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, which is a prerequisite for ensuring high power output.
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 wider working range means that the engine, in a predictable way, delivers good power in all working situations and a better response time when revving up or down, making limbing faster.
The lighter and smaller diameter of the flywheel generates rapid acceleration. Combined with good torque, this is the most powerful 70cc chainsaw Husqvarna has ever made.
A good power-to-weight ratio means higher productivity thanks to more available engine output. The power-to-weight improvement in the 572 XP 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. Low carburettor temperatures are fundamental for good starting ability as fuel today starts to evaporate at very low temperatures.
Digital air flow analysis enables optimisation of airflow in the product, thereby refining the placement of cooling apertures and internal deflectors in the 572 XP. 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 (revolutions per minute). 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.
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. Improved filtration capacity and a well-sealed system helps stop abrasive particles entering the combustion chamber for a chainsaw with a healthier engine that can operate for longer.
10 times quicker air/fuel mix adjustment
In 2009, Husqvarna introduced AutoTune, enabling system calibration without the need for manual adjustments. This means the machine will always be correctly tuned in ever-changing operating conditions, which maximises uptime as users need not worry about carburettor adjustments. AutoTune also significantly reduces exhaust emissions, assisting in long term compliance with worldwide emissions regulations# and a cleaner working environment.
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:
- 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.
- Broader adjustment range is made possible with new software that calibrates from low speed up to top RPMs.
- Partial throttle calibration has been added to AutoTune. Mid-range RPMs are continuously measured by the system and used for optimizing engine performance.
- 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 is easy to spot due to the golden tie-strap that helps loggers keep track of the start/finish of their filing loop. Like the other X-CUT chain SP33G, the chain is sharp out of the box, pre-stretched, highly durable, and improves cutting efficiency.
Tested to perfection by the pros
Every part of the 572 XP has been built to meet the toughest conditions around the world, day after day — and field tests conducted by Husqvarna prove the 572 XP chainsaw’s ability to tackle varying altitudes, climates and humidity levels.
