Installation Instructions
Proper installation of the saw chain is critical for safe and effective operation. Always wear appropriate safety gear, including heavy-duty gloves, when handling the saw chain.
Before You Begin
- Ensure your chainsaw is turned off and the spark plug cap is disconnected to prevent accidental starting.
- Consult your Powerhorse 190557 chainsaw's user manual for specific instructions on removing the old chain and installing a new one.
- Verify that the new chain's pitch, gauge, and drive links match the requirements of your chainsaw's guide bar. This chain is 18 inches, 0.325" pitch, 0.050" gauge, with 72 drive links.
Chain Installation Steps (General Guide)
- Remove the Bar Cover: Loosen the bar nuts and remove the side cover from your chainsaw.
- Remove Old Chain (if applicable): Carefully remove the old chain from the guide bar and sprocket.
- Position the New Chain: Place the new UpStart Components chain around the drive sprocket, ensuring the cutting edges are facing the correct direction (usually forward on the top of the bar).
- Fit onto Guide Bar: Guide the chain into the groove of the guide bar.
- Reattach Bar Cover: Place the side cover back on, but do not fully tighten the bar nuts yet.
- Adjust Chain Tension: Adjust the chain tensioning screw until the chain is snug but can still be pulled freely around the guide bar by hand. There should be no slack on the underside of the bar, and the drive links should sit fully in the bar groove.
- Tighten Bar Nuts: While holding the tip of the guide bar up, fully tighten the bar nuts.
- Check Tension Again: Re-check the chain tension. It should be tight enough that the drive links do not come out of the bar groove, but loose enough to be pulled around the bar by hand without excessive force.

Operation Guidelines
This saw chain is a component of your chainsaw. Always operate your chainsaw according to the manufacturer's instructions provided in your chainsaw's user manual.
Before Each Use
- Inspect Chain: Check the chain for any damage, dullness, or missing links. Replace if necessary.
- Check Tension: Ensure the chain tension is correct. A loose chain can derail, and a too-tight chain can cause premature wear and damage.
- Lubrication: Confirm that the chainsaw's automatic oiler is functioning and that there is sufficient bar and chain oil.
Important: Never operate a chainsaw with a dull or damaged chain. This increases the risk of kickback and makes cutting inefficient and dangerous.
Maintenance
Regular maintenance extends the life of your saw chain and ensures safe operation.
Sharpening
The semi-chisel cutters on this chain require regular sharpening to maintain cutting efficiency.
- Use a round file of the correct diameter (typically 5/32" or 4.0mm for 0.325" pitch chains, but confirm with your chainsaw manual).
- File each cutter at the correct angle, typically 25-35 degrees, as specified by your chainsaw or chain manufacturer.
- File from the inside of the cutter towards the outside.
- Maintain consistent length for all cutters.
- Check and file the depth gauges (rakers) as needed to maintain proper cutting depth.

- Store the chain in a dry place to prevent rust. If storing for an extended period, lightly oil the chain.
