• The former Elektra Beckum “TKHS 315” table-saw family is now supported by Metabo.
• Publicly available documentation consists of:
– Operating/assembly manuals (multi-language)
– Spare-parts list with exploded drawings (often called “Ersatzteilliste”)
• True “service manuals” (full wiring schematics, test procedures, tolerances) are issued only to authorised workshops; you must request them directly from Metabo Service.
• Download the two documents most owners need from Metabo’s official server:
– TKHS 315 E (PDF, 4 MB):

• If your name-plate shows another suffix (C, M, AUS etc.) search “TKHS 315” on https://www.metabo-service.com ➞ Manuals & Spare Parts, or quote the exact machine number when e-mailing service@metabo.de for the confidential service package.
Brand & ownership
• Elektra Beckum was absorbed by Metabo (1999-2006). All technical support, updates and parts numbering were migrated to Metabo’s system.
Document classes
• Operating / assembly manual (“Betriebsanleitung”) – public, includes general safety, setup, routine maintenance, basic electrics (terminal diagram), and CE conformity.
• Spare-parts list – public, high-resolution exploded views, official part numbers; effectively a mechanical service guide.
• Internal service documentation – restricted, contains wiring diagrams (single-phase and three-phase variants), brake PCB test points, motor replacement procedure, alignment tolerances, and factory jigs.
| Model variants | Suffix | Motor | Brake | Typical sales region | Notes |
|---|---|---|---|---|---|
| 315 E | 2.8 kW, 1~ 230 V | No | EU | Most common DIY model | |
| 315 P | 3.0 kW, 1~ 230 V | Yes | EU/UK | Electronic motor brake | |
| 315 C | 3.0 kW, 3~ 400 V | No | Pro workshops | Star-delta starter | |
| 315 M | 2.0 kW, 1~ 115 V | No | UK/US | Reduced power | |
| AUS | 2.0 kW, 1~ 240 V | Yes | Australia | Local compliance |
Knowing the suffix and serial number is essential when ordering electrical spares (switchgear, capacitors, brake PCB).
Typical service tasks covered only in the restricted manual
• Capacitor sizing and replacement (start 100 µF / run 30 µF, 450 V, ±5 %).
• Brake PCB adjustment (315 P/AUS): R32 must be set for <10 s stop time @ 2900 r·min⁻¹.
• Arbor alignment: ≤ 0.05 mm TIR, measured 40 mm above table.
• Blade height leadscrew lubrication: graphite-/PTFE dry film, oil prohibited.
• Metabo placed its historical database online in 2021; older scans continue to be added.
• EU safety regulations (EN 62841-3-1:2019) now demand electronic brake ≤10 s for ≥200 mm blades, so newer spare-part kits include upgraded brake boards.
• Digital-twin platforms: some aftermarket suppliers (e.g., Spareka, France) now provide 3-D exploded diagrams directly in the browser.
• Why service manuals are restricted: contain type-examination data and proprietary jig instructions. Release is at Metabo’s discretion, usually after proof of professional liability insurance.
• If the motor only “hums,” >70 % cases are failed start capacitors; operating manual does not describe this, the service manual does.
• Exploded-view PDF still allows 90 % of mechanical repairs; wiring colours are printed in the parts list margin for basic fault-finding.
• Copyright: PDFs on Metabo’s site are free for end-user download; redistribution of the confidential service pack without permission infringes intellectual property.
• Safety: Any modification to brake circuitry voids CE conformity; DIY rewiring must follow EN 60204-1 principles (EMERGENCY-OFF, undervoltage release).
• Even the internal service manual lacks full schematics of third-party motors (ABB, WEG) supplied in some regions.
• Units built pre-1994 may have non-CE starters; Metabo recommends complete switch-box upgrade rather than part repair.
• Investigate retro-fitting riving-knife quick-release systems to TKHS 315 to comply with latest OSHA/EN standards.
• Compare efficiency gains when replacing original 2.8 kW induction motor with IE3 3 kW unit.
• Develop 3-D-printed dust-extraction hood adapters to meet <2 mg/m³ workplace dust limits.
Elektra Beckum TKHS 315 documentation now resides under Metabo. Public PDFs (operating manual + spare-parts list) cover most mechanical and light electrical service needs; direct links are given above. For the full service manual with schematics and adjustment tolerances, supply Metabo Service with your exact model/serial data—access is restricted for safety and copyright reasons. Carry out all repairs following EN 60204-1 and local regulations to maintain conformity and operator safety.

