What Should an Equipment Maintenance Log Include?

Each column below names what to record, what format works best, and why the column matters. Use one row per service event, not one row per piece of equipment. The column set is grounded in the documentation requirements of OSHA 29 CFR Part 1910.217, Section (e)(1)(ii) (mechanical power presses, which requires maintenance at manufacturer-specified intervals recorded by the responsible person) and IRS Publication 583 (which requires supporting records for deductions to be kept for at least three years from the filing date of the return).

OSHA 29 CFR Part 1910.217, Section (e)(1)(ii) requires that maintenance on mechanical power presses be performed at intervals specified in the manufacturer's instructions and recorded by the person responsible. Columns 4 (Interval), 7 (Done by), and 9 (Sign-off) directly satisfy that requirement for that equipment type. For equipment covered by OSHA 29 CFR Part 1910.147 (control of hazardous energy, lockout/tagout), the standard requires written energy-control procedures before maintenance on equipment that could unexpectedly energize; the maintenance log records that service was performed, while the lockout/tagout procedure is a separate safety document.

The manufacturer's operation and maintenance manual is the authoritative source for service intervals. It states each interval in the unit that applies to that piece of equipment: calendar time (months or years), usage (hours, miles, kilometers, or operating cycles), or a combination of both, whichever comes first. Substituting a different interval can void the warranty. For mechanical power presses, OSHA 29 CFR Part 1910.217, Section (e)(1)(ii) requires that the interval come from the manufacturer's instructions specifically.

To find the right interval for each service type:

1. Locate the maintenance schedule section of the manual. It is usually a table near the back of the manual, labeled 'Maintenance Schedule', 'Periodic Maintenance', or 'Lubrication and Maintenance Chart'.
2. Read the interval in the unit the manufacturer uses. An air compressor manual may state 'Change oil every 500 hours or 12 months, whichever comes first.' A delivery van manual may state 'Replace engine air filter every 15,000 miles or 12 months.' Record both conditions in the Interval column of your log so the next-due calculation is unambiguous.
3. Check for break-in intervals. New equipment often has a shorter first-service interval: for example, 'Change oil after the first 50 hours, then every 250 hours.' Note this in the log for new units so the first service is not missed.
4. If the manual is lost, search the manufacturer's website by model number. Most manufacturers publish PDF manuals by model. If no manual is available, contact the manufacturer's customer support line and ask for the recommended maintenance schedule in writing. File that written response with the log as the interval source.

Once you have the intervals documented, consider turning the maintenance schedule into a written standard operating procedure so any team member can follow it. See What Should a Standard Operating Procedure Include? for the seven fields an SOP needs, including a named owner and a trigger that says when the procedure runs. This maintenance log template extends that SOP by adding the nine columns that record each service event as a dated, signed row.

A maintenance log is only useful if it is kept consistently and completely. Three practices make the difference between a log that protects the business and one that creates a false sense of security.

One row per service event, always. Never overwrite a previous entry. A piece of equipment that has had ten oil changes should have ten rows. This is the only way to demonstrate that intervals were kept if an insurer or inspector asks for the service history. IRS Publication 583 (Starting a Business and Keeping Records) states that records supporting deductions should be kept for as long as the period of limitations applies, generally three years from the filing date of the return. Maintenance costs are typically deductible; the log is the supporting record. Keep the log for at least three years after the return is filed for the year in which the equipment was in service.

File vendor service receipts with the log. When a service vendor performs the work, attach their service receipt or work order to the log row. The receipt typically includes the technician's name, the parts used, and the date, which supplements your own log entry. Before a vendor works on your equipment for the first time, collect a certificate of insurance from them. A vendor working on your equipment creates liability exposure if they are injured on your premises or damage the equipment. See Which Specific Documents Does a New Vendor Need to Provide Before You Pay Them? for the seven documents to collect before the first payment, including the certificate of insurance and a signed contract. That checklist is grounded in IRS Section 6041 (the $600 threshold for Form 1099 reporting) and applies to maintenance vendors as much as to any other service provider.

Review the log on a fixed schedule. Set a monthly or quarterly calendar reminder to scan the 'Date next due' column and flag any service that is coming due within the next 30 days. This review takes less than ten minutes on a well-kept log and prevents the most common failure mode: a service that was due last month and nobody noticed.

If your business uses Dave by voolama (hellodave.ai), a managed AI workflow platform operated by voolama LLC, a technician can submit a completed service record through a User Interaction task in the Task Inbox (found under Tasks in the sidebar, accessible to users with the Admin or Use role). A manager with the Admin or Use role then reviews and signs off via a Human Review task. Every decision is logged with the acting user's identity and a timestamp in the per-tenant audit trail, supporting SOC 2 CC6.1 and GDPR Article 30 when those compliance modes are enabled. The Reports page (accessible to users with the Admin or Reporting role) shows four summary cards: Total Runs, Avg Latency, Failure Rate, and Pending Tasks. A workflow configured to generate a task when a next-due date passes would appear in the Pending Tasks count, making overdue maintenance visible at a glance. If you cannot see Reports in the sidebar, your role may not include Admin or Reporting: see Why Can't I See Agents, Workflows, or Other Sections in Dave by voolama? for the role access reference.

This template covers the fields a maintenance log needs and the practices that make it a genuine record. It does not cover:

• OSHA compliance for specific equipment types. OSHA 29 CFR Part 1910.217, Section (e)(1)(ii) is cited because it contains an explicit, narrow requirement for manufacturer-specified maintenance intervals recorded by the responsible person. It applies only to mechanical power presses. OSHA 29 CFR Part 1910.147 is cited because it governs energy isolation before maintenance on equipment that could unexpectedly energize, and requires written energy-control procedures. Many other OSHA standards govern other equipment types. Consult a qualified safety professional or your OSHA area office for compliance advice specific to your equipment and industry. The author of this template has a background in marketing technology and AI workflow operations, not in OSHA compliance or equipment maintenance.
• State and local regulations. Some states have maintenance documentation requirements that go beyond federal OSHA standards, particularly for vehicles operated on public roads and for equipment used in food service, healthcare, or construction. Check with your state labor department and any applicable licensing board.
• Warranty terms. Warranty coverage depends on the specific terms of your manufacturer's warranty. Keeping a maintenance log that follows the manufacturer's schedule is a necessary but not always sufficient condition for a warranty claim. Read your warranty documentation.
• Tax treatment of maintenance costs. IRS Publication 583 is cited for recordkeeping guidance only. How maintenance costs are deducted depends on your business structure, accounting method, and the nature of the equipment. Consult a qualified CPA or tax professional.
• Commercial interest disclosure. voolama LLC, which publishes this template, makes Dave by voolama, a workflow platform that businesses can use to route and log maintenance records. The template fields are grounded in OSHA 29 CFR Part 1910.217, Section (e)(1)(ii), OSHA 29 CFR Part 1910.147, and IRS Publication 583, not in voolama's commercial interests.
