Not for the faint of heart or the inexperienced, the Stihl 044 chain saw is designed to tackle "extraordinary cutting needs," according to the manufacturer. Because this saw has a higher kickback potential than other models, it should be approached with caution even by confident users. But if your chain saw training and skill level are a "cut" above the average, this model can handle the big jobs you have.
A review of this tool's specifications gives you a shopping guide for replacement parts or helps you decide if it's a right fit for you to purchase.
A single-cylinder, two-stroke engine powers the Stihl 044.
- Piston displacement: 4.31 cubic inches
- Cylinder bore: 1.97 inches
- Piston stroke: 1.42 inches
- Idle speed: 2,500 rpm
- Maximum speed (cut-off speed): 13,500 rpm
Stihl's standard all-position diaphragm carburetor maintains a consistent fuel level to ensure the chain saw operates smoothly at all angles. Unlike conventional carburetors that have a "float" to sense the fuel level, Stihl's integral fuel pump takes its cue from the flexible disk, called a diaphragm, to detect the need for sending more fuel to the carburetor.
Air filters. The choice of air filters to keep airborne particles out of the carburetor depends on operating conditions:
- A standard wire mesh air filter is suitable for normal operating conditions and winter use.
- A protective felt prefilter covers a heavy-duty filter, suitable for dry and dusty work areas.
Fuel mixture: The Stihl 044 uses a fuel mixture of gasoline and oil with a 50:1 ratio -- mix 50 parts of gasoline with 1 part oil.
Use Stihl or a comparable two-stroke air-cooled engine oil with a "TC" classification for the mixing oil.
Only use unleaded (regular) gasoline. If the octane rating of your regular gas is lower than 89, use premium unleaded gasoline so the engine doesn't overheat.
Fuel tank capacity: 1.69 pints
Oil tank capacity: 0.7 pint
The ignition system is a breakerless electronic magneto-type.
Spark Plugs (Suppressed)
- Type: Bosch WSR 6 F or NGK BPMR 7 A
- Heat range: 200
- Electrode gap: 0.02 inch
- Spark plug thread: M14 x 1.25, 0.37 inch long
Bars and Chains
A chain saw is not a static cutting tool. The gasoline-powered engine moves the chain around a guide bar, and the embedded teeth in the chain cut the wood. The Stihl 044 is designed for different types and sizes of bars and chains.
Even when you're not using the chain saw or the engine isn't running, the sharp teeth can cut you.
- Bars: Stihl reduced kickback bar with 3/8-inch pitch -- Rollomatic with sprocket nose.
- Lengths: 16, 18 or 20 inches.
- Chains: Stihl low-kickback chain for 3/8-inch pitch -- Rapid-Micro 2 (33 RM 2, 36 RM 2).
- Chain sprocket: seven-tooth for 3/8-inch pitch spur sprocket.
- Bars: Rollomatic "S" with sprocket nose (16, 18, 20, 24, 28, 30, 32 or 36 inches) or Duromatic with Stellite-tipped nose (16, 18, 20 or 24 inches).
- Chains (3/8-inch pitch): Topic-Micro (36 TM), Topic-Super (33 TS, 36 TS), Rapid-Micro (33 RM, 36 RM, 33 RMF), Rapid-Super (33 RS, 33 RS 1, 36 RS, 36 RS 1, 33 RSL, 36 RSL, 33 RSF, 33 RSLF, 36 RSLH).
- Chain sprocket: 8-tooth for 3/8 -inch rim sprocket.
- Rear hand guard. Helps protect the operator's right hand.
- Front hand guard. The hand guard helps protect the hands from branches and keeps the left hand away from a slipped chain. The hand guard is also the lever that activates the chain brake.
- Chain brake. In case of chain saw kickback, the brake stops the chain from rotating.
- Chain catcher. Reduces injury in case the chain breaks or comes off the bar.
