Operation Instructions

WARNING

Before operating or using the sweeper, review the instructions below and safety information. Failure to follow these instructions may result in property damage or injury to the operator or bystanders.

Attach the Sweeper to the Towing Vehicle

On a level surface, line up the towing vehicle with sweeper. Use the hitch pin and spacers to adjust the height of the tow hitch, as shown in the diagram. Once adjusted, insert the cotter pin (R Pin Ø2) to secure the hitch pin. For best results, the hopper should be level with the ground at a minimum clearance of 5". Secure the rope to the tow vehicle.

Diagrams show the process of aligning the towing vehicle with the sweeper and adjusting the hitch height using pins and spacers, ensuring a minimum 5-inch clearance and securing the hitch pin with an R Pin (Ø2). The rope is secured to the tow vehicle.

Adjust the height of the Brushes

Use the height adjustment handle to set the height of the brushes. For optimal results, the brush height should be ½" below the tips of the grass. For sweeping other materials, you may need to adjust the height of the brushes.

Towing the Sweeper

Your sweeper is designed to work at speeds of 5mph and lower. You may damage the device or experience sub-optimal results if exceeding 5mph. Your sweeper will work best on flat, smooth surfaces. If operating on a slope, always tow the sweeper up or down the surface of the hill, not sideways along the slope.

Dumping the Hopper

When dumping the hopper, use the rope to pull the basket forward. Dump the hopper regularly for best performance.

CAUTION

Never attach the hopper rope to any part of your body or clothing. Never hold onto the rope while towing the sweeper. Only attach the rope to the tow vehicle to keep it away from the wheels and rotating parts. Keep sweeper away from fire or excessive heat will cause damage to the brushes and bag.

Maintenance and Storage

WARNING

Improper maintenance and storage of the sweeper may void your warranty.

MAINTENANCE

• After each use clean material out of hopper.
• Rinse/dry inside and outside of the sweeper after each use.
• Remove any material which has wrapped around the brushes.
• Periodically check all fasteners for tightness.
• Twice a year apply a few drops of light multipurpose oil to the brush shaft bearings.
• Annually clean and lightly lubricate all moving parts.
• Every two years remove and clean gears and apply an even coat of light synthetic grease.
• Use a glossy enamel spray paint to touch up scratched or worn painted metal surfaces.
• Never exceed the hopper load capacity rating; it will damage the bag.
• Regularly grease axle and wheel bearing area or when needed.

LUBRICATION

The bearings in the sweeper have been pre-lubricated at the factory; however, it is recommended that a few drops of light multipurpose oil should be added to the brush shaft bearings twice a year. Also, the wheels should be removed to clean gears every two years. After cleaning apply an even coat of light synthetic grease.

NOTE: To remove wheel, use a screwdriver to pop off hub cap, remove the lock nut and washer.

Diagram shows a close-up of a wheel hub area with labels: HEIGHT ADJUSTMENT SLOT, FLAT WASHER, LOCK WASHER, OIL BEARING, HEX BOLT.

WHEEL GEARS/PAWL SERVICE

DO NOT remove both wheels at the same time. Remove one wheel at a time to prevent using the wrong parts for the opposite side (left and right sides are different). When removing gears, make notes on position of all washers and other parts.

Diagram shows RATCHET GEAR and DRIVE PIN components.

BRUSH REPLACEMENT

1. Remove the hopper bag from lawn sweeper.
2. Only replace one brush at a time.
3. Tip the sweeper forward on housing. Do not remove the hex bolts from double brush retainers.
4. Loosen hex bolts and hex lock nuts from single brush retainers. Slide brush out of retainers, making note of over-lap bristles position.
5. Install new brush, make sure the over-lap bristles are in the positioned as before.

Diagram shows BRUSH ROTATION, OVERLAP BRISTLES, BRUSH RETAINERS, and BRUSH SHAFT.

IMPORTANT: If a part needs replacement, only use parts that meet the manufacturer's specifications. Replacement parts that do not meet specifications may result in a safety hazard or poor operations.

WARNING

Before storing the sweeper always empty the hopper bag to avoid spontaneous combustion.

STORAGE

• Empty hopper bag before storing the sweeper.
• Clean the sweeper and hopper thoroughly to help prevent rust and mildew.
• Before storing, make sure the sweeper is clean and dry for years of trouble-free service.
• Collapse the hopper bag for storage, remove the two support rods from the rear of the hopper.
• Lightly lubricate all sweeper surfaces and moving parts to prevent rust.
• Store indoors or protected area during severe weather and winter months.
