SAFETY WARNINGS

Cordless vacuum cleaner safety warnings
WARNING: IMPORTANT! READ CAREFULLY
all safety warnings and all instructions BEFORE USE. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Before use, make sure that this cleaner must be used by people who have been adequately instructed on the use of this cleaner.
Do not use the cleaner without the filter. Replace a damaged filter immediately.
Do not attempt to pick up flammable materials, fireworks, lighted cigarettes, hot ashes, hot metal chips, sharp materials such as razors, needles, broken glass or the like.
NEVER USE THE CLEANER IN THE VICINITY OF GASOLINE, GAS, PAINT, ADHESIVES OR OTHER HIGHLY EXPLOSIVE SUBSTANCES. The switch emits sparks when turned ON and OFF. And so does the motor commutator during operation. A dangerous explosion may result.
This cleaner is not suitable for picking up hazardous dust.
Never vacuum up toxic, carcinogenic, combustible or other hazardous materials such as asbestos, arsenic, barium, beryllium, lead, pesticides, or other health endangering materials.
Never use the cleaner outdoors in the rain.
For Finland, this machine is not to be used outdoors at low temperature.
Do not use close to heat sources (stoves, etc.).
Do not block cooling vents. These vents permit cooling of the motor. Blockage should be carefully avoided otherwise the motor will burn out from lack of ventilation.
Keep proper footing and balance at all times.
Do not fold, tug or step on the hose.
Stop the cleaner immediately if you notice poor performance or anything abnormal during operation.
DISCONNECT THE BATTERIES. When not in use, before servicing, and when changing accessories.
Clean and service the cleaner immediately after each use to keep it in tiptop operating condition.
MAINTAIN THE CLEANER WITH CARE. Keep the cleaner clean for better and safer performance. Follow instructions for changing accessories. Keep handles dry, clean, and free from oil and grease.
CHECK DAMAGED PARTS. Before further use of the cleaner, 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 conditions 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 otherwise indicated elsewhere in this instruction manual. Have defective switches replaced by authorized service center. Don’t use the cleaner if switch does not turn it on and off.
REPLACEMENT PARTS. When servicing, use only identical replacement parts.
When not in use, always store the cleaner indoors.
Be kind to your cleaner. Rough handling can cause breakage of even the most sturdily built cleaner.
Do not attempt to clean the exterior or interior with benzine, thinner or cleaning chemicals. Cracks and discoloration may be caused.
Do not use cleaner in an enclosed space whereflammable, explosive or toxic vapors are given off by oil-base paint, paint-thinner, gasoline, some mothproofing substances, etc., or in areas where flammable dust is present.
Do not operate the cleaner while under the influence of drugs or alcohol.
As a basic rule of safety, use safety goggles or safety glasses with side shields.
Use a dust mask in dusty work conditions.
This machine is not intended for use by persons including children with reduced physical, sensory or mental capabilities, or lack of experience and knowledge.
Children should be supervised to ensure that they do not play with the cleaner.
Never handle battery(ies) and cleaner with wet hands.
Use extreme caution when cleaning on stairs.
Do not use the cleaner as a stool or work bench. The machine may fall down and may result in personal injury.

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 130 °C may cause explosion.
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.
Do not use a corded power supply such as battery adapter or portable power pack with this tool. The cable of such power supply may hinder the operation and result in personal injury.

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.
Follow instruction for lubricating and changing accessories.
Keep handles dry, clean and free from oil and grease.

Important safety instructions for battery cartridge

Do not use a damaged battery.
The contained lithium-ion batteries are subject to the Dangerous Goods Legislation requirements. For commercial transports e.g. by third parties, forwarding agents, special requirement on packaging and labeling must be observed. For preparation of the item being shipped, consulting an expert for hazardous material is required. Please also observe possibly more detailed national regulations. Tape or mask off open contacts and pack up the battery in such a manner that it cannot move around in the packaging.
When disposing the battery cartridge, remove it from the tool and dispose of it in a safe place. Follow your local regulations relating to disposal of battery.
Use the batteries only with the products specified by Makita. Installing the batteries to non-compliant products may result in a fire, excessive heat, explosion, or leak of electrolyte.
If the tool is not used for a long period of time, the battery must be removed from the tool.
During and after use, the battery cartridge may take on heat which can cause burns or low temperature burns. Pay attention to the handling of hot battery cartridges.
Do not touch the terminal of the tool immediately after use as it may get hot enough to cause burns.
Do not allow chips, dust, or soil stuck into the terminals, holes, and grooves of the battery cartridge. It may result in poor performance or breakdown of the tool or battery cartridge.
Unless the tool supports the use near high-voltage electrical power lines, do not use the battery cartridge near high-voltage electrical power lines. It may result in a malfunction or breakdown of the tool or battery cartridge. 18. Keep the battery away from children.
