Maintenance (Continued)
COMPONENTS
Turn off all power and clean the air end, motor, fan blades, air lines, oil cooler and tank on a monthly basis.
BELTS
Lock out and tag the power then release all pressure from the tank to prevent unexpected movement of the unit.
Check belt tension every 3 months. Adjust belt tension to allow 3/8 inch deflection with normal thumb pressure. Also, align belts
using a straight edge against the face of the pulleys and touching the rim on both sides of the face. The belts should be parallel to this
straight edge.
Slots in the bed-plate allow for sliding the motor back and forth to adjust belt tension.
