the instruction manual of the power unit.
CAUTION:
Do not operate the machine with-
out installing the hose to the pump attachment.
CAUTION:
When operating the machine, be
sure to fix the hose. The hose may whip due to the
pressure of discharge.
CAUTION:
Adjust the hanger position and
shoulder harness to your comfortable position
before operating.
NOTICE:
Do not pump water containing large
amounts of solids or seawater.
NOTICE:
Do not pump water which exceeds
40°C.

Drain water from the hose after the
operation.
NOTICE:
When moving the machine or changing
the operating position, be sure to turn off the
machine and hold the hose. If you move without
holding the hose, the machine may be damaged.
NOTICE:
After pumping the sewage, pump the
fresh water to wash away the dirt adhering to the
water inlet and inside the hose.
NOTICE:
Do not place the machine on the
ground while it is switched on. Sand or dust may
enter from water inlet and cause a malfunction or
personal injury.
Installing the hose
NOTICE:
When installing or removing the hose,
be careful not to splash water inside the hose on
the operator or the power unit.
Install the hose to the water outlet and fix the hose with
the hose clamp. Tighten the screw of the hose clamp
securely with a screwdriver.

NOTE: The hose that can be installed to the water
outlet is as follows:
• Inner diameter of hose is 25 mm.
• Outer diameter of hose is 33 mm or less.
Pumping operation
Hold the machine firmly with both hands and perform
the pumping operation.
► Fig.11
NOTE: The pumping operation can be started from
the water level of approximately 20 mm, and can be
performed up to the residual water level of approxi-
mately 10 mm.
When using the pump attachment in muddy or sandy
soil, lay down blocks or other materials, and use the
pump attachment on them.

NOTE: Be aware that pumping large amounts of
water which contains fine particles such as sediment
will shorten the life of the pump attachment.
NOTICE:
Do not insert the pump attachment
deeper than the limit mark on the pipe. Doing so
may cause a malfunction of the machine.
