Troubleshooting; Maintenance - Milwaukee M12 GG User Manual

Temperatures in excess of 50°C (122°F) reduce the
performance of the battery pack. Avoid extended exposure to
heat or sunshine (risk of overheating).
The contacts of chargers and battery packs must be kept clean.
For an optimum lifetime, the battery packs have to be fully
charged after use.
To obtain the longest possible battery life, remove the battery
pack from the charger once it is fully charged.
For battery pack storage longer than 30 days:
● Store the battery pack where the temperature is below
27°C and away from moisture.
● Store the battery packs in a 30% – 50% charged condition.
● Every six months of storage, charge the pack as normal.

The battery pack has overload protection that protects it from

Under extreme stress, the battery electronics turn off the
product automatically. To restart, turn the product off and then
on again. If the product does not start up again, the battery

away from the body.
Pull the trigger for 3 seconds, release, and repeat until grease
begins to fl ow from the fi tting.
If after several attempts grease does not appear, manually
prime the grease gun:
1. Pull back the rod, and turn the rod handle to lock into the
plunger.
2. Press in the bleed valve while manually pressing in the rod.
Once grease begins to flow from the fitting, rotate the rod
handle to release the plunger. Press the rod completely into
the cylinder.
NOTE: The product has been tested to factory standards,
which results in a small amount of grease being left in the
pump body, hose, and coupler assembly. Purge the product
with the brand of grease you will be using before actual use.
