In workshops all across the country one thing seems to be similar. Participants at some point in the workshop always say “My saw doesn’t start and run like yours”.
Over the years I have operated many model saws and other two-cycle machines of several brands. I can honestly say in my findings that all of them, if understood and maintained properly, usually will outwork this operator. I’ve learned most issues arise from operator controls and maintenance or lack there of. It’s not to say the operator causes every issue but most of the time a lack of attention and or understanding is a major contributor.
I have a workshop available that covers some of these aspects in a unique tear down and inspection process. I want to highlight a few of the very important areas with this writing.
A two-cycle engine is simply an air pump. It needs air flow to mix with fuel, compression and spark to convert this mixture to usable energy. The air filter is important in maintaining this air flow. Fuel mixed properly, gasoline with lubrication, adjusted to the right amount of air is critical to efficient run, power and longevity. Engine compression creates power by manipulating the air and fuel flow. Compressing, squeezing and confining to make sure the power is harnessed and carried to the crankshaft and on to the crankshaft attachment. Ignition spark divides the intake from the exhaust. Exploding at the perfect time to turn fuel and air into burned gases. Efficient combustion is the by product of a well designed and tuned engine. If the operator doesn’t have a basic understanding of these principles it’s difficult to maintain and operate to the equipment’s potential.
So in the Troubleshooting Workshop we look at how the air filter may restrict air flow. How proper fuel mix can make or break an engine. How lubrication is utilized and how the carburetor is adjusted and is susceptible to dirt, water and too much oil. What causes an engine to seize up. What external attachments like bar and saw chain can effect. How can starting procedures effect the run and life of the equipment. What is a fast idle position?
The workshop can be accomplished at your location. Open to16 participants and requires 4hours of class time. It is all hands-on for the attendees, intertwined with lecture. A chainsaw operator with a little Saw Savvy from a Trouble Shooting Workshop will be an operator with less equipment issues, better safety awareness and improved productivity.
