GENERAL POWER TOOL SAFETY WARNINGS

WARNING!
Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mainsoperated (corded) power tool or battery-operated (cordless) power tool.

WORK AREA SAFETY

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

• Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

• Do not expose power tools to rain or wet conditions.
  Water entering a power tool will increase the risk of electric shock.

• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

• When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

• If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.

PERSONAL SAFETY

• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
• Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, nonskid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger  on the switch or energizing power tools that have the switch on invites accidents.
• Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
• Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
• Do not use on a ladder or unstable support. Stable footing on a solid surface enables better control of the power tool in unexpected situations.
• Wear heavy, long pants, long sleeves, boots, and gloves. Do not wear loose fitting clothing, short pants, sandals, or go barefoot. Do not wear jewelry of any kind.

POWER TOOL USE AND CARE

• Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
• Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety  measures reduce the risk of starting the power tool accidentally.
• Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
• Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into  account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

BATTERY TOOL USE AND CARE

• 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.
• Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
• 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.
• 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.
• Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
• Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 265°F may cause explosion.
• Use this product only with batteries and chargers listed in tool/appliance/battery pack/charger correlation supplement 988000-842.
• Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

SERVICE

• Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
• When servicing a power tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance instructions may create a risk of shock or injury.

ADDITIONAL SPECIFIC SAFETY RULES CAN BE FOUND
IN THE APPLICABLE ATTACHMENT’S OPERATOR’S MANUAL

GRASS TRIMMER SAFETY WARNINGS

• Do not use the machine in bad weather conditions, especially when there is a risk of lightning. This decreases the risk of being struck by lightning.
• Thoroughly inspect the area for wildlife where the machine is to be used. Wildlife may be injured by the machine during operation.
• Thoroughly inspect the area where the machine is to be used and remove all stones, sticks, wires, bones, and other foreign objects. Thrown objects can cause personal injury.
• Before using the machine, always visually inspect to see that the cutter or blade and the cutter or blade assembly are not damaged. Damaged parts increase the risk of injury.
• Follow instructions for changing accessories. Improperly tightened blade securing nuts or bolts may either damage the blade or result in it becoming detached.
• Wear eye, ear, head and hand protection. Adequate protective equipment will reduce personal injury by flying debris or accidental contact with the cutting line or blade.
• While operating the machine, always wear non-slip and protective footwear. Do not operate the machine when barefoot or wearing open sandals. This reduces the chance of injury to the feet from contact with the moving cutters or lines.
• While operating the machine, always wear long trousers. Exposed skin increases the likelihood of injury from thrown objects.
• Keep bystanders away while operating the machine. Thrown debris can result in serious personal injury.
• Always use two hands when operating the machine. Holding the machine with both hands will avoid loss of control.
• Hold the machine by the insulated gripping surfaces only, because the cutting line or blade may contact hidden wiring. Cutting line or blades contacting a “live” wire may make exposed metal parts of the machine “live” and could give the operator an electric shock.
• Always keep proper footing and operate the machine only when standing on the ground. Slippery or unstable surfaces may cause a loss of balance or control of the machine.
• Do not operate the machine on excessively steep slopes. This reduces the risk of loss of control, slipping and falling which may result in personal injury.
• When working on slopes, always be sure of your footing, always work across the face of slopes, never up or down and exercise extreme caution when changing direction. This reduces the risk of loss of control, slipping and falling which may result in personal injury.
• Keep all parts of the body away from the cutter, line or blade when the machine is operating. Before you start the machine, make sure the cutter, line or blade is not contacting anything. A moment of inattention while operating the machine may result in injury to yourself or others.
• When cutting brush or saplings that are under tension, be alert for spring back. When the tension in the wood fibers is released, the brush or sapling may strike the operator and/or throw the machine out of control.
• Use extreme caution when cutting brush and saplings. The slender material may catch the blade and be whipped toward you or pull you off balance.
• Do not operate the machine above waist height. This helps prevent unintended cutter or blade contact and enables better control of the machine in unexpected situations.
• Maintain control of the machine and do not touch cutters, lines or blades and other hazardous moving parts while they are still in motion. This reduces the risk of injury from moving parts.
• Carry the machine with the machine switched off and away from your body. Proper handling of the machine will reduce the likelihood of accidental contact with a moving cutter, line or blade.
• Only use replacement cutters, lines, cutting heads and blades specified by the manufacturer. Incorrect replacement parts may increase the risk of breakage and injury.
• When clearing jammed material or servicing the machine, make sure the switch is off and the battery pack is removed. Unexpected starting of the machine while clearing jammed material or servicing may result in serious personal injury.

For complete charging instructions, refer to the Operator’s Manuals for your RYOBI battery pack and charger models.

WARNING:
To avoid serious personal injury, always remove the battery pack and keep hands clear of the trigger lock-out when carrying or transporting the tool.

