Compressor Filter Element Replacement
To avoid residue accumulation in the reservoir and to protect the hydraulic components (valves,
pumps,motors, etc.), the filters must be serviced on a regular basis.
They must be changed after the initial 50-hours of new unit operation and every 200-hours
thereafter.To change filter elements:
1
Shut the gate valve and remove the filter element.
2
Install the new filter ensuring proper rubber seal seating and tighten as much as possible
using both hands.
3
Open the gate valve and check for leaks.
CAUTION
Avoid pump failure! Open the shutoff valve.
Drive Belt
To adjust the drive belt tension and alignment:
1
Loosen the four bolts securing the motor mounting bracket to the base plate.
2
Turn the drawbolt in a clockwise direction to tighten the belt until there is 1/4" - 1/2" play at
the center of the belt between the pulleys.
3
Adjust the alignment drawbolt until the motor pulley is square with the compressor. Use a
straightedge across the compressor pulley and check the gap between the motor pulley and
the straight edge. The gap (1-3/4") on the compressor side of the motor pulley should be the
same as on the far side of the pulley.
