Recommended Preventative Maintenance:
It is recommended that after every 200,000 pulsing seconds or 180 days, the fluid in the tool’s pulse unit be
changed. At such time, it is also recommended to grease the bearings in the air motor. If the presence of water is
noted, it is recommended that a small amount of oil be run through the air motor to wash out any rust residue in
the air motor.
It is also recommended that after every 400,000 pulsing seconds or 365 days, that a Pulse Unit Repair Kit be
installed in the pulse unit. This also allows the inspection of hard parts in the pulse unit.
