buildup. The selected cutting blade should not be longer than 3/4”
past the thickness of your foam board. The foam cools the blade as
it cuts. The exposed portion can overheat and cause your blade to
warp.
Warning:
Don’t press the trigger for a long time, in order to reduce the heat
transfer from blade to blade holder. High temperature will cause
deformation of the plastic and may cause injury to human body, we
highly recommend when pressing trigger for 15S, please release
it for 30s which will prolong the service life of the product
Caution:
Consult foam manufacturer’s MSDS sheet for flash points and
toxicity of material to be cut.
Always operate the MS-551 Hot Knife in well ventilated
space
Never burn off excess residue on the hot knife blade. The blades
will overheat, warping the blade and potentially overheating the
MS-551 Hot Knife.
Only operate MS-551 Hot Knife when it is in contact with the
insulation board.
Keep hot blades away from skin, clothing and other flammable
materials.
Allow blades to cool before handling. A hot blade may cause
injury or burns to exposed surfaces.
Maintenance
Constant use of the MS-551 Hot Knife may result in polystyrene
material build up on blades and the blade holders. This excess
polystyrene interferes with the proper electrical flow and impairs the
performance of the blades. The blade holders and blades can be
thoroughly cleaned with a wire brush.
