How to Start a Chainsaw Safely

Starting a petrol chainsaw correctly and safely is essential for both performance and personal protection. Whether you're a first-time user or just need a refresher, this guide walks you through the proper steps to safely start your SHAYN chainsaw.

Before You Begin: Pre-Start Safety Checks

• Check that the chain brake is engaged (push forward).
• Ensure the chain is properly tensioned and lubricated.
• Inspect the fuel tank — use fresh fuel mixed at a 25:1 ratio (100ml of 2-stroke oil per 2.5L of petrol).
• Confirm bar and chain oil is topped up.
• Wear all appropriate PPE: gloves, eye protection, ear protection, cut-resistant trousers, and boots.

Step-by-Step: Cold Start Procedure

1. Place the chainsaw on a flat, stable surface. Ensure the chain is not touching anything.
2. Engage the chain brake. Push the front hand guard forward until it clicks.
3. Set the choke to the full position. (Usually a lever or knob — refer to your manual.)
4. Press the primer bulb. Pump it 5–6 times (if your model has one) until you see fuel inside the bulb.
5. Hold the saw down firmly. Place one foot in the rear handle and hold the top handle with your left hand.
6. Pull the starter cord briskly. Repeat until the engine "pops" or fires briefly.
7. Move the choke to the half position. Then pull the cord again — the engine should now start.
8. Let the engine run for a few seconds, then gently press the throttle once to disengage the choke.

For Warm Starts:

If the chainsaw has been used recently, skip the full choke and start with half choke or no choke depending on temperature.

Common Mistakes to Avoid

• Starting with the chain brake disengaged
• Poor footing or holding the saw in the air while starting
• Using old fuel (replace fuel every 30 days)
• Over-pulling the recoil cord (use short, controlled pulls)
