Conductor size should be in accor-  
dance with the chart below. The  
amperage rating should be listed on  
the motor or tool nameplate. An  
undersized cord will cause a drop in  
line voltage resulting in loss of power  
and overheating. Your extension  
cord must also contain a ground wire  
and plug pin. Always repair or  
replace extension cords if they  
become damaged.  
Keep tools sharp and clean for best

OPERATIONS  
Before You Begin  
Inspect angle grinder before use. The  
grinding wheel must be free of cracks,  
chips and breaks. If there are any signs of  
damage, discard the grinding wheel and  
replace immediately.  
The Model G9911 was specifically  
designed for cutting, grinding and  
polishing. Do not modify and/or use  
this machine for any other purpose.  
Modifications or improper use of  
this tool will void the warranty. If you  
are confused about any aspect of  
this machine, DO NOT use it until  
you have answered all your ques-  
tions. Serious personal injury may  
occur.  
Using Your Tool  
Use extreme caution when operating this  
tool. Always be aware of your surrounding  
working area. Be sure to wear appropriate  
eye protection and be sure to work at a  
safe distance from others in the area.  
Be sure to use the appropriate abrasive  
and cutting wheels with this grinder. Use  
only specified grinding wheels. The wheels  
used by this grinder must be reinforced  
fiber resin, with a safety linear velocity not  
lower than 6,200 RPM.  
Operating this equipment has the  
potential for flying debris to cause eye  
injury. Always wear safety glasses or  
goggles when operating equipment.  
Everyday glasses or reading glasses  
only have impact resistant lenses, they  
are not safety glasses. Be certain the  
safety glasses you wear meet the  
appropriate standards of the American  
National Standards Institute (ANSI).  
Damaged wheels can break under normal  
use, creating a dangerous situation that  
could cause serious injury. If the integrity  
of a wheel is in question, always replace  
with a new one.  
Do not apply excessive pressure to the  
grinder while cutting, as breakage of the  
wheel could occur. If the grinder begins to  
stall, decrease pressure immediately. If the  
wheel stops abruptly, turn the grinder off  
immediately.  
Always use wheel guard. The wheel guard  
is an important part of the grinder. Do not  
operate the grinder if the wheel guard has  
been removed. Do not modify the wheel  
guard or make the opening more than  
180°.

MAINTENANCE  
Maintenance  
Keeping Tools Clean  
Your G9911 will give you years of trouble  
free service if you keep it clean and free of  
built-up dust or grime. Ensure that no air  
passages get blocked. If they do, blow  
them out with compressed air. WARNING:  
Wear safety glasses when cleaning tool  
with compressed air.  
Regular periodic maintenance on your  
G9911 will ensure its optimum perfor-  
mance. Make a habit of inspecting your

following conditions and repair or replace  
when necessary:  
1.  
2.  
3.  
4.  
Loose fasteners.  
Worn switch.  
Worn or damaged cords and plugs.  
Any other condition that could ham-  
per the safe operation of this  
machine.  
Plastic parts can easily be cleaned with a  
damp cloth, but never use water to clean  
any electrical parts. Solvents should also  
be avoided on plastic because of the pos-  
sibility of damage.  
Since this tool is encased in a double insu-  
lated plastic cover, leave repair and ser-  
vice issues to a qualified service techni-  
cian. This includes brush replacement,  
lubrication or any other internal operation.  
Be aware of the surrounding conditions.  
Do not use the grinder in the rain, snow or  
near flammable gas and vapors.  
Like all power tools, there is danger  
associated with the Model G9911.  
Accidents are frequently caused by  
lack of familiarity or failure to pay  
attention. Use this tool with respect  
and caution to lessen the possibility of  
operator injury. If normal safety pre-  
cautions are overlooked or ignored,  
serious personal injury may occur.
