   Use of rubber gloves and substantial footwear
   is recommended when working outdoors. Wear protective hair covering to contain long hair.

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

7. Use the Right Tool – Do not use the tool for any job except that for which it is intended

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

9. Don’t touch moving hazardous parts before the machine is turned off or removed the battery pack and the moving hazardous parts have come to a complete stop.

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

11. Stay Alert – Watch what you are doing. Use common sense. Do not operate the trimmer when you are tired.

12. Do not operate the trimmer while under the influence of alcohol or drugs.

13. Keep guards in place and in working order.

14. Store Trimmer Indoors – When not in use the trimmer should be stored indoors in a dry and high or locked- up place with the battery pack removed – out of reach of children.

15. Maintain Trimmer With Care – Keep the cutting attachment clean for best performance and to reduce the risk of injury. Follow instructions for changing accessories. Keep handles dry, clean, and free from oil and grease.

16. Check Damaged Parts – Before further use of the trimmer, 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.

17. Clear the area to be cut before each use. Remove all objects such as rocks, broken glass, nails, wire, or line that can be thrown or become entangled in the cutting attachment. Make sure that other persons and pets are at least 15m away.

18. Before using the machine and after any impact, check for signs of wear or damage and repair as necessary.

19. Always hold the trimmer firmly, with both hands on the handles while operating. Wrap your fingers and thumbs around the handles.

20. Avoid Accidentally Starting – Don’t carry the trimmer with your finger on the trigger.

21. Do not operate the trimmer in petrolic or explosive atmospheres. Motors in these appliances normally spark, and the sparks might ignite fumes.

22. Damage to Trimmer – If you strike a foreign object with the trimmer or it becomes entangled, stop the tool immediately, remove the battery pack from the line trimmer, check for damage and have any damage repaired before further operation is attempted. Do not operate with a broken guard or spool.

23. If the equipment should start to vibrate abnormally, stop the motor, remove the battery pack from the line trimmer and check immediately for the cause. Vibration is generally a warning of trouble. A loose head may vibrate, crack, break or come off the trimmer, which may result in serious or fatal injury. Make sure that the cutting attachment is properly fixed in position. If the head loosens after fixing it in position, replace it immediately. Never use a trimmer with a loose cutting attachment.

24. Replace a cracked, damaged or worn-out cutting head immediately, even if damage is limited to superficial cracks. Such attachments may shatter at high speed and cause serious or fatal injury.

25. Check the cutting attachment at regular short intervals during operation, or immediately if there is a noticeable change in cutting behavior.

26. Only use Yard Force authorized polymer trimmer line accessories and trimmer line that are designed for use with this machine. Although certain unauthorized attachments might be fitted to the Yard Force line trimmer, their use may be extremely dangerous, and/or damaging to the tools.

27.  To reduce the risk of serious injury, never use wire or metal-reinforced line or other material in place of the nylon cutting lines, also never use the platic blade which are not authorized by the manufacturer. Pieces of wire or plastic parts could break off and be thrown at high speed toward the operator or bystanders.

28. To reduce the risk of injury from loss of control, never work on a ladder or on any other insecure support. Never hold the cutting attachment above waist height.

29. If situations occur that are not covered in this manual, use care and good judgment. Contact the Yard Force Service Center for assistance.

30. Do not charge the battery pack in rain, or in wet locations.

31.  Use only with Yard Force battery packs and chargers.

32. The battery pack must be removed from the appliance before it is scrapped.

33. The battery shall be disposed of safely.

34. Do not dispose of the battery in a fire. The cells may explode. Check with local authorities for possible special disposal instructions.

35. Do not open or mutilate the battery. Released electrolyte is corrosive and may cause damage to the eyes or skin. It may be toxic if swallowed.

36. Exercise care in handling batteries in order not to short the battery with conducting materials such as rings, bracelets, and keys. The battery or conductor may overheat and cause burns.

37. When servicing, use only identical Yard Force replacement parts. Use of any other accessory or attachment may increase the risk of injury.

38. Battery tools do not have to be plugged into an electrical outlet; therefore, they are always in operating condition. Be aware of possible hazards even when the tool is not operating. Take care when performing maintenance or service.

39. Do not wash with a hose; avoid getting water in motor and electrical connections.

40. Save these instructions. Refer to them frequently and use them to instruct others who may use this tool. If you loan this tool to someone else, also loan these instructions to them to prevent misuse of the product and possible injury.

41. Always wear substantial footwear and long trousers while operating the machine.

42. Always be sure of the footing on slopes and to walk, never run.

Tips

1. For best results, do not cut wet grass as it tends to stick to the cutting head and guard, prevents proper discharge of grass trimmings and could cause you to slip and fall.
2. Do not allow the spool cover to drag on the ground or other surfaces.
3. Pay special attention when performing work close to trees and bushes. The cutting head could damage sensitive bark, and damage fence posts.
4. Fold the plant protector out to avoid bringing the cutting device into contact with hard objects such as walls and curbstones.

NOTE: Should you wish to wind the line yourself, the instructions are provided below:
Self-winding, however, is NOT recommended because if the line is not wound properly it can cause the trimmer’s feed system to malfunction or high vibration. For this reason, users are strongly urged to purchase the pre-wound spool.
