OPERATION
STARTING/STOPPING THE CAULK GUN
See Figure 5.
Before attempting to start the caulk gun, be sure the switch lock is in the unlocked position.
nTo turn the caulk gun ON, depress the switch trigger. �n To turn the caulk gun OFF, release the switch trigger.
LOCKING THE SWITCH TRIGGER
See Figure 5.
The switch trigger of the caulk gun can be locked off using the slide switch located below the switch trigger.
nTo lock the switch trigger, slide the switch lock up. This will prevent the caulk gun switch trigger from being de- pressed.
nTo unlock the switch trigger, slide the switch down. This will allow the caulk gun switch trigger to be depressed.
LOADING CAULK
See Figures 6 - 7.
nLock the switch trigger by sliding the switch lock up.
nUsing 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.
nCheck 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.
nWhile 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.
nLoad 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 protec- tion 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
