UPFOREST 20 Inch Chainsaw Chain Instruction Manual

Introduction

This manual provides essential information for the safe and effective use, installation, and maintenance of your UPFOREST 20 Inch Chainsaw Chain. Please read these instructions thoroughly before attempting any installation or operation to ensure proper function and user safety. This chain is designed for specific STIHL chainsaw models, as detailed in the specifications section.

Safety Information

Always prioritize safety when working with chainsaws and their components. Failure to follow safety guidelines can result in serious injury.

• Read Chainsaw Manual: Always consult your chainsaw's owner's manual for specific safety instructions and chain replacement procedures.
• Personal Protective Equipment (PPE): Wear appropriate PPE, including safety glasses, hearing protection, gloves, and chainsaw protective legwear (chaps), when handling or operating a chainsaw.
• Chain Condition: Regularly inspect the chain for damage, dullness, or loose components. A damaged or dull chain can increase the risk of kickback and reduce cutting efficiency.
• Proper Tension: Ensure the chain is correctly tensioned before each use. Incorrect tension can lead to the chain derailing or premature wear.
• Low Kickback: This chain is designed to meet low-kickback performance requirements. However, always be aware of kickback risks and operate the chainsaw with both hands firmly.

Product Overview and Features

The UPFOREST 20 Inch Chainsaw Chain is engineered for durability and efficient cutting performance. Key features include:

• Material Quality: Constructed from German steel with controlled heating and punching systems for enhanced toughness and flatness.
• Durability: All saw chain rivets are hardened and quenched to resist wear and improve strength, minimizing chain tension changes.
• Sharpness: Features Japanese chrome-plated technology for cutter durability. Each cutter is ground and cold-headed with rotary machines for optimal sharpness.
• Lubrication System: Integrated oil storage grooves in each drive link and oil storage bumps in each tie strap ensure effective oil distribution throughout the chain. This reduces friction, lowers the tendency for stretching, and extends chain longevity.
• Corrosion Resistance: Each saw chain is pre-treated with protective oil to resist corrosion.

Finding the Correct Chain

To ensure compatibility and safe operation, it is crucial to select the correct chain for your chainsaw. Refer to your chainsaw's owner's manual or the guide bar side stamp for the necessary parameters.

• Bar Length: Measure the exposed length of your guide bar. Round up to the nearest even number.
• Drive Links (DL): Count the number of drive links on your existing chain.
• Gauge: Determine the thickness of the drive link. Common measurements are .043" (1.1mm), .050" (1.3mm), .058" (1.5mm), or .063" (1.6mm).
• Pitch: Divide the distance between three rivets by two. Common sizes include .325", 3/8" LP, 3/8", and 1/4". Note that 3/8" is typically for saws >50cc, and 3/8" LP is for smaller saws.

Setup and Installation

Installing a new chainsaw chain requires careful attention to detail to ensure safety and optimal performance. Always refer to your chainsaw's specific instructions for chain replacement.

1. Prepare Chainsaw: Ensure the chainsaw is turned off, the spark plug wire is disconnected (for gas models), or the battery is removed (for electric models). Engage the chain brake.
2. Remove Old Chain: Loosen the bar nuts and remove the clutch cover. Carefully remove the old chain and guide bar.
3. Clean Components: Clean any sawdust or debris from the guide bar groove, sprocket, and clutch area.
4. Install New Chain: Place the new UPFOREST chain around the clutch sprocket, ensuring the cutters are facing the correct direction (usually forward on the top of the bar). Fit the chain into the guide bar groove.
5. Mount Guide Bar: Slide the guide bar onto the mounting studs, ensuring the chain is properly seated in the bar groove and around the sprocket.
6. Adjust Tension: Hand-tighten the bar nuts. Adjust the chain tension screw until the chain is snug but can still be pulled freely around the bar by hand. The chain should not sag on the underside of the bar, but also not be overly tight.
7. Final Tightening: While holding the tip of the guide bar up, fully tighten the bar nuts. Recheck chain tension.

Operating Instructions

Once the UPFOREST chainsaw chain is correctly installed and tensioned, follow these general operating guidelines:

• Pre-Operation Check: Before each use, verify chain tension, oil level, and ensure all components are secure.
• Proper Grip: Always hold the chainsaw firmly with both hands, maintaining a balanced stance.
• Cutting Technique: Allow the chain to do the work. Do not force the saw through wood. Maintain a steady, controlled cut.
• Avoid Kickback: Be aware of the kickback danger zone (the upper quadrant of the guide bar tip). Avoid cutting with this area.
• Lubrication: Ensure the chainsaw's automatic oiler is functioning correctly to continuously lubricate the chain and bar during operation.

Maintenance

Regular maintenance extends the life of your UPFOREST chainsaw chain and ensures safe operation.

• Chain Sharpening: Sharpen the chain regularly to maintain cutting efficiency. A dull chain requires more force, increases wear, and can be dangerous. Follow your chainsaw's manual for correct sharpening angles and file sizes.
• Lubrication: Ensure the chainsaw's oil reservoir is filled with appropriate bar and chain oil. The UPFOREST chain's integrated lubrication system works best with consistent oil supply.
• Cleaning: After each use, clean sawdust, resin, and debris from the chain, guide bar, and sprocket. This prevents buildup that can hinder performance and cause premature wear.
• Inspection: Periodically inspect the chain for stretched links, cracks, or damaged cutters. Replace the chain if significant damage is found.
• Storage: When not in use, store the chain in a clean, dry place. The protective oil on the chain helps prevent corrosion during storage.
