Why Choose a Petrol Chainsaw?

A petrol chainsaw is useful when cutting work takes place away from a convenient electrical supply.

Unlike a corded electric chainsaw, this machine carries its fuel supply with it. That makes the petrol chainsaw format practical for outdoor work where mobility is important.

For Ghanaian users working around farms, properties, construction areas, timber-related operations and other outdoor environments, the ability to operate without a mains power connection can be particularly useful.

However, petrol equipment requires more attention to fuel, engine maintenance, lubrication and starting procedures than many electric alternatives.

Understanding the 58cc Engine

The ART:45020 uses a 58cc, single-cylinder, air-cooled, 2-stroke engine. Its rated power is 2.4kW, approximately 3.2HP.

What Does 58cc Mean?

The 58cc figure refers to the engine’s displacement.

Engine displacement is one of the specifications buyers commonly use when comparing petrol chainsaws. A 58cc engine places this machine in a substantially powered petrol-chainsaw category compared with small consumer saws.

However, engine displacement alone does not determine cutting performance. The chain condition, bar condition, chain tension, wood characteristics, operator technique and engine condition all affect how the machine performs.

What Does 2.4kW Mean?

The stated rated power is 2.4kW, with approximately 3.2HP given as the equivalent figure in the product information.

Power matters because the engine must drive the chain around the guide bar while the chain is cutting through material.

A properly maintained chain and correctly adjusted machine allow the available engine power to be used more effectively.

Understanding the 20-Inch / 500mm Guide Bar

One of the most noticeable specifications is the 20-inch or 500mm guide bar.

The guide bar supports and guides the saw chain around the cutting assembly.

A 20-inch bar provides a substantial cutting setup, making the machine relevant to users who need more reach and cutting capacity than a compact chainsaw typically provides.

It does not mean that every piece of timber should be cut at the maximum possible bar capacity. The appropriate cutting method depends on the material, diameter, position and working conditions.

The Saw Chain

The machine uses a high-quality saw chain, with the manual identifying the chain type as 72LP.

The chain is one of the most important working components of a chainsaw.

A sharp, correctly tensioned chain cuts differently from a dull or improperly adjusted chain. The manual specifically explains that keeping the cutters sharp is important for smooth and safe operation.

Signs That the Chain Needs Sharpening

According to the manual, sharpening should be considered when:

• Sawdust becomes powder-like.
• Extra force is required to make a cut.
• The cut does not go straight.
• Vibration increases.
• Fuel consumption increases.

These signs are useful because a chainsaw should not simply be operated harder when cutting performance begins to deteriorate.

Built-In Chain-Sharpening System

The product information describes the machine as having a built-in sharpening stone / self-sharpening system.

This feature is part of the product’s specified design.

However, users should still follow the manufacturer’s chain-maintenance instructions. The manual provides conventional cutter-maintenance instructions, including the use of a 3/16-inch (4.76mm) round file for the specified 72LP chain.

The self-sharpening feature should therefore not be treated as a reason to ignore regular inspection and proper chain maintenance.

Chain Tension Is Critical

A chainsaw chain should not simply be installed and forgotten.

The manual states that a new chain will expand in length during initial use. It therefore recommends checking chain tension frequently and readjusting it when necessary.

A loose chain can:

• Derail easily.
• Increase wear on the chain.
• Increase wear on the guide bar.

The manual specifies approximately 12–16N·m tightening torque for the relevant bar nuts during installation and instructs the user to check that the chain rotates smoothly and that its tension is correct.

Chain Brake and Kickback Protection

Chainsaws require careful handling because kickback can occur during cutting.

The ART:45020 is equipped with a chain brake, and the product information also identifies a double safety guard.

The manual explains that kickback can occur when the nose or tip of the guide bar contacts an object or when wood closes around and pinches the chain during a cut. The resulting reaction can move the guide bar rapidly upward and backward toward the operator.

How the Chain Brake Works

The chain brake is designed to stop chain rotation when kickback occurs.

The manual explains that the brake can operate automatically through inertial force acting on the weight inside the front guard. It can also be activated manually by pushing the front guard down toward the guide bar.

The brake should be checked before use.

If the chain brake does not function properly, the manual instructs the operator to stop using the machine and have it inspected or repaired.

Safety Should Come Before Cutting

A petrol chainsaw is a powerful cutting machine, so appropriate protective equipment and operating practices are essential.

The warning labels on the machine instruct the operator to:

• Read the owner’s manual before operating.
• Wear head, eye and ear protection.
• Use the chainsaw with two hands.
• Pay attention to kickback danger.

The manual also states that the machine should not be operated when the user’s judgment or ability to operate it safely is impaired.

Use Both Hands

The manual specifies:

• Right hand on the rear handle.
• Left hand on the front handle.
• Thumbs and fingers wrapped around the handles.

This is not a machine intended to be casually operated with one hand.

Do Not Cut Above Shoulder Height

The manual specifically instructs operators not to cut above shoulder height and not to overreach.

Maintaining a stable posture and keeping the cutting area under control are important parts of safe chainsaw operation.

Fuel Requirements

The ART:45020 uses a 2-stroke engine, so fuel preparation is different from that of a conventional 4-stroke petrol engine.

The manual specifies regular gasoline, leaded or unleaded and alcohol-free, mixed with quality-proven motor oil intended for air-cooled 2-cycle engines.

The stated mixture ratios are:

Operating condition	Gasoline : Oil
Up to 20 hours of use	20:1
After 20 hours of use	25:1

The manual also warns against mixing 4-cycle engine oil with the fuel.

Fuel Storage and Handling

Fuel should be handled responsibly.

The manual instructs users to keep open flames away from areas where fuel is handled or stored and to mix and store fuel only in an approved gasoline container.

