Safety Rules

Introduction

This trimmer/edger is designed for regular maintenance trimming of grass and weeds using flexible nylon trimmer line. It is not designed to clear heavy brush or for use with any metal cutting attachments. Any other use other than stated is not recommended. This product has been designed in accordance with the state of the art safety technology of the time. However, even with this technology, it is recognized that residual risk, such as thrown objects, still exist. The operator is directed to closely read, understand, and follow all safety precautions to reduce potential injury from these risks.

Safety Rules

General Power Tool Safety Warnings

WARNING: Read and understand all safety warnings and all instructions.

Failure to follow the warnings and instructions 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 mains-operated (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 (Fig. ). Distractions can cause you to lose control.

CAUTION: Establish a bystander safety

zone of 20 ft (6 m) prior to operation of this equipment. Bystander safety zone is a  ft

( m) circle around the operator that must remain free from bystanders, children, and pets.

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.

• Hold the power tool by insulated gripping

surfaces only, because the trimmer may contact hidden wiring. Power tools

contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

Safety Rules

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, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

• Use personal protective equipment.

Always wear long pants and foot protection.

• 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 (Fig. ). This enables better control of the power tool in unexpected situations.

• Dress properly. Do not wear loose clothing

or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose

clothes, jewelry 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.

• Prolonged use of power tools has been

reported to cause vascular, muscular, or neurological disorders (such as vibration white finger or Raynaud’s syndrome).

To reduce the risk of injury, follow these instructions:

– Wear gloves and keep hands and body

warm.

– Maintain a firm grip on the trimmer/

edger, but do not use prolonged, excessive pressure.

– Take frequent breaks.

The vibration in normal use can differ from the values stated in the “Specifications and Components” table depending on the material being cut, maintenance of the cutting system, and other factors.

Safety Rules

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.

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.

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.

The front handle on the trimmer/edger handle is adjustable. You can move the handle forward or backward along the shaft until it is in a comfortable position for trimming, clearing, or edging.

Loosen the adjustment knob until the front handle slides along the shaft, move the handle to a comfortable position, and then tighten the adjustment knob (Fig. ).

When using the trimmer/edger, grip both the front and rear handles firmly.

Footing

Stand or walk with both feet on solid ground. Do not overreach.

Stopping the Trimmer/Edger

Release the throttle trigger to stop the trimmer/edger.

Starting the Trimmer/Edger

Grasp the front and rear handles firmly. Squeeze the trigger lock-out (), then squeeze the throttle trigger () until the trimmer head moves at the desired speed (Fig. ).

Operating the Trimmer/Edger

Controlling Trimmer Head Speed

The throttle trigger controls the speed at which the trimmer head turns. Squeeze the throttle trigger more firmly for faster cutting speed.

Use the lowest pressure required to cut the material. This helps to maximize the amount of cutting time per battery charge and reduces the number of charging operations required.

Advancing Trimmer Line

The GSL disk lasts longer than typical trimmer lines. However, the trimmer line will wear down over time. Advance the line by bumping the head against the ground to get more line out of the disk.

With the motor running and the trimmer head turning, bump the trimmer head on the ground (Fig. ). More trimmer line comes out of the disk, and excess trimmer line is cut off by the line cutting blade on the bottom of the guard.

If the trimmer line does not come out, the disk may be empty. Turn off the trimmer/edger and replace the disk as described in “Replacing the GSL Disk”.

Trimming

Trimming cuts grass and weeds that are close to walls, fences, and other areas too small to reach with a lawn mower, down to a manageable height but not down to soil level.

Assume proper grip and stance, then start the trimmer. Squeeze the throttle trigger until the trimmer head achieves the minimum speed necessary to cut the grass or weeds.

Angle the trimmer head slightly toward the direction of the cut (Fig. ).

Push the trimmer head slowly from the side into the grass or weeds to be cut, and move the trimmer head back and forth so that the end of the trimmer line contacts the material to be cut.

Do not allow the trimmer line to touch the ground.

Edging

CAUTION: To reduce the risk of injury, keep the guard between the operator and the trimmer head.

Edging maintains an existing border between a lawn and another object such as a sidewalk, pavement, or flower bed. The trimmer/edger is not designed for creating a new hard edge, but is useful for keeping an existing edge clean.

Keep hands away from the throttle trigger, then move the edging guard so that it extends from the trimmer and clicks into place.

Approach the lawn with the trimmer turned so that the bottom of the trimmer head is pointed toward the side of the lawn and the edging guide is pointed toward the ground. Position the edge guide along the edge of the lawn (Fig. ).

