Power tool use and care 
16.  Do not force the power tool. Use the correct 
power tool for your application. The correct 
power tool will do the job better and safer at the 
rate for which it was designed. 
17.  Do not use the power tool if the switch does 
not turn it on and off. Any power tool that cannot 
be controlled with the switch is dangerous and 
must be repaired. 
18.  Disconnect the plug from the power source 
and/or the battery pack from the power tool 
before making any adjustments, changing 
accessories, or storing power tools.
 Such 
preventive safety measures reduce the risk of 
starting the power tool accidentally. 
19.  Store idle power tools out of the reach of 
children and do not allow persons unfamiliar 
with the power tool or these instructions to 
operate the power tool.
 Power tools are 
dangerous in the hands of untrained users. 
20.  Maintain power tools. Check for misalignment 
or binding of moving parts, breakage of parts 
and any other condition that may affect the 
power tools operation. If damaged, have the 
power tool repaired before use.
 Many accidents 
are caused by poorly maintained power tools. 
21.  Keep cutting tools sharp and clean. Properly 
maintained cutting tools with sharp cutting edges 
are less likely to bind and are easier to control. 
22.  Use the power tool, accessories and tool bits 
etc. in accordance with these instructions and 
in the manner intended for the particular type 
of power tool, taking into account the working 
conditions and the work to be performed.
 Use 
of the power tool for operations different from 
those intended could result in a hazardous 
situation. 
Service 
23.  Have your power tool serviced by a qualified 
repair person using only identical replacement 
parts.
 This will ensure that the safety of the power 
tool is maintained. 
24.  Follow instruction for lubricating and 
changing accessories. 
25.  Keep handles dry, clean and free from oil and 
grease. 
USE PROPER EXTENSION CORD. 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 cause a drop in line voltage resulting in loss of 
power and overheating. Table 1 shows the correct size to 
use depending on cord length and nameplate ampere 
rating. If in doubt, use the next heavier gage. The smaller 
the gage number, the heavier the cord.

SPECIFIC SAFETY RULES 
DO NOT let comfort or familiarity with product 
(gained from repeated use) replace strict adherence 
to grinder safety rules. If you use this tool unsafely 
or incorrectly, you can suffer serious personal 
injury. 
1. 
Always use proper guard with grinding wheel. 
A guard protects operator from broken wheel 
fragments. 
2. 
Accessories must be rated for at least the 
speed recommended on the tool warning label.
 
Wheels and other accessories running over rated 
speed can fly apart and cause injury. 
3. 
Hold tool by insulated gripping surfaces when 
performing an operation where the cutting tool 
may contact hidden wiring or its own cord.
 
Contact with a "live" wire will make exposed metal 
parts of the tool "live" and shock the operator. 
4.  When using depressed center grinding wheels, 
be sure to use only fiberglass-reinforced 
wheels. 
5. 
Always use safety glasses or goggles. 
Ordinary eye or sun glasses are NOT safety 
glasses. 
6. 
Check the wheel carefully for cracks or 
damage before operation. Replace cracked or 
damaged wheel immediately. Run the tool 
(with guard) at no load for about a minute,
