RYOBI 40V Power Head (Model RY40002)

Function Description:

The RYOBI 40V Power Head is a versatile, battery-powered tool designed to operate various EXPAND-IT attachments, including string trimmers, blowers, edgers, and cultivators. It serves as the core power unit for these interchangeable gardening tools, providing the necessary power for different outdoor tasks. The power head is engineered for dependability, ease of operation, and operator safety, aiming to provide years of rugged, trouble-free performance when properly cared for.

Important Technical Specifications:

Power Source: 40V Lithium-Ion battery pack (sold separately).
Compatibility: Designed exclusively for use with specified RYOBI EXPAND-IT attachments (RY15518 Edger, RY15519 Blower, RY15523 and RY15523A Straight Shaft String Trimmer, RY15525 Curved Shaft String Trimmer, RY15550 Cultivator).
Speed Control: Variable speed switch trigger, delivering higher speed with increased trigger pressure.
Safety Features: Trigger lock-out to prevent accidental starting.
Assembly: Requires assembly of the front handle and attachment.
Battery Installation: Features a battery port with grooves for aligning and securing the battery pack.

Usage Features:

Interchangeable Attachments: The key feature is its ability to connect to various EXPAND-IT attachments via a coupler device, allowing users to switch between different gardening tasks with a single power unit.
Adjustable Front Handle: The front handle assembly can be adjusted up or down by 180° for user comfort and to help maintain control during operation. It is secured with a wing bolt and washer.
Ergonomic Design: Features a handle overmold for added user comfort.
Operation: To start, press and hold the trigger lock-out, then depress the switch trigger. To stop, release the switch trigger. The trigger lock-out automatically resets to the locked position upon release.
Handling: Users should hold the power head with their right hand on the rear handle and left hand on the front handle, maintaining a firm grip. The power head should be held at a comfortable position, typically with the rear handle about hip height.
Safety Precautions: Always remove the battery pack when assembling, adjusting, cleaning, or storing the tool to prevent accidental starting. Ensure the battery pack is fully seated and latched before operation. Do not operate without an attachment.

Maintenance Features:

Cleaning: The power head should be cleaned of dirt and debris using a damp cloth with a mild detergent after each use. Avoid strong detergents, aromatic oils (pine, lemon), and solvents (kerosene) on plastic parts.
Storage: Remove the battery pack before storing. Store in a dry, well-ventilated place inaccessible to children and away from corrosive agents like garden chemicals or de-icing salts.
Inspection: Periodically inspect for loose, damaged, or missing parts (screws, nuts, bolts, caps). Tighten fasteners and replace damaged parts as needed.
Battery Care: Charge battery packs in locations where the temperature is between 50°F and 100°F. Do not store batteries outside or in vehicles.

RYOBI Brush Cutter Attachment (Model RYBRC77)

Function Description:

The RYOBI Brush Cutter Attachment is designed to be used with the RYOBI 40V Power Head for cutting thicker weeds and pulpy stalks. It utilizes a TRI-ARC® blade for efficient cutting. This attachment is engineered for dependability, ease of operation, and operator safety, providing robust performance for demanding clearing tasks.

Important Technical Specifications:

Blade Cutting Width: 8 inches.
Blade Type: Uses a TRI-ARC® blade (part number 06297), which can be turned over to extend its life but should not be sharpened.
Compatibility: Designed to attach to the RYOBI 40V Power Head via a coupler device.
Safety Features: Requires a brush cutter guard to be firmly secured in place during operation. Includes a gear head locking tool for safe blade installation and removal.
Handle: Requires the use of a "J" handle assembly for optimal control and safety.
Blade Thrust: Users must be aware of blade thrust, a reaction that occurs when the spinning blade contacts an object it cannot cut, potentially causing the unit to thrust away violently.

Usage Features:

Attachment to Power Head: The attachment connects by aligning a button on the attachment shaft with a guide recess on the power head coupler, sliding the shafts together until the button locks into a positioning hole, and then tightening a knob securely.
"J" Handle Installation: The "J" handle is installed on the drive shaft using clamps, a bolt, flat washer, and wing nut. Its position can be adjusted for operator comfort.
Shoulder Harness Installation: A shoulder harness hanger slides over the power head shaft behind the "J" handle and is secured with a bolt, lock washer, and lock nut. The shoulder harness latch connects to this hanger.
Operating Position: The brush cutter should be held with the right hand on the rear handle of the power head and the left hand on the "J" handle. It should be held at a comfortable position, with the trigger handle about hip height. The shoulder harness should be adjusted to position the brush cutter comfortably and minimize blade contact risk.
Cutting Technique: For cutting ease and safety, approach weeds from right to left. The unit is used for cutting in a broad sweeping action from side to side.
Blade Use: Only the TRI-ARC® blade should be used. Do not cut material over 1/2 inch in diameter. Avoid using near sidewalks, fencing, posts, buildings, or other immovable objects.
Safety Precautions: Never attach or adjust the attachment while the power head is running. Always remove the battery pack before making adjustments or maintenance. Wear heavy long pants, long-sleeved shirt, boots, gloves, eye protection, and hearing protection. Keep bystanders at least 50 ft. away. Do not touch or attempt to stop the blade while it is rotating.

Maintenance Features:

Blade Replacement: To remove the blade, align the slot in the flanged washer with the gear head slot, insert the gear head locking tool, and turn the blade nut clockwise (left-handed threads). To install, place the flanged washer over the gear shaft (hollow side toward guard), center the blade, install the cupped washer (raised center away from blade), place the blade nut onto the gear shaft, insert the locking tool, and turn the blade nut counterclockwise (left-handed threads), then torque to 120 in.lb. minimum.
Cleaning: Clean the attachment thoroughly before storing.
Storage: Store in a dry, well-ventilated place inaccessible to children and away from corrosive agents. The hanger cap or secondary hole in the attachment shaft can be used for hanging.
Inspection: Inspect the entire product for damaged, missing, or loose parts before each use. Replace any bent, warped, cracked, chipped, or damaged blades immediately.
