tion  
eliminates the need for the three wire  
grounded power cord and grounded power  
supply system.  
14. Use safety equipment. Always wear eye  
protection. Dust mask, non-skid safety  
shoes, hard hat, or hearing protection must  
be used for appropriate conditions. Ordinary  
eye or sun glasses are NOT eye protection.  
5. Avoid body contact with grounded sur-  
faces such as pipes, radiators, ranges and  
refrigerators. There is an increased risk of  
electric shock if your body is grounded.  
Tool Use and Care  
6. Do not expose power tools to rain or wet  
conditions. Water entering a power tool will  
increase the risk of electric shock.  
15. Use clamps or other practical way to  
secure and support the workpiece to a  
stable platform. Holding the work by hand or  
against your body is unstable and may lead  
to loss of control.  
7. Do not abuse the cord. Never use the cord  
to carry the tools or pull the plug from an  
outlet. Keep cord away from heat, oil,  
sharp edges or moving parts. Replace  
damaged cords immediately. Damaged  
cords increase the risk of electric shock.  
16. Do not force tool. Use the correct tool for  
your application. The correct tool will do the  
job better and safer at the rate for which it is  
designed.  
8. When operating a power tool outside, use  
an outdoor extension cord marked “W-A”  
or “W”. These cords are rated for outdoor  
use and reduce the risk of electric shock.  
17. Do not use tool if switch does not turn it  
on or off. Any tool that cannot be controlled  
with the switch is dangerous and must be  
repaired.  
Personal Safety  
18. Disconnect the plug from the power  
source before making any adjustments,  
changing accessories, or storing the tool.  
Such preventive safety measures reduce the  
risk of starting the tool accidentally.  
9. Stay alert, watch what you are doing and  
use common sense when operating a  
power tool. Do not use tool while tired or  
under the influence of drugs, alcohol, or  
medication. A moment of inattention while  
operating power tools may result in serious  
personal injury.  
19. Store idle tools out of reach of children  
and other untrained persons. Tools are  
dangerous in the hands of untrained users.  
10. Dress properly. Do not wear loose cloth-  
ing or jewelry. Contain long hair. Keep  
your hair, clothing, and gloves away from  
moving parts. Loose clothes, jewelry, or  
long hair can be caught in moving parts.  
20. Maintain tools with care. Keep cutting  
tools sharp and clean. Properly maintained  
tools with sharp cutting edges are less likely  
to bind and are easier to control.  
21. Check for misalignment or binding of  
moving parts, breakage of parts, and any  
other condition that may affect the tools  
operation. If damaged, have the tool ser-  
viced before using. Many accidents are  
caused by poorly maintained tools.  
11. Avoid accidental starting. Be sure switch  
is off before plugging in. Carrying tools with  
your finger on the switch or plugging in tools  
that have the switch on invites accidents.  
12. Remove adjusting keys or wrenches  
before turning the tool on. A wrench or a  
key that is left attached to a rotating part of  
the tool may result in personal injury.

22. Use only accessories that are recom-  
mended by the manufacturer for your  
model. Accessories that may be suitable for  
one tool, may become hazardous when used  
on another tool.  
tenance performed by unqualified personnel  
could result in a risk of injury.  
24. When servicing a tool, use only identical  
replacement parts. Follow instructions in  
the Maintenance section of this manual.  
Use of unauthorized parts or failure to follow  
Maintenance instructions may create a risk of  
electric shock or injury.  
SERVICE  
23. Tool service must be performed only by  
qualified repair personnel. Service or main-  
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 num-  
ber, the heavier the cord.

Hammer drilling operation  
CAUTION:  
OPERATION  
There is a tremendous and sudden twisting force  
exerted on the tool/bit at the time of hole break-through,  
when the hole becomes clogged with chips and  
particles, or when striking reinforcing rods embedded in  
the concrete. Always use the side grip (auxiliary handle)  
and firmly hold the tool by both side grip and switch  
handle during operations. Failure to do so may result in  
the loss of control of the tool and potentially severe  
injury.  
When drilling in concrete, granite, tile, etc., move the action  
mode changing lever to the position of  
symbol to use  
rotation with hammeringaction.  
Be sure to use a tungsten-carbide tipped bit.  
Position the bit at the desired location for the hole, then pull  
the switch trigger. Do not force the tool. Light pressure gives  
best results. Keep the tool in position and prevent it from slip-  
ping away from the hole.  
Do not apply more pressure when the hole becomes clogged  
with chips or particles. Instead, run the tool at an idle, then  
remove the bit partially from the hole. By repeating this sev-  
eral times, the hole will be cleaned out and normal drilling  
may be resumed.  
001302  
Blow-out bulb (optional accessory)  
After drilling the hole, use the blow-out bulb to clean the dust  
out of the hole.

Drilling operation  
When drilling in wood, metal or plastic materials, move the  
action mode changing lever to the position of  
symbol to  
use rotation onlyaction.  
Drilling in wood  
When drilling in wood, the best results are obtained with  
wood drills equipped with a guide screw. The guide screw  
makes drilling easier by pulling the bit into the workpiece.  
10  
Drilling in metal  
To prevent the bit from slipping when starting a hole, make  
an indentation with a center-punch and hammer at the point  
to be drilled. Place the point of the bit in the indentation and  
start drilling.  
Use a cutting lubricant when drilling metals. The exceptions  
are iron and brass which should be drilled dry.  
CAUTION:  
Pressing excessively on the tool will not speed up the  
drilling. In fact, this excessive pressure will only serve to  
damage the tip of your bit, decrease the tool  
performance and shorten the service life of the tool.  
There is a tremendous force exerted on the tool/bit at the  
time of hole break through. Hold the tool firmly and exert  
care when the bit begins to break through the workpiece.  
A stuck bit can be removed simply by setting the  
reversing switch to reverse rotation in order to back out.  
However, the tool may back out abruptly if you do not  
hold it firmly.  
Always secure small workpieces in a vise or similar hold-  
down device.  
MAINTENANCE  
CAUTION:  
Always be sure that the tool is switched off and  
unplugged before attempting to perform inspection or  
maintenance.  
004290  
Indicator lamp  
The green power-ON indicator lamp lights up when the tool is  
switched ON. If the indicator lamp is lit but the tool does not  
start, the carbon brushes may be worn out, or the electric cir-  
cuit or the motor may be defective. If the indicator lamp does  
not light up and the tool does not start, the ON/OFF switch or  
the mains cord may be defective.
