UBRICATING PARTS
It is important to lubricate your key combinator regularly with a quality
#10 non-detergent motor oil. Signs that your combinator is overdue for
lubrication include:
■ squeaking sounds
■
corrosion
■
difficulty making keycuts
■
tightness in moving the operating lever.
Guidelines for
lubrication
To avoid damaging your combinator and causing inaccurate keycuts,
please adhere to the following:
■ Apply only enough oil to barely wet the appropriate points to avoid
overlubricating your combinator.
■
Do not lubricate the chip chute, the depth selector, or the roller on
the punch and die. Chips could stick to these parts, causing
malfunctions.
■
Do not apply any type of silicone-based lubricant to your
combinator. Doing so may void your warranty or service agreement.
■
Do not use an air hose to remove chips or dust from the key
combinator. Doing so may void your warranty or service agreement.