STARTING/STOPPING THE GRASS TRIMMER
See Figure 10.

To start:

• Select the desired operating speed (HI or LOW).
• Move the trigger lock-out into the slot in the switch trigger.
• Depress the switch trigger.

To stop:

• Release the switch trigger to stop the grass trimmer.
• Upon release of the switch trigger, the trigger lock-out will automatically reset to the locked position.

OPERATING THE GRASS TRIMMER
See Figure 11.
Hold the grass trimmer with your right hand on the rear handle and your left hand on the front handle. Keep a firm grip with both hands while in operation. Grass trimmer should be held at a comfortable position with the rear handle about hip height. Always operate grass trimmer with switch trigger completely depressed. If debris becomes wrapped around the string head, RELEASE THE SWITCH TRIGGER, remove the battery pack, and remove the debris.

WARNING:
Always hold the grass trimmer away from the body keeping clearance between the body and the grass trimmer. Any contact with the cutting head while operating can result in serious personal injury.

WARNING:
Extreme care must be taken when using a blade attachment to ensure safe operation. Read the safety information for safe operation when using a blade attachment and refer to the safety rules and  instructions in your attachment manual. Improper operation could result in serious injury.

CUTTING TIPS
See Figure 12.

• Keep the trimmer tilted toward the area being cut; this is the best cutting area.
• The grass trimmer cuts when passing the unit from right to left. This will avoid throwing debris at the operator. Avoid cutting in the dangerous area shown.
• Use the tip of the line to do the cutting; do not force string head into uncut grass.
• Wire and picket fences cause extra line wear, even breakage. Stone and brick walls, curbs, and wood may wear line rapidly.
• Avoid trees and shrubs. Tree bark, wood moldings, siding, and fence posts can easily be damaged by the line.

ADVANCING THE CUTTING LINE ON THE BUMP FEED TRIMMER HEAD
Line advance is controlled by tapping the string head on grass while running motor at full speed.

• Depress the switch trigger completely.
• Tap the bump knob on ground to advance line. The line advances each time the knob is tapped. Do not hold the knob on the ground.
  NOTE: The line trimming cut-off blade on the grass deflector will cut the line to the correct length.
  NOTE: If the line is worn too short you may not be able to advance the line by tapping it on the ground. If so, remove the battery pack and manually advance the line.

To advance the cutting line manually:

• Remove the battery pack.
• Push the bump knob in while pulling on line(s) to manually advance the line.

ADJUSTING THE LINE CUT-OFF BLADE
See Figures 13 – 14.
This trimmer is equipped with a line cut-off blade on the grass deflector. For best cutting, advance line until it is trimmed to length by the line cut-off blade. Advance line whenever you hear the motor running faster than normal, or when trimming efficiency diminishes. This will maintain best performance and keep line long enough to advance properly. This trimmer is currently set at the 17 in. cutting swath.

To adjust to a cutting swath of 15 in.:

• Remove the battery pack.
• Loosen the blade screw then rotate the line cut-off blade 180°.
• Tighten the blade screw.

WARNING:
The line cut-off blade on the grass deflector is sharp. Use gloves while working with the blade. Direct contact with the blade can result in serious personal injury.

MAINTENANCE

WARNING:
To avoid serious personal injury, always remove the battery pack from the tool when cleaning or performing any maintenance.

WARNING:
Always wear eye protection with side shields marked to comply with ANSI Z87.1, along with hearing protection. Failure to do so could result in objects being thrown into your eyes resulting in possible serious injury.

• Cut one piece of trimmer line 10 ft. long. Insert the line into the eyelet on the string head housing. Push until the end of the line comes out the other side of the housing.

Pull the line until equal amounts of line appear on both sides of the housing.

NOTE: Line may jam if more than 10 ft. is loaded.

• Either by hand or using the SPEED WINDER™, rotate the bump knob clockwise to wind the line on the spool until approximately 6 in. of line is showing on each side.
  NOTE: For best results, after every five to seven revolutions of the SPEED WINDER™, pull both line ends taut for best loading results and to help prevent line from tangling.

• Push the bump knob down while pulling on line(s) to manually advance the line.

When using line in the fixed line/blade housing:

• Remove old line from the string head by pulling one side of the line.
• Fold an 11 in. piece of pre-cut line in half so each half is equal in length.
• Insert the ends of the line through the eyelet in the post and pull tight.
• Repeat wth the other post.

When using blades in the fixed line/blade housing:

• Remove the fixed line/blade housing by rotating the lower housing counterclockwise so the posts and the arrows on the upper housing align, then pull the lower housing away from the upper housing.
• Remove the used blades and discard.
• Install the new blades, making sure they are fully seated.
• Reinstall the fixed line/blade housing as previously described.

CLEARING BUMP FEED TRIMMER HEAD LINE JAM AND/OR REPLACING BUMP KNOB
