Checking Belt Tension - Makita MAC5500G Operating Instructions Manual

InStALLAtIOn & OPERAtIOn
ChECkInG bELt tEnSIOn
Adjust belt(s) so when pressure is applied at the center, there is approxi-
mately 1/2" slack (see diagram "Figure A" below).
If the belt is in-
stalled too tight,
the engine might
be overloaded.
This will cause
the engine to
overheat. If the
belt is installed
too loosely, it will
slip and excessive
wear and vibration
will occur.
hOw tO InStALL A nEw bELt If REQuIRED:
1) Turn off engine. Wait until engine is completely stopped
2) Remove belt guard.
) Loosen engine bolts and slide engine toward compressor head
just enough to allow old belt to be removed.
) Install proper replacement belt.
5) Slide engine away from compressor head to provide recommend-
ed tension as shown in diagram (Figure A.)
) Align belt using a straight edge ruler against pulley's edge.
) Fasten engine bolts.
8) Ensure engine and compressor pulley's are secure. Re-check
alignment.
9) Re-install belt guard.
10) Belt tension should be checked after 20 hours of operation.
Check tension monthly thereafter.
