LUBRICATING THE CORES
Do not lubricate cores with oil. Doing so will only attract dirt.
Caution

For powdered graphite lubrication:
1. Dip a key in graphite. Insert the key into the keyhole and remove it;
repeat several times. OR
Spray graphite into the keyhole. Insert the key into the keyhole and
remove it; repeat several times.
2. Allow the graphite to sift into the pin segment holes.

For silicone type lubrication:
1. Clean all existing lubricant out of the core.
Do not mix graphite with a silicone-type lubricant.
Caution

2. With the core inverted, spray the lubricant into the key opening
allowing the spray to penetrate the pin segment holes.
Note: When cores are installed and exposed to harsh weather

conditions, silicone-type lubricants can help displace moisture as
well as spread into pin segment holes and other surfaces.

ALIGNING THE CHASSIS AND TRIM
Establish a schedule to inspect locks, doors, and door hardware for
proper alignment and operation. Occasionally a lock chassis and/or rose
trim may become lose and require tightening.

To retighten a loose or misaligned chassis or rose trim:
1. Remove the inside trim. See page 3–4 for instructions.
2. Align the chassis with the latch. Make sure that the latch tabs engage
the chassis frame and the latch tailpiece engages the retractor, as
shown in Figure 3.32.

Before you install the core and throw member, you can see that the
inside locking cam is not positioned as shown in Figure 3.33.
Perform the following steps to reposition the inside locking cam.

To reposition the locking cam:

Vibration during the shipment of the G and IN function locks may cause
the inside locking cam to rotate out of position. You might notice this
problem in one of the following ways.
■ With the levers in the locked position, both the inside and outside
keys do not rotate one full turn in both directions. Remove both
cores and throw members, and perform the following steps to
reposition the locking cam.
■ Before you install the core and throw member, you can see that the
locking cam is not positioned as shown in Figure 3.34. Perform the
following steps to reposition the locking cam.

To reposition the locking cam:
1. Looking through the figure-8 core hole in either lever, turn the

1 In alignment with the center of the latchbolt, mortise the door jamb
to fit the strike box and strike plate.
Caution: The deadlocking plunger of the latchbolt must not
enter the strike plate opening. The plunger deadlocks the
latchbolt and prevents forcing the latch when the door is
closed. A gap of more than 1/8” may reduce security and/or
cause improper operation of the latchbolt.

6-pin cores — over the 7-pin throw member (see Figure 8, top right).
Note: If you have ordered 6-pin cores, you will get one spacer per core
with your order. Spacers are not supplied with locks.
1 Insert the throw member (or throw member and spacer) into the
back of the core (see Figure 8, top).
2 Put the control key into the core and turn the key 15 degrees clockwise.
3 Put the core and throw member into the lever with the control key

Total footage of two conductor cable for lock circuit (in feet)
Figure 2—Minimum gauge wire chart for lock circuits
To find the correct gauge wire

Installation hints

1 Determine the maximum lock current and find that value on the left
side of the chart.
2 Determine the total footage of cable to be used in the lock circuit
and find that value at the bottom of the chart.
3 Locate the intersection of current and footage. The line above or to
the right of the intersection shows what minimum gauge wire you
need.

1 Wire gauge (or size) determines how efficiently the lock will operate.
Consider wire gauge before installation. To find the recommended
minimum wire gauge for all wire runs, see Figure 2.
2 Use wire of 20 AWG (gauge) or larger. We do not recommend using a
smaller wire gauge than 20 AWG.
3 When wiring two or more locks to a single power supply, make sure
that the power rating of the power supply is 1 ½ times greater than
the sum of the lock’s power requirement.

Example
Lock current: 0.169 amp maximum
▲ Total wire run: 1000 feet
▲

Example
For two locks powered by one supply:

Wire gauge needed: 20 AWG two conductor cable

▲

Note: For 12 volt locks, double the maximum lock current, then use
that value on the left side of the chart.

▲

Lock 1 (8K) is rated at 24 volts, 0.18 amps—24 volts × 0.18 amps
= 4.32 volt-amps
Lock 2 (35H) is rated at 24 volts, 0.75 amps—24 volts × 0.75 amps
= 18 volt-amps

Choose a transformer with a rating of at least: (4.32 volt-amps + 18
volt-amps) × 1 ½ = 33.48 volt-amps
