Final Clutch Adjustment
To check the clutch cable adjustment, proceed as follows.
•Disconnect the spark plug wire and move it away from the spark plug to prevent accidental starting.
•Engage and release the tine engagement handle, then the reverse tine engagement lever (model 390 only). If an excessive noise is heard when releasing either the tine drive clutch handle or lever, the cable may be too loose. Adjust either the forward or reverse clutch cable by loosening the hex nut, threading the rod into the cable one or two turns, then retightening the nut.
•With tine engagement handle in neutral (released) as shown in Figure 6, pull the starter rope several times. The tines should not turn. If they turn forward, loosen the hex nut on the forward cable (underneath the handle assembly). If they turn
toward the rear (model 390 only), loosen the hex nut on the reverse cable (above the handle assembly). Unthread the rod from the cable 2 or 3 turns. Retighten the hex nut, and check again for correct adjustment. See Figure 6.

Throttle Control
The throttle control lever is located on the engine. It controls the engine speed and stops the engine. See Figure 7.
Choke Lever (Model 340/390)
The choke lever is located above the throttle control. It is used to enrich the fuel mixture when starting a cold engine. See Figure 7.
Primer Button (Model 345)
The primer button is located behind the air cleaner. It is used to enrich the fuel mixture in the carburetor when starting a cold engine. See Figure 7
Forward Tine Engagement Handle
The forward tine engagement handle is located beneath the tiller handle. Squeezing the handle up against the tiller handle engages the tines. Release the handle to stop the tines. See Figure 8

The reverse tine drive clutch lever is located on top of the handle panel. Pull the lever to the rear to move the tines in reverse. Release the lever to stop the reverse tine drive. See Figure 8
NOTE: Never engage both the forward and reverse tine drives at the same time. Engaging both forward and reverse tine drives at the same time could damage the belt drives and cause the engine to stall.
