Milwaukee Pruning Saw M18 Review (7 Pro Tips for Woodworkers)

The Milwaukee M18 FUEL Pruning Saw: 7 Pro Tips for Woodworkers

As a woodworker, I know how crucial having the right tools can be. I’ve spent years felling trees, processing timber, and preparing firewood. My trusty chainsaw is always close by, but sometimes, something smaller, more agile, and equally powerful is needed. That’s where pruning saws come in, and the Milwaukee M18 FUEL Pruning Saw has seriously impressed me.

Before diving into the review, let me tell you about my old dog, Buster. He was a lumberjack’s best friend, always by my side in the yard. Sadly, he passed away last year, but he taught me a lot about patience and the importance of a job well done. Like Buster, the right tool can make any task easier and more enjoyable.

This guide provides an in-depth look at the Milwaukee M18 FUEL Pruning Saw, sharing my experiences and offering pro tips to help you decide if it’s the right addition to your arsenal.

Why a Pruning Saw? My First Encounter

I remember the first time I realized the value of a good pruning saw. I was helping a friend clear some overgrown branches from his apple orchard. Initially, I thought my chainsaw would handle everything. But it was overkill for the smaller branches, and maneuvering it in tight spaces was a nightmare. That’s when I borrowed a pruning saw, and the difference was night and day. Lighter, more precise, and safer for delicate work – I was sold.

Unboxing and First Impressions: The Milwaukee M18 FUEL Pruning Saw

The Milwaukee M18 FUEL Pruning Saw is a compact, battery-powered tool designed for pruning branches, limbing trees, and light wood cutting tasks. My first impression was of its solid build quality. It feels robust in hand without being overly heavy. The M18 battery platform is a huge plus for me, as I already have several Milwaukee tools using the same batteries.

The kit typically includes:

• The M18 FUEL Pruning Saw
• A 6″ Oregon bar and chain
• A scabbard
• A small container of bar and chain oil
• (Usually) one or two M18 batteries and a charger (depending on the kit)

The tool’s compact size makes it easy to maneuver in tight spaces, while the FUEL technology promises power and runtime comparable to some gas-powered alternatives.

Pro Tip #1: Battery Selection Matters

The M18 FUEL Pruning Saw works with all Milwaukee M18 batteries, but I’ve found that the higher-capacity batteries (like the 5.0Ah or 8.0Ah) provide significantly longer runtime. With a 5.0Ah battery, I can typically get through a full day of pruning without needing to recharge.

• 5.0Ah Battery: Good for moderate use, offering a balance between weight and runtime.
• 8.0Ah Battery: Ideal for heavy-duty tasks and extended use, providing maximum runtime.
• 2.0Ah Battery: Lightweight option for quick tasks, but runtime is limited.

My experience: Using a 2.0Ah battery, I managed about 45 minutes of continuous cutting through 4-inch thick oak branches. Switching to a 5.0Ah battery tripled the runtime to over two hours under similar conditions.

Key Features and Specifications

Here’s a breakdown of the M18 FUEL Pruning Saw’s key specifications:

• Bar Length: 6 inches
• Chain Speed: 5 m/s (meters per second)
• Weight (with battery): Approximately 5.3 lbs (with a 5.0Ah battery)
• Chain Gauge: 0.043″
• Chain Pitch: 3/8″ Low Profile
• Oil Capacity: 50 ml (approximately)
• Automatic Oiler: Yes
• Tool-Free Chain Tensioning: No

The 6-inch bar length is perfect for pruning branches up to 4-5 inches in diameter. While it’s not designed for felling large trees, it excels at limbing and trimming.

Performance in the Field: My Real-World Testing

I’ve put the M18 FUEL Pruning Saw through its paces on various wood types, including:

• Softwoods: Pine, Fir, Spruce (easy cutting, fast chain speed)
• Hardwoods: Oak, Maple, Ash (requires more patience, but still effective)
• Fruit Trees: Apple, Cherry, Pear (excellent precision, clean cuts)

In each case, the saw performed admirably. The chain speed is sufficient for quickly cutting through smaller branches, and the motor provides enough torque to handle thicker limbs without bogging down.

Pro Tip #2: Chain Maintenance is Crucial

Like any chainsaw, proper chain maintenance is essential for optimal performance. This includes:

• Regular Sharpening: A sharp chain cuts faster, smoother, and safer. I recommend sharpening the chain every few hours of use, or whenever you notice a decrease in cutting performance.
• Proper Tensioning: A properly tensioned chain prevents excessive wear and tear on the bar and chain. The chain should be snug on the bar but still able to be pulled around by hand.
• Adequate Oiling: The automatic oiler keeps the chain lubricated, reducing friction and extending its lifespan. Always check the oil level before each use and refill as needed.

