Milwaukee 2441-20 n User Manual

5. Insert tube into the carriage.
6. Push the rod handle forward until the piston is 

against the tube.

7. Push the control switch to the Forward position. 
8. To remove the tube, push the control switch to the 

Rack Release position and pull the rod handle 
back. Lift the tube out of the carriage.

Installing Sausage Type Pack
Always check sausage packs for punctures or 
damage before installing. Do not use a damaged 
or frozen pack.
1. Push the control switch to the Rack Release 

position. Remove the battery pack.

2. Pull the rod handle back to allow the pack to fi t 

inside the barrel

3. Insert pack into barrel.
4. Cut off end of sausage pack per manufacturer's 

recommendation.

Before using a partially fi lled pack, re-

move any hardened material.

5. Insert nozzle supplied with the sausage pack 

into the nozzle cap and screw onto the barrel

6. Cut nozzle at an angle and size per manufac-

turer's recommendation to suit the job (unless 
the nozzle is pre-cut). A smaller nozzle diameter 
requires more force to push the caulk and re-
duces battery life.

7. Push the rod handle forward until the piston is 

against the pack.

8. Push the control switch to the Forward position. 

Using the Control Switch
The control switch may be set to two positions: 
forward and rack release.
For 

forward, push in the control 

switch from the right side of the tool. 
The tool will run normally.
To 

lock the trigger and release the 

rack, push in the control switch from 
the left side of the tool. The rack 
can be moved to the desired posi-
tion. The trigger will not work while 
the control switch is in the locked 
position. Always lock the trigger 
or remove the battery pack before 
performing maintenance, changing 
accessories, storing the tool and 
any time the tool is not in use.

Fuel Gauge
To determine the amount of charge left in the bat-
tery, pull the trigger. The Fuel Gauge will light up 
for 2-3 seconds. 
To signal the end of charge, 1 light on the fuel 
gauge will fl ash for 2-3 seconds. 
Anti-Drip and Rod Release
The caulk gun features an automatic anti-drip to 
prevent drips after the trigger is released.    
End of travel
When a tube is emptied, the motor will automatically 
reverse to release pressure, then shut off. Release 
the trigger and change the tube.  
Overload
When an overload occurs, the tool will reach the 
maximum drive force and continue to hold this 
maximum force until the user releases the trigger. 
If material is not dispensing, 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
• Rod is free of caulk/adhesive materials
Starting and Stopping and Controlling Speed
1. Pull trigger to dispense material.
2. Increase or decrease pressure on the trigger to 

dispense the material. Adjust the speed dial to 
select the maximum speed for proper bead width 
and material fl ow rate ("1" for slowest, "6" for 
fastest).  The trigger pressure, selected speed, 
material type, temperature and nozzle diameter 
will all affect the fl ow rate. When using a tube or 
pack with a smaller nozzle diameter use a slower 
speed or the material may be forced around the 
rear tube seat.

  NOTE: Operating the gun at high speeds may 

damage the dispensing tube or pack for some 
materials. For best results, gradually increase 
speed settings.

3. Release trigger to stop dispensing material. 

NOTE: The piston will stop automatically when it 
has reached the end of the tube.

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 
include gasoline, turpentine, lacquer thinner, paint 
thinner, chlorinated cleaning solvents, ammonia 
and household detergents containing ammonia. 
Never use flammable or combustible solvents 
around tools.
Repairs
For repairs, return the tool, battery pack and char-
ger to the nearest service center.

Maintaining Tool 
Keep your tool, battery pack and charger in good 
repair by adopting a regular maintenance program. 
After six months to one year, depending on use, 
return the tool, battery pack and charger to A 
MILWAUKEE service facility for:
• Lubrication
• 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.

Installing Caulk or Adhesive Tube
Always check tubes for punctures or damage 
before installing. Do not use a damaged or frozen 
tube.
1. Push the control switch to the Rack Release 

position. Remove the battery pack.

2. Cut nozzle of tube at an angle and size per 

manufacturer's recommendation to suit the job 
(unless the nozzle is pre-cut). A smaller nozzle 
diameter requires more force to push the caulk 
and reduces battery life.

3. Break the inner seal of the tube. If the inner seal 

is not broken, the caulk material may be forced 
out the rear end of the tube and damage the 
tool.

 NOTE: Before using a partially fi lled tube, re-

move any hardened material with a long nail or 
piece of wire.

4. Pull the rod handle back to allow the tube to fi t 

inside the carriage.
