10.5 Blade Lead
Blade lead, or drift, is when the blade begins to
wander off the cutting line even when the band saw
fence is being used. Figure 42 shows an example of
blade lead. It is more common with small, narrow
blades, and is almost always attributable to poor
blade quality, or lack of proper adjustments. Inspect
the band saw for the following:
•
Fence not parallel to miter slot and blade.
•
Blade not tensioned correctly.
•
Blade is dull.
•
Teeth have excessive "set" on one side of
blade.
•
Workpiece being fed too quickly.
Figure 42
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.
industrial-grade low-friction corrosion-resistant
table coating. While the coating is durable, it can
be damaged if metal or other hard and/or sharp
objects strike, gouge, or scratch the surface.
Significant damage to the coating may affect its
performance. Use care when cleaning and
maintaining the machine.
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).
For model PM1500 only: 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.
For model PM1500 only: 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.
