Echo has been manufacturing hand-held lawn equipment for over 30 years. They produce tools such as string trimmers, edgers, brush cutters, back pack blowers, hand-held blowers and chain saws for both residential and commercial use alike. At one time Echo tools were only available through specific Echo dealers. However, in 1994 Echo established a market through Home Depot and they now provide hand-held equipment for residential use.
The Echo 650, technically called the PB 650, is a powerful backpack blower designed for both residential and commercial use.
The PB 650 uses a 63.3 c.c. two-stroke gasoline engine. The gas must be mixed with two-stroke engine oil according to manufacturer's specifications.
This machine is capable of producing an air flow of 210 miles per hour. With the throttle held wide open the engine is capable of 7,300 revolutions per minute.
The blower weighs 23 lbs. with an empty gas tank. With a full gas tank, which holds 70 oz., the blower weighs about 27 lbs.
The Echo PB 650 made its debut in 2003. This particular model is no longer available, but has been replaced by the Echo PB 651. Both blowers are the same in nearly all respects. However, in compliance with the demands of the Environmental Protection Agency in 2002, all two-stroke engines had new carburetors installed to reduce emissions. Echo equipment is sold at Home Depot and various other authorized Echo dealers.
When properly maintained this blower will deliver years of use. After a month of daily use, replace the unit's sparkplug and fuel filter. Clean the air filter and replace if necessary. Use only high octane gas in this machine, and for best performance combine a fuel additive with the gas. When storing the blower for over a month, empty the gas tank and remove the sparkplug.
