What makes the LMS88 GIR38 grease system “unique”?
It uses a centrifugal retention method that keeps gears lubricated longer than standard open-gear impact tools.
Is an external air lubricator required for this specific model?
Yes, to maintain the LMS88 GIR38‘s 7370 ft-lb peak, we strongly suggest an inline FRL (Filter-Regulator-Lubricator).
Can I use standard 1″ sockets with an adapter on this tool?
While possible, we advise using native 1-1/2″ impact sockets to prevent energy loss and adapter shearing.
Selection Advice: When should I choose the LMS88 over the RTP series?
Select the LMS88 GIR38 for high-speed disassembly where precision torque shut-off is less critical than raw power.
Installation Pro-Tip:
Ensure your compressor can sustain 70 cfm at 100 psi, or the tool will not reach its impact frequency.
