5.3 General hints of handling
Adopt a safe and stable stance before attempting the use the machine.
Remember: do not use the machine to help maintain your balance, as is done when using a
hand-held circular saw. This will twist the blades and cause them to separate and possibly
jam the machine.
Think for a few moments about where you want to make the cut and how long the first cut
should be. Discuss this with other members of the team.
Avoid cutting through bolts, pins, safety-belt mounting points, arrestor units, etc. as far as
possible. This places much greater stress on the cutting edges and can result in chipped and
broken teeth.
Sparking tends to increase as the blades become worn. If there is a high level of sparking
when cutting light metal plate the saw-blades should be examined. Worn blades will usually
reduce the cutting performance of the machine.
Remember that saw chips are ejected form both sides of the machine. Warn other members
of the team to stay out of range of flying chips.
The machine can cut backwards as well as forwards!Use this advantage to good effect.
You will have more energy at the beginning of the cutting operation than at the end. When
cutting into a car bonnet, for example, start off as far out as possible and bring the saw back
towards you. Do not use these saws for medium-duty cutting/rescue/salvage work. It is more
efficient to use other power tools to cut into flat surfaces and make longer cuts. Use the saw
to cut away panels and covers to provide access for heavy-duty equipment such as cylinder
cutters and shears. Cut slowly when the material contains bolts or rivets.
If increased resistance is encountered when performing dismantling or rescue/salvage work
the cut should be re-started. Cut slowly and steadily, as when using domestic DIY tools. This
will help save on blades and give you many years of enjoyment from your machine.
5.4 The cutting
Ask your distributor for our special schematic course tabulars. They offer in a very clear form
the main advices for the cutting. Here in short words:
1.
Always cut in a modus of PUSH AND RELEASE:
a.
at cutting into surfaces
b.
at cutting in massive materials
c.
at cutting in thin metal sheets
With this handling you make sure the best performance in cutting. Additionally this will
give you a long life eather for the saw and for for the saw blades.
2.
When cutting in an angle to the surface, keep the saw tight. Be aware that the saw
is working with only one blade in the first moment. So there will be a reaction.
When the second blade has entered the material, the reaction will vanish and you
will cut reaction free. Do not forget the short release after etering the material.
3.
Lubrication is needed at any material and any kind of cutting. It reduces the
grinding between the saw blades and offers you an even colder cut. It is sufficient
to press the button at the top of the handle for only 2-3 times before normal
material cutting operations. Soapy material like tar or aluminum needs permanent
lubricant between the blades. Ohterwise the blades will be damaged!
For more than 95% of rescue operation your normal set will offer you a very handsome and
uncomplicated handling. Enjoy the high speed of ultrasharp and cold cutting without too
much concnetration on the machine itself. With a little practice and experience the saw will
be like your prolongered arm.