These requirements are particularly important for workshops, farms, contractors and commercial users who may store fuel for repeated chainsaw operations.

Chain Oil

The chainsaw also requires chain lubrication.

The manual specifies:

• SAE #10W-30 all year round, or
• SAE #30–#40 in summer, and
• SAE #20 in winter.

The machine has a 260ml oil capacity.

The manual specifically warns against using wasted or regenerated oil because it can damage the oil pump.

Proper lubrication is therefore part of routine chainsaw care, not an optional extra.

Where Can a 20-Inch Petrol Chainsaw Be Used?

The product is relevant to a range of outdoor cutting activities where a petrol chainsaw is appropriate.

Agriculture

Farm operators may require a chainsaw for suitable wood-cutting and property-maintenance tasks.

It can be useful where work takes place away from convenient electrical outlets.

Property Maintenance

Large properties may require equipment for clearing suitable vegetation, cutting wood and maintaining outdoor areas.

The 20-inch guide bar gives the machine a substantial cutting setup for such work.

Construction and Site Work

Contractors may require petrol-powered cutting equipment for appropriate timber-related tasks on construction or development sites.

The chainsaw should only be used for materials and cutting situations for which a chainsaw is appropriate.

Timber and Woodworking

Users involved in wood processing can use a petrol chainsaw for suitable initial cutting and preparation work.

The 58cc engine and 20-inch bar provide a substantial combination for users who require more than a small household chainsaw.

Ghanaian Operating Conditions

Chainsaw users in Ghana may work in environments where dust, sawdust, heat, outdoor exposure and extended operating periods are common.

That makes routine maintenance particularly important.

The manual provides dedicated maintenance instructions for the:

• Air cleaner
• Fuel filter
• Oil filter
• Guide bar
• Saw chain
• Clutch components
• Dampers
• Needle bearing
• Other service components

Regular maintenance helps operators identify wear before it becomes a larger equipment problem.

Air-Cooled Engine Maintenance

The ART:45020 uses an air-cooled engine.

The engine relies on appropriate airflow and maintenance rather than a liquid cooling system.

Users should therefore follow the manual’s maintenance schedule and keep relevant areas clean, particularly when working around sawdust and other debris.

The manual also provides a specific anti-freeze operating mechanism for conditions around 0–5°C with high humidity.

Although those conditions may not represent normal operating conditions for most users in Ghana, the mechanism is part of the machine’s documented design and should be operated according to the manual if such conditions are encountered.

Transportation

Moving a chainsaw incorrectly can create unnecessary risk.

The manual instructs users to:

• Stop the engine before carrying the machine.
• Keep the guide bar covered with its protector.
• Keep the muffler away from the body.

The supplied package includes a bar protector, which is part of the standard saw-unit package.

The bar protector should be used during transportation and appropriate storage.

What Comes With the Chainsaw?

The manual identifies the standard saw-unit package as including:

• Power unit
• Bar protector
• Guide bar
• Saw chain
• Plug wrench
• Carburetor-adjustment screwdriver
• Spike and mounting screws

The product information also lists a fuel/oil mixing bottle or container shown in the product photos and a user manual.

Customers should check the actual package at purchase if they need to confirm the physical contents supplied with a particular unit.

Maintenance of the Saw Chain

A chainsaw’s performance depends heavily on its cutting chain.

The manual advises wearing safety gloves and ensuring that the engine is stopped before filing the cutters. The chain should be held securely, and the correct file size should be used.

The manual also instructs users to check the depth gauges and ensure that cutters maintain consistent lengths and appropriate edge angles.

This matters because inconsistent sharpening can affect the quality and behaviour of the cut.

Guide Bar Maintenance

The guide bar also requires inspection.

The manual recommends occasionally reversing the bar to help prevent uneven wear. It also instructs users to check the guide-bar rail for wear and replace or correct the bar when necessary.

This is particularly relevant to users who operate the machine frequently.

A chain and bar should be considered a working system rather than treating the chain as the only component requiring maintenance.

Common Chainsaw Buying Mistakes

Choosing Only by Engine Size

A larger cc number does not automatically make one chainsaw appropriate for every user.

Consider the complete specification: engine, bar length, chain, weight, fuel system, maintenance requirements and intended work.

Ignoring Bar Length

The ART:45020 has a 20-inch/500mm guide bar.

Customers should consider whether this size is appropriate for the type of cutting they actually perform.

Ignoring Chain Condition

A powerful engine cannot compensate indefinitely for a dull or improperly maintained chain.

Forgetting Chain Oil

Chain lubrication is an essential part of operation.

Using Incorrect Fuel Mixture

Because this is a 2-stroke engine, the specified gasoline-to-oil mixture must be followed.

Neglecting the Chain Brake

The chain brake should be checked before operation.

If it does not work properly, the manual says to stop using the machine and have it inspected or repaired.

Petrol Chainsaw vs Cordless Chainsaw

A petrol chainsaw and cordless chainsaw serve overlapping markets but have different operating characteristics.

A petrol chainsaw can be useful where:

• Extended outdoor operation is required.
• Electrical access is limited.
• A fuel-powered machine is preferred.
• The user needs a substantial 20-inch cutting setup.

A cordless chainsaw may be preferable where lower operating noise, simpler starting and battery-powered operation are more important.

The right choice depends on the job, operating environment and user’s priorities.

Petrol Chainsaw vs Electric Chainsaw

Corded electric chainsaws can be convenient around properties where electrical power is readily available.

A petrol machine becomes more practical when cutting locations are spread out or far from electrical outlets.

The trade-off is that petrol equipment requires fuel mixing, engine maintenance, lubrication and additional operating precautions.

For buyers looking specifically for a petrol chainsaw machine in Ghana, these differences should be considered before purchasing.
