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.

Before checking or refilling engine oil, be sure the engine is
located on stable, level surface and stopped.
Do not screw the oil gauge into the oil filler neck to check
oil level. If the oil level is low, refill to the upper level with
the following recommended oil.
Use 4-stroke automotive detergent oil of API service
class SF or higher grade.
Select the viscosity based on the air temperature at the
time of operation as shown in the table. (See Fig.2

It is recommended that the water chamber of pump casing
should be primed with full of water before operating.
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.

q)
(2) Set the stop switch to the position “ON”. (See Fig.3
-
w)
(3) Close the choke lever. (See Fig.3
-
e)
If the engine is cold or the ambient temperature is low,
close the choke lever fully.
If the engine is warm or the ambient temperature is high,
open the choke lever half-way, or keep it fully open.
(4) Push the primer pump 7 to 10 times to feed the fuel to
the carburetor. (See Fig.3

(5) Pull the starter handle slowly until resistance is felt. This
is the “compression” point. Return the handle to its
original position and pull swiftly.
Do not pull out the rope all the way.
After starting the engine, allow the starter handle to return
to its original position while still holding the handle.
(See Fig.3

(6) After starting the engine, gradually open choke by turning
the choke lever and finally keep it fully opened. Do not
fully open the choke lever immediately when the engine
is cold or the ambient temperature is low, because the
engine may stop. (See Fig.3

(1) After the engine starts, set the speed control lever at the
low speed position (L) and warm it up without load for a
few minutes. (See Fig.4
q)
(2) Gradually move the speed control lever toward the high
speed position (H) and set it at the required engine speed.
(See Fig.4
w)
Whenever high speed operation is not required, slow the
engine down (idle) by moving the speed control lever to
save fuel and extend engine life.
NOTE
If the engine is operated at upside down, white smoke may
be exhausted from the muffler.
