3. PREPARATIONS FOR STARTING
1. Connect the 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 hoseis recommended.
tion hose. Gravel or debris sucked
into the pump will cause serious
2. Connectthe discharge hose.
When using a fabric hose, always use a hose band to prevent the hose from
disconnectingunder high pressure.
3. Checkthe engine oil level.
Engineoil isa major factor affecting engine performanceand service life.
Nondetergentor vegetableoilsare not recommended.
Useoil classified
“SC” or higher grade.
If the oil levelis belowthe fill levelline on the dipstick, refillwith the proper oil (see
table)to edge of the oilfuller neck.

It is recommendedthat the water chamber of
pump
casing should be primed with full of
water beforeoperating.
ICAUTION],
