Operation
Symptom
Possible Cause
Possible Solution
Mortises are
irregular.
1. Chip or feed pressure too great.
2. Chips loading up bit.
1. Use bit with bigger cleanout spirals/reduce feed
pressure.
2. Reduce cutting depth, make more passes, or
sharpen/replace bit.
Machine slows when
operating.
1. Applying too much pressure to workpiece.
2. Too many chips binding the cut.
3. Bit is dull, or bit rotation is incorrect.
1. Feed workpiece slower; use less pressure.
2. Pull workpiece frequently out of bit to clear chips.
3. Replace bit/inspect, reverse chuck rotation.
Holes not drilled
straight into
workpiece.
1. Work table loose.
2. Chuck is not square to the table.
3. Motor is not parallel to the table.
4. Bit is loose in chuck.
5. Bit comes loose or slips during boring
operation.
1. Tighten table lock lever to increase rigidity during
operations; adjust table roller bearings (
Page 33).
2. Inspect and square chuck to table (
Page 33).
3. Adjust motor-table parallelism (
Page 35).
4. Service/clean/tighten chuck (
Page 28).
5. Use bits with
5
⁄
8
" shank/use shorter bit/reduce
cutting depth/avoid plunge cuts.
Mortise and tenons
don't line up well.
1. Table wheels loose in V-ways.
2. Table gib out of adjustment.
1. Clean table wheels/V-ways; adjust wheel eccentric
rods (
Page 29).
2. Adjust gib (
Page 32).
Erratic work table
movement.
1. Wood chips, sawdust and debris caught in
work table handle points.
2. Wood chips, sawdust and debris caught in
work table roller bearing tracks.
3. Wood chips, sawdust and debris caught in
work table leadscrew.
4. Wood chips, sawdust and debris caught in
work table elevation ways.
5. Work table gib too loose/too tight.
1. Clean and lubricate table handle points (
Page 28).
2. Clean and lubricate table roller bearing V-ways and
wheels (
Page 29).
3. Clean and lubricate table leadscrew (
Page 29).
4. Clean and lubricate table elevation ways (
Page 29);
adjust table roller bearings (
Page 33).
5. Adjust gib (
Page 32).
