Maintenance
Before doing maintenance
on the machine, disconnect it from the
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, and the guide bearings,
clean and free of resin.
Keep the 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 the band wheels to
avoid vibration and potential blade breakage.
Vacuum or blow out dust from inside the
cabinet. (Use proper dust mask equipment).
The table surface must be kept clean and free of
rust for best results. If rust appears, you can use
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 the 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.
Lubrication Points:
Periodically apply a light, non-hardening grease
to the rack and pinion system of the guide post
(Figure 49).
Grease the sliding surfaces of the table
trunnions (Figure 50). Also grease the contact
area of the trunnion scale and handwheel gear
(Figure 50) and the other gears connected to the
handwheel (Figure 51).
Grease the blade tension screw (Figure 52).
Oil any pins, shafts, and joints. Do not get oil on
the pulleys or belts.
Note: Bearings on the band saw are sealed for
life and do not require lubrication.
