9.  
Maintain tools with care. Keep tools clean for better and safer performance. Follow  
instructions for lubricating and changing accessories. Inspect tool cords periodically  
and, if damaged, have them repaired by an authorized technician. The handle must  
be kept clean, dry, and free from oil and grease at all times.  
10. Disconnect power. Unplug tool when not in use.  
11. Avoid unintentional starting. Be sure the Trigger is in the Off position when not in  
use and before plugging in. Do not carry any tool with your finger on the trigger,  
whether it is plugged in or not.  
12. Stay alert. Watch what you are doing, use common sense. Do not operate any tool  
when you are tired.  
13. Check for damaged parts. Before using any tool, any part that appears damaged  
should be carefully checked to determine that it will operate properly and perform its  
intended function. Check for alignment and binding of moving parts; any broken parts  
or mounting fixtures; and any other condition that may affect proper operation. Any  
part that is damaged should be properly repaired or replaced by a qualified  
technician. Do not use the tool if any Trigger does not operate properly.  
14. Guard against electric shock. Prevent body contact with grounded surfaces such as  
pipes, radiators, ranges, and refrigerator enclosures. Use caution near batteries and  
starters.  
15. Replacement parts and accessories. When servicing, use only identical  
replacement parts. Use of any other parts will void the warranty. Only use accessories  
intended for use with this tool. Approved accessories are available from Harbor  
Freight Tools.  
16. Do not operate tool if under the influence of alcohol or drugs. Read warning  
labels if taking prescription medicine to determine if your judgment or reflexes are  
impaired while taking drugs. If there is any doubt, do not operate the tool.  
17. Maintenance. For your safety, service and maintenance should be performed  
regularly by a qualified technician.  
18. People with pacemakers should consult their physician(s) before using this  
product. Electromagnetic fields in close proximity to a heart pacemaker could cause  
interference to or failure of the pacemaker.  
19. Use this tool with both hands. This tool requires the use of both hands when  
operating. This helps maintain tool stability and keeps hands away from the working  
area of the tool.  
20. This unit should only be powered by 12 Volt DC systems.  
Note: Performance of this tool may vary depending on variations in battery power.  
Warning:The warnings, cautions, and instructions discussed in this instruction manual  
cannot cover all possible conditions and situations that may occur. It must be under-  
stood by the operator that common sense and caution are factors which cannot be  
built into this product, but must be supplied by the operator.

Unpacking  
When unpacking, check to make sure the parts listed on page 7 are included. If any parts  
are missing or broken, please call Harbor Freight Tools at the number on the cover of this  
manual as soon as possible.  
Operation  
WARNING! Running engines produce carbon monoxide, an odorless, colorless gas that is  
extremely toxic. Exposure to carbon monoxide can result in headaches, dizziness, vomiting,  
and even death. The engine must only be run in an open, well-ventilated place.  
1.  
Prior to use, be sure that your vehicle or other work object is safely secured in preparation  
for maintenance.  
2.  
3.  
This tool operates on 12 Volts DC. Do not attempt to use this tool with any other voltage.  
You may connect to the 12 Volt power source by directly plugging in the 12 Volt Plug-In  
(24) to the vehicle’s receptacle, or, you may use the Battery Adapter Cable. To use the  
Battery Adapter Cable, simply insert the 12 Volt Plug-In into the Adapter. When it is safe  
to do so, connect the RED clamp to the POSITIVE terminal of a 12 volt battery. Connect  
the BLACK clamp to a clean grounded part of the vehicle such as the engine block or  
frame member. NEVER leave either clamp attached to the vehicle while the impact  
wrench is not being used; disconnect clamps immediately as soon as work is  
finished. Also, make certain that neither clamp can come into contact with any  
other wire or metal portion of the vehicle’s engine. See FIGURE 1.  
NOTE: If the engine is left running while performing this operation, be sure to avoid placing  
any cables or clamps, or your hands, clothes, hair or any other appendage in close proximity  
to the moving parts of the engine.

Operation (continued)  
WARNING: Working around vehicle engines whether running or not is inherently dangerous,  
and extraordinary precautions outside the scope of this booklet are required. Refer to the  
owner’s manual of your vehicle for more information.  
4.  
NOTE: Unlike air-operated or 120V AC impact wrenches, this wrench will build up  
inertia before striking a blow.This is normal,and DOES NOT INDICATE A PROBLEM.  
5.  
Make sure the vehicle is parked safely away from all other moving traffic. Be sure the  
vehicle is parked on a flat, dry, level surface. Be sure the vehicle’s emergency brake is  
set, and the tires have wheel blocks preventing movement.  
6.  
7.  
Select the appropriate size socket to fit the wheel lug nut.Attach the socket to the Impact  
Wrench by pressing them on to the Anvil (4). Only use impact sockets and attachments.  
Position an appropriate lift (not included) under the lift point for each wheel to be re-  
moved. (Follow the vehicle and lift manufacturer’s instructions for doing so.) Lift the  
vehicle until the wheel is off the ground, and support the vehicle securely on jack stands  
(not included).  
8.  
The Impact Wrench is reversible. To operate the Impact Wrench in a forward (tightening)  
direction, set the Directional Lever toward the “R” symbol - see FIGURE 3. To operate  
the Impact Wrench in reverse direction, set the Directional Lever toward the “Lsymbol.  
If the Directional Lever is set in the middle, the unit will not turn in either direction. Using  
the ImpactWrench in reverse, remove the wheel lug nuts according to the manufacturer’s  
recommendations. (In most cases, the manufacturer will recommend that you remove  
the lugs in an alternate pattern, moving around the wheel.)

Operation (continued)  
9.  
Occasionally, you will have to manually break a nut loose before you can remove it with  
the Impact Wrench. To do so, use a Breaker Bar (not included) and Socket to break the  
nut loose. Then, proceed as discussed in number 8 on page 5.  
10. Replace the wheel on the vehicle hub, aligning the wheel studs with the bolt holes in the  
wheel.  
11. Install the wheel lug nuts, following the vehicle manufacturer’s recommendations. To  
avoid cross-threading the lug nuts, thread the nuts on by hand first, before using the  
Impact Wrench.  
CAUTION  
Do not use the Impact Wrench to tighten the lug nuts.  
The torque may exceed the vehicle specifications and damage may result.  
12. When the wheel is securely refastened, use a torque wrench (not included) to check the  
torque on all bolts and ensure that the tightness meets the manufacturer’s recommen-  
dations. Check under the vehicle and remove any tools. Lower the vehicle, disconnect  
the tool and replace the lift and the Impact Wrench to their storage places.  
Maintenance  
1.  
When not in use, store your Impact Wrench and its accessories in its case, in a se-  
cure, dry place. Protect it from water, moisture, oil, fuel, grease or other foreign  
materials which may damage the case, moving parts, or electrical components.  
2.  
3.  
This tool should only be repaired by a qualified technician.  
The 12 Volt Plug-In (24) assembly has a fuse that will eventually need replacing.  
Remove the Cap at the end of the Plug-In and replace the fuse making sure to re-  
place the pieces below, in the exact same order as shown. Only replace the fuse  
with another 12A-250V fuse of the same style.
