funcionamento seguro deste equipamento.
TABLE AND BASE
Cleaning the SF.250.C band saw is relatively easy with a
vacuum cleaner to remove excess wood chips and
sawdust, and dust with a dry cloth. If there is any resin,
use a resin remover and a clean cloth to remove it.
Protect unpainted cast iron surfaces by cleaning after
each use, which ensures moisture from wood dust does
not remain in contact with untreated metal surfaces.
Make regular applications of anti-rust or a quality metal
protector.
LUBRICATION
Since all bearings are shielded and permanently
lubricated, just leave them in this way until they need to
be replaced. Do not lubricate them. For the other items
on this machine, an occasional application of electric
machine oil is all you need.
Before applying the lubricant, clean the sawdust. Its
objective is to achieve adequate lubrication. Too much
lubrication will attract dirt and sawdust. Various parts of
your machine can lose their freedom of movement with
excess dirt caused by excessive lubrication.
MAINTENANCE SCHEDULE
Daily:
•Vacuum all the dust from above and around the
machine.
•Clean the table and all unpainted cast iron with a metal
protector
Monthly:
•Check the motor belt tension by checking
damage or wear.
•Clean the accumulation of dust inside and outside
the engine.
BELT ADJUSTMENT AND REPLACEMENT
Your band saw uses a belt that can be adjusted as
follows
1. Disconnect the machine from the power source.
2. Loosen the screws (A) that secure the motor (B) to
the machine as shown in the figure below.
3. Slide the motor position to increase or decrease the
belt tension, so that the belt is tight, with about 1/4
deflection when pressed lightly with your fingers.
4. Tighten the engine adjustment screws again.
When the belt shows signs of wear or breaks, replace it
following the steps described above.
CUTTING TAPE ADJUSTMENT AND REPLACEMENT
The band saw SC.250.C uses a cutting tape that can be
adjusted using the tension regulator handle (A) located
on the top of the equipment. To increase the tension of
the tape, tighten the knob clockwise (when viewed from
above) and if you want to reduce the tension of the tape,
release the knob counterclockwise.

13
When the cutting tape shows any signs of rust, wear or
when it loses its sharpness or even breaks, replace it by
following these steps described above.
CUT QUALITY
The smoothness of any cut depends on a number of
variables. Factors such as the type of material being cut,
type of cutting tape, tool sharpening and cutting rate
contribute to the quality of the cut. Make sure that the
material does not vibrate when cutting.
SUPPORT FOR LONG PARTS
ALWAYS USE A SUPPORT FOR LONG PARTS.
Support long pieces using any convenient shape such
as easels or similar structures to prevent the ends from
falling.
CHECK THE MAKSIWA CATALOG AND FIND
PRODUCTS FOR THIS FUNCTION.
TECHNICAL ASSISTANCE
For your greater safety, entrust repairs, maintenance
and adjustments (including inspection and replacement)
to the technical assistance recommended by MAKSIWA,
which will always use genuine spare parts and
accessories, reassembling your router in the same way
as the original.
