CAUTION

Do not scratch, fold, twist, make 

alterations, or bundle the cable, or 

use it as a lifting device. 

The cable 

may be damaged, which may 

cause electrical leakage, short-

circuit, electrical shock, or fire.

Be sure to provide a ground wire 

securely. Do not connect the 

ground wire to a gas pipe, water 

pipe, lightening rod, or telephone 

ground wire. 

Improper grounding 

could cause electrical shock.

Do not use the cabtyre cable, power 

plug, or power outlet if it is damaged 

or it is not closely fitted. Connect 

every conductor of the cabtyre cable 

securely to the terminals. 

Failure to 

observe this can lead to electrical 

shock, short-circuit, or fire.

When transporting or installing the 

pump, bring it with the handle. When 

lifting the product, tie a rope to the 

handle tightly. 

Transporting or 

lifting the pump with its cable 

may damage the cable, which 

may cause electrical leakage, 

electrical shock, or fire.

This pump is neither dust-proof nor 

explosion-proof. Do not use it at a 

dusty place or at a place where 

toxic, corrosive or explosive gas is 

present. 

Use in such places 

could cause fire or explosion.

Prevent a metallic object or dust 

from sticking to the power plug. 

Adhesion of foreign object to the 

plug could cause electrical 

shock, short-circuit, or fire.

If a hose is used for the discharge 

line, take a measure to prevent the 

hose from shaking. 

If the hose 

shakes, you may be wet or 

injured.

 PRECAUTIONS DURING TEST OPERATION AND OPERATION

CAUTION

WARNING

Never start the pump while it is 

suspended, as 

the unit may jerk 

and could lead to injury.

When inspecting the pump, be sure 

to turn off the power supply (earth 

leakage circuit breaker, etc.) so that 

the pump may not start acciden-

tally.

 Failure to do so may lead to 

a serious accident.

Do not operate the product under 

any voltage other than described 

on the nameplate with the voltage 

variation limit within ±10%. If it is 

operated with a generator, it is 

strongly suggested not to operate 

other equipment with the same 

generator. 

Failure to observe this 

caution may cause malfunction 

and breakdown of the product, 

which may lead to electrical 

leakage or electrical shock.

Do not touch the product with bare 

hands during or immediate after 

the operation, as the product may 

become very hot during operation. 

Failure to observe this caution 

may lead to be burned.

Especially, when opening the 

priming plug, pay attention to a 

phenomenon that hot water may 

spout from the pump.

Do not use the product in a liquid 

other than water. 

Use in oil, salt 

water or organic solvents will 

damage it, which may lead to 

electrical leakage or electrical 

shock.

Do not run the product dry or 

operate it with its valve (sluice or 

gate valve) closed, as 

doing so 

will damage the product, which 

may lead to electrical leakage or 

electrical shock.

When operating the pump with its valve 

(sluice or gate valve) closed, it may 

become very hot. 

Be careful not to 

contact the pump accidentally to avoid 

being burned.

When the product will not be used 

for an extended period, be sure to 

turn off the power supply (earth 

leakage circuit breaker, etc.). 

Deterioration of the insulation 

may lead to electrical leakage, 

electrical shock, or fire.

For water 

only

Rated

Voltage

OFF

Do not allow foreign objects (metal 

objects such as pins or wires) to 

enter the suction inlet of the pump. 

Failure to observe this caution 

could cause it to malfunction or 

to operate abnormally, which 

may lead to electrical leakage or 

electrical shock.

Do not use the product for hot or 

warm liquid over 40℃, as 

doing so 

will damage the product, which 

may lead to electrical leakage or 

electrical shock.
