To avoid personal injury, ALWAYS keep fingers

clear of crimping jaws when operating the tool.

Never place anything within the crimping jaws

except terminals and splices.

5.1. Terminal Crimping Procedure

together simultaneously; then position the terminal

in the crimping chamber on the lower jaw, as

shown in Figure 3, Detail A. The terminal is

properly positioned when the back of the terminal

is facing the upper jaw and the wire barrel is

against the locator.

2. After terminal is properly positioned, release

rollers to allow crimping jaws to spring shut,

holding terminal in place.

3. Insert stripped wire into terminal wire barrel until

the end of the conductor butts against the locator.

4. Activate the tool to complete the crimp. Open

crimping jaws by squeezing the rollers together

simultaneously; then remove crimped terminal.
