PERSONAL SAFETY
1. Stay alert. Watch what you are doing, and use common sense when operating the Brake Bleeder/Vacuum Pump. Do not use the tool while tired or under
the influence of drugs, alcohol, or medication. A moment of inattention while
operating the tool may result in serious personal injury.
2. Dress properly. Do not wear loose clothing or jewelry. Contain long hair.
Keep your hair, clothing, and jewelry away from moving parts. Loose clothes,
jewelry, or long hair can be caught in moving parts.
3. Do not overreach. Keep proper footing and balance at all times. Proper footing
and balance enables better control of the power tool in unexpected situations.
4. Use safety equipment. Always wear ANSI approved safety glasses underneath a
full face safety shield. Nonskid safety shoes, hard hat, or hearing protection must
be used for appropriate conditions.
TOOL USE AND CARE
1. Do not force the tool. Use the correct tool for your application. The correct tool
will do the job better and safer at the rate for which it is designed.
2. Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
3. Maintain tools with care. Keep tools dry and clean. Properly maintained tools
are less likely to bind and are easier to control. Do not use a damaged tool. Tag
damaged tools “Do not use” until repaired.
4. Check for misalignment or binding of moving parts, breakage of parts, and
any other condition that may affect the tool’s operation. If damaged, have the
tool serviced before using. Many accidents are caused by poorly maintained
tools.
5. Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for one tool may become hazardous
when used on another tool.
SERVICE
1. Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
2. When servicing a tool, use only identical replacement parts. Follow instruc-
tions in the
Use of unauthorized parts or failure to follow maintenance instructions may create
a risk of injury.

ASSEMBLY AND OPERATING INSTRUCTIONS
To Bleed Brakes:
1. Attach a 3” Vacuum Hose (5) to the bottom of the Jar Lid (2a). (See Figure A.)
2. Attach a 23” Vacuum Hose (4) to the top of the Jar Lid (2a) marked “TO PUMP”.
Then, attach the other end of the 23” Vacuum Hose to the Brake Bleeder/Vacuum
Pump (1). (See Figure A.)
3. Firmly attach the Jar Lid (2a) to the Reservoir Jar (3). (See Figure A.)
4. Remove the cap from the vehicle’s master cylinder, and check to make sure the

master cylinder is full of brake fluid. If not full, fill the master cylinder to capacity with
clean, new brake fluid. (Use only the kind of brake fluid recommended by the vehicle manufacturer.)
6. NOTE: Determine the proper brake bleeding sequence from your vehicle service
manual (i.e., right rear wheel, left rear wheel, right front wheel, left front wheel).
7. Connect the 23” Vacuum Hose (4) to the remaining port on the Jar Lid (2a) and then
connect the other end to the Brake Bleeder Screw Adapter (9). (See Figure A.)
8. Squeeze the Handle of the Brake Bleeder/Vacuum Pump (1) 10 to 15 times to
create a vacuum in its Reservoir Jar (3). NOTE: The Gauge on the Brake Bleeder/
Vacuum Pump should read at approximately 10 in/Hg. Do not exceed 20 in/Hg. A
greater vacuum could damage the vehicle’s brake system. (See Figure A.)
9. Once the Brake Bleeder/Vacuum Pump (1) is ready, check for leaks at the Reservoir Jar (3) and at all Vacuum Hose (4, 5) connections. If there is a leak, release the
vacuum in the Brake Bleeder/Vacuum Pump with the Vacuum Release Control.
CAUTION! NEVER remove the Jar Lid (2a) before releasing the vacuum
in the Brake Bleeder/Vacuum Pump.
Correct the leak, and once again create a vacuum in the Brake Bleeder/Vacuum
Pump to approximately 10 in/Hg. (See Figure A.)
10. Open the vehicle’s wheel caliper bleeder screw, and allow brake fluid to flow into the
Reservoir Jar (3). Then, retighten the wheel caliper bleeder screw after bleeding.
(See Figure A.)
11. Release the vacuum in the Brake Bleeder/Vacuum Pump (1) with the Vacuum Release Control. Then, disconnect the Brake Bleeder Screw Adapter (9) from the
vehicle’s wheel caliper bleeder screw. (See Figure A.)
12. NOTE: When necessary, release the vacuum in the tool and empty its Reservoir
Jar (3) of old brake fluid. To assist in transport, this set includes a leak-resistant Lid
(2b) without hose connections. After the brake fluid is disposed of properly, resume
bleeding the brakes.
13. Remove the cap from the vehicle’s master cylinder, and refill the master cylinder
back to its normal capacity with clean, new brake fluid. Then, replace the cap on
the master cylinder.
14. Proceed to the vehicle’s next wheel, and perform the same steps as above.

15. When finished using the Brake Bleeder/Vacuum Pump, clean the tool and store it in
a clean, dry location out of reach of children.
16. WARNING! Before driving the vehicle, carefully check for leaks and
test for proper brake operation.
INSPECTION, MAINTENANCE, AND CLEANING
1. WARNING! Always release the vacuum in the Brake Bleeder/Vacuum
Pump before performing any inspection, maintenance, or cleaning.
2. Before each use: Inspect the general condition of the Brake Bleeder/Vacuum
Pump. Check for misalignment or binding of moving parts, cracked or broken
parts, damaged Hoses, loose connections, and any other condition that may
affect its safe operation. If a problem occurs, have the problem corrected before
further use. Do not use damaged equipment.
3. When cleaning: Do not clean the Brake Bleeder/Vacuum Pump with cleaners or
other solvents not intended for use with plastic components. Use a clean cloth
and, if necessary, a mild detergent. Do not immerse the Brake Bleeder/Vacuum
Pump (1) component in any liquid.
4. When storing: Never store fluid in the Reservoir Jar (3) of the Brake Bleeder/
Vacuum Pump. Always dispose of excess fluid properly, according to federal,
state, and local guidelines. Always store the Brake Bleeder/Vacuum Pump in a
clean, dry location out of reach of children.
5. WARNING! All maintenance, service, or repairs not listed in this
manual are only to be attempted by a qualified service technician.
