Be sure to thoroughly read and understand the SAFETY PRECAUTIONS given in this section before using
the equipment in order to operate the equipment correctly.
The precautionary measures described in this section are intended to prevent danger or damage to you or
to others. The contents of this manual that could possibly be performed improperly are classified into two
categories: WARNING, and CAUTION. The categories indicate the extent of possible damage
or the urgency of the precaution. Note however, that what is included under CAUTION may at times
lead to a more serious problem. In either case, the categories pertain to safety-related items, and as such,
must be observed carefully.

Do not operate the product under any conditions other than those for which it is speci-
fied. Failure to observe the precaution can lead to electrical leakage, electrical
shock, fire, water overflow or other problems.

Use an appropriate lifting equip-
ment to lift the unit. Improper
lifting may result in the fall of
the product which could cause
damage of the product or
human injury.
Electrical wiring should be
performed in accordance with all
applicable regulations in your
country. Absolutely provide a
dedicated earth leakage circuit
breaker and a thermal overload
relay suitable for the product
(available on the market). Imper-
fect wiring or improper protective
equipment can lead to electrical
leakage, fire, or explosion in the
worst case.
Use a power outlet that has a sufficient rating and has been exclusively
provided for the pump. If the power outlet is shared with other equipment,
it can lead to an abnormal heat of the outlet and can cause fire as a
result.
Install the product properly in
accordance with this instruction
manual. Improper installation
may result in electrical leakage,
electrical shock, fire, water
leakage, or injury.
Provide a secure grounding
dedicated for the product. Never
fail to provide an earth leakage
circuit breaker and a thermal
overload relay in your starter or
control panel (Both available on
the market). If an electrical
leakage occurs by due to a
product failure, it may cause
electrical shock.

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 electri-
cal 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 the product will be carried by
hand, decide the number of persons
considering the mass of the product.
When lifting up the product, do
not attempt to do it by simply
bowing from the waist. Use the
knees, too, to protect your back.
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.
Install a non-return valve in the
discharge piping if the tank is
deep or it is long, in order to
prevent reverse flow that occurs
when the pump stops. Failure to
do this may allow the reverse
flow, which may result in frequent
ON/Off of the pump. This could cause
breakdown of the pump and may lead to
electrical leakage or electrical shock.

CAUTION
Do not allow foreign object (pin,
wire, etc.) to enter the suction inlet
of the pump. Failure to observe
this caution could cause it to
malfunction or to operate abnor-
mally, which may lead to electri-
cal leakage or electrical shock.

Measuring the operating current
Measuring the insulation resistance
[NOTE] The motor must be inspected if the insulation resistance is considerably lower
than the last inspection.
Inspecting oil
[NOTE] The inspection and replacement of the mechanical seal requires specialized
equipment. To have this operation performed, contact the dealer where this
equipment was purchased, or the Tsurumi sales office in your area.
Overhaul

= within ± 5% of the rated voltage
Measuring the power voltage
To be within the rated current
Insulation resistance reference value = 1MΩminimum
The pump must be overhauled even if the pump appears normal during operation.
Especially, the pump may need to be overhauled earlier if it is used continuously.
Inspection of liffting
chain or rope
Replace if damage, corrosion, or wear has occurred to the chain or rope.
