HUSQVARNA LAUNCH 'LEGENDARY' NEW CHAINSAWS
Led by 572 XP

Husqvarna chose the Forst Messe, forestry machinery exhibition in Lucerne, Switzerland last Thursday (August 17th) to launch their new generation 70cc chainsaws – which the company are describing as legendary.


572 XP

The company say these new chainsaws, led by the 572 XP, are built around six key factors which can generate high power output and rapid acceleration, which they believe make them ‘agile productivity powerhouses’.

The new 572 XP won’t be in seen in UK dealerships until Q1 of 2018, but the global rollout will begin very soon with Austria, Poland and Switzerland taking delivery in October of this year. North America will have to wait until the second half of next year with the Rest Of World following up in 2019.

Pavel Hajman, President of the Husqvarna division, led the presentations last Thursday to the assembled, guests, European dealers, and press saying he had “tremendous pride” in the new chainsaws.

He said, “Since Husqvarna started chainsaw production almost 60 years ago, we have been focused on constantly improving chainsaw performance and the user experience.

“We are confident that the new 572 XP will show that Husqvarna is an innovation leader in the world of chainsaws, with a strong commitment on sustainability.”

Gent Simmons, Global Director Product Management Chainsaws, also spoke, telling the audience, “This saw has developed from us getting out and truly understanding our customers. In every part of the world they all have different needs which we have addressed.

“Also, its incredibly important for us to speak to our dealers worldwide,” he said. “They are such an important knowledge bank for us to drawn upon. We pride ourselves in staying close them – and our customers.”

These new chainsaws are built from scratch on a new platform, which Husqvarna believe is set to be the new foundation for professional chainsaws going forward. Their development has benefitted from digitalisation, as Husqvarna has further employed new technical solutions including sensor-based data collection and digital prototyping. Digital prototyping enables highly accurate stress analysis to optimise chainsaw design, while sensors were placed on the chainsaws in field tests to collect data on usage statistics.

The six key factors that make the 572 XP


12% higher cutting capacity
The 572 XP measures an increased 12% cutting capacity even when using long guide bars compared to older Husqvarna chainsaw models within the 70cc range. This is made possible with the new engine layout and improved cooling..

The engine gives users a 30% broader RPM range compared to previous generations; increasing the optimal range from a band of 2000 to 3000 RPM.

The lighter and smaller diameter of the flywheel generates rapid acceleration.

Power-to-weight

A good power-to-weight ratio means higher productivity due to more available engine output. The power-to-weight improvement comes from better weight distribution in the machine and a good engine layout. The crankshaft and muffler, together with other critical components, have been designed for functionality, and extra reinforcements have been made for enhanced strength and reliability. To balance out this increase, weight optimisation has decreased the weight of several components like the flywheel (30g), starter cover (30g), crankcase (200g), clutch cover (30g), and ignition module (29g).

This translates into a weight of 6.6kg and a power level of 4.3kW, a considerate power-to-weight improvement compared to previous Husqvarna chainsaw models in the same displacement segment.



Cooling capacity up to 20%

Cooler engines equal better power and performance, and increased product lifetime. The 572 XP has an increased cooling capacity of up to 20% compared to previous generations of Husqvarna chainsaws. The boosted cooling capacity is the combination of new hardware, digitalisation, and engine control (soft cut out system).

When it comes to hardware, the heat barrier in the 572 XP is made from specially-crafted polymers which are heat resistant, provide extreme insulation, are light weight and are integrated in the cover..

Digital air flow analysis enables optimisation of airflow in the product, thereby refining the placement of cooling apertures and internal deflectors. The newly designed internals also mean less dust and dirt particles will get trapped in the cooling fins.

The soft cut out system (an ignition management system), protects the engine from harmful over-revving by automatically adjusting the ignition timing at top rpm’s. This means a 30% decrease of internal pressure build up in the engine — compared to Husqvarna chainsaws without this feature — for smoother operation, lower operating temperatures and maximum possible uptime.

Optimized filtration

Standard on the 572 XP is a heavy-duty air filter with a large filtration surface area to enable longer use and better filtration. The larger filtration area — compared to previous generations — means an increase in working intervals with maintained performance and requires less frequent cleaning.

10 times quicker air/fuel mix adjustment

With the launch of the 572 XP AutoTune has been updated, making automatic adjustments up to ten times faster than the previous version. The update has four improvement areas compared to previous generations:

  1. Quicker tuning is made possible by a new micro-processor, which decreases time the system needs to tune the engine. This means in practice, that all the engine settings are 100% correct after the first few cuts.
  2. Broader adjustment range is made possible with new software that calibrates from low speed up to top RPMs.
  3. Partial throttle calibration has been added to AutoTune. Mid-range RPMs are continuously measured by the system and used for optimizing engine performance.
  4. Lean out protection minimizes the risk that overheating will occur, thereby preventing severe engine damage.

New X-CUT chain with start/stop tie-strap
The second chain to leave the new chain factory in Huskvarna, Sweden, is the X-CUT C85, and will be standard on the 572XP from 2018, thereby optimising the cutting experience. The new chain is a full chisel, 3/8” chain for professional use and features a golden tie-strap that helps loggers keep track of the start/finish of their filing loop. The company say the chain is sharp out of the box, pre-stretched, highly durable, and improves cutting efficiency.
