If the blade is suspect, but replacing it is not
currently an option, the blade lead can be
temporarily compensated for by skewing the fence:
1. Cut a scrap piece of wood about the same
length as the band saw table, and joint one
edge along its length, or rip it on a table saw to
give it a straight edge.
2. Draw a line on the board parallel with the
jointed, or straight edge of the board.
3. Move the band saw fence out of the way, and
carefully make a freehand cut along your
drawn line on the board. Stop about midway
on the board, and shut off the band saw (allow
blade to come to a complete stop) but do not
allow the board to move.
4. Clamp the board to the table.
5. Slide the band saw fence over against the
board until it contacts the straight edge of the
board at some point. Lock the fence down.
6. Use the back adjustment screws (F, Figure 13)
to line up fence against board.
NOTE: Skewing the fence to correct blade lead is
effective for that particular blade; when a new
blade is installed, the fence will need re-adjustment
and re-squaring to miter slot. See appropriate
sections in this manual.
11.0 Maintenance
Before doing maintenance on
the machine, disconnect it from electrical supply by
pulling out plug or switching off main switch!
Failure to comply may cause serious injury.
Clean band saw regularly to remove any resinous
deposits and sawdust.
Keep miter slot, and guide bearings, clean and free
of resin.
Keep blade clean and sharp. Check it periodically
for cracks or other signs of wear.
The drive belt should be checked periodically. If it
looks worn, frayed, glazed or otherwise damaged,
replace it.
Remove any deposits from band wheels to avoid
vibration and potential blade breakage.
Vacuum or blow out dust from inside cabinet. (Use
proper dust mask equipment).
The table surface must be kept clean and free of
rust for best results. If rust appears, it can often be
removed with a mixture of household ammonia,
good commercial detergent and #000 steel wool.
Alternatively, commercial rust removers can be
found at many hardware stores.
Apply a light coat of paste wax to table. There are
also products in aerosol form available in major
hardware stores and supply catalogs. Whatever
method is chosen, the coating should protect the
metal and provide a smooth surface, without
staining workpieces.
If the power cord is worn, cut, or damaged in any
way, have it replaced immediately.
11.1 Lubrication Points
1. Periodically apply a light, non-hardening
grease to rack and pinion system of guide post
(Figure 43).
Figure 43
2. Grease the sliding surfaces of the table
trunnions (Figure 44).
