc nuts and
washers.
5 Level the panel and fully tighten the nuts to lock assembly in place.
6 Place excess cord and hose length neatly inside base the enclosure and replace the base front cover.
WARNING! PANEL WEIGHT 150 LB.

Pg1.4 V18 2001f
LEVELLINGTHE V-18
It is important that the V-18 II be levelled and provision is made to secure the saw with concrete anchors to
the floor. Using a machinist's level, level the saw from side to side and from front to back. When any additional
conveyor(s) are being attached to the machine, they must be aligned to the table of the machine properly.
Misalignment could cause problems during shuttle movements and inaccurate cuts.
HYDRAULIC OIL
The V-18 II bandsaw is supplied with Texaco Rando HD46 oil. If it is necessary to change the oil to a different
brand it is good practice to empty the hydraulic tank using a pump. Fill the hydraulic tank approximately 1/3 full with
the new brand of oil and operate the saw through several cycles with maximum cylinder extension. Drain the
hydraulic tank again and then refill to capacity with the new brand.
CUTTING FLUID
As the V-18 II operates with an open reservoir to contain the cutting fluid, no cutting fluid can be shipped with
the saw. There are two main types of cutting fluids available, oil based and synthetic. For oil based fluids the dilution
ratio is 1:10.One part concentrate to ten parts water. For synthetic cutting fluids dilution, if required, should be done
to the specifications as recommended by the manufacturer.
A machinists level being used in both directions,

Pg1.5 V18 2001f
WIRING CONNECTIONS
After the machine is levelled and anchored the necessary power hook-up needs to be performed. In order to
provide safe operation as well as to prevent potential damage to the machine, only qualified personnel should
make the connections.
BEFORESTART-UPTHEFOLLOWING TWO POINTSSHOULDBE CHECKED
1. Signs of damage that may have occurred during
shipping to the electrical cables and the hydraulic hoses.
2. Thehydraulic oillevel is betweenthe upperand lower
levels on the gauge.
As supplied, the machine is set to run on three phase voltage
as indicated on the serial plate and voltage label.
During the initial hook-up, it is very important to check that the
phase order is correct. This is indicated by the hydraulic system
pressuregauge registeringa pressurerise andthe bladerunning in
a counter clockwise direction. If the hydraulics do not register an
immediatepressure rise, SHUT THE HYDRAULICS OFF and
changethe phaseorder.
ATTENTION: Running the hydraulics "backwards" can damage the hydraulic pump!
Power connection to the machine is made to the L1, L2, L3 and ground terminals located inside the control
panel and next to the fuse holders as shown in the photo.
BLADE TENSION CHECK
When the machine is first started, the blade position must be checked. Open the door at the top
of the head and see that the blade has not moved off of the wheel. It should not be overhanging
from the wheel more that 1/4”, if it is, then consult page 3.2. If it has stayed in it’s correct position,
then check that the blade tension switch is in the “+” position and close the door.
EARTH GROUNDING PROCEDURE
1. Customerto provideand installa groundrod approx..60 (15mm)diameter,copper clad
steel, to be driven no less than 8’ (2.5m) into the ground, no more than 10’ (3m) away from control enclosure.
2. Ground rod to be connected to customer’s in plant ground system. This connection shall be made directly at
theground rod.(If applicable).
3. It is desirable that the overall resistance to ground measured at the ground rod does not exceed 3 ohms.
Customer is advised to consult local power company for further information on grounding.
4. Groundrod tobe connectedto groundterminal incontrol enclosureusinginsulated, strandedcopper wire.
The correct wire size is shown below. MachineFLA 5A 10A 20A 30A 40A
Wire SizeAWG 20 18 16 14 12
5. An additional point to check is ensuring continuity of ground within control enclosure. Start with main power
entranceground terminalwhere internalground conductorsshould originateand connectto, DINterminal strip,
control transformer and the lid of control enclosure. Also PLC and Interface units should have their own ground
conductorsconnected to oneof themain groundterminals.
6. Properlyfunctioning ground systemwill;
- providesafety forpersonnel.
- ensurecorrect operation ofelectrical/electronic devices.
- preventdamage toelectrical/electronic apparatus.
- help dissipate lightning strokes.
- divertstray radiofrequency (RF) energyfrom electronic/controlequipment.

Pg 2.1 V18
START-UP
The V-18 II control console has been designed to simplify the operation of the saw so that the operator has
the ability to stop any function at any time, and to be able to control all the functions of the saw remotely.
We can not overstress the importance of familiarizing yourself with the controls of the V-18 II prior to starting
the machine for the first time.
NOTE: WHEN STARTING THE V-18 II FOR THE FIRST TIME MAKE SURE THAT THE PRESSURE IS 650
± 25 PSI (900psi for extended head machines), AND THAT THE BLADE IS RUNNING IN A COUNTERCLOCK-
WISE DIRECTION AS VIEWED FROM THE DOOR SIDE THE OF HEAD.
CONTROL CONSOLE
The operator console has the ability to articulate to suit the preference of the operator. It is arrayed with a
complete set of controls to operate both the hydraulic and electrical functions of the saw. All of the selector
switches have to be placed in their neutral center position for the hydraulics to start. This is a safety feature
which is designed to prevent any un-wanted hydraulic actuation without the concious intervention from the
operator.