Detailed problem analysis
Brake technologies compared
• Mechanical brake – brake shoes, discs or pawls that physically clamp the shaft. Not installed in TKHS 315 and would require a completely different motor/ arbor design.
• Electronic (DC-injection) brake – when OFF is pressed, a control board feeds low-voltage DC into the stator windings for 1-2 s. The stationary magnetic field produces a counter-torque that stops a 2900 r/min blade in < 10 s, meeting EN 62841-3-1.
Model matrix (factory configuration)
*Rundown time for a 315 mm blade, no load.
Identifying what you have
a. Read the type plate: “…TKHS 315 P” → has brake; “…TKHS 315 E” → no brake.
b. Observe stopping time: < 10 s with audible “buzz” = brake present.
c. Open the switch box only with mains plug removed; a populated PCB behind the switch is the brake module.
Electronic brake circuit (principle)
[ I{DC}\approx\frac{U{mains}}{R_{lim}}\quad\text{applied for }t\approx 1{-}2\text{ s} ]
A TRIAC or solid-state relay switches the DC; a series resistor or phase-angle control limits current. Thermistor or Klixon protects the motor from overheating during the brake pulse.
Current information and trends
• Since 2019 the harmonised standard EN 62841-3-1 obliges < 10 s stop time for blades ≥ 200 mm on new machines marketed in the EU. Metabo (owner of Elektra Beckum brand) therefore delivers only “P” or equivalent brake versions in EU today.
• After-market DC-brake modules (e.g. Bernstein, Klinger-Born) are available for retrofitting older E/C models.
• VFDs with dynamic-braking choppers are emerging for three-phase retrofits but require motor insulation class F or better.
Supporting explanations and details
Example: If a TKHS 315 P is switched off at 2 800 r/min, the brake injects ≈30 V DC, 8 A into the 2 kW stator for 1.2 s. Kinetic energy
[ E_k=\frac{1}{2}J\omega^2\approx 55\;\text{J} ]
is dissipated as I²R heat in stator copper; temperature rise stays < 15 K.
Analogy: The DC field “grabs” the squirrel-cage like a magnetic vise, similar to how an eddy-current brake slows a roller-coaster.
Ethical and legal aspects
• Removing or disabling the brake violates CE conformity and may invalidate insurance.
• Only qualified electricians may service the brake board; capacitor stores energy after unplugging.
• Retrofitting must follow the Low-Voltage Directive and Machinery Directive; issue a new EC Declaration if you resell.
Practical guidelines
Implementation / retrofit steps for an E-model:
Best practices:
• Test the brake weekly: stopwatch ≤ 10 s.
• Replace the 10 µF/400 V polypropylene brake capacitor every 7–10 years.
• Keep cooling slots clean to prevent thermal cut-out trips.
Potential challenges and mitigation:
• “Brake sticks on” → relay contacts welded; replace board.
• “Motor hums, won’t start” → brake not releasing; check DC contactor wiring.
Possible disclaimers or additional notes
– Very early 1990-s Elektra Beckum hobby saws (< 1995) were sold without any brake regardless of suffix; always confirm with type plate.
– Retro-brake installation on C (3-phase) model needs a 230 V control transformer or a VFD-based brake; wiring differs from 1-phase kits.
– Mechanical add-on disc brakes advertised online often lack certification and may overload the arbor bearings.
Suggestions for further research
• Compare energy-dissipation profiles between DC-injection and regenerative braking on small induction motors.
• Investigate permanent-magnet synchronous motor swaps for higher efficiency and integrated dynamic braking.
• Follow IEC 60204-1 Ed.7 draft, which may tighten stop-category requirements for woodworking machines.

Brief summary
No TKHS 315 uses a mechanical friction brake. If your saw has the “P” suffix (or certain export variants), it incorporates an electronic DC-injection motor brake that stops the blade in < 10 s; other versions have no braking device. Always verify via the type plate and observe stopping behaviour, and service or retrofit only with certified components to retain CE compliance and operator safety.
