STARTING/STOPPING THE CAULKING GUN
See Figure 5.
Before attempting to start the caulking gun, be sure the
switch lock is in the unlocked position.
n
To turn the caulking gun ON, depress the switch trigger.
n
To turn the caulking gun OFF, release the switch trigger.
LOCKING THE SWITCH TRIGGER
See Figure 5.
The switch trigger of the caulking gun can be locked off
using the slide switch located below the switch trigger.
n
To lock the switch trigger, slide the switch lock up. This
will prevent the caulking gun switch trigger from being
depressed.
n
To unlock the switch trigger, slide the switch down. This will
allow the caulking gun switch trigger to be depressed.
LOADING CAULK
See Figures 6 - 7.
n
Lock the switch trigger by sliding the switch lock up.
n
Using a utility knife, cut off the tip of the spout on a
standard 300 g 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.
n
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.
n
While holding the caulking gun steady with one hand,
pull the handle of the plunger rod away from the caulking
gun. Continue pulling until plunger base reaches the
back of the carriage frame.
n
Load the caulk tube into the carriage frame, making sure
it is well seated at both ends.
ELECTRONIC OVERLOAD PROTECTION
The caulking 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:
n
Nozzle tip is cut
n
Inner seal in the caulk tube is broken
n
Hardened material is removed from the nozzle
n
Caulk tube is not damaged or frozen
n
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
