Operation Instructions - Urrea SB1018 Manual De Usuario

• This band saw has two blade speed, low speed
and high speed.
• The lower wheel 'A' has two, integral, multi-
vee form pulleys and the motor shaft has a twin
multi-vee form pulley 'B'.
• The multi-vee belt 'C' passes around the wheel
pulley and the motor pulley. The belt tension is
released and applied by using the cranked han-
dle 'D'.
• For the high speed, the belt should be fitted to
the rear pulley on both the motor and wheel.
• For the low speed, the belt should be fitted to
the front pulley on both the motor and wheel.

OPERATION INSTRUCTIONS

SAFETY PRECAUTIONS BEFORE OPERATION
The operation of power tools involves a certain
amount of hazard for the operator. Before at-
tempting regular work we recommend you get
the feel of operations using scrap lumber to check
settings. Read entire instructions before you start
to cut work piece. Always pay attention to safety
precautions to avoid personal injury.
Band saw includes ripping and crosscutting, plus
a few other standard operations of a fundamen-
tal nature. The following methods feature safety.
As with all power tools there is a certain amount
of hazard involved with the operation and use of
tool.
Using the tool with the respect and caution de-
manded as far as safety precautions are over-
looked or completely ignored, personal injury to
the operator can develop. It is good practice to
make trial cuts using scrap material when setting
up your operations.
CROSSCUTTING
Crosscutting is the process of cutting across the
grain of wood, for plywood and other processed
wood, crosscutting simply means cutting across the
width of material.
1. Mark the work piece on the edge where you
want to begin the cut.
2. Adjust the blade guide assembly to the correct
height and make sure the miter gauge is set to 90°.
3. Move the fence out of the way, place the work
piece evenly against the miter gauge.
4. Hold the workpiece against the miter gauge
and line up the mark with the blade.
5. After all safety precautions have been met, turn
the band saw on, slowly feed the workpiece into
the blade and continue the cut till the blade is all
the way through the workpiece.
The picture shows a 90° crosscutting operation.
RIPPING
Ripping is the process of cutting with the grain of
the wood stock, for plywood and other processed
E N G L I S H •
wood, ripping simply means cutting down the
length of the workpiece.
1. Adjust the fence to match the width of the cut
on your workpiece and lock the fence in place.
2. Adjust the blade guide assembly to the correct
height.
3. After all safety precautions have been met, turn
the band saw on, slowly feed the workpiece into
the blade is completely through the workpiece.
The picture shows a typical ripping operation.
NOTE: If you are cutting narrow pieces, use a push
stick to protect your fingers.
RESAWING
Resawing is the process of cutting a board
into two or more thinner boards, the maxi-
mum board width that can be resawn is
limited by the maximum cutting height of the
band saw.
One of the most important considerations when
resawing is blade selection, generally, the wider
blade, the better. In most applications, a hook or
a skip tooth style will be desirable. Choose blades
with fewer teeth per inch (from3 to 6), because
they offer large gullet capacities for clearing saw-
dust, reducing heat buildup and reducing strain on
the motor.
CUTTING CURVES
When cutting curves,
and turn the stock carefully so that the
blade follows the layout line without twis-
ting, if a curve is so abrupt that it is necessary to
repeatedly back up and cut a new kerf, use either
a narrower blade or a blade with more TPI (teeth
per inch), or make more relief cuts.
Always make short cuts first, then proceed to the
longer cuts, relief cuts will also reduce the chance
that the blade will be pinched or twisted. Relief
cuts are cuts made through the waste portion of
the workpiece and are stopped at the layout line.
As you cut along the layout line, waste wood is
released from the workpiece, alleviating any pres-
sure on the back of the blade, relief cuts also make
backing the workpiece out easier, if needed.
STACKED CUTS
One of the benefits of a band saw is its ability to
cut multiple copies of a particular shape by stack-
ing a number of workpieces together.
Before making stacked cuts, ensure that both the
table and the blade are properly adjusted to
90°, otherwise, any error will be compounded.
This band saw requires very little maintenance
other than minor lubrication and cleaning. The fol-
lowing sections detail what will need to be done in
order to assure continued operation of your saw.
