3. UNPACKING
Carefully inspect the exterior of the packing box. Any visible damage should immediately be
reported to Fire Pants Fabrication. Remove all packing documents from the interior of the box and
file in your records. Remove the shipping box, the foam packaging material, and the Scorpion
Grinder. Open the top flaps of the packing box to remove the Scorpion Grinder from the base of the
box. Grasp the Scorpion Grinder on both sides, using proper lifting techniques, and place it on a
stable bench top. Visually check the Scorpion Grinder to ensure that no damage occurred during
shipping.
4. SETTING UP
Tools required:
5mm Allen key
6mm Allen key
10mm spanner (or socket) x2
13mm spanner (or socket)
16mm spanner (or socket)
17mm spanner (or socket)
18mm spanner (or socket)
Combination square or small spirit level
Torque wrench (recommended)

5
Step 1
Unpack the contents of all packages.
One package will contain the grinder frame
and parts, the other will have the motor
and VSD / Switchgear (if applicable).
First find the bag of bolts and confirm the
contents.
Refer to contents list on bag for correct
hardware.
Step 2
Unpack motor onto bench, flip it onto its
back, use a 13mm socket to remove the
motor feet. Retain feet and hardware.
Step 3
Place motor in position shown in picture,
Reinstall the feet using the original
hardware on the side facing up. The feet
will be on the same side as the data plate.
Tighten to 15 ft/lb

6
*You may have to clean the paint on the
bolt head if it does not seat fully into its
position.
Step 3.1
To allow the base to bolt down properly,
use a #2 Philips screwdriver to:
For Fixed speed machines: swap bolts A
and B.
For Variable speed machines: remove bolt
A and place in the empty position B.
Step 4
While in this position, locate the base
plate, and the 4 x M8*40mm countersunk
bolts, washers and nuts. Use a 6mm allen
key and 13mm spanner and 5mm Allen key
to install the base plate. (If installing on a
pedestal, you may need to preinstall the
bolts).

7
Step 5
Place motor on its feet as shown, at this
point you should secure the grinder on a
bench or pedestal where it will be used. Do
NOT connect the motor to a power until
the assembly is completed.
Step 6
locate the 4 x M8*25mm bolts, Large
washers, Scorpion frame.
Step 7
Place the frame on the motor face mount
in an upright position, install the 4 bolts by
hand into the slotted holes into the motor
face. Use a spirit level on the front vertical
face of the frame and adjust plumb before
tightening to 20 ft/lb with 13mm socket.

8
Step 8
Use the 6 x M6x40 bolts, washers, flange
nuts, and nyloc nut to assemble the tool
holder.
Assemble as shown, with the nyloc nut
closest to the M12 threaded hole in the
frame. Align the flats of the nut
horizontally to allow the platen bracket to
slide over it.
Step 8.1
Install one of the locking handles to the
tool holder.
Use an Allen key in the back, while pulling
the lever back to allow you to rotate the
centre easily.
Step 9
Locate the platen, angle brackets, 2 x
10*16mm bolts & washers, 2 x M12*20mm
bolts & washers.
Install angle brackets to platen by hand,
then the assembly to the frame. Lightly nip
up the bolts using a 16mm and 18mm
spanner to hold in place, final adjustment
will come later.
The platen mount holes are offset, the
default position is to have the ‘Long’ end
down (as shown), but it can be reversed to
give more platen above the work rest, and
a shorter ‘Slack’ belt area.

9
Step 10
Next assemble the work rest to the tool
arm using 1 x M12*35mm bolt and washer
and 1 locking handle with a washer.
Tighten the bolt just enough to allow some
movement when the locking handle has
been released.

10
Step
10.1
Install tool arm to the frame by sliding the
tool arm into the slot. Tighten with the
locking handle on the side.
*The angle of the locking handles can be
adjusted by pulling the handle out and
rotating to another position. The spring will
lock them in the new position.
Step 11
Locate the tensioner handle, hinge
assembly, tracking adjuster, tracking wheel
(125mm), 2 x M8*25mm Socket head bolt,
1 x M8*20mm socket head bolt.
Step 12
Place the two (2) 25mm long bolts through
the holes shown, and place through the
holes on the tracking arm, then secure the
hinge assembly to the other side. Tighten
to 20 ft/lb.

11
Step 13
Install the M10 Nut on the T handle thread,
then install the tracking adjuster T handle
until it contacts the back of the hinge.
*the nut is there to help lock the handle in
place, it should not need a spanner to
tighten it enough to lock the adjuster in
place.

12
Step 14
Locate the gas strut, Install the balls onto
the frame and tensioner as shown, with a
M8 washer under each.
Remove the locking clip from the gas strut
(if required) and press the ends firmly onto
the mounts on the frame. The rod should
be facing down. Replace clips.
Step 15
Then slide the tracking wheel over the axle
on the hinge assembly. You may need to
use a small screwdriver to lift the bearing
spacer inside the wheel to get it to slide on.
Secure using the 20mm long socket head
bolt and washer, tighten to 20ft/lb.

13
Step
15.1
Locate the guard, M10 x 35mm bolt, 2 x
M10 washers, and M10 Nyloc Nut.
Install guard on tensioner arm as shown.
Tighten nut and bolt enough to be able to
rotate the guard by hand, but not so loose
that is moves on its own.
The guard can be lifted up out of the way
for belt changes, but should always be in
the down position while the grinder is in
use.
(Guard is not shown in the following steps)
Step 16
Locate the drive wheel, and M8*40mm
bolt. Remove the protective cover from the
motor shaft, line up the keyway on the
shaft and the wheel, carefully slide the
drive wheel onto the shaft.
The wheel should be snug, but not require
any more than some light taps with a
rubber hammer to slide it on.
If it does not slide on, remove the key from
the shaft, and using some fine emery
gently work around the shaft to remove
any high spots. If it still does not slide on,
contact Fire Pants Fab for further
instructions.

14
Step 17
Once the wheel is seated on the shaft,
secure with the bolt, tighten to 20ft/lb.
Step 18
Locate the supplied belt and hang it over
the top wheel. Pull down on the tensioner
handle to hook it under the drive wheel.
Pay attention to the belt orientation, some
can only be used in one direction.

15
Step 19
Rotate the belt by hand in an anticlockwise
direction (viewed from the drive wheel
end), while using the tracking adjuster
handle to align the belt as close to centre
as possible on both wheels.
Step 20
Once the belt is aligned, adjust the platen
fore/aft position by loosening the M12
bolts on the frame, the platen should
protrude into the belt by 1-2mm. Use a
spirit level or measure off the frame to get
it even. Tighten adjuster bolts.
Adjust the platen left or right to be centred
on the belt by loosening the M10 bolts on
the back of the platen. Tighten adjuster
bolts.
Adjust the platen left or right to be centred
on the belt by loosening the M10 bolts on
the back of the platen. Tighten adjuster
bolts.

16
Step 21
Use a square to adjust the worktable, set it
to 90° to the platen. Remember to tighten
both work rest locks before loosening or
tightening the worktable.
Step 22
Mount the VSD / DOL Starter securely.
Follow the instructions in the VSD manual
for air gap and other mounting
requirements.
Mounting hardware not included.
Step 23
Your Scorpion grinder is now assembled
and ready to use. Plug it in to a suitable
power source and refer to the Operating
instruction section.
