13.Blade Guard – Covers saw blade.

14.Front Handle – When lifting or carrying of the saw is required, use this handle.

15.Throttle Lock Lever – Using your thumb, press this lever downward and squeeze the trigger lever to lock the throttle in place.This will allow the saw blade to rotate at maximum speed without having to hold the trigger lever. Squeeze the trigger lever again to unlock the throttle.

16.Variable Throttle Lever – To obtain a variable blade speed, press this lever downward then squeeze the throttle trigger.

17.Throttle Trigger Lever – Squeeze this lever to start the saw blade rotation. Release the trigger lever to stop the saw blade rotation. This lever is to be used in conjunction with either the throttle lock or variable throttle levers.

18. Fuel Filler Cap – Remove this cap to add mixed fuel (requires a 50:1 mixture) to the fuel tank.This saw uses a 2-stroke engine. Make sure fuel cap is tightened securely. DO NOT over fill.See Figure 25 for correct fuel to oil mixture.

19. Recoil Starter (pull rope) – Manual-starting method. Pull the starter grip until resistance is felt, then pull briskly and smoothly.

20. Blade Shaft Nut – Loosen to remove the cutting blade from the outer and inner flanges.

21.Cutting Blade – Use appropriate type blades for desired cutting application.

22. Spark Plug – Provides spark to the ignition system. Set spark plug gap to 0.02 inch (0.5 mm). Clean spark plug once a month.
