e. 

Maintain power tools.  Check for 

misalignment or binding of moving 

parts, breakage of parts and any 

other condition that may affect the 

power tool’s operation.  If damaged, 

have the power tool repaired before 

use.  Many accidents are caused 

by poorly maintained power tools.

f. 

Keep cutting tools sharp and clean.  

Properly maintained cutting tools with 

sharp cutting edges are less likely 

to bind and are easier to control.

g. 

Use the power tool, accessories 

and tool bits etc. in accordance 

with these instructions, 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.

5. 

Service

a. 

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.

Breaker Hammer Safety Warnings

1. 

Wear ear protectors. Exposure to 

noise can cause hearing loss.

2. 

Use auxiliary handles supplied 

with the tool. Loss of control 

can cause personal injury.

3. 

Hold power tools 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. 

Keep clear of moving parts.

5. 

Unplug before inspecting, 

removing or installing chisel, 

or performing any service.

6. 

Pull on chisel after installation 

and before use; chisel may move 

but MUST NOT slide out.

7.  Do not operate this tool if you have 

back, neck, or wrist injuries, or other 

conditions that will be aggravated 

by the severe jerking forces that this 

tool exerts upon the operator.

8.  Maintain labels and nameplates 

on the tool.  These carry important 

safety information.  If unreadable 

or missing, contact Harbor Freight 

Tools for a replacement.

9.  Avoid unintentional starting.  Prepare to 

begin work before turning on the tool.

10.  Do not lay the tool down until it has 

come to a complete stop.  Moving 

parts can grab the surface and 

pull the tool out of your control.

11.  When using a handheld power tool, 

maintain a firm grip on the tool with 

both hands 

to resist starting torque.

12.  Do not leave the tool unattended when 

it is plugged into an electrical outlet.

electrical shock.
