FAQs
How do I confirm this chain fits my saw?
Check your chainsaw's manual for the required bar length (40cm/16in), chain pitch (3/8 LP), gauge (1.3mm), and the number of drive links (57). This chain is specifically designed for these specifications.
What does '3/8 LP' mean?
'3/8' refers to the chain pitch (distance between drive links), and 'LP' stands for Low Profile, indicating a chain designed for reduced vibration and kickback, often used on smaller saws.
What is the 'gauge' of the chain?
The gauge (1.3mm or 0.050 inches) refers to the thickness of the drive links that fit into the groove of the guide bar. It must match your saw's bar for proper fit.
How often should I sharpen the chain?
Sharpen the chain when you notice a decrease in cutting performance, or when you see sawdust instead of chips. Frequent sharpening, typically every 5-10 minutes of cutting time depending on conditions, is recommended.
Is this chain suitable for professional use?
This chain is generally suited for domestic and occasional use. For heavy-duty, daily professional logging, a more robust professional-grade chain might be necessary.
What are drive links?
Drive links are the bottom parts of the chain that sit in the guide bar groove and engage with the drive sprocket. This chain has 57 of them.
Where can I find the drive link count on my current chain?
You can count them manually by carefully inspecting your existing chain. Alternatively, check your chainsaw's manual or the product description of the original chain.
Troubleshooting
Chain not cutting effectively
The chain may be dull. Sharpen the cutters or replace the chain if significantly worn. Ensure the chain is correctly tensioned and lubricated.
Chain derails from the bar
Check chain tension; it may be too loose. Ensure the chain is correctly seated on the sprocket and in the bar groove. Verify the bar is not bent or damaged.
Chain is difficult to move by hand
The chain tension is likely too high. Loosen the bar adjustment nuts and re-tension the chain to allow free movement while maintaining snugness.
Chain appears to be stretching excessively
This can be normal for new chains (break-in period). Re-tension as needed. For older chains, it may indicate wear and require replacement.

Setup, Compatibility & Care
Compatibility Check: Before installation, verify that your chainsaw requires a 40cm (16in) bar and exactly 57 drive links. Confirm that the chain pitch is 3/8 Low Profile (LP) and the gauge is 1.3mm. Refer to your chainsaw's manual or the specifications of compatible models like Bosch AKE40-19S Pro, AKE40B, AKE400, GKE40BC, GKE40BCEPro 2100CSA, Ryobi RCS-3540C, and B&Q TRY38PCSA 38cc.
Installation: Ensure the chainsaw is turned off and the spark plug is disconnected for safety. Remove the chain cover. Loosen the bar nut and remove the old chain. Place the new chain onto the bar, ensuring the drive links sit correctly in the bar groove. Route the chain around the sprocket. Reinstall the chain cover and tighten the bar nut. Adjust chain tension according to your chainsaw's manual – the chain should be snug but still movable by hand.
Care: Regularly inspect the chain for signs of wear, dullness, or damage. Sharpen the chain cutters with a file of the appropriate size (typically 5/32 inch for 3/8 LP) and angle as needed. Keep the chain properly tensioned; a loose chain can derail, while an overly tight chain causes excessive wear. Clean the chain and bar groove after each use to remove sawdust and debris. Proper lubrication is crucial; ensure your chainsaw's automatic oiler is functioning correctly or manually oil the chain if required.
