2
Workpiece jams during
thicknessing
• Cutting depth too great
• Reduce cutting depth and machine
the workpiece in several passes
Unsatisfactory surface
finish
• Planing blade blunt/worn
• Planing blade filled with chips
• Uneven feed
• Replace or sharpen blade
• Remove chips
• Feed the workpiece with constant
pressure and at reduced speed
Machined surface too
rough
• Workpiece contains too much
moisture
• Dry workpiece
Machined surface cracked • Workpiece was machined against the
grain
• Too much material planed at one pass
• Machine the workpiece from the
opposite direction
• Machine the workpiece in several
passes
Workpiece speed too low
during thicknessing
• Workpiece was machined against the
grain
• Too much material planed at one pass
• Clean bench top and apply a thin
coating of lubricant wax
• Repair transport rollers
• Set the lever for the thicknessing
setting to the top position
