General Service information
If the tool is not working properly, take it out of operation for inspection. Preventive maintenance is recom-
mended at regular intervals. See detailed information on preventive maintenance.
■
Make sure to use the service tools, service kits and spare parts recommended by Atlas Copco.
■
Make sure to follow the Service instructions provided by Atlas Copco on ServAid.
Make sure to work in a clean environment and that all parts are cleaned before re-assembling. For-
eign particles, even small fibers from paper tissue, may affect the service life of the Pulse unit.
Tightening of threaded connections
The tightening torque indicated in the exploded views will give the right clamping force and prevent parts
from loosening. It is important not to exceed the clamping force, these parts must be able to open up with-
out being damaged at service. After some time of operation and in special circumstances, depending on
application and usage, the parts may however loosen somewhat. The tightening torque can then be in-
creased by 10-20% and some type of low or medium thread locking fluid can be applied.
Maintenance instructions
Daily inspection
■
Make sure that the tool is in good condition, no visual damage.
■
Make sure that the air connection and air installation is done correctly. Listen for any air leakage.
■
Make sure that sockets and extensions have no visual damage.
■
Make sure to have the correct air pressure.
■
Listen to make sure that there is no unexpected noise when running the tool
Preventive maintenance
There are several criteria that affect the need for service on EP-tools such as; type of joint, torque level
and tightening duration, production rate, air pressure and air quality. Recommendations are based on a
“reference tightening” with listed criteria in table below. The service intervals and service solutions are
based on experience and internal testing.
Reference tightening
Tool size
Torque level of max
torque Tightening time
Production rate Tighten-
ings/ hour
EP 5-6 PTI 70-80 % 1 second 600
EP 7-8 PTI 70-80 % 1 second 600
EP 9 PTI 70-80 % TBD TBD
EP 11 PTI 70-80 % TBD TBD
EP 13 PTI 70-80 % 1,5 seconds 400
The air installation and air quality for the Reference tightening should be according to recommendations in
the Product Instructions. Deviations from above conditions may affect the service intervals.
