5 The V-belt should be checked after every 1000 hours. At the right tension, the
V-belt can easily be turned 45 degrees by hand. If tension is too high, strong
corrosion will occur or eventually the spindle of motor or pump may break. At
too little tension, the efficiency of the compressor decreases considerably.
Tightening the V-belt goes as follows:
Dismount the belt protector (3).
Unscrew the fastening bolts on
the motor sledge.
Remove the V-belt. Place the
motor at the wright distance from
the pump.
Make sure that the pulley of the
motor runs in the same line
parallel with the flywheel on the
pump (see drawing). Tighten
the fastening bolts and replace
the V-belt. Worn V-belts should
be replaced by new ones with
the same size.
6 Before maintenance of the fuel engine, first read the instruction manual of the
fuel engine.
Note:
Regular maintenance of your compressor will increase durability and
reliability.
