damaged, have them repaired by an authorized technician. The handles must be kept clean,  
dry, and free from oil and grease at all times.  
10.  
11.  
Disconnect power. Unplug tool when not in use.  
Remove adjusting keys and wrenches. Check that keys and adjusting wrenches are  
removed from the tool or machine work surface before plugging it in.  
12.  
13.  
Avoid unintentional starting. Be sure the switch is in the Off position when not in use and  
before plugging in. Do not carry any tool with your finger on the switch, whether it is plugged in  
or not.  
The Rotary Hammer must be switched off and unplugged before changing the Knob  
setting. Attempting to change the Knob setting while the motor is engaged will result in abrupt  
bit rotation and can cause serious personal injury and/or property damage.  
14.  
15.  
Stay alert. Watch what you are doing, use common sense. Do not operate any tool when you  
are tired.  
Take caution as some woods contain preservatives such as copper chromium arsenate  
(ccA) which can be toxic. When drilling or chiseling these materials extra care should be  
taken to avoid inhalation and minimize skin contact.  
16.  
check for damaged parts. Before using any tool, any part that appears damaged should be  
carefully checked to determine that it will operate properly and perform its intended function.  
Check for alignment and binding of moving parts; any broken parts or mounting fixtures; and  
any other condition that may affect proper operation. Any part that is damaged should be  
properly repaired or replaced by a qualified technician. Do not use the tool if any switch does  
not turn On and Off properly.  
17.  
18.  
guard against electric shock. Prevent body contact with grounded surfaces such as pipes,  
radiators, ranges, and refrigerator enclosures.  
Replacement parts and accessories. When servicing, use only identical replacement parts.  
Use of any other parts will void the warranty. Only use accessories intended for use with this  
tool. Approved accessories are available from Harbor Freight Tools.  
19.  
20.  
Do not operate tool if under the influence of alcohol or drugs. Read warning labels on  
prescriptions to determine if your judgment or reflexes are impaired while taking drugs. If there  
is any doubt, do not operate the tool.  
use proper size and type extension cord. If an extension cord is required, it must be of the  
proper size and type to supply the correct current to the tool without heating up. Otherwise,  
the extension cord could melt and catch fire, or cause electrical damage to the tool. This tool  
requires use of an extension cord of 0 to 10 amps capability (up to 50 feet), with wire size rated  
at 18 AWg. Longer extension cords require larger size wire. If you are using the tool outdoors,  
use an extension cord rated for outdoor use (signified by “WA” on the jacket).  
21.  
22.  
Maintenance. For your safety, maintenance should be performed regularly by a qualified  
technician.  
WARning: Some dust created by power sanding, sawing, grinding, drilling, and other  
construction activities, contain chemicals known [to the State of California] to cause cancer, birth  
defects or other reproductive harm. Some examples of these chemicals are:  
REV 07c  
SKU 47606  
For technical questions, please call 1-800-444-3353.  
Page 3  
 
- Lead from lead-based paints  
- Crystalline silica from bricks and cement or other masonry products  
- Arsenic and chromium from chemically treated lumber  
Your risk from these exposures varies, depending on how often you do this type of work.  
To reduce your exposure to these chemicals: work in a well ventilated area, and work with  
approved safety equipment, such as those dust masks that are specially designed to filter out  
microscopic particles. (California Health & Safety Code § 25249.5, et seq.)  
23.  
The warnings, cautions, and instructions discussed in this instruction manual cannot cover all  
possible conditions and situations that may occur. It must be understood by the operator that  
common sense and caution are factors which cannot be built into this product, but must be  
supplied by the operator.  
note Performance of this tool (if powered by line voltage) may vary depending on variations in local  
line voltage. Extension cord usage may also affect tool performance.  
unpacking  
When unpacking, check to make sure the parts listed on page 8 are included. If any parts are  
missing or broken, please call Harbor Freight Tools at the number on the cover of this manual as soon  
as possible.  
VibRATiOn HAzARD  
This tool vibrates during use. Repeated or long-term exposure to vibration may cause  
temporary or permanent physical injury, particularly to the hands, arms and shoulders. To  
reduce the risk of vibration-related injury:  
1.  
2.  
Anyone using vibrating tools regularly or for an extended period should first be examined by  
a doctor and then have regular medical check-ups to ensure medical problems are not being  
caused or worsened from use. Pregnant women or people who have impaired blood circulation  
to the hand, past hand injuries, nervous system disorders, diabetes, or Raynaud’s Disease  
should not use this tool. If you feel any medical or physical symptoms related to vibration (such  
as tingling, numbness, and white or blue fingers), seek medical advice as soon as possible.  
Do not smoke during use. Nicotine reduces the blood supply to the hands and fingers,  
increasing the risk of vibration-related injury.  
3.  
4.  
5.  
6.  
Wear suitable gloves to reduce the vibration effects on the user.  
Use tools with the lowest vibration when there is a choice between different processes.  
Include vibration-free periods each day of work.  
To reduce vibration, maintain the tool as explained in this manual. If any abnormal vibration  
occurs, stop use immediately.

