RCBS 98941 Product Instructions page 4

PRIMERS AND POWDER
• Store powder beyond the reach of children and away from heat, dampness, open flames and
electrical equipment. Avoid areas where static electricity is evident.
• DO NOT have more than one can of powder on the bench at one time. Powder cans should be
stored away from the bench to avoid picking up the wrong one.
• DO NOT use any powder unless its identity is positively known. The only positive identification
is the manufacturer's label on the original canister. Discard all mixed powders and those of
uncertain identity.
• DO NOT store powder in the unit after a reloading session. Over time the powder will damage
the powder hopper.
LOADING DATA
• DO NOT SMOKE WHILE RELOADING
• OBSERVE ALL WARNINGS ABOUT THE USE OF MAXIMUM LISTED LOADS.
• Use only laboratory tested reloading data. We recommend the SPEER Reloading Manual.
WARNING
This digital scale is for use with smokeless powders only. Do not use with black powder (used
in muzzle loading firearms). If black powder should come in contact with an electrical spark, an
explosion may occur, resulting in serious injury or death.
CALIBRATION
Calibration should be performed before every use. Prior to calibration, scale should be turned on
and allowed to warm up for at least 15-20 minutes. The warm up process should be performed prior
to every use if scale has been off for more than 30 minutes. Calibration is performed WITHOUT scale
pan on the platen. To calibrate correctly, follow the CALIBRATION section of this instruction manual.
A scale with improper calibration will cause an incorrect charge weight which may exceed the
maximum recommended load. Re-check frequently during use with the calibration weights provided.
If accuracy is found to be out of tolerance, the scale must be recalibrated.
PRECAUTIONS
Digital scales are very reliable devices. However, here are some events which may result in an
inaccurate reading:
• Change in temperature. If the temperature changes more than 40
the scale. Allow scale to stabilize for 15-20 minutes prior to use.
• Changes in scale location or an uneven working surface which is not level. Use level bubble to
check working surface.
• Wind makes scales unstable. Use wind cover only if in area where there is an air current that can
not be controlled, especially in Match mode.
• Off center placement of weight on the platen. Ensure weight is placed in center of platen.
• Movement of the scale during operation.
• Unfilled dispense tube. After initial set up dispense one charge of 60gn to ensure the dispense
tubes are filled with powder, to avoid over/under dispense charges.
• Use only the two calibration weights supplied for accuracy.
• Calibration weight accuracy is crucial. Keep weights clean and carefully stored. If dropped or
damaged, have weights inspected against known standards. Contact RCBS Customer Service.
• Static electricity can cause erratic behavior in the scale, causing weight being displayed to
change frequently. If static build-up is evident, wipe scale with an anti-static sheet, or use anti-
static spray. Spray on clean soft cloth first. Do not allow spray to get into mechanism.
