PROPER USE GUIDELINES
Cumulative Trauma Disorders can result from the prolonged use of manually powered hand tools. Hand tools are intended for occasional use
and low volume applications. A wide selection of powered application equipment for extended-use, production operations is available.
Figure 1
1. INTRODUCTION
Hydraulic Hand Crimping Tool 1490748-1 (Figure 1) is
designed for crimping the terminals and splices in
Figure 2. Read these instructions thoroughly before
using the hand tool.
Figure 2
Dimensions in this instruction sheet are in metric
units [with U.S. customary units in brackets].
Figures and illustrations are for identification only
and are not drawn to scale.
2. DESCRIPTION
The hand tool has a stationary lever and a movable
lever. These levers are compressed to pump hydraulic
fluid behind the ram, moving it forward and thereby
closing the dies. After the crimping is complete, the
movable lever is turned to depress the plunger. The
moving die retracts to its original position, completing
the crimping cycle.
3. DIE INSERTION AND REMOVAL
To avoid damage to the tooling, never operate the
tool with the dies removed. Failure to insert the dies
before operation can result in damage to the "C"-
head or the tool ram.
1. Advance ram slightly to gain access to moving
die release button.
2. Before inserting dies, refer to instruction sheet
packaged with dies for detailed instructions:
insert or remove dies, as necessary, by following
procedures given in the instruction sheet for the
dies.
4. CRIMPING PROCEDURE
1. Strip wires to dimensions specified on the
instructions packaged with dies (see Figure 2).
