12.    The battery Charger gets hot during 
  use. The Charger’s heat can build 
  up to unsafe levels and create a fire 
  hazard if it does not receive adequate 
ventilation, due to an electrical fault, or if it is used 
in a hot environment. Do not place the Charger 
on a flammable surface. Do not obstruct any 
vents on the Charger. Especially avoid placing 
the Charger on carpets and rugs; they are not 
only flammable, but they also obstruct vents 
under the Charger. Place the Charger on a 
stable, solid, nonflammable surface (such as a 
stable metal workbench or concrete floor) at least 
1 foot away from all flammable objects, such as 
drapes or walls. Keep a fire extinguisher and a 
smoke detector in the area. Frequently monitor 
the Charger and Battery Pack while charging.

Vibration Safety
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.  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.
2.  Do not smoke during use. Nicotine reduces 
the blood supply to the hands and fingers, 
increasing the risk of vibration-related injury.
3.  Wear suitable gloves to reduce the 
vibration effects on the user.
4.  Use tools with the lowest vibration when there 
is a choice between different processes.
5.  Include vibration-free periods each day of work.
6.  Grip tool as lightly as possible (while still keeping 
safe control of it). Let the tool do the work.
7.  To reduce vibration, maintain the tool as 
explained in this manual. If any abnormal 
vibration occurs, stop use immediately.
 SAVE THESE 
INSTRUCTIONS.
GROUNDING
TO PREVENT ELECTRIC SHOCK AND 
DEATH FROM INCORRECT GROUNDING: 
Check with a qualified electrician if you 
are in doubt as to whether the outlet is 
properly grounded. Do not modify the power cord 
plug provided with the charger. Never remove the 
grounding prong from the plug. Do not use the tool 
if the power cord or plug is damaged. If damaged, 
have it repaired by a service facility before use. If 
the plug will not fit the outlet, have a proper outlet 
installed by a qualified electrician.
