ROUTINE MAINTENANCE
Filter Maintenance- the CR700 is equipped with a 100-mesh screen filter. This filter should be checked
periodically. A partially clogged filter will slow down the recovery rate of this unit.
Check the filter cartridge as follows:
• Use a 5/8” socket or boxed end wrench to loosen the suction port as shown in Figure 1.
• Once loose, remove the suction port- filter cartridge as shown in Figure 2.
• Either clean the current cartridge or replace with new cartridge.
• Inspect O-ring. Re-lubricate with compressor oil or equivalent.
• Place filter cartridge back into suction port fitting.
• Hand tighten this assembly back onto the CR700.
• Use a 5/8” socket or boxed end wrench to tighten 1/8 of a turn.
Do not over tighten, damage to the O-ring may occur.
• Check the connection for leaks.
