Preventive Maintenance Level 1
Maintenance level 1
Carry out maintenance after 6.000.000 pulses, when POWER FOCUS 6000 is indicating “Pulse unit
oil level low” or once a year, whichever comes first.
For maximum tool performance follow below instructions and use recommended service tools and service
kits from Atlas Copco. Always use tightening torque and lubrications as recommended by Atlas Copco.
Tool Handle
■
Make a visual inspection for any damage.
■
Inspect the yoke and suspension points.
■
Inspect the ball bearing in the Pulse unit casing and the surface of the Anvil.
Electric Motor
■
Listen to any unexpected noise.
Pulse Unit
■
Change the oil accordingly, see Oil Filling and Changing Instruction for Pulse Unit.
■
Make sure that the pulsing frequency is within limits, see Tool Condition Test.
Preventive Maintenance Level 2
Maintenance level 2
Carry out maintenance after 12.000.000 pulses, when POWER FOCUS 6000 is indicating “Pulse
unit oil level low” or once a year, whichever comes first.
For maximum tool performance follow below instructions and use recommended service tools and service
kits from Atlas Copco. Always use tightening torque and lubrications as recommended by Atlas Copco.
Same as level 1 including additional Pulse unit maintenance below:
Pulse unit: Always use lint-free cloth when servicing the pulse unit
■
Drain all the oil completely from the Pulse unit.
■
Disassemble the Pulse unit (see spare parts list).
■
Clean and inspect all parts and surfaces thoroughly for any wear or damage.
■
Clean the magnets from any metal particles.
■
Replace both the rollers and pistons at the service interval, if any of them are worn.
■
Change all O-rings.
■
Replace the Anvil sealing. Make sure that the cylinder front piece is clean and dry on the inside with
no lubrication before assembling the new sealing.
■
Make sure that the Anvil surface is smooth, clean and lubricated with pulse oil to prevent damages to
the anvil sealing during assembly.
■
It is important that the cam shaft and the separator washer pin is lined up with the groove in the cylin-
der front piece. If not, the cylinder end piece will not be correctly fastened and the Pulse unit will not
function correctly.
■
Fill the Pulse unit to the right oil level, see Oil Filling and Changing Instruction for Pulse Unit.
Oil Level in the Pulse Unit
The right oil level in the Pulse unit is important for the tool to work correctly.
The need to add oil to the pulse unit will vary depending mainly on the number of tightenings, torque level
and number of pulses (tightening time).
Operating the tool on a low oil level will result in faster wear of the parts in the Pulse unit. It will also
effect the tool performance.
