Palmgren Operating Manual & Parts List 9683295
SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION
Faulty cut
Worn out bandwheels. Flywheel housing
full of chips
The support and guide flange of the bandwheels
are so worn they cannot maintain the proper align-
ment of the blade causing’ faulty cutting.
The blade rolling and drawing tracks can have be-
come tapered. Replace the bandwheels. Clean
out chips with compressed air.
Streaked cutting surface
Cut advancing too fast Decrease the speed of the cut advance, exerting
less cutting pressure. Adjust the braking device.
Poor quality blade
Worn out blade or with chipped and/or
broken teeth
Wrong tooth pitch
Blade guide block too far from material to
be cut
Move the blade close to material being cut so that
only the blade section used in the cut is free, This
will prevent deflections that would excessively
stress the blade. See OPERATION SET-UP /
Blade guide insert adjustments on page 7.
Insufficient lubricating coolant or wrong
emulsion
Check level of lubricating coolant level
in the tank.
Increase the flow of lubricating coolant, checking
to ensure the hole and the liquid outlet pipe are
not blocked. Check the emulsion percentage.
Noise on guide blocks
Chipped bearings
Replace blade with a superior quality blade.
Replace it with a new blade.
The teeth in the blade being used are probably
large. Use a blade with higher TPI. Replace
blade choosing the proper tooth pitch.
Dirt and/or chips have come between the blade
and guide bearings. Replace the chipped bearings.
MAINTENANCE
Safety precautions should be observed before and during any
maintenance actions are taken.
• Keep saw clean and dry. Sweep off spots where chips have
collected and wipe spots where coolant has splashed
• Lubricate unpainted surfaces with a light application of medium
consistency machine oil to prevent corrosion after cleaning
• Grease the vise lead screw if vise action becomes difficult
• Replace dull blades and blades which are missing teeth. A clean
saw with sharp blade will yield the best cuts
• Internal parts of the band saw have been completely lubricated
at the factory and do not need to be re-lubricated
WARNING:
Make certain the unit is disconnected from the power
source before attempting to service or remove any component. If
power cord is worn, cut or damaged in any way, have it replaced
immediately by a qualified electrician.
