General Maintenance
All moving parts need to be lubricated and oiled from time to time. Before lubricating these parts the system
should be cleaned from dust, debris and any oil and grease.
All moving parts attached with screws need to be checked to ensure these are fastened securely. Some screws may
loosen in transit. It is advised that all screws are re-checked and re-tightened after around 200 cuts. Maintaining
the system correctly will help avoid faults and damage.
After unpacking the Trimfast Ream Cutter, check to make sure that there is no damage.

Ream Cutter Components
(Based on RE3946 Ream Cutter - All components are similar but on some models the spindle guided clamping wheel may be
replaced with a clamping lever).

6
• SafetyGadget - This is to protect ngers whilst operating the cutter.
• KnifeLever - The knife lever enables cutting without eort. A sharp knife is important for the
best performance. After each cutting operation the knife lever must be placed back into its top position
until the knife lever is locked.
• KnifeLockingDevice- This secures the knife in its top, raised position. A cutting operation
can only be carried out when the front safety guard is in the down position and the locking device is
released. Please note the knife locking device is controlled and connected with the front safety guard
and the knife lever. You can open the front safety guard only when the knife lever is in its starting point.
• Blade - Made of high quality carbon steel, the blade is resharpenable.
• BladeCarrier - Attached to the system are a number of screws. Only disassemble these for a
knife change or when carrying out maintenance on the system.

• Release the hand lever of the ick action clamping system. Lift the hand guard, and remove the paper
pile from the cutter.
Cutting Stick
If the last sheet of the paper pile does not cut through, even though the knife adjustment has already been
adjusted, the cutting stick should be changed or rotated.
The cutting stick can be used twice on each side, which means you can rotate each stick 8 times.
The cutting stick ts into the system table and can be lifted out using a screw driver. The pins in the base of the
systems table hold the cutting sticks, by securing the holes on each end of the stick onto the pins.
Please note. When the cutting stick is changed, the knife has to be readjusted. A knife which cuts too deeply
damages not only the cutting stick but also the knife too.

10
Blade Resharpening
Please note: A dull knife does not cut accurately. The cutting of thicker stock paper or cardboard, will blunt the
blade easily. When the knife cannot cut the paper pile cleanly even when the cutting stick has been changed and
the knife adjustment has been done, then the blade is required to be resharpened. When you need to resharpen
the blade, take the blade to be resharpened and then refer to the ‘Blade Replacement’ section for instructions on
how to reload the blade.
Precise cuts are only possible with a sharp knife. The knife should be changed as soon as the quality and the
accuracy of the cuts are not to the expected standards. If the knife should jam in the paper pile or leave grooves
in the paper, the knife must be changed right away. Knife life with basic paper is approximately 600 cutting times,
depending on the cutting capacity. This will vary depending on the paper stock being cut. The knife should only
be changed by a single person, to avoid injuries. The cutting edge is extremely sharp and must be handled with
care.
