1. ATTACH THE FLANGE
AND CHECK VALVES
(PTG208D, 307D)
Attach the suction flange, delivery flange and check valves to
the pump when operating the brand new pump for the first time.
Be careful not to overtighten the bolts.
Suction flange tightening torque : 90-120 kg-cm
Delivery flange tightening torque : 90-120 kg-cm

Use a reinforced-wall or wire braided hose to prevent suction
collapse.
Since the pump self-priming time is directly proportional to
hose length, a short hose is recommended.
Always use a strainer with the suction hose. Gravel
or debris sucked into the pump will cause serious
damage to the impeller and the pump casting.

For break-in of a new engine.
Use mixture fuel of gasoline 15 to 20 : 2-cycle
engine oil 1 during first 20 hours of operation.
CAUTION
Never attempt to operate the pump without priming
water or the pump will overheat. Extended dry
operation will destroy the mechanical seal.
If the unit has been operated dry, stop the engine
immediately and allow the pump to cool before
adding priming water.
WARNING
Do not refuel while smoking, near an open flame
or other such potential fire hazards. Otherwise
fire accident may occur.
