Dustless Petrol Saws

We sell, service and repair dustless petrol power cutters from Husqvarna and Guarda.
The Guarda "Edge" cuts with water and controls dust, slurry and engine exhaust gas with the power of petrol cutting. This means this saw can be used indoors.
The Husqvarna K770Vac is for dry cutting only. As only the dust is collected, it can still not be used indoors because of the exhaust gases.
Both need to be connected to an industrial vacuum.

Husqvarna K 770 VAC

The Husqvarna K 770 VAC is a lightweight power cutter for dry cutting with the benefit of dust extraction.

It has all the features of the standard K770 but with:

  • Easy to connect 2'' hose dust is connected to an external dust extractor.
  • K 770 VAC has an impressive maximum cutting depth of 122 mm with a 300mm blade, (very close to that of a 14''/350mm machine).
  • Suitable with a Husqvarna S26 dust extractor.

Edge Saw with Tri-Vac Technology:
1. Silica dust control via a combination of water delivered
to the blade guard and vacuum suction
2. Helps move harmful fumes such as Carbon Monoxide
away from the operator via vacuum suction and a
hose attachment to the muffler
3. Slurry control via vacuum suction to the blade guard.
• Fumes, dust and slurry are moved down the same hose
and away from the cutting operations
• No electricity & water at the saw
• Quick and easy to set up
• Suitable for general purpose concrete cutting


Cylinder Volume (cm3/cu.in) - 93.6/5.7
Fuel Capacity (Litre/US Pint) - 1.0/2.1
Carburettor type - Walbro
150mm cutting depth

Note: The slurry collection and dust control is still excellent even when not at full depth, or on curved surfaces, especially if the bottom part of blade guard is against the wall. However, when not cutting full depth, a smaller blade does assist slurry collection.

See how to set up your Guarda Edge saw and vacuum here:


For vacuum hoses over 15m in length, and with no on site power, use Edge saw with Slurry Interceptor and Guarda Vacuum generator


For vacuum hoses under 15m in length, and with on site power, use Edge saw with your wet/dry vacuum

For vacuum hoses over 15m in length, and with on site power, use Edge saw with your wet/dry vacuum and a Slurry Interceptor barrel.

Vacuum generator or vacuum must always be placed outside.
Vacuum and water must always be on while the saw is operating or else the hose will melt

Slurry Interceptor
Traps the slurry if your vacuum lines back to the vacuum are too long ie over 15M.
Includes 38mm hose and accessories.
Must be connected to a Guarda Vacuum Generator or a wet/dry vacuum of sufficient capacity
$695 incl GST

Wet/dry vacs:
You require a wet/dry vacuum to connect to the saw. Slurry and water will return to the vac at the rate of 1 litre per minute, so your vac needs to be sufficient capacity and power .
