Tilting saw PTO WSK 7A

flexible cutting with two PTO connections



The HMG rocker circular saw of the WSK 7A series is available with a PTO connection or combined with an electric motor and is driven by a V-belt system. Thanks to two different connections, the PTO shaft can be connected either at the rear or on the side, thus ensuring flexibility when cutting firewood. The V-belts protect the drive systems and increase work safety. Thanks to the welded square steel tube frame, it achieves the highest stability. The large rocker enables quick loading of wood from the side and eliminates the need to open the lid, which ensures more effectiveness when cutting. This system is protected by a European patent (EP 3848170). In addition, the rocker is ergonomically and smoothly designed and is easy to operate thanks to integrated tension springs. The height of the rocker handle is adjustable for comfortable operation. A later retrofitting or conversion of structural components is possible at any time (e.g. saw table for rocker saw).

  • More work safety through V-belt drive
  • Large opening of the feeding device (rocker)
  • Three-point suspension for CAT I and II as standard
  • High cutting depth of 28 cm thanks to a large saw blade with a diameter of 70 cm (30 mm hole)
  • Easy transport thanks to large wheels and a robust, extendable transport handle
  • Slidable rocker extension with section holding device
  • Wide rocker with internal galvanized rocker plate
  • Smooth rocker thanks to strong tension springs and shock absorbers
  • Individually adjustable rocker handle
  • Removable chip ejection grid for quick removal of wood and bark residues

Additionally with combined drive with electric motor:

  • Powerful electric motor in a stable cast iron housing with reinforced base
  • Switch-plug combination with reinforced brake electronics, motor protection and phase inverter
  • A robust square steel tube construction ensures maximum stability. The welded frame is torsion-resistant and withstands the large cutting loads better than a sheet metal construction. A high-quality powder coating protects against rust.
  • The cutting protection device can be opened wide for convenient operation. The system protected by a utility model (EU-Patent EP 3848170) also has a very large opening for the wooden support device (rocker), which enables light wood assembly.
  • A circular saw driven by a V-belt has a better cutting performance because the gear ratio used results in a higher saw blade speed. In addition, work safety is increased if the V-belts can slip when blocked. The V-belt shaft is equipped with two self-lubricating industrial ball bearings and has a long bearing, which withstands the loads better than a short shaft. The V-belts are arranged on the outside, so a quick V-belt change can be carried out and the saw shaft does not have to be laboriously dismantled.
  • The PTO drive can be switched off immediately in the event of a fault and the saw blade comes to a standstill within 10 seconds.
  • The rocker is designed ergonomically and smoothly and is easy to operate thanks to integrated tension springs. Galvanized exchangeable sheets protect the support device from wear.
  • The saw blade protection hood can be swiveled backwards in just a few simple steps, thus enabling the saw blade to be changed very quickly without having to laboriously dismantle the circular saw. The tool for changing the saw blade is securely attached to the machine for transport.
  • An extension that can be pulled out up to 50cm is ideal so that the cut wood does not fall on the floor and at the same time serves to determine the desired section length.

* Bestseller

In its 5/2020 issue, the magazine “Heimwerker Praxis” rated an HMG WE 7-8 tilting circular saw as “upper class” and with a grade of 1.4. An excerpt from the assessment: “… a great machine with a very high safety factor that makes making firewood a fun factor. Every euro is well spent here …”
HMG machines are designed and manufactured according to principles valid machine guidelines. each machine a functional check is subjected to prior to delivery.

Boaters are to be audited, so HMG circular saws by the laboratory are checked. A valid type certificate is in any manual of the machine!
