Safety Inspection Guide
The purpose of this inspection guide is to aid you in identifying
unsafe conditions.
Use good judgment to identify possible safety conditions not covered
by this inspection guide. Refer to the safety reminders for a general
checklist.
If any unsafe conditions exist, find out how serious the hazard could
be and if you can continue before you correct the hazard.
Check the following items:
•
Damaged, missing, or altered parts, especially in the area of the
On/Off switch and the power supply
•
Damaged, missing, or altered covers, especially in the area of
the top cover and the power supply cover
•
Possible safety exposure from any non-Lexmark attachments
Lubrication Specifications
Lubricate only when parts are replaced or as needed, not on a
scheduled basis. Use of lubricants other than those specified can
cause premature failure. Some unauthorized lubricants may
chemically attack polycarbonate parts. Use IBM no.10 oil PN
1280443 (approved equivalents: Mobil DTE27, Shell Tellus 100,
Fuchs Renolin MR30) to lubricate the areas of contact between:
