STARTING
PUT OIL IN ENGINE BEFORE STARTING.
Inspect machine work area and machine before operating. Make sure that all operators of this equipment are trained in general machine use and safety.
ENGINE: See engine manufacturer’s instructions for type and amount of oil and gasoline used. Engine must be level when checking and filling oil and gasoline.
ENGINE SPEED: Controlled by throttle lever on the vac housing. Under normal conditions, operate at minimum throttle to accomplish your current cleaning task.
INTAKE HOSE: Hose mounting assembly must be properly attached to vac housing and safety switch must be engaged before engine will start. Note: Any damage to the switch or wiring harness will prevent engine from starting.
CHOKE: Located on the vac housing as part of the engine control panel.
THROTTLE: Move throttle control to fast position.
KEY SWITCH: Turn to start position until engine begins to fire, immediately release the key to the run position.
Note: Do not hold key in start position more than 10 seconds per attempt.
IF YOUR UNIT FAILS TO START:
See Troubleshooting on page 12. Also see engine owner's manual.
OPERATION
DO NOT OPERATE UNLESS
DEBRIS IS DISCHARGING
INTO AN ENCLOSED
CONTAINER
KEEP ENGINE CLEAN OF DEBRIS
EXHAUST DIRECTION & DISTANCE: Exhaust direction and distance are controlled by the angle of the exhaust deflector and by rotation of the exhaust elbow. Adjust the angle of the exhaust deflector to control the distance that debris is dis- charged. Typically debris is aimed to discharge to the rear of the container. The direction of discharge is adjusted by loosening the knobs on the exhaust elbow clamp and rotating the elbow to the desired direction.
NOTE: Elbow is heavy. Use caution when adjusting. Never stand directly under the elbow while adjusting direction of exhaust.
Never adjust exhaust deflector angle or direction of discharge while unit is running.
Never direct exhaust into an area where bystanders may cross the path of the debris.
INTAKE OPERATION: With machine running and fully assembled, move the nozzle in sweeping motions over debris. Always allow air to flow into the nozzle along with the debris. Do not completely block the nozzle when vacuuming, it will reduce performance, and increase clogging (See figure 3).
For removal of heavier debris, or debris that is stuck to the ground, rock nozzle forward to concentrate suction power around the debris (See figure 4).

HOSE CARE & USE TIPS
THE HOSE IS A REPLACEABLE WEAR ITEM.
FOR BEST HOSE OPERATION RESULTS, FOLLOW THESE RECOMMENDATIONS.
Be sure the hose is correctly installed by checking that the arrow printed on the hose indicating flow direction is pointing toward the vac housing.
Keep hose as straight as possible and avoid sharp bends during operation for best
Never drag hose. Always remove and store hose before transporting unit.
Store hose straight and flat to maintain flexibility for next use.
To increase hose life, periodically rotate hose and reposition nozzle and coupler on front plate of unit. This increases hose life by keeping hose from wearing only on one side.
