the trigger again. If the motor continues to shut off, try
another tube of material or take the tool to an authorized
service center.
WARNING
Battery tools are always in operating condition. Therefore,
switch should always be locked when not in use or carry-
ing at your side.
APPLyING CAULK
See figure 6-8.
■ Prepare the surface to be caulked by removing any
dust, dirt, or remnants of old caulking. Make sure the
area to be caulked is clean and dry.
■ Set the speed of the caulk gun to match your
application needs, using just enough caulk to do the
job. Experiment in an out-of-the-way area to find the
best speed to use to deliver the caulk bead you want.
■ Hold the gun at a slight angle. If filling a crack, insert
the spout into the crack, if possible; otherwise, run the
caulk gun along the surface.
■ Squeeze the trigger on the caulk gun, allowing the
caulk to extrude from the tube tip.
NOTE: If the bead of caulk is too narrow, re-cut the
nozzle to provide a larger opening. However, it is bet-
ter to apply a thin bead of caulk and add a little more
if necessary than to apply too much and attempt to
remove the excess.
■ Carefully move the caulk gun at an even pace along
the gap to be filled as you continue to depress the
switch trigger. Make sure the caulk comes in full
contact with both application surfaces. If necessary,
use your finger to gently press the caulk into a corner
or crack.
NOTE: The best fill is usually achieved by push-
ing the caulk out into the gap in a forward motion.
However, in some cases (particularly where the side
materials are rough or uneven), a pulling motion may
work better as the cartridge will be less likely to get
snagged along the joint.
■ The motor will shut off automatically when a caulk tube
becomes empty. Pull the plunger rod back and replace
the caulk tube as necessary.
■ To end the caulk bead, release the switch trigger.
■ Draw a moistened finger or other "smoothing tool"along
the caulk bead after applying. This will help the caulk
adhere to the application surfaces and will create a
clean, finished appearance.
■ Use a damp towel or rag to clean off any excess caulk.

MAINTENANCE
When servicing, use only original replacement parts. Use
of any other parts may create a hazard or cause product
damage.
Always wear safety goggles or safety glasses with side
shields during power tool operation or when blowing dust.
If operation is dusty, also wear a dust mask.
To avoid serious personal injury, always remove the bat-
tery pack from the tool when cleaning or performing any
maintenance.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, dust, oil, grease, etc.
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal injury.
To work properly, the plunger rod of the tool must remain
clean and free of all caulk and adhesive material. If
material does get on the plunger rod mechanism, clean
the material off according to the directions of the caulk or
adhesive manufacturer.
When the tool is shut off by the electronic overload
protection system, always wait for 3 to 5 seconds before
depressing the trigger for restart. Frequently depressing
and releasing the trigger under these circumstances may
cause interior damage to the caulk gun.
Only the parts shown on the parts list are intended to
be repaired or replaced by the customer. All other parts
should be replaced at an Authorized Service Center.
