4-stroke engine
4-stroke engine needs "engine oil" There is no engine oil in the engine.
Before starting engine, engine oil must be filled. If you start engine without engine oil,

DISSAEMBLY AND CLEANING ( Parts replacement )
1. Turn the knob counterclock-wise and remove the knob.
2. Pull the handle towards you, and then both front cover
and volute casing can be removed.
3. Remove the peripheral plug before taking impeller out.
The impeller can be detached by giving it a shock
with a rod or the like.
4. Draw out the mechanichal seal from the engine shaft
along with the sleeve.
NOTE: Please do not hammer an impeller directly when you want to take it out from
the machine. It might damage the impeller.
Instead, take out the plug set first and then insert something like a stick which
is thin enough to get through the hole and hammer the stick at the other end.
The impeller can be removed out easily without damaging it.
NOTE: When assembling the parts, do not forget to place the adjusting washer,
O-ring, etc., in the right positions. Also, correctly install the front cover
and evenly tighten the right and left knobs.
Note that incomplete assembling may affect the performance of the unit.

ATTENTION AFTER USE
1 Drain water after use
After use, remove the drain plug at the bottom and pour water
from the suction/discharge ports so that the remaining sand
is forced out of the pump. If the pump is used to transfer
muddy water over a long period of time, a large volume of
sand will be piled up in the pump casing, making it difficult to remove
