5.7 Maintenance work on the machine
5.7.1 Cleaning
Clean the machine thoroughly daily.
Attention
–
After cleaning, check all cables, hoses, pipes and
screwed fittings for leaks, loose connections, chafe
marks and other damage.
–
Any faults which are detected should be rectified
immediately.
–
Do not use any flammable or aggressive substances for
cleaning purposes.
5.7.2 Torque information
The tightness categories relate to bolts with untreatet, unlibri-
cated surface.
The figures result in 90% exploitation of the limit of elasticity for a
friction coefficient µ
ges
=0.14.
Use a torque wrench to check that the tightening torques are
observed.
The figures indicated do not apply if lubricant MoS2 is used.
Hinweis
Self tighted nuts have to be replaced after every disassambly.
5.7.3 Screw connections
With vibration equipment, it is important to check the screwed
connections periodically to ensure that they are screwed tight.
Observe tightening torques.
5.7.4 Checking rubber buffer
Check the rubber buffer for cracks and fractures and for a tight fit;
replace immediately if damaged.
5.7.5 Checking V-belt
–
Remove V-belt guard.
–
Check V-belt for tension and condition.
–
Slacken the nuts of the rubber buffers on the outside.
–
Push the engine frame back.
x = ca. 10 mm (ca. 0.4 in)
Important
It is important to ensure that the frame is also actually pushed on
the rubber buffer contact surfaces and not just that the rubber
elements are stretched and then spring back. If necessary, apply
light blows with a hammer to knock the rubber buffers forward.
– Both buffers should be equally pre-tensioned.
–
Tighten nuts.
–
Crank the drive manually and recheck tension and correct if
necessary.
Danger
Do not start the engine without V-belt guard. Danger of
injuries.
–
Replace V-belt guard.
Important
Check the tension of the V-belt after 25 op. hrs. again. Adjust the
tension if necessary.
