GENERAL SAFETY INSTRUCTIONS
BEFORE USING THIS POWER TOOL
Safety is a combination of common 
sense, staying alert and knowing how 
to use your power tool.
CAUTION
To avoid mistakes that could cause 
serious injury, do not plug the tool in 
until you have read and understood 
the following.
1.   
READ and become familiar with 
the entire Operator’s 
Manual. 
LEARN the tool’s 
application, limitations and 
possible hazards.
2. 
KEEP GUARDS IN PLACE and in 
working order.
3. 
REMOVE ADJUSTING KEYS 
AND WRENCHES. Form the habit 
of checking to see that keys and 
adjusting wrenches are removed 
from the tool before turning ON.
4. 
KEEP WORK AREA CLEAN
Cluttered areas and benches invite 
accidents.
5. 
DO NOT USE IN DANGEROUS 
ENVIRONMENTS. Do not use 
power tools in damp locations, or 
expose them to rain or snow. Keep 
work area well lit.
6. 
KEEP CHILDREN AWAY. All 
visitors and bystanders should be 
kept a safe distance from work 
area.
7. 
MAKE WORKSHOP CHILD 
PROOF with padlocks, master 
switches or by removing starter 
keys.
8. 
DO NOT FORCE THE TOOL. It will 
do the job better and safer at the 
rate for which it was designed.
9. 
USE THE RIGHT TOOL. Do not 
force the tool or an attachment 
to do a job for which it was not 
designed. 
10. 
USE PROPER EXTENSION 
CORDS. Make sure your extension 
cord is in good condition. When 
using an extension cord, be sure 
to use one heavy enough to carry 
the current your product will draw. 
An undersized cord will result in 
a drop in line voltage and in loss 
of power which will cause the tool 
to overheat. The table on page 
10 shows the correct size to use 
depending on cord length and 
nameplate ampere rating. If in 
doubt, use the next heavier gauge. 
The smaller the gauge number, the 
heavier the cord.
11.  
WEAR PROPER APPAREL. Do 
not wear loose clothing, gloves, 
neckties, rings, bracelets or other 
jewelry which may get caught in 
moving parts. Nonslip footwear is 
recommended. Wear protective 
hair covering to contain long hair.
12.             
ALWAYS WEAR EYE 
PROTECTION. Any power 
tool can throw foreign 
objects into the eyes and 
     could cause permanent eye 
damage. 
ALWAYS wear Safety
     Goggles (not glasses) that comply 
with ANSI Safety standard Z87.1. 
Everyday eyeglasses have only 
impact–resistant lenses. They 
ARE NOT safety glasses. Safety 
Goggles are available at sears.
