Maintenance
Before doing maintenance,
disconnect machine from electrical supply by
pulling out the plug or switching off the main
switch! Failure to comply may cause serious
injury.
Clean the band saw regularly to remove any
resinous deposits and sawdust. Keep the miter slot
in the table free of dust and debris. Keep the guide
bearings clean and free of resin.
Grease the rack and pinion system of the guide
bar.
Oil any pins, shafts, and joints. Do not get oil on
the pulleys or belts.
Bearings on the band saw are sealed for life and
do not require lubrication.
Check that the cleaning brush over the lower wheel
is working properly; adjust if necessary.
Remove any deposits from the band wheels to
avoid vibration and blade breakage.
The table surface must be kept clean and free of
rust for best results. If rust appears, use a mixture
of household ammonia, a good commercial
detergent and 000 steel wool. (Alternatively,
commercial rust removers can be found at many
hardware stores.) Then wash table down with hot,
soapy water, rinse and dry thoroughly.
Apply a light coat of paste wax to the table. Or,
some users prefer talcum powder applied with a
blackboard eraser rubbed in vigorously once a
week; this will fill casting pores and form a moisture
barrier. This method provides a table top that is
slick and allows rust rings to be easily wiped from
the surface. Important also is the fact that talcum
powder will not stain wood or mar finishes as wax
pickup can.
If the power cord is worn, cut, or damaged in any
way, have it replaced immediately.
Tire Replacement
1. Disconnect machine from power source.
2. Remove the blade from the machine.
3. Insert a flat head screwdriver beneath the lip of
the tire. Pry up the tire and pull it off the wheel.
If this proves difficult, insert a wood wedge or
dowel into the opening (see Figure 38), and
continue to pry around the perimeter of the
wheel until the tire comes off the wheel.
Figure 38
4. Clean the rim of the band wheel before
installing the new tire.
5. The new tire can be installed without removing
the band wheel from the machine; or, you can
remove the band wheel (see “Band Wheel
Replacement” for removal instructions) and
place it on a workbench, using a home-made
jig to secure it while installing the new tire.
6. Place part of the new tire over the band wheel
and work it onto the rim of the band wheel. If
needed, insert a wood dowel beneath the tire
and move the dowel around the perimeter of
the band wheel to guide the tire on.
NOTE: Although the tire may look too small, it
will stretch around the band wheel with the
proper exertion, and will form a tight fit. Unlike
rubber tires for many older model band saws,
the tires for the 2013 and 2415 will not require
trimming, equalizing, etc., nor do they require
an adhesive. Rather, they are ready to use
immediately after installation.
Band Wheel Replacement
The cast iron band wheels are
heavy; use care when removing them.
Disconnect machine from power, and remove the
blade. Loosen and remove the hex nut and flat
washer at the wheel’s hub. Carefully pull off the
wheel by hand or with a “wheel puller.”
