K 770 SmartGuard

Operational safety

When cutting hard materials in confimed spaces e.g. pipe cutting.

Easy to inspect

Enables easy and visual inspection of the condition of the SmartGuard to secure functionality.

Purposeful design

Guides you to start cutting in the correct zone thanks to the design.

Easy and optimal belt tensioning

The semi-automatic SmartTension minimises the risk of under- and over tensioning.

Light and powerful

A light, compact and powerful machine with superior power-to-weight ratio.

Heavy-duty cutting arm

The new-designed cast magnesium crankcase has a three-bolt joint to attach the cutting head, enabling higher torsional rigidity than the previous two-bolt solution.

Long service intervals

A strong Poly-V belt combined with our maintenance-free starter DuraStarter™ and efficient filter-system Active Air Filtration™ ensures long service intervals.

Digital ignition with optimised timing

Provides a powerful spark with optimized timing, enabling easy start and efficient combustion.

Exceptionally low vibrations

Vibrations below 2.5 m/s2 in the cutter handles for more comfort and longer operation periods.

Easy to start

The unique design of the carburettor, cylinder and digital ignition system, together with air purge and decompression valve ensure an easy start.

Maintenance-free air filter

The only time the filter needs to be checked and changed is if you experience lack of power.

High power with less fuel

Our built-in automatic filter compensation SmartCarb™ maintains high power and lowers fuel consumption.

Optimised engine performance

Optimised engine performance through efficient cylinder design, digital ignition system and X-Torq engine technology.

Less slurry and low water consumption

Excellent dust control with our wet cutting kit. A progressive water valve for exact adjustment of the water volume to efficiently bind the dust and reduce slurry.

Easy to change blade guard position

The light magnesium blade guard facilitates cutting, thanks to its step-less adjustment.

Fits multiple blade bushings

Blades with 20mm and 25.4mm bore can be fitted thanks to the reversible blade bushing.

Efficient power performance

Our X-Torq® engines deliver great power and torque thanks to highly efficient combustion.

Smooth blade stop

Reduces the stop time of the blade when the machine is switched off, which enables you to quickly move on to the next job.

Maintenance-free starter

Our dust-sealed starter, where the return spring and the pulley bearing are sealed, gives a virtually maintenance free starter. Developed with a durable starter cord.

Reduced wear

Reduced wear thanks to the drive belt with fully sealed transmission, which keeps out the cutting dust.

Active Air Filtration™

Our two-step filtration system with centrifugal cleaning and a single paper filter increases product life and extends service intervals.

Anti-vibration system

Reduced vibrations in the cutter handle for more comfort and longer operation periods.

DuraStarter™

Our virtually maintenance free starter, thanks to the dust-sealed starter and the durable starter cord.

Poly-V belt

Provides better transmission of power, less frequent re-tensioning and extended service intervals.

SmartCarb™

Our built-in automatic filter compensation maintains high power during the air filter life time.

Asphalt

Asphalt cutting in roadworks.

Blocks, curbstones and pavers

Cutting building blocks, curbstones and garden pavers.

Burying of cables

Burying of all kinds of cables.

Cast concrete

Cutting cast concrete.

Floors and walls

Regular cutting in floors and walls.
