OPERATION
WARNING To reduce the risk of in-
jury, keep hands away from all moving parts.
Always wear safety goggles or glasses with
side shields.
WARNING Always remove battery
pack before changing or removing acces-
sories. Only use accessories specifically
recommended for this tool. Others may be
hazardous.
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.
NOTE: 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.
MAINTENANCE
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.
WARNING To reduce the risk of per
sonal injury and damage, never immerse your
tool, battery pack or charger in liquid or allow
a liquid to fl ow inside them.
WARNING To reduce the risk of injury,
always unplug the charger and remove the bat-
tery 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 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.
WARNING To reduce the risk of injury,
keep hands out of the piston area of the tool.
Fingers can be pinched between carriage and
the piston.

RELEASE
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.
