Checking the tensioning bolts
WARNING Rupturing washers become
projectiles
Washers can rupture and cause serious injuries, if
you hit the heads of the tensioning bolts or the
washers.
► Never check the tensioning bolts by acoustic test,
but by visual test.
The visual check is only an indication. You can only
check doubtless in a repair shop after removing the
adapter plate and the elastic pad.
♦
Remove the covers of the service openings which
are placed at the top of the breaker box’s rear
side.
♦
Check the seat of the paint marks which are
placed on the heads of the tensioning bolts and
washers.
The paint marks have to be in your visual field. In
other cases, the respective tensioning bolt can be
loose or broken. In this case act as follows:
♦
Dismount the adapter plate and the elastic pad
(see chapter Removing the adapter plate).
♦
Check the tensioning bolt for tight fit.
♦
Tighten the loose tensioning bolt with the torque
required. (see chapter Bolt connections/Tightening
torques).
♦
Strip the old paint mark.
♦
Mark new the tighten tensioning bolt, the washer
and the cylinder cover with a colour cast of 10 mm
width vertically over all three parts. The paint mark
shall be seen in the centre of the service openings.
♦
Have broken tensioning bolts immediately
replaced.
♦
If you have any questions about replacement of
broken tensioning bolts, consult the Atlas Copco
Customer Center/Dealer in your area.
You can only check the front tensioning bolts, if you
dismount the adapter plate and the elastic pad (see
chapter Removing the adapter plate).
♦
Check the tensioning bolts weekly for tight fit.
