Read 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.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
2) Electrical safety
a) 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.
b) 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.
c) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
d) 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.
e) 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.
f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply.
Use of an RCD reduces the risk of electric shock.
3) Personal safety
a) 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.
b) 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.
c) 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 energising power tools that have the switch on invites accidents.
d) 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.
e) Do not overreach. Keep proper footing and balance at all times.
This enables better control of the power tool in unexpected situations.
f) 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.

Use of dust collection can reduce dust related hazards.
4) Power tool use and care
a) 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.
b) 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.
c) 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.
d) 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.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools' operation.
If damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
g) 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.
5) Battery tool use and care
a) 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.
b) Use power tools only with specifically designated battery packs.
Use of any other battery packs may create a risk of injury and fire.
c) 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.

(2) Regarding the temperatures of the rechargeable battery
The temperatures for rechargeable batteries are as shown in the Table 2, and batteries that have become hot should be cooled for a while before being recharged.
Table 2 Recharging ranges of batteries
| Temperatures at which the battery can be recharged |
| 0°C – 50°C |
(3) Regarding recharging time
Table 3 shows the recharging time required according to the type of battery.
Table 3 Charging time (At 20^ C )
| Charger Battery | UC18Y GSL UC | 18YRSL |
| BSL1430 Approx. | 90 min. Approx. 45 | min. |
| BSL1830 Approx. | 90 min. Approx. 45 | min. |
NOTE
The recharging time may vary according to the ambient temperature.
4. Disconnect the charger's power cord from the receptacle.
5. Hold the charger firmly and pull out the battery.
NOTE
Be sure to pull out the battery from the charger after use, and then keep it.
Regarding electric discharge in case of new batteries, etc.
As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the first and second time. This is a temporary phenomenon, and normal time required for recharging will be restored by recharging the batteries 2-3 times.
How to make the batteries perform longer
(1) Recharge the batteries before they become completely exhausted.
When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.
CAUTION
If the battery is charged while it is heated because it has been left for a long time in a location subject to direct sunlight or because the battery has just been used, the pilot lamp of the charger lights for 1 second, does not light for 0.5 seconds (off for 0.5 seconds). In such a case, first let the battery cool, then start charging.
- When the pilot lamp flickers (at 0.2-second intervals), check for and take out any foreign objects in the charger's battery connector. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your Center.
Since the built-in micro computer takes about 3 seconds to confirm that the battery being charged with UC18YGSL is taken out, wait for a minimum of 3 seconds before reinserting it to continue charging. If the battery is reinserted within 3 seconds, the battery may not be properly charged.
ABOUT POWER LAMP
The power lamp indicates various statuses for the tool. (Fig. 7)
Table 4 shows the various statuses indicated by the power lamp.

OPERATIONAL CAUTIONS
Continuous work
This tool comes with an over-heat protection circuit that protects the electronic parts that control the rechargeable battery. In continuous trimming work, tool temperature will rise and eventually trigger the overheat protection circuit, which will shut down the tool.
If this happens, let the tool cool for a length of time. When the temperature drops, it will again become possible to use the tool. When the rechargeable battery has to be exchanged during continuous operation, let the tool rest for about 15 minutes.
Overload Protection
This tool comes with an overload p to protect the electronic parts controlling the tool. In continuous overload during trimming work (locking the nylon head, etc.), the overload protection circuit shuts down the motor. If this happens, turn OFF the power, and then resolve the problem causing the overload. The power lamp blinks if the lever is pressed after the motor has stopped (see page 16, "ABOUT POWER LAMP"). The power automatically turns OFF if the power lamp blinks longer than 5 seconds. If this happens, resolve the problem causing the overload, and then switch the power button ON to resume using the tool.
MAINTENANCE AND INSPECTION
CAUTION
Pull out battery before doing any inspection or maintenance.
1. Checking the condition of the nylon head
The nylon head should be checked regularly. If worn or broken nylon head can slip or decrease the efficiency of the motor and burn it out.
Replace worn nylon head with new ones.
CAUTION
If you use a nylon head of which point is worn or broken, it will be dangerous. So replace it with a new one.
2. Check the Screws
Loose screws are dangerous. Regularly inspect them and make sure they are tight.
CAUTION
Using this power tool with loosened screws is extremely dangerous.
3. Inspecting the carbon brushes (Fig. 28)
The motor employs carbon brushes which are consumable parts. Since and excessively worn carbon brush can result in motor trouble, replace the carbon brush with new ones when it becomes worn to or near the "wear limit". In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.
NOTE
When replacing the carbon brush with a new one, be sure to use the Hitachi Carbon Brush Code No. 999015.
4. Replacing carbon brushes
Take out the carbon brush by first removing the brush cap and then hooking the protrusion of the carbon brush with a slotted head screw driver, etc., as shown in Fig. 29.
When installing the carbon brush, choose the direction so that the nail of the carbon brush (see Fig. 30) agrees with the contact portion of brush tube. Then push it in with a finger as illustrated in Fig. 31. Lastly, install the brush cap.
CAUTION
Be absolutely sure to insert the nail of the carbon brush into the contact portion of brush tube. (You can insert whichever one of the two nails provided.)
Caution must be exercised since any error in this operation can result in the deformed nail of the carbon brush and may cause motor trouble at an early stage.
5. Cleaning of the outside
When the grass trimmer is stained, wipe with a soft dry cloth or a cloth moistened with soapy water. Do not use chloric solvents, gasoline or paint thinner, as they melt plastics.
6. Storage
