Safety of woodworking machines - Circular sawing machines - Part 17: Manual horizontal cutting cross-cut sawing machines with one saw unit (manual radial arm saws)

This document deals with the significant hazards, hazardous situation and events as listed in clause 4, relevant to stationary and displaceable manual horizontal cutting cross-cut circular sawing machines with one saw unit (manual radial arm saws), hereinafter referred to as "machines", designed to cut solid wood, chipboard, fibreboard, plywood and also these materials if they are covered with plastic edging and/or plastic laminates, when they are used as intended and under the conditions foreseen by the manufacturer.
NOTE1  For the definition of stationary and displaceable machine see 3.2.3 and 3.2.4.
This document does not apply to:
a)   machines set up on a bench or a table similar to a bench, which are intended to carry out work in a stationary position, capable of being lifted by one person by hand. The bench can also be an integrated part of the machine if it consists of hinged legs which can be extended down;
b)   machines fitted with hydraulically powered machine actuators (e.g. hydraulic workpiece clamping);
c)   machines fitted with powered work-piece positioning;
d)   machines fitted with the facility for either ripping, milling (including trenching and grooving), sanding and/or drilling;
e)   machines equipped with more than one saw spindle speed.
NOTE 2  A standard to cover machines that can be used for ripping and moulding will be considered at the next revision.
NOTE 3  Semi-automatic and automatic horizontal cutting cross-cut circular sawing machines with one saw unit (radial arm saws) are dealt with in EN 1870-11.
NOTE 4 Transportable electrically driven machines excluded by the scope of this European Standard are covered by the requirements of EN 61029-1:2000 and prEN 61029-2-2:2003.
This document is not applicable to manual horizontal cutting cross-cut circular sawing machines with one saw unit (manual radial arm saws) which are manufactured before the date of its publication as EN.

Overview

EN 1870-17:2007/FprA2 is a CEN draft amendment addressing the safety of woodworking machines, specifically manual horizontal cutting cross‑cut circular sawing machines with one saw unit (manual radial arm saws). The document covers significant hazards, hazardous situations and events for stationary and displaceable manual radial arm saws used to cut solid wood, chipboard, fibreboard and plywood - including panels with plastic edging or laminates - when used as intended and under manufacturer‑specified conditions. The amendment refines requirements related to saw blade mounting, guarding and chip/dust emission to support compliance with the Machinery Directive.

Key topics and technical requirements

• Scope and exclusions
  • Applies to stationary and displaceable manual radial arm saws for cross‑cutting wood and wood‑based panels.
  • Explicitly excludes small bench/table machines liftable by one person, machines with hydraulic actuators, powered workpiece positioning, machines that can rip/mill/sand/drill, machines with multiple saw spindle speeds, and machines manufactured before the publication date.
• Saw blade mounting
  • Amendment clarifies flange sizing and clamping details to reduce risk of blade ejection and kickback:
    • For saw blades ≤ 450 mm, flange diameter ≥ D/4 (D = largest blade diameter machine is designed for).
    • For blades > 450 mm, flange diameter ≥ D/6 but not less than 115 mm.
    • Outside flange clamping surface ≥ 5 mm in width and recessed toward the centre.
• Guarding of the saw blade
  • Access to the cutting area under the fixed guard must be limited by:
    • An adjustable guard enclosing the cutting area that can be manually adjusted down to at least fence level (ideally to the workpiece top) and that allows blade change without removal; or
    • A manually adjustable or self‑adjusting guard for the down‑cutting teeth between the fixed guard and the fence/top of workpiece, covering the periphery and sides as specified.
  • Operator must be able to see the cutting line during operation.
• Chip and dust extraction
  • The amendment includes a note recommending a minimum extraction airflow (document text: recommends an airflow of at least "800 m h", commonly interpreted as an extraction capacity guideline).

Applications and users

• Who uses this standard:
  • Machine designers and manufacturers of manual radial arm saws
  • Safety engineers, conformity assessors and notified bodies working under the EU Machinery Directive
  • Workshop owners, installers and maintenance personnel responsible for machine guarding and dust extraction
• Practical value:
  • Ensures safer blade mounting and guarding designs that reduce kickback and blade ejection risks
  • Defines guarding and extraction practices that protect operators and improve workplace safety and compliance

Related standards

• EN 1870-11 (semi‑automatic/automatic radial arm saws)
• EN 61029-1:2000 and prEN 61029-2-2:2003 (transportable electrically driven machines)
• Machinery Directive (informative annexes referenced in the document)

Keywords: EN 1870-17:2007, manual radial arm saws, woodworking machine safety, circular sawing machines, saw blade mounting, guarding, dust extraction, CEN.
