ing grease, lower the threaded push rod adjustment screw shown in Figure 24. Repeat the
adjustment, a little at a time, until the driving bands are sized and all the grooves between
them are properly filled with lubricant.
Care should be used when adjusting depth to insure that the lube does not run over onto the
nose of the bullet. When the setting is correct, tighten the adjusting screw lock nut and pro-
ceed with your sizing and lubricating.
Note: Do not operate in cold weather or until lubricant has been allowed to reach room
temperature of approximately 70 degrees.
Attaching Gas Checks
You may attach gas checks to your bullets while sizing and lubricating. Simply set the gas
check (cup end up) in the center of the sizing die and place your bullet over it as you pull
down the operating handle. Firm pressure at the bottom of the stroke will usually seat your
gas check firmly and evenly.
However, if the gas check will not fully seat on the bullet using only finger pressure, the
Lyman Gascheck Seater should be employed for best results.
To install, raise the #4500’s push rod until its top bears against the bottom of the sizing die.
Then slip the Gascheck Seater around the threaded pushrod adjusting screw so that the push
rod is held at the base of the sizing die.
Next, a gascheck is set, cup-side up, in the center of the sizing die and a bullet guided into it as
you pull down on the operating handle. Use only enough force to fully seat the gascheck. After
all the gaschecks have been installed, remove the Seater and size and lubricate normally.
Use of the Gascheck Seater ensures the squarest-possible bullet base regardless of the type
of gaschecks used. A good square bullet base translates into improved accuracy.
The Lyman #4500 Lubricator/Sizer utilizes an 110V or 220V 20 watt heating element to
allow easy use of “hard” lubes such as Lyman’s Orange Magic. The element is inserted in
the bottom, rear portion of the #4500 (see Figure #25) and is secured with a 10-32 size allen
screw.
Caution: Do not over tighten the allen screw. Do not operate heater if not installed into the
lubricator/sizer and securely locked in place. Burns can result if operated out of the unit.
Once secured in place, plug in element to a properly grounded outlet for 20-30 minutes
before beginning to size bullets. The body of the #4500 should be warm to touch when at
proper operating temperatures. Should the bullet lube become too soft, the unit can be
unplugged. Once unplugged, the cast iron body of the #4500 will retain its heat for a period
of approximately one hour.
See Page 71 for "Tips"
Caution: Do not leave unattended while plugged in.
