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 cauIWadhesive 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.
APPLY(NG CAULK
See Figures 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.