In tight spaces, such as against a fence or other barrier, it is acceptable to reverse grip on the rear handle and hold the trimmer/edger in a more vertical position (Fig. ).

For extended periods of edging, it is acceptable to rotate the front handle (Fig. ). This may provide a more comfortable grip.

Maintenance and Cleaning

Trimmer/Edger

WARNING: Failure to identify and replace damaged or worn parts can cause serious personal injury. Inspect the trimmer/edger regularly. Regular inspection is the first step to proper maintenance. Follow the guidelines below to maximize safety and satisfaction. Have any damaged or excessively worn parts replaced immediately.

WARNING: A battery operated tool with the battery pack inserted is always on and can start accidentally. Remove the battery pack from the trimmer/edger before inspecting, cleaning, or performing maintenance.

CAUTION: When cleaning the trimmer/ edger, do not immerse in water or other liquids.

Inspect the Trimmer Head

• Make sure the trimmer head is free of cracks

or other damage. If it is damaged, replace it. Serious personal injury can result if a damaged trimmer head breaks during use.

• Check that the trimmer head rotates freely

and that the trimmer line advances. If the trimmer head fails to rotate freely, see “Correcting Grass Bind”.

• If the trimmer line gets stuck or is tangled,

open the GSL head and check the disk. Replace or reinstall the disk as needed.

• Inspect the grass wrap protector to make

sure t is not cracked, broken, or loose. If it is damaged, replace it.

Inspect the Handles

WARNING: Serious personal injury can result if a damaged handle breaks during use. Make sure that both the front and rear

handles are clean, dry, and are free of cracks or other damage.

Inspect Battery Port

Make sure the battery port is clean, dry, and free of debris. Debris in the battery port can prevent a good electrical connection between the battery pack and the trimmer/edger.

Clean the Trimmer/Edger

• Wipe dust, leaves, and clippings from the

trimmer/edger.

• Clear the air vents to ensure proper airflow

and prevent overheating.

• Remove grass or weeds wound around the

shaft and trimmer head.

• Wipe the trimmer motor housing with a clean

cloth moistened with mild soap and water.

• Never use harsh cleaners or solvents.

IMPORTANT: Keep the vents clear and remove debris wrapped around the trimmer head to help prevent overheating.

Maintenance and Cleaning

Replacing the Gator® Speedload™ (GSL)

The trimmer/edger is equipped with the innovative GSL Cutting System. The GSL head contains a disk of trimmer line that is prewound and self-contained. The GSL disk lasts longer than typical trimmer line. Removing and replacing a disk is simple.

• Pull the head off the base. Pull out the spent disk and discard it (Fig. ).

• Peel two separate pieces of trimmer line from opposite sides of the disk. Make sure each piece is pulled away to create a small gap between the peeled trimmer lines and the disk (Fig. ).

• Place the disk inside the head by lining the disk’s centre hole with the hole in the centre of the head. Press the disk firmly into place (Fig. ).

• Make sure the ends of the trimmer line pieces fit through the two sets of pegs in the head (Fig. ).

• Place GSL head back onto the base and press firmly until it clicks into place.

The innovative tongue-and-groove disk eliminates the need for threading of trimmer line. Disks last longer than traditional trimming lines.

Maintenance and Cleaning

Sharpening the Line Cutting Blade

It is recommended that an Oregon® Service Dealer sharpen the line cutting blade, but it can also be sharpened by the operator.

Line cutting blade sharpening requires a flat file.

After collecting the file, wear gloves and eye protection and remove the battery.

• Lay the trimmer on its side with the line cutting blade on top and face the bottom of the trimmer head (Fig. ).

• Place the file against the cutting edge of the line cutting blade ().

• Push the file down and to the right, removing material from the cutting edge ().

• Repeat until the line cutting blade is sharp.

Correcting Grass Bind

CAUTION: A battery operated tool with the battery pack inserted is always on and can start accidentally. Always remove the battery before correcting grass bind to avoid accidental activation of the trimmer head.

Certain types and lengths of grass can sometimes be caught between the trimmer head and the spindle. When this happens, the grass quickly winds around the shaft clogging the space between the shaft and the trimmer head and slowing or stopping the trimmer head rotation. This condition is called grass bind. The trimmer/edger is equipped with a grass wrap protector shroud between the trimmer head and the spindle to help minimize grass bind, but the condition can still occasionally occur.

To correct grass bind:

• Remove the battery.

• Remove the trimmer head.

• Clean all grass or weeds from the spindle. If

necessary, cut the grass or weeds free.

• Once the spindle is cleared, replace the

trimmer head.
