The saw blade quickly loses its edge • Dirty logs
• The saw blade is worn out
• Avoid dragging the logs over the ground.
• Debark the log at the point where the saw blade
is to cut
• Saw square blocks off the logs before sawing
boards to reduce the number of cuts made
through bark.
• Replace the saw blade
Crooked kerf • Blunt saw blade
• Feed rate too fast
• Feed rate too slow
• Sawing into partially frozen log
• Regrind the saw blade
• Reduce the feed rate
• Increase the feed rate
• Leave the log to thaw or become completely
frozen before sawing. TIP: Do not approach the
log tentatively; allow the blade to make contact
with the end of the log directly at an adapted
cutting speed.
The saw blade works downwards or upwards
while you saw
• Inadequate saw blade tensioning
• Feed rate too fast
• Saw blade damaged
• Saw blade not tracking properly over the
band wheels
• Increase the saw blade tension
• Reduce the feed rate
• Replace the saw blade
• Fit the saw blade correctly and adjust
the tracking
Bandsaw blade breakage • The saw blade is worn out
• Saw blade blunt and/or fitted incorrectly
• Saw blade over-tensioned
• The blade guide rollers have not been fitted to
match the band wheels
• Worn shoes on the band wheels resulting in the
bandsaw blade coming into direct contact with the
metal
• Replace the saw blade
• Regrind the saw blade
• Reduce the saw blade tension
• Adjust the blade guides

Uneven thickness of sawn wood • The saw bed is springy due to insufficient support • Support the rail and log bed as instructed
The saw blade does not track and backs
out of the band wheels
• Incorrect band wheel adjustment
• Worn band wheel linings

motor is running in the right direction, action:
Reverse the electric motor.
The saw blade is under tension even though
the blade tension has been released using
the T-handle
• The blade tensioning mechanism is seized • Push the T-handle inwards
The saw head is hard to move up and down • The vertical guides are too narrow
• The drum of the saw head’s lifting winch needs
lubricating
• Lubricate with silicone, and loosen the guides
slightly where appropriate
• Lubricate with Superflo
The saw head rattles when it is lowered • The rail component is not flat and breaks
in the saw carriage
• Weigh down the rail component as instructed
so that it is flat
The saw blade overheats when sawing • There is no more water in the water tank
• The water valve is closed
