Installing Rotary Microtome Accessories
Step 1. Install the removeable waste tray
After unpacking the removable waste tray, slide it onto the base of the RF-800 rotary microtome from the
front. The grooves in the removable waste tray will fit perfectly into the underside of the microtome base.
Make sure that the waste tray is secure after installation.

12
Step 2. Learn the different components of the knife holder base
The knife holder base is composed of three (3) separate components that interlock together:
Starting from the bottom-most piece, here is what each component does:
Knife Holder Base Component
Movement & Function
Base Component
The base component has a groove opening
on the bottom that allows it to slide onto the
microtome unit.
The handle on the right side of the base
component allows the angle of the knife
holder base to be adjusted for cutting.
Middle Component
The middle component allows for horizontal
(or lateral) movement of the cutting stage.
This is advantageous because it allows
users to be able to access the entire length
of the microtome cutting blade during
slicing.
The handle on the left side allows the
cutting stage to be moved horizontally.
Top Component (Cutting Stage & Blade
Holder)
The top component functions as a cutting
stage for collecting sectioned tissue slices.
It also contains the knife blade holder.
We include two cutting blade safety
features on the top component:
1. Blade guard: This guard covers the
entire length of the cutting blade, to
protect users.
2. Blade ejector: This piece helps eject
the cutting blade for easy removal.

13
Step 3. Install the knife holder base onto the microtome base unit
Match the grooves on the microtome base (2 and 3 in the image below) to the openings on the
knife holder base (green arrows). Once the knife holder base is installed, lock it securely in
place by turning the handle (1).
Cutting Sections with the Rotary Microtome
This section covers the operational procedures of the Precisionary Rotary Microtome RF-800.
Step 1. Insert a cassette or tissue block into the specimen head clamp
Begin by pushing the specimen clamp lever towards you, then insert the cassette block. Once
your cassette is inserted, let go of the specimen clamp lever. The cassette will be securely and
firmly held in place, ready for cutting.
Always remember to wear safety gloves while operating the instrument.

14
Step 2. Adjust the orientation angles of the specimen head
To adjust the angle of the specimen head holding your specimen:
• Vertical angle adjustment (north-south axis or Y-axis): Loosen the Specimen Head
Rotation Locking Lever (1), and adjust the orientation using the top knob (2) to your
desired angle.
• Horizontal angle adjustment (left-right axis or X-axis): Loosen the Specimen Head
Rotation Locking Lever (1), and adjust the orientation using the side knob (3) to your
desired angle.
Step 3. Insert a rotary microtome cutting blade
First, loosen the clamping knob (green arrow) for the top component of the knife block set to
insert a microtome cutting blade. Then tighten the clamping knob. You can choose to use either
low-profile or high-profile cutting blades with the RF-800 rotary microtome.
We include two cutting blade safety features on the top component:
1. Blade guard (blue arrow): This guard covers the entire length of the cutting blade, to
protect users.
2. Blade ejector (red arrow): This piece helps eject the cutting blade for easy removal.

15
Please note the safety guards located on the knife holder.
Microtome knives
• Take extreme caution when handling microtome knives/disposable blades as
mishandling sharp objects may cause serious injury.
• Remember to always keep knives/disposable blades accounted for in secured areas.
• Never place a knife/disposable blade on a surface with its cutting edge facing upward.
• Do not attempt to catch a falling knife/disposable blade.
• Always remember to lock the handwheel and ensure that the knife/disposable blade is
covered by the safety guard before handling or changing the specimen.
Always remember to wear safety gloves while operating the instrument.

Cleaning & Maintenance
Cleaning & Disinfecting
The RF-800 has been designed to facilitate easy cleaning. Upkeeping the proper maintenance
and cleaning of your instrument is essential in reducing machine degradation.
The section waste can easily be removed by taking out the debris collection tray and disposing
the section waste into a biohazard bin.
We recommend cleaning the RF-800 with isopropyl alcohol (70%).
• Do NOT use xylene, scouring powders or solvents containing acetone or xylene.
• Do NOT use bleach.
• These chemicals will damage the finished surfaces of the RF-800 rotary microtome.
Allow the RF-800 rotary microtome to completely dry before using it again.
To remove paraffin residue, you may use removers such as PARAGardTM Paraffin Repellant.
Remove paraffin residues with a dry cloth or paper towel.
Personal protective wear such as gloves and mask should be worn throughout this
process. Safety precautions for all disinfecting solutions are provided by the
manufacturer and should be followed.
It is important that all sectioning waste is removed BEFORE proceeding to section a
new sample. All waste MUST be removed after each specimen is sectioned.

Troubleshooting
Are you the proud owner of a Precisionary Instruments Rotary Microtome RF-800, but are
having problems? This is our “Troubleshooting Guide,” which we wrote to help you troubleshoot
the most commonly encountered issues. Jump right in!
Problem
Solution
Thick & thin alternating tissue
sections
Make sure that the blade holder is clamping the cutting knife
tightly.
Make sure that the specimen in the cassette is clamped to the
specimen head clamp tightly.
If clamping the cassette is difficult, remove the specimen clamp
holder and clean any paraffin residue.
Tissue sections are compressed or
folded
Change to a new knife blade. Typically, this occurs when the
blade is dull.
Also try slowing down the sectioning speed. A cutting speed that
is too fast can cause compressed or folded sections.
Tissue sections have “stripes” or
smears
This results from an accumulation of paraffin debris. Using a
tissue, wipe and clean the cutting blade. Or, change to a new
cutting blade.
You can also try adjusting the clearance angle.
The specimen head cannot move
forward
You have likely reached the front-end position of the travel
distance of the specimen head. Use the coarse feed wheel to fast
reverse the specimen head to its original back position.
Cut tissues sections are curling
and not forming a “ribbon”
Your section thickness may be too thick because you are still
trimming. Try decreasing the section thickness.
The angle of knife clearance may be too small. Increase the
clearance angle to 3-8 degrees.
Your knife may be too dull, so change to a new cutting blade.
After turning on the rotary
microtome, the LCD screen is off
This results from a damaged power cord or fuse. Contact
Precisionary Instruments for ordering a replacement power cord
and/or instructions on replacing the fuse.
