OPERATION
If releasing the trigger does not reset the battery and
tool, the battery pack is depleted. If depleted, the battery
pack will begin charging when placed on the lithium-ion
charger.
STARTING/STOPPING THE CAULK GUN
(Fig. 3)
Before attempting to start the caulk gun, be sure the
switch lock is in the unlocked position.
■
To turn the caulk gun ON, depress the switch trigger.
■
To turn the caulk gun OFF, release the switch trigger.
LOCKING THE SWITCH TRIGGER (Fig. 3.)
The switch trigger of the caulk gun can be locked off
using the slide switch located below the switch trigger.
■
To lock the switch trigger, slide the switch lock up.
This will prevent the caulk gun switch trigger from
being depressed.
■
To unlock the switch trigger, slide the switch down.
This will allow the caulk gun switch trigger to be
depressed.
LOADING CAULK (NOT INCLUDED) (Fig. 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 cardboard
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
■
Plunger rod is free of caulk/adhesive materials
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 carrying at your side.
APPLYING CAULK (Fig. 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
better 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 pushing
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.
