SAFETY INSTRUCTIONS

PRODUCT SAFETY
WARNING: Some dust created by power sanding, sawing, grinding, drilling and other construction activities contain chemicals known to the state of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints;
• Crystalline silica from bricks and cement and other masonry products;
• Arsenic and chromium from chemically treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work.
To reduce your exposure to this chemical: work in a well-ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to
filter out microscopic particles.

WARNING: This product can expose you to chemicals including lead and Di (2-Ethylhexyl) phthalate (DEHP) which are known to the State of California to cause cancer
and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.

IMPORTANT SAFETY INSTRUCTIONS

WARNING: Read all safety warnings and instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

FOR ALL APPLIANCES

1.  Avoid Dangerous Environment – Don’t use appliances in damp or wet locations.

2.  Don’t Use In Rain.

3.  Keep Children Away – All visitors should be kept at a distance from the work area.

4. Dress Properly – Do not wear loose clothing or jewelry. They can be caught in moving parts.
   Use of rubber gloves and substantial footwear is recommended when working outdoors. Wear protective hair covering to contain long hair.

5. Use Safety Glasses – Always use a face or dust mask if the operation is dusty.

6. Use Right Appliance – Do not use appliances for any job except that for which it is intended.

7. Don’t Force Appliance – It will do the job better and with less likelihood of a risk of injury at the rate for which it was designed.

8. Don’t Overreach – Keep proper footing and balance at all times.

9. Stay alert – Watch what you are doing. Use common sense. Do not operate appliances when you are tired.

10. Store Idle Appliances Indoors – When not in use, appliances should be stored indoors in dry, and high or locked-up place – out of reach of children.

11. Maintain Appliance With Care – Follow instructions for lubricating and changing accessories. Keep handles dry, clean, and free from oil and grease.

12. Check Damaged Parts – Before further use of the appliance, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other condition that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service center unless indicated elsewhere in this manual.

FOR ALL BATTERY–OPERATED GARDENING APPLIANCES

1.  Prevent unintentional starting. Ensure the switch is in the off-position before connecting to the battery pack, picking up or carrying the appliance. Carrying the appliance with your finger on the switch or energizing appliance that has the switch on invites accidents.

2. Disconnect the battery pack from the appliance before making any adjustments, changing accessories, or storing appliances. Such preventive safety measures reduce the risk of starting the appliance accidentally.

3. Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

4. Use appliances only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.

5. When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.

6. Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help.
   Liquid ejected from the battery may cause irritation or burns.

7. Do not use a battery pack or appliance that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.

8. Do not expose a battery pack or appliance to fire or excessive temperature. Exposure to fire or temperature above 130 °C may cause an explosion. Follow all charging instructions and do not charge the battery pack or appliance outside of the temperature range specified in the instructions. Charging improperly or at temperatures outside
   of the specified range may damage the battery and increase the risk of fire.

9. Have servicing performed by a qualified repair person using only identical replacement parts. This will ensure that the safety of the product is maintained.

10. Do not modify or attempt to repair the appliance or the battery pack (as applicable) except as indicated in the instructions for use and care.
