3.
The V-belts tighten uniformly because of the
idler pulley. Rotate the adjustment bolt until
the V-belt has approximately
when moderate pressure is applied midway
between the pulleys (see Figure 49), then
re-tighten the jam nut and close the V-belt
cover.

Replacing V-Belts
Replacement V-belt part numbers can be found
in the back of this manual in the PARTS section,
beginning on Page 45.
To remove and replace V-belts:
1.
DISCONNECT MACHINE FROM POWER!
2.
Open the V-belt cover.
3.
Loosen the adjustment bolt jam nut near
the motor (see Figure 48) and push motor
toward machine to loosen V-belts.
4.
Remove belt(s) from pulleys.
5.
Install new V-belt(s) according to desired
spindle speed (see Setting Spindle Speed
on Page 29).
6.

Machine Storage
The machine must be properly prepared if it will
be stored for any period of time. Doing this will
help prevent the development of rust and corro-
sion and ensure the mill remains in good condition
for later use.
Note: When taking the machine out of storage,
repeat the Test Run and the Spindle Break-In.
Preparing Mill for Storage
1.
DISCONNECT MACHINE FROM POWER!
2.
Lubricate machine as directed in Lubrication
on Page 33.
3.
Thoroughly clean all unpainted, bare metal
surfaces, then coat them with quality rust pre-
ventative. Take care to ensure these surfaces
are completely covered but rust preventative
is kept off painted surfaces.
Note: If the machine will be out of service
for only a short period of time, use way oil in
place of rust preventative.
4.
Loosen belts to prevent them from stretching
during storage. Post a reminder on machine
that belts need to be re-installed or tensioned
before resuming operations.
5.
Cover and place machine in a dry area that
is out of direct sunlight and away from haz-
ardous fumes, paint, solvents, or gas. Fumes
and sunlight can bleach or discolor paint and
plastic parts.
6.
At least once a month, start the mill and run
all gear-driven components for a few min-
utes. This will keep the bearings, bushings,
gears, and shafts well lubricated and pro-
tected from corrosion, especially during the
winter months.
Bringing Mill Out of Storage
1.
Re-tension V-belts (refer to Page 35) if you
loosened them for storage purposes.
2.
Repeat Test Run and Spindle Break-In pro-
cedures, beginning on Page 21.
