The White Yard Boss 950 Chipper-Vacuum is a powerful outdoor power equipment designed for yard maintenance, specifically for chipping and vacuuming vegetation. It is equipped with an internal combustion engine and is designed to process materials like branches, leaves, and twigs found in a normal yard.

Function Description:

The primary function of the Yard Boss 950 is to chip and vacuum vegetation. It features a chipper chute for feeding larger materials like branches (up to 3 inches in diameter) and a vacuum nozzle for collecting leaves and smaller debris. The unit is self-propelled, featuring a shift lever that controls ground speed with six forward and two reverse positions. The drive clutch handle engages and disengages the wheel drive, allowing the operator to control the unit's movement. Processed material is collected in a vacuum bag, which can be easily emptied through a large zipper. The unit also includes a flail screen in the discharge area, which helps in shredding material and preventing clogging.

Important Technical Specifications:

• Engine: Internal combustion engine (shipped without gasoline or oil; refer to separate engine manual for specifics).
• Chipping Capacity: Up to 3 inches in diameter for branches.
• Drive System: Self-propelled with a shift lever offering six forward speeds (1-slowest, 6-fastest) and two reverse speeds (R-faster of the two).
• Safety Features:
  • Nozzle or optional hose attachment must be properly affixed to depress a safety switch for the engine to start.
  • Vacuum bag and discharge chute must be properly affixed.
  • Rotating blades inside, requiring hands and feet to be kept clear of all openings.
  • Tamper plug for the chipper chute (if equipped) to push material safely.
  • Spark arrester for the muffler (required in some regions).
• Weight: Not explicitly stated, but implies a substantial weight given the self-propelled feature and engine size.
• Dimensions: Not explicitly stated.

Usage Features:

• Assembly: Requires assembly of front wheels, nozzle, chipper chute, support bracket, and clutch cable. Detailed instructions are provided for each step, including specific tools required (wrenches, pliers, funnel).
• Fuel and Oil: Requires gasoline and oil as per the separate engine manual. Emphasizes not to overfill oil and to refuel outdoors with a cool engine, away from open flames.
• Starting the Engine: Involves attaching the spark plug wire, ensuring the drive clutch handle is disengaged, setting the choke (if applicable) and throttle to FAST, placing a foot on the left rear wheel for stability, and pulling the starter rope with a rapid, continuous stroke.
• Stopping the Engine: Move the throttle control lever to the OFF position and disconnect the spark plug wire.
• Engaging Drive: With the engine running at top speed, select a desired speed with the shift lever and squeeze the drive clutch handle against the upper handle.
• Chipping: Feed vegetation up to 3 inches in diameter into the chipper chute. Use the tamper plug to push material.
• Vacuuming: Adjust the nozzle height using the height adjustment knob. Raise for thick layers of leaves, lower for smooth surfaces.
• Bag Emptying: Open the large zipper on the vacuum bag. Ensure the zipper is closed during operation.
• Safety Precautions: Emphasizes wearing safety glasses or goggles, sturdy work shoes, and close-fitting clothing. Avoid loose clothing or jewelry. Keep hands, feet, and body clear of rotating parts and openings. Never operate without guards and safety devices in place. Stop the engine and disconnect the spark plug wire before clearing clogs or performing maintenance.

Maintenance Features:

• General Cleaning: Clean the unit thoroughly after each use, including washing the vacuum bag (allow to dry in shade).
• Lubrication:
  • Rear wheels: A few drops of SAE 30 oil once a season.
  • Height Adjustment Mechanism: Light oil on pivot points once a season.
• Engine Maintenance: Refer to the separate engine manual for specific instructions.
• Flail Screen: If the discharge area clogs, remove the vacuum bag, discharge chute, and flail screen to clean. Reassemble with the curved side down.
• Chipper Blades: Keep blades sharp for best performance. Instructions are provided for sharpening or replacing blades, which involves removing the belt cover and access plate. Blades must be reassembled with the sharp edge facing upward.
• Friction Wheel Rubber: Check after 50 hours of operation for wear or cracking. Replacement involves draining fuel and oil, tipping the unit, removing the frame cover, hex shaft, and friction wheel assembly.
• Belt Removal and Replacement: Detailed steps include removing the belt cover, draining fuel and oil, tipping the unit, removing the frame cover, idler pulley bracket, engine pulley, and then the belt. Reassembly is in reverse order, ensuring the support bracket rests on the stop bolt.
• Shift Rod Adjustment: If forward or reverse movement is incorrect, adjust the shift rod by removing the bag, hairpin clip, and ferrule, setting the shift lever to 6th position, and threading the ferrule until it aligns with the upper hole.
• Clutch Cable Adjustment: Adjust hex nuts at the cable bracket to ensure no slack but not overtightened. Test by pushing the unit with the handle released (should move freely) and engaged (wheels should lock up).
• Carburetor Adjustment: Minor adjustments may be needed for fuel, temperature, altitude, or load. Refer to the engine manual. Ensure the air cleaner is clean.
• Off-Season Storage: Clean the exterior, refer to the engine manual for storage instructions, wipe with an oiled rag to prevent rust, and store in a dry, clean area away from corrosive materials.
