Altendorf F90 Manual May 2026

| Symptom | Likely Cause (per flowchart) | Fix | |---------|-----------------------------|-----| | Burning marks on rip cut | Fence toe-out >0.2 mm | Reset fence parallelism | | Sliding table hard to move | Gib strip too tight or dirty bearings | Adjust to 0.03 mm play + clean rails | | Blade wobble at speed | Arbor nut loose or bent blade | Torque 55 Nm; if persists, replace blade | | Cross-cut not square | Fence stop cam worn | Replace eccentric cam bushing | | Motor won’t start | Guard microswitch open or thermal overload tripped | Close guard; reset button (left side of electrical box) |

This is the heart of the manual. Altendorf assumes the operator has a dial indicator (0.01 mm) and a precision square (grade 00). altendorf f90 manual

The manual provides a mathematical formula to calculate the shim thickness needed for the scoring blade. If the scoring blade is too high, it undercuts the main cut, ruining the edge. The F90 manual includes a life-size ruler diagram on page 34 (varies by revision) to measure the scoring step. | Symptom | Likely Cause (per flowchart) |

The manual divides the F90 into six functional groups: This is the heart of the manual

| Group | Components | Key Adjustment per Manual | |-------|------------|---------------------------| | Base | Welded steel frame, vibration-damping feet | Leveling via eccentric foot screws | | Sliding Table | Precision-ground cast iron, recirculating ball bearings | Gib strip tension (0.02–0.05 mm clearance) | | Fixed Table | Phenolic resin or aluminum (right of blade) | Co-planar with sliding table | | Saw Unit | 5.5–7.5 kW motor, arbor, tilting mechanism (0–45°) | Bevel stop calibration (90° & 45°) | | Rip Fence | Heavy-duty extrusion, micro-adjust cam | Parallelism to blade (+/- 0.1 mm / 2 m) | | Cross-cut Fence | Flip-stop system, scale magnifier | Squareness to sliding table (L-shaped reference) |

Critical manual warning: “Never operate without both table inserts (inner and outer ring). The 3 mm gap is engineered for chip clearance – but fingers are thinner.”
