The tool works in all positions, horizontal or vertical.
Cutter/spreader head rotates freely though 360° (fig. 3) to allow best
possible working position at all times. NOTE! To rotate the head the con-
trol knob has to be set in neutral position (see Tool operation).
Safety features
The tool is equipped with an integral safety valve that protects it against
overloading. The safety valve is factory-set for a maximum working pres-
sure.
Tool operation (Fig. 4 & 5)
The tool is operated by means of the pump lever and a control knob. The
control knob has three settings, one for opening and one for closing the
blades/arms, plus a neutral setting.
Opening the blades/arms (Spread/Lift)
- Turn the knob to setting according to Fig. 4.1
- Operate the pump lever (Fig. 5)
- The blades/arms should open
Closing the blades/arms (Cutt/Squeez)
- Turn the knob to setting according to Fig. 4.3
- Operate the pump lever (Fig. 5)
- The blades/arms should close
Neutral setting
Turn the knob to setting according to Fig. 4.2
NOTE! The tool is not equipped with a hold function. A lifted load
will sink during the time the control knob is turned between the
outer positions.

Practical work
Cutting
Before cutting we recommend that the tips are removed from the tool.
To avoid losing the hinge pins you can place them in the holes in the tips
(Fig. 6).
Always strive to cut at right angles to the cutting object.
When cutting, check that the shears are not tending to come apart
(Fig. 7).
Lifting
Always strive to get the tool operating at right angles to the object.
If the tool starts to twist - stop the operation ! Get a new grip and try
again.
If the tool has started to twist, it never becomes better, but always worse.
A usual cause for the tool to twist is that the load is gliding sideways.
Therefore always secure the load before starting the operation.
Never work under a raised load without first securing it by
support blocks or other mechanical support.
Bending – Spreading
Always strive to get the load as far as possible into the tips to avoid the
tips loosing their grip. Also consider the possibility to turn one or both tips
for better grip (Fig. 8).
If the tool has started to twist, it never becomes better, but always worse
Crushing
When crushing, it is important that the arms (shears) do not tend to
diverge sideways. If this occurs - stop the operation ! Get a new grip and
try again.
When work is completed
Pump the blades/arms together to the halfway position, not fully open
and not fully closed. Turn the control knob to the neutral setting. Store
the tool like this.
Safety
•
Always use personal protection equipment, covering overall, helmet
with visor or protective goggles, gloves etc.
•
Beware of the risk of sparks if electric wires are cut off. Always start
the work by ensuring that the object is not connected to any electric
source.
•
Always be careful when cutting off springs or spring mountings.
They are often prestressed and may cause damage when cut.
