VACUUM/PRESSURE PUMP AND BRAKE BLEEDING KIT
• Checks vacuum-operated automotive components
• Includes integrated vacuum/pressure gauge
• Includes assorted adapters and hydraulic fluid reservoir
INTRODUCTION:
The Powerbuilt Vacuum/Pressure Pump may be used for many different tasks. Listed below are some examples.
1. Testing vacuum-operated components (door locks, actuators, etc.)
2. Engine mechanical testing (valves, cam timing, head gasket, etc.)
3. Brake and clutch hydraulic system bleeding
4. Measurement of vacuum supplied by boosters, reservoirs, solenoids or the engine.
DESCRIPTION:
The Powerbuilt Vacuum Pump Kit consists of the following items:
• Vacuum Pump Unit
• Fluid Reservoirs (2)
• Fully Sealing Cap for spare Fluid Reservoir (for temporary storage)
• Long Vinyl Hose
• Assorted Small Sections of Vinyl Hose
• Assorted Adapters, Tees, Caps and Suction Cup
The vacuum pump consists of the following parts. See Figure: Legend.
1. Vacuum/Pressure Gauge - A 2 1/2" gauge calibrated in PSI, BAR and inches of mercury.
2. Vacuum Fitting - This barbed fitting is for attachment of the supplied hose. It can also be
directly attached to vehicle vacuum lines or components.
3. Vacuum/Pressure Release Collar - The external collar on the pump slides back and forth on
the pump body. The forward position is for pressure. The rearward position is for vacuum.
Moving the collar from one position to the other position will release stored pressure or vacuum
to the atmosphere.
4. Handles - Comfort grip handles are designed so that they can be easily squeezed together to
create vacuum or pressure.
5. Pump Body - Pump body includes piston, cylinder and valve assembly.

REPLACING PARTS:

When replacing the vacuum gauge or vacuum fitting,it is important to wrap the threads with teflon plumber's tape before threading the pieces together. A good seal must be maintained.
CAUTIONS AND WARNINGS REGARDING USE OF THE VACUUM PUMP
Handling - The Powerbuilt vacuum pump is a precision instrument. Handle it with the same care you would with any other precision tool. Do NOT drop it, handle it roughly,
or otherwise jar the gauge mechanism. Accuracy of the gauge may be affected. Take care not to lay it on hot manifolds or other engine parts. Avoid letting fluids enter the
pump itself. If using as a fluid pump, make sure to use the fluid reservoir included.
Lubrication & Cleaning - The vacuum pump is lubricated with silicone oil at the factory. If you find it necessary to lubricate your pump, use silicone oil or a silicone based
brake fluid (DOT 5). Do NOT use petroleum-based lubricants such as WD-40, motor oil, penetrating oil, etc.). Do NOT uses cleaners such as carburetor cleaner or brake
cleaner sprays in the pump mechanism.
• Can be used to bleed hydraulic systems or siphon fluids
• Special vacuum/pressure release mechanism
