CONTROLS

A. Choke

The choke controls the fuel to air ratio, and helps make cold starts easier by providing a rich, easily-ignited fuel mixture.

B. Throttle

The throttle controls engine speed, and allows you to conserve fuel by powering down during idle periods, or to achieve optimal chipping/shredding/vacuuming power by running the engine at full speed.

C. Vacuum Nozzle Variable Suction ControW

The vacuum nozzle Variable Suction Controlru is direct- ly above and behind the vacuum nozzle, and has four quick-set opening settings for variable nozzle suction control:

closed (for vacuuming with the optional hose attachment)

113 open,

* 213 open

full open.

Smaller nozzle openings provide the necessary vacuum force for smaller debris, while a larger opening provides the suction necessary for larger debris like large leaves.

D. Vacuum Nozzle Height Control

The vacuum nozzle height control lever is located at the rear frame in front of the discharge bag. Three height settings are available: Low, Medium, and High.

The low setting is suitable for smooth, hard surfaces, while the medium and high settings are used for differ- ent terrain conditions. Settings are easily changed by simply positioning the control lever into one of three dif- ferent slots.

The height adjustment control may be fine-tuned by means of an rod adjustment that permits precise posi- tion control for vacuuming of smooth surfaces. See the adjustment procedure in the TROUBLESHOOTING & REPAIR section.

E. Drive Speed Control

The Chipper Vacuum is self-propelled, and features three forward speeds to help match vacuuming action to surface conditions The drive speed control lever is mounted on the handle within easy reach of the opera- tor, permitting quick changes in travel speed. This fea- ture allows you to rapidly adjust to changing conditions.

F. Power Drive Bail Lever

The power drive bail lever operates the clutch, the mechanism that transfers power from the drive shaft to the transmission.

Pulling the bail lever down against the Chipper Vacuum handle engages the transmission, which drives the unit forward for vacuum/shredding or moving the unit around your yard and garden.

Releasing the lever disengages the transmission, stop- ping the power drive motion, and allowing the unit to come to a stop to make adjustments, empty the bag, or perform chipping or hose vacuuming operations.
