2. On the PRO model:
Prime the engine. Push the black primer bulb (Figure 17) for three seconds and completely
release it, letting it pop back to its original position. Repeat three to four times.
The Commercial model does not have a primer.
Note: Priming is usually unnecessary when restarting a warm engine. In cool weather
priming may need to be repeated
3. Grasp the recoil starter handle (Figure 16), and slowly pull until resistance is felt. Let the
cord retract a little bit, then pull the cord rapidly to start the engine. One or two pulls usually

, but it may be necessary to repeat the priming (on
PRO models).
Stopping the Engine
Move the throttle lever (Figure 16) back to the STOP position.
Note that on Electric-Starting models the key does not stop the engine. You must throttle down.
The key has a pressure lock that prevents it from vibrating loose during operation. If you wish to
remove the key, push it in and then quickly and firmly pull it out. If the key is difficult to
remove, spray FLUID FILM

or a comparable lubricant into the keyhole.
Engaging the Trimmer Head
1. Bring the bail bar (Figure 16) toward you and grip it together with the handlebar. Keep
holding the bail bar to the handlebar.
2. With your right hand, push the trimmer head control lever (marked "Blade Control") on the
right side of the handlebar all the way forward—until it engages. You may have to push hard
until you feel it engage. Once the trimmer head control engages, release the lever and
continue to hold the bail bar. The cutting cords will now be rotating and will continue to
rotate until you release the bail bar.
Stopping the Cords Spinning
Release the bail bar from the handlebar. The trimmer head will stop spinning while the engine
continues to run.
If the trimmer head keeps spinning after the bail bar is released you may need to adjust the
trimmer control cable. See page 28.
