Preparation Before Operation
(See Figure 2)
Symbols
This safety alert symbol indicates that this
message involves personal safety. Words
danger, warning and caution indicated de‐
gree of hazard. Death, personal injury and/‐
or property damage may occur unless in‐
structions are followed carefully.
You are not ready to operate this engine if
you have not read and understood the fol‐
lowing safety items. Read this entire owner/‐
operator manual and the operating instruc‐
tions of the equipment this engine powers.
Note: Engines and transmissions are shipped with oil.
Check oil level before operating.
1.
Inspect the unit carefully for damage resulting from
shipment. Abusive handling during shipment resulting
in obvious damage to the engine or the pump may
cause rubbing of moving parts resulting in severe en‐
gine or pump damage if operation is attempted.
2.
Check the unit for bolts or other fasteners which may
have vibrated loose during shipment.
3.
These units are equipped to use a type 12N14-3A
``motorcycle” battery.
Battery Specifications:
•
Capacity - 14 Amp Hour
•
Approximately 130 cold cranking amps
•
Size: 3-1/2 x 5-1/4 x 6-1/2 tall
4.
Prepare the engine for starting by reading completely
and following the Briggs and Stratton Operation and
Maintenance Instructions.
5.
Fill engine with oil per Briggs & Stratton instructions.
The PB18 Series Portable Pumps use Briggs & Strat‐
ton Model 350477 Series engines.
6.
Fill fuel tank. Use clean, fresh, lead-free gasoline with
a minimum of 85 octane. (See Briggs & Stratton in‐
structions for more detail.) The engine should be re‐
fueled prior to use to avoid the need to refuel when it
is hot.
7.
Fill transmission with 1 pint of SAE 90W oil through
top plug or breather elbow. Remove oil level plug to
check oil level (gear driven pump only).
8.
With the ignition switch OFF, rotate the engine crank‐
shaft several times with the rewind start rope to make
sure the engine and pump turn over freely with no
abnormal rubbing noises.
WARNING
!
Low oil. May result in engine power loss, personal
injury or property damage.
Maintain correct oil level. Check oil level each time
engine is refueled. Low oil level may cause loss of
engine power and may result in personal injury or
property damage.
Connections between the pump and intake and discharge
hoses or piping should be made leakproof. Wrench torque
should be limited to 80 ft. lb. maximum when making con‐
nections. If more than 80 ft. lb. torque is required, use two
wrenches, one wrench on the pump intake or discharge
fitting and one wrench on the hose or pipe being attached.
Balancing the torque applied between the two wrenches
will avoid excessive forces to the pumping unit.
When pumping units are permanently mounted in an ap‐
paratus and attached to rigid piping, connections between
the pump and the piping should be made using flexible
couplings to avoid applying excessive forces to the pump.
Starting the Engine
(See Figure 3)
1.
Refer to the Briggs & Stratton Operation & Mainte‐
nance Instructions.
2.
Move the choke control lever to the “CHOKE” posi‐
tion.
3.
Move the throttle control to the “FAST” position.
4.
Rotate ignition switch to the “RUN” position.
5.
Rotate and hold the ignition switch in the “START”
position to operate the starter motor relay and start
engine. (Alternate: Use manual rope start.)
6.
After the engine starts, return the ignition switch to the
“RUN” position, return the choke control to the “RUN”
position and adjust the throttle as required.
Priming the Pump
The PB18 Series utilize an exhaust primer.
1.
Connect intake and discharge hoses or piping.
2.
Close the discharge valve if so equipped.
3.
Start engine and advance the throttle to “FAST” posi‐
tion.
4.
Pull the priming knob located at the top of the engine
to “PRIME” position.
Alternate:
Pull the primer lever and advance the
throttle.
5.
Operate primer until water is ejected from it.
