• Bolt-on compatible with Lincoln® Centro-Matic SL-11® injectors

Precision-honed Components for Reliable Operation in the Harshest Environments

System Setup Tips

• Run branches off main line and “Tee Out” to banks of injectors instead of in-series

• Locate injectors as close to bearings as possible to minimize line length to bearing to enable max pressure to reach injectors

• Place pressure switch beyond last injector

• Use large diameter tubing (1/4 in.) for bearing feed lines

• Make sure you have enough pressure to achieve normal 2,500 psi (172 bar)

• Make sure you vent down to the minimum reset pressure of your smallest injector

To adjust:

1. Loosen the lock nut

2. Rotate 5/8 inch output adjustment nut

clockwise to decrease grease output– decrease the travel of the piston
