Preparation of the safe:
The holes necessary to mount the lock and entry device correspond with the standard dimensions for mechanical locks. The spindle
hole must be deburred with no sharp edges.
1). Drill mounting holes for US 8-32 or M4 screws and a cable hole, see Figure 1.
Using the two (2) 8-32 mounting screws mount the dial plate (P/N 3752) onto the tapped holes on the door.
2). The dial plate must be centered over the spindle hole. The dial plate should be mounted with the arrows in the up position.
• Tapped holes on the door should be at 12:00 and 6:00 locations, see Figure 3.
3). Install the cable protector on the entry over the cable and install over the large and small pins on the housing.
• It is important to make surethe cable will not rub on the dial plate after assembly,see Figure 4.
Mounting
Screws (2)
The 3750-K comes with two pin and spring assemblies in the hardware pak. Both should be used to ensure proper
installation of the keypad.
4). Place the spring over the small end of the pin and put one assembly in each of the holes in the back of the keypad housing,
near the battery opening, see Figure 5.
5). Feed the cable through the hole on the door.
6). Place the shoulder bushing (Figure 4)in the holes of the dial plate (Figure 6)and rotate the keypad so that the keypad is
aligned correctly.
•Aclick will be heardwhen the pin and springs snap into place in the two holes located on the dial plate, see Figure 6.
7). Keypad should be locked into place and should not move in either direction.

14). Using the three (3) mounting screws provided by the factory, screw down the lock to the mounting plate or door.
• Make sure you do not pinch the wires, see Figure 9.
15). Secure entry cable with a wire tie, making sure that any extra cable is in a safe position and cannot be damaged by any moving
parts or sharp edges, see Figure 10.
LA GARD recommends the torque setting of 30 inch/pounds (3.4 newton/meters) when installing the Swingbolt™ lock.
8). Install the cable clamp over the cable on the inside of the door with the flat side facing the door.
9). Slide down to the hole to protect the cable from rubbing on the edge of the hole.
10). Gently pull on the cable to assure that there is no excess cable in the hole that would rub on the metal door.
11). Route the cable on the notch of the cable clamp as shown, see Figure 7.
12). Press the snap connector toward the bottom of the lock.
13). Carefully insert the entry cable plug into the lock at the “ENT” position, see Figure 8.
CHANGING YOUR BATTERY
1). Remove black plastic battery compartment cover (located at the bottom of the keypad)
by gently pulling downwardon its handle.
2). Allow the battery and its attached leads to drop down and out of the battery
compartment. If it does not drop, gently pull on the battery until it drops out.
3). The connector is easily removed by unsnapping it from the two terminals on the top of
the battery.
Never Pull on the Battery Leads
4). Connect a new 9-Volt Alkaline battery to the battery clip.
5). Gently push the battery and the leads completely up into the battery compartment.
6). Install the battery cover by placing one side of the cover in position first and then gently
pressing the other side into place.
