To engage the chain brake, simply push the front hand guard forward until it clicks. Remember, only disengage the chain brake after the engine starts and you’re prepared to work.

Key safety benefits include:

• Preventing unintended chain rotation during start-up
• Minimizing kickback risks that can cause injury
• Enhancing overall user control and confidence
• Reducing the chance of accidents caused by sudden chain movement
• Ensuring safer handling as you begin your cutting task

Always prioritize activating the chain brake as a core safety step. It really makes a difference!

Use the Decompression Valve (If Available)

If your Stihl MS170 has a decompression valve, use it to lessen engine compression and make pulling the starter rope easier. You’ll want to engage it especially when the engine is cold or if you’re struggling to start the saw.

Just press the valve firmly before pulling the rope to ensure a smoother start. It really helps make getting the engine going less of a hassle. Give it a try next time you fire up your saw!

Purpose of Valve

Although starting your Stihl MS170 can be tough because of high engine compression, using the decompression valve makes pulling the starter rope much easier. This valve plays an essential role in the starting procedure by temporarily reducing engine compression, so you don’t have to exert excessive force.

Here’s what the decompression valve does: it lowers engine compression during cold starts and allows the fuel mixture to flow more freely into the combustion chamber. This means less strain and fatigue when pulling the starter rope.

You’ll typically find the valve located near the carburetor or cylinder. Just make sure it’s fully seated before you start, or you might run into flooding or ignition issues.

Using the decompression valve properly ensures a smoother, less strenuous start every time you fire up your chainsaw. It really makes a difference when getting your saw going!

When to Use

Since starting your Stihl MS170 can be tough, especially in cold conditions or after long periods of inactivity, you’ll want to use the decompression valve to ease the effort required to pull the starter rope.

Press the decompression valve firmly before engaging the choke and pulling the starter rope to make the engine ignition smoother. Once the engine fires, release the valve to restore normal compression.

This reduces strain on your arm and helps your chainsaw start more easily. It’s a handy trick to remember whenever you’re having trouble getting your saw going.

Condition	Action
Cold weather	Use decompression valve
Difficult start	Press valve before pulling starter rope
Engine fires	Release valve
Normal operation	Valve not engaged

Prime the Carburetor With the Primer Bulb

How do you get your Stihl MS170 ready to start? First, you need to prime the carburetor using the primer bulb. This step draws fuel into the engine, making starting easier.

Here’s how to do it right: Locate the primer bulb on the side of the carburetor and check it’s clean. Press the primer bulb firmly about 5 to 10 times.

Watch for fuel entering the bulb or feel it firm up. Stop priming once the bulb feels hard to avoid flooding the engine.

After priming, you’re ready to move on to the next starting steps.

Set the Master Control to the Choke Position

Locate the master control lever on your Stihl MS170 and make sure the throttle trigger is at idle with the chain brake engaged. Then, move the lever to the choke position to prepare the carburetor for starting.

This setting restricts airflow and enriches the fuel mixture for an easier cold start. It really helps get the engine going when it’s cold outside or after the saw has been sitting for a while. Just a quick move to choke, and you’re set!

Locate Master Control Lever

Before you start the engine, you’ll need to find the master control lever on the side near the top of the engine housing. Set it to the choke position to enrich the fuel mixture for a cold start.

The master control lever is essential for starting your chainsaw correctly. Here’s how to identify and use it:

• Look on the side near the top of the engine housing.
• Find the lever labeled “Choke” or with a choke symbol.
• Push or slide the lever fully to the choke position.
• This locks the throttle closed to enrich the fuel mixture.
• Confirm it’s fully engaged before pulling the starter rope.

Setting the master control lever to choke ensures easier starting and prevents engine flooding on your Stihl MS170 chainsaw. Easy, right? Just follow these steps, and you’ll be good to go!

Adjust Lever to Choke

Once you’ve found the master control lever and set it to the choke position, it’s time to adjust it properly for starting. Move the lever fully to the choke setting, usually marked or labeled “Choke,” to restrict airflow and enrich the initial fuel mixture.

This adjustment is essential because it prepares the engine for an easier start by ensuring proper fuel combustion. Before setting the choke, make sure the throttle trigger is disengaged and resting in the idle position.

Confirm the choke is fully engaged by checking that the master control lever sits firmly in the choke position. Remember, once the engine starts, you’ll need to return the lever to the run position to allow normal operation and prevent stalling.

Position the Chainsaw on a Flat Surface

Although it might seem simple, positioning your Stihl MS170 chainsaw correctly on a flat surface is essential for safe startup. Before you start engine procedures, place the chainsaw on a flat, stable surface with the guide bar slightly elevated to avoid dirt contact.

Always verify the chain brake is engaged and the saw is off. Here’s how to position it properly:

• Set the chainsaw on a flat surface for stability
• Engage the chain brake before placing it down
• Keep the guide bar raised off the ground
• Position with the carburetor and air filter side accessible
• Clear the area of obstacles and bystanders

This setup prevents slipping and prepares you for a safe and effective start. It’s a simple step but makes a big difference!

Secure the Saw With Your Foot and Grip the Handle

When you’re ready to start your Stihl MS170, place your left foot firmly on the rear handle to keep the saw steady. This foot placement helps stabilize the chainsaw on the flat surface, preventing unwanted movement.

Next, grip the front handle with your left hand and the rear handle with your right hand. Holding both handles ensures you maintain proper control throughout the startup process.

Keep your feet shoulder-width apart to balance your body and gain better leverage. By securing the saw with your foot and firmly gripping the handles, you create a stable and controlled setup.

This foundation is vital for safely and effectively starting your chainsaw without risking slips or loss of control.

Pull the Starter Rope Until the Engine Fires

With the saw securely held and your grip firm, you’re ready to pull the starter rope. Make sure the choke is set correctly—fully engaged for cold starts, half-open or open for warm starts.

Then, pull the starter rope with a smooth, steady motion until you feel resistance. Release gently to avoid stalling. Keep pulling until the engine fires or you hear the engine attempt to start.

Remember to:

• Pull firmly but smoothly without yanking
• Release the rope gently after each pull
• Watch for engine fires or sputters

If the engine doesn’t start after several pulls, adjust the choke. And if it still won’t start after 5-6 pulls, check the fuel.

Following this ensures your Stihl MS170 starts efficiently and safely.

Gradually Increase Throttle and Release the Chain Brake

Before you increase the throttle, make sure to release the chain brake so the chain can move freely.

After the engine starts, gradually squeeze the throttle trigger to smoothly raise the chain speed. This prevents sudden chain movement and engine bogging.

Always confirm the chain brake is disengaged before applying throttle to avoid kickback.

Step	Action
1. Release Chain Brake	Ensure the brake is off
2. Gradual Throttle	Slowly increase throttle trigger
3. Check Chain Speed	Confirm desired speed before cut
