Cordless fan
Hide thumbs


Do not shorten 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.
() 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 0°C (1°F).
Do not incinerate the battery cartridge even if it is severely damaged or is completely worn out. The battery car-
tridge can explode in a fire.
Be careful not to drop or strike battery.
Do not use a damaged battery.
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.
Charge the battery cartridge with room temperature at 10°C – 0°C (0°F – 10°F). Let a hot battery cartridge cool
down before charging it.
Charge the battery cartridge once in every six months if you do not use it for a long period of time.
Cover the battery cover when not use.
Installing or removing of battery cartridge (Fig. F & G)
Always switch off the tool before installing or removing of the battery cartridge.
To remove the battery cartridge, slide it from the tool while sliding the button on the front of the cartridge.
To install the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into
place. Always insert it all the way until it locks in place with a little click. If you can see the red part on the upper side of
the button, it is not locked completely. Install it fully until the red part can not be seen. If not, it may accidentally fall out
of the tool, causing injury to you or someone around you.
Do not use force when installing the battery cartridge. If the cartridge does not slide in easily, it is not being
inserted correctly.
To operate the cordless fan using battery cartridge, please refer to the instruction of battery charger.
Timer setting
The cordless fan can set a run time for 1 hour,  hours, or  hours by the timer switch ( in Fig. A-1).
The number underneath the LED shows the remaining hour for turn off.
The cordless fan may run less time than the time you set when you use the battery cartridge.
In order to prolong the battery life, the cordless fan has automatic stop output function. If the battery capacity is not
enough, the fan will stop working; this is because of the cordlessfan's self-protect function, rather than breakdown.
Then you need to take out the battery and charge it.
When servicing, ask Makita authorized service centers and with only identical replacement parts. Use of any other
parts may create a hazard or cause product damage.
To avoid serious personal injury, always remove the AC adaptor or battery cartridge from the unit when cleaning or
performing any maintenance.
Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of com-
mercial solvents and may be damaged by their use. After the portable fan cooled, use clean clothes to remove dirt,
dust, oil, grease etc.
Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils etc., contact with plastic
parts. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury.
All parts should be replaced at an Authorized Service Center.
To prevent fire or burning, allow the oscillating fan to cool down completely before you store it.
Do not store the discharged battery for long periods, as it can shorten its service life.
