power supply. See Figure 1.
To charge battery module:
1. 

Lift charge port cover.

2. 

Insert charging cord into charging port.

Charging Error

*Charger will automatically shut down when these indicators are displayed. Unplug machine to reset 
battery. Plug machine back in to resume charging.

The compatible charger(s) will not charge a faulty battery pack. The charger will indicate faulty battery 
pack by refusing to light.

NOTE: 

This could also mean a problem with the charger. If the charger indicates a problem, take the charger 

and machine to be tested at an authorized service center.

Hot/Cold Pack

When the charger detects a battery pack that is too hot or too cold to charge, it will display one of the 
Hot/Cold Pack indicators and shut down. To resume charging, unplug the machine, allow the charger to 
reset, then plug the machine back in following the instructions provided earlier in this manual.

Important Charging Notes

1. 

Longest life and best performance can be obtained if the machine is charged when the air 
temperature is between (65° F - 75° F (18° C - 24° C). Charger will only charge when battery 
pack temperature is b40° F (+4.5° C) and +104° F (+40° C).

NOTE: 

Charger will not allow charging when battery pack temperature is below +40° F (+4.5° C), or above 

+104° F (+40° C). 

2. 

The charger and machine may become warm to the touch while charging. This is a normal 
condition, and does not indicate a problem. To facilitate the cooling of the machine after use, 
avoid placing the charger or machine in a warm environment such as in a metal shed or an 
uninsulated trailer.

3. 

If the machine does not charge properly:
a. 

Check operation of receptacle by plugging in a lamp or other appliance;

b. 

Check to see if receptacle is connected to a light switch which turns power off when 
you turn out the lights;

c. 

Move the charger and machine to a location where the surrounding air temperature is 
approximately 65° F - 75° F (18° C - 24° C);

d. 

If charging problems persist, take the charger and machine to your local service center.

4. 

The machine should be recharged when it fails to produce sufficient power on jobs which were 
easily done previously. DO NOT CONTINUE to use under these conditions. Follow the charging 
procedure. You may also charge a partially used machine whenever you desire with no adverse 
effect on the battery pack.

5. 

Foreign materials of a conductive nature such as, but not limited to, grinding dust, metal 
chips, steel wool, aluminum foil or any buildup of metallic particles should be kept away from 
charger cavities. Always unplug the charger from the power supply when not charging the 
machine. Unplug the charger before attempting to clean.

6. 

DO NOT freeze or immerse the charger in water or any other liquid.

Charger Cleaning Instructions

 WARNING

Shock hazard. Disconnect the charger from the AC outlet before cleaning. Dirt and grease may be 

removed from the exterior of the charger using a cloth or soft non-metallic brush. DO NOT use water or 

any cleaning solutions.

Storage Recommendations

1. 

The best storage place is one that is cool and dry, away from direct sunlight and excess heat 
or cold.

2. 

For long storage, it is recommended to store a fully charged machine in a cool dry place with 
the charger disconnected for optimal results.

NOTE: 

Machine should not be stored completely depleted of charge. The machine will need to be 

recharged before use.

Maintenance

Repairs

The charger and battery pack are not serviceable. There are no serviceable parts inside the charger or 
battery pack.

 WARNING

To assure product SAFETY and RELIABILITY, repairs, maintenance and adjustment (including motor brush 

inspection and replacement, when applicable) should be performed by a factory authorized service 

center. Always use Original Equipment Manufacturer (OEM) replacement parts.
