PEAK Chain Bar Oil ISO 150 20L | Chainsaw Bar & Chain Lubricant

Product Description

PEAK Chain Bar Oil ISO 150 is a specialised, high-viscosity lubricant developed for the effective lubrication of chains, guide bars and sprockets on modern chainsaws and other chain-driven equipment. Formulated with a tackiness agent, this chain bar oil forms a strong lubricating film that adheres to moving metal surfaces and helps resist excessive sling-off during high-speed operation.

Chainsaw chains and guide bars operate under demanding conditions involving rapid movement, friction, heat, shock loading and constant exposure to sawdust, dirt, moisture and other contaminants. Using an ordinary lubricating oil may result in the lubricant being thrown away from the chain before it can provide adequate protection. PEAK Chain Bar Oil is designed specifically for this operating environment, providing reliable adhesion and maintaining a protective oil film across the chain, guide bar and sprocket.

The ISO 150 viscosity grade provides a substantial lubricating film suitable for a broad range of general chainsaw and chain-drive applications. Its combination of viscosity, tackiness and surface adhesion helps reduce direct metal-to-metal contact, supporting smoother operation and helping protect components against premature wear.

Supplied in a practical 20-litre container, PEAK Chain Bar Oil ISO 150 is well suited to arborists, landscapers, farmers, forestry operators, firewood processors, property maintenance contractors, workshops and frequent chainsaw users. The larger pack provides an economical supply for businesses and operators who regularly service or operate chainsaws and chain-driven equipment.

Key Features and Benefits

Strong Adhesion to Chains and Guide Bars

PEAK Chain Bar Oil contains a tackiness agent that improves the lubricant’s ability to remain attached to the chain, guide bar and sprocket. This is particularly important because chainsaw chains travel at high speed and can rapidly throw off lubricants that do not have sufficient adhesive characteristics.

By helping the oil remain on the working surfaces, the formulation supports more consistent lubrication and reduces unnecessary lubricant loss during normal operation.

Wear Protection

The oil forms a protective lubricating film between the chain and guide bar. This film helps reduce friction and direct contact between moving metal surfaces, supporting improved component protection and dependable chainsaw operation.

Effective lubrication can help reduce wear on the chain drive links, guide bar rails, nose sprocket and drive sprocket. It can also support smoother chain movement and help reduce the heat generated by friction.

Rust and Corrosion Protection

Chainsaws and other outdoor equipment are commonly exposed to moisture, damp timber, rain, condensation and changing storage conditions. PEAK Chain Bar Oil provides protection against rust and corrosion, helping preserve lubricated metal components during operation and storage.

This protection is particularly valuable for equipment used seasonally or stored for extended periods between jobs.

Resistance to Sling-Off

The tacky lubricating film is designed to resist being immediately thrown away from the chain as it travels around the guide bar. Reduced sling-off allows more of the lubricant to remain where it is needed and can help decrease unnecessary oil consumption.

Some oil discharge from a functioning chainsaw lubrication system is normal. However, the use of a dedicated chain bar oil provides better adhesion than many ordinary oils that were not designed for high-speed chain applications.

Good Low-Temperature Properties

PEAK Chain Bar Oil has good low-temperature properties, supporting reliable movement through compatible chainsaw oiling systems under a range of operating conditions. This helps the lubricant reach the chain and guide bar through either an automatic or manually operated oil delivery system.

Always check that oil is reaching the chain before commencing extended cutting work, particularly after storage or when operating in cold conditions.

Supports Longer Component Life

Maintaining an adequate lubricating film can help protect chains, guide bars and sprockets from accelerated wear. Correct lubrication may also reduce the frequency of chain adjustment caused by friction-related heat and wear.

Actual component life depends on equipment condition, cutting technique, chain tension, chain sharpness, oil delivery rate, operating environment and maintenance practices.

