NOTE
1. Water cannot be siphoned under the following
conditions:
○ When a hose with an inner diameter of greater than 9
mm is used
○ When there is a height di ff erence of more than 0.5 m
between the water feed inlet and the water surface
○ When the inside of the hose is not su ffi ciently fi lled with
water
2. Set the switch at “ON” without the nozzle attached.
Failure to observe this may result in dry operations,
leading to malfunctions.
3. Set the switch at “OFF” if water does not fl ow out within
two minutes.
Failure to observe this may result in malfunctions (dry
operations.)
The maximum height of suction (lifting range) is
approximately 0.5 m.
Attach this correctly in accordance with conditions.

CAUTION ON LITHIUM-ION BATTERY
To extend the lifetime, the lithium-ion battery equips with the
protection function to stop the output.
In the cases of 1 to 3 described below, when using this
product, even if you are pulling the switch, the motor may
stop. This is not the trouble but the result of protection
function.

battery power may stop.
In this case, stop using the battery and let the battery
cool. After that, you can use it again.
Furthermore, please heed the following warning and caution.
WARNING
In order to prevent any battery leakage, heat generation,
smoke emission, explosion and ignition beforehand, please
be sure to heed the following precautions.
1. Make sure that swarf and dust do not collect on the
battery.

further recharging.
8. Do not put or subject the battery to high temperatures or
high pressure such as into a microwave oven, dryer, or
high pressure container.
9. Keep away from fi re immediately when leakage or foul
odor are detected.
10. Do not use in a location where strong static electricity
generates.
11. If there is battery leakage, foul odor, heat generated,
discolored or deformed, or in any way appears abnormal
during use, recharging or storage, immediately remove it
from the equipment or battery charger, and stop use.
CAUTION
1. If liquid leaking from the battery gets into your eyes,
do not rub your eyes and wash them well with fresh
