6. dress properly. Do not wear loose  
clothing or jewelry as they can be  
caught in moving parts. Protective,  
electrically nonconductive clothes  
and nonskid footwear are recom-  
mended when working. Wear restric-  
tive hair covering to contain long hair.  
11. Avoid unintentional firing. Lock  
the Trigger when not in use and  
before plugging in. Do not carry any  
tool with your finger on the Trigger,  
whether it is plugged into an electri-  
cal outlet or not. Do not point the tool  
towards yourself or anyone whether it  
contains staples/nails or not.  
7. do not overreach. Keep proper

using any tool, any part that ap-  
pears damaged should be carefully  
checked to determine that it will oper-  
ate 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 re-  
placed by a qualified technician. Do

metal filings or wood chips. Wear an  
ANSI approved dust mask or respira-  
tor when working around metal,  
wood, and chemical dusts and mists.  
Other people in the work area must  
also wear ANSI-approved impact  
safety goggles.  
9. maintain tools with care. Keep  
tools clean for better and safer per-  
formance. 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. Do  
not operate a tool if any portion of the  
tool’s operating controls are inoper-

21. Hold tool away from head and  
body. During operation the Nailer  
may kick back, causing injury.  
22. avoid working alone. If an accident  
happens, an assistant can bring help.  
16. do not operate tool if under the in-  
fluence of alcohol or drugs. Read  
warning labels if taking prescription  
medicine to determine if your judge-  
ment or reflexes are impaired while  
taking drugs. If there is any doubt, do  
not operate the tool.  
23. take caution, as some woods con-  
tain preservatives such as copper  
chromium arsenate (cca) which  
can be toxic. When nailing these  
materials extra care should be taken  
to avoid inhalation and minimize skin  
contact.  
17. maintenance. The maintenance  
outlined in the “Maintenance” section  
should be performed regularly. For  
your safety, this product should be

State of California) to cause cancer,  
birth defects, or other reproductive  
harm. Some examples of these  
chemicals are:  
18. do not load fasteners with the  
trigger unlocked and/or the tool  
plugged into an electrical outlet.  
Unintentional firing may occur. Al-  
ways assume the tool contains fas-  
teners.  
* Lead from lead-based paints,  
* Crystalline silica from bricks, ce-  
ment, and other masonry products,  
* Arsenic and chromium from chemi-  
cally treated lumber.  
19. Fire fasteners into an appropriate  
work surface only. Do not attempt  
to fire fasteners into surfaces too  
hard to penetrate. Do not drive fas-  
teners on top of other fasteners, or at  
too steep an angle. Nails can rico-  
chet, causing personal injury. Never  
fire the Stapler/Nailer into the air, or  
point it toward yourself or another  
person. Always wear ANSI approved  
impact safety goggles during use,  
maintenance, and reloading.  
(California Health & Safety Code  
25249.5, et seq.)  
25. maintain labels and nameplates on  
the Stapler/Nailer. These carry im-  
portant information. If unreadable or  
missing, contact Harbor Freight Tools  
for a replacement.

WirE cONNEctiON:  
Check with a qualified  
Extension cords  
electrician if you are in doubt  
as to whether the outlet is  
properly grounded. do not  
modify the power cord plug  
provided with the tool. Never  
remove the grounding prong  
from the plug. do not use the  
tool if the power cord or plug  
is damaged. if damaged, have  
it repaired by a service facility  
before use. if the plug will not  
fit the outlet, have a proper  
outlet installed by a qualified  
electrician.  
1. Grounded tools require a three wire  
extension cord. Double Insulated  
tools can use either a two or three  
wire extension cord.  
2. As the distance from the supply outlet  
increases, you must use a heavier  
gauge extension cord. Using exten-  
sion cords with inadequately sized  
wire causes a serious drop in voltage,  
resulting in loss of power and pos-  
sible tool damage.  
(See table a.)  
3. The smaller the gauge number of the  
wire, the greater the capacity of the  
cord. For example, a 14 gauge cord  
can carry a higher current than a 16  
gauge cord. (See table a.)  
double insulated tools: tools  
with two prong plugs  
4. When using more than one exten-  
sion cord to make up the total length,  
make sure each cord contains at  
least the minimum wire size required.  
(See table a.)  
5. If you are using one extension cord  
for more than one tool, add the  
nameplate amperes and use the sum  
to determine the required minimum  
cord size. (See table a.)  
1. Tools marked “Double Insulated” do  
not require grounding. They have  
a special double insulation system  
which satisfies OSHA requirements

6. If you are using an extension cord  
outdoors, make sure it is marked with  
the suffix “W-A” (“W” in Canada) to  
indicate it is acceptable for outdoor  
use.
