BELT TENSION
Pic. 13
Correct belt tension is paramount to a safe and reliable
air compressor. Too tight a belt can cause damage to
bearings and premature motor failure. These failures will
not be covered by warranty. Too loose a belt can cause
poor performance and excess heat due to slippage which
can also lead to premature component failure. This will not
be covered by warranty. To check the belt tension, gently
push down midway between the two pulleys the belt
should only move between 10mm – 15mm, Pic. 13.
If the belt moves more that this amount then you will need
to tighten the belt.
To adjust the belt tension, follow these simple steps;
1. Loosen the motor bolts, Pic. 13.
2. Slide the motor forward or backward to
correct position.
3. Tighten the motor bolts.
4. Check belt tension and repeat if needed.
5. If uncertain about attempting the above steps please
consult an authorised service agent.

BELT STRAIGHTNESS
Pic. 14
Belt straightness is paramount to a safe and reliable air
compressor. The belt should always run in a straight line
between the two (2) pulleys. If the belt is on an angle this
could cause excessive strain and wear on components.
This will not be covered by warranty. The belt should run
parallel to the two pulleys. If not, adjust.
To adjust the belt straightness, follow these simple steps;
1. Loosen the pump bolts, Pic. 14.
2. Slide the pump to the appropriate position.
3. Tighten the pump bolts.
4. Check belt straightness and repeat if needed.
5. Check belt tension and correct if necessary.
