a) If adjusted to low your cutter wheel may cut into the right-hand vise jaw.
b) If adjusted to high your cutter wheel may not cut deep enough when cutting deep cuts in keys.
c) Carriage over travel will not prevent cutting the right-hand top vise jaw if the top vise jaw has come loose
and has moved forward into the cutter. PLEASE check the tightness of the knurled knobs OFTEN.

MAINTENANCE
UNPLUG YOUR MACHINE PRIOR TO MAINTENANCE
Your machine is time proven with good design, engineering and modern manufacturing practices. You can ser-
vice virtually
this key machine. Because Rytan manufactures the machines in-house you are assured a supply of new re-
placement parts and updates for as long as YOU want us to make the machines.
Keep your machine clean and lubricated and it will remain a productive asset to your business for a very long
time.
LUBRICATION
UNPLUG YOUR MACHINE PROIR TO LUBRICATION
You do not need to lubricate the motor or the cutter shaft bearings - these ball bearing assemblies are sealed
and lubricated for their lifetime.
Lubricate your machine as often as you like. Use number 30 non-detergent motor oil. Apply oil with a brush to
all black oxide processed steel surfaces. After applying the oil, let it stand overnight and wipe the oiled parts dry
the next day with a clean rag or soft paper towel. Turn the machine over and lubricate the linkages that drive
the carriage shaft left and right.
WARNING:
Do not turn the machine over and set it on the Power Switch.
SUGGESTION:
When lubricating the “stick-shift’ drive linkages under the machine you might want to use spray-
on bicycle chain lubricant – the kind that foams and penetrates.
DO NOT
use this on the rest of the machine.
Lubricate the vise jaw plungers inside the carriage – remove the key clamp knobs and large knurled knobs and
top vise jaws. Squirt some number 30 non-detergent motor oil in the large hold and reassemble.
DO NOT LUBRICATE
your key machine with LPS-1 or WD-40 in place of number 30 non-detergent motor oil.
You may use LPS-1 or WD-40 as a rust preventative in addition to the number 30 non-detergent motor oil. If
you only use LPS-1 or WD-40 as your machine’s lubricant you will eventually damage the machine. These
“lubricants” act more like solvents than lubricants – they work partially as a solvent that extracts already existing
oils from bearings and other parts and redistributes this existing oil along the surfaces that need oil. Eventually
you will exhaust all oil reserves in the machine’s parts and the machine will be operating as an oil-dry machine.
DO NOT
allow any oil or grease to get on the machine’s drive belt or pulleys. When handling these parts be
sure your hands are clean and free of any lubricants.
DRIVE BELT
Your machine’s belt tension is maintained by means of moving the motor. To adjust the belt tension - use your
7/16” Wrench and your 3/16” Allen Hex Wrench to loosen the four cap screws and hex nuts securing the motor
to the motor bracket. Push the motor hard against the belt and tighten the four screws. See figure 25.
