Usage Features:
The blower is designed for ease of use and versatility.
- Assembly: The blower tube (Part B) slides onto the main blower unit (Part A) and locks into place. A safety button (G) allows for easy removal of the blower tube.
- Battery Installation and Removal: The 40V battery aligns with a cavity in the handle housing and locks into place with an audible "click." Removal involves pressing and holding the battery release button (I) while pulling the battery pack out. A strong pull may be required due to the snug fit designed to prevent accidental dislodging.
- Starting and Stopping: The blower is started by squeezing the trigger (J). Releasing the trigger completely stops the blower.
- Variable Speed Control: The trigger (J) allows for variable speed control; squeezing it further increases the speed, and releasing it slightly decreases the speed.
- Cruise Control Lever: The blower is equipped with a cruise control function (K). Once the unit is on, pulling the lever clockwise increases and locks the speed at the desired setting. Pushing the lever counterclockwise decreases the speed. The trigger will be locked at different levels depending on the lever's position.
- Turbo Button: A turbo button (L) provides maximum air speed. Pressing it operates the blower at its highest speed. Releasing the button returns the blower to its previous speed. Note that using the turbo speed significantly reduces runtime.
- Operating Recommendations:
- To prevent scattering, blow around the outer edges of debris piles rather than directly into the center.
- Loosen debris with rakes or brooms before blowing.
- Dampen dusty surfaces with water if available.
- Use blowers to conserve water compared to hoses for lawn and garden tasks.
- Be mindful of children, pets, open windows, or freshly washed cars, and direct debris safely away.
- Always clean up after use and dispose of debris properly.
- Ensure air vents are never covered and remain free of obstructions for proper motor cooling.
Maintenance Features:
Regular maintenance helps ensure the longevity and safe operation of the blower.
- Cleaning:
- Always remove the battery pack before cleaning.
- Use compressed air or a vacuum to clear dust and debris from air vents, ensuring they remain free of obstructions like sawdust and wood chips. Do not spray, wash, or immerse the air vents in water.
- Wipe the housing and plastic components with a moist, soft cloth. Avoid strong solvents or detergents, as they can cause damage or a shock hazard.
- Troubleshooting: The manual provides a troubleshooting guide for common issues:
- Unit will not blow: Possible cause is a blocked tube; corrective action is to clear the blockage.
- Motor fails to start when trigger is depressed: Possible causes include an unsecured battery or an uncharged battery. Corrective actions are to ensure the battery is fully secure and locked into place, and to charge the battery pack according to instructions.
- Unit will not start: Possible cause is a defective power switch; corrective action is to return the unit for repair or call customer service.
The manual emphasizes several safety precautions:
- Always read and understand the owner's manual completely before use.
- Wear eye protection (safety goggles, glasses with side shields, or a full face shield) marked to comply with ANSI Z87.1.
- Keep hair, loose clothing, fingers, and all body parts away from openings and moving parts.
- Do not operate the equipment while barefoot or wearing sandals. Wear protective footwear.
- Keep all bystanders, children, and pets at least 50 ft. (15 m) away from the working area.
- Never allow children under 14 to operate the blower. Children 14 and older must be trained and supervised by a parent.
- Remove the battery pack before making adjustments, changing accessories, storing, or servicing the equipment.
- Recharge only with the specified Kobalt 40-volt charger.
- Do not expose the battery pack or equipment to fire or excessive temperatures above 265°F (130°C).
- Avoid contact with liquid ejected from the battery; if contact occurs, flush with water and seek medical help if it contacts eyes.
- Do not modify or attempt to repair the appliance or battery pack except as indicated in the instructions.
- Operate within the recommended ambient temperature ranges for storage, operation, and charging.
- Be aware of Proposition 65 warnings regarding exposure to chemicals like lead, crystalline silica, arsenic, and chromium from dust created by power tools. Work in well-ventilated areas and use approved safety equipment like dust masks.
