How to use

Before installation, ensure the chainsaw is switched off and the spark plug or battery is disconnected to prevent accidental start. Remove the old bar and chain following the chainsaw manufacturer's instructions, then mount the replacement bar and fit the chain, aligning the drive links in the bar groove. Adjust chain tension so it moves freely but has minimal slack, then secure the bar retaining nuts to the recommended torque. Re-check chain tension after a short run-in period and retighten if necessary.

Usage recommendations

Use a correctly sized cutting chain compatible with an 18" bar and maintain proper lubrication by checking the oil reservoir before use. Regularly inspect the bar groove for wear, keep the bar rails clean, and flip the bar periodically to promote even wear. Replace the bar if the rail thickness or groove wear compromises safe chain seating.
