3. PREPARATIONSFOR STARTING
1 Connectthe suction hose.
Use a reinforced-wallor wire braided hose to
prevent suction collapse. Since the pump’s
self-priming time is directly proportional to
-. .
hose length,a short hose is recommended.
[CAUTION]-
Always use a strainer with the suc-
tion hose. Gravel or debris sucked
into the pump will cause serious
damageto the impellerand the pump
casing.
2. Connectthe discharge hose.
When using a fabric hose, always use a hose band to prevent the hose from
disconnecting underhigh pressure.
3. Check the engine oil level.
Engineoil is a majorfactor affectingengine performanceand service life.
Nondetergentor vegetableoils are not recommended.
Useoil classified
“SC” or highergrade.
If the oil levelis belowthe fill levellineon the dipstick, refillwith the properoil (see
table)to edge of the oilfuller neck.
Besureto checkthe oil levelon a levelsurfacewith the engine stopped.

4. Checkthe fuel level.
If level is low, fill to the shoulder of the fuel filter. Use fresh, clean automotive
gasoline.
5. Checkthe primingwater.
It is recommendedthat the water chamber of
pump casing should be primed with full of
water beforeoperating.
[CAUTIONI-l
Never attempt to operate the pump
without priming water or the pump
will overheat. Extended dry opera-
tion will destroy the mechanicalseal.
If the unit has been operated dry,
stop the engine immediately and al-
low the pump to
cool before adding
primingwater.

4. Pull the starter handle slowly until re-
sistance
is felt. This is the "compression"
point. Return the handle to its original
positionand pullswiftly.
Do not pulloutthe rope allthe way.
After starting the engine, allow the

5. OPERATION
1. After starting the engine, gradually open
choke by turning the choke lever and
finally keepit openfully.
Do not fully open the choke lever im-
mediately when the engine is cold or
the ambient temperature is low, be-
causethe engine may stop.
2. After the engine starts, set the speed
control lever at the low speed position
(L)
and warm it up without a load for a few
minutes.
Gradually move the speed control lever to-
ward the high speed position
(H) and set it at
the requiredenginespeed.
NOTE :
Whenever high speed operation is not re-
quired, slow the engine down (idle), by mov-
ing the speed control lever to save fuel and
extendengine life.
