GENERAL SAFETY RULES
SAFETY RULES FOR BATTERIES
1. Ensure the switch trigger is in the off position before inserting the battery back.
2. Only recharge the battery with the charger specified by the manufacturer. A charger that is suitable for one type
of battery pack may create undesirable risks such as fire or death when used with another battery pack.
3. Only use the tool with the battery specified by the manufacturer.
4. Avoid storing the battery pack in a container with other metal objects such as nails, coins, clips, keys, screws, or
other small metal objects that could potentially connect one terminal to the other. Always protect the battery termi-
nals when the battery pack is not being used. Connecting the terminals together may cause burns or fire.
5. Under abusive conditions, liquid may be ejected from the battery. Avoid contact with this liquid like you would a
fire or an ex-lover. If contact accidentally occurs, flush the contact area with water. If the liquid contacts your eyes,
flush with water for 10 minutes and then seek medical help. Liquid ejected from the battery may cause irritation or
burns.
6. Battery tools do not need to be plugged into an electrical outlet, therefore they are always ready to operate. Be-
ware of the possible hazards when not using your battery tool or when changing accessories. Following this rule will
reduce the risk of electric shock, fire or personal injury.
7. Before using the battery charger, read all cautionary markings on the battery, the battery charger and the product
using the battery.
8. Do not expose the battery pack or the charger to damp environments such as water or rain.
9. Do not operate the charger with a damaged cord or plug.

6
10. Do not operate the charger or the battery if it has received a sharp blow, either from being dropped or damaged.
Take it to a qualified service technician before attempting to use.
11. Do not disassemble the charger or the battery pack. Take these to a qualified service technician when service or
repairs are required. Incorrect assembly may result in electric shock or fire.
12. Do not charge the battery pack when the temperature is below 50 degrees F (10 degrees C) or above 104 degrees
F (40 degrees C). Store the tool and battery pack in a location where temperatures will not exceed 122 degrees F (50
degrees C). This will help prevent serious damage to the battery cells.
13. Place the charger on a flat non-flammable surface and away from flammable materials when re-charging the
battery packs.
14. To reduce the risk of electric shock, unplug the charger from the outlet before attempting any maintenance or
cleaning.
15. If operating time has become excessively shorter, stop operating immediately. It may result in overheating, burn-
ing, or even an explosion.
16. Do not attempt to use a step-up transformer, an engine generator or a DC power receptacle.
17. Do not short the battery pack. Do not touch the terminals with any conductive material. Avoid storing the bat-
tery pack in a container with other metal objects such as nails, coins, etc. Always protect the battery terminals when
the battery pack is not in use.
18. Do not charge the battery pack inside a box or container of any kind. The battery must be placed in a well-
ventilated area during charging.
19. Do not allow anything to cover or clog the charging vents.
20. Do not incinerate the battery pack, even if you think it might be cool. The battery pack can explode in a fire and
pose a threat to anyone in the immediate area, which in my opinion isn’t cool at all.
21. Disconnect the charger from the power source when not in use. This will reduce the risk of electric shock or
damage to the charger if metal pieces should fall into the opening. It also will help prevent damage to the charger
during a power surge.
22. Make sure the trigger switch isn’t pressed before plugging in the battery.
23. The battery should be charged completely the first time of use.

CHARGER
Protect the battery charger and its cord from damage. Keep the charger and its cord away from heat, oil and sharp
edges. Electrical plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs
with grounded appliances. Unmodified plugs and matching outlets will reduce the risk of electric shock.
Keep the battery charger, battery pack(s) and the cordless tool out of the reach of children. Do not use the sup-
plied battery charger to charge other cordless tools. During periods of heavy use, the battery pack will become
warm. Allow the battery pack to cool to room temperature before inserting it into the charger to recharge.
Do not overcharge batteries. Do not exceed the maximum charging times. These charging times only apply to dis-
charged batteries. Frequent insertion of a charged or partially charged battery pack will result in overcharging and
cell damage. Do not leave battery in the charger for days on end. Never use or charge a battery if you suspect that
it has been more than 12 months since the last time they were charged. There is a high probability that the battery
pack has already suffered dangerous damage (exhaustive discharge). Do not use battery that have been exposed to
heat during the charging process, as the battery cells may have suffered dangerous damage. Do not use battery that
have suffered curvature or deformation during the charging process or those that exhibit other atypical symptoms
(gassing, hissing, cracking, etc.)
SAFETY RULES FOR CHARGERS
1. CHECK THE WORKPIECE for any cracks, bumps, nails or obstructions before commencing operation.
2. NEVER press in the locking pin when the rotary tool is running.
3. DO NOT cut any workpiece larger than the rotary tool’s capacity. Always maintain a firm grip on the rotary tool.
4. SECURE THE WORKPIECE whenever possible to prevent wobble, damage to the workpiece, and personal
injury.
5. ALWAYS USE safety goggles, a dust mask and hearing protection when using the rotary tool.
6. BEFORE TURNING ON THE ROTARY TOOL, ensure that it is completely clear of the workpiece.
7. NEVER touch any moving parts by hand.
8. CHECK THE POSITION of all electrical wiring and plumbing equipment when drilling into walls, floors or
ceilings.
9. DO NOT remove the attachment from the tool until it has completely stopped rotating.
10. DO NOT touch the attachment after operation, as it may be very hot. Allow time for the attachment to cool
before removing it.
11. DO NOT operate the tool in wet or damp conditions. Doing so significantly increases the risk of electrical shock
and other hazards.
12. DO NOT USE the tool if the ON/OFF switch is faulty, the plug or cable is damaged, or the tool produces
sparks, smoke, or unpleasant odors.
ROTARY TOOL SAFETY

