2.
Your drive belt is comi
ng apart or is frayed. Replace it.
3
. Your ball bearing cutter wheel shaft assembly is wearing out. With the machine turned
OFF—grab the cutter wheel’s left-hand nut and try to get some movement out of it.
There
should be absolutely no m
ovement—if there’s moveme
nt in the bearings you need to replace
th
e cutter shaft assembly. If there is not movement it may be the other bearing next to th
e
d
rive pulley—you will have to remove the drive belt to be able to check it out. If all seem
s
wel
l then you’re probably O.K. for a while
.
4.
The machine’s cutter shaft lock is partially depressed and is rubbing against the drive pulley.
Pull up on the shaft lo
ck knob.
Machine Won’t Start
There are several
things that can cause this besides the obvious—plug in the machine and check the
power line.
1. If you are running 12 Volt D.C.—check the fuse and ALL the wiring and connecti
ons.
2.
Key cuttings in the motor’s capacitor. Unplug the machine, remove the capacito
r’s rubber
cover and bl
ow out the chips. Remember to wear safety gl
asses.
3.
Remove the machine’s access plate—check the wiring connections and
switch. Repair or
replace as necessary.
4
. Cutter shaft lock is in the locked position.
Can’t Make Depth Adjustment
The problem is you’ve run out of room in the stylus assembly to make the adjustment because
You have one stop vise jaw in the standard configuration and other top vise jaw in the step
configuration.
1. M
ake sure both are install in the standard configuration and shoul
d be O.K.
2. You’ve had y
our cutter resharpened to many times and the diameter is too small to
work on
your machine.
Cutter Wheel Didn’t Seem to Last Long
Several things can cause this to happen.
1.
The cutter will last the longest
if it only duplicates brass keys.
2
. Premium quality Nickel-Silver key blanks are abrasive to the cutter wheel and will dull the cu
tter
m
ore rapidly than brass keys. Here’s what you can do to get the maximum life out of your cutte
r
wheel on these prem
ium
blanks.
a)
Duplicate them a little slower. Racing through the job, especially in
large rekeying jobs will put
m
ore wear on the cutter wheel than going a little slower. The machine’s high-speed “stick-sh
ift”
feature, extrem
ely powerful motor and extra large diameter cutter are a real temptation to push th
e
machine faster and faster.
b) You should charge a little bit m
ore money for cutting premium
key blanks and put that difference
aside for the purchase of a new cutter.
