IMPORTANT SAFETY INSTRUCTIONS

WARNING:
When using electric tools, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and personal injury, including the following:

Read this instruction manual and the charger instruction manual carefully before use.
Clean only with dry cloth.
Do not block any ventilation opening. Install in accordance with the manufacturer’s instruction.
Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
Only use attachments/accessories specified by the manufacturer.
Unplug this apparatus during lighting storms or when unused for long periods of time.
A battery operated radio with integral batteries or a separate battery pack must be recharged only with the specified charger for the battery.
A charger that may be suitable for one type of battery may create a risk of fire when used with another battery.
Use battery operated radio only with specifically designated battery packs. Use of any other batteries may create a risk of 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 sparks, burns, or a fire.
. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded.

CAUTION:
Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type.
Batteries shall not be exposed to excessive heat such as sunshine, fire or the like. For a Portable Sound System, a warning that excessive sound pressure from earphones and headphones can cause hearing loss.

SAVE THESE INSTRUCTIONS.

Important safety instructions for battery cartridge

Before using battery cartridge, read all instructions and cautionary markings on battery charger, battery, and product using battery.

burns and even an explosion.
If electrolyte gets into your eyes, rinse them out with clear water and seek medical attention right away. It may result in loss of
your eyesight.
Do not short the battery cartridge:
(1) Do not touch the terminals with any conductive material.
(2) Avoid storing battery cartridge in a container with other metal objects such as nails, coins, etc.
(3) Do not expose battery cartridge to water or rain. A battery short can cause a large current flow, overheating, possible burns and even a breakdown.
Do not store the tool and battery cartridge in locations where the temperature may reach or exceed 50 °C (122 °F).
Do not incinerate the battery cartridge even if it is severely damaged or is completely worn out. The battery cartridge can explode in a fire.
Be careful not to drop or strike battery.
Do not use a damaged battery.
Follow your local regulations relating to disposal of battery.

Only use genuine Makita batteries. Use of non-genuine Makita batteries, or batteries that have been altered, may result in the battery bursting causing fires, personal injury and damage. It will also void the Makita warranty for the Makita tool and charger.

Tips for maintaining maximum battery life

Charge the battery cartridge before completely discharged. Always stop tool operation and charge the battery cartridge when you notice less tool power.
Never recharge a fully charged battery cartridge. Overcharging shortens the battery service life.
