Milwaukee 6560 Series manual Maintenance

Electronic Overload Protection

The gun is protected by an electronic over- load protection feature. If too much pres- sure is exerted on the tube, the motor will automatically reverse for one second, and then shut down. This helps to prevent dam- age to the tool and the caulk tube or pack.

If the motor shuts off, make sure that:

•Nozzle tip is cut

•Inner seal in the caulk tube is broken

•Hardened material is removed from the nozzle

•Caulk tube is not damaged or frozen

•Plunger rod is free of caulk/adhesive materials

Release trigger to allow the electronics to reset. If the motor continues to shut off, try another tube of material or take the tool to a MILWAUKEE Service Center.

Auto-Reverse Mechanism

This tool has an auto-reverse feature that reverses the plunger when the trigger is pressed for more than 2 seconds and released. This feature helps stop excess material from continuing to flow.

Pulsing the trigger will deactivate the auto- reverse mechanism and allow for contin- ued pressure on the tube. This helps main- tain a slower material feed rate.

Auto-Shut Off

When a caulk tube is empty, the auto-shut off feature will turn the motor off. Pull the plunger back and replace the tube.

Caution: Unexplained tool shut-off or auto-reverse may be due to caulk or adhe- sive material on the plunger rod. Plunger rod must remain clean and free of all caulk and adhesive material. If material does get on plunger rod mechanism, remove the plunger rod and clean the material off of the rod and tool with a brush and solvent according to the caulk or adhesive material's manufacturer.

MAINTENANCE

WARNING!

To reduce the risk of personal injury, always unplug the charger and remove the battery pack from the charger or tool before per- forming any maintenance. Never disassemble the tool, battery pack or charger. Contact a

MILWAUKEE service facility for ALL repairs.

Maintaining Tool

Keep your tool, battery pack and charger in good repair by adopting a regular main- tenance program. After six months to one year, depending on use, return the tool, battery pack and charger to a MILWAUKEE service facility for:

•Lubrication

•Brush inspection and replacement

•Mechanical inspection and cleaning (gears, spindles, bearings, housing, etc.)

•Electrical inspection (battery pack, charger, motor)

•Testing to assure proper mechanical and electrical operation

If the tool does not start or operate at full power with a fully charged battery pack, clean the contacts on the battery pack. If the tool still does not work properly, return the tool, charger and battery pack to a MILWAUKEE service facility for repairs.

Maintaining Battery Pack

MILWAUKEE battery packs will operate for many years and/or hundreds of cycles when they are maintained and used ac- cording to these instructions.

A battery pack that is stored for six months without being used will discharge itself. Batteries discharge at a rate of about 1% per day. Charge the battery every six months even if it is unused to maximize battery life. Do not tape the trigger in the “ON” position and leave the tool unattended as this may discharge the battery to a point where it will no longer be able to recharge. Use a MILWAUKEE battery pack only until it no longer performs with the power and torque needed for your application.

Store your battery pack in a cool, dry place. Do not store it where the temperature may exceed 120°F (50°C) such as in a vehicle or metal building during the summer. High temperatures will overheat the battery pack, reducing battery life. If it is stored for sev- eral months, the battery pack will gradu- ally lose its charge. One to three cycles of charging and discharging through normal use will restore the capacity of the battery pack. During the life of the battery pack, the operating time between charges be- comes shorter. If the operating time be- comes extremely short after a proper charge, the usable life of the battery pack has been reached and it should be replaced.

WARNING!

To reduce the risk of personal injury and damage, never immerse your tool, battery pack or charger in liquid or allow a liquid to flow inside them.

Cleaning

Clean dust and debris from charger and tool vents. Keep tool handles clean, dry and free of oil or grease. Use only mild soap and a damp cloth to clean the tool, battery pack and charger since certain cleaning agents and solvents are harmful to plastics and other insulated parts. Some of these in- clude gasoline, turpentine, lacquer thinner, paint thinner, chlorinated cleaning solvents, ammonia and household detergents con- taining ammonia. Never use flammable or combustible solvents around tools.

WARNING!

To reduce the risk of explosion, never burn a battery pack even if it is damaged, dead or completely discharged.