Recommended Applications

PEAK Chain Bar Oil ISO 150 is specifically recommended for lubricating:

• Chainsaw chains
• Chainsaw guide bars
• Chainsaw drive sprockets
• Chainsaw nose sprockets
• Automatic chainsaw oiling systems
• Manually operated chainsaw oilers
• Lumber carriers
• Agricultural chain-driven equipment
• Lawn equipment incorporating suitable chain drives
• Farm machinery requiring a tacky ISO 150 chain lubricant
• Selected motorcycle chain applications where this lubricant type is appropriate
• Other chain-driven machinery requiring an adhesive lubricating oil

For motorcycle chains or specialised machinery, consult the equipment manufacturer before use. Some modern motorcycle chains, sealed chains and industrial drive systems may require a dedicated lubricant with different performance characteristics.

Chainsaw Lubrication Performance

During chainsaw operation, the chain slides rapidly along the guide bar rails while the drive links pass around the drive sprocket and bar nose. These components are subject to continuous friction, and inadequate lubrication can lead to overheating, increased chain stretch, guide bar damage, accelerated sprocket wear and possible chain seizure.

PEAK Chain Bar Oil is intended to create a persistent lubricating film across these moving surfaces. Its ISO 150 viscosity provides sufficient oil body to help maintain separation between components, while its tackiness supports retention on the moving chain.

The product is suitable for chainsaws equipped with automatic lubrication systems as well as equipment using manually operated oilers. The oil reservoir should be checked regularly and replenished before the level becomes too low to maintain reliable chain lubrication.

Handling & Storage Advice

Store PEAK Chain Bar Oil in its original, correctly labelled container with the cap securely closed. Keep the container in a cool, dry and well-ventilated area away from direct sunlight, excessive heat, ignition sources, strong oxidising materials and unnecessary exposure to moisture or contamination.

Avoid introducing sawdust, dirt, water, fuel, solvents or used lubricant into the container. Contaminated chain oil may restrict the equipment’s oil delivery system or contribute to accelerated component wear.

Use appropriate personal hygiene and avoid prolonged or repeated skin contact. Suitable protective gloves should be worn when filling equipment, cleaning spills or handling oil-contaminated components. Wash hands thoroughly after use and before eating, drinking or smoking.

Clean spills promptly because lubricating oil can make floors and work surfaces extremely slippery. Contain larger spills using a suitable absorbent material and prevent the oil from entering drains, soil, waterways or stormwater systems. Dispose of recovered oil, absorbent material and empty containers in accordance with applicable local and environmental requirements.

Use appropriate lifting and handling techniques when moving the 20-litre container. Keep the container upright and properly secured during transportation and storage.

Consult the current Safety Data Sheet before workplace use for complete health, safety, spill response, first aid and disposal information.

Directions for Use

Before filling the oil reservoir, switch off the chainsaw or other equipment and allow moving components to stop completely. Position the equipment on a stable surface and clean around the reservoir cap to prevent sawdust and other contamination from entering the lubrication system.

Pour PEAK Chain Bar Oil into the designated chain oil reservoir without overfilling. Securely replace the reservoir cap and wipe away any spilled lubricant before restarting the equipment.

Check that the lubrication system is working correctly. For a chainsaw, follow the manufacturer’s procedure for confirming oil delivery to the chain and guide bar. Never operate a chainsaw if the oiling system is blocked, damaged or failing to supply sufficient lubricant.

Monitor the oil level during operation and refill as required. Inspect the chain, guide bar, drive sprocket and oil delivery ports regularly. Clean blocked oil passages and remove compacted sawdust or debris as part of routine maintenance.

This product is intended as a chain and guide bar lubricant. It must not be mixed with petrol or used as a two-stroke engine oil unless expressly approved by the equipment manufacturer.

Equipment Maintenance Considerations

Chain bar oil performs best when used as part of a complete maintenance program. Operators should maintain correct chain tension, keep the chain properly sharpened and regularly inspect the guide bar for rail wear, burrs, uneven wear or blocked lubrication passages.

Excessively tight chains can create unnecessary friction and heat, while loose chains may derail or damage the guide bar. A dull chain can also increase operating pressure and heat even when the lubrication system is functioning correctly.

If oil consumption changes suddenly, inspect the reservoir, pump, filter, delivery holes and guide bar oil channel. Low oil consumption may indicate a blocked lubrication system, while unusually high consumption may indicate leakage, incorrect adjustment or damage.
