4.3.10 Check belt tension
 Too tight belt tension could damage shaft and shorten bearing life. Too loose belt tension may result in
damaging belt earlier and machine components due to overheat.
 Follow the procedure below to adjust tension of fan belt and belt for alternator.
 Adjust the tension by gradually loosening the fastening bolt of the alternator.
<Procedure>
① Visually check if there are any cracks or tears in
the belt.
② Adjust the belt tension by loosening the fixing
bolt“1”of the alternator so that the belt can
deflect 0.39 to 0.55 in.(10 to 14mm) when
pressed at the center of the belt with approx.
22lbf (98N) force.
③ Be careful not to leave any grease or LLC on a
belt while changing it. If any such material is
left, wipe it off completely.
4.4 Operation
 Do not operate the machine with service valves and relief valve
open unless air hoses and/or pipes are connected.
High-pressurized air blows out and its air pressure could cause
injury to the people nearby.
 When the machine has to be unavoidably temporarily operated
with its port open, be sure to mount a silencer to reduce noise and
wear protective materials such as earplugs to prevent damage to
hearing.
 Keep the door closed and locked while running the unit.
 When the door has to be opened, be careful not to touch portions
that are rotating or very hot.
Careless touch may cause serious injury.
 Pull the handle forward to open the door.
 Be sure to close the door tightly so that its latch is firmly caught.
