CAUTION: Do not improperly dispose of the packaging. Send the materials to be recycled or
eliminated in accordance with current legislation.
5.0 ANCHORING AND SERVICE START-UP
5.1 ANCHORING INSTRUCTIONS
The machine must first be checked in order to ensure that it has not suffered any damage during
transport. If so, immediately contact the manufacturer.
The machine must be installed on a firm surface that is as level as possible in order to reduce vibrations
during operation and so that it operates according to the parameters established by the manufacturer.
Page 5
A sling should be placed under the vise casting on
the front of the machine (1) and another under the
pivot casting (2) toward the rear of the machine.
The saw head should be locked in the down
position (not shown).
12
The machine is supplied in a properly designed and sized wood crate/pallet, and it is also wrapped in
plastic before it is shipped. Due to the size of the machine, it should be transported on a forklift or by a
crane bridge, using slings. If the machine is left in storage for a long period of time, lubricate
periodically. Do not expose to the elements.
In the above drawing, the machine is bolted to a
pallet before it is lifted or moved with a forklift.
5.2 CONNECTION TO THE ELECTRIC SYSTEM
Ensure that the power supply voltage corresponds to the voltage on the data plate of the machine.
Connect the cable to the electric system, using a plug that is appropriate for the
characteristics of the same, thereby respecting color codes.
After the machine has been connected, make sure that the rotation of the hydraulic motor matches
with the direction indicated by the arrow shown. If the motor rotation is not correct, swap two
of the incoming power wires and check again.
5.3 INSTALLING THE BAND SAW BLADE
In order to install the band saw blade:
Lift the frame guard and remove the blade guide guards.
Loosen the tension adjuster.
Put on the band saw blade, sending it through the interior of the guides.
Re-tighten the tension adjuster to the colored range shown on the gauge: 90-100 bar.
Put on all of the guards.
ATTENTION: When replacing the band saw blade, always use protective gloves.
DANGER: After changing the band saw blade, put on all guards again.
It is absolutely prohibited to work with them removed!!
Page 6
Turn the saw manually and use a brush to lubricate in between the two guides,
using SAE 30 lubricating oil.
ATTENTION: See the next page to help in selecting the correct blade.
NOTE : The Tension Adjuster is a
self-contained hydraulic unit. If it
won't hold pressure or if it won't
adjust properly, it is low or out of oil.
Remove pressure gauge and top off
with hydraulic oil (ISO 32).
If problem persists, inspect the unit
for leaks and remove and repair as
needed.

5.5 CUTTING COOLANT
CAUTION: When it is necessary to empty the liquid coolant tank, please properly dispose of the
old coolant.
ATTENTION: The use of any other kinds of coolants may cause irreparable damage to the machine,
as well as diminish the quality of the cut and reduce the life of the saw.
6.0 INSTRUCTIONS FOR USE
6.1 VISE ADJUSTMENT AND MITER LEVER
Use only pure, synthetic water-soluble sawing coolant in this saw. The saw holds 4 gallons. Coolant
should be mixed in a ratio of one part coolant to seven parts water. Premixing the coolant before
adding to the saw is also recommended. Add through the top of the saw. DO NOT OVER FILL!!