Assembly  
Refer to Figure 1.  
1.  
Fit the Handle band (508) over the front of the housing above the Bit Sleeve and screw  
the Handle (506) clockwise to secure. At this point do not fully tighten.  
2.  
Rotate the Handle (506) around the tool until it rests on a flat spot on the housing, on the  
side you prefer.  
note: The Drill Stop (504) is used as a guide when doing repetitive drilling (not chiseling) at  
the same depth.  
3.  
With the Handle (505) still loose, insert the Drill Stop (504) into the hole at the Handle  
base. Fully tighten the Handle (505) clockwise. If you wish to reposition the Handle (505)  
or the Drill Stop (504), loosen the Handle (505) by turning it counterclockwise.

Make sure the Rotary Hammer is not plugged in.  
To insert a bit, pull back and retract the Bit Sleeve (see FIGURE 2) and insert the bit. Slide  
the two notches on the bit into the notched receptacle and then release the Bit Sleeve. Put  
on gloves and then tug on the bit forcefully, making sure it is in the Bit Sleeve firmly.  
3.  
When removing a bit, make sure the bit has had a chance to cool. Wear gloves and grip  
the bit with one hand, and pull back on the Bit Sleeve, retracting it away from the bit. Pull  
out the bit.  
note For safe, optimal performance, keeps bits and chisels properly sharpened. Never use a  
dull, cracked, or chipped bit.  
Bit Sleeve  
note: Break Point (Bull) Bits and cold  
chisels are to be used when the Selector  
Switch is in the hammering position only.  
Using these bits/chisels with the Selector  
Switch in the hammer/drill position will  
result in unexpected tool performance.

Operation  
note: Make sure unit is not plugged in.  
Dust  
Cap  
Fig
note: If you wish, you may attach a Dust cap for overhead  
drilling applications. To do so, after you install a bit,  
before you tighten the Bit Sleeve, slide the Dust cap  
over the bit and adjust the Drill Stop so that the curve on  
the end of the Drill Stop secures the Dust cap. Tighten  
the Handle. See FIGURE 4.  
Curved end  
of Drill Stop  
note: Do not plug in the Rotary Hammer until the bit is loaded, the  
Drill Stop is set, and the Knob selection is complete ( See Below).  
1.  
Following the method on page 4, number 3, under assembly,  
adjust the Drill Stop to the desired length.  
note: The Drill Stop will only work when the Handle is on either side or the top of the Rotary  
Hammer. The body of the Hammer will interfere with the Drill Stop if the Handle is positioned  
on the bottom of the Hammer.  
Warning: When setting the Knob, the Rotary Hammer must be switched off and be  
unplugged. Attempting to change the Knob setting while the motor is engaged will  
result in abrupt bit rotation and can cause serious personal injury and/or property  
damage. See setting the Knob below.  
2.  
Set the Knob to either hammer/drill or hammer. See FIGURE 3 on page 5.  
Hammer Setting: To hammer, turn the Knob so the “T” setting is lined up with the mark  
on the housing.  
Hammer/Drilling: To hammer/drill, set the Knob so the “IT” setting is lined up with the mark  
on the housing.  
note: When setting the Knob make sure it positively clicks into the desired position. if  
Knob does not click into place, it could slip out of position resulting in unexpected  
tool performance.  
3.  
4.  
Install the desired bit or chisel. Only when hammer/drilling use the Drill Stop.  
If hammer/drilling, make sure the Drill Stop and Dust cap, if needed, are installed  
properly.  
5.  
6.  
7.  
The Handle should be rotated to the proper position for the application.  
While keeping you finger off of the Switch, plug in the unit.  
When you are ready to begin, make sure you have a firm grip on both the Main Handle  
and the Handle. Always operate the Rotary Hammer with both hands, holding it securely.  
The Rotary Hammer puts out extreme torque and will kick back and act with great force.  
8.  
Turn on the Switch and allow the Rotary Hammer to run without a load for approximately  
one minute as the unit self-lubricates. Release the Switch, stopping the Hammer. Position  
the chisel or bit on the workpiece and start the Hammer again.  
9.  
After using the Rotary Hammer, release the Switch to turn off the unit.
