STORAGE AND MAINTENANCE
A. General Information
Proper storage of your Milestone Potato Seed Cutter when not in use will add to the life of your machine and
reduce costly repairs. Wash or steam clean the machine after the cutting season. Soil buildup will rust and
corrode many metal parts. Attention to these areas will pay off in terms of lower maintenance costs and
longevity of your Milestone Cutter.

instructions will help assure safe operation.
1. Short Term
Prior to parking the machine each night, the machine should be cleaned of debris. It should be
lubricated and visually inspected for any repairs that should be made before cutting the next day.
2. Long Term
Wash or steam all foreign matter off and disinfect your Milestone Cutter. Lubricate all chains, bearings
and fittings.
A. Slip Clutches
Cover or remove to prevent moisture from rusting and “freezing” clutches. If clutches are not
removed, back off adjusting bolts all the way.
B. Chain Belts
Belt chain should be removed, rolled loosely and stored on end, indoors, to protect them from
ultra-violet rays, moisture, and cold temperatures if the cutter is not stored indoors.
C. Roller Chain
Thoroughly clean and lubricate progressive roller cutter chain, as well as all other roller chains.
D. Covering
All rubber covered rollers, progressive table, and belts should be covered to protect from ultra-
violet rays and moisture if cutter is not stored indoors.

MILESTONE CUTTER ADJUSTMENT PROCEDURES
•STEP 1 Check bolt on end of coulter shafts (top & bottom) for tightness. Then remove
drive so drums turn freely.
•SETP 2 Line up center of progressive roller pipe shaft with coulter shaft. Raise or
lower coulter to ¼” (top) gap and 1/8” (bottom) gap. Make sure outside coulter blade is
same height as rest of coulter blades. CAUTION – Lowering coulter blades too low may
cause blades to cut progressive rollers.
•STEP 3 Adjust strippers to 3/8” between stripper end and coulter spacers.
12
MILESTONE CUTTER ADJUSTMENT PROCEDURES
•STEP 4 Lower top drum down on each side until a faint ticking is heard by rotating
drum towards hopper. Adjust both sides accordingly, and it is good to double check.
13
MILESTONE CUTTER ADJUSTMENT PROCEDURES
•STEP 5 Find high spot-on bottom drum and turn it to 1 o’clock position. Drop a
measuring tape down through strippers to high spot-on drum. Raise or lower drum to 1-
1/2” from bottom of stripper to high spot-on drum.
•STEP 6 Find high spot-on top drum. Turn high spot-on top drum to 6 o’clock and high
spot-on bottom drum to 12 o’clock. So, the high spots on each drum face each other. Put
drive chain on while drums are in this position.
•STEP 7 Center cross cut knife evenly between both drums.

CUTTER SET UP AND START UP PROCEDURES
**IMPORTANT**
CUTTER ADJUSTMENT PROCEDURES MUST BE COMPLETED FIRST
(ALL 7 STEPS)
SETTING UP CUTTER
1. Position Cutter - Confirm the following:
•
Make sure all guards are in place
•
The cutter is level from side to side.
•
Inspection table is accessible on both sides of machine
•
Everything is free from rubbing on the belts
•
Position duster (remember duster turns counter clockwise, therefore the duster must be
a little off center, towards opposite side of duster control.)
2. Ensure the coulter blades are the same distance from the back upright angle.
3. Switch on power disconnect on cutter, but do not turn the cutter on.
•
Confirm that all three lights (yellow, green and red) are lit up on the electric eye.
If
not, check and see if all the E-stops are pulled out (1 on power box and 2 up by top of
hopper. and Confirm that the coulter kill switch is attached
)
Electric Eye
Yellow---power to eye
Green--- has small amount reflection.
Red ------ has excess amount of reflection.
If there is a green light but no red, wipe off the reflector and twist the electric eye until
red appears. You can aim it by seeing red in the reflector.
4. Make sure machine is running in the right direction by switching on power supply only to
hopper/conveyors. If not running the right direction, switch line 1 and line 3 (3 phase only) in
electrical disconnect on side of electrical panel. Slow down elevator and close top sizer half
way and bottom sizer most of the way, and pre-sizer all the way.
NOW YOU'RE READY TO RUN
5. MAKE SURE NO ONE IS IN THE MACHINE
Switch on power to the entire cutter
•
Buzzer should sound.
•
Make sure the machine is running smoothly.
•
Slowly add potatoes to machine. For now, keep elevator running slow.
•
Adjust top sizer to where 7 oz. potatoes are on top and 6 oz. potatoes are on the
bottom.
15
6. Adjust the bottom sizer, drop out those potatoes which you would not like to cut in half.
7. Check the cross cut knife and make sure you are cutting the potatoes in the middle. To do
this:
•
Catch a top and bottom of the same potato and determine if they are both even.
•
Adjust by raising or lowering each side.
•
Be patient and take your time.
This is important!
8. Go to the back of cutter and take a sample. Refer to sample taking. (See Page 38)
•
Let your sample determine what adjustments need to be made.
•
Adjust cutter according to sample taking instructions.
•
Make sure those on the inspection table, cutting by hand are educated in what their
jobs are. They can change a sample if not.
9. Check the trim rollers and see what waste you are creating. You can make adjustments to
control the waste by following steps 5-8.
•
If the pieces being cut by the cross cut knife are falling through the trim rollers, make
sure you are cutting in the middle and not cutting them too small.
•
If continuing with too much waste, shut down machine and move trim rollers 1/16”
closer or speed up trim rollers.
10. Open the pre-sizer a little bit at a time until desired size is being eliminated.
11. After making all necessary adjustments,
•
Adjust the elevator speed and increase capacity until you the desired rate.
Remember,
if you over crowd the table, your quality goes down
. You must give room for the
potatoes to turn before they come to the coulter blades.
•
Make necessary adjustment to accommodate the speed.
12. Confirm duster is putting on enough dust.
•
If dust is coming out of the corner of the discharge chute, slow down the dust.
•
If not enough, adjust the dust faster.
ALWAYS TAKE SAMPLES TO MAKE NECESSARY ADJUSTMENTS
