Questions, Answered.
Warranty
What does the Lifetime Limited Warranty cover?
Defects in materials and workmanship on the major components, for as long as the original purchaser owns the machine:
- Main drive motor
- Gearbox and drive system
- Structural frame and chassis
- Internal electrical control components (excluding wear items)
You must register within 30 days
To activate coverage, register the equipment within thirty (30) days of the original purchase date.
Registration needs the machine's Unique Equipment Identifier (UEI) — it's on the nameplate, and it's the production date followed by additional characters printed on the plate.
Coverage is tied specifically to that registered UEI. Failing to register within 30 days may result in denial or limitation of coverage, and tampering with or altering the nameplate voids all coverage.
Original purchaser only — the warranty doesn't transfer
This Limited Warranty is extended exclusively to the original purchaser and is not transferable under any circumstances. It applies only to the person or legal entity named on the original sales invoice.
Any resale, transfer, lease, assignment, or change of ownership automatically voids all remaining coverage — including extended or lifetime protection plans — unless authorized in writing by Workhorse Grinders.
Proof of original purchase may be required to validate a claim.
What isn't covered
Normal wear items
- Tooling, belts, bearings, wheels, seals, brushes, cords, switches, fuses
Also excluded
- Damage from misuse, abuse, neglect, or improper maintenance
- Improper voltage, modification, or unauthorized repairs
- Operation outside intended use
- Cosmetic damage
- Freight, shipping, or transportation costs
- Labor costs, unless approved in writing
Workhorse reserves the right to determine whether a failure is due to a defect or to misuse.
How do I make a warranty claim?
If something breaks, don't sweat it. Three steps:
Remedy and limitation of liability
Remedy
Under the Lifetime Limited Warranty, Workhorse will, at its sole discretion, repair the defective component, provide replacement parts, or replace the unit if deemed necessary. This warranty is limited to parts replacement only unless otherwise approved in writing.
Limitation of liability
This warranty is limited to repair or replacement of defective components only. Workhorse shall not be liable for any indirect, incidental, consequential, or lost-profit damages arising from equipment failure.
Shipping & Delivery
Free shipping — commercial and residential
Free shipping to both commercial and residential addresses throughout the lower 48. No hidden freight fees, no surprises at checkout.
- Free freight shipping within the continental U.S.
- Delivery to commercial or residential addresses
- Secure crating and professional handling
- Delivery appointment coordination when required
Some residential or specialty deliveries may require lift-gate service or additional access coordination. If that applies, we handle it upfront and keep you in the loop — no last-minute headaches.
Inspect the crate before you sign
Once freight leaves our dock, the inspection at your end matters. Take a few minutes with the crate and equipment before signing the delivery receipt — look for visible damage, crushed corners, punctures, or signs of mishandling.
What to do if you see damage
Visible on arrival
- Note the damage clearly on the delivery receipt before signing
- Take photos of the crate and the machine
- Contact our support team immediately so we can help file a freight claim
Found after uncrating
- Notify us within 48 hours of delivery
- Send clear photos and a description of the issue
- Don't discard the packaging until we've reviewed the claim
If a valid freight issue occurs, we work with you and the carrier to resolve it as fast as possible — replacement parts, repair, or next steps.
Don't refuse the delivery
Unless the shipment is clearly destroyed or unsafe, don't refuse delivery without contacting us first. Refused shipments cause delays and additional freight charges.
If anything looks off, reach out right away — we've got your back.
Keeping It Running
When to replace your HEPA filter
Signs it's time
- Noticeable loss of suction
- Reduced airflow even after using the de-asher
- Increased motor strain or higher amp draw
- Visible dust bypass or leakage
- Filter stays heavily loaded after cleaning
Overused filters restrict airflow, cut dust containment efficiency, and strain the vacuum motor. Replacing on schedule keeps suction up and the machine alive longer — and keeps you OSHA-compliant on dust control.
When to replace your tooling
Signs it's time
- Slower grinding speed
- Increased machine vibration
- Uneven scratch pattern
- Excess heat or glazing
- Segment height visibly low or uneven
Running tooling too low kills productivity, damages backing plates, and strains the machine.
Which diamonds should I be running?
It comes down to three questions: what you're removing, how hard the concrete is, and how aggressive a finish you need. Those pick your pattern, your bond and your grit.
The short version — if you don't know your slab and it looks normal, start with a 4-Bar, Medium bond, 16 or 30 grit. Watch how the tooling cuts and wears, then adjust from there.
Our full walkthrough covers every pattern, bond and grit, plus a cheat sheet for common jobsite situations.
