Featuresfeatures:large-volumeremovablewaste tray on the top of housing, convenient to use.imported cross-roller guide rails andhigh-precision screw motion mechanism fast switching between paraffin block clamp and cassette clamp;the red bar on the blade holder covers the whole length of blade to protect the user and enables easy changing of the blade;hand-wheel balance can be is precisely adjustedand can be locked at any position, ensuring safetyand convenience of sectioningblade holder can be laterally movedwithout direct contact, enabling use of the entire length of the blade. (three different segments)automatic sectioning speed is adjustable (bk-mt398a only) auto slicing controller ensures trimming and slicing switching easily; when it is off, semi-auto slicing or trimming is available; (bk-mt398a only)safety and emergency braking systemssecurity alarm systems, driver-overload protection and auto-sleep protection system; (bk-mt398a only)control system with 3 modes: conventional mode, intelligence sensing mode and whole layer cutting mode;(bk-mt390s only) technical parameters:modelbk-mt398abk-mt390sbk-mt358smodeautomatic or manual mode without intelligent sensingsemi-automatic with intelligent sensingsemi-automatic without intelligent sensingfunctionsectioning, trimming, fast forward, fast backward, quick conversion; automatic retraction (except bk-mt358s).Retraction range0-50m ( if 0 is set, retraction function is off )5-50 (retraction distance is optional in this range, and increment is 5m, such as, 5, 10, 15, 25.) displayled display:sectioning thickness, trimming thickness, slice count, slice speed.
