Tips on belt tightening:
• There will normally be a rapid drop in tension during
the run‐in period for new belts. When new belts are
fitted, check the tension every 2‐3 hours & adjust
until the tension remains constant.
• The best tension for V‐belt drives is the lowest
tension at which the belts do not slip or ratchet
under the highest load condition.

'h' value given in the table.
2 Ensure that the deflection force scale is zero'd by pushing the upper 'o'‐ring all the
way down.
3 Place the tension gauge in the centre of the belt span as shown in the diagram.
4 Press downwards on the rubber buffer, deflecting the belt until the underside of the
lower 'o'‐ring is level with the belt behind (use a straight edge if there is only 1 belt).
5 Take the reading from the deflection scale of the tension meter (read at the lower
edge of the 'o'‐ring) &
given in the table.
6 Tighten or loosen belts as required following procedure given in this operator's

• Too much tension shortens belt & bearing life.
• Too little tension will affect the performance of your
machine especially in respect of no‐stress devices.
• Ensure that belt drives are kept free of any foreign
materials.
• If a belt slips ‐ tighten it!
