Slots
Recess in early handle sets may only have the slots to accommodate a housing clip. Use 42-70-0055 only in this situation.
Slots Dimples
Recess in this handle set design has slots and dimples to secure a housing clip. The 42-70-0055 can be used but the 42-70-0058 is preferred in this situation.
Slots Dimple Tab Cavity Recess in newer handle sets have two slots, a dimple and a tab cavity to accommodate the newer housing clip design.
42-70-0055
Early M12TM Handle Sets utilize Housing Connection Clip No. 42-70-0055. Install this clip design by aligning the side rails of the clip with the two slots in the handle set. Gently push into place with the aid of a small flat blade screwdriver or a similar instrument. Be sure that the clip is properly seated in both slots and that the clip is flush to sub-flush to the end of the handle set. To remove the clip, use the same small flat blade screwdriver or a similar instrument and push the clip out of the handle set. If the clip is loose or will not stay in place, a needle nose pliers can be used to gently bend/pinch the side rails of the clip. If the clip is damaged do not use, replace with a new 42-70-0055 housing clip.
42-70-0058
Updated M12TM Handle Sets utilize Housing Connection Clips No. 42-70-0055 and 42-700058. (The 42-70-0058 is a preferred upgrade). Install this clip design by aligning the side rails of the clip with the two slots in the handle set. Gently push into place with the aid of a small flat blade screwdriver or a similar instrument. Be sure that the clip is properly seated in both slots and that the tab of the clip snaps down in the round dimpled cavity of the handle set. Be sure that the clip is flush to sub-flush to the end of the handle set. To remove the clip, use the same small flat blade screwdriver or a similar instrument and lift up on the clip tab while pushing the clip out of the handle set. Use a needle nose pliers to gently rebend the clip tab if necessary. If the tab on the clip is damaged during this process and is loose or will not stay in place, replace with a new 42-70-0058 clip.
42-70-0058
Newer M12TM Handle Sets utilize Housing Connection Clip No. 42-70-0058. Install this clip design by aligning the side rails of the clip with the two slots in the handle set. Gently push into place with the aid of a small flat blade screwdriver or a similar instrument. Be sure that the clip is properly seated in both slots and that the tab of the clip snaps down in the rectangular cavity of the handle set. Be sure that the clip is flush to sub-flush to the end of the handle set. To remove the clip, use the same small flat blade screwdriver or a similar instrument and lift the clip tab out of the cavity while pushing the clip out of the handle set. Use a needle nose pliers to gently rebend the clip tab if necessary. If the tab on the clip is damaged during this process and is loose or will not stay in place, replace with a new 42-70-0058 clip.

NOTE: It is very important to make sure that wires are tucked down into the left handle halve to avoid wires being pinched when re-assembling tool. Be sure that all elements of the Electronics Assembly (On-Off Switch, PCBA, LED, Terminal Block Connector and Stator) are properly seated into the left handle halve before re-assembly.
When installing the Fwd/Rev Shuttle, be sure to properly capture the slide button of the fwd/rev micro switch on the PCBA with the front cavity of the shuttle. Once in the left handle halve, be careful that no wires interfer with the travel of the Fwd/Rev Shuttle.