My experience: I once neglected to sharpen the chain for an extended period, and the saw struggled to cut through even small branches. After sharpening the chain, the saw performed like new.

Comparing to Gas-Powered Pruning Saws

One of the biggest advantages of the M18 FUEL Pruning Saw is its convenience compared to gas-powered models. No more mixing fuel, dealing with exhaust fumes, or struggling to start a cold engine. The M18 FUEL Pruning Saw starts instantly with the push of a button.

Here’s a quick comparison:

While gas-powered saws may offer slightly more power, the M18 FUEL Pruning Saw is a more convenient and environmentally friendly option for most pruning tasks.

Pro Tip #3: Safe Cutting Techniques

Safety is paramount when using any chainsaw. Here are some essential safety tips:

• Wear appropriate PPE: This includes safety glasses, hearing protection, gloves, and sturdy footwear.
• Maintain a firm grip: Use both hands to control the saw, and keep your fingers wrapped firmly around the handles.
• Keep your body balanced: Avoid overreaching or cutting in awkward positions.
• Be aware of your surroundings: Make sure there are no people, pets, or obstacles in your cutting area.
• Avoid kickback: Kickback occurs when the tip of the bar contacts a solid object, causing the saw to suddenly kick back towards the operator. Be especially careful when cutting near knots or other obstructions.

My experience: I once experienced kickback when cutting a branch that was under tension. Fortunately, I was wearing safety glasses and gloves, which protected me from injury.

Disadvantages and Potential Drawbacks

While the M18 FUEL Pruning Saw is an excellent tool, it’s not without its drawbacks:

• Limited Bar Length: The 6-inch bar length may be too short for some tasks.
• No Tool-Free Chain Tensioning: Adjusting the chain tension requires a wrench, which can be inconvenient.
• Price: The M18 FUEL Pruning Saw is more expensive than some gas-powered alternatives.

However, for most woodworkers and homeowners, the advantages of the M18 FUEL Pruning Saw outweigh these drawbacks.

Pro Tip #4: Mastering the Art of Limbing

Limbing is the process of removing branches from a felled tree. The M18 FUEL Pruning Saw is perfectly suited for this task. Here are some tips for effective limbing:

• Start from the bottom: Begin by removing the lower branches and work your way up the tree.
• Cut on the outside of the branch collar: The branch collar is the swollen area where the branch joins the trunk. Cutting outside the collar promotes faster healing.
• Use a three-cut method for larger branches: This prevents the bark from tearing and damaging the trunk. First, make an undercut about one-third of the way through the branch, a few inches from the trunk. Then, make a top cut a few inches further out. Finally, make a flush cut just outside the branch collar.

My experience: I once used a chainsaw to limb a tree without using the three-cut method, and the bark tore badly. The tree took much longer to heal, and the wound was more susceptible to disease.

Understanding Wood Types and Their Impact on Cutting

The type of wood you’re cutting can significantly impact the performance of the M18 FUEL Pruning Saw.

• Softwoods: Generally easier to cut due to their lower density. Pine, fir, and spruce are common softwoods.
• Hardwoods: More difficult to cut due to their higher density. Oak, maple, and ash are common hardwoods.
• Green Wood: Wood that has not been dried. Green wood is often easier to cut than dry wood, but it can be heavier and more prone to warping.
• Dry Wood: Wood that has been seasoned or kiln-dried. Dry wood is lighter and more stable than green wood, but it can be more difficult to cut.

My experience: I once tried to cut through a large oak log that had been drying for several years. The saw struggled to make progress, and the chain quickly dulled. After switching to a freshly sharpened chain and taking my time, I was able to complete the cut.

Pro Tip #5: Sharpening Techniques for Optimal Performance

A sharp chain is essential for efficient and safe cutting. Here are two common methods for sharpening chainsaw chains:

1. Hand Sharpening: Using a file and guide, you can sharpen the chain by hand. This method is more time-consuming but allows for greater precision.
2. Electric Chain Sharpener: An electric chain sharpener makes quick work of sharpening the chain. This method is faster but can be less precise.

My experience: I prefer to sharpen my chains by hand because I find that I can achieve a sharper edge and maintain the correct cutting angle. However, an electric sharpener can be a good option for those who are new to chainsaw sharpening or who need to sharpen chains frequently.

