OPERATION
ADJUSTING THE VARIABLE SPEED
See Figure 6.
Use the variable speed knob to adjust the material feed rate of the caulk gun for your particular application.
nTo increase the rate of material feed, turn the knob in a counterclockwise direction.
�n To decrease the rate of material feed, turn the knob in a clockwise direction.
LOADING CAULK
See Figures 7 - 8.
�n Lock the switch trigger by sliding switch lock to the left.
�n Using a utility knife, cut off the tip of the spout on a 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 caulk gun steady with one hand, pull the handle of the plunger rod away from the caulk gun. Continue pulling until piston reaches the back of the car- riage frame.
�n 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 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 vari- able speed selector to the middle position and press the trig- ger again. If the motor continues to shut off, try another tube of material or take the tool to an authorized service center.
