Comprehensive Guide to Chainsaws in Australia: Petrol, Electric, and the BAUMR-AG 52cc SX52 Compared

Testing statement: Firebusters has not personally tested these chainsaws. This comparison is based on current BAUMR-AG/Edisons specifications and manufacturer documentation. Product specifications, availability and inclusions can change, so check the current listing and manual before purchase or use.

BAUMR-AG Chainsaws Compared

This guide compares three different BAUMR-AG chainsaws for Australian homeowners and property owners:

• SX52 – 52cc petrol, 20-inch bar
• SX62 – 62cc petrol, 20-inch bar
• SC5 – 2000W corded electric, 16-inch Oregon bar and chain

The important point is that engine size or wattage alone does not determine which chainsaw is appropriate.

Consider bar and chain specifications, machine weight, fuel or power requirements, maintenance, operator experience and the actual cutting task.

25:1 Fuel Mix

The current SX52 specification requires a 25:1 petrol-to-two-stroke-oil mixture.

That means the fuel mixture and the chain/bar lubricant are two separate things.

The supplier specifies:

• 95+ RON regular unleaded petrol
• 25:1 petrol/oil ratio for the engine
• separate chain/bar oil reservoir

Follow the current manual rather than assuming the same mix used by a different two-stroke machine.

20-Inch Bar Does Not Mean a 500mm Cutting Capacity

The bar is marketed as 20 inches, but the supplier publishes a 430mm maximum cutting length.

That published figure is more useful when assessing practical clearance than simply converting 20 inches into millimetres.

SX52 Chain Specification

Replacement chains need to match all three important measurements:

• .325-inch pitch
• .058-inch gauge
• 76 drive links

Do not select a replacement chain using bar length alone.

Integrated Chain Brake

The SX52 has an integrated chain brake.

The BAUMR-AG manual states that the brake is intended to stop the chain rotating even while the engine is running and should be engaged:

• in an emergency
• before starting the engine
• while the engine is idling where directed
• during transport
• during storage

A chain brake reduces risk but does not eliminate chainsaw kickback.

BAUMR-AG SX62 62cc Petrol Chainsaw

SX62 Key Specifications

• 62cc two-stroke petrol engine
• 3HP / 2.2kW supplier-rated maximum output
• 20-inch sprocket-nose bar
• .325-inch chain pitch
• .058-inch chain gauge
• 76 drive links
• 550mL fuel tank
• 25:1 fuel/oil ratio
• 95+ RON petrol
• integrated chain brake
• E-Start recoil system
• anti-vibration system
• approximately 7kg product weight
• approximately 90 × 26 × 24cm

Despite the larger engine displacement, the SX62 should not automatically be described as the better chainsaw. It weighs about 600g more than the SX52 and suitability still depends on the cutting task and operator.

BAUMR-AG SC5 2000W Electric Chainsaw

SC5 Key Specifications

• 2000W rated motor
• 220–240V mains supply
• 16-inch Oregon bar and chain
• 14.5m/s published chain speed
• 8000rpm no-load speed
• 3/8-inch chain pitch
• .050-inch gauge
• 56 drive links
• automatic chain lubrication
• tool-less chain tension wheel
• torsion-spring brake
• approximately 5kg product weight

Petrol vs Electric Chainsaw

Petrol

A petrol chainsaw offers independence from an extension lead and power outlet.

That can suit larger properties and work away from buildings.

The trade-offs include:

• fuel mixing
• engine servicing
• spark plug and air-filter maintenance
• hot exhaust components
• fuel storage
• greater fire considerations

Corded Electric

A corded electric chainsaw eliminates fuel mixing and exhaust emissions at the machine.

However, the electrical lead changes the risk profile.

Users need to keep the lead clear of the cutting area and follow electrical-safety requirements for outdoor power equipment.

Do Not Choose by Engine Capacity Alone

A 62cc engine is not automatically more suitable than a 52cc engine.

The SX52 and SX62 both use a 20-inch bar and have the same published chain pitch, gauge and drive-link count.

Factors such as:

• machine weight
• operator experience
• timber size
• timber condition
• access and footing
• duration of work

may be just as important as engine displacement.

Chainsaw Kickback

The BAUMR-AG manual specifically warns operators not to allow the upper tip of the guide bar — the kickback zone — to contact timber or another object.

The manual also says:

• always hold the saw firmly using both front and rear handles
• do not operate above shoulder height
• do not operate where the whole saw cannot be seen
• cut one piece of timber at a time
• remain alert to timber that may pinch the chain

Tree Felling Is Different from Cutting Firewood

Owning a 20-inch chainsaw does not mean a user has the skills required to fell a standing tree.

