Safety Instructions

Read all instructions before use. Always wear appropriate safety gear.

1. Personal Protective Equipment (PPE): Wear safety glasses, hearing protection, gloves, steel-toe boots, and close-fitting clothing.
2. Work Area Safety: Ensure clear area, stable footing, and no bystanders or pets within 15 feet.
3. Electrical Safety: Use grounded outlet; keep cord away from cutting area and sharp objects.
4. Kickback Awareness: Hold saw firmly with both hands; do not cut with tip of bar.
5. Chain Brake Test: Test before each use by engaging brake with front hand guard.

WARNING! Failure to follow safety instructions can result in serious injury or death. Never operate while tired or under the influence.

Assembly & Setup

Unpack and inspect all parts. Assemble on a clean, flat surface.

1. Attach guide bar and chain: Place bar onto mounting studs, loop chain around bar sprocket and drive sprocket, ensure cutting teeth face forward on top.
2. Adjust chain tension: Turn tensioning knob clockwise until chain fits snug against bar but can be pulled by hand.
3. Fill oil reservoir: Use only recommended bar and chain oil; fill to level indicated in window.
4. Plug in and test: Connect to grounded outlet, press lock-off button, squeeze trigger to test run (no cutting).

CAUTION! Ensure chain is properly tensioned. Loose chain can derail; overtightened chain can damage motor.

Operation Guide

For cutting logs, pruning branches, and limbing.

1. Starting Cut: Hold saw firmly, let chain reach full speed before contacting wood.
2. Basic Cutting: Use middle of bar; avoid tip to prevent kickback.
3. Bucking (cutting fallen logs): Support log off ground; cut from top down.
4. Limbing (removing branches): Cut from bottom of tree upward; watch for spring-back.
5. Pruning: Make relief cuts for heavy branches to prevent tearing.
6. Oiling During Use: Automatic oiler lubricates chain; check oil level frequently.

Tip: Let the saw do the work; do not force it. Keep chain sharp for best performance.

Maintenance & Cleaning

Regular maintenance ensures long life and safe operation.

1. After Each Use: Clean sawdust from bar groove, oil ports, and motor vents with brush.
2. Weekly: Check chain tension and adjust if loose; inspect bar for wear or damage.
3. Monthly: Clean air filter (if applicable); inspect power cord for damage.
4. Oil System: Clean oil tank every few months; use only recommended oil to avoid clogs.

CAUTION! Always unplug saw before performing any maintenance or cleaning.

Chain Sharpening & Replacement

A sharp chain cuts efficiently and safely.

1. Sharpening: Use round file matching chain pitch (typically 5/32"). File each cutter at 30° angle, maintaining equal length on all cutters.
2. Depth Gauge Setting: Use flat file to maintain proper depth gauge clearance (0.025").
3. Replacement: When cutters are worn beyond repair, replace chain with identical specification (pitch, gauge, drive link count).
4. Bar Maintenance: Flip bar periodically for even wear; replace if groove is deep or edges rounded.

WARNING! Wear heavy gloves when handling chain. Dull chain increases kickback risk.

Storage Guidelines

Proper storage prevents damage and corrosion.

1. Clean saw thoroughly, removing all sawdust and debris.
2. Empty oil tank or fill completely to prevent moisture buildup.
3. Remove chain, clean, and coat with light oil; store separately if desired.
4. Store in dry, cool place, out of reach of children.
5. Loop power cord loosely; avoid sharp bends.

CAUTION! Do not store with fuel (not applicable) or in damp areas. Protect from extreme temperatures.
