4. Functional description
4.1 Description
The cutting and spreading tool StrongArm™ e100/le100 has been designed in such a way
that a hydraulically operated piston activates mechanical joints symmetrically to open or
close a set of two opposing tool arms, thus enabling objects to be cut or spread.
Additionally, door opener tool tips especially designed for that purpose can be positioned in
very narrow gaps or cracks to spread them apart.
For all devices, the movement is activated by means of a valve in the form of a star grip.
All devices employee a deadman switch and full load-supporting function when the star grip
is released.
The StrongArm™ e100/le100 device does not need to be connected to an external hydraulic
source (e.g. a motor pump). Generation of the required hydraulic pressure takes place within
the body of the device.
A rechargeable battery serves as drive and energy source.
The accumulator battery can be inserted into the opening provided in the body of the tool.
It is then automatically locked into position.
You can extend the operating time of your device by using several batteries. The batteries
can be recharged after use, using the external charger.
A universal accessory rail is mounted to the top of the StrongArm™ to allow optional equip-
ment to be mounted to the tool. For example, a Àashlight can be mounted to facilite work
being done under poor lighting conditions.
There is an illuminated ring around the switch on the e100 (blue) StrongArm™ tool to in-
dicate the tool is on and ready for operation. The le100 (black) StrongArm™ tool does not
have this feature in order to keep visibility low.
Another indicator that either tool is ready for operation is that that the switch is recessed
when it is “on”. This also prevents accidental activation.
