if any, to your distributor. Do not discard shipping
materials until Notcher is set up and running properly.
Compare contents of shipping carton with the contents
list above. Report shortages, if any, to your distributor.
The Abrasive Notcher should be located on a sturdy,
level floor in a dry environment, with good overhead
lighting and room enough for loading and offloading of
stock, and general maintenance.
Lift machine using hook or straps through lifting plate
(Figure 5-1). Make sure lifting equipment capacity
exceeds maximum weight of Notcher.
Machine is heavy; use appropriate
lifting device and exercise caution when moving to
final location. Failure to comply may cause serious
injury.

It is recommended that Notcher be bolted to floor, using
lag screws or similar means. See mounting pattern,
Fig.3
Fig 3
Remove rust protectant from exposed surfaces with a
clean rag and cleaner/degreaser or kerosene. Avoid
getting solvents on rubber or plastic parts.
5.2 Mains connection
Mains connection and any extension cords used must
comply with applicable regulations.
The mains voltage must comply with the information on
the machine licence plate.
The mains connection must have a 10A surge-proof
fuse.

The red OFF-button on the main switch ( Fig 4) stops
the machine.
Belt grinder is consisted of main body and its racks. The
main body can swivel and be adjusted in a certain angle
range around the racks. It is in operation by a grinding
wheel which is directly driven by a motor.
5.4 Connection of dust collection
Fig 4
Connect back dust collection outlet to dust extrusion
system.
Connect front dust collection outlet to proper container
or bag. When dust in the bag is more the half of the
capacity of the collection bag, please stop the
machining process and clean the bag in time. (D, Fig.4)
6. Setup and adjustments
Disconnect machine from power
source before making adjustments, unless
indicated otherwise.
6.1 Dust and chip collection
The chip boxes (see F, Fig 5) are located to catch
swarf/chips at point of workpiece contact. The box near
the jaw assembly freely slides in and out; the box
beneath the wheel grinder is secured by a screw.
The circular plate at bottom of each chip box can be
removed to connect a dust collection hose using a hose
clamp. It is strongly recommended that a dust collection
system (not provided) suitable for metal working be
used with the Notcher.
6.2 Jaw adjustments
See Fig5.
Handle (A) –Moves jaw assembly toward and away
from belt. Adjust handle sensitivity using the socket
head screws underneath handle.
Locking lever (B) –Push to right to lock lateral slide; left
to unlock.
Handle (C) –Rotate to move floating jaw.
Angle locking screw (D) –Loosen to rotate jaw
assembly for angular work. Refer to adjoining angle
scale. Always tighten screw before operating.
