2. OPERATING
INSTRUCTIONS
On receipt of your new Bright instrument, please refer to section 1.1 (Receipt and Unpacking)
and section 1.2 (Assembly and Installation).
As part of its policy of continual improvement, Bright Instrument Company Limited, reserves
the right to incorporate changes, or make additions to, without prior notice. There may,
therefore, be minor details differences between the information in this manual and your
instrument. These differences will not affect the safety and use of the instrument.
Refer to Figure One.
2.1 Operating
handle
(3)
Semi automatic advance – when pushed towards the knife the sledge will move along the
runners and will also advance the specimen the selected amount (thickness). When pulled
back the specimen retraction mechanism is activated.
2.2
Thickness control (5)
A knob, calibrated in microns, is used to select the thickness of sections to be cut from 1µm –
40µm, in 1µm steps. Always set the thickness by turning the knob anticlockwise. If the
thickness has to be reduced then turn clockwise past the required thickness, then
anticlockwise.
2.3
Coarse advance/trim control (4)
Quickly raises or lowers the specimen 450µm per turn. As this control is always engaged, it
can be used at any time.
2.4 Specimen
holder
Specimens are clamped in the vice (7) or alternative holder if fitted. The specimen holder can
be raised and lowered after releasing the clamp lever (14).
2.5 Knife
clamps
Two screws, turned by a lever (10), are used to fix the knife in the knife clamp and the knife
clamp in the knife block (9). The cutting angle of the knife is adjustable from 0-40º. A scale is
provided on the knife block. Slew angles of the knife can be obtained by loosening the knife
block clamp levers (12) and the knife clamp levers (10) and moving knife to slew angle
required.
2.6 Knife
guards
Each knife guard (1) can be moved to the central position to cover the working area of the
knife, or to the outer position while section cutting. The black knobs secure the guards in the
chosen position.
2.7
Side pillars [Fig.1 20 & 23]
In normal use, these pillars slope inwards slightly. For large area sections they can be
unbolted from the base, swapped left to right and refitted, so that they slop outwards, so
providing more space.
