L38GREB is our largest and heaviest grinder model, combining the convenience of a remote control with the flexibility of a powerful propane engine. More coverage in less time!
It is ideal for use on large commercial projects and offers the best productivity rates in the industry. Propane driven means no cables, no generators, no hassle. It can be used on new or old construction projects where power is not available.
GRINDER FEATURES:
- The super light, responsive and easy to use REMOTE CONTROL lets you operate the machine precisely at a steady speed and rpms, and allows you to move the vacuum, adjust cables, check floor without stopping the machine.
- NEW AND IMPROVED WATER SYSTEMwith gravity-fed water supply from the water tank and hose connection delivers more water under the machine for optimal wet grinding and simpler maintenance. There is no water pump or misting system on the new models.

GRINDING TIPS
- Overlap around 25% of the machine work path between passes.
- Check dust skirt to make sure it is all the way down, touching the floor to reduce airborne dust. Replace skirt if worn out or damaged.
- When starting machine hold it firmly and start moving (don’t keep it in one spot while heads are spinning).
- When stopping machine, keep moving until the grinding heads stop.
- To tilt machine up for tooling changes, move the weights back.
- To add more grinding pressure and grind more aggressively, put the weights down / forward.
- Always lock the weights during transportation.
Always use VAPOR tanks only with LAVINA machines. Do not fill over 80%, as this can cause freezing and pressure regulator damage. When propane grinders are used indoors, always make sure there is proper air ventilation with sufficient fresh air in the work area. Also make sure to maintain your equipment properly, such as changing air filters and oil regularly, etc. to reduce the risks of carbon monoxide. Using a CO monitor or badge is recommended. Read all warnings and information in your machine manual before operating any equipment.