The BAUMR-AG manual states that tree felling should be performed by trained and experienced personnel.

Large branches, storm-damaged trees, hung-up limbs and timber under tension can move unexpectedly when cut.

If there is uncertainty about the direction of movement, structural condition or safe cutting method, professional assistance is appropriate.

Protective Equipment

The BAUMR-AG manual recommends appropriate protection including:

• eye protection
• hearing protection
• hard hat where relevant
• protective gloves
• heavy-duty safety boots
• close-fitting work clothing
• cut-resistant leg protection such as suitable chainsaw chaps

PPE does not replace training and correct operating technique.

Do Not Use Petrol Chainsaws Indoors

Petrol-engine exhaust contains carbon monoxide.

The manufacturer’s manual warns that combustion engines should be operated outside and away from windows, doors and vents.

Fire Danger Periods and Total Fire Ban Days

Chainsaws can create heat or sparks and petrol chainsaws contain fuel and a hot exhaust.

In Victoria, CFA advises avoiding chainsaw use on Total Fire Ban days wherever possible.

If essential work is carried out in dry vegetation on a Total Fire Ban day, CFA specifies conditions including:

• equipment must be free of defects capable of starting a fire
• an efficient spark arrester must be fitted
• at least three metres around the machine must be clear of flammable material
• a person must remain in attendance
• required water-based fire-suppression equipment must be immediately available

Restrictions vary by state and fire authority, so check the rules applying to your location and day before starting work.

Maintenance Checklist

• Check chain tension before and during use.
• Inspect cutters and drive links for damage.
• Keep the chain sharp.
• Check chain-brake operation.
• Maintain correct chain lubrication.
• Check the guide bar for wear or damage.
• For petrol models, inspect the air filter and spark plug as directed.
• Check for fuel leaks before starting.
• Allow petrol engines to cool before refuelling.
• Use the bar cover during transport and storage.

Important Note About “Commercial” Marketing

The retailer includes the word “Commercial” in the SX52 and SX62 product names.

However, the current BAUMR-AG chainsaw manual also states that the equipment covered by that manual is designed for domestic use only.

For that reason, Firebusters does not interpret the word “Commercial” in the product title as proof of continuous professional-duty suitability.

Anyone intending workplace, contractor or intensive commercial use should confirm the applicable warranty, duty expectations and workplace requirements directly with the supplier.

What About the Supplier’s AS/NZS Claim?

Edisons states that the SX52 and SX62 exceed relevant AS/NZS safety standards.

Firebusters has not independently verified the underlying certification documentation or the precise standard numbers from the information currently published.

Therefore this guide reports it as a supplier claim, not an independent certification finding.

Frequently Asked Questions

How heavy is the BAUMR-AG SX52?

The current published product weight is approximately 6.4kg.

What chain fits the SX52?

The published specification is .325-inch pitch, .058-inch gauge and 76 drive links.

What fuel mix does the SX52 use?

The current specification states 25:1 petrol to two-stroke oil, using 95+ RON unleaded petrol.

Does the SX52 have a chain brake?

Yes. The current specification lists an integrated chain brake.

What is the SX52 maximum cutting length?

The supplier publishes a maximum cutting length of approximately 430mm.

Is the SX52 lighter than the SX62?

Yes. The SX52 is listed at about 6.4kg compared with approximately 7kg for the SX62.

Is the 62cc model automatically better?

No. It has a larger-displacement engine, but both petrol models use a 20-inch bar and the same published chain specification. Weight, experience and actual cutting requirements matter as well.

Which one avoids fuel mixing?

The SC5 2000W corded electric chainsaw does not use petrol or two-stroke fuel.

Can I use the SX52 to fell trees?

The manufacturer manual states that tree felling should be performed by trained and experienced personnel. Do not infer safe felling ability from bar length or engine size alone.

Final Assessment

The three BAUMR-AG chainsaws cover distinctly different setups.

The SX52 combines a 52cc two-stroke engine, 20-inch bar, 6.4kg published weight and .325-inch chain setup.

The SX62 increases displacement to 62cc and weighs approximately 7kg while retaining the same 20-inch bar and published chain dimensions.

The SC5 electric uses a 2000W motor, 16-inch Oregon bar and 5kg body and removes petrol mixing from normal operation.

Firebusters recommendation: choose on the basis of the work, operator experience, bar and chain requirements, weight and available power source rather than simply buying the largest engine.