The Importance of Bar and Chain Oil

Proper lubrication is crucial for extending the life of the bar and chain. Use a high-quality bar and chain oil specifically designed for chainsaws. Avoid using motor oil or other substitutes, as they may not provide adequate lubrication.

• Viscosity: The oil should have a viscosity that is appropriate for the temperature and type of wood you are cutting.
• Tackiness: The oil should be tacky enough to cling to the bar and chain, even at high speeds.
• Biodegradability: Consider using a biodegradable bar and chain oil to reduce your environmental impact.

My experience: I once used a cheap bar and chain oil that was too thin, and the chain quickly overheated and wore out. After switching to a high-quality oil, the bar and chain lasted much longer.

Pro Tip #6: Storing Your Pruning Saw Properly

Proper storage can help extend the life of your M18 FUEL Pruning Saw.

• Clean the saw: Remove any sawdust or debris from the saw after each use.
• Empty the oil reservoir: This prevents the oil from gumming up the oiler.
• Store the saw in a dry place: Moisture can cause rust and corrosion.
• Remove the battery: Storing the saw with the battery attached can drain the battery and shorten its lifespan.
• Use the scabbard: The scabbard protects the bar and chain from damage.

My experience: I once stored my chainsaw in a damp shed, and the bar and chain quickly rusted. After cleaning and lubricating the saw, it was still usable, but it never performed as well as it did before.

Advanced Techniques: Notching and Felling Small Trees

While the M18 FUEL Pruning Saw is primarily designed for pruning and limbing, it can also be used for felling small trees. However, this should only be attempted by experienced users who are familiar with safe felling techniques.

• Notching: The notch is a wedge-shaped cut that determines the direction of the fall. The notch should be cut on the side of the tree that you want it to fall towards.
• Back Cut: The back cut is made on the opposite side of the tree from the notch. The back cut should be made slightly higher than the bottom of the notch.
• Felling Wedge: A felling wedge can be used to help direct the fall of the tree. The wedge is inserted into the back cut and driven in with a hammer.

My experience: I once felled a small tree without using a felling wedge, and the tree fell in an unexpected direction. Fortunately, no one was injured, but the experience taught me the importance of using proper felling techniques.

Pro Tip #7: Troubleshooting Common Problems

Even with proper care and maintenance, problems can sometimes arise. Here are some common problems and their solutions:

• Saw won’t start: Check the battery, chain brake, and on/off switch.
• Saw cuts slowly: Sharpen the chain or replace it if it’s worn out.
• Chain is loose: Adjust the chain tension.
• Saw is smoking: Check the oil level and make sure the chain is properly lubricated.
• Saw is overheating: Allow the saw to cool down and check the chain tension and lubrication.

My experience: I once had a chainsaw that kept stalling. After checking the fuel filter and air filter, I discovered that the spark plug was fouled. Replacing the spark plug solved the problem.

Firewood Preparation: From Tree to Hearth

The M18 FUEL Pruning Saw is a valuable tool for preparing firewood. It can be used to:

• Limb felled trees: Remove the branches from the trunk.
• Cut logs into manageable lengths: Cut the logs into lengths that are appropriate for your fireplace or wood stove.
• Split logs: While the pruning saw isn’t ideal for splitting logs, it can be used to create starter splits for larger logs.

My experience: I use my chainsaw and pruning saw in conjunction to process firewood. The chainsaw handles the larger cuts, while the pruning saw is perfect for smaller branches and detailed work.

Measuring Success: Metrics for Wood Processing

To gauge the efficiency and effectiveness of your wood processing efforts, consider tracking these metrics:

• Processing Time: How long does it take to process a given volume of wood?
• Wood Moisture Content: What is the moisture content of the wood after drying?
• Equipment Maintenance Schedule: Are you adhering to a regular maintenance schedule for your tools?
• Firewood Yield: How much firewood are you producing from a given amount of raw timber?

My experience: By tracking these metrics, I’ve been able to identify areas where I can improve my efficiency and reduce waste.

The Future of Battery-Powered Wood Processing Tools

Battery-powered tools are constantly evolving, and I expect to see even more powerful and versatile models in the future. Advancements in battery technology will lead to longer runtimes and faster charging times. Brushless motors will become even more efficient, providing more power with less energy consumption.

My prediction: Within the next few years, battery-powered chainsaws and pruning saws will rival the performance of their gas-powered counterparts in all but the most demanding applications.
