Using The Pump; General Usage Instructions - Powerbuilt 648744 Manual De Instrucciones

USING THE PUMP:

The Powerbuilt vacuum pump can be used for a variety of automotive testing and diagnosis tasks. Examples are listed below:
1. Engine mechanical testing, such as testing of engine vacuum, testing intake and exhaust valves, testing manifolds and manifold gaskets for leaks, etc.), air/fuel mixture, cylinder
leakage, turbocharger wastegate, and mechanical and electric vacuum pumps.
2. Testing of vacuum-operated mechanical components, including transmission modulators, heater and air conditioner doors, cruise control modulators, headlight doors, etc.
3. Fuel system testing, such as fuel tank testing, filler cap testing, and testing of fuel lines, pumps, and pressure regulators.
4. Ignition system testing, such as distributor advance mechanisms, spark delay valve testing, vacuum delay valve testing, etc.
5. Emission control system testing, such as EGR valves, PCV valves, ported vacuum switches, thermostatic air cleaners, exhaust heat control or heat riser valves, back pressure
transducer valves, etc.

GENERAL USAGE INSTRUCTIONS:

The Powerbuilt vacuum pump is most often used as a vacuum pump or test instrument. The pump may be connected to a component with the provided vacuum line, connected
directly to the component itself, or connected to an existing vacuum line directly or with the provided tee connector.
To create vacuum:
Move the collar to the rearward position (toward the handles). With the pump connected to the appropriate component or vacuum line, simply squeeze the moveable handle of the
pump with your hand. Continue the squeezing motion until the gauge shows the desired level of vacuum.
To check vacuum:
With the pump connected to the appropriate component or vacuum line, read the measured amount of vacuum at the gauge (engine running). Do NOT pump the handle, as this will
cause an incorrect reading.
RELEASING VACUUM
To release vacuum, slide the collar forward to the release. This allows air to enter the system, relieving the vacuum.
PRESSURE:
Move the collar to the forward position (away from the handles). With the pump connected to the appropriate component, simply squeeze the moveable handle of the pump with
your hand. Continue the squeezing motion until the gauge shows the desired level of pressure.
To check pressure:
With the pump connected to the appropriate component or vacuum line, read the measured amount of pressure at the gauge.
Do NOT pump the handle, as this will cause anincorrect reading.
Releasing pressure:
To release pressure, slide the collar rearward to the release.
Bleeding hydraulic components:
The pump may be used to draw hydraulic fluid through hydraulic lines such as brake and clutch lines. See figure: Bleeding Brakes.
Attach a short piece of clear plastic line to the pump. Using the fluid reservoir with vacuum nipples, attach the other end of the
clear plastic line to one side of the reservoir's cap. Attach a long piece of clear plastic line to the other side of the cap and to the
desired hydraulic fitting for bleeding. With the vacuum pump set to vacuum position, open the hydraulic system's bleeder valve
and slowly draw fluid into the reservoir. Take care not to draw fluid past the reservoir and into the pump.
