Use clean, dry, oil treated air, regulated between 552 kPa [80 psi] and 689 kPa [100 psi]. It is important that the
air pressure is maintained constantly within the required air pressure range. Pressure lower than stated will be
insufficient for the crimping operation. Pressure higher than stated may cause damage to the tool.
A filter and moisture separator, regulator, and lubricator (customer supplied) must be used with this tool to
ensure dependable performance and long life. It is strongly recommended that the units be installed at each
tool in the order shown in Figure 3. Mount the units as close as possible to the tool, preferably where the tool
hose is connected to the air system. Make sure that the units are checked regularly on an assigned schedule.
Suggested manufacturers and benefits realized by the use of this equipment is given in Figure 3.
Check the air pressure at the tool while the tool is operating.
1. Check the air compressor and air line pressure regulator for sufficient capacity, proper settings, and
mechanical condition.
2. Check for clogged or kinked air lines or hoses.
3. Check the air lines, hoses, and fittings or couplings for correct size (may be too small).
Check the air compressor and air line pressure regulator for proper settings and mechanical condition.
To avoid personal injury or damage to the tool, carefully observe the following safety precautions before and
during operation of the tool.
— ALWAYS disconnect the air supply before changing the jaw assembly or performing any maintenance
on the tool
— ALWAYS keep fingers clear of the jaws when operating the tool
— ALWAYS ensure that the correct type and size terminal or splice is used in the jaw assembly
— ALWAYS ensure that the pivot pins are fully inserted into the jaws
— NEVER operate the tool without the jaw assembly installed; otherwise, damage to the tool could occur
— NEVER allow air pressure to exceed 689 kPa [100 psi]
Figure 3
The tool consists of a housing, handle, and air hose that connects to an air supply. The housing contains the
cylinder, piston, and cam. The front of the housing accepts an interchangeable jaw assembly that is secured to
the housing by two pivot pins. The back of the housing features an identification plate. The handle has a
control button that actuates the tool. Refer to Figure 4.
When the tool is connected to the air supply, air pressure on the return side of the cylinder maintains the piston
and cam in a neutral position and allows the spring–loaded jaws to remain open. Refer to Figure 4, Detail A.
The operator can now position the wire–loaded terminal or splice in the jaws.
When the control button is depressed, full air line pressure is directed into the power side of the cylinder,
closing the jaws to the crimp position. Refer to Figure 4, Detail B.
Releasing the control button allows full air line pressure to enter the return side of the cylinder, returning the
piston and cam to neutral position. The spring–loaded jaws will open and the tool is ready for the next crimping
operation.
