Briggs & Stratton 13D1-(19) PPO, 13D1-19 manual Operation − Section C, Priming, Starting

Review all SAFETY information in Section A. Follow the instructions on all tags, labels and decals attached to the pump.

This pump is designed to handle dirty water containing specified entrained solids. Do not attempt to pump volatile, corrosive, or flammable liquids which may damage the pump or endanger per- sonnel as a result of pump failure.

Never tamper with the governor to gain more power. The governor establishes safe operating limits that should not be exceeded. The maximum continuous operating speed for this pump is 4000 RPM.

PRIMING

Install the pump and piping as described in IN- STALLATION. Make sure that the piping connec- tions are tight, and that the pump is securely mounted. Check that the pump is properly lubri- cated (see LUBRICATION in MAINTENANCE AND REPAIR).

This pump is self-priming, but the pump should never be operated unless there is liquid in the pump casing.

Never operate this pump unless there is liquid in the pump casing. The pump will not prime when dry. Extended operation of a dry pump will destroy the seal assembly.

Add liquid to the pump casing when:

1.The pump is being put into service for the first time.

2.The pump has not been used for a consider- able length of time.

3.The liquid in the pump casing has evapo- rated.

Once the pump casing has been filled, the pump will prime and reprime as necessary.

After filling the pump casing, reinstall and tighten the fill plug. Do not attempt to operate the pump unless all connect- ing piping is securely installed. Other- wise, liquid in the pump forced out un- der pressure could cause injury to per- sonnel.

To fill the pump, remove the pump casing fill cover or fill plug in the top of the casing, and add clean liquid until the casing is filled. Replace the fill cover or fill plug before operating the pump.

STARTING

Consult the operations manual furnished with the engine.

OPERATION

Pump speed and operating condition points must be within the continuous per- formance range shown on the curve. (See Section E, Page 1.)

Lines With a Bypass

Close the discharge throttling valve (if so equipped) so that the pump will not have to prime against the weight of the liquid in the discharge
