A DIY Guide: How to Fix Your Demolition Saw (Local Tips & Reviews)

Demolition saws are essential equipment when it comes to construction and renovation projects. Whether you’re a professional contractor or a DIY enthusiast, you’re likely to use a demolition saw at some point. Demolition saws are tough, high-powered tools that can cut through almost any material, including concrete, bricks, and stone. However, like all equipment, demolition saws can experience wear and tear or breakdowns that affect their functionality.

If your demolition saw has stopped working, don’t panic. With a little bit of patience and technical knowledge, you can fix the saw yourself. In this DIY guide, we’ll take you through the steps for how to fix your demolition saw so it can be back in action in no time.

Step One: Tools and Materials

To fix your demolition saw, you’ll need a few tools and materials. These include:

– A socket wrench set
– Screwdrivers
– Allen wrenches
– Replacement parts, if necessary (depending on the issue you’re dealing with)
– Lubricant
– Cleaning supplies

Step Two: Diagnose the Problem

First, you need to figure out what’s causing your demolition saw to malfunction. Some common issues include:

– The saw won’t start: If your saw won’t start, check the power cord, circuit breaker, and reset button. Ensure that there’s enough gas, oil, or coolant in the saw as applicable. If the saw is still not starting, the probable causes include a faulty spark plug, carburetor, or ignition coil. Also, check the air filter and fuel lines for blockages or wear.
– The saw is not cutting properly: Consider if the blade is dull or worn out, which can cause the saw to cut poorly or stop altogether. You can sharpen the blade or replace it if it’s damaged beyond repair. Alternatively, the blade bolts may be loose and need tightening or the blade guard may be preventing the blade’s free movement, leading to a jam.
– The saw is overheating: The main culprits for overheating are damaged or worn-out seals, worn clutch plates, or a clogged air filter. Remove dirt and debris from the filter, inspect the seals for blowouts or wear and replace if needed, and lubricate the clutch to prevent it from slipping.
– The saw is vibrating excessively or making unusual sounds: Excessive vibrations, a knocking sound, or rattling may be caused by loose parts, worn bearings, or misaligned components. Tighten bolts or screws, and replace any worn bearings, bushes and spindles, etc., or take the saw to a professional for fine-tuning.

Step Three: Disassemble the Demolition Saw

Use appropriate tools and experience to take apart the saw and reach the problem area. Check the owner’s manual to ascertain the right steps to remove the parts or ask an experienced professional to guide you. Be careful to keep track of all disconnected parts and screws to avoid losing or forgetting any.

Step Four: Clean and Reassemble the Saw

The next step is to clean each part individually before putting it back together. Wipe off dirt and debris using a clean cloth or brush, and use lubricant to ensure the bearings, bushes, or other components are well-oiled before reassembly. Avoid using water or soap to clean the saw as it can cause the surface to corrode.

Once you’ve cleaned and lubricated everything, carefully re-attached all the parts and screws into their original positions, making sure that they fit snugly and are properly tightened.

Step Five: Test the Demolition Saw

Put the saw back together and then test it to see if the problem is resolved. Try turning it on and cutting something to see if it’s working correctly. If there are still issues with the saw, re-examine the maintenance manual to ensure that you didn’t miss anything.


Repairing your demolition saw may seem daunting, but it’s possible to do so with a lot of patience and effort. Keep in mind that safety should always be a top priority when fixing a saw. If you’re unsure about anything, seek professional help or advice to avoid accidental injuries while performing DIY repairs. Finally, before you start any repairs, ensure that the saw is unplugged, turned off, or removed from any power source to prevent electrocution.
