This will allow the caulk gun switch trigger to be
depressed.
LOADING CAULK (NOT INCLUDED)
See figure 4-5.
Lock the switch trigger by sliding the switch lock up.
Using a utility knife, cut off the tip of the spout on a
standard 10 oz. tube of caulk. Cut the tip at a 45°
angle.
Remove as little as possible, taking into consideration
the size of the "bead" of caulk you need.
Check for a second inner seal at the base of the spout.
If found, insert the puncture tool inside the spout to
break the seal before using. If using a partially filled
tube, use the puncture tool to remove any hardened
material from the tip.
NOTE: An inner seal is usually found only in card-
board caulk tubes.
While holding the caulk gun steady with one hand, pull
the handle of the plunger rod away from the caulk gun.
Continue pulling until plunger base reaches the back
of the carriage frame.
Load the caulk tube into the carriage frame, making
sure it is well seated at both ends.
ELECTRONIC OVERLOAD PROTECTION
The caulk gun is protected by an electronic overload
protection feature. If too much pressure is exerted on
the tube, the motor will shut down. This helps to prevent
damage to the tool and the caulk tube. 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
Release the trigger and wait for 3 to 5 seconds to allow the
electronics to reset. If the motor again shuts off, move the
variable speed selector to the middle position and press
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
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
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.
