To keep your chipper operating well from year to year, it's a great idea to keep up with a maintenance routine.
Dirty oil, corroded spark plugs, and clogged air filters will cause your chipper to suffer serious problems.
As long as you follow routine maintenance procedures, you should get many productive years of service from your chipper shredder.
1. Drain the Oil
Find an old bowl or oil pan to drain your oil into and place it underneath the oil plug.
Usually the oil plug will require a 5/8" wrench. Loosen the plug until you can turn it with your fingers, then use your fingers to unscrew it the rest of the way to allow the oil to easily drain out.
While your oil is draining, we'll move onto the next couple of steps.
2. Check Your Air Filter
Using approximately a 5/16" socket with a socket wrench, loosen and remove the screws from the air filter cover.
Open the air filter cover and remove the filter for inspection. If it's still relatively clean, simply dust it off and put it back. If it's dirty, you can replace it or clean it.
If you use water to clean it, leave it out until it's completely dried before reinserting.
3. Check Your Spark Plug
Locate the black rubberized spark plug wire as seen in the video, and pull it free from the spark plug.
Using approximately a 5/8" socket with socket wrench, loosen and remove the spark plug.
Inspect the wide end of the spark plug for corrosion of any kind. If it's okay, reinsert and screw your spark plug into place. If it's corroded, replace it with a new one.
Once your spark plug is screwed tight into place, reattach the spark plug wire and make sure it's pushed all the way onto the plug.
4. Finish Your Oil Change
By now, your oil should be fully drained, so it's time to finish the job.
Screw the oil plug back into place and tighten it with your wrench to prevent it from shaking loose.
Locate your oil cap on the top of the unit. It's typically a yellow cap, and will usually have a dipstick attached. Remove the cap and pour the appropriate amount of manufacturer suggested oil type into your tank.
I recommend using a funnel for this processes to avoid spilling oil on everything else. With a taller funnel, you can pour more quickly without worrying about overflow.
