Important Safety Information
WARNING!
READ AND UNDERSTAND
ALL INSTRUCTIONS
Failure to follow instructions listed
below may result in serious injury.
SAVE THESE INSTRUCTIONS
1. Keep bystanders, children, and
visitors away while operating the
Vacuum Pump. Distractions can
cause you to lose control. Protect
others in the work area from injury.
2. Stay alert. Watch what you are
doing, and use common sense
when operating the 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.
3. 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.
4. 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.
5. Use safety equipment.
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.
6. 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.
7. Store idle tools out of reach of
children and other untrained
persons. Tools are dangerous in
the hands of untrained users.
8. 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.
9. 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.
10. 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.

11. Tool service must be performed
only by qualified repair personnel.
Service or maintenance performed
by unqualified personnel could
result in a risk of injury.
12. When servicing a tool, use only
identical replacement parts. Follow
instructions in the Maintenance and
Servicing section of this manual.
Use of unauthorized parts or failure
to follow maintenance instructions
may create a risk of injury.
13. Maintain a safe working environment.
Keep the work area well lit.
Make sure there is adequate
surrounding workspace. Keep the work
area free of obstructions, grease, oil,
trash, and other debris. Do not use
this product in a damp or wet location.
14. Maintain labels and nameplates
on this product. These carry
important information. If unreadable or
missing, contact Harbor Freight Tools
for a replacement.
15. Keep the handle dry, clean, and free
from brake fluid, oil, and grease.
16. Before use read and understand all
warnings, safety precautions, and
instructions as outlined in the vehicle
manufacturer’s service manual.
Every vehicle has specific measurement
values for vacuum related readings.
It is beyond the scope of this manual to
properly describe the correct procedure
and test data for each vehicle.
17. Carbon monoxide is produced while
a vehicle’s engine is operating and
is deadly in a closed environment.
Early signs of carbon monoxide
poisoning resemble the flu, with
headaches, dizziness, or nausea.
If you have these signs, the work
area may not be vented properly.
Get fresh air immediately.
18. Prior to using the Vacuum Pump,
make sure to place the vehicle’s
transmission in “PARK” (if automatic)
or “NEUTRAL” (if manual).
Then, block the tires with chocks.
19. Be alert for hot engine parts
to avoid accidental burns.
20. Avoid accidental fire and/or
explosion. Do not smoke near
engine fuel and battery components.
21. Use the Brake Bleeder only with
brake fluid. Do not attempt to
use the tool to siphon any other
liquids. Damage to the internal
chamber and seal, or future brake
fluid contamination may result.
22. Follow guidelines for proper brake
fluid disposal. Used brake fluid should
be removed from the vehicle and
properly recycled. Many states require
recycling. Contact your local solid/
liquid waste authority for information on
recycling. Do not reuse old brake fluid.
23. Brake fluid may damage paint.
Clean up spilled fluid quickly.
24. The warnings, precautions, and
instructions discussed in this manual
cannot cover all possible conditions
and situations that may occur. The
operator must understand that common
sense and caution are factors which
cannot be built into this product, but
must be supplied by the operator.