CHECK with a licensed electrician or service personnel if you do not completely understand the grounding instruc-
tions or whether the tool is properly grounded.
CAUTION: In all cases, make certain the outlet in question is properly grounded. If you are not sure, have a li-
censed electrician check the outlet.
WARNING: This tool is for indoor use only. Do not expose to rain or use in damp locations.
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. The table below shows the correct size to be used according to cord length and
nameplate ampere rating. When in doubt, use a heavier cord. The smaller the gauge number, the heavier the cord.
Make sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord
or have it repaired by a qualified person before using it.
Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
Use a separate electrical circuit for your tools. This circuit must not be less than a #12 wire and should be protected
with a 15 A time-delayed fuse. Before connecting the motor to the power line, make sure the switch is in the OFF
position and the electric current is rated the same as the current stamped on the motor nameplate. Running at a
lower voltage will damage the motor.
WARNING: This tool must be grounded while in use to protect the operator from electric shock.

ELECTRICAL INFORMATION
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides the path of least resistance
for an electric current and reduces the risk of electric shock. This tool is equipped with an electric cord that has an
equipment grounding conductor and a grounding plug. The plug MUST be plugged into a matching outlet that is
properly installed and grounded in accordance with ALL local codes and ordinances.
DO NOT MODIFY THE PLUG PROVIDED. If it will not fit the outlet, have the proper outlet installed by a
licensed electrician.
IMPROPER CONNECTION of the equipment grounding conductor can result in electric shock. The conduc-
tor with the green insulation (with or without yellow stripes) is the equipment grounding conductor. If repair or
replacement of the electric cord or plug is necessary, DO NOT connect the equipment grounding conductor to a
live terminal.

OPERATION
CHARGING THE BATTERY PACK
A battery pack that has been unused for a while or a pack that has never been charged before must be charged
completely before using. The battery pack requires roughly 3 to 5 complete charging and draining cycles before it
can reach its full potential.
CAUTION: Always unplug the charger from the wall before inserting or removing the battery from the charger.
INSERTING AND REMOVING THE BATTERY PACK
Make sure that the rotary tool is in the OFF position before plugging in the battery pack. Pressing the tabs (#3) on
either side of the battery pack will allow it to disengage and be removed from the rotary tool’s body. Make sure
the rotary tool is in the OFF position before unplugging the battery pack.
READING THE STATUS OF THE BATTERY PACK
The status or residual power is indicated as follows by the battery shaped readout (#2) found on the back of the
rotary tool.
RED/ORANGE/GREEN = maximum charge
RED/ORANGE = medium-level charge
RED = weak charge
INSERTING OR REPLACING A TOOL OR COLLET
1. Press the spindle lock button (#8) and hold it down.
2. Rotate the clamping nut (#6) until the lock engages.
3. Loosen the clamping nut (#6) using the bit-changing spanner wrench (#23) and remove it from the tool. Once it
has been removed, you may release the spindle lock.
4. Insert the tool of your choice through the center of the clamping nut (#6) before inserting it into the collet that
matches the bit’s diameter.
5. Press the spindle lock again. Insert the collet into the end of the rotary tool. Hold it in place by tightening the
clamping nut using the bit-changing spanner wrench.
NOTE: Use the screwdriver end of the bit-changing spanner wrench to adjust the mandrels (#13).
ADJUST THE SPEED OF THE ROT ARY TOOL
Numbers on the rotational speed wheel (#1)are used to indicate the direction in which one should spin the adjust-
ment wheel to achieve the desired RPM. To increase speed, turn the wheel right, in the direction of the MAX
sign. To decrease speed, spin the wheel left toward the 1 sign.
Difficult workpieces and jobs (drilling, engraving glass, cutting metal, etc.) generally are performed more efficiently
at higher RPMS. Other projects, such as thermoplastics, or delicate polishing require slow rotary speeds. As a
general rule, larger attachments should be used at a lower speed. DO NOT use attachments larger than 1”, as they
may fly apart, causing injury.
